Tools for your own build

Open utilities for AI coding agents.

Free, public listings for people who build with Cursor, Claude, Codex, and similar agents. This is not a client-services catalog. Live tools work without an account. Limits stay labeled honestly.

Live · MIT

Auto Model Router

Suggest the lightest sufficient model tier, then wait for you to confirm. The tool page has a playable motion replay of the real suggest → wait → confirm pass (Codex-style chat UI) and a separate illustrative CSS flow — not a billing claim. Install the skill or leave optional feedback. Email is never required.

GitHub install works today. cursor.directory is a community listing, not Cursor's official Marketplace. Official Cursor Marketplace and Claude community catalog: submitted, pending review.

Live · CLI

1stStep OS Audit

Free offline project audit. Evidence over docs, not README theater. Zero metered API cost path. Clone the CLI and run --help. Scores can be draft. It does not rewrite your repo.

Public GitHub today. Local Node CLI. Companion to the 1stStep OS free core. OS Cycle 1 is a local ZIP demo, not a hosted product.

Live · local Cycle 1

1stStep OS

Public free core for AI engineering. Cycle 1: idea → profile → Project OS markdown ZIP on your machine. Clone GitHub, run locally, open http://localhost:3000/os. Not a hosted product, full agent OS, or control plane.

Clone, then npm install && npm test && npm run build && npm start. No hosted ZIP generator on this site. Concept diagrams on /os stay illustrative.

More coming

Next tools stay unlisted until they exist.

Possible later directions include context-lean companions and other agent-usage helpers. Nothing else is named or linked here until it is public and usable, or honestly labeled as in development.

Need a custom dashboard or workflow for your business? That is a client service, not this tools shelf. Auto Model Router feedback and related-tool emails are opt-in only.
