Diagnose CI failures and stabilize pipelines. Use when a mid-level developer needs to resolve flaky or failing builds.
zig-0.16
by zigcc
Notes for porting code to Zig 0.16-dev (std.Io era). Use this when fixing 0.15-era code that fails on 0.16 master/dev.
defense-in-depth
by NickCrew
Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible
interaction-design
by NickCrew
User flow design, micro-interactions, and interface behavior patterns with state management for all interaction conditions. Use when designing natural interactions, feedback systems, or handling error states.
dispatching-parallel-agents
by NickCrew
Use when facing 3+ independent failures that can be investigated without shared state or dependencies - dispatches multiple Claude agents to investigate and fix independent problems concurrently
incident-response
by NickCrew
Incident triage, cascade prevention, and postmortem methodology. Use when handling production incidents, designing resilience patterns, or conducting chaos engineering exercises.
condition-based-waiting
by NickCrew
Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses
api-error-taxonomy
by proflead
Define consistent API error codes and responses. Use when a mid-level developer needs error standardization.
