synapse-a2a

Design, review, and improve Claude/Codex skills based on Anthropic's "The Complete Guide to Building Skills for Claude". Use when creating a new skill, rewriting SKILL.md frontmatter and workflows, fixing under-triggering or over-triggering, designing scripts/references/assets, building test cases, or preparing a skill for upload/distribution.

Guide API design for REST, GraphQL, gRPC, and CLI interfaces. Use this skill when designing new APIs, reviewing existing API contracts, or establishing API conventions for a project. Produces consistent, well-documented API specifications.

Perform structured code reviews focusing on correctness, readability, security, and maintainability. Use this skill when reviewing pull requests, evaluating code changes, or establishing review standards for a team.

Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Focuses on recently modified code unless instructed otherwise. This skill should be used when code-quality checks pass but the code would benefit from structural cleanup — deduplication, branching simplification, naming improvements, or dead-code removal. Invoked as a subagent from /code-quality or directly via the Task tool.

Audit, restructure, and consolidate project documentation for clarity and maintainability. Use this skill when docs have grown organically and need reorganization, when duplicate content exists across files, or when documentation structure needs standardization.

Guide for creating distinctive, production-grade frontend interfaces. Covers visual design systems, typography, color, motion, spatial composition, and web interface standards. Use when designing UI, establishing design systems, or reviewing visual quality of frontend code.

Runs synapse-docs, /simplify, sync-plugin-skills, and github-pages-sync in parallel for synapse-a2a development workflows. Use when you need doc updates, code simplification, plugin skill sync, and site-docs sync at the same time.

Continuously monitor a GitHub PR for merge conflicts, CI failures, and CodeRabbit review comments, then automatically fix any issues found. Polls every 5 minutes and loops until every check is green. Use this skill whenever a PR has just been created or code has been pushed to a PR branch — it should be the default follow-up action after any PR creation or push. Also trigger on: "watch this PR", "guard this PR", "monitor CI", "keep fixing until green", "PRを監視して", "CIが通るまで 直して", /pr-guardian. When a PostToolUse hook reports that a push or PR creation just happened, proactively invoke this skill to start monitoring without waiting for the user to ask.

Guide for creating and maintaining project documentation (README, guides, API specs). Emphasizes doc/code synchronization, consistency checks, and use of the docs-excellence-architect subagent.

React component composition patterns for building flexible, maintainable UIs. Covers compound components, context-based state, explicit variants, and React 19 APIs. Use when designing component APIs, refactoring prop-heavy components, or building reusable component libraries.

Best practices for React Native and Expo applications. Covers list performance, animations with Reanimated, navigation, UI patterns, and monorepo configuration. Use when building, reviewing, or optimizing React Native / Expo apps.

Comprehensive React and Next.js performance optimization guide. Covers waterfall elimination, bundle size reduction, server-side optimization, re-render prevention, and rendering performance. Use when building, reviewing, or optimizing React/Next.js applications for speed.

Guide for safe and effective code refactoring. Focuses on improving code structure without changing external behavior. Covers patterns like extraction, inlining, and naming improvements.

Update version in pyproject.toml, plugin.json, and add changelog entry. This skill should be used when the user wants to bump the version number and update CHANGELOG.md. Triggered by /release or /version commands.

General-purpose security auditing guide. Covers OWASP Top 10, dependency vulnerabilities, authentication, authorization, input validation, and secret management. Use this when performing a security review or audit.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Synapse A2A agent communication -- sending messages, spawning agents, delegating tasks, sharing memory, managing the LLM wiki, and coordinating file edits. Use this skill when: running synapse send/reply/broadcast/interrupt, spawning agents with synapse spawn or synapse team start, sharing knowledge with synapse memory, managing wiki pages with synapse wiki, locking files with synapse file-safety, checking agent status with synapse list/status, or orchestrating any multi-agent workflow. For AI/programmatic use, prefer synapse list --json, synapse status <target> --json, or the MCP list_agents tool instead of interactive synapse list.

Multi-agent management workflow — task delegation, progress monitoring, quality verification with regression testing, feedback delivery, and cross-review orchestration. Use this skill when coordinating multiple agents on a shared task, monitoring delegated work, ensuring quality across agent outputs, or implementing a multi-phase plan (3+ phases or 10+ file changes).

Re-inject Synapse A2A initial instructions after context has been cleared. Use this skill when the agent has lost its identity, A2A communication protocol, or configuration after /clear or context reset, when synapse send/reply commands stop working, or when the agent no longer recognizes its SYNAPSE_AGENT_ID. Triggered by /synapse-reinst command.

Guide architectural design decisions for software systems. Use this skill when designing new systems, evaluating architecture trade-offs, or creating technical design documents. Helps produce clear, well-structured design artifacts including component diagrams, data flow, and decision records.

Guide for decomposing large tasks into a structured plan with dependency chains, managing priorities, and distributing work across agents. Outputs plan cards or delegation messages as the team contract; TodoList for personal micro-steps.

Guide for Test-First (Test-Driven) Development. Focuses on writing tests before implementation, ensuring comprehensive coverage and clear requirements. Covers test design, edge cases, and the Arrange-Act-Assert structure.

Web accessibility and interface standards guide. Covers WCAG compliance, semantic HTML, keyboard navigation, screen readers, forms, touch targets, and internationalization. Use when building, reviewing, or auditing web interfaces for accessibility and UX quality.
