mecatl is a streaming agentic loop. Its time is dominated by off-CPU waiting (on the model and on tool I/O), so the usual "run a CPU profile first" instinct measures the wrong thing. Diagnose by reading cheap numeric state first, and reach for the perturbing CPU tools only with a hypothesis to confirm.
Perf Mcp Interpretation is a community-contributed Claude Code skill in the ai-tooling sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/perf-mcp-interpretation/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when connected to the mecatl perf MCP server (the perf:// resources or the query_metric / top_cpu_functions / capture_cpu_profile / top_allocations / list_slow_turns / capture_flight_recorder tools) and investigating why mecatl is slow, leaking, or growing. Covers tool routing/cost, reading pprof rankings and runtime metrics, and the leak/contention/GC signatures.
The Perf Mcp Interpretation Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 206,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
