fix: list and count extension-type integrations when a live IDE bridge serves them - #1236
fix: list and count extension-type integrations when a live IDE bridge serves them#1236ralphstodomingo wants to merge 7 commits into
Conversation
…e serves them
The CLI presented extension-type integrations as categorically unusable
("not available from the CLI"). That is stale: with VS Code and the
Altimate extension open on the project, the workspace engine discovers the
bridge, allowlists the extension tools into the session, and serves them —
verified end to end (compile + warehouse materialization) on 2026-09-03.
- `datamate_manager list-integrations`: with a live bridge for the project,
list extension-type rows, mark them "(via VS Code)" and count them;
without one, keep them omitted but say they serve while VS Code with the
Altimate extension is open on this project — a state, not an impossibility.
- Attach announcement: append "Plus N extension tools via the connected VS
Code window" when the bridge is serving them. Absent extension tools stay
unwarned — that is the normal no-IDE case, never `missing`.
- New `liveBridge()` probe in engine-probes: a read-only mirror of the
engine's sidecar discovery (cwd prefix match, else the sole live bridge);
dead pids are skipped, never GC'd — stale-sidecar cleanup stays with the
engine and the extension.

For each claim, attempt to falsify it with concrete evidence from this diff (file + line); a claim that survives needs no comment. Findings already covered by a recorded residual are known — only raise one if you can show its impact is materially worse than recorded. Anything outside the claims/residuals map is fair game, but verify it empirically against the diff before reporting; no speculative or style-only findings. |

When altimate-code is launched from a subdirectory of a Git worktree, this passes the Git root to liveBridge(), while the MCP process is spawned with Instance.directory as its cwd (src/mcp/index.ts:560-566). If VS Code opened that subdirectory and another live bridge also exists, the sidecar matches the engine's actual cwd but not the Git root, disabling the sole-bridge fallback and causing extension integrations to be hidden even though the engine connects to them. Pass Instance.directory here so the presentation probe mirrors spawn-time discovery.
Useful? React with 👍 / 👎.

Confirmed and fixed in 1e44c32. Verified the premise before changing: connectLocal spawns with InstanceState.directory as cwd and the overlay's engine entry sets no cwd override, so the engine's discovery matches against the instance directory — the probe now uses the same input. C3 in the description should be read as algorithm and input; thanks for catching the input half.
`connectLocal` spawns the engine with the instance directory as its cwd, so discovery matches against that — not the Git root `projectRoot()` returns. Launched from a subdirectory with two live bridges, the probe declined (no cwd match, fallback refused) while the engine connected.

Resolve symbolic links before testing workspace containment.
liveBridge uses resolve(), which does not resolve symbolic links. A cwd symlink below a recorded workspace folder can point outside that folder and still pass the containment check. Canonicalize both paths before comparison and add a symlink regression test.

Bun test runner default concurrency are tests within a test file run in parallel official documentation
💡 Result:
By default, the Bun test runner executes tests sequentially within each test file [1][2][3]. Tests are run in definition order, and only one test within a file will execute at a time unless you explicitly opt in to concurrent execution [1][3]. To enable concurrent execution of tests within a file, you have several options: - Using the --concurrent CLI flag: This treats all tests in your files as concurrent by default, unless they are explicitly marked with test.serial [1][2][4]. - Using test.concurrent or describe.concurrent: You can mark individual tests or groups of tests to run concurrently, even without the --concurrent flag enabled globally [1][2][5]. - Using concurrentTestGlob in bunfig.toml: This allows you to enable concurrent execution for specific test files that match a given glob pattern [6]. When concurrent execution is enabled, Bun runs asynchronous tests in parallel, allowing them to overlap while waiting for I/O operations [1][2]. You can control the maximum number of tests running simultaneously using the --max-concurrency flag, which defaults to 20 [1][7][4]. Note that concurrent tests within a file share the same process and global state, providing cooperative concurrency rather than running on separate CPU cores [2]. To run entire test files in parallel across different CPU cores, you should use the --parallel flag instead [1][2].

Serialize tests that mutate the shared harness.
When Bun enables concurrent tests, install() mutates process-global syncInternals and process.env.ALTIMATE_WORKSPACE; afterEach cleanup does not prevent overlap. Mark this suite serial or isolate the harness to prevent cross-test contamination.

When an unbound instance adds the shared datamate key through POST /mcp with a local config containing cwd, this can report a bridge that the engine cannot use. The route forwards the validated config unchanged (packages/opencode/src/server/routes/mcp.ts:57-75), while connectLocal resolves the child cwd from mcp.cwd (packages/opencode/src/mcp/index.ts:555-566). For example, with the instance in a Git subdirectory, cwd pointing to a sibling, and two live sidecars including one for the instance directory, this new probe returns true although the spawned engine matches neither bridge and cannot use the sole-bridge fallback; the prior Git-root probe did not match that nested sidecar. Resolve the configured local entry's effective cwd instead of unconditionally probing Instance.directory.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
Confirmed and fixed in b56be7d. The probe now resolves the shared key's effective entry via a new MCP.entry accessor (exposing the connect path's own getMcpConfig precedence — runtime-added entries win over file config) and mirrors connectLocal exactly: a local entry's cwd resolved against the instance directory, else the instance directory. No entry / no runtime falls back to the instance directory, which is connectLocal's default too.

WARNING: extServed is not part of the announcement dedup signature, so a served-extension count change can be silently dropped.
The message now appends describeExtensionServed(extServed), but the rec.announced signature (line 666) keys only on workspace.key, outcome.available, outcome.declared, and missing. If an extension tool is replaced by a non-declared engine tool (or vice versa) while available, declared, and missing stay constant, if (rec.announced === signature) return suppresses the recomputed count and the "Plus N extension tools" clause goes stale. Fold extServed into the signature so the toast stays current.

…wd (review round) Review-round fixes from codex r2, CodeRabbit, kilo and cubic: - Probe with the cwd the engine is actually spawned with: `MCP.entry` (new, exposing the connect path's own config precedence) resolves a local entry's `cwd` against the instance directory, mirroring `connectLocal` exactly; falls back to the instance directory. (codex) - Validate the sidecar's folders shape: a non-array degrades to a folderless live bridge instead of throwing out of the probe and breaking the whole listing. (coderabbit, cubic) - ".." only counts as a complete path component: a child literally named "..cache" is inside the workspace folder. (cubic) - A recorded pid must be a positive integer to be probed — kill(0) and kill(-1) signal process groups and would read garbage pids as alive. (cubic) - Include `extServed` in the attach-announcement dedup signature so an equal-count tool swap that changes only the extension share still re-announces.

When a readable sidecar contains a nonnumeric pid such as "1234", null, or an object, this condition skips validation entirely and treats the record like a legitimate pid-less sidecar. With that as the sole record, the fallback at the end of liveBridge() returns true for any cwd, so list-integrations can advertise extension integrations from a malformed or stale sidecar. Distinguish an absent pid from a present-but-invalid one and reject the latter.

Confirmed and fixed in 179e433: a present pid now must be a positive live integer — string/null/object pids are corrupt records and disqualify the sidecar. Absent pid stays live for engine parity.

The new shape filter accepts empty and relative strings even though they are not valid recorded workspace-folder paths. within() subsequently resolves them against the altimate-code process cwd, so with two otherwise unrelated live sidecars, a malformed entry such as workspaceFolders: [""] spuriously matches whenever the probed cwd is the process cwd or one of its descendants. Filter folder values to nonempty absolute paths so malformed data cannot bypass the two-bridge ambiguity check.

Confirmed and fixed in 179e433: folder entries are filtered to nonempty absolute strings, so resolve("") can no longer alias the process cwd or defeat the two-bridge decline. Test covers the exact two-sidecar scenario.

- A present pid must be a positive live integer: the bridge extension
always writes one, so a string, null, or object pid is a corrupt
record — and unlike the engine, the probe has no connection attempt
behind it to catch a bad guess. Absent pid stays live (engine parity).
- Folder entries must be nonempty absolute strings: resolve("") is the
process cwd, so an empty or relative entry could spuriously match and
bypass the two-bridge decline.

Declined, with evidence. (1) MCP.entry runs through the same makeRuntime bridge the workspace overlay has used at every turn boundary since #1167 (MCP.status/MCP.add) — its runtime shares the app-wide layer memoMap (run-service.ts:52), so it resolves the SAME MCP service instance the session already built, not a second one. (2) This tool only executes inside a session turn, and the session's tool catalog has already called MCP.tools() — the per-instance state (and its server bootstrap) is initialized before any tool can run, so there is no 'before the user connects anything' window this call could open. (3) getMcpConfig reads instance state + merged config only; it spawns and connects nothing. (4) A failure cannot make the listing fail: engineSpawnCwd catches and falls back to Instance.directory (connectLocal's own default).

On Windows, a malformed sidecar containing a folder such as \ or \repo still passes this new filter: Node considers it absolute, but resolve() supplies the process's current drive. With two live sidecars, \ consequently matches every probed cwd on that drive and bypasses the intended two-bridge decline. The fresh evidence in this revision is the reliance on isAbsolute alone; require a fully qualified drive or UNC path before matching.
Useful? React with 👍 / 👎.

Confirmed and fixed in a87dd0b: folder entries now require a fully qualified path — drive-qualified (C:\ / C:/) or UNC on Windows, plain absolute on POSIX — via a platform-parameterized qualifiedFolder() so both branches are exercised in tests.
isAbsolute("\repo") is true on win32, but resolve() completes a
drive-relative path with the process's current drive — a corrupt sidecar
entry could match any cwd on that drive and defeat the two-bridge
decline. Folders now require a drive-qualified or UNC prefix on Windows;
POSIX keeps plain isAbsolute.

On Windows, the new UNC alternative accepts any string beginning with two backslashes, including incomplete pseudo-UNC values such as \\ or \\server. Node does not recognize these as UNC devices, so path.resolve() supplies the drive from process.cwd() (for example, producing C:\server); with two live bridges, such a corrupt folder can therefore still spuriously match a cwd on that drive and bypass the ambiguity check. The fresh evidence in a87dd0bbe is that the replacement regex checks only the two-character prefix rather than requiring nonempty server and share components.

Confirmed and fixed in 098bed8 — verified the premise first: win32.resolve("C:\\cur", "\\\\") is C:\\ and resolve("C:\\cur", "\\\\server") is C:\\server, the current drive again. The UNC alternative now requires nonempty server AND share components, with the incomplete pseudo-UNC cases in the test. Apologies for the earlier 'r5 clean' claim in the review log — this finding had landed and I misread the summary's Completed status as a verdict; correction posted.

Node.js path.isAbsolute Windows root-relative path \repo drive-qualified C:\ws documentation
💡 Result:
In Node.js, the path.isAbsolute method determines if a path is absolute by checking the literal string format [1][2]. On Windows, this method returns true for paths that are considered "absolute" by the Node.js path module's logic, which includes paths that start with a drive letter (e.g., C:\ws) or those starting with a UNC server/share path (e.g., \server) [1][3][4]. Regarding root-relative paths on Windows (e.g., \repo), Node.js currently treats these as absolute in the context of path.isAbsolute [5]. While standard Windows file system APIs classify paths that start with a directory separator but lack a drive letter as "relative to the root of the current drive" (not fully absolute) [5], the Node.js implementation of path.isAbsolute returns true for these strings [5]. This is a known ambiguity in the Node.js path module, as it does not implement a distinct "drive-relative" category to align with Windows' three-tier classification of paths (relative, drive-relative, and absolute) [5]. Therefore, if you provide the string "\repo" to path.isAbsolute on Windows, it will return true [5]. Similarly, a drive-qualified path like "C:\ws" is correctly identified as absolute and will return true [1][3]. For developers needing to handle drive-relative paths safely, relying solely on path.isAbsolute may be insufficient as it does not distinguish between fully qualified absolute paths and those anchored to the current drive's root [5].

qualifiedFolder(f, false) calls Node’s platform-specific isAbsolute, which accepts \repo and C:\ws on Windows. Use posix.isAbsolute(f) in the false branch and add Windows-host assertions.

Type of change
What does this PR do?
Extension-type integrations were presented as categorically unusable from the CLI ("not available from the CLI"). They aren't: with VS Code + the Altimate extension open on the project, the workspace engine discovers the bridge over the
~/.altimate/extension-rpc/sidecars, allowlists the extension tools into the session, and serves them. This PR makes the three presentation surfaces say what is actually true — no serving/allowlist/overlay behavior changes, only strings, listing rows, and metadata.datamate_manager list-integrations— with a live bridge for this project, extension-type rows are listed, marked "(via VS Code)" and counted; without one they stay omitted, with copy that says they serve while VS Code with the Altimate extension is open on this project instead of "not available from the CLI".missing.liveBridge()probe (engine-probes) — a read-only mirror of the engine's sidecar discovery: cwd prefix match, else the sole live bridge; dead pids skipped, never unlinked (stale-sidecar GC stays with the engine and the extension). This works because presentation only needs the same answer the engine will reach at spawn time, without connecting.Claims
list-integrationsoutput and metadata are bridge-conditional:bridge: truelists and counts extension rows;bridge: falseomits them with the "serve while VS Code … is open" copy.

The directory holds a handful of small files; not worth a TTL.test/altimate/tracing-finalize-sync.test.tsflakes locally on the dev rig (mtime resolution; pre-existing, untouched by this diff).How did you verify your code works?
