Preview Execution monitoring

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.

About

Cross-Agent Install Smoke

Validate additive skills sync without mutating live harness installs.

Scope: Install smoke only. Do not run live apply installs unless the maintainer explicitly requests it.

Dispatch

| $ARGUMENTS | Action | |------------|--------| | Empty / phase1 / dry-run | Run phase 1 dry-run JSON assertions | | phase2 / local / smoke | Run phase 2 temp-HOME smoke (requires INSTALL_SMOKE=1) | | all | Run phase 1, then phase 2 when gated | | help | Show phases, gates, and example commands |

Phase 1 — Dry-Run JSON

Run the deterministic checker from the repo root:

uv run python skills/cross-agent-install-smoke/scripts/dry_run.py

Phase 1 executes the repo skills-sync dry-run command and asserts:

  • top-level keys: ok, mode, inventory_count, include_installed, agents
  • mode is dry-run
  • each agent row includes agent plus list fields missing, already_present, unresolved, skipped

Pass criteria: script exits 0 and prints a JSON summary to stdout.

Phase 2 — Temp-HOME Smoke

Phase 2 is opt-in and mutates only a temporary home directory.

INSTALL_SMOKE=1 uv run python skills/cross-agent-install-smoke/scripts/local_smoke.py

The script:

  1. Refuses to run unless INSTALL_SMOKE=1
  2. Creates an isolated HOME under a temp directory
  3. Runs the repo validation command against the repo
  4. Runs a single-harness skills-sync dry-run JSON probe
  5. Cleans up the temp home

Never point phase 2 at a production home directory.

Validation Contract

uv run python skills/cross-agent-install-smoke/scripts/check.py
INSTALL_SMOKE=1 uv run python skills/cross-agent-install-smoke/scripts/check.py

Completion criteria:

  1. Phase 1 (dry_run.py) exits 0 in CI and local maintainer runs.
  2. Phase 2 runs only when INSTALL_SMOKE=1 is set.
  3. scripts/check.py exits 0 for the selected phase gates.

Critical Rules

  1. Default to dry-run; never apply live installs from this skill.
  2. Treat skills sync JSON as evidence, not authority over repo policy.
  3. Run phase 1 before recommending any cross-harness install reconciliation.
  4. Gate phase 2 behind INSTALL_SMOKE=1 and a disposable temp HOME.
  5. Report harness-specific inventory errors without masking top-level ok: false.
