Firefox CI Test Coverage By Platform

Firefox CI Test Coverage by Platform

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

python3 ${CLAUDE_SKILL_DIR}/scripts/query.py <command> [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 <name>, platform <name>, os <linux|windows|macos|android>, risk, skipped-everywhere, compare <platform1> <platform2>, or search <term>.

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 <old> <new>.

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.

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 <term> for the canonical name.
• Refresh import errors: install PyYAML, then rerun scripts/refresh.py.
