Skill: catann

Always prepend the { codex: { ... } } object from the test output (if it appears) to the final response, and then include the screenshot (if screenshot.png exists) as the first visual part of the final response, even when the test fails. Always include the full test_catann.sh output in the final response. The output can include ANSI color codes; when presenting it, render a human-readable version with ANSI removed (plain text).

Summary flow

1. Start the dev server (keep it running).
2. Run tests and capture output.
3. Collect screenshot.png (if present).
4. Host the image locally and attach it.
5. Report results + full logs.

Pre-commit validation

Before committing changes, validate TypeScript by running:

bash
1cd firegame/app/firegame
2yarn lint
3yarn tsc --noEmit

Then validate the regression catann suite specifically:

bash
1cd firegame/app
2CATANN_REGRESSION=1 timeout 300s bash ./test_catann.sh --codex

Regression mode is enabled via CATANN_REGRESSION=1; only regression-mode choreos execute when this env var is set.

If either command fails (including duplicate/overwritten property diagnostics such as TS2783), fix the issue and rerun until both pass. Treat this as the authoritative typecheck gate before continuing with test runs or commits.

Anti-slop change validation (required)

Before committing any non-trivial Catann change:

1. Stage the intended patch and inspect the full diff.
2. Identify suspicious additions (extra helpers, hardcoded branches, test-only magic values, broad refactors) and explicitly test whether each is necessary.
3. Prefer the simplest implementation with the smallest diff that preserves behavior.
4. Re-run the workflow and compare the resulting { codex: ... } printout to confirm no regression.

If removing a new abstraction/helper yields the same behavior, do not keep it.

Timestamp format (NYC time)

At the start of each numbered step, record a timestamp in America/New_York using:

bash
1TZ=America/New_York date "+%Y-%m-%d %H:%M:%S %Z"

Include the raw command output in your notes/output for that step.

1) Start the dev server (keep running for hot reloads)

bash
1cd firegame/app/firegame
2yarn start

Keep this command running.

2) Run tests and capture output

In another shell:

bash
1cd firegame/app
2timeout 300s bash ./test_catann.sh --codex

If the timeout is hit, report it as a failure and proceed to collect the screenshot (if available).

If CODEX_HOME is not set, omit --codex so test_catann.sh can start the server for you.

Fix mode (only if explicitly requested)

If the prompt explicitly requests, fix the failing test and rerun the Catann workflow until it passes. For a solution, are only allowed to change files in firegame/app/firegame/src/routes/catann/app/gameLogic. Do not stop after a single failing attempt or timeout; keep re-running the test command after each fix until you get a clean pass. Once it passes, continue with the screenshot steps. Follow AGENTS.md in the same folder as this skill doc. Do not introduce global variables, global state, or manipulate the DOM or window objects.

Game-logic purity guard

When editing app/gameLogic, keep logic explicitly game-behavior driven. Avoid hardcoded test fixtures, magic IDs, lookup tables for recorded runs, or special-case branches that exist only to satisfy a single capture.

If test data is required, consume values that the harness already provides via existing override paths rather than encoding constants in game logic.

3) Locate output image (if present)

bash
1cd firegame/app/firegame/test-results
2ls
3# pick the folder just created, then:
4cd <test-results-subfolder>
5ls
6# expect: screenshot.png

4) Host image locally (for browser pickup)

bash
1python -m http.server -b 0.0.0.0 8001

5) Screenshot capture (browser tool / Playwright)

If a browser tool is available, open http://localhost:8001/screenshot.png and include it in the response. If no browser tool is available, still mention whether screenshot.png was found and hosted. Ensure the screenshot capture waits for network idle (e.g., use a browser tool's equivalent of Playwright's wait_until='networkidle') before attaching the image.
