- life-premortemmohitagw15856/pm-claude-skillsWrite the failure story of your year, relationship, move, or big life bet in advance — imagine it's a year later and it went wrong, tell that story vividly, then mine it for the real risks and the cheap things that would have prevented them. Use when someone says 'I'm about to make a big life change', 'what could go wrong with this', 'de-risk my year', or is committing to something large and irreversible. Produces the failure narrative, the extracted risk list with preventatives, and the early-warning signs to watch. The life-scale sibling of a project premortem.WritingNo warnings★ 1.5K↓ —
- red-green-proofalirezarezvani/claude-skillsTurns a suspected bug into a proven one. Verify the cause against reality before claiming it, write a test that FAILS on the current code, apply the fix, watch it pass — then revert the fix and confirm the test goes red again, because a test that passes both ways proves nothing. Invoked bare after a debugging conversation, it takes the target from context rather than asking. Use when fixing a bug, investigating an incident, hardening a flaky area, or when asked to "add tests that reveal the bug". Triggers on "/red-green-proof", "prove the bug", "red-green", "make the test fail first", "is that test load-bearing", "reveal the bug with a test".TestingNo warnings★ 29.2K↓ —

cache-efficiency
hoangsonww/Claude-Code-Agent-Monitor
From the author
Analyze prompt-cache effectiveness for Claude Code usage from the Agent Monitor dashboard — cache hit rate (total_cache_read / (total_cache_read + total_input)), cache_write vs cache_read reuse, cache-read vs cache-write spend, and the sessions with the poorest reuse. Pulls token totals from /api/analytics, per-session detail from /api/sessions, and dollar splits from /api/pricing/cost. Use when diagnosing cache spend or deciding whether prompt caching is paying off.
