Mandatory checks to run before completing any task that touches md files or dart code in this repository.
npx skills add https://github.com/flutter/agent-plugins --skill definition-of-done
Use this skill to ensure that all work meets the repository standards before declaring a task complete or requesting review.
Before stating that a task is complete, you MUST execute and pass the following checks:
dart format . to format files, or dart format --output=none --set-exit-if-changed . to check without modifying. Ensure all files are formatted correctly.dart analyze --fatal-infos and ensure there are zero issues (including info-level issues).dart run cognitive_complexity --fail-threshold 48 lib test and ensure there are zero issues. This checks for cognitive complexity.dart test and ensure all tests pass successfully.dart run dart_skills_lint -d .agents/skills to ensure they are valid.CHANGELOG.md.CHANGELOG.md untouched and output [x] Changelog: (N/A) <reason>.You MUST include a text list of all mandatory verification steps in your final response to the user. Use the exact following format:
[x] <Identifier>: <Explanation> if the step was completed.[ ] <Identifier>: <Skipped explanation> if the step was skipped or not applicable.CRITICAL: Do not just copy the full step description text. You MUST use the exact bolded Identifier from the Mandatory Verification Steps list above, followed by a colon and your short explanation.
Examples:
[x] Format: dart format success.[x] Analysis: Static clean (0 issues, dart analyze --fatal-infos).[ ] Skills: Skipped because dart_skills_lint is not installed.[x] Changelog: (N/A) Not necessary since we're updating internal eval fixtures.[x] Temporal: no added words.Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Automatically creates user-facing changelogs from git commits by analyzing commit history, categorizing changes, and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup

React Native and Expo best practices for building performant mobile apps. Use when building React Native components, optimizing list performance, implementing animations, or working with native modules. Triggers on tasks involving React Native, Expo, mobile performance, or native platform APIs.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Next.js best practices - file conventions, RSC boundaries, data patterns, async APIs, metadata, error handling, route handlers, image/font optimization, bundling
Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification
