compete

You orchestrate a competition between 3 independent implementation attempts. Each uses a different strategy. A neutral judge picks the winner. The loser branches are deleted.

Read the spec or feature description from: $ARGUMENTS

Phase 1: Setup

1. Read and understand the spec / acceptance criteria.
2. Identify the current branch. Store it as BASE_BRANCH.
3. Create 3 competition branches from BASE_BRANCH:
   • compete/minimal — Strategy A
   • compete/thorough — Strategy B
   • compete/creative — Strategy C

Phase 2: Implement (3 rounds)

For EACH strategy below, checkout the corresponding branch and use the implementer agent to execute. Pass the strategy directive along with the original spec.

Strategy A: Minimal (compete/minimal)

Implement the spec with the fewest lines of code possible. Prefer reusing existing utilities, composing existing functions, and leveraging framework conventions. No new abstractions. No new files if avoidable. The best code is code you didn't write.

Strategy B: Thorough (compete/thorough)

Implement the spec with comprehensive edge case handling from the start. Validate all inputs. Handle every error path. Add more tests than the spec requires — boundary values, empty inputs, malformed data, concurrent access if applicable. Prefer robustness over brevity.

Strategy C: Creative (compete/creative)

Implement the spec using an unconventional approach. Look for a different data structure, a different algorithm, a different decomposition than the obvious one. Challenge assumptions in the spec if they constrain a better solution. The goal is a fresh perspective — not cleverness for its own sake.

After each implementation, return to BASE_BRANCH before starting the next.

Phase 3: Judge

1. Return to BASE_BRANCH.
2. Use the judge agent to evaluate all 3 branches.
3. The judge runs {{verify_command}} on each, eliminates failures, and scores the survivors.

Phase 4: Merge the Winner

1. Merge the winning branch into BASE_BRANCH: git merge {winning-branch}
2. Delete all 3 competition branches:

   git branch -D compete/minimal
   git branch -D compete/thorough
   git branch -D compete/creative
   

3. Run {{verify_command}} one final time on the merged result.

Phase 5: Report

Print a summary:

## Competition Complete

Winner: [strategy name] (compete/[branch])
Score: [X/25]

### Why it won
[Judge's reasoning]

### Cherry-picked from runners-up
- [Any improvements merged from other branches, or "None"]

### Final verification
[pass/fail]

Rules

• Each strategy gets one shot. No retries, no "let me try a different approach."
• Strategies must be independent. Do not let one implementation influence another.
• The judge's verdict is final. Do not override it.
• If all 3 fail verification, STOP and report. Do not attempt a 4th strategy.
• Clean up ALL competition branches when done, regardless of outcome.
