What

Adds packages/tiny-engineer-cli (tiny-engineer bin): one CLI for robot control and IDE hook wiring (Cursor, Claude Code, Antigravity).

  • hook <ide> — stdin hook JSON → pose map → POST /anim
  • anim / play — direct robot calls (/anim, /play)
  • setup — merge hook configs into the project; optional .env URL
  • doctor — URL, token, hook wiring, /health
  • uninstall — remove only Tiny Engineer hook entries
  • Env: TINY_ENGINEER_URL, TINY_ENGINEER_TOKEN (+ project .env)
  • CI / docs hooks: npm test --prefix packages/tiny-engineer-cli

Replaces the need for separate per-IDE CLIs for the default path; REST remains for custom agents/scripts.

source: #64

Checks

  • Title is type(scope): summary
  • Packages: npm test --prefix packages/tiny-engineer-cli
  • No .env, tokens, or Wi-Fi passwords in logs or screenshots

Test plan

  • npm test --prefix packages/tiny-engineer-cli
  • node packages/tiny-engineer-cli/bin/tiny-engineer.js --help
  • tiny-engineer setup cursor --yes (or interactive) merges hooks; foreign hooks kept
  • echo '{"hook_event_name":"stop"}' | tiny-engineer hook cursor hits robot (or fails fast on missing robot)
  • tiny-engineer doctor reports URL / health / hook wiring
  • tiny-engineer uninstall cursor --yes removes only Tiny Engineer entries
  • Optional: smoke anim / play against a live robot

Summary by CodeRabbit

Summary

  • New Features
    • Added the unified tiny-engineer CLI to set up, remove, and troubleshoot Cursor, Claude Code, and Antigravity integrations.
    • Added commands to trigger animations and play audio, plus hook feedback that can identify files being edited.
    • Setup preserves existing configuration; uninstall can remove Tiny Engineer hooks and optionally clean up environment settings.
  • Documentation
    • Updated setup, integration, REST API, and migration guidance, including the CLI’s separate npm release process.
    • Marked dedicated IDE-specific CLI packages as deprecated and provided migration guidance.
  • Chores
    • Added CLI package tests to automated and documented test checks.

📝 Walkthrough

Walkthrough

The PR adds a unified CLI for Cursor, Claude Code, and Antigravity. It supports hook processing, setup and removal, animation and audio playback, and diagnostics. Repository hook configurations, package metadata, tests, and documentation now reference the unified CLI.

Inline comments:
Review comments at @packages/tiny-engineer-cli/src/cli.js:
- Around line 103-104: Bound non-TTY reads in readStdin with a short timeout
that resolves using the input collected so far, allowing the hook to continue
when stdin remains open. Clear the timeout when stdin ends or errors, and
preserve the existing empty result for TTY input; keep this timeout separate
from the network timeout around postAnim.
- Around line 109-126: Update the `hardExitAfterPost` exit path in the CLI so
pending stderr output is flushed before `process.exit(0)`. Preserve the existing
condition and exit behavior, waiting for stderr to drain only when output is
pending.

Review comments at @packages/tiny-engineer-cli/src/wizard/cliPath.js:
- Around line 13-21: Update the tarball-based npx setup flow to pass a stable
npx launcher as the command used by `hookCommandFor()`, rather than persisting
the CLI path in the npx cache. Preserve `hookCommandFor()`’s absolute-path
default for local installs.

Review comments at @packages/tiny-engineer-cli/src/wizard/setup.js:
- Around line 226-228: In setup, check whether the config file exists when
readJsonFile(abs) returns null; report the invalid JSON, set a failing exit
code, and return before calling integration.applyInstall or writeJsonFile. Leave
uninstall behavior unchanged.

Review comments at @docs/cli-release.md:
- Line 12: Update the CLI tag example in the release documentation table to
match the documented release version: use cli-v0.1.1 or a cli-v<version>
placeholder, consistent with the tiny-engineer package version.

Review comments at @packages/tiny-engineer-cli/src/util/stdin.js:
- Around line 20-24: Update readStdin’s finish function to remove the data, end,
and error listeners from the stream whenever the promise settles, including on
timeout, normal completion, and errors. Reuse the listener references registered
by readStdin so repeated calls do not leave listeners or retain their chunks
arrays.
