tool-selection
CLI-first tool selection policy for Claude Code. Use when choosing between CLI tools and MCP servers, designing new agents, or reviewing agent tool configurations. Do NOT use for executing commands or running tools -- this is for tool selection decisions during agent/config design only.
npx skills add majiayu000/claude-skill-registry --skill tool-selection-cooldaemon-dotfiles --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Tool Selection Policy ## CLI-First Principle Prefer CLI tools over MCP servers when a CLI equivalent exists. CLI tools are more token-efficient and avoid MCP server startup overhead. | Tool Need | CLI (Preferred) | MCP (When CLI Insufficient) | |-----------|----------------|----------------------------| | Screenshots & screen analysis | `peekaboo` CLI via Bash | N/A (removed) | | Web research | WebSearch, WebFetch (built-in) | N/A | | Library API docs | See web-research skill | context7 MCP (see web-research skill) | | Interactive browser control | N/A | Playwright MCP | | E2E testing | Playwright CLI (`npx playwright test`) | N/A | | Slack communication | N/A | Slack MCP (no CLI substitute) | | Confluence wiki | N/A | Confluence MCP (no CLI substitute) | ## Playwright MCP vs CLI **Use Playwright MCP** (`mcp__playwright__*`) ONLY for: - Interactive browser inspection (snapshots, clicking, form filling) - Live debugging of web pages - Visual verification requiring human-in-the-loop **Use Playwright CLI** for: - E2E test execution (`npx playwright test`) - Test report generation - CI/CD pipeline testing ## Playwright MCP Output Management The `.playwright-mcp/` directory in the pro

What does the tool-selection skill do?
CLI-first tool selection policy for Claude Code. Use when choosing between CLI tools and MCP servers, designing new agents, or reviewing agent tool configurations. Do NOT use for executing commands or running tools -- this is for tool selection decisions during agent/config design only.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill tool-selection-cooldaemon-dotfiles --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
