+# Agent Policy
+
+This document defines execution rules for automation agents contributing to this repository.
+Wording is intentional and consistent with [CONTRIBUTING.md](../CONTRIBUTING.md) and existing CI guidance.
+
+## Rust Post-Change Commands
+
+After any Rust source change, run exactly the following two commands before opening or updating a pull request:
+
+```bash
+cargo fmt
+cargo clippy --all-targets --no-deps --features telemetry-otel -- -W clippy::pedantic
+```
+
+No additional Rust commands are required in this iteration.
+
+## Commit Message Requirement
+
+For every completed task with repo changes, include a Conventional Commit message draft with a scope (`type(scope): summary`). This includes interactive sessions and autonomous agents that are allowed to create commits directly.
+
+## Docs Sync Requirements
+
+When a change affects observable behavior, CLI usage, or workflow, update the following in the same pull request:
+
+1. `README.md` — keep usage examples and command reference current.
+2. `docs/` — update any affected content pages (getting-started, configuration, etc.).
+3. `templates/skills/99problems/SKILL.md` — update when skill usage or workflow steps change.
+
+If a docs page does not exist yet for new behavior, create it under `docs/` and register it in `mkdocs.yml`.
+
+## Scope Boundaries
+
+- This policy covers only agent-driven contributions; human contributors follow [CONTRIBUTING.md](../CONTRIBUTING.md).
+- No runtime code changes may be introduced solely by this policy file.
+- No new CI jobs or workflow changes are implied by this document.
+- Do not expand the mandatory Rust command list without a separate policy revision.
