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:

1. Read and fully understand all referenced documents provided by the user (design specs, architecture docs, implementation plans)
2. 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]

Workflow

flowchart TD
    A[Read Referenced Documents] --> B{Fully Understood?}
    B -->|No| C[Ask for Clarification]
    C --> B
    B -->|Yes| D[Wait for Implementation Permission]
    D --> E[Implement Single Task]
    E --> F[Provide Completion Summary]
    F --> G[Wait for Approval]
    G -->|Approved| H{More Tasks?}
    H -->|Yes| E
    H -->|No| I[Implementation Complete]

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
