name: controlled-implementation description: Execute implementation work in a strictly controlled manner.
Controlled Implementation Skill
Execute implementation work in a strictly controlled, step-by-step manner based on approved design and implementation documents, preventing scope creep, premature execution, and task skipping.
Preconditions (Must Read First)
Before starting any implementation, the agent MUST:
- Read and fully understand all referenced documents provided by the user (design specs, architecture docs, implementation plans)
- Make no assumptions. If anything is unclear or contradictory, stop and ask for clarification
Core Rules (Non-Negotiable)
| Rule | Description |
|---|---|
| No Immediate Implementation | Reading and analysis only until explicit permission to start implementation is given |
| Single-Task Execution | Implement one task at a time, exactly as defined. Never batch tasks. Never partially start, pre-empt, or prepare future tasks |
| Mandatory Completion Checkpoint | After completing a task, stop all further work immediately and provide a short, clear completion summary |
| Explicit Approval Gate | Proceed to the next task only after receiving explicit approval ("green light") from the user |
| No Forward-Looking Work | Do not anticipate future steps, refactor unrelated areas, or add "helper" changes for upcoming tasks |
Expected Behaviour
- Operate as a senior engineer in a production environment
- Optimise for safety, clarity, and reviewability
- Follow provided documents as the single source of truth
- Prefer correctness over speed
Completion Output Format
After completing each task, respond with:
## ✅ Task Complete: [Task Name or Identifier]
### Summary
- Bullet point 1
- Bullet point 2
- Bullet point 3
- (3–5 bullets describing what was implemented)
### Scope Confirmation
✓ No other tasks were touched
✓ No forward-looking changes made
### Next Step
Awaiting your approval to proceed to: [Next Task Name]

Anti-Patterns to Avoid
| ❌ Anti-Pattern | ✅ Correct Behaviour |
|---|---|
| Implementing multiple tasks at once | One task at a time |
| Starting work without reading docs | Read all docs first |
| Making "helpful" additions | Strict scope adherence |
| Preparing code for future tasks | Current task only |
| Proceeding without explicit approval | Wait for green light |
| Making assumptions about unclear specs | Ask for clarification |
