feat(workspace): sync a bound workspace's custom skills into the project#1172sahrizvi wants to merge 17 commits into
Conversation
Adds `skill-sync.ts`, which pulls the custom skill bundles attached to the bound workspace into `.altimate-code/skill/_workspace/<publicId>/`, where the existing skill discovery finds them with no other change. Activation is not handled: a synced skill is listed in `<available_skills>` and loaded when the model invokes the Skill tool, exactly like a local one. Bundles are fetched per file rather than through `SkillDTO`, whose single `content` string cannot carry a skill's `references/` directory — and the Skill tool hands the model that directory to read from, so the whole bundle has to be on disk. Three guards carry the weight, each covered by a test that was checked by mutation: - A failed or unrecognised list is an error, never an empty workspace. The existing list helpers coerce an unknown envelope to `[]`, so a malformed 200 would otherwise delete a user's synced skills. - Rebinding purges the previous snapshot before pulling. `recordApprovedBinding` persists the new binding first and discovery never reads our manifest, so a rebind plus an ordinary network failure would otherwise feed the model another workspace's skills. - Downloads are checksummed and staged, then swapped. A partial bundle is never published, and any failure leaves the previous snapshot intact. Nothing outside `_workspace/` is written or removed — the directory boundary is the ownership marker, so author-written files are never modified to carry one. Also extends `api-client` with `altimateRequestBytes`, sharing the credential resolution, abort budget and error classification that `req` already has.
Read the merged backend rather than the route names, and three assumptions were
wrong:
- The router mounts at `/skills` (`app/main.py`), not `/datamates/custom-skills`.
- The list returns `Page[CustomSkillSummary]`, a paginated envelope, so a single
request can silently see one page of a tenant's shared library. Every page is
now walked, under a bound so a server that never advances `page` cannot spin.
- Nothing in the API exposes a checksum. `CustomSkillSummary` carries
`file_count`, explicitly "a count, not the inventory", and
`CustomSkillFileMeta` is `{path, size}`. Hash-based change detection was
therefore impossible.
Change detection is now the server's per-skill `updated_at`, which the summary
does carry, so an unchanged workspace still costs one list call and no detail or
file requests. Integrity falls back to byte length — weaker than a hash, but it
still catches the truncated download that would otherwise publish half a skill.
Getting the inventory needs the detail view, so a changed skill costs one extra
request.
Also fixes a vacuous test. The path-traversal case passed with the guard
removed: its stub fell through to the detail branch, so the size check aborted
the sync before the guard was ever reached, and it asserted on the wrong path —
an escape would land in `_workspace/`, not beside it. It now serves a
correctly-sized body so only the guard can stop the write, and fails when the
guard is removed.
All four guards re-checked by mutation: rebind purge, malformed-page handling,
size verification, path traversal.
Wires the skill mirror into the two moments a bound project can gain new skills. - `state.ts`: pull on bind, placed **above** the `alreadySeeded` early return. That marker is memory's one-shot seed gate; skills have a different lifecycle and must refresh on every bind, including a warm rebind. Awaited on the same `awaitBackfill` condition, because the CLI exits as soon as the handler returns. - `session/prompt.ts`: awaited sync before `createUserMessage`, which is what first materialises the skill registry via `Agent.get` -> `Skill.dirs()`. Syncing here makes skills pulled this turn visible in the same turn. - `skill/index.ts`: new `Skill.refresh()`. The registry is cached per instance across two separate `InstanceState`s (`discovered` and `state`); `state` closes over the discovery result, so both must be dropped. `Config.invalidate()` runs first, since the skill scan asks Config for the project config directories and that list is itself cached — on the first sync `.altimate-code/` may not have existed when Config last looked. Invalidation is gated on the snapshot actually changing, as `Config.invalidate()` rereads config for every instance. Tests cover both guards, and each was verified by mutation: - moving the bind sync below `alreadySeeded` fails the warm-bind test - dropping either half of `refresh` fails the mid-session skill test Also narrowed the existing "does not re-seed" counter to memory traffic; it counted every fetch, and skills now legitimately re-sync on each bind.
`SessionPrompt.prompt` runs on every message, so the sync added in the previous commit put an HTTP round-trip on every turn — in the one path whose first-answer latency is instrumented. The network pull is now done once per project per process. Refreshing the skill registry is driven off a `snapshotGeneration()` counter in `skill-sync` rather than the local call's own result, so a sync that happened elsewhere — a mid-session bind, which calls `syncSkills` directly — is still picked up on the next message without re-fetching just to discover whether anything moved. Covered by a test asserting the counter advances on a real change and stays put on a no-op sync; both mutations (always bump / never bump) fail it.
Verified against a local backend on `development` with a real skill
bundle in S3. Two assumptions baked into the sync were wrong, and each
would have made it publish nothing at all:
- The file endpoint answers `{path, content}` JSON, not raw bytes. The
sync fetched the body raw and compared its length to the advertised
`size`, so every file failed the integrity check and every snapshot was
abandoned. Now parsed as JSON, with the size compared against the
UTF-8 byte length of `content` — `size` is the stored object's byte
count, so a non-ASCII skill would fail a string-length comparison.
- The detail view wraps its body in `{skill: {...}}`; the list view does
not wrap. `parseDetailFiles` read `files` off the top level, found
nothing, and treated a healthy response as unrecognised.
`altimateRequestBytes` was added solely for the raw-bytes path and now
has no callers, so it goes rather than sitting as dead code.
The test stubs were built from the same wrong reading, which is why they
passed throughout; they now serve the shapes the real backend serves.
Added a case for a file body missing `content` — the previous suite left
that guard vacuous, and it is not redundant with the size check, since a
zero-byte file would let a coerced empty string through and publish
silently.
E2E confirmed against the live backend: bundle lands with `references/`
intact and byte-exact, the skill is discovered by the real registry, a
SaaS rename keeps the `public_id` directory, detach removes it, a dead
backend leaves the snapshot untouched, and a rebind purges the previous
workspace's skills.
TUI E2E showed the refresh never worked, for two independent reasons. Reverting rather than deepening it: making it work is a design change, not the few lines it looked like. - The imperative `Skill.refresh()` facade runs on `makeRuntime`'s own runtime, so it invalidates a different Skill service instance than the one the live session reads. Proved with a harness test: after calling the facade, a skill written mid-session still did not appear. - Even with that fixed, the gate could not fire. A bind syncs and consumes `changed: true`; the next `prompt` re-syncs, gets `changed: false`, and never invalidates. An earlier run in this branch appeared to confirm the refresh working. It did not — that process STARTED with the files already on disk, so discovery found them on its first read. The result was confounded. What is left is what is actually verified: the bundle syncs on bind and at session start, and a session that starts with a bound project sees the skill. A bind mid-session lands the files but needs a restart to show them; the limit is now documented at the call site rather than papered over by code that does not run. This restores `skill/index.ts` and `test/skill/skill.test.ts` to be byte-identical to origin/main — no `altimate_change` blocks to carry in either upstream file — and removes the snapshot-generation counter, which existed only to drive the invalidation.
… the cache Without this, workspace skills never reach a project that was linked on a different machine. The local binding cache is written only by an explicit link, and `syncSkills` read only that cache — so a fresh clone of a repo a teammate linked, a new machine, or cleared state all looked unbound. Running `link` did not help: the server reports the project as already linked, the picker answers "Already linked — nothing changed", and no local entry is ever written. The project was left permanently without its workspace's skills and with no way out from the CLI. `resolveBinding` falls back to `WorkspaceApi.getBindingForProject` and caches what it finds. Adopting a binding this way is a read, not an approval: the lookup is access-controlled server-side — a workspace the caller cannot see answers 404 exactly as an unbound remote does — so it can only surface a binding the caller could already see. It deliberately writes no `seededAt` and does not run the memory backfill. Pulling a workspace's skills is read-only; pushing this machine's memory into a shared workspace is a write, and that stays behind a real link. A failed lookup is "unknown", not "unbound": it returns null, leaves whatever is on disk alone, and is NOT memoized, so a network blip does not strand the project for the rest of the process. Only a definite 404 is memoized, so an unbound project pays one lookup per process rather than one per sync. Verified against the live backend: with the binding present server-side and the local cache wiped, `readLocalBinding` returns null while `resolveBinding` adopts datamate 8, the bundle syncs, and the TUI lists `e2e-probe` after the first turn. The written cache entry has no `seededAt`. Both guards are mutation-checked: reverting to `readLocalBinding` fails the fresh-clone test, and memoizing the error path fails the retry test.
A skill added to the workspace previously never reached a running session: the pull happened once per process, so it took a restart. This polls on an interval and refreshes the registry in place when something actually moved. Corrects the premise of the earlier revert. That change claimed the imperative `Skill.refresh()` facade invalidates a different service instance than the live session reads. It does not. `attach()` propagates the instance ALS into the facade's runtime, so a call from plain async code running under a session reaches that session's caches. The revert's harness provided the instance through Effect context only, never ALS, which is why it appeared to fail. Verified the other way round with a real `Instance.provide`: read, write a new skill, read again (still cached), refresh, read — the third read sees it. The wiring was the actual bug. A bind consumed `changed: true`, so the next turn's sync reported `changed: false` and the gate never fired. - `skill-sync`: `recentlySynced` gates the per-message poll on a 5-minute interval. Once per process means a skill added upstream never arrives; every turn means an HTTP round trip in the latency-measured path. The list is Postgres-only server-side, so a no-op check is cheap. - `prompt`: waits at most 2s for the sync, and does NOT cancel it past that. The workspace request budget is 15s — long enough that a slow backend would otherwise read as the agent hanging before it starts. Past the bound the sync completes and lands on a later turn. - `skill/index.ts`: `Skill.refresh()` restored, invalidating both `discovered` and `state`. Also stopped this file's test leaking `ALTIMATE_WORKSPACE` into other suites. It was set at module load, so other files' prompt path attempted a real sync against this sandbox's credentials and burned 15s timeouts — which is how the unbounded wait above got noticed. E2E: with a session already synced, a skill created and attached in the SaaS appears in the TUI's list after a later turn, no restart. Guards mutation checked — pinning `recentlySynced` true or false, and dropping either half of `refresh`, each fail a test.
`memory-sync` read only the local binding cache, which is written solely by an explicit link. Any directory holding a repo that IS bound therefore mirrored nothing, silently: a git worktree, a second clone of the same repo, a teammate's checkout, a new machine, cleared state. `currentBinding` returned null and the mirror wrote nothing — no error, no warning. Worktrees make this ordinary rather than rare. The cache is keyed by directory while the server matches on git remote first, so every worktree of a linked repo is a local miss and a server hit. Same one-line switch already made for skills, to the same `resolveBinding`: local cache first, else the server, cached for next time. It writes no `seededAt` and does not run the backfill, so adopting a binding still does not push this machine's memory into a shared workspace — that stays behind a real link. Pulling is safe; pushing is not. The import is aliased because `syncInternals.resolveBinding` is an unrelated test seam in this module. Covered both ways: a directory bound only on the server now mirrors, and a genuinely unbound one still does not. Reverting to `readLocalBinding` fails the first. Note the second case does not distinguish a null binding from one whose workspace has memory disabled — an invented-binding mutation survives it — but that is not a plausible regression and the test was left honest rather than fitted to it.
…ll sync
An independent audit of the feature surfaced twenty failure modes. These are
the eight that are security, data-loss or silent-no-op, all confirmed in the
code before fixing.
**Path traversal.** `public_id` went straight into `path.join(staging, id,
file.path)`. Only the per-file path was guarded, and the escape happens one
component earlier — a malformed or compromised listing could write anywhere
the process can. Now rejected unless it is a single usable path component.
**Data loss.** The managed directory was replaced or deleted wholesale with
no ownership check. Anything a user had at that path — a hand-written skill,
an older tool's output — was destroyed by a routine sync. The name is ours by
convention, and convention is not ownership: absent or carrying our manifest
now means ours, anything else is left alone and the sync declines.
**Partial snapshots were discoverable.** Staging was `_workspace.staging-<pid>`,
a sibling inside `.altimate-code/skill/`, which discovery globs as
`{skill,skills}/**/SKILL.md`. Half-downloaded bundles could be loaded as real
skills, and a SIGKILL left a permanently discoverable tree. Staging moved to
`.altimate-code/skill-staging/`, outside the scan, and stale trees are swept.
**A bind left the registry stale for the process lifetime.** The bind path
syncs and stamps the poll window, so the next turn skipped the only code that
refreshes — newly linked skills stayed invisible until restart. Snapshot
changes and registry refreshes are now tracked separately, so a turn notices
work another caller did without re-fetching.
**Failures consumed the poll window.** `lastSyncedAt` advanced even when the
sync threw, suppressing retry for a full interval on a blip. Only a run that
actually read the workspace list stamps now.
**Account switches kept the previous tenant's skills.** The poll window was
keyed on directory alone, so switching accounts inside the interval skipped
the very poll that would have noticed. It is now checked against the
credentials in play at that moment.
**A damaged snapshot was declared current forever.** `upToDate` compared only
ids and `updated_at`; a deleted or truncated file was never repaired. It now
verifies each file against the sizes the manifest already records.
**Committing another workspace's skills.** The tree is a server-derived
mirror with no business in a user's history, and it showed up in `git status`
for every bound project. It now carries a `.gitignore` of `*`, staged so it
lands atomically with the snapshot.
Also: the file endpoint's echoed `path` is now checked against the one
requested — no checksum exists, so a mis-routed same-length response would
otherwise be stored under the wrong name. And the negative binding cache is
tenant-scoped with a TTL, instead of a permanent process-wide memo that made
a newly linked project invisible until restart.
Every guard is mutation-checked. Two notes on that: the staging test had to
observe mid-sync, since staging is removed on success and checking afterwards
proved nothing; and the failure-stamping guard is not independently
observable, because the account check already forces a re-poll — it is kept as
defence, not because a test pins it.
E2E against a live backend: bundle syncs with the ignore file, no strays in
the scanned directory, `git status` clean, a deleted file is repaired rather
than declared current, and a hand-written directory survives with the sync
declining.
Second pass over the audit findings.
**The swap had a window with no snapshot.** Publishing did `rm(root)` then
`rename(staging, root)`; a crash or a reader in between saw the skills vanish,
and the catch still logged "kept the existing snapshot". The live tree is now
renamed aside, the new one moved into place, and the retired tree deleted only
after that succeeds — with the old one restored if the swap fails.
**An inconsistent page could delete a good snapshot.** `{items: [], total: 4}`
was read as an empty workspace, and "empty" is the one answer that removes the
tree. A page whose envelope claims rows while returning none is now an error.
**No ceiling on a sync.** Every file is read fully into memory before it
reaches disk, and nothing upstream bounds a workspace, so one oversized bundle
was an OOM rather than a failed sync. Capped at 2000 files / 32 MB, counted on
the advertised inventory before anything downloads.
**The header comment was wrong about activation**, in a way that matters:
`alwaysApply` and `applyPaths` DO survive into `Info` and are injected by
`collectAutoLoadedSkills` into every applicable system prompt, with no
Skill-tool call and no permission prompt. So anyone who can upload a skill to a
workspace can put standing instructions into every bound member's prompts. The
comment now says so. Deliberately NOT changed in code: whether workspace skills
may auto-activate is a product decision, and stripping frontmatter an author
wrote is not a call this module should make silently. Also corrected the
documented file-endpoint shape, still stale from the original reading.
Tests: an inconsistent empty page, a bundle past the ceiling, and — the gap the
audit was most pointed about — a synced bundle that is actually a loadable
skill. The existing fixtures assert only that bytes reached disk, which does
not show the feature works; this one parses the frontmatter, checks the
bundled reference survived, and checks the path is where discovery globs.
Two guards are honestly not pinned. The ceiling test counts files rather than
bytes, because an oversized `size` trips the integrity check first and would
pass without any ceiling existing. And the atomic swap has no test: proving it
needs a fault injected between two renames, which this harness cannot do — it
is kept because it is strictly better, not because a test holds it.
E2E: both workspace skills sync with valid frontmatter, the ignore file lands,
no strays in the scanned directory, no staging left behind but its own ignore
file, and `git status` is clean.
Disconnecting an account left the workspace's skills on disk and loading. `getCredentials()` threw, the sync returned early, and the snapshot stayed — discovery reads whatever is on disk without consulting the manifest, so a disconnected user kept getting the workspace's skills. Turning `ALTIMATE_WORKSPACE` off behaved the same way: the opt-out did not take effect until the files were deleted by hand. That compounds with a property documented in the previous commit: a skill carrying `alwaysApply` is injected into every applicable system prompt with no tool call, so what kept loading is also what can act on its own. Both paths now remove the snapshot, and only a tree this client owns. Disconnected is deliberately distinguished from "could not read the credentials". The first is a decision the user made and must take effect; the second is unknown, and unknown never destroys a snapshot — the same rule the list response and the binding lookup already follow. A corrupt credentials file therefore keeps the skills. The check runs before `resolveBinding`, which needs credentials itself: placed after, a disconnected client returned on a null binding and never reached it. That is not hypothetical — the first version of this fix did exactly that and the test caught it. Verified live: sync -> 2 skills; disconnect -> removed; reconnect -> 2 skills again; corrupt credentials -> kept. Each guard mutation-checked, including the destructive mutation that treats an unreadable file as a disconnect.

Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to This change downloads workspace skills into projects and exposes them to model sessions. Concurrent synchronizations can publish stale data or remove a newer snapshot, malformed binding responses can be cached without project identity, and ownership and test-isolation concerns still require follow-up; workspace publishers also gain a model-visible instruction path.

Seven reviewers, verdict REQUEST CHANGES. This covers the four blocking findings plus everything cheap enough to land with them. **C1 — sweep followed symlinks and deleted outside the tree.** `readdir` follows links, so a repo shipping `.altimate-code/skill-staging -> ../..` (git tracks symlinks, so it survives a clone) had the sweep enumerate and recursively delete the target. Symlinked ANCESTORS were equally exposed: every mkdir, rename and write resolves through them. Nothing here should traverse a link, so `pathsAreReal` refuses rather than trying to make traversal safe, and the sweep lstats each entry and unlinks a link instead of recursing into it. **M1 — every readdir failure meant "ours", and then deleted.** ENOTDIR (a plain file at the path) and EACCES both returned true, handing a user's file to `fs.rm` — the exact outcome the guard exists to prevent. Only ENOENT means absent now. Ownership also rested on the FILENAME `.manifest.json`; a directory holding an unrelated or corrupt one was deleted wholesale. It must now parse as ours. **M2 (partial) — the sweep destroyed other processes' in-flight staging.** A sibling's live `pending-<pid>` was deleted mid-write, so it published a snapshot missing everything written before the sweep with a manifest claiming those files. Entries owned by a live PID are now left alone. The full inter-process lock is deferred; this removes the path that publishes a corrupt tree. **M4 — an account switch left the previous tenant's skills live.** `resolveBinding` collapses "confirmed unbound" and "lookup failed" into null, and the early return on that happened BEFORE the foreign-manifest purge — so switching to an account with no binding kept tenant A's skills on disk and in tenant B's prompts, with every retry hitting the same return. Credentials and the manifest are now read first, and a snapshot belonging to another account is dropped without waiting for a binding that will never arrive. Also landed: - **M5 (escaping half)** — `skill.content` went raw between `<auto_loaded_skill>` tags while only the name was escaped, so a body containing the closing tag broke out and continued as unwrapped system-prompt text, able to impersonate the harness's own framing. Skill bodies are remote content now, which is what makes this reachable. - **M6 (OOM half)** — the response body was buffered whole, so a file declared as 10 bytes returning 500 MB crashed before any size check. Bounded by Content-Length and by a cut-off on the stream itself. - **M7** — a missing or nonsense `pages` silently became 1, turning a partial first page into "the whole workspace" and pruning the rest. It must now be a finite integer >= 1, and the echoed `page` must match the one requested. - **m1** — the echoed-path identity check was skipped when the field was absent, which is precisely the mis-routed case it was written for. - **m2/n1** — `.manifest.json` and `.gitignore` are reserved as ids (either would break that workspace's sync permanently with EISDIR); NUL check made symmetrical across both path guards. - **m4** — a `public_id` repeated across pages made `upToDate` permanently false and re-downloaded the workspace every poll. - **m5** — joining an in-flight sync returned a hard-coded `changed:false` rather than the run's real outcome. - **m6** — `isEnabled()` is checked before the credentials read: it removes a per-message file read when the feature is off, and closes the opposite hole where turning the flag off after a sync left the snapshot live for a full poll interval. Tests for each, all mutation-checked. Two notes on that: a plain file at the managed path is caught by C1's symlink check before M1's error handling, so M1 is pinned by the corrupt- and foreign-manifest cases instead; and the review was right that "a synced bundle is a real skill discovery can load" never invoked discovery — it now claims only shape, and the end-to-end claim is made in test/skill/skill.test.ts where the instance harness exists. Added the multi-page pagination coverage all seven reviewers asked for. Re-verified against the live backend after the changes: three skills sync, no staging left behind, and a model invokes a synced skill and reads its bundled reference.

…estly The review found the code and the PR description disagreeing about whether memory upload requires an explicit link. The code is what was intended; the prose overclaimed. Precisely: adopting a server-side binding DOES enable the ongoing memory mirror, which POSTs blocks to the workspace. Only the one-shot backfill of memory this machine already held stays behind an explicit link, via `seededAt`. The PR said "pushing this machine's memory into a shared workspace stays behind a real link", which is true of the backfill and not of the mirror. The description is corrected rather than the behaviour: a worktree of a linked repo is the same project by the same user, and a mirror that silently does nothing there is the bug being fixed. `CachedBinding.adopted` now records how a row was obtained. `resolveBinding` writes into the same cache file `recordApprovedBinding` does, so without a marker no consumer can tell adoption from approval — and the absent `seededAt` is not a substitute, since only the memory backfill consults it. Any future gate meaning "the user linked this" can now require `!adopted` instead of inheriting adopted rows for free. The memory test that encodes this decision now says so in as many words, with the reasoning and an instruction to flip it if the trade is ever reversed.

…when off CI caught two things. **Marker Guard**: `refresh` was added to the upstream `Service.of(...)` line outside the marker block that introduced it. Wrapped. **The per-turn hook did work even with the feature off.** `recentlySynced` returns false when disabled, so every turn still called `syncSkills`, which stat'd the managed path before returning. Now the whole block is skipped. That path runs for every user, including the ones who never opted in. Written as a conditional rather than an early `return`: inside `prompt`'s try block a `return` exits `prompt` itself and skips `createUserMessage` — the message the function exists to produce. My first version of this had that bug.

Isolate mutable test fixtures from parallel tests.
When Bun runs tests concurrently, these shared mutations can overlap. One test can then use another test’s fetch stub, environment value, binding seam, or captured requests. Use a per-test fixture with guaranteed teardown, or explicitly serialize these tests.

WARNING: Opt-out (feature flag off) no longer removes an existing synced snapshot.
The disabled branch in syncSkills (skill-sync.ts line 434) is the only path that removes a snapshot on opt-out, but this if (skillSync.isEnabled()) guard makes it unreachable from the per-turn hook: when the flag is off the whole block is skipped, so syncSkills (and its deactivate call) never runs. The recentlySynced guard added specifically to close this hole (if (!isEnabled()) return false in skill-sync.ts:161) is now dead code for this path, since recentlySynced is only reached inside this block.
Result: after a user disables ALTIMATE_WORKSPACE, skills already synced to .altimate-code/skill/_workspace/ stay on disk and keep being discovered and injected (including any alwaysApply skill), because discovery does not consult the flag. This contradicts the module's stated safety property ("Disconnect or feature opt-out removes the snapshot") and the recentlySynced comment that claims to fix it. The opt-out deactivation should run even when the flag is off — e.g. call syncSkills(dir) unconditionally, or invoke the disabled-path deactivate directly without the surrounding stat/network work.

SUGGESTION: Redundant altimate_change markers nested inside an already-marked block.
The refresh facade is added inside the block opened at line 452 (altimate_change start — restore the imperative Promise wrapper …), so its own start/end markers are redundant. Nested markers inside an already-marked block are the pattern previously false-positived in #904 and make marker-coverage accounting harder to reason about. Either drop the inner // altimate_change start / // altimate_change end around refresh (it is already inside a marked block), or move refresh outside the outer block with its own markers.

Run disabled-state cleanup and registry invalidation.
When skillSync.isEnabled() is false, prompt skips both syncSkills() and Skill.refresh(). An existing _workspace snapshot or already-loaded registry can therefore continue exposing old workspace skills. Ensure the disabled path removes managed snapshots and invalidates the registry, while preserving the no-work path for sessions that never created a snapshot.

Re-trigger cubic
Four bot reviewers on the PR. The most important one caught a regression I introduced two commits ago. **Opt-out stopped removing the snapshot (Kilo).** The `isEnabled()` guard I added to keep the per-turn hook off the latency path made `syncSkills`'s disabled branch unreachable — and that branch is the ONLY thing that removes an already-synced snapshot. Discovery does not consult the flag, so after disabling the feature the skills stayed on disk and kept loading, `alwaysApply` included. I had built that deactivation deliberately, then broke it while fixing something else. The hook now runs the disabled branch (a single stat) and refreshes the registry when it drops a snapshot. **A symlinked `.altimate-code` bypassed the symlink guard on opt-out (cubic P1).** The disabled branch deactivates before the check inside `run`, so the purge could follow a link out of the project. Gated on the same check. **A confirmed unbind left the workspace's skills active (cubic P1).** `resolveBinding` collapsed "the server says unbound" and "we could not find out" into null, and the sync returned on both. Binding resolution is now tri-state: a confirmed unbind takes the snapshot out of service, and unknown still changes nothing — deleting on a network blip would wipe a snapshot the user is entitled to. **A malformed 2xx binding body crashed the sync (cubic P2).** The dereference sat outside the lookup's try. It is validated now and treated as unknown. **The response cap applied to every request (cubic P2).** The 8 MB bound I added for skill downloads also hit memory `/list`, which embeds block content and is deliberately not capped server-side — a regression risk for requests that work today. It is opt-in now, set only on skill file downloads, and the bodyless branch that bypassed it enforces it too. **The wait timer was never cleared (CodeRabbit).** An armed timer keeps the event loop alive, so a short-lived `run` lingered for the rest of the bound, once per turn. **Test isolation (cubic P2, CodeRabbit).** `XDG_STATE_HOME` and `OPENCODE_TEST_HOME` were set at module load, so another file in the same bun worker had its config, state and credential reads redirected into this sandbox. Scoped per test, like the workspace flag already was. The memory suite's `serverBinding` fixture is reset per test for the same reason. Deferred with reasons: revalidating cached POSITIVE bindings on a TTL (cubic P1) — it needs a rebind elsewhere during a live process, and the fix trades against offline behaviour; and a no-op fixture assignment (cubic P3). Every fix has a test, all mutation-checked. The symlink-purge test needed a tree at the link target to be sensitive at all — without one it passed whether or not the guard existed. Re-verified against the live backend: three skills sync, no staging residue, `git status` clean, and a model invokes a synced skill and reads its bundled reference.

Revalidate cached bindings before retaining the snapshot.
A local binding currently bypasses the server lookup. If the server binding changes, syncSkills still treats the project as bound and keeps the stale snapshot discoverable. Make the server result authoritative during synchronization, and use the cache only when the lookup is unknown. Add a test for a cached binding with a server response of 404.

including clearing the binding on a 404, and use the cached binding only when
the server lookup is unknown. Add a test covering a cached binding with a server
404 and verifying the stale binding is not retained.

Two reviewers flagged this independently — cubic P1 (confidence 9) and CodeRabbit Major, filed as sensitive-data exposure. I had deferred it as pilot-rare. That was wrong, and the reason is that the local cache is written by an explicit link and otherwise never expires: once a project is rebound or detached in the SaaS, this machine keeps serving the OLD workspace's skills forever, not just until some window closes. `alwaysApply` bodies included. The server is authoritative now. A cached binding is trusted inside a 5-minute window; past it the server is asked: - confirmed unbound -> the cached row is dropped and the snapshot taken out of service, so a later read cannot resurrect it from disk - rebound elsewhere -> the server's answer replaces the cached one - unreachable -> the cache stands. Revalidation must not tear down a working setup over a network blip, which is the same error-is-not-empty rule the rest of this feature follows Adoption stamps the validation clock, so a freshly adopted binding is not immediately re-checked. Tests for all three outcomes, including the cached-binding-with-404 case CodeRabbit asked for. Mutation-checked: trusting the cache forever, treating unreachable as unbound, and leaving the stale row behind each fail. Two test-fixture corrections that were mine, not the code's: a revalidation lookup is not a detail fetch (the unchanged-workspace counter) and not memory traffic (the re-seed counter), and my first offline test served an empty list, so the snapshot was deleted for an entirely correct but unrelated reason. Also REVERTED part of the previous commit. cubic asked for XDG_STATE_HOME and OPENCODE_TEST_HOME to be scoped per test like the workspace flag. Doing that broke seven tests in onboarding/materialize.test.ts, which began materializing into the real home directory: files sharing a bun worker set these at module load, and restoring "the original" after each test deletes theirs mid-run. Flipping them per test is worse than leaving them set. The reasoning is now a comment there so the next reader does not retry it.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Isolate the shared test fixture for parallel execution.
beforeEach writes shared project and ALTIMATE_WORKSPACE state. The suite also uses process-global fetch stubs. If tests overlap in one Bun worker, one test can replace another test’s project, fetch handler, or environment value. Its afterEach can then restore that state before the other test completes.
Use a serialized fixture that covers all shared globals, or remove the global seams from individual tests.
As per coding guidelines, “Tests using global mock.module, dispatchers, or similar shared state must provide teardown and isolation safe for parallel bun test execution.”

WARNING: forgetBinding deletes a freshly-linked binding when lookupBinding answers unbound from the stale serverLookupMissed memo, not a fresh server check.
lookupBinding short-circuits to { status: "unbound" } when serverLookupMissed holds a hit inside MISS_TTL_MS (5 min) — without contacting the server. This new revalidation path treats that memoized unbound as authoritative and deletes the local row. Concretely: a project opened while unlinked sets serverLookupMissed on its first turn; if the user then links within 5 minutes, recordApprovedBinding writes the row and fires syncSkills, which reaches this branch, hits the stale miss, and deletes the just-written row. The project then stays unbound (no workspace skills) until the memo expires. A freshly-linked project must not have its binding undone by a stale negative cache. Clear serverLookupMissed for the directory in recordApprovedBinding, or require a fresh server confirmation before calling forgetBinding.

SUGGESTION: Revalidating a matching binding clobbers the cached row with an adopted entry, losing seededAt and forcing a redundant memory backfill later.
lookupBinding has already written a fresh adopted: true row (no seededAt, new linkedAt) to the cache before control returns here. Returning local on this line is correct, but the on-disk row was overwritten: seededAt is dropped (so a later explicit re-link re-runs the memory backfill) and an explicit-link row is relabelled adopted. When the server confirms the same workspace, skip the cache write in lookupBinding (or preserve the existing row's seededAt/adopted flags).

P3: `lastValidatedAt` is keyed only by canonical directory, while the sibling `serverLookupMissed` map is keyed by `tenant\u0000apiUrl\u0000directory` precisely so an account switch does not inherit the other account's verdict (see its comment at state.ts:260-264). Because `lastValidatedAt` is in-memory and the TUI is long-lived, a timestamp written under account A suppresses revalidation for account B's cached binding of the same directory for up to `REVALIDATE_MS` after a switch: `readLocalBinding` returns B's row (the cache file is tenant-scoped), then the fresh A timestamp short-circuits the server check.

P2: lookupBinding rewrites the cache with an adopted row before this same-workspace branch returns local, dropping seededAt and changing explicit-link metadata. Preserve the existing cache row's seededAt and adopted fields when the server confirms the same workspace.

There was a problem hiding this comment.
P3: lastValidatedAt is keyed only by canonical directory, while the sibling serverLookupMissed map is keyed by tenant\u0000apiUrl\u0000directory precisely so an account switch does not inherit the other account's verdict (see its comment at state.ts:260-264). Because lastValidatedAt is in-memory and the TUI is long-lived, a timestamp written under account A suppresses revalidation for account B's cached binding of the same directory for up to REVALIDATE_MS after a switch: readLocalBinding returns B's row (the cache file is tenant-scoped), then the fresh A timestamp short-circuits the server check. If B detached or rebound the project in the SaaS, the old workspace's skills keep serving for up to 5 minutes. Key the map by tenant+apiUrl+directory, matching serverLookupMissed.

Closes #1173
Type of change
What does this PR do?
A project bound to an Altimate workspace pulls that workspace's uploaded skill
bundles into
.altimate-code/skill/_workspace/<public_id>/, where the existingskill discovery finds them. Whole bundle, including
references/, because theSkill tool hands the model the skill's directory and it reads those files
itself. Keyed on
public_id, not name, so a rename in the SaaS doesn't orphan adirectory.
Syncs on bind and on the first turn, then re-polls every 5 minutes so a skill
added in the SaaS reaches a session that is already open. Activation is
model-dependent for v0: skills appear in
<available_skills>and load when themodel invokes the Skill tool.
Two design rules do most of the work:
is on disk. "Empty workspace" is the one answer that deletes the tree, so it
has to be unambiguous. Same rule for the binding lookup and file reads.
or carries a manifest we can parse. Anything else is a user's file and the
sync declines rather than deleting it.
Binding resolution falls back to the server, because the local cache is written
only by an explicit link — so a git worktree, a second clone or a teammate's
checkout looked unbound and got nothing. The lookup is access-controlled
server-side, so it can only surface a binding the caller could already see.
Adoption also enables the ongoing memory mirror; only the one-shot backfill
stays behind an explicit link. Adopted rows are marked so that stays
distinguishable.

Unit: 38 tests on the sync, plus discovery and memory coverage. Full suite
green. Every guard is mutation-checked — the code is broken deliberately and the
test must fail. Two guards are honestly not pinned and are marked as such in the
commits.

A 7-reviewer consensus review returned REQUEST CHANGES; all blocking findings
are fixed (symlink traversal in the sweep, ownership on any
readdirerror,cross-process staging deletion, account-switch leakage), plus prompt-injection
escaping of skill bodies, a response-size bound, and pagination validation.
Deferred items are listed in the commits.
