agent-policy

Schema-first generator for coding-agent repo policies and compatibility files.

Generates AGENTS.md, CLAUDE.md, and .cursor/rules/ from a single agent-policy.yaml.

What it does

Maintaining AGENTS.md, CLAUDE.md, and Cursor rules separately means the same policy information gets duplicated across files that diverge over time. agent-policy solves this by letting you define your repo's coding-agent policy once in a canonical agent-policy.yaml, then generating all the tool-specific compatibility files from that single source of truth.

Keep one policy file. Generate all agent instruction files from it. Detect drift in CI.

Install

From crates.io

cargo install agent-policy

Binary releases

Download pre-built binaries from GitHub Releases.

Quick start

# Create a starter policy
agent-policy init

# Edit agent-policy.yaml, then generate
agent-policy generate

# Add to CI to prevent drift
agent-policy check

Commands

Command	Description
`agent-policy init`	Write a starter `agent-policy.yaml` in the current directory
`agent-policy generate`	Generate all enabled output files from `agent-policy.yaml`
`agent-policy check`	Verify committed files match the current policy (CI use)

Both generate and check accept --config / -c to specify a non-default config path:

agent-policy generate --config infra/agent-policy.yaml
agent-policy check -c path/to/agent-policy.yaml

agent-policy.yaml

Minimal example:

project:
  name: my-project
  summary: A short description.
outputs:
  - agents-md

Full example — see examples/website/agent-policy.yaml.

The file is validated against agent-policy.schema.json (JSON Schema Draft 2020-12). The schema is bundled with the binary and is versioned alongside it. It is considered unstable until v1.0.0.

Generated outputs

Target ID	File	Enabled by default
`agents-md`	`AGENTS.md`	Yes
`claude-md`	`CLAUDE.md`	No
`cursor-rules`	`.cursor/rules/default.mdc` + one per role	No

When cursor-rules is enabled and roles are defined, agent-policy generates one .mdc file per role with globs set to the role's editable paths, so Cursor activates the rule automatically based on which file is open.

CI integration

Add to your CI workflow to enforce that generated files are never edited by hand:

- name: Check agent policy
  run: agent-policy check

This step exits non-zero if any generated file is stale or missing, and prints a unified diff to stderr.

Non-goals

Not a replacement for AGENTS.md — it generates AGENTS.md
Not a full enforcement engine or policy-as-code runtime
Not a SaaS platform or hosted service
Not a daemon or background process
