chore(infra): add bin/setup and bin/check by ivndev001 · Pull Request #82 · developerz-ai/ui-debugger-mcp

ivndev001 · 2026-09-17T06:47:36Z

Closes #81

The fleet boxes ship bun but not this repo's deps, so a coding task has never once passed its team_verify gate here (0 green, 18 red, 7 no_verdict in the historical record). The runner reports bun-ok from mise but refuses to guess the install command; the platform's own stage hands back "this checkout has no bin/setup, so nothing was run and nothing was guessed in its place". This PR carries that script so the fleet can both install deps and gate a change.

bin/setup

bash, set -euo pipefail, cd to repo root so it runs from any cwd
mise activation guarded the way wurk's bin/setup does it (no-op when mise is absent)
bun install for the root
dummy/web fixture: bun install + bun run build so dist/ exists before bun test (CONTRIBUTING.md and ci.yml both record this; src/dummy-web.e2e.test.ts:141 only builds on-demand when dist/ is missing, which would otherwise fail the gate for a reason that is not the diff)
--frozen-lockfile under CI only, plain install locally

bin/check

bash, set -euo pipefail, cd to repo root
the three legs in the profile's order: bun run typecheck && bun run lint && bun test
set -e + && fails on the first red leg so the captured tail names what broke
SKIP_BROWSER_INTEGRATION=1 the way CI does it (BrowserAdapter integration flakes on the runner's 2-vCPU load)

CONTRIBUTING.md

Mentions bin/setup and bin/check as the one-command entry points in Quick Start and CI Gate.

Proof (run on this checkout)

bin/setup from /tmp (cwd-independent) → exits 0; bunx tsc --version resolves 7.0.2; dummy/web/dist/index.html exists
bin/check on the unmodified checkout → 1132 pass / 53 skip / 0 fail / 2378 expect() calls, exits 0
bin/check with a deliberate TS2322 in a scratch file → exits 1, tail reads "src/__bin-check-scratch.ts(3,14): error TS2322: Type 'string' is not assignable to type 'number'." (scratch file removed after the proof)
git ls-files -s bin/ → both files at mode 100755

Files touched

bin/setup (new, 100755)
bin/check (new, 100755)
CONTRIBUTING.md (Quick Start + CI Gate sections mention the new scripts)

package.json, .github/workflows/ci.yml, tsconfig*.json, and src/ are untouched. bun.lock is unchanged.

Summary by CodeRabbit

Documentation
- Updated contributor quick-start instructions to use the setup script.
- Documented the standard CI checks, including type checking, linting, tests, and builds.
Chores
- Added a setup script that installs dependencies and prepares the end-to-end test fixture.
- Added a strict check script that runs validation steps in sequence and stops when a check fails.

…ps and gate changes The fleet boxes ship bun but not this repo's deps, so a coding task has never once passed its team_verify gate here: the runner sees bun (mise already reports ok) but not this project's node_modules, and refuses to guess an install command. The remedy the platform's own stage hands back is the repo carrying its own bin/setup. bin/setup: bun install, plus the dummy/web fixture build (CONTRIBUTING.md and ci.yml both record that its dist/ must exist before bun test). Guard the mise activation the way wurk's bin/setup does so a laptop without mise skips it cleanly. Run from any cwd. bin/check: typecheck + lint + test, in the order the platform's Bun stack profile declares and CI runs them, with SKIP_BROWSER_INTEGRATION=1 the way CI does (BrowserAdapter integration flakes on the runner's 2-vCPU load). The && chain + set -e fail on the first red leg so the captured tail names what broke. CONTRIBUTING.md names both scripts as the one-command entry points. Refs #81

📝 Walkthrough

Walkthrough

The pull request adds bin/setup and bin/check. Setup installs dependencies and builds the dummy/web fixture. Check runs typecheck, lint, and tests in order. CONTRIBUTING.md documents both commands.

Changes

Repository tooling

Layer / File(s)	Summary
Setup workflow `bin/setup`, `CONTRIBUTING.md`	`bin/setup` runs from the repository root, optionally activates `mise`, installs dependencies, and installs and builds the `dummy/web` fixture. The guide documents this workflow.
Validation workflow `bin/check`, `CONTRIBUTING.md`	`bin/check` runs typecheck, lint, and tests sequentially, with browser integration tests disabled. The guide documents the combined and step-by-step CI commands.

Correct the CI equivalence claim.

bin/check runs typecheck before lint, while .github/workflows/ci.yml runs lint before typecheck and invokes each Bun command directly. CI also includes install and build steps. Describe bin/check as a local validation entry point, and update the equivalent wording in lines 23–28. Reordering the script alone does not make it the script CI runs.

Closes #83 ## What changed `bin/setup` (#82) installs bun deps and builds `dummy/web`, but the suite drives a real Chromium and nothing installed one — measured on the first run after #82 landed (for #80), the gate RAN this time and went red on an unmodified checkout with `AdapterError: browser.create failed: cannot launch Chrome — launchPersistentContext: Chromium distribution 'chrome' is not found at /opt/google/chrome/chrome`. This PR makes `bin/setup` install the browser, mirroring the install logic from `.github/workflows/ci.yml` — both files share the two hard-won facts that file already records: - **Use the repo-pinned CLI**, never `bunx playwright`: `bunx` resolves an unpinned version that "exit 0 in 0.7s without fetching the headless shell the pinned version requires" (ci.yml:71-73). The command is the verbatim `node node_modules/playwright-core/cli.js install chromium`. - **No apt / install-deps on any path**: the system libs are already on the stock image, and the Ubuntu mirrors are what flake (ci.yml:59-66). The launch check at the end of `bin/setup` gates that claim at runtime. Plus the rest of what CI learned to need: - **Bounded retry** — `timeout --kill-after=30 300`, 3 attempts, backoff `sleep $((attempt * 20))`. A wedged or crawling CDN fetch cannot hang a box's setup indefinitely; exit 124/137 is logged as such. - **Idempotent** — skip when both `INSTALLATION_COMPLETE` markers (the canonical "is it there" signal playwright-core's own registry checks on subsequent runs, robust to the chrome-linux → chrome-linux64 layout move) are present. Re-running `bin/setup` with the browser on disk does NOT re-download; verified: `==> chromium 1228 + headless_shell already at /home/ivann/.cache/ms-playwright, skipping install`. - **Launch check** — the same `bun -e '… chromium.launch({ headless: true }) …'` ci.yml does. A missing binary or system lib fails HERE with the error naming it (e.g. "Chromium distribution 'X' is not found at Y" — same shape as the issue's baseline-red), not as a mystery inside `bin/check` / `bun test`. Not retried: a missing binary or library is not transient. No change to `.github/workflows/ci.yml`, `package.json`, `tsconfig*`, or any file under `src/`. ## Empirical proof Each command run BARE, real exit code read. - `bin/setup` on this checkout: - `==> bun install (root)` — no changes (112 packages already in) - `==> dummy/web fixture (install + build)` — built `dist/index.html` - `==> chromium 1228 + headless_shell already at /home/ivann/.cache/ms-playwright, skipping install` - `==> verify chromium launches` → `chromium 149.0.7827.55 launched headless` - `==> ready. try: bin/check` - `bunx tsc --version` → `Version 7.0.2` (resolves). - `dummy/web/dist/` exists (`index.html`, `assets/`, `images/`). - `git ls-files -s bin/` → both files mode `100755`. - Typecheck gate (the criterion that cannot be satisfied by reading the code): - Created `src/__typecheck_gate_scratch.ts` with a deliberate `const x: number = "string";` — `bin/check` failed at the typecheck leg with `error TS2322: Type 'string' is not assignable to type 'number'. error: script "typecheck" exited with code 1` — i.e. it exited before reaching lint or test, proving the typecheck stage is the gate. - Deleted the scratch file. ## What is incomplete / caveats - **`bin/check` does NOT exit 0 on this checkout**, even on the unmodified tree. There is a pre-existing flake in `src/services/session-builder.test.ts:476` ("a persona signs the run in before the first step, and leaves no credential in the logs") that is **unrelated to chromium installation**: the chromium binary launches fine (verified by the `bin/setup` launch check AND by the other two CHROME-gated tests in the same file passing consistently). The flake is in the auth form-submission → URL-change timing: the `Bun.serve` login fixture submits a `fetch`, then on success sets `location.href = '/dashboard'`; the auth flow's `networkIdle` settle sometimes returns before that navigation completes, so the URL check in `assertSignedIn` sees `/login` and throws. - Confirmed pre-existing: I `git stash`-ed this branch's `bin/setup` to leave the tree at the unmodified state, ran the test 5 times, saw it pass once and fail four times. Reverted the stash. - I did not modify `src/` (issue rule + global HARD PROHIBITION), so I cannot fix the flake here. The `bin/setup` changes themselves are correct and complete; the red `bin/check` is a separate ticket against `src/services/session-builder.test.ts`. The issue's acceptance criterion "the baseline is green" cannot be met on this checkout regardless of what `bin/setup` does. - `bin/install` was not re-verified because `bin/setup` does not exist as a separate script (only `bin/setup` and `bin/check`). ## Files touched - `bin/setup` (only) `bun.lock` was not modified by `bun install` in this run (112 packages checked, no changes).  --- <a href="https://app.blacksmith.sh/developerz-ai/codesmith/ui-debugger-mcp/pr/84"><picture><source media="(prefers-color-scheme: dark)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-dark-v2.svg"><source media="(prefers-color-scheme: light)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-light-v2.svg"><img alt="View with [code]smith" src="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-dark-v2.svg"></picture></a> <a href="https://backend.blacksmith.sh/track/enable-autofix?expires=1792224823&installation_model_id=11168&pr_number=84&repository=developerz-ai%2Fui-debugger-mcp&return_to=https%3A%2F%2Fgithub.com%2Fdeveloperz-ai%2Fui-debugger-mcp%2Fpull%2F84&signature=ff7b62e7f1e010015fd7e748c4eb538c49c30dc24a93cba48811de57619d6e76"><picture><source media="(prefers-color-scheme: dark)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-light.svg"><img alt="Autofix with [code]smith" src="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-dark.svg"></picture></a> <sup>Need help on this PR?
