Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

perf-profiler
Run profiling tools and capture hotspots with evidence.
Follow docs/perf-requirements.md as the canonical contract.
Parse Arguments
const args = '$ARGUMENTS'.split(' ').filter(Boolean);
const tool = args[0] || '';
const command = args.slice(1).join(' ');Required Rules
- Verify debug symbols before profiling.
- Capture file:line for hotspots.
- Provide flame graph or equivalent output when possible.
Output Format
tool:
command:
hotspots:
- file:line - reason
artifacts:
- Constraints
- No profiling without a clear scenario.
- Keep outputs minimal and evidence-backed.
