Quality

Content

75%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.

The body is a tight, well-structured debugging overview that points to the right artifacts and routes to frb-fix-ci before deep work. It is concise and actionable, with the main gap being the absence of explicit validate/retry feedback loops for the diagnostic steps.

Suggestions

Turn the quick-diagnostics section into an explicit loop: inspect the dump -> form a hypothesis -> re-run with RUST_LOG=debug -> confirm the root cause before proceeding to internals.

Add a brief validation checkpoint after dumping IRs (e.g., what a correct vs. corrupted IR/spec looks like) so Claude can confirm findings before going deeper.

Specify what to do when the dump directory is empty or the codegen command fails to produce one, since that is a common failure mode for this skill.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, giving concrete paths and commands without explaining FRB fundamentals; only the opening remote-testing note and the trailing '...' add minor slack.

4 / 5

Actionability

Provides concrete, executable guidance such as `RUST_LOG=debug flutter_rust_bridge_codegen ...` and the `rust/target/frb_dump/` path, though the dump section lists what to inspect without showing how to act on findings.

4 / 5

Workflow Clarity

There is a clear triage sequence (quick diagnostics -> docs -> route to frb-fix-ci first) with an explicit MUST-gate before deep debugging, but the diagnostic loop itself lacks explicit validate/fix/retry checkpoints.

4 / 5

Progressive Disclosure

Well-organized single-level references to repo docs (`website/docs/...`) and related skills are clearly signaled with 'see:' and 'Related Skills', and the short body is appropriately split into sections with no nested references.

Description

70%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.

The description is concise, third-person, and has a strong explicit 'Use when...' trigger clause with natural debugging vocabulary. Its main weakness is that the 'what' is conveyed as triggering situations rather than concrete capabilities the skill performs.

Suggestions

Lead with a concrete verb phrase stating what the skill does (e.g., 'Diagnoses and inspects flutter_rust_bridge generated code...') before the 'Use when' clause so the 'what' is explicit rather than implied.

Add one or two natural synonyms a user might say (e.g., 'rust bindings', 'codegen errors') to broaden trigger coverage.

Disambiguate from frb-fix-ci directly in the description (e.g., note it is for deep FRB-internal diagnosis after CI-propagation causes are ruled out).

DimensionReasoningScore

Specificity

Names the FRB/generated-code domain and a few concrete situations ("generated code looks wrong", "code generation fails", "understand FRB internals"), but these are trigger situations rather than a list of concrete capabilities the skill performs.

3 / 5

Completeness

Explicit "Use when..." clause answers the 'when' clearly and concretely, while the 'what' (debugging generated code / understanding FRB internals) is present but somewhat implicit rather than crisply enumerated.

4 / 5

Trigger Term Quality

"generated code looks wrong", "code generation fails", and "FRB internals" are natural phrases a user would say when debugging; coverage is good though a few synonyms/variants are missing.

4 / 5

Distinctiveness Conflict Risk

FRB is a clear, narrow niche with distinct triggers and minimal conflict risk, though it overlaps slightly with the related frb-fix-ci skill mentioned in the body.
