crash-analytics

When the user wants to monitor, triage, or reduce their app's crash rate — including setting up Crashlytics, prioritizing which crashes to fix first, interpreting crash data, and understanding how crashes affect App Store ranking. Use when the user mentions "crash", "crashlytics", "crash rate", "ANR", "app not responding", "crash-free sessions", "crash-free users", "symbolication", "stability", "firebase crashes", "app crashing", or "crash report". For overall analytics setup, see app-analytics.

Quality

Content

81%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-built, highly actionable skill body: concrete code and commands, explicit thresholds, and genuine feedback loops (velocity alerts, pause-rollout rule, failing-test-first). Weaknesses are minor — light redundancy with the description, a placeholder dependency version, and a single-file structure that inlines platform setup details a leaner SKILL.md would split into references.

Suggestions

Replace the placeholder '18.x.x' in the Android dependency with either a concrete pinned version or a plain-English note to check the latest version, and add the one-line Podfile/SPM install step for iOS so both setup snippets are copy-paste ready.

Trim the redundant opening line and consolidate the App Store ranking claims into one place (either the 'Why Crash Rate Is an ASO Signal' section or the Related Skills notes) instead of repeating them.

Consider moving the per-platform Crashlytics setup and symbolication detail into a references/ file, keeping SKILL.md as a lean triage-and-monitoring overview with one-level-deep pointers.

DimensionReasoningScore

Conciseness

The body is dense and table-driven with almost no padding, but there are minor instances that could be trimmed: the opening line restates the description, and the 'Why Crash Rate Is an ASO Signal' bullets partially duplicate the Related Skills section's claims. Matches 'Efficient; minor instances of over-explanation that could be trimmed' rather than the fully lean anchor 5.

4 / 5

Actionability

Guidance is mostly executable: real Swift/Kotlin snippets, a copy-paste bash command for dSYM upload, exact menu paths, thresholds, and phased-release percentages. It falls short of anchor 5 due to minor gaps — the Android dependency uses a placeholder version ('com.google.firebase:firebase-crashlytics:18.x.x') and no Podfile/SPM install snippet is shown for iOS, so the setup code is not fully copy-paste ready.

4 / 5

Workflow Clarity

Multi-step processes are clearly sequenced with explicit checkpoints and feedback loops: dashboard triage steps 1–4, debug steps including 'Write a failing test before fixing', and the release strategy's 'Monitor Crashlytics for 24 hours at each phase. If crash rate increases >0.2%, pause rollout.' Matches 'Clear sequence with explicit validation steps; feedback loops for error recovery'.

5 / 5

Progressive Disclosure

The single file is well-organized with clear section headers, tables, and a Related Skills section for navigation, and no bundle files exist to misplace. However, at ~180 lines with per-platform setup code and release-strategy detail inlined, some content could be split into reference files, so it sits at 'Good structure; most content is appropriately placed; minor organization gaps' rather than the cleanly split anchor 5.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete capability list, explicit 'Use when' trigger clause with natural synonyms, and clear boundary disambiguation against the broader app-analytics skill. All dimensions sit at the top anchors with no fluff or over-claims.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'monitor, triage, or reduce their app's crash rate', 'setting up Crashlytics', 'prioritizing which crashes to fix first', 'interpreting crash data', and 'understanding how crashes affect App Store ranking' — giving comprehensive coverage of the skill's capabilities. It matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and is not score 4 because there are no meaningful gaps in the action coverage.

5 / 5

Completeness

It explicitly answers both 'what' (monitor/triage/reduce crash rate, set up Crashlytics, prioritize fixes, interpret crash data, understand App Store ranking impact) and 'when' ('Use when the user mentions "crash", "crashlytics", ...'). This mirrors the anchor-5 example structure exactly; it is not score 4 because the 'when' clause is fully explicit rather than vague.

5 / 5

Trigger Term Quality

The trigger list is comprehensive and natural: 'crash', 'crashlytics', 'crash rate', 'ANR', 'app not responding', 'crash-free sessions', 'crash-free users', 'symbolication', 'stability', 'firebase crashes', 'app crashing', and 'crash report'. It includes synonyms users would actually say (e.g., 'app not responding' for ANR, 'app crashing'), matching the anchor 'Comprehensive coverage of natural terms including synonyms'.

5 / 5

Distinctiveness Conflict Risk

It carves out a clear niche (crash analytics) with distinct, domain-specific triggers and explicitly disambiguates the boundary case — 'For overall analytics setup, see app-analytics' — minimizing conflict with the sibling analytics skill. Matches 'Clear niche with distinct triggers; minimal conflict risk'.
