Use this skill when you need to set up validation for AI agent skills in a Dart project for the first time. Adds the linter as a dev_dependency, creates a configuration file, and generates a baseline for legacy repos.

What this skill does


# Setting up Skill Validation with dart_skills_lint

This skill covers **first-time wiring** of `dart_skills_lint` into a
repository. For ongoing use — running the linter, interpreting
output, and writing custom rules — see the
[`dart-skills-lint-validation`](../dart-skills-lint-validation/SKILL.md)
skill. For copy-pasteable CI workflow and pre-commit hook recipes,
see the [`Recipes` section of the README](../../README.md#recipes).

## Steps

1. **Add `dart_skills_lint` as a `dev_dependency`.** Prefer a git
   dependency (the package isn't on pub.dev yet):

   ```yaml
   dev_dependencies:
     dart_skills_lint:
       git:
         url: https://github.com/flutter/skills.git
         path: tool/dart_skills_lint
   ```

   **Isolate the dependency** in a `tool/` package when you can,
   instead of putting it on the root `pubspec.yaml` — keeps the
   linter's deps out of your runtime closure. If you must add it
   to multiple `pubspec.yaml` files, ensure the `ref:` (commit
   hash) is identical across all of them so resolution doesn't
   diverge.

2. **Create `dart_skills_lint.yaml`** at the repository root so both
   the CLI and any embedded test invocation share the same config:

   ```yaml
   dart_skills_lint:
     rules:
       check-relative-paths: error
       check-trailing-whitespace: error
     directories:
       - path: ".agents/skills"
   ```

   Rules enabled by default — `check-absolute-paths`,
   `valid-yaml-metadata`, `invalid-skill-name`,
   `description-too-long` — only need to be listed if you want to
   change their severity. See [`RULES.md`](../../RULES.md) for the
   full list.

3. **Generate a baseline** if you're integrating into a repository
   with pre-existing skills that have legacy violations you don't
   want to fix immediately:

   ```bash
   dart run dart_skills_lint:cli --skills-directory=.agents/skills --generate-baseline
   ```

   This writes the current set of failures into an ignore file so
   the next run exits clean. New violations introduced after the
   baseline still surface as errors.

4. **Wire it into CI.** Use the
   [GitHub Actions recipe](../../README.md#recipes) from the README
   verbatim, or follow the
   [pre-commit hook recipe](../../README.md#recipes) below it.

skill-development

Included

Comprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.

reprompter

Included

Transform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.

adaptive-compaction

Included

Adaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.

AI Agentsscripts

agent-skill-creator

Included

Create cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.

AI Agentsscripts

llm-wiki

Included

Use when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.

AI Agentsscripts

skill-master

Included

Agent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
