Summary

This repo had no development workflow at all — no root package.json, no linter, no hooks, no CLAUDE.md or CONTRIBUTING.md. CODEOWNERS was the only process artifact. For a public repo meant for community contribution that is the real gap, and it also blocks dogfooding: the implement prompt instructs an agent to "follow CLAUDE.md and CONTRIBUTING.md exactly", and there was nothing to follow.

This is phase G1 of the extraction plan — unblocked and independent of C and D.

Three lanes, one runner

Lane What
lint eslint over packages/pipeline
invariants imports stay inside the package, resolve, and are dynamic-only
tests the 705-test suite

npm run verify:fast (pre-commit) and npm run verify:self (pre-push) run these, and CI runs the same lanes by name, one per job. The structural checks were previously inline shell in tests.yml, so a contributor could not run them before pushing and nothing kept that shell honest.

The arrangement is the interesting part

The suite must pass with node_modules absent — that is what enforces the dynamic-import rule, and a module-scope SDK import taking the whole suite down is the intended signal. But lint needs devDependencies. So:

  • eslint is a root dependency; packages/pipeline stays empty
  • CI keeps them in separate jobs; the tests job installs nothing
  • verify-invariants.mjs fails if an install appears in the job that runs the suite

That last one matters because a comment cannot hold the property. An npm ci added to the tests job for a plausible reason would leave every test passing while quietly retiring what the emptiness proves. Mutation-tested: adding an install fails the lane, and so does renaming --lane tests so the check would inspect nothing.

The linter never travelled with the code

It is wafflebase's config, re-scoped. Since the extraction, ~30 modules that decide whether a PR may merge have had no static analysis — only node --test, and only over paths a test happens to reach. It reports 61 files and zero violations; mutation-tested by re-planting #657's undeclared identifier (retryAt on the round-cap page path), which it names in milliseconds.

Also

  • Fixes finding #10 at last. packages/pipeline's own test script was the flat *.test.mjs glob that matches nothing in subdirectories. It was recorded in the audit, never applied, and npm test there has been silently skipping suites.
  • Two README corrections: it still listed auth-smoke among the untested scripts (it has had nine tests since D1), and the quickstart predated the lanes.
  • tests.yml's header now records why the name is not CI in extraction terms too: mark-ready.mjs and set-state.mjs still hardcode r.name === "CI", so this repo is the only place a non-default CI name is exercised at all. Renaming it would retire that.

Dropped deliberately

A fourth invariant — "no test reads a path outside the package" — was drafted and removed. A textual scan cannot tell readFileSync("../x") from "../../etc" used as a path-traversal test input, and capture-meta.test.mjs is full of the latter; it reported the tests that guard traversal as if they performed it.

Test plan

  • npm run verify:self green on a fresh clone: lint ✓, invariants ✓, tests 705/705
  • packages/pipeline/node_modules absent throughout
  • Every guard mutation-tested: planted undeclared identifier, module-scope third-party import, unresolved relative import, npm ci in the tests job, renamed test lane
  • tests.yml parses; hooks executable and core.hooksPath set by postinstall

Not in scope

G2–G4 (arming the pipeline on this repo's own PRs) need phase D to convert the workflows to workflow_call, and the loop verbs additionally need C1 to remove the hardcoded CI name. docs/adoption.md and friends land with D6's adoption kit.

Summary by CodeRabbit

  • New Features

    • Added automated verification for linting, tests, and structural project checks.
    • Added Git hooks to validate commit formatting and run checks before commits and pushes.
    • Added recursive test discovery with execution time limits.
  • Documentation

    • Added contributor and development guidance covering setup, verification, workflows, security, and release practices.
    • Updated the README with installation, verification, and test coverage information.
  • Chores

    • Added project configuration for package management, linting, and ignored dependencies.

It had none. No root package.json, no linter, no hooks, no CLAUDE.md or
CONTRIBUTING.md — CODEOWNERS was the only process artifact. For a public repo
meant for community contribution that is the actual gap, and it also blocks
dogfooding: the implement prompt tells an agent to "follow CLAUDE.md and
CONTRIBUTING.md exactly", and there was nothing to follow.

Three lanes, run by one runner so local and CI execute the same commands rather
than two copies. The structural checks used to be inline shell in tests.yml,
which meant a contributor could not run them before pushing:

  lint         eslint over packages/pipeline
  invariants   imports stay inside the package, resolve, and are dynamic-only
  tests        the 705-test suite

THE ARRANGEMENT MATTERS. The suite must pass with node_modules ABSENT — that is
what enforces the dynamic-import rule, and a module-scope SDK import taking the
whole suite down is the intended signal. Lint needs devDependencies. So eslint is
a ROOT dependency, packages/pipeline stays empty, and CI keeps them in separate
jobs. `verify-invariants.mjs` now fails if an install appears in the job that
runs the suite: a comment cannot hold that property, and an `npm ci` added there
for a plausible reason would leave every test passing while retiring what the
emptiness proves.

The linter is wafflebase's config, re-scoped. It never travelled with the code,
so ~30 modules that decide whether a PR may merge have had no static analysis
since the extraction. It reports 61 files and zero violations; mutation-tested by
re-planting #657's undeclared identifier, which it names in milliseconds.

Also fixes finding #10 at last: packages/pipeline's own `test` script was the
flat `*.test.mjs` glob that matches nothing in subdirectories. It was recorded in
the audit, never applied, and `npm test` there has been silently skipping suites.

Two README corrections: it still listed auth-smoke among the untested scripts (it
has had nine tests since D1), and the quickstart predates the lanes.

A fourth invariant — "no test reads a path outside the package" — was drafted and
dropped. A textual scan cannot tell `readFileSync("../x")` from `"../../etc"` used
as a path-traversal test INPUT, and capture-meta.test.mjs is full of the latter.
It reported the tests that guard traversal as if they performed it.

Review Change Stack

Warning

Review limit reached

@harrykim8672, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 42 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds a root verification runner, structural invariant checks, Git hooks, CI verification lanes, ESLint configuration, package metadata, and repository documentation for setup, security, contribution, and release practices.

Changes

Verification and contribution controls

Layer / File(s) Summary
Verification runner and commands
package.json, eslint.config.mjs, packages/pipeline/package.json, scripts/verify-self.mjs
Defines lint, invariant, test, fast, named-lane, and JSON verification commands. Tests use recursive discovery and a 60-second timeout.
Structural invariant checks
scripts/verify-invariants.mjs
Discovers pipeline modules and validates import boundaries, import resolution, module-scope dependencies, and workflow installation rules.
Hooks and CI integration
.githooks/*, .github/workflows/tests.yml, .gitignore
Runs verification through Git hooks and CI lanes. The commit-message hook enforces subject, separator, and body-line limits.
Repository setup and contribution guidance
CLAUDE.md, CONTRIBUTING.md, README.md
Documents setup, verification, security constraints, contribution rules, workflow requirements, release practices, and test coverage status.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🟡 Moderate · up to 759ae

The new development workflow can incorrectly approve repositories with invalid import behavior, while malformed lane arguments may run checks different from those requested and CI jobs retain checkout credentials unnecessarily. The PR is not merge-ready until these bounded correctness and security issues are addressed or explicitly accepted.

file, using statSync(target).isFile() while preserving the existing escape-path
and problem-reporting behavior.
- Around line 94-99: Update the import/export detection in the invariant scanner
loop to parse declarations lexically rather than relying on column-zero
indentation. Ensure leading whitespace is accepted, while comments and
fixture-string contents are excluded, and preserve collecting each detected
module specifier in out.

In `@scripts/verify-self.mjs`:
- Around line 92-103: Validate that --lane is followed by a non-empty value
before selecting lanes, and exit with an error for a missing value instead of
falling through to all lanes. Update the argument parsing around only and
preserve the existing unknown-lane validation and fastOnly behavior.

All four of CodeRabbit's findings on this PR reproduce as written; each
was mutation-tested before and after.

- `persist-credentials: false` on all three checkouts. No step in any job
  uses the token, so it does not need to sit in `.git/config` where the
  lint job's `npm ci` — the one place third-party code runs here — could
  read it.

- The module-scope import check anchored on column 0, and the comment
  said so outright. One leading space hid an `import { z } from "zod"`,
  and so did the same import spread over several lines; both passed the
  lane. It now keys on the declaration form, which is what actually makes
  an import module-scope, and keeps the fixture-string exclusion because
  an indented keyword now counts. Detection goes 256 -> 276 on this tree,
  all 20 genuine multi-line relative imports, none newly a problem.

- `existsSync` accepted a relative import that resolved to a DIRECTORY.
  ESM has no directory resolution, so that is a crash the lane called
  fine; it now requires a file.

- `--lane` with no value fell through to running EVERY lane — the loudest
  possible reading of a flag that asked for one — and in the tests job
  that means the lint lane in a checkout that installs nothing. It now
  errors, alongside the existing unknown-lane check.

Verified: all three lanes green, tests 705/705 with
`packages/pipeline/node_modules` absent, workflow parses, and the planted
mutations (indented import, multi-line import, directory target, plus the
column-0 / unresolved / escaping cases that already worked) each fail the
lane.
