Post-v1.18.1 follow-up. Adds the /investigate-metrickit MCP prompt (the 7th, completing the prompt surface for the v1.18 MetricKit lane) and syncs the README prompt count which had drifted (stale at 5, actual 7 including /summarize-trace and the new MetricKit prompt). No tool API changes. 757 -> 758 tests (+1).
Added
/investigate-metrickitMCP prompt (7th prompt). Bespoke render (not playbook-backed). Takes apayloadPathargument and produces a ready-to-execute brief: 4 read-priority sections (crashCluster, hangHotspots, cpuExceptions, diskWriteExceptions),suggestedNextCallschain hints intofindCycles/analyzeHangs, and explicit constraints (no symbolication, no direct fix from raw.mxdiagnostic,payloadCount: 0is a valid state). Surfaces in Claude Code as/investigate-metrickit. Prompt count goes from 6 to 7. Asserted viabespoke = ["summarize-trace", "investigate-metrickit"]filter in the playbook-backed coverage test.
Changed
- README prompt count synced. The README listed 5 prompts (stale snapshot from v1.16) when actual count is 7. Updated to enumerate all 7 prompts, including
/summarize-trace(v1.17) and the new/investigate-metrickit.
