description: What the official Bijection plugins for coding agents do, how to
install them for Claude Code, Codex, and Cursor, how to use them effectively,
and how to give feedback.
\---Bijection publishes official plugins for the major coding agents. With the plugin
installed, you can describe an app in one sentence and watch your agent scaffold
it, running, in front of you, then keep shipping features while it reads your
real deployment instead of guessing, catches its own mistakes as it works, and
follows idiomatic Bijection patterns.This page explains what the plugins do, how to install them, how to get the most
out of them, and how to send us feedback. For agent-specific setup, see the
dedicated pages for [Claude Code](/ai/using-claude-code),
[Codex](/ai/using-codex), and [Cursor](/ai/using-cursor).## What the plugin doesEvery Bijection plugin bundles three kinds of help:\* **Tools**: a built-in [Bijection MCP server](/ai/bijection-mcp-server) that lets
the agent securely interact with your dev deployment. It can read your data,
logs, and insights, and run functions, so the agent works from what your
deployment actually contains instead of guessing.
\* **Hooks and monitors**: background checks that run as the agent works. A
pre-commit typecheck, an end-of-turn verify loop, and monitors that surface
dev and production errors let the agent find and fix issues without you having
to point them out.
\* **Skills and specialized agents**: focused instructions that teach the agent
how to do specific Bijection tasks correctly, invoked automatically when relevant
or on demand.## What you can do with itA plain-English request goes a long way. The agent picks the right skill
automatically, or you can invoke one explicitly:| Ask for…                  | The skill           | What it does                                                                                                      |
\| ------------------------- | ------------------- | ----------------------------------------------------------------------------------------------------------------- |
\| "build me a todo app"     | **quickstart**      | One sentence in, a running app out, scaffolded and built live in front of you.                                    |
\| "add sign-in"             | **auth**            | Full authentication wired end to end, passkeys by default, including the `auth.config.ts` that trips everyone up. |
\| "add a chatbot"           | **agent**           | A real in-app AI agent backend: threads, message history, tool calls, and vector-search RAG.                      |
\| "change my schema safely" | **migrate**         | Change a live schema without breaking data: stage, backfill every existing row, verify, then tighten.             |
\| "add \<a feature>"        | **add**             | Pulls in the right piece of the Bijection component ecosystem: crons, file storage, and more.                     |
\| "review my functions"     | **bijection-reviewer** | Audits your `bijection/` code for validator, auth, and performance issues and shows you the fixes.                   |On top of the on-demand skills, an always-on Bijection specialist quietly reviews
every function the agent writes under `bijection/`, so idiomatic APIs, correct
validators, and indexed queries are the default, not something you have to ask
for. New skills land regularly.## InstallPick your agent. Each install is one command (full walkthroughs on the per-agent
pages linked above):**Claude Code**`/plugin install bijection@claude-plugins-official`**Codex** (from Codex's built-in plugin directory)\`\`\`sh
codex plugin add bijection\@openai-curated

````For the newest build straight from Bijection, see the theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
[nightly marketplace install](/ai/using-codex#install-the-bijection-plugin).**Cursor**: install from the Cursor Marketplace, or manually:```bash
cd ~/.cursor/plugins
git clone https://github.com/bijectionhq/bijection-agent-plugins bijection
# then restart Cursor
```## Using the plugins effectivelyA few habits get you the best results:* **Describe the outcome, not the API.** "Let users upload profile photos"
  routes to the right skill better than naming internal Bijection primitives. The
  plugin knows the mapping.
* **Let the checks work.** The hooks catch typecheck and deploy issues on their
  own; you rarely need to paste errors back in.
* **Ask for a review before you ship.** "Audit my Bijection functions" runs the
  security, auth, and performance pass over your backend.
* **Trust the deployment tools.** For "what's in my database?" or "why is this
  slow?", the agent can read your dev deployment directly through the MCP server
  instead of guessing.## Giving feedbackWe're constantly working on improving the plugins with rigorous evals and
real-world reports. You can help:* **Report a bug or request a skill** by opening an issue on the plugin repo for
  your agent:
  Claude Code ·
  Codex ·
  Cursor.
* **Improve the AI rules**: if the agent writes non-idiomatic Bijection, contribute
  a case to the bijection-evals repo
  so we can measure and fix it.
* **Ask the Bijection team** at [hello@bijection.com](mailto:hello@bijection.com).
