flutter-dart-code-review

A checklist-based review tool for Flutter and Dart code. Flutter is a framework for app interfaces, while Dart is the programming language used to write them; the review covers widgets, state management, performance, accessibility, security, and architecture.

In plain words
What is it for?
Use it to review Flutter or Dart code for widget practices, state handling, performance, accessibility, security, dependencies, navigation, error handling, localization, and testing gaps.
Why use it?
It helps find common quality, maintainability, and usability problems in Flutter applications. It also checks project structure and code-connection risks before the manual review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flutter-dart-code-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/supergraph:flutter-dart-code-review

Library-agnostic Flutter/Dart code review. Graph-first, then checklist.

Announce: "🐦 /supergraph:flutter-dart-code-review — reviewing Flutter/Dart code..."

Steps

1. Graph analysis (surface hotspots before manual review)

Use CBM_PROJECT: call get_architecture with hotspots, then validated hubs, cycles, complexity, cross-boundary, and test-gaps recipes. Apply the existing Flutter thresholds: build() over 80–100 lines, complexity limits, 10+ dependents, circular DI, unexpected layer coupling, and untested files.

Serena (optional — if available):

mcp__serena__get_diagnostics_for_file(<file>)      # type errors, null safety violations
mcp__serena__find_referencing_symbols(<symbol>)    # callers of changed public APIs
mcp__serena__find_implementations(<interface>)     # subclasses after interface change

Skip if Serena unavailable.

2. Manual checklist review

Work through CHECKLIST.md — 15 sections covering: General health · Dart pitfalls · Widgets · State management · Performance · Testing · Accessibility · Platform · Security · Dependencies · Navigation · Error handling · l10n · DI · Static analysis

Focus on areas flagged by step 1 first.

3. Report

## Flutter/Dart Review
- Graph hotspots: [list/none]
- Serena diagnostics: [issues/clean/skipped]
- Checklist: PASS | ISSUES (list critical items)
- Next: /supergraph:fix → /supergraph:verify

Rules

  • Run graph analysis before opening checklist — prioritize hotspots
  • Serena diagnostics catch null safety / type errors manual review misses
  • State management rules apply to ALL solutions (BLoC, Riverpod, GetX, MobX, Signals)
  • Full checklist in CHECKLIST.md
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
