/spec:challenge#

Runs the Contrarian agent to systematically challenge all decisions in the Seed spec.

Usage#

/spec:challenge                      # Target the latest Seed spec
/spec:challenge --file {path}        # Target a specific file
/spec:challenge --focus {section}    # Focus on a specific section

Parameters#

Execution Flow#

1. Load Seed Spec#

• Read target file
• Parse each section

2. Generate Challenges#

Generate challenges using 4 techniques:

Assumption Attack

• For each immutable constraint (S2): "What if this disappeared?"
• For each exposed assumption (S5): "What if the opposite were true?"

Scale Challenge

• "Users 10x", "Data 100x", "Concurrent requests 1000x"

Removal Test

• For each domain entity (S3): "Can this be solved without it?"
• For each Must item (S4): "Does the core value hold without this?"

Historical Challenge

• Present common failure causes from similar projects

3. Severity Classification#

• Critical: Could invalidate the project
• Major: Would impact key features
• Minor: Partial impact

4. Collect User Responses#

• Collect user answers/responses for each challenge
• Classify as resolved / unresolved / accepted based on responses

5. Generate Report#

• Save Contrarian review report

Output#

Report content printed to console; key challenges/responses recorded in the Seed spec's decision log.
