What it does

Signals Lint is an agent skill from rodydavis/signals.dart. Standardized compiler diagnostics, static analysis lints, and automated IDE quick-fixes.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `CONTEXT.md`).

It sits in Development, covering Linting and formatting, Static analysis and SAST and Cross-platform mobile apps. It works with Flutter. The repository describes itself as: Reactive programming made simple for Dart and Flutter. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Linting and formatting
  • Tasks that involve Static analysis and SAST
  • Tasks that involve Cross-platform mobile apps

Example prompts

  • “/signals-lint”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. signals_avoid_create_in_build_method
  2. signals_avoid_deprecated_watch_extension
  3. signals_avoid_deprecated_signals_mixin
  4. signals_prefer_named_builder
  5. signals_prefer_unified_options

What it can do on your machine

Read from SKILL.md and the folder at commit 81d64e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Signals Lint loads about 712 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~712

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

signals_lint Tooling & Rules

This skill covers working with static code analysis, custom compiler warning diagnostics, and automated quick-fixes in the signals.dart ecosystem.


🚀 Activation & Setup

Ensure the plugin is active in your project to enable real-time IDE diagnostics and fixes:

yaml
# pubspec.yaml
dev_dependencies:
  custom_lint: ^0.8.1
  signals_lint: ^7.0.0
yaml
# analysis_options.yaml
analyzer:
  plugins:
    - custom_lint

🛡️ Lint Rules Reference

1. signals_avoid_create_in_build_method

Flags instances where a signal or computed variable is created inside a Flutter build method.

  • Problem: Creating state during build causes state to reset on every rebuild.
  • Solution: Move the creation to the class fields or initialize inside a state lifecycle hook.

2. signals_avoid_deprecated_watch_extension

Flags uses of deprecated BuildContext.watch() and BuildContext.unwatch() extensions.

  • Problem: Watch extensions can cause broad stateful widget lifecycle overhead.
  • Solution: Use localized SignalBuilder or inherit from SignalWidget/SignalStatefulWidget.

3. signals_avoid_deprecated_signals_mixin

Flags usage of deprecated with SignalsMixin mixins on StatefulWidget states.

  • Problem: Inherits stateful widget tracking hooks unnecessarily.
  • Solution: Inherit from SignalStatefulWidget instead.

4. signals_prefer_named_builder

Enforces named builder: callbacks in SignalBuilder and Watch elements instead of positional arguments.

  • Reason: Guarantees standard API parameters and readability.

5. signals_prefer_unified_options

Flags direct creator configuration arguments (e.g. autoDispose: true).

  • Solution: Bundle configuration properties under unified options classes (e.g., options: SignalOptions(autoDispose: true)).

💡 Automated IDE Code Assists (Quick-fixes)

Place your cursor on the relevant class name or widget instantiation inside your IDE to reveal these automatic assists via the quick-fix menu (Cmd+. or Alt+Enter):

  1. WrapWithSignalBuilder: Wraps any widget expression inside SignalBuilder(builder: (context) => ...).
  2. ConvertStatelessToSignalWidget: Refactors a standard StatelessWidget into a SignalWidget instantly.
  3. ConvertStatefulToSignalStatefulWidget: Refactors a standard StatefulWidget to a SignalStatefulWidget.
  4. MigrateSignalsMixinToSignalStatefulWidget: Strips the legacy SignalsMixin and converts the class structure to SignalStatefulWidget.
  5. MigrateWatchToSignalBuilder: Converts legacy Watch(...) instances into clean SignalBuilder widgets.
