Overview

Prompter is a CLI that connects your project to Anvil's skill catalog. Skills are not bundled inside the npm package — they are fetched from Anvil's registry when you run `prompter init`, according to the plan you own.

Each skill is an instruction package your AI coding agent reads (Claude Code, Codex, Copilot, OpenCode, and others). Instead of rewriting long prompts in every project, you install a skill once and invoke it by name.

Beyond skills, Prompter also brings a spec-driven workflow: every significant change starts from a validated proposal, not straight from code.

Install the CLI first, then follow the quickstart to take a single change from proposal all the way to archived.
