Dart Cleanup

🎯 Dart Cleanup & Refactoring Router

[!NOTE] Personal Environment Router: This skill is optimized for @kevmoo's local development environment and assumes specialized skills are checked out under ~/github/kevmoo/ and ~/github/dart-lang/. Other users should clone the required repositories or adapt the catalog paths in Skill Catalog to match their local layout.

Orchestrates specialized Dart workflows from local GitHub checkouts without pre-loading heavy individual skills into static prompt memory.

🛠️ Operating Protocol

1. Intent Evaluation & Confidence Matching (Strict Single-Skill Target)

When invoked with text (e.g. /dart-cleanup convert expect matchers to checks), evaluate the input against the Skill Catalog using this 3-tier confidence decision tree:

• Tier 1: Unambiguous Clear Match (High Confidence / 90%+ sure)
  • Exactly 1 skill in the catalog clearly maps to the requested transformation.
  • Action:
    1. Check for the target SKILL.md at its candidate path in ~/github/.
    2. If missing, output the Missing Checkout Safety Net.
    3. If present, call view_file on the target SKILL.md, hydrate its untruncated instructions into active context, and execute the refactoring immediately.
• Tier 2: Uncertain / Close Match (Medium Confidence)
  • A skill seems close or relevant, but there is ambiguity.
  • Action: Stop and ask the user for confirmation before hydrating:

    "I think you might mean <skill-name> (SKILL.md). Would you like me to load and run this workflow?"

• Tier 3: No Clear Match or Bare Invocation (Low Confidence / Empty Input)
  • No skill matches the prompt, or /dart-cleanup was invoked with no arguments.
  • Action: Output:

    "I couldn't find an unambiguous skill match for your request. Here is the catalog of available specialized Dart skills:" Render the categorized Skill Catalog with clickable file:// links so the user can choose.

2. Missing Checkout Safety Net

If a target SKILL.md is selected but missing from the local filesystem, output:

⚠️ Missing local checkout: Target skill <skill-name> was not found at ~/github/.... Please ensure https://github.com/<org>/<repo> is cloned into ~/github/.

📋 Skill Catalog & Path Priority

A. Refactoring & Code Quality

• dart-cognitive-complexity: Reduces cognitive complexity, nested loops, and deep conditionals via pattern matching & guard clauses. Includes a gated Tier 3 method-object reference for extreme cases.
  • Path: SKILL.md
• dart-undead: Audits, triages, and safely remediates unreachable and dead declarations in Dart and Flutter codebases using deterministic reachability analysis (pkg:undead).
  • Path: SKILL.md
• dart-dedupe: Detects, audits, and safely remediates structural code duplication across Dart and Flutter repositories using the standalone Dedupe engine (pkg:dedupe) and empirical test gating.
  • Path: SKILL.md
• dart-build-cli-app: CLI entrypoint structure, argument parsing, cross-platform scripts, exit codes.
  • Path: SKILL.md

B. Language Modernization & Formatting

• dart-best-practices: Effective Dart guidelines, class design, null safety, and general style.
  • Path: SKILL.md
• dart-modern-features: Records, pattern matching, switch expressions, extension types, class modifiers.
  • Path: SKILL.md
• dart-multiline-strings: Converts consecutive print statements & string concatenations into triple-quoted strings.
  • Path: SKILL.md
• dart-long-lines: Formats code to adhere to the 80-column line limit (lines_longer_than_80_chars).
  • Path: SKILL.md

C. Testing & Assertions

• dart-migrate-to-checks-package: Converts legacy expect(a, equals(b)) matchers to modern package:checks syntax (check(a).equals(b)).
  • Path: SKILL.md
• dart-use-pattern-matching: Refactors complex conditionals and destructuring to idiomatic Dart 3 pattern matching.
  • Path: SKILL.md
• dart-test-fundamentals: Core package:test practices, grouping, setUp/tearDown lifecycles, and dart_test.yaml.
  • Path: SKILL.md
• dart-matcher-best-practices: Best practices for legacy package:matcher assertions.
  • Path: SKILL.md
• dart-collect-coverage: Collecting coverage using package:coverage and creating LCOV reports.
  • Path: SKILL.md
