Development Lifecycle Orchestration

Follow this rigorous loop for any non-trivial step.

Phase 1: Research & Discovery

Gather context before proposing changes.

• Map Dependencies: Use filesystem to find relevant files and imports.
• Trace Logic: Use grep to understand data flow and symbol usage.
• Reference Docs: Use context7 for external libraries.
• Check History: Use git to see how code evolved.

Phase 2: Strategy & Planning

Define the "What" and "How" before implementation.

• Identify every file to be modified.
• Outline the logic changes.
• Define Verification: Plan how success will be proven.

Phase 3: Implementation (The Edit Loop)

Execute minimal, verified changes.

• Use filesystem for surgical edits.
• Follow existing project patterns and style.
• Prefer composition and simplicity over abstractions.

Phase 4: Verification & Hardening

Apply the verification workflow.

• Repro First: Confirm the bug/absence of feature.
• Verify Fix: Prove the change works.
• Regression Test: Ensure no collateral damage.

Core Principles

1. Read before Write: Context is everything.
2. Surgical Precision: Minimal changes for maximum effect.
3. Evidence over Assertion: Prove it works with output.
4. Root Cause Fixes: Fix the source, not the symptom.
5. Simplify Continuously: Leave the codebase cleaner than you found it.
