Summary

Removes the reference extension/ folder from this repository and points every living reference at bQuery/devtools-extension, where the DevTools browser extension has been rebuilt in TypeScript.

User-facing impact: none at the API level. Nothing under src/ changes behaviourally — @bquery/bquery/devtools still exports the same stable bridge protocol (connectDevtoolsBridge, createBridgeServer, BRIDGE_PROTOCOL_VERSION v1). The only change to src/ is a doc comment. Readers following the devtools guide are sent to the new repository instead of a folder that no longer exists.

This is phase 6 of the extraction; phases 1–5 are bQuery/devtools-extension#1.

Motivation

Closes #205.

  • Separate lifecycles — the extension is gated by browser-store review, not by the npm release train.
  • Protocol as contract — the bridge was stabilised in 1.15 precisely so an external consumer could prove it. It now has one.
  • Repository hygieneextension/ was ~330 lines of untyped vanilla JavaScript with no build, tests, linting or packaging, shipped from a repo whose every other line is strict TypeScript under test.

Changes included

Removed

  • extension/ (8 files: manifest, background worker, content script, devtools page, panel, README).

Living documentation → new repository

  • docs/guide/devtools.md — the Stable exit-criteria checklist, the "load the extension" instructions (now: clone, bun run deploy-v3, load dist/), and the version-history entry.
  • docs/introduction.md, README.md module table, AGENT.md, llms.txt.

Historical records — kept accurate, not rewritten

  • The 1.15.0 CHANGELOG entry and docs/release-notes/1.15.md still state the extension shipped in extension/, because it did. What changed is the dead tree/main/extension hyperlink, replaced with a note that it has since moved — lychee checks docs/**, so leaving it would have gone red.
  • The removal itself is recorded under CHANGELOG Unreleased.

No public API, behaviour, or workflow changes.

Validation

  • bun run lint — clean, no files rewritten
  • bun run build — ESM + UMD + IIFE + declarations
  • bun test — 3067 pass, 1 fail: server/createServer > returns a valid URL for IPv6 node listen addresses, which is EADDRINUSE on IPv6 in the sandbox. Pre-existing — I confirmed it fails identically on the pristine tree with my changes stashed, and a documentation-only diff cannot reach src/server/create-server.ts.
  • Additional focused checks:
    • bun run checkcheck:ai-guidance, check:full-bundle, check:stability, check:doc-exports all pass. The guidance sentence was kept byte-identical across AGENT.md and llms.txt so the sync check stays satisfied.
    • bun run lint:types — clean.
    • bun run format:check — clean repo-wide (my README table edit changed the column widths; re-formatted with the repo's own Prettier).

Checklist

  • I followed the contributing guidelines.
  • I added or updated tests where behavior changed. — No behaviour changed; the removed folder had no tests, and the extension's own suite (153 unit + 9 E2E) lives in the new repository.
  • I updated documentation when public behavior or developer workflow changed.
  • I confirmed the change does not introduce security-sensitive regressions.

Notes for reviewers

  • Merge order matters. Please don't merge this before feat: rebuild the bQuery DevTools extension on BrowserExtensionTemplate devtools-extension#1, or the docs will point at a repository with no extension in it for as long as the gap lasts.
  • Deliberate judgment call worth checking: I edited the 1.15 release notes and left the 1.15 CHANGELOG entry alone. My reasoning is that release notes describe what shipped and shouldn't be retconned — only the broken link needed fixing. If you'd rather have the historical records fully rewritten (or fully untouched, accepting one dead link), say so and I'll adjust.
  • .github/copilot-instructions.md mentions a "reference extension" in its 1.15 release narrative with no path. I left it: it's historical prose, and it's one of the files check:ai-guidance compares.
  • The new repository's protocol module pins this repo's contract via typeof import('@bquery/bquery/devtools') type queries, so a future BRIDGE_PROTOCOL_VERSION bump here surfaces there as a compile error rather than a silent runtime mismatch. Worth knowing before the next protocol change.

Summary by CodeRabbit

  • Documentation

    • Updated DevTools documentation, release notes, and module references to point to the separately released browser extension.
    • Clarified that the DevTools bridge protocol remains stable and unchanged.
  • Removed

    • Removed the in-repository browser extension and its bundled setup and usage instructions.
    • The browser extension is now maintained and released separately, with no changes to runtime behavior.

The reference `extension/` folder was ~330 lines of untyped vanilla
JavaScript with no build, tests, linting or packaging. It now lives in
bQuery/devtools-extension, rebuilt in TypeScript on BrowserExtensionTemplate,
so it can follow browser-store review cycles instead of the npm release train.

Nothing under `src/` changes behaviourally: `@bquery/bquery/devtools` still
exports the same stable bridge protocol (`connectDevtoolsBridge`,
`createBridgeServer`, `BRIDGE_PROTOCOL_VERSION` v1). That protocol is now
proven by an external consumer, which is what it was stabilised for in 1.15.

- Remove `extension/`.
- Point the living docs at the new repository: the devtools guide (exit
  criteria, "load the extension" instructions, version history), the
  introduction, README module table, `AGENT.md` and `llms.txt`.
- Keep the historical 1.15 records accurate rather than rewriting them: the
  CHANGELOG entry and `docs/release-notes/1.15.md` still say the extension
  shipped in `extension/`, with the dead tree link replaced by a note that it
  has since moved.
- Record the removal under CHANGELOG "Unreleased".

Closes #205

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 7edaf

This PR redirects DevTools users to the external extension repository; merging it before that repository contains the replacement could temporarily leave users without an available extension. The change is otherwise localized, so it is mergeable with explicit merge-order awareness.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Make the external extension available before merging, or gate these references.

This PR removes the tracked extension/ directory and points the DevTools guide and related living documentation at bQuery/devtools-extension, but the supplied repository state is not yet public and does not contain the published implementation. Merging now would leave users directed to unavailable setup material. Publish the extension first, or update the availability and setup claims until the external repository is ready.

Substantively right, and I am deliberately not changing the docs for it. Leaving this thread open, because it is a live merge blocker rather than something a commit here can close.

One detail corrected: the repository is not missing — bQuery/devtools-extension exists and its CI is running. What it does not yet have on main is the implementation, because that lives in bQuery/devtools-extension#1, which is green and awaiting merge. So the consequence you describe is real: merge this today and the DevTools guide sends readers to a repository holding a template and workflows, not an extension.

The resolution is ordering, not wording. It is stated in this PR's description ("Merge order matters"), and the maintainer has set the sequence explicitly:

  1. ci: remove the superseded legacy CodeQL workflow devtools-extension#2 — legacy CodeQL workflow removed ✅ merged
  2. feat: rebuild the bQuery DevTools extension on BrowserExtensionTemplate devtools-extension#1 — the extension itself ⏳ green, awaiting merge
  3. this PR ⏳ last

Hedging the availability claims instead would mean writing text that is wrong the moment step 2 lands, then reverting it — churn that makes the history harder to read, for a window that is measured in minutes. The links are correct for the state this PR is meant to be merged into.

If step 2 were abandoned rather than merged, this PR should be closed rather than reworded, so the hedge would never be the right fix in either branch of that decision.

@JosunLP, thanks for the clarification.

Verification confirms that bQuery/devtools-extension#1 is open, clean, and unmerged. Its diff contains the bQuery DevTools implementation. The main branch still contains the BrowserExtensionTemplate implementation.

The finding remains a merge-order blocker. No documentation change is necessary if this PR merges only after bQuery/devtools-extension#1.

Learning: For bQuery/bQuery pull request `#207`, the external `bQuery/devtools-extension` repository exists, but the bQuery DevTools implementation is introduced by `bQuery/devtools-extension#1`. Pull request `#207` must merge only after that pull request merges; temporary documentation hedging is not required.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

You are interacting with an AI system.

CodeRabbit is right: this pull request does touch `src/` — the module
comment in `src/devtools/index.ts` now points at the new repository. The
entry claimed otherwise, which would have been misleading to anyone
diffing the release.

Says what is actually true instead: no runtime behaviour changed, and the
single edit under `src/` is that doc comment. The API and bridge-protocol
details are unchanged.
