Quality

Content

65%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-structured, lean index-style skill that routes platform-specific detail to real reference files at one level of depth. Its weaknesses are in the body itself: no executable commands or verification steps, so a reader cannot confirm a working setup from SKILL.md alone.

Suggestions

Include the concrete MCP server install command (e.g., the `npx -y firebase-tools@latest` invocation from the compatibility field) directly in the Prerequisites section so the body is self-sufficient for data access setup.

Add an explicit validation step after SDK setup, such as triggering a test crash and confirming the report arrives in the Crashlytics dashboard, so the workflow has a verification checkpoint.

Trim the redundant lead-in sentences ('This skill provides a complete guide...' and 'The SDK provides a number of features...') to tighten token efficiency.

DimensionReasoningScore

Conciseness

The body is efficient overall, but two lead-in sentences ('This skill provides a complete guide for getting started...' and 'The SDK provides a number of features to make crash reports more actionable') add little and could be trimmed, matching the 'minor instances of over-explanation' anchor rather than the fully lean level 5.

4 / 5

Actionability

The body gives concrete direction (prerequisites of a Firebase project and app, per-platform reference links, external doc URLs) but contains no executable commands or code itself — even the MCP server install is only named, with its command deferred elsewhere — matching the 'some concrete guidance but incomplete' anchor.

3 / 5

Workflow Clarity

The Prerequisites → SDK Setup → SDK Usage section order implies a sequence, but the steps are not explicitly ordered and there is no verification checkpoint (e.g., forcing a test crash and confirming it appears in the dashboard/MCP), fitting the 'sequence present but checkpoints missing' anchor.

3 / 5

Progressive Disclosure

The body is a concise overview with clearly signaled one-level-deep references to real, substantial bundle files ([android_setup.md](references/android_setup.md) and [ios_setup.md](references/ios_setup.md)) plus one-level external doc links, matching the top anchor for clear navigation and appropriate content split.

Description

82%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: it names a precise product niche, states both what it covers and an explicit 'Use this skill when...' trigger with three concrete conditions. The only weakness is that the capability list is brief (provisioning and SDK usage) and a few natural synonyms for crash reporting are absent.

DimensionReasoningScore

Specificity

The description names the domain precisely ('Comprehensive guide for Firebase Crashlytics, including provisioning and SDK usage') and lists two concrete action areas (provisioning, SDK usage), matching the anchor for 1-2 concrete actions rather than the 'several specific actions' of level 4; 'Comprehensive guide' is mild fluff.

3 / 5

Completeness

It clearly states what the skill does ('guide for Firebase Crashlytics, including provisioning and SDK usage') and explicitly when to use it ('Use this skill when the user needs help setting up Crashlytics, adding crash reporting, or using the Crashlytics SDK') with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Triggers like 'setting up Crashlytics', 'adding crash reporting', and 'using the Crashlytics SDK' are natural phrases users would say and include the exact product name, but common variations such as 'crash logs', 'app crashes', 'stack traces', or 'stability' are missing, so it falls short of level 5.

4 / 5

Distinctiveness Conflict Risk

'Firebase Crashlytics' and 'Crashlytics SDK' are specific product identifiers giving the skill a clear niche with distinct triggers and minimal overlap risk, aside from very slight adjacency to general Firebase skills.
