How real projects brief Claude Code: the commands, conventions and warnings they put in CLAUDE.md.
Files you open will collect here, so you can find them again.

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…

A collection of Jupyter notebooks and Python examples for building with the Claude API. Or directly with uv: Notebooks have relaxed rules for mid-file imports (E402), redefinitions (F811), and variable naming (N803, N806). Branch naming: <username>/<feature-description> Commit format (conventional commits): These commands are available in Claude Code and CI:

AnthropicCLAUDE.mdanthropics/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…

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…

A Next.js chat app. assistant-ui renders everything; one Managed Agents session per conversation runs the analyst, and lib/managed-agents/reducer.ts folds each session's event log into the messages assistant-ui renders. The sidebar is the session list. There is no database. Needs Node 22+, @anthropic-ai/sdk 1.0 or later, and @assistant-ui/react 0.14.27 or later (the defineToolkit/Tools API and approvals on useExternalStoreRuntime).

AnthropicReads credentialsCLAUDE.mdanthropics/claude-quickstarts/managed-agents/daily-brief/CLAUDE.md
A scheduled deployment, not an app: there is no long-running process in this quickstart. agents/daily-brief/ holds six resource files that ant apply reconciles (agent, environment, two memory stores, vault, deployment). ant apply manages the vault container but never its contents, so agents/setup.sh adds the two credentials with ant beta:vaults:credentials create and writes the vault's ID into deployment.md's vault_ids (a deployment takes vault IDs, not a file reference). Each scheduled run is a fresh session: it reads /mnt/memory/preferences/preferences.md (read-only store), reads…

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…

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.
At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.
Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.
Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
