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.
How agent discovery & health will work →About
Purpose
Run unit tests, report failures with enough detail to debug, then (with approval) fix issues and re-run to confirm.
Arguments
--scope— Limit toapps/web,packages/shared, orall(default: all)--no-fix— Report only, don't offer to fix
Workflow
1. Run tests
# All tests
pnpm test
# With coverage (if configured)
pnpm test -- --coverage
# Scoped
pnpm -C apps/web test
pnpm -C packages/shared test2. Report results
Include:
- Pass/fail/skip counts
- Coverage summary (if available)
- Each failing test: file, test name, assertion diff or error
- If coverage not configured, note this and offer to set it up
3–4. Approval gate, fix and confirm
See /shared-review-workflow for approval gate protocol, fix constraints, and severity definitions.
