C Catann

Constraints (must follow)

• Only run this skill when explicitly instructed by the user.
• Only edit files under firegame/app/firegame/src/routes/catann/app/gameLogic.
• You may also edit test/choreo.ts, but you may not add imports.
• If a required change is outside those locations, stop and report what you need to change instead of editing.
• Never manipulate __socketCatannMessages
• Game-logic edits must be done one at a time (single focused change per run). Choreography additions can be batched.

Notes

• Always follow firegame/.codex/skills/s_catann/SKILL.md for the test workflow.
• Keep firegame/.codex/skills/c_catann/AGENTS.md updated with new choreography knowledge.
• Debug flow to keep in mind: iframe -> handleMessage -> parseClientData -> applyGameAction -> setFirebaseData -> FirebaseWrapper diff -> sendToMainSocket -> iframe.

Time constraint default

If no time constraint is provided, keep iterating and updating test/choreo.ts until the test passes or until the second time you need to change gameLogic. At that point, stop and report what remains.

Known choreography expectations

• The test compares recorded socket message bytes after filtering heartbeats.
• The choreography should drive the UI through click interactions only.
• In responses, lead with the console.log({ codex: ... }) object from both the first and final runs, on seperate lines.
