Conciseness

Lean and dense with project-specific facts (project id, app id, fix SHAs, exact filter format); every line earns its place and it assumes Claude's competence rather than re-explaining Crashlytics concepts.

Actionability

Fully executable guidance — concrete MCP calls ('crashlytics_get_report' for topVersions with NO filter, topIssues filtered to the exact display name), 'gh release list' for versionCode mapping, and dispatch of the 'crash-investigator' agent in a single message with the exact fields to hand each.

Workflow Clarity

Clear four-step sequence (version context → top issues → parallel fan-out → verdict) with explicit validation checkpoints — 'map candidate versionCodes to releases via gh release list before picking' and 'Each investigator must verify the crashing versionCode against the fix's release before reporting known-fixed-residual' — guarding a batch fan-out operation.

Progressive Disclosure

Under 50 lines with no external references required and no bundle files present; the well-organized numbered sections give clear navigation, satisfying the simple-skill exception for progressive disclosure.

Specificity

Lists multiple concrete actions — 'establish the right version filter (topVersions first, then topIssues filtered to "X.Y.Z (versionCode)")', 'fan out one crash-investigator subagent per top issue in parallel', and 'return a distilled verdict table' — comprehensive coverage with no vague filler.

Completeness

Explicitly answers both what (triage crashes via version filter, parallel fan-out, verdict table) and when ('Use for "what's crashing", "triage Crashlytics", or "is build NNNN healthy" sweeps') with concrete trigger phrases.

Trigger Term Quality

Includes natural phrases a user would actually say — 'what's crashing', 'triage Crashlytics', 'is build NNNN healthy' — plus synonyms and a concrete negation trigger ('for a single known issue id, dispatch crash-investigator directly instead').

Distinctiveness Conflict Risk

Occupies a clear niche (Firebase Crashlytics triage for the Meshtastic-Android project) with distinct triggers and an explicit boundary against dispatching crash-investigator directly for single known issues, minimizing wrong-skill conflict.
