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

Firefox CI Test Coverage by Platform

Use query.py first; it reads snapshots from assets/.

python3 ${CLAUDE_SKILL_DIR}/scripts/query.py  [args]

USE FOR:

Tier lookup, skip rates, coverage gaps, pool comparisons, green-up planning, platform retirement, and suite coverage analysis.

DO NOT USE FOR:

Live Taskcluster job status, try pushes, or refreshing stale snapshots unless the user asks.

Commands

Use summary, suite , platform , os , risk, skipped-everywhere, compare , or search .

Examples

"What's tier 1 on Windows 11?" Run platform windows11 or os windows.
"Tell me about xpcshell." Run suite xpcshell.
"Riskiest coverage gaps?" Run risk.
"Can we retire this pool?" Run compare .

Tier Model

Tier precedence: variant overrides, kind YAML tier settings, then the handle_tier() platform default. The same suite can have different tiers by platform.

Data Freshness

Check each snapshot's snapshot_date before migration or green-up decisions. Refresh stale data with [references/refresh.md](references/refresh.md).

Troubleshooting

Missing snapshots: confirm assets/tier_matrix.json, assets/tier_skip_crossref.json, and assets/skip_totals.json.
Stale data: refresh before release or pool-retirement decisions.
No match: run search for the canonical name.
Refresh import errors: install PyYAML, then rerun scripts/refresh.py.
