Add to SourceWeft

You will be asked to sign in first, then taken straight to this skill.

Paste this prompt into Claude Code, Codex, Cursor or another agent that can run commands — or into SourceWeft chat. The agent reads this skill's install guide, shows you its source, license and scripts, and installs it with the SourceWeft CLI once you agree.

Read https://sourceweft.com/skills/gh-davila7-claude-code-templates-agent-tool-builder/install.md and install the skill it describes. Before installing, show me its source, license and whether it ships scripts, and wait for my OK. Ask me before changing anything else on my machine.

Read the install guide the agent follows

Install it yourself from a terminal

For Claude Code, Codex, Cursor and other local agents. The SourceWeft CLI fetches the skill from its source repository at the commit scanned here, and verifies every file against the hashes recorded when the skill was scanned. If anything differs, nothing is written.

npx @sourceweft/cli skills install @davila7/agent-tool-builder

Add --agent claude-code, codex, cursor or universal to choose which agent gets it (Claude Code by default).

Upstream installer — not verified by SourceWeft

The open-source skills installer fetches the same pinned commit, but does not check the files against the hashes SourceWeft recorded.
