spec-kit / integrations

github/spec-kit/docs/integrations/claude.md

Install Claude Code before setup. The integration key is claude. This integration is declared multi-install safe. See the shared multi-install rules. For an existing Spec Kit project, use specify integration install claude. See integration management for activation, upgrades, and removal. Skills are installed as .claude/skills/speckit-<command>/SKILL.md. Invoke them in Claude's chat, for example /speckit-specify or /speckit-bug-assess for the installed bug extension. By default every Spec Kit skill installed for Claude Code is model-invocable, so its description is always in Claude's context…

financial-services

anthropics/financial-services/CLAUDE.md

Cowork plugins and Claude Managed Agent templates for financial services. Each named agent ships two ways from one source. Run python3 scripts/check.py before committing — it lints every manifest, verifies all system.file / skills.path / callable_agents.manifest references resolve, fails if any agent-plugins/<slug>/skills/ copy has drifted from its vertical-plugins/ source, and rejects non-ASCII bytes in a .ps1 without a UTF-8 BOM. Keep .ps1 files pure ASCII. Windows PowerShell 5.1 — still the default shell on managed Windows — decodes a BOM-less…

playwright-mcp

microsoft/playwright-mcp/CLAUDE.md

The MCP server source lives in microsoft/playwright, in packages/playwright-core/src/tools/. This repo ships @playwright/mcp: cli.js and index.js run the server from the playwright-core alpha that package.json pins. config.d.ts is a copy of the upstream file, and npm run lint generates the tool list in README.md. There is no build step. Tests are in tests/*.spec.ts, with test and expect from ./fixtures. The client fixture is an MCP client that runs cli.js over stdio, startClient() starts one with args or a config, and…

claude-quickstarts / chat-sdk

anthropics/claude-quickstarts/managed-agents/chat-sdk/CLAUDE.md

Long-running Node server (Hono): browser chat with a sessions sidebar (useChat → /api/chat) → Chat SDK web adapter onDirectMessage → one Managed Agents session per conversation, where the conversation ID is the session ID (no mapping, no database; the sidebar is sessions.list, transcript replay is sessions.events.list) → a held session event stream (opened with event_deltas token previews, always on) feeds each fragment back onto the same HTTP response while /api/activity streams the tool calls and thinking the page shows as…

claude-quickstarts / knowledge-wiki

anthropics/claude-quickstarts/managed-agents/knowledge-wiki/CLAUDE.md

This directory is a Managed Agents quickstart: it builds a real M&A data room into a knowledge wiki (a versioned memory store) with one dynamic workflow run, and queries it. The runnable artifact is distill_documents_into_knowledge_wiki.ipynb; prompts/ holds the consolidation agents' prompts, the lead agent's prompt and the baseline analyst's prompt, utilities.py the notebook's functions; everything else exists to set that notebook up. When a user asks you to walk them through setting this quickstart up, read skill.md in this directory…

claude-quickstarts / mcp-server-typescript

anthropics/claude-quickstarts/managed-agents/mcp-server-typescript/CLAUDE.md

MCP server that exposes Managed Agents session primitives as tools. Two entrypoints sharing one tool set: src/server.ts (stdio → Claude Desktop and Claude Code) and src/server-http.ts (Streamable HTTP → claude.ai custom connector). This quickstart creates no agents, so there is no agents/ directory. It needs one environment, created once from environment.yaml (the command is in that file and in README.md). Commands: bun run stdio (Desktop, Code), bun run http (claude.ai), bun run typecheck.

claude-quickstarts / roadtrip-planner

anthropics/claude-quickstarts/managed-agents/roadtrip-planner/CLAUDE.md

A Next.js chat built directly on a Managed Agent session: no chat framework, the event log is the app state. Teaches session event streaming (event_deltas), vault credential injection_location, per-session agent_with_overrides, and multiagent coordinator rosters. The planner calls the National Park Service and Windy APIs with keys it never holds, then hands its draft to a second agent for a quick critique. That second agent is an Opus reviewer running as a session thread. 1. Invoke /claude-api first. It loads the…

playwright-cli

microsoft/playwright-cli/CLAUDE.md

The CLI source lives in microsoft/playwright, in packages/playwright-core/src/tools/. This repo ships @playwright/cli: playwright-cli.js runs the CLI of the playwright-core alpha that package.json pins, and adds the update check, with skillCheck.js. skills/playwright-cli/ is a copy of the skill that playwright-cli install --skills writes, and node scripts/update.js refreshes it. There is no build step and no lint. Tests are in tests/integration.spec.ts. They run playwright-cli.js with runCli() in the output directory of the test, and the npmRegistry fixture serves a fake registry for…
