Superpowers Release Notes
v5.1.0 (2026-04-30)
Removals
- Legacy slash commands removed —
/brainstorm, /execute-plan, and /write-plan are gone. They were deprecated stubs that did nothing but tell the user to invoke the corresponding skill. Invoke superpowers:brainstorming, superpowers:executing-plans, and superpowers:writing-plans directly instead. (#1188)
superpowers:code-reviewer named agent removed — the agent was the plugin's only named agent and was used by exactly two skills, while every other reviewer/implementer subagent in the repo dispatches general-purpose with a prompt template alongside its skill. The agent's persona and checklist have been merged into skills/requesting-code-review/code-reviewer.md as a self-contained Task-dispatch template. Anyone dispatching Task (superpowers:code-reviewer) should switch to Task (general-purpose) with the prompt template instead. (PR #1299)- Integration sections removed from skills — these were a legacy of the time before agents had native skills systems and didn't help with steering.
Worktree Skills Rewrite
using-git-worktrees and finishing-a-development-branch now detect when the agent is already running inside an isolated worktree and prefer the harness's native worktree controls before falling back to git worktree. Behavior was TDD-validated and cross-platform-checked across five harnesses. (PRI-974, PR #1121)
- Environment detection — both skills check
GIT_DIR != GIT_COMMON before doing anything; if already in a linked worktree, creation is skipped entirely. A submodule guard prevents false detection.
- Consent before creating worktrees —
using-git-worktrees no longer creates worktrees implicitly; the skill asks the user first. Fixes #991 (subagent-driven-development was auto-creating worktrees without consent).
- Native tool preference (Step 1a) — when the harness exposes its own worktree tool (e.g. Codex), the skill defers to it. The user's stated preference is respected when expressed.
- Provenance-based cleanup —
finishing-a-development-branch only cleans up worktrees inside .worktrees/ (created by superpowers); anything outside is left alone. Fixes #940 (Option 2 was incorrectly cleaning up worktrees), #999 (merge-then-remove ordering), and #238 (cd to repo root before git worktree remove).
- Detached HEAD handling — the finishing menu collapses to two options when there is no branch to merge from.
- Hardcoded
/Users/jesse paths in skill examples replaced with generic placeholders. (#858, PR #1122)
Contributor Guidelines for AI Agents
Two new sections at the top of CLAUDE.md (symlinked to AGENTS.md) speak directly to AI agents. An audit of the last 100 closed PRs against this repo showed a 94% rejection rate driven by AI-generated slop: agents that didn't read the PR template, opened duplicates, fabricated problem descriptions, or pushed fork- or domain-specific changes upstream.
- Pre-submission checklist — read the PR template, search for existing PRs, verify a real problem exists, confirm the change belongs in core, and show the human partner the complete diff before submitting.
- What we will not accept — third-party dependencies, "compliance" rewrites of skill content, project-specific configuration, bulk PRs, speculative fixes, domain-specific skills, fork-specific changes, fabricated content, and bundled unrelated changes.
- New harness PRs require a session transcript — most past new-harness integrations copied skill files or wrapped with
npx skills instead of loading the using-superpowers bootstrap at session start. The acceptance test ("Let's make a react todo list" must auto-trigger brainstorming in a clean session) and a complete transcript are now required.
New sync-to-codex-plugin script mirrors superpowers into the OpenAI Codex plugin marketplace as prime-radiant-inc/openai-codex-plugins. Path/user-agnostic so any team member can run it. (PR #1165)
- Clones the fork fresh into a temp directory per run, regenerates overlays inline, and opens a PR; auto-detects upstream from the script's own location and preflights
rsync/git/gh auth/python3.
--bootstrap flag for first-time setup; EXCLUDES patterns anchored to source root; assets/ excluded.- Mirrors
CODE_OF_CONDUCT.md; drops the agents/openai.yaml overlay.
- Seeds
interface.defaultPrompt in the mirrored plugin.json. (PR #1180 by @arittr)
- Codex plugin files are committed to the source repo so the sync script uses canonical versions; Codex marketplace metadata is preserved.
OpenCode
- Bootstrap content cached at module level —
getBootstrapContent() was calling fs.existsSync + fs.readFileSync + frontmatter regex on every agent step (the experimental.chat.messages.transform hook fires on every step in OpenCode's agent loop). Now read once, cached for the session lifetime, with a null sentinel for the missing-file case. 15 regression tests cover cache behavior, fs call counts, the injection guard, the missing-file sentinel, and cache reset. (Fixes #1202)
- Integration tests modernized.
- Install caveats clarified in the README.
Code Review Consolidation
requesting-code-review is now self-contained: the persona, checklist, and dispatch template live in skills/requesting-code-review/code-reviewer.md and the skill dispatches Task (general-purpose) directly. (PR #1299)
- Single source of truth — the persona/checklist that previously lived in both
agents/code-reviewer.md and the skill's placeholder template (and drifted independently) is now one file.
subagent-driven-development follows suit — its code-quality-reviewer-prompt.md now dispatches Task (general-purpose) instead of the named agent.- Behavioral test added —
tests/claude-code/test-requesting-code-review.sh plants real bugs (SQL injection, plaintext password handling, credential logging) into a tiny project and asserts the dispatched reviewer flags every planted issue at Critical/Important severity and refuses to approve the diff.
- Codex and Copilot workaround docs trimmed — the "Named agent dispatch" sections in
references/codex-tools.md and references/copilot-tools.md documented how to flatten a named agent into a generic dispatch. With no named agents shipping, the workaround is unnecessary; both sections were dropped.
Subagent-Driven Development
- No more pause every 3 tasks — the "review after each batch (3 tasks)" cadence in
requesting-code-review (originally for executing-plans) was leaking into subagent-driven-development. Replaced with "each task or at natural checkpoints" plus an explicit continuous-execution directive.
- SDD integration test now runs its assertions — three independent bugs caused the test to silently bail before printing any verification results: an unresolved
.. segment in the working-dir path, a set -euo pipefail interaction with find | sort | head -1 (SIGPIPE on the producer killed the script), and a missing --plugin-dir on the claude -p invocation that caused the test to load the installed plugin instead of the working tree. All three fixed; six verification tests now actually run against a real end-to-end SDD run.
Cursor
- Windows SessionStart hook routed through
run-hook.cmd instead of invoking the extensionless session-start script directly. Fixes Windows opening the file in an editor instead of running it. Also removed an accidental UTF-8 BOM from hooks-cursor.json.
Gemini CLI
- Subagent dispatch mapping — Gemini's
Task dispatch now maps to @agent-name / @generalist, with parallel subagent dispatch documented for independent tasks.
Skills
- Terminology cleanups across skill content.
Documentation & Install
- Factory Droid installation instructions added to README.
- Quickstart install links in README. (PR #1293 by @arittr)
- Codex plugin install guidance updated. (PR #1288 by @arittr)
- Codex
wait mapping corrected to wait_agent in the tools reference.
- Install order reorganized; Codex install instructions cleaned up.
- Removed vestigial
CHANGELOG.md in favor of RELEASE-NOTES.md as the single source. (PR #1163 by @shaanmajid)
- Discord invite link fixed; release announcements link and a detailed Discord description added to the Community section.
- @shaanmajid — vestigial
CHANGELOG.md removal (PR #1163)
- @arittr — README quickstart install links (#1293), Codex plugin install guidance (#1288),
sync-to-codex-plugin interface.defaultPrompt seed (#1180)
v5.0.7 (2026-03-31)
GitHub Copilot CLI Support
- SessionStart context injection — Copilot CLI v1.0.11 added support for
additionalContext in sessionStart hook output. The session-start hook now detects the COPILOT_CLI environment variable and emits the SDK-standard { "additionalContext": "..." } format, giving Copilot CLI users the full superpowers bootstrap at session start. (Original fix by @culinablaz in PR #910)
- Tool mapping — added
references/copilot-tools.md with the full Claude Code to Copilot CLI tool equivalence table
- Skill and README updates — added Copilot CLI to the
using-superpowers skill's platform instructions and README installation section
OpenCode Fixes
- Skills path consistency — the bootstrap text no longer advertises a misleading
configDir/skills/superpowers/ path that didn't match the runtime path. The agent should use the native skill tool, not navigate to files by path. Tests now use consistent paths derived from a single source of truth. (#847, #916)
- Bootstrap as user message — moved bootstrap injection from
experimental.chat.system.transform to experimental.chat.messages.transform, prepending to the first user message instead of adding a system message. Avoids token bloat from system messages repeated every turn (#750) and fixes compatibility with Qwen and other models that break on multiple system messages (#894).
v5.0.6 (2026-03-24)
Inline Self-Review Replaces Subagent Review Loops
The subagent review loop (dispatching a fresh agent to review plans/specs) doubled execution time (~25 min overhead) without measurably improving plan quality. Regression testing across 5 versions with 5 trials each showed identical quality scores regardless of whether the review loop ran.
- brainstorming — replaced Spec Review Loop (subagent dispatch + 3-iteration cap) with inline Spec Self-Review checklist: placeholder scan, internal consistency, scope check, ambiguity check
- writing-plans — replaced Plan Review Loop (subagent dispatch + 3-iteration cap) with inline Self-Review checklist: spec coverage, placeholder scan, type consistency
- writing-plans — added explicit "No Placeholders" section defining plan failures (TBD, vague descriptions, undefined references, "similar to Task N")
- Self-review catches 3-5 real bugs per run in ~30s instead of ~25 min, with comparable defect rates to the subagent approach
Brainstorm Server
- Session directory restructured — the brainstorm server session directory now contains two peer subdirectories:
content/ (HTML files served to the browser) and state/ (events, server-info, pid, log). Previously, server state and user interaction data were stored alongside served content, making them accessible over HTTP. The screen_dir and state_dir paths are both included in the server-started JSON. (Reported by 吉田仁)
Bug Fixes
- Owner-PID lifecycle fixes — the brainstorm server's owner-PID monitoring had two bugs causing false shutdowns within 60 seconds: (1) EPERM from cross-user PIDs (Tailscale SSH, etc.) was treated as "process dead", and (2) on WSL the grandparent PID resolves to a short-lived subprocess that exits before the first lifecycle check. Fixed by treating EPERM as "alive" and validating the owner PID at startup — if it's already dead, monitoring is disabled and the server relies on the 30-minute idle timeout. This also removes the Windows/MSYS2-specific carve-out from
start-server.sh since the server now handles it generically. (#879)
- writing-skills — corrected false claim that SKILL.md frontmatter supports "only two fields"; now says "two required fields" and links to the agentskills.io specification for all supported fields (PR #882 by @arittr)
Codex App Compatibility
- codex-tools — added named agent dispatch mapping documenting how to translate Claude Code's named agent types to Codex's
spawn_agent with worker roles (PR #647 by @arittr)
- codex-tools — added environment detection and Codex App finishing sections for worktree-aware skills (by @arittr)
- Design spec — added Codex App compatibility design spec (PRI-823) covering read-only environment detection, worktree-safe skill behavior, and sandbox fallback patterns (by @arittr)
v5.0.5 (2026-03-17)
Bug Fixes
- Brainstorm server ESM fix — renamed
server.js → server.cjs so the brainstorming server starts correctly on Node.js 22+ where the root package.json "type": "module" caused require() to fail. (PR #784 by @sarbojitrana, fixes #774, #780, #783)
- Brainstorm owner-PID on Windows — skip PID lifecycle monitoring on Windows/MSYS2 where the PID namespace is invisible to Node.js, preventing the server from self-terminating after 60 seconds. (#770, docs from PR #768 by @lucasyhzlu-debug)
- stop-server.sh reliability — verify the server process actually died before reporting success. SIGTERM + 2s wait + SIGKILL fallback. (#723)
Changed
- Execution handoff — restore user choice between subagent-driven and inline execution after plan writing. Subagent-driven is recommended but no longer mandatory.
v5.0.4 (2026-03-16)
Review Loop Refinements
Dramatically reduces token usage and speeds up spec and plan reviews by eliminating unnecessary review passes and tightening reviewer focus.
- Single whole-plan review — plan reviewer now reviews the complete plan in one pass instead of chunk-by-chunk. Removed all chunk-related concepts (
## Chunk N: headings, 1000-line chunk limits, per-chunk dispatch).
- Raised the bar for blocking issues — both spec and plan reviewer prompts now include a "Calibration" section: only flag issues that would cause real problems during implementation. Minor wording, stylistic preferences, and formatting quibbles should not block approval.
- Reduced max review iterations — from 5 to 3 for both spec and plan review loops. If the reviewer is calibrated correctly, 3 rounds is plenty.
- Streamlined reviewer checklists — spec reviewer trimmed from 7 categories to 5; plan reviewer from 7 to 4. Removed formatting-focused checks (task syntax, chunk size) in favor of substance (buildability, spec alignment).
OpenCode
- One-line plugin install — OpenCode plugin now auto-registers the skills directory via a
config hook. No symlinks or skills.paths config needed. Install is just adding one line to opencode.json. (PR #753)
- Added
package.json so OpenCode can install superpowers as an npm package from git.
Bug Fixes
- Verify server actually stopped —
stop-server.sh now confirms the process is dead before reporting success. SIGTERM + 2s wait + SIGKILL fallback. Reports failure if the process survives. (PR #751)
- Generic agent language — brainstorm companion waiting page now says "the agent" instead of "Claude".
v5.0.3 (2026-03-15)
Cursor Support
- Cursor hooks — added
hooks/hooks-cursor.json with Cursor's camelCase format (sessionStart, version: 1) and updated .cursor-plugin/plugin.json to reference it. Fixed platform detection in session-start to check CURSOR_PLUGIN_ROOT first (Cursor may also set CLAUDE_PLUGIN_ROOT). (Based on PR #709)
Bug Fixes
- Stop firing SessionStart hook on
--resume — the startup hook was re-injecting context on resumed sessions, which already have the context in their conversation history. The hook now fires only on startup, clear, and compact.
- Bash 5.3+ hook hang — replaced heredoc (
cat <<EOF) with printf in hooks/session-start. Fixes indefinite hang on macOS with Homebrew bash 5.3+ caused by a bash regression with large variable expansion in heredocs. (#572, #571)
- POSIX-safe hook script — replaced
${BASH_SOURCE[0]:-$0} with $0 in hooks/session-start. Fixes "Bad substitution" error on Ubuntu/Debian where /bin/sh is dash. (#553)
- Portable shebangs — replaced
#!/bin/bash with #!/usr/bin/env bash in all shell scripts. Fixes execution on NixOS, FreeBSD, and macOS with Homebrew bash where /bin/bash is outdated or missing. (#700)
- Brainstorm server on Windows — auto-detect Windows/Git Bash (
OSTYPE=msys*, MSYSTEM) and switch to foreground mode, fixing silent server failure caused by nohup/disown process reaping. (#737)
- Codex docs fix — replaced deprecated
collab flag with multi_agent in Codex documentation. (PR #749)
v5.0.2 (2026-03-11)
Zero-Dependency Brainstorm Server
Removed all vendored node_modules — server.js is now fully self-contained
- Replaced Express/Chokidar/WebSocket dependencies with zero-dependency Node.js server using built-in
http, fs, and crypto modules
- Removed ~1,200 lines of vendored
node_modules/, package.json, and package-lock.json
- Custom WebSocket protocol implementation (RFC 6455 framing, ping/pong, proper close handshake)
- Native
fs.watch() file watching replaces Chokidar
- Full test suite: HTTP serving, WebSocket protocol, file watching, and integration tests
Brainstorm Server Reliability
- Auto-exit after 30 minutes idle — server shuts down when no clients are connected, preventing orphaned processes
- Owner process tracking — server monitors the parent harness PID and exits when the owning session dies
- Liveness check — skill verifies server is responsive before reusing an existing instance
- Encoding fix — proper
<meta charset="utf-8"> on served HTML pages
Subagent Context Isolation
- All delegation skills (brainstorming, dispatching-parallel-agents, requesting-code-review, subagent-driven-development, writing-plans) now include context isolation principle
- Subagents receive only the context they need, preventing context window pollution
v5.0.1 (2026-03-10)
Agentskills Compliance
Brainstorm-server moved into skill directory
- Moved
lib/brainstorm-server/ → skills/brainstorming/scripts/ per the agentskills.io specification
- All
${CLAUDE_PLUGIN_ROOT}/lib/brainstorm-server/ references replaced with relative scripts/ paths
- Skills are now fully portable across platforms — no platform-specific env vars needed to locate scripts
lib/ directory removed (was the last remaining content)
New Features
Gemini CLI extension
- Native Gemini CLI extension support via
gemini-extension.json and GEMINI.md at repo root
GEMINI.md @imports using-superpowers skill and tool mapping table at session start- Gemini CLI tool mapping reference (
skills/using-superpowers/references/gemini-tools.md) — translates Claude Code tool names (Read, Write, Edit, Bash, etc.) to Gemini CLI equivalents (read_file, write_file, replace, etc.)
- Documents Gemini CLI limitations: no subagent support, skills fall back to
executing-plans
- Extension root at repo root for cross-platform compatibility (avoids Windows symlink issues)
- Install instructions added to README
Improvements
Multi-platform brainstorm server launch
- Per-platform launch instructions in visual-companion.md: Claude Code (default mode), Codex (auto-foreground via
CODEX_CI), Gemini CLI (--foreground with is_background), and fallback for other environments
- Server now writes startup JSON to
$SCREEN_DIR/.server-info so agents can find the URL and port even when stdout is hidden by background execution
Brainstorm server dependencies bundled
node_modules vendored into the repo so the brainstorm server works immediately on fresh plugin installs without requiring npm at runtime- Removed
fsevents from bundled deps (macOS-only native binary; chokidar falls back gracefully without it)
- Fallback auto-install via
npm install if node_modules is missing
OpenCode tool mapping fix
TodoWrite → todowrite (was incorrectly mapped to update_plan); verified against OpenCode source
Bug Fixes
Windows/Linux: single quotes break SessionStart hook (#577, #529, #644, PR #585)
- Single quotes around
${CLAUDE_PLUGIN_ROOT} in hooks.json fail on Windows (cmd.exe doesn't recognize single quotes as path delimiters) and on Linux (single quotes prevent variable expansion)
- Fix: replaced single quotes with escaped double quotes — works across macOS bash, Windows cmd.exe, Windows Git Bash, and Linux, with and without spaces in paths
- Verified on Windows 11 (NT 10.0.26200.0) with Claude Code 2.1.72 and Git for Windows
Brainstorming spec review loop skipped (#677)
- The spec review loop (dispatch spec-document-reviewer subagent, iterate until approved) existed in the prose "After the Design" section but was missing from the checklist and process flow diagram
- Since agents follow the diagram and checklist more reliably than prose, the spec review step was being skipped entirely
- Added step 7 (spec review loop) to the checklist and corresponding nodes to the dot graph
- Tested with
claude --plugin-dir and claude-session-driver: worker now correctly dispatches the reviewer
Cursor install command (PR #676)
- Fixed Cursor install command in README:
/plugin-add → /add-plugin (confirmed via Cursor 2.5 release announcement)
User review gate in brainstorming (#565)
- Added explicit user review step between spec completion and writing-plans handoff
- User must approve the spec before implementation planning begins
- Checklist, process flow, and prose updated with the new gate
Session-start hook emits context only once per platform
- Hook now detects whether it's running in Claude Code or another platform
- Emits
hookSpecificOutput for Claude Code, additional_context for others — prevents double context injection
Linting fix in token analysis script
except: → except Exception: in tests/claude-code/analyze-token-usage.py
Maintenance
Removed dead code
- Deleted
lib/skills-core.js and its test (tests/opencode/test-skills-core.js) — unused since February 2026
- Removed skills-core existence check from
tests/opencode/test-plugin-loading.sh
- @karuturi — Claude Code official marketplace install instructions (PR #610)
- @mvanhorn — session-start hook dual-emit fix, OpenCode tool mapping fix
- @daniel-graham — linting fix for bare except
- PR #585 author — Windows/Linux hooks quoting fix
v5.0.0 (2026-03-09)
Breaking Changes
Specs and plans directory restructured
- Specs (brainstorming output) now save to
docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md
- Plans (writing-plans output) now save to
docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md
- User preferences for spec/plan locations override these defaults
- All internal skill references, test files, and example paths updated to match
- Migration: move existing files from
docs/plans/ to new locations if desired
Subagent-driven development mandatory on capable harnesses
Writing-plans no longer offers a choice between subagent-driven and executing-plans. On harnesses with subagent support (Claude Code, Codex), subagent-driven-development is required. Executing-plans is reserved for harnesses without subagent capability, and now tells the user that Superpowers works better on a subagent-capable platform.
Executing-plans no longer batches
Removed the "execute 3 tasks then stop for review" pattern. Plans now execute continuously, stopping only for blockers.
Slash commands deprecated
/brainstorm, /write-plan, and /execute-plan now show deprecation notices pointing users to the corresponding skills. Commands will be removed in the next major release.
New Features
Visual brainstorming companion
Optional browser-based companion for brainstorming sessions. When a topic would benefit from visuals, the brainstorming skill offers to show mockups, diagrams, comparisons, and other content in a browser window alongside terminal conversation.
lib/brainstorm-server/ — WebSocket server with browser helper library, session management scripts, and dark/light themed frame template ("Superpowers Brainstorming" with GitHub link)skills/brainstorming/visual-companion.md — Progressive disclosure guide for server workflow, screen authoring, and feedback collection- Brainstorming skill adds a visual companion decision point to its process flow: after exploring project context, the skill evaluates whether upcoming questions involve visual content and offers the companion in its own message
- Per-question decision: even after accepting, each question is evaluated for whether browser or terminal is more appropriate
- Integration tests in
tests/brainstorm-server/
Document review system
Automated review loops for spec and plan documents using subagent dispatch:
skills/brainstorming/spec-document-reviewer-prompt.md — Reviewer checks completeness, consistency, architecture, and YAGNIskills/writing-plans/plan-document-reviewer-prompt.md — Reviewer checks spec alignment, task decomposition, file structure, and file size- Brainstorming dispatches spec reviewer after writing the design doc
- Writing-plans includes chunk-based plan review loop after each section
- Review loops repeat until approved or escalate after 5 iterations
- End-to-end tests in
tests/claude-code/test-document-review-system.sh
- Design spec and implementation plan in
docs/superpowers/
Architecture guidance across the skill pipeline
Design-for-isolation and file-size-awareness guidance added to brainstorming, writing-plans, and subagent-driven-development:
- Brainstorming — New sections: "Design for isolation and clarity" (clear boundaries, well-defined interfaces, independently testable units) and "Working in existing codebases" (follow existing patterns, targeted improvements only)
- Writing-plans — New "File Structure" section: map out files and responsibilities before defining tasks. New "Scope Check" backstop: catch multi-subsystem specs that should have been decomposed during brainstorming
- SDD implementer — New "Code Organization" section (follow plan's file structure, report concerns about growing files) and "When You're in Over Your Head" escalation guidance
- SDD code quality reviewer — Now checks architecture, unit decomposition, plan conformance, and file growth
- Spec/plan reviewers — Architecture and file size added to review criteria
- Scope assessment — Brainstorming now assesses whether a project is too large for a single spec. Multi-subsystem requests are flagged early and decomposed into sub-projects, each with its own spec → plan → implementation cycle
Subagent-driven development improvements
- Model selection — Guidance for choosing model capability by task type: cheap models for mechanical implementation, standard for integration, capable for architecture and review
- Implementer status protocol — Subagents now report DONE, DONE_WITH_CONCERNS, BLOCKED, or NEEDS_CONTEXT. Controller handles each status appropriately: re-dispatching with more context, upgrading model capability, breaking tasks apart, or escalating to human
Improvements
Instruction priority hierarchy
Added explicit priority ordering to using-superpowers:
- User's explicit instructions (CLAUDE.md, AGENTS.md, direct requests) — highest priority
- Superpowers skills — override default system behavior
- Default system prompt — lowest priority
If CLAUDE.md or AGENTS.md says "don't use TDD" and a skill says "always use TDD," the user's instructions win.
SUBAGENT-STOP gate
Added <SUBAGENT-STOP> block to using-superpowers. Subagents dispatched for specific tasks now skip the skill instead of activating the 1% rule and invoking full skill workflows.
Multi-platform improvements
- Codex tool mapping moved to progressive disclosure reference file (
references/codex-tools.md)
- Platform Adaptation pointer added so non-Claude-Code platforms can find tool equivalents
- Plan headers now address "agentic workers" instead of "Claude" specifically
- Collab feature requirement documented in
docs/README.codex.md
Writing-plans template updates
- Plan steps now use checkbox syntax (
- [ ] **Step N:**) for progress tracking
- Plan header references both subagent-driven-development and executing-plans with platform-aware routing
v4.3.1 (2026-02-21)
Added
Cursor support
Superpowers now works with Cursor's plugin system. Includes a .cursor-plugin/plugin.json manifest and Cursor-specific installation instructions in the README. The SessionStart hook output now includes an additional_context field alongside the existing hookSpecificOutput.additionalContext for Cursor hook compatibility.
Fixed
Windows: Restored polyglot wrapper for reliable hook execution (#518, #504, #491, #487, #466, #440)
Claude Code's .sh auto-detection on Windows was prepending bash to the hook command, breaking execution. The fix:
- Renamed
session-start.sh to session-start (extensionless) so auto-detection doesn't interfere
- Restored
run-hook.cmd polyglot wrapper with multi-location bash discovery (standard Git for Windows paths, then PATH fallback)
- Exits silently if no bash is found rather than erroring
- On Unix, the wrapper runs the script directly via
exec bash
- Uses POSIX-safe
dirname "$0" path resolution (works on dash/sh, not just bash)
This fixes SessionStart failures on Windows with spaces in paths, missing WSL, set -euo pipefail fragility on MSYS, and backslash mangling.
v4.3.0 (2026-02-12)
This fix should dramatically improve superpowers skills compliance and should reduce the chances of Claude entering its native plan mode unintentionally.
Changed
Brainstorming skill now enforces its workflow instead of describing it
Models were skipping the design phase and jumping straight to implementation skills like frontend-design, or collapsing the entire brainstorming process into a single text block. The skill now uses hard gates, a mandatory checklist, and a graphviz process flow to enforce compliance:
<HARD-GATE>: no implementation skills, code, or scaffolding until design is presented and user approves- Explicit checklist (6 items) that must be created as tasks and completed in order
- Graphviz process flow with
writing-plans as the only valid terminal state
- Anti-pattern callout for "this is too simple to need a design" — the exact rationalization models use to skip the process
- Design section sizing based on section complexity, not project complexity
Using-superpowers workflow graph intercepts EnterPlanMode
Added an EnterPlanMode intercept to the skill flow graph. When the model is about to enter Claude's native plan mode, it checks whether brainstorming has happened and routes through the brainstorming skill instead. Plan mode is never entered.
Fixed
SessionStart hook now runs synchronously
Changed async: true to async: false in hooks.json. When async, the hook could fail to complete before the model's first turn, meaning using-superpowers instructions weren't in context for the first message.
v4.2.0 (2026-02-05)
Breaking Changes
Codex: Replaced bootstrap CLI with native skill discovery
The superpowers-codex bootstrap CLI, Windows .cmd wrapper, and related bootstrap content file have been removed. Codex now uses native skill discovery via ~/.agents/skills/superpowers/ symlink, so the old use_skill/find_skills CLI tools are no longer needed.
Installation is now just clone + symlink (documented in INSTALL.md). No Node.js dependency required. The old ~/.codex/skills/ path is deprecated.
Fixes
Windows: Fixed Claude Code 2.1.x hook execution (#331)
Claude Code 2.1.x changed how hooks execute on Windows: it now auto-detects .sh files in commands and prepends bash. This broke the polyglot wrapper pattern because bash "run-hook.cmd" session-start.sh tries to execute the .cmd file as a bash script.
Fix: hooks.json now calls session-start.sh directly. Claude Code 2.1.x handles the bash invocation automatically. Also added .gitattributes to enforce LF line endings for shell scripts (fixes CRLF issues on Windows checkout).
Windows: SessionStart hook runs async to prevent terminal freeze (#404, #413, #414, #419)
The synchronous SessionStart hook blocked the TUI from entering raw mode on Windows, freezing all keyboard input. Running the hook async prevents the freeze while still injecting superpowers context.
Windows: Fixed O(n^2) escape_for_json performance
The character-by-character loop using ${input:$i:1} was O(n^2) in bash due to substring copy overhead. On Windows Git Bash this took 60+ seconds. Replaced with bash parameter substitution (${s//old/new}) which runs each pattern as a single C-level pass — 7x faster on macOS, dramatically faster on Windows.
Codex: Fixed Windows/PowerShell invocation (#285, #243)
- Windows doesn't respect shebangs, so directly invoking the extensionless
superpowers-codex script triggered an "Open with" dialog. All invocations now prefixed with node.
- Fixed
~/ path expansion on Windows — PowerShell doesn't expand ~ when passed as an argument to node. Changed to $HOME which expands correctly in both bash and PowerShell.
Codex: Fixed path resolution in installer
Used fileURLToPath() instead of manual URL pathname parsing to correctly handle paths with spaces and special characters on all platforms.
Codex: Fixed stale skills path in writing-skills
Updated ~/.codex/skills/ reference (deprecated) to ~/.agents/skills/ for native discovery.
Improvements
Worktree isolation now required before implementation
Added using-git-worktrees as a required skill for both subagent-driven-development and executing-plans. Implementation workflows now explicitly require setting up an isolated worktree before starting work, preventing accidental work directly on main.
Main branch protection softened to require explicit consent
Instead of prohibiting main branch work entirely, the skills now allow it with explicit user consent. More flexible while still ensuring users are aware of the implications.
Simplified installation verification
Removed /help command check and specific slash command list from verification steps. Skills are primarily invoked by describing what you want to do, not by running specific commands.
Codex: Clarified subagent tool mapping in bootstrap
Improved documentation of how Codex tools map to Claude Code equivalents for subagent workflows.
Tests
- Added worktree requirement test for subagent-driven-development
- Added main branch red flag warning test
- Fixed case sensitivity in skill recognition test assertions
v4.1.1 (2026-01-23)
Fixes
OpenCode: Standardized on plugins/ directory per official docs (#343)
OpenCode's official documentation uses ~/.config/opencode/plugins/ (plural). Our docs previously used plugin/ (singular). While OpenCode accepts both forms, we've standardized on the official convention to avoid confusion.
Changes:
- Renamed
.opencode/plugin/ to .opencode/plugins/ in repo structure
- Updated all installation docs (INSTALL.md, README.opencode.md) across all platforms
- Updated test scripts to match
OpenCode: Fixed symlink instructions (#339, #342)
- Added explicit
rm before ln -s (fixes "file already exists" errors on reinstall)
- Added missing skills symlink step that was absent from INSTALL.md
- Updated from deprecated
use_skill/find_skills to native skill tool references
v4.1.0 (2026-01-23)
Breaking Changes
OpenCode: Switched to native skills system
Superpowers for OpenCode now uses OpenCode's native skill tool instead of custom use_skill/find_skills tools. This is a cleaner integration that works with OpenCode's built-in skill discovery.
Migration required: Skills must be symlinked to ~/.config/opencode/skills/superpowers/ (see updated installation docs).
Fixes
OpenCode: Fixed agent reset on session start (#226)
The previous bootstrap injection method using session.prompt({ noReply: true }) caused OpenCode to reset the selected agent to "build" on first message. Now uses experimental.chat.system.transform hook which modifies the system prompt directly without side effects.
OpenCode: Fixed Windows installation (#232)
- Removed dependency on
skills-core.js (eliminates broken relative imports when file is copied instead of symlinked)
- Added comprehensive Windows installation docs for cmd.exe, PowerShell, and Git Bash
- Documented proper symlink vs junction usage for each platform
Claude Code: Fixed Windows hook execution for Claude Code 2.1.x
Claude Code 2.1.x changed how hooks execute on Windows: it now auto-detects .sh files in commands and prepends bash . This broke the polyglot wrapper pattern because bash "run-hook.cmd" session-start.sh tries to execute the .cmd file as a bash script.
Fix: hooks.json now calls session-start.sh directly. Claude Code 2.1.x handles the bash invocation automatically. Also added .gitattributes to enforce LF line endings for shell scripts (fixes CRLF issues on Windows checkout).
v4.0.3 (2025-12-26)
Improvements
Strengthened using-superpowers skill for explicit skill requests
Addressed a failure mode where Claude would skip invoking a skill even when the user explicitly requested it by name (e.g., "subagent-driven-development, please"). Claude would think "I know what that means" and start working directly instead of loading the skill.
Changes:
- Updated "The Rule" to say "Invoke relevant or requested skills" instead of "Check for skills" - emphasizing active invocation over passive checking
- Added "BEFORE any response or action" - the original wording only mentioned "response" but Claude would sometimes take action without responding first
- Added reassurance that invoking a wrong skill is okay - reduces hesitation
- Added new red flag: "I know what that means" → Knowing the concept ≠ using the skill
Added explicit skill request tests
New test suite in tests/explicit-skill-requests/ that verifies Claude correctly invokes skills when users request them by name. Includes single-turn and multi-turn test scenarios.
v4.0.2 (2025-12-23)
Fixes
Slash commands now user-only
Added disable-model-invocation: true to all three slash commands (/brainstorm, /execute-plan, /write-plan). Claude can no longer invoke these commands via the Skill tool—they're restricted to manual user invocation only.
The underlying skills (superpowers:brainstorming, superpowers:executing-plans, superpowers:writing-plans) remain available for Claude to invoke autonomously. This change prevents confusion when Claude would invoke a command that just redirects to a skill anyway.
v4.0.1 (2025-12-23)
Fixes
Clarified how to access skills in Claude Code
Fixed a confusing pattern where Claude would invoke a skill via the Skill tool, then try to Read the skill file separately. The using-superpowers skill now explicitly states that the Skill tool loads skill content directly—no need to read files.
- Added "How to Access Skills" section to
using-superpowers
- Changed "read the skill" → "invoke the skill" in instructions
- Updated slash commands to use fully qualified skill names (e.g.,
superpowers:brainstorming)
Added GitHub thread reply guidance to receiving-code-review (h/t @ralphbean)
Added a note about replying to inline review comments in the original thread rather than as top-level PR comments.
Added automation-over-documentation guidance to writing-skills (h/t @EthanJStark)
Added guidance that mechanical constraints should be automated, not documented—save skills for judgment calls.
v4.0.0 (2025-12-17)
New Features
Two-stage code review in subagent-driven-development
Subagent workflows now use two separate review stages after each task:
-
Spec compliance review - Skeptical reviewer verifies implementation matches spec exactly. Catches missing requirements AND over-building. Won't trust implementer's report—reads actual code.
-
Code quality review - Only runs after spec compliance passes. Reviews for clean code, test coverage, maintainability.
This catches the common failure mode where code is well-written but doesn't match what was requested. Reviews are loops, not one-shot: if reviewer finds issues, implementer fixes them, then reviewer checks again.
Other subagent workflow improvements:
- Controller provides full task text to workers (not file references)
- Workers can ask clarifying questions before AND during work
- Self-review checklist before reporting completion
- Plan read once at start, extracted to TodoWrite
New prompt templates in skills/subagent-driven-development/:
implementer-prompt.md - Includes self-review checklist, encourages questionsspec-reviewer-prompt.md - Skeptical verification against requirementscode-quality-reviewer-prompt.md - Standard code review
Debugging techniques consolidated with tools
systematic-debugging now bundles supporting techniques and tools:
root-cause-tracing.md - Trace bugs backward through call stackdefense-in-depth.md - Add validation at multiple layerscondition-based-waiting.md - Replace arbitrary timeouts with condition pollingfind-polluter.sh - Bisection script to find which test creates pollutioncondition-based-waiting-example.ts - Complete implementation from real debugging session
Testing anti-patterns reference
test-driven-development now includes testing-anti-patterns.md covering:
- Testing mock behavior instead of real behavior
- Adding test-only methods to production classes
- Mocking without understanding dependencies
- Incomplete mocks that hide structural assumptions
Skill test infrastructure
Three new test frameworks for validating skill behavior:
tests/skill-triggering/ - Validates skills trigger from naive prompts without explicit naming. Tests 6 skills to ensure descriptions alone are sufficient.
tests/claude-code/ - Integration tests using claude -p for headless testing. Verifies skill usage via session transcript (JSONL) analysis. Includes analyze-token-usage.py for cost tracking.
tests/subagent-driven-dev/ - End-to-end workflow validation with two complete test projects:
go-fractals/ - CLI tool with Sierpinski/Mandelbrot (10 tasks)svelte-todo/ - CRUD app with localStorage and Playwright (12 tasks)
Major Changes
DOT flowcharts as executable specifications
Rewrote key skills using DOT/GraphViz flowcharts as the authoritative process definition. Prose becomes supporting content.
The Description Trap (documented in writing-skills): Discovered that skill descriptions override flowchart content when descriptions contain workflow summaries. Claude follows the short description instead of reading the detailed flowchart. Fix: descriptions must be trigger-only ("Use when X") with no process details.
Skill priority in using-superpowers
When multiple skills apply, process skills (brainstorming, debugging) now explicitly come before implementation skills. "Build X" triggers brainstorming first, then domain skills.
brainstorming trigger strengthened
Description changed to imperative: "You MUST use this before any creative work—creating features, building components, adding functionality, or modifying behavior."
Breaking Changes
Skill consolidation - Six standalone skills merged:
root-cause-tracing, defense-in-depth, condition-based-waiting → bundled in systematic-debugging/testing-skills-with-subagents → bundled in writing-skills/testing-anti-patterns → bundled in test-driven-development/sharing-skills removed (obsolete)
Other Improvements
- render-graphs.js - Tool to extract DOT diagrams from skills and render to SVG
- Rationalizations table in using-superpowers - Scannable format including new entries: "I need more context first", "Let me explore first", "This feels productive"
- docs/testing.md - Guide to testing skills with Claude Code integration tests
v3.6.2 (2025-12-03)
Fixed
- Linux Compatibility: Fixed polyglot hook wrapper (
run-hook.cmd) to use POSIX-compliant syntax
- Replaced bash-specific
${BASH_SOURCE[0]:-$0} with standard $0 on line 16
- Resolves "Bad substitution" error on Ubuntu/Debian systems where
/bin/sh is dash
- Fixes #141
v3.5.1 (2025-11-24)
Changed
- OpenCode Bootstrap Refactor: Switched from
chat.message hook to session.created event for bootstrap injection
- Bootstrap now injects at session creation via
session.prompt() with noReply: true
- Explicitly tells the model that using-superpowers is already loaded to prevent redundant skill loading
- Consolidated bootstrap content generation into shared
getBootstrapContent() helper
- Cleaner single-implementation approach (removed fallback pattern)
v3.5.0 (2025-11-23)
Added
- OpenCode Support: Native JavaScript plugin for OpenCode.ai
- Custom tools:
use_skill and find_skills
- Message insertion pattern for skill persistence across context compaction
- Automatic context injection via chat.message hook
- Auto re-injection on session.compacted events
- Three-tier skill priority: project > personal > superpowers
- Project-local skills support (
.opencode/skills/)
- Shared core module (
lib/skills-core.js) for code reuse with Codex
- Automated test suite with proper isolation (
tests/opencode/)
- Platform-specific documentation (
docs/README.opencode.md, docs/README.codex.md)
Changed
v3.4.1 (2025-10-31)
Improvements
- Optimized superpowers bootstrap to eliminate redundant skill execution. The
using-superpowers skill content is now provided directly in session context, with clear guidance to use the Skill tool only for other skills. This reduces overhead and prevents the confusing loop where agents would execute using-superpowers manually despite already having the content from session start.
v3.4.0 (2025-10-30)
Improvements
- Simplified
brainstorming skill to return to original conversational vision. Removed heavyweight 6-phase process with formal checklists in favor of natural dialogue: ask questions one at a time, then present design in 200-300 word sections with validation. Keeps documentation and implementation handoff features.
v3.3.1 (2025-10-28)
Improvements
- Updated
brainstorming skill to require autonomous recon before questioning, encourage recommendation-driven decisions, and prevent agents from delegating prioritization back to humans.
- Applied writing clarity improvements to
brainstorming skill following Strunk's "Elements of Style" principles (omitted needless words, converted negative to positive form, improved parallel construction).
Bug Fixes
- Clarified
writing-skills guidance so it points to the correct agent-specific personal skill directories (~/.claude/skills for Claude Code, ~/.codex/skills for Codex).
v3.3.0 (2025-10-28)
New Features
Experimental Codex Support
- Added unified
superpowers-codex script with bootstrap/use-skill/find-skills commands
- Cross-platform Node.js implementation (works on Windows, macOS, Linux)
- Namespaced skills:
superpowers:skill-name for superpowers skills, skill-name for personal
- Personal skills override superpowers skills when names match
- Clean skill display: shows name/description without raw frontmatter
- Helpful context: shows supporting files directory for each skill
- Tool mapping for Codex: TodoWrite→update_plan, subagents→manual fallback, etc.
- Bootstrap integration with minimal AGENTS.md for automatic startup
- Complete installation guide and bootstrap instructions specific to Codex
Key differences from Claude Code integration:
- Single unified script instead of separate tools
- Tool substitution system for Codex-specific equivalents
- Simplified subagent handling (manual work instead of delegation)
- Updated terminology: "Superpowers skills" instead of "Core skills"
Files Added
.codex/INSTALL.md - Installation guide for Codex users.codex/superpowers-bootstrap.md - Bootstrap instructions with Codex adaptations.codex/superpowers-codex - Unified Node.js executable with all functionality
Note: Codex support is experimental. The integration provides core superpowers functionality but may require refinement based on user feedback.
v3.2.3 (2025-10-23)
Improvements
Updated using-superpowers skill to use Skill tool instead of Read tool
- Changed skill invocation instructions from Read tool to Skill tool
- Updated description: "using Read tool" → "using Skill tool"
- Updated step 3: "Use the Read tool" → "Use the Skill tool to read and run"
- Updated rationalization list: "Read the current version" → "Run the current version"
The Skill tool is the proper mechanism for invoking skills in Claude Code. This update corrects the bootstrap instructions to guide agents toward the correct tool.
Files Changed
- Updated:
skills/using-superpowers/SKILL.md - Changed tool references from Read to Skill
v3.2.2 (2025-10-21)
Improvements
Strengthened using-superpowers skill against agent rationalization
- Added EXTREMELY-IMPORTANT block with absolute language about mandatory skill checking
- "If even 1% chance a skill applies, you MUST read it"
- "You do not have a choice. You cannot rationalize your way out."
- Added MANDATORY FIRST RESPONSE PROTOCOL checklist
- 5-step process agents must complete before any response
- Explicit "responding without this = failure" consequence
- Added Common Rationalizations section with 8 specific evasion patterns
- "This is just a simple question" → WRONG
- "I can check files quickly" → WRONG
- "Let me gather information first" → WRONG
- Plus 5 more common patterns observed in agent behavior
These changes address observed agent behavior where they rationalize around skill usage despite clear instructions. The forceful language and pre-emptive counter-arguments aim to make non-compliance harder.
Files Changed
- Updated:
skills/using-superpowers/SKILL.md - Added three layers of enforcement to prevent skill-skipping rationalization
v3.2.1 (2025-10-20)
New Features
Code reviewer agent now included in plugin
- Added
superpowers:code-reviewer agent to plugin's agents/ directory
- Agent provides systematic code review against plans and coding standards

- Updated:
skills/subagent-driven-development/SKILL.md - References to superpowers:code-reviewer
v3.2.0 (2025-10-18)
New Features
Design documentation in brainstorming workflow
- Added Phase 4: Design Documentation to brainstorming skill
- Design documents now written to
docs/plans/YYYY-MM-DD-<topic>-design.md before implementation
- Restores functionality from original brainstorming command that was lost during skill conversion
- Documents written before worktree setup and implementation planning
- Tested with subagent to verify compliance under time pressure
Breaking Changes
Skill reference namespace standardization
- All internal skill references now use
superpowers: namespace prefix
- Updated format:
superpowers:test-driven-development (previously just test-driven-development)
- Affects all REQUIRED SUB-SKILL, RECOMMENDED SUB-SKILL, and REQUIRED BACKGROUND references
- Aligns with how skills are invoked using the Skill tool
- Files updated: brainstorming, executing-plans, subagent-driven-development, systematic-debugging, testing-skills-with-subagents, writing-plans, writing-skills
Improvements
Design vs implementation plan naming
- Design documents use
-design.md suffix to prevent filename collisions
- Implementation plans continue using existing
YYYY-MM-DD-<feature-name>.md format
- Both stored in
docs/plans/ directory with clear naming distinction
v3.1.1 (2025-10-17)
Bug Fixes
- Fixed command syntax in README (#44) - Updated all command references to use correct namespaced syntax (
/superpowers:brainstorm instead of /brainstorm). Plugin-provided commands are automatically namespaced by Claude Code to avoid conflicts between plugins.
v3.1.0 (2025-10-17)
Breaking Changes
Skill names standardized to lowercase
- All skill frontmatter
name: fields now use lowercase kebab-case matching directory names
- Examples:
brainstorming, test-driven-development, using-git-worktrees
- All skill announcements and cross-references updated to lowercase format
- This ensures consistent naming across directory names, frontmatter, and documentation
New Features
Enhanced brainstorming skill
- Added Quick Reference table showing phases, activities, and tool usage
- Added copyable workflow checklist for tracking progress
- Added decision flowchart for when to revisit earlier phases

- Added
skills/writing-skills/anthropic-best-practices.md - Official Anthropic skill authoring guide
- Referenced in writing-skills SKILL.md for comprehensive guidance
- Provides patterns for progressive disclosure, workflows, and evaluation
Improvements
Skill cross-reference clarity
- All skill references now use explicit requirement markers:
**REQUIRED BACKGROUND:** - Prerequisites you must understand**REQUIRED SUB-SKILL:** - Skills that must be used in workflow**Complementary skills:** - Optional but helpful related skills
- Removed old path format (
skills/collaboration/X → just X)
- Updated Integration sections with categorized relationships (Required vs Complementary)
- Updated cross-reference documentation with best practices
Alignment with Anthropic best practices
- Fixed description grammar and voice (fully third-person)
- Added Quick Reference tables for scanning
- Added workflow checklists Claude can copy and track
- Appropriate use of flowcharts for non-obvious decision points
- Improved scannable table formats
- All skills well under 500-line recommendation
Bug Fixes
- Re-added missing command redirects - Restored
commands/brainstorm.md and commands/write-plan.md that were accidentally removed in v3.0 migration
- Fixed
defense-in-depth name mismatch (was Defense-in-Depth-Validation)
- Fixed
receiving-code-review name mismatch (was Code-Review-Reception)
- Fixed
commands/brainstorm.md reference to correct skill name
- Removed references to non-existent related skills
Documentation
writing-skills improvements
- Updated cross-referencing guidance with explicit requirement markers
- Added reference to Anthropic's official best practices
- Improved examples showing proper skill reference format
v3.0.1 (2025-10-16)
Changes
We now use Anthropic's first-party skills system!
v2.0.2 (2025-10-12)
Bug Fixes
- Fixed false warning when local skills repo is ahead of upstream - The initialization script was incorrectly warning "New skills available from upstream" when the local repository had commits ahead of upstream. The logic now correctly distinguishes between three git states: local behind (should update), local ahead (no warning), and diverged (should warn).
v2.0.1 (2025-10-12)
Bug Fixes
- Fixed session-start hook execution in plugin context (#8, PR #9) - The hook was failing silently with "Plugin hook error" preventing skills context from loading. Fixed by:
- Using
${BASH_SOURCE[0]:-$0} fallback when BASH_SOURCE is unbound in Claude Code's execution context
- Adding
|| true to handle empty grep results gracefully when filtering status flags
Superpowers v2.0.0 Release Notes
Overview
Superpowers v2.0 makes skills more accessible, maintainable, and community-driven through a major architectural shift.
The headline change is skills repository separation: all skills, scripts, and documentation have moved from the plugin into a dedicated repository (obra/superpowers-skills). This transforms superpowers from a monolithic plugin into a lightweight shim that manages a local clone of the skills repository. Skills auto-update on session start. Users fork and contribute improvements via standard git workflows. The skills library versions independently from the plugin.
Beyond infrastructure, this release adds nine new skills focused on problem-solving, research, and architecture. We rewrote the core using-skills documentation with imperative tone and clearer structure, making it easier for Claude to understand when and how to use skills. find-skills now outputs paths you can paste directly into the Read tool, eliminating friction in the skills discovery workflow.
Users experience seamless operation: the plugin handles cloning, forking, and updating automatically. Contributors find the new architecture makes improving and sharing skills trivial. This release lays the foundation for skills to evolve rapidly as a community resource.
Breaking Changes
Skills Repository Separation
The biggest change: Skills no longer live in the plugin. They've been moved to a separate repository at obra/superpowers-skills.
What this means for you:
- First install: Plugin automatically clones skills to
~/.config/superpowers/skills/
- Forking: During setup, you'll be offered the option to fork the skills repo (if
gh is installed)
- Updates: Skills auto-update on session start (fast-forward when possible)
- Contributing: Work on branches, commit locally, submit PRs to upstream
- No more shadowing: Old two-tier system (personal/core) replaced with single-repo branch workflow
Migration:
If you have an existing installation:
- Your old
~/.config/superpowers/.git will be backed up to ~/.config/superpowers/.git.bak
- Old skills will be backed up to
~/.config/superpowers/skills.bak
- Fresh clone of obra/superpowers-skills will be created at
~/.config/superpowers/skills/
Removed Features
- Personal superpowers overlay system - Replaced with git branch workflow
- setup-personal-superpowers hook - Replaced by initialize-skills.sh
