dart-tooling

dart-tooling is a skill for Claude Code, Codex from HoangNguyen0403/agent-skills-standard. It costs 62 tokens per session (496 once invoked), scanned A, original, MIT.

Standards for Dart tooling such as static analysis, formatting, lint rules, code generation, and CI checks. Static analysis examines code for likely mistakes before it runs.

In plain words
What is it for?
Use it when changing analysis_options.yaml, build_runner, formatting, DCM, lefthook, or Dart analysis and formatting checks in CI.
Why use it?
They keep automated checks consistent and prevent formatting, generated-file conflicts, or analysis failures from reaching the main codebase.

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

dart-tooling 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 9d 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

Tooling & CI

Priority: P1 (HIGH)

Implementation Guidelines

  • Linter: Use analysis_options.yaml. Enforce always_use_package_imports and require_trailing_commas.
  • Formatting: Use dart format . --line-length 80. Run on every commit.
  • DCM: Use dart_code_metrics for complexity checks (Max cyclomatic complexity: 15).
  • Build Runner: Always use --delete-conflicting-outputs with code generation.
  • CI Pipeline: All PRs MUST pass analyze, format, and test steps.
  • Imports: Group imports: dart:, package:, then relative.
  • Documentation: Use /// for public APIs. Link symbols using [Class].
  • Linting Commands:
  • flutter analyze --fatal-infos --fatal-warnings
  • dart run dart_code_metrics:metrics analyze lib
  • Pre-commit: Keep lefthook.yml in sync with analyze/format/metrics commands.

Code

# analysis_options.yaml
analyzer:
  errors:
    todo: ignore
    missing_required_param: error
linter:
  rules:
    - prefer_single_quotes
    - unawaited_futures

Anti-Patterns

  • No build_runner without --delete-conflicting-outputs: Causes stale generated file conflicts that break compilation.
  • No flutter build before flutter analyze: Analyze fast; always fail fast before building.
  • No ignore comment without explanation: Always annotate why lint ignore justified.
  • No skipping dart format in pre-commit: Unformatted code breaks CI; enforce via lefthook.yml.

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.

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.
