Quality

Content

77%

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 well-sequenced, actionable workflow with strong validation and feedback loops, but it is verbose with restated constraints and references a known_consumers.md file that is not present in the bundle.

Suggestions

Create resources/known_consumers.md (or remove the two links to it) so the referenced consumer list actually resolves.

Consolidate the 'do not commit downstream changes' constraint into one stated location instead of repeating it across the IMPORTANT block, Pathway B, and the cleanup section.

Tighten prose asides such as the 'Discovering Local Checkouts' sub-steps and the redundant restatements of transient-edit handling to reduce token cost.

DimensionReasoningScore

Conciseness

The body is operational but padded — the 'No Downstream Commits Allowed' constraint is restated three times (IMPORTANT block, Pathway B constraint, cleanup note) and several asides could be tightened, so it does not meet 'every token earns its place'.

2 / 3

Actionability

Concrete executable commands appear throughout — 'git status', 'dart test', 'flutter pub get', 'dart analyze --fatal-infos <path>', 'dart format .' — plus a copy-paste pubspec.yaml ref example, giving specific actionable guidance.

3 / 3

Workflow Clarity

A clear four-section sequence with explicit validation checkpoints ('verify all existing tests pass', 'dart analyze --fatal-infos', re-run migrated suite) and a feedback loop in Section 3 (failure -> diagnose -> human decision -> Pathway A/B) for a risky operation.

3 / 3

Progressive Disclosure

Sections are well-organized, but the body links to resources/known_consumers.md twice and that file (and resources/ directory) does not exist, so the navigation is broken and all content sits inline in one file.

Description

100%

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 third-person, concrete, and complete with an explicit 'Use when...' trigger covering several natural invocation phrases. It carves out a distinct niche and avoids over-claiming.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Validates an in-progress PR or feature branch', 'assessing breaking changes', 'testing migrations against the changelog', 'determining necessary backwards compatibility shims' — rather than vague language.

3 / 3

Completeness

Explicitly answers both what ('Validates an in-progress PR... against known downstream ecosystem consumers') and when ('Use when assessing breaking changes...'), matching the anchor with an explicit trigger clause.

3 / 3

Trigger Term Quality

The 'Use when...' clause covers natural trigger phrases a developer would say — 'breaking changes', 'PR evaluation', 'migrations', 'changelog', 'backwards compatibility shims' — with good variation.

3 / 3

Distinctiveness Conflict Risk

The niche is sharply defined — validating dart_skills_lint against downstream consumers — with triggers unlikely to fire for unrelated skills.
