plan: add commit approval system for AI agents

 ## 3. Implementation & Committing
 
 - **Small, Atomic Commits**: Changes should be broken down into small, logical commits.
-- **Pre-Commit Approval**: The agent MUST ask for user approval before every `git commit` operation, presenting the proposed commit message.
+
+### Commit Protection System
+
+**OpenCode automatically prevents unauthorized commits** via the permission system defined in `opencode.json`:
+- `"git commit *": "deny"` blocks all direct commit attempts by agents
+- Environment variables (`OPENCODE=1`, `OPENCODE_PROCESS_ROLE=worker`) identify agent context
+- This protection is automatic and cannot be bypassed by agents
+
+### Proper Commit Workflow for Agents
+
+1. **Request Approval**: Before committing, the agent MUST ask the user explicitly:
+   - Present the proposed commit message
+   - Show what changes will be included (`git status`, `git diff`)
+   - Wait for explicit user confirmation (e.g., "yes", "proceed", "commit")
+
+2. **User Executes Commit**: After approval, the **user** runs the commit command:
+   - User types: `git commit -m "the agreed message"`
+   - OR user can modify the message and commit manually
+
+3. **Agent Never Commits Directly**: Agents must never attempt `git commit` commands
+   - Such attempts will be blocked by OpenCode's permission system
+   - Instead, agents should guide users through the commit process
+
+### Troubleshooting Commit Issues
+
+- **"Permission denied" errors**: Normal behavior - agents cannot commit directly
+- **Agent claims to commit**: Bug in agent logic - agent should request approval instead
+- **Manual commits failing**: Check if you're in an agent session vs manual terminal
+
+### Example Proper Commit Request
+
+```
+I've completed the feature implementation. Here are the changes ready to commit:
+
+**Proposed commit message**: "Add dark mode toggle to settings page"
+
+**Files changed** (git status):
+- src/components/Settings.tsx (modified)
+- src/styles/themes.css (new file)
+
+**Summary of changes** (git diff --stat):
+- Added toggle component with state management
+- Implemented CSS variables for theme switching
+
+Please review and run: `git commit -m "Add dark mode toggle to settings page"`
+```

+# Plan: Commit Approval System for AI Agents
+
+- **Feature**: Implement a system to prevent AI agents from committing code without explicit user approval
+- **Branch**: `feature/commit-approval-system`
+- **Status**: `In Progress`
+- **Depends On**: None
+- **Summary**: Research and implement safeguards to ensure AI agents always ask for user permission before making git commits, addressing the issue of unauthorized commits despite instructions.
+
+---
+
+### Acceptance Criteria
+
+- Documentation clearly explains existing OpenCode commit protections
+- Workflow instructions are explicit about pre-commit approval requirements
+- Agents understand how to properly request commit approval
+- Manual human commits work without friction
+- Clear guidance on troubleshooting commit permission issues
+
+### Research Findings
+
+**OpenCode already prevents unauthorized commits via:**
+1. `opencode.json` permission system: `"git commit *": "deny"` for plan/general agents
+2. Environment variables: `OPENCODE=1`, `OPENCODE_RUN_ID`, `OPENCODE_PROCESS_ROLE=worker`
+3. Workflow requirement: `.opencode/docs/AGENT_WORKFLOW.md:34` mandates pre-commit approval
+
+**Root issue:** Agent compliance with existing instructions, not missing safeguards.
+
+### Checklist
+
+- [x] **(Mandatory)** Research OpenCode-specific integration points and commit mechanisms
+- [x] **(Decision)** Evaluate strategy: OpenCode's existing permission system is sufficient
+- [ ] **(Mandatory)** Update workflow documentation to clarify existing protections
+- [ ] **(Mandatory)** Add explicit guidance for agents on commit approval workflow
+- [ ] **(Mandatory)** Document troubleshooting steps for commit permission issues
+- [ ] **(Optional)** Add examples of proper commit request patterns
+- [ ] **(Mandatory)** Test documentation with current OpenCode setup
+- [ ] **(Mandatory)** Verify changes by running the type checker and unit tests
