You must get explicit approval before implementing.**\n\nWhen the user presents a topic, idea, or asks you to look at something, they want analysis and options — not code changes. Jumping to implementation without approval is the most common workflow violation.\n\n## When to Ask\n\nBefore you:\n- Edit any project file (code, config, data)\n- Create a new file\n- Run mutating terminal commands (install, deploy, restart services)\n- Make any irreversible change\n\n**STOP and ask**: \"Here's what I'd propose doing. Shall I go ahead?\"\n\n## Approval Signals\n\nOnly these count as approval to proceed:\n- \"Yes\" / \"Go ahead\" / \"Implement it\" / \"Do it\"\n- \"Let's do it\" / \"Proceed\" / \"Start\"\n- Clear directive like \"Change X to Y\"\n\n## NOT Approval Signals\n\nThese do NOT mean \"implement now\":\n- \"Let's move to point 4\" — discussing next topic, not authorizing changes\n- The user explaining what they want — they're still shaping the requirement\n- Silence after your analysis — they haven't said yes\n- Your own enthusiasm about a solution — excitement ≠ permission\n\n## What to Do Instead\n\n1. **Analyze** — read code, understand the problem, investigate\n2. **Present options** — lay out the approach with trade-offs\n3. **Wait for yes** — the user decides when to execute\n4. **Then implement** — once you have clear approval\n\n## Why This Matters\n\n- Premature implementation wastes time when the user is still deciding\n- Changes may conflict with the user's mental model if they haven't approved the approach\n- Reverting code changes is expensive (especially without git)\n- Discussion reveals requirements and edge cases before code is written\n\n## Example Violations\n\n❌ User: \"let's move to point 4\" → Agent immediately starts coding T4.1\n✅ User: \"let's move to point 4\" → Agent analyzes T4, presents plan, asks \"Want me to start on this?\"\n\n❌ User: \"tell me about pain point 4\" → Agent reads all files and patches 3 bots\n✅ User: \"tell me about pain point 4\" → Agent explains the situation and asks how to proceed\n\n## Exceptions\n\nThe only time to implement without explicit approval:\n- The user gave approval earlier in the session for the same task\n- Trivial, non-destructive read-only operations (listing files, readin ...
