GOAL

Implement the game described in flashmania_description.md as a working TypeScript browser game, working around a repository whose existing files had already been deleted.

  1. Prompt · +0
    Implement the game described in flashmania_description.md in TypeScript.
  2. Agent did · +0
    Inspected repo, read flashmania_description.md, then found via git status that nearly all existing project files (package.json, src/*.ts, dist/*) were already deleted in the working tree.
  3. Fail · +0
    Agent stopped, unsure whether to recreate deleted app files, preserve deletions and add new paths, or restore tracked files first — asked for direction instead of guessing.
  4. Agent did · +0
    On goal continuation, agent decided to avoid touching the deletions and built a standalone TypeScript game under flashmania-game/ (Vite setup, canvas game loop, car physics, checkpoints, ghost replay, WebAudio, README), then snapshotted progress.
  5. Agent did · +0
    Re-read the generated README and main.ts, grepped for key mechanics (surfaces, pads, medals, ghost, finish/checkpoint logic) to audit implemented requirements against the description before marking the todo complete.
  6. Agent did · +0
    Called complete_goal; goal marked complete with build verified via npm build in flashmania-game/, delivering main.ts, index.html, style.css, README.md and package.json.
  7. Prompt · +0
    How to start the game?
  8. Outcome · +0
    Session ends with a completed standalone TypeScript game in flashmania-game/, buildable via npm run build and runnable via npm run dev, plus follow-up Q&A on controls (throttle: Arrow Up/W).
VERDICT

Next time I'd start by telling the agent up front that the repo has a dirty worktree with deleted files, so it doesn't burn a turn getting blocked and asking me to choose a recovery path. The move that actually worked was building the game in a fresh flashmania-game/ subdirectory instead of touching the deleted root files — that sidestepped the ambiguity entirely and let it finish the implementation and self-audit cleanly.
