Mission Planning

Step 1: Requirements

Ask: What to build? Tech stack? Boundaries? Testing strategy? Credentials?

Step 2: Investigate

Read: README, package.json, dir structure, test infra, DB schema, routes.

Step 3: Milestones

Define vertical slices. Foundational first. Get user agreement.

Step 4: Validation Contract (.mission/validation-contract.md)

For each feature area, write assertions:

• VAL-AREA-NNN: Title + behavioral description + pass/fail criteria + evidence requirements
• Add cross-area flows section
• Review 2x for gaps

Step 5: Features (.mission/features.json)

For each assertion, create a feature that fulfills it:

• id, description, milestone, preconditions, expectedBehavior, verificationSteps, fulfills, status
