Find agent skills by outcome

- Simulate edge-case user inputs mentally: empty queries

ambiguous phrasing

PromptBeginner5 minmarkdownQuality: 28

- Verify that test suites include concurrency stress tests

not just single-threaded happy-path coverage.

PromptBeginner5 minmarkdownQuality: 28

- Verify that every new variable is initialized before use on all code paths

including early returns and exception handlers.

- Check each branch condition for off-by-one

negation

- Start from the diff

not the entire codebase; focus analysis on changed lines and their immediate callers and callees.

- Identify zero-downtime deployment risks from schema changes

cache invalidation

- Verify health check endpoints accurately reflect service readiness

not just process liveness.

Data

- Check for startup ordering dependencies between services

databases

- Check for data validation at trust boundaries: API inputs

file uploads

Data

- Assess data serialization and deserialization for version skew

missing fields

- Validate idempotency of operations that may be retried by queues

load balancers

- Confirm that timeout

retry

- Assess infrastructure-as-code changes for resource sizing

scaling policy

- Review every modified function for introduced null dereference

type mismatch

- Error message information leakage exposing stack traces

internal paths

- Missing retry logic for transient failures in network calls

distributed locks

- Silent exception swallowing in catch blocks that neither log

re-throw

- Missing fallback behavior when an agent's required tool

memory store

- Memory leaks from accumulated event listeners

growing caches without eviction

Data

- Data races on shared mutable state without locks

atomics

- Comparison errors: using identity instead of equality

floating-point epsilon failures

- File descriptor leaks from unclosed streams

sockets

- Regular expression defects: catastrophic backtracking

greedy vs. lazy mismatch

- Arithmetic overflow

underflow
