+- No LLM Judge.
+- Subagents are advisory only (no PASS/FAIL authority).
+- MCP output is treated as untrusted input.
+- Hooks policy/audit templates only (no live execution).
+- All paths must be repo-relative.
+
+## Allowed
+- Modifying `src/cli.rs` and `tests/cli_smoke.rs` to implement the `antigravity` command and its tests.
+- Creating the `templates/antigravity` directory and template files.
+
+## Forbidden
+- Performing live network calls or using cloud APIs.
+- Global installation steps.
+- Creating files outside the workspace root.

+# Antigravity Plugin Bundle Specification
+
+This document specifies the architecture, boundaries, and components of the Antigravity Plugin Bundle system in the CompText CLI ecosystem.
+
+## Architectural Principles
+
+1. **Deterministic Control**:
+   CompText serves as the deterministic Evidence-Control-Plane. Every context pack, state report, and proposal is strictly structured, schema-checked, and local.
+   
+2. **Execution Surface**:
+   Antigravity acts as the Agent Execution Surface. It processes agent commands, imports/exports configurations, and manages local tools/skills.
+   
+3. **No LLM Judge**:
+   There is no LLM-based verification authority. Autonomy and state transition checks must rely purely on deterministic local validations (e.g. check-sum, compilation, pattern matching).
+
+4. **Advisory Subagents**:
+   Subagents (e.g., in `.agents/`) are advisory-only. They lack the authority to issue PASS/FAIL verdicts. Only local CLI tools verify execution states.
+
+5. **Untrusted Protocol Boundaries**:
+   MCP outputs, external APIs, and model-provided patches are treated as untrusted input. They must pass validation and audit gates before application.
+
+6. **Hooks Policy Audits**:
+   Hooks configured in the bundle (e.g. `hooks.json`) are templates used for linting and safety checks. They are not executed live in the CLI engine at runtime.
+
+7. **Repo-Relative and Sandboxed Paths**:
+   All paths configured or accessed by plugin bundles must be repo-relative. Absolute paths are strictly forbidden to ensure isolation.
+
+## Component Structure
+
+A standard Antigravity Plugin Bundle consists of the following components:
+- `plugin_manifest.json`: Root metadata containing dependencies, permissions, and paths.
+- `skills/`: Local skill folders with detailed instructions and boundaries (`SKILL.md`).
+- `rules/comptext-rules.md`: Bounded execution markdown checklists.
+- `hooks/hooks.json`: Interception rules and policy templates.
+- `mcp/mcp_config.json`: Configuration for local Model Context Protocol servers.
+- `permissions/permissions.template.json`: Declared permissions for actions (e.g. `command`, `write_file`, `read_url`, `mcp`).
+- `agents/`: Specifications for advisory subagents.

+- **NETWORK**: offline-only
+- **SECRETS**: No credentials accessed or exposed.
+- **POLICY_DECISIONS**: All design boundaries respected (no live runtime hooks, advisory-only subagents, MCP treated as untrusted, no LLM judge).
+- **RISKS**: None. Skeleton command layer validated via integration tests.
+- **NEXT**: Await Review-Gate approval.
