This skill audits and updates repository `CLAUDE.md` files. It runs shell commands such as `find . -name "CLAUDE.md" -o -name ".claude.local.md"` and can write/update `CLAUDE.md` and `./.claude.local.md`.

This skill builds single-file HTML playgrounds from templates in `templates/` for visual exploration and prompt generation. It includes explicit shell instructions such as `open <filename>.html` and `git show <commit> --format="%H%n%s%n%an%n%ad" -p`, which are low-risk static shell executions.

This skill provides best-practice guidance for building Stripe integrations (e.g., `CheckoutSessions`, `PaymentIntents`, Billing, Connect) and references `docs.stripe.com` for details. No security-relevant behaviors detected.

This skill analyzes a codebase and recommends Claude Code automations (MCP servers, hooks, skills, subagents, plugins). It explicitly instructs running shell commands like `ls -la` and `cat package.json` and using `!`command`` injection, recommends checking `.mcp.json` into git, and directs `web search`/MCP integrations such as `context7`.

This skill documents how to create Claude Code plugin skills, including structure, resources, and best practices. It contains explicit instructions to run CLI scripts such as `scripts/init_skill.py`, `scripts/package_skill.py`, and `cc --plugin-dir /path/to/plugin`, which directs shell command execution.

This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.

This skill provides guidance, examples, and scripts for implementing Claude Code plugin hooks (prompt and command hooks, configuration, and testing). It enables executing shell commands (e.g., `"command": "bash ${CLAUDE_PLUGIN_ROOT}/scripts/validate.sh"`), persisting env vars to `"$CLAUDE_ENV_FILE"`, and external calls using `"$SLACK_WEBHOOK"`/`"$DATABASE_URL"`.

This skill documents how to author Claude Code slash commands, covering frontmatter, `@` file references, argument substitution, and bash/script integration. It instructs executing shell commands (e.g., `!`bash ${CLAUDE_PLUGIN_ROOT}/scripts/build.sh`), accessing plugin files via `@${CLAUDE_PLUGIN_ROOT}`, requesting broad `allowed-tools` (`allowed-tools: "*"`, `Bash(*)`), and calling CLI APIs like `gh api /deployments/$1`.

This skill documents how to integrate MCP servers into Claude Code plugins, including `stdio`, `sse`, `http`, and `ws` configurations. It explicitly instructs spawning local processes via `command`/`args`, executing shell commands (`claude --debug`, `source .env`), using secret env vars like `${API_TOKEN}`, and contacting endpoints such as `https://api.example.com/mcp`.

This skill documents the `.claude/*.local.md` per-project settings pattern and includes templates and examples. It provides executable shell scripts and commands (e.g., `read-settings-hook.sh`, `parse-frontmatter.sh`, `tmux send-keys`, `cat > ... <<EOF`) that instruct running shell actions.

This skill documents Claude Code plugin structure, manifest fields, component locations, and best practices for scaffolding plugins. It includes executable hooks (e.g., `bash ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/security/scan-secrets.sh`, `hooks/scripts/validate-commit.sh`), MCP server env bindings like `GITHUB_TOKEN` and `API_KEY`, and examples calling external services (`tools.github_actions_trigger_workflow`, `SlackClient.notify`).

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
