+# AGENTS - Plugin Module
+
+## Working Directory
+- `src/Plugin/**` (plugin registry, host, sandbox, SDK, tests).
+
+## Required Reading
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/modules/release-orchestrator/README.md`
+- `docs/modules/release-orchestrator/modules/plugin-system.md`
+- `docs/modules/sdk/README.md`
+
+## Engineering Rules
+- Deterministic plugin discovery and manifest processing.
+- Sandbox and capability checks must fail closed.
+- No network access during tests; use local fixtures.
+
+## Testing & Verification
+- Tests live in `src/Plugin/__Tests/**`.
+- Cover registry, sandbox, and SDK compatibility scenarios.
+
+## Sprint Discipline
+- Record plugin contract changes in sprint Decisions & Risks and docs.
