feat(workspace): publish a locally-authored skill to the linked workspace#1280sahrizvi wants to merge 3 commits into
Conversation
…pace (#1271) The upload half of `skill-sync.ts`, which only ever pulls. A skill written locally had no route to the workspace, and nothing in the CLI said so. Shaped so agents and commands can ride the same path later: a workspace skill is a named bundle of files, and nothing here is skill-specific except the endpoint it posts to. `collectBundle` and the binary guard take a directory, not a skill. Three rules the module exists to enforce, each a bug if skipped: **Refuse non-UTF-8 files, naming the path.** The wire format is `{path, content}` with content as a STRING — the server does `content.encode("utf-8")` inbound and returns a decoded string outbound. A bundle carrying a PNG cannot round-trip: the declared byte size stops matching after the re-encode and `skill-sync` skips the whole skill, logging a warning nobody sees. Caught at publish it is one clear local error; uncaught, the upload succeeds and the skill silently vanishes from every OTHER machine, days later, with nothing tying symptom to cause. Decoding is strict (`fatal: true`) because the default substitutes U+FFFD and would hand back a "valid" string that reassembles into a different file. **Never publish from the managed snapshot.** `.altimate-code/skill/_workspace` holds skills the workspace sent us and sits under the same `{skill,skills}/**` glob as the user's own — deliberately, since that is how they load. A publish that walked "every skill in this project" would send the workspace's own skills back to it. The check compares against a separator-terminated prefix, so `_workspace-notes` is not mistaken for something inside `_workspace`. **Remember the server's id, so a second publish updates.** Names are unique per creator server-side, so a blind re-create answers 409 rather than duplicating — but that turns an ordinary second publish into an error the user has to interpret. The id lives in a local ledger, not `SKILL.md` frontmatter. Frontmatter is committed, so the id would travel with the skill: a colleague cloning the repo and publishing would UPDATE the original author's bundle rather than create their own. It is keyed on the resolved directory and scoped to the account it was published under, and rows are shape-checked on read rather than cast, so a corrupt entry costs its own skill a re-create instead of a PATCH against a garbage id. `privacy` is left unset — the server defaults to `private`. Publishing should attach a skill to a workspace, not disclose it org-wide as a side effect of a command whose name says nothing about visibility. A 404 on update falls through to create: the skill was deleted in the workspace since we published it, and failing would strand the user with a local id they can neither see nor clear. Tests: 11 new, 443 across `test/altimate/workspace`. Mutation-checked — 8 mutations, 8 killed: non-fatal decoding, dropping the managed-snapshot guard, prefix-matching without the separator, always creating, swallowing the 409, not re-creating after a 404, not recording the id, and defaulting privacy to public each fail a test.

**A symlinked skill directory defeated the managed-snapshot check.** `path.resolve` is lexical: it normalises `..` and absolutises, but it does not follow links. So a skill directory that IS a link into `.altimate-code/skill/ _workspace` resolved to its own path, passed `isManagedSkill`, and the bundle walk then followed the link — publishing the workspace's own skills back to it under the user's name. Compared through `realpathSync` now, falling back to the lexical form for a path that does not exist, which cannot be a link into the snapshot anyway. **The bundle size guard could not stop the thing it exists to stop.** `collectBundle` read each file with `readFile` and only then checked the running total, so a single oversized file was pulled entirely into memory before being rejected. Size is checked before the read now; the cumulative check stays for many small files and as a backstop if the file grows in between. **A conflicting rename on the update path surfaced a raw API envelope.** The POST path maps 409 to `SkillNameConflictError`; the PATCH path only handled `NotFoundError`, so renaming a skill onto a name this creator already uses reached the caller as the server's own error shape — the exact outcome the typed errors in this module exist to prevent, and invisible from the create path. Tests: 14 in this file, 3 new, whole altimate suite green. Worth recording how the tests were arrived at, because the first versions were worthless: all three mutations SURVIVED. Asserting that an oversized bundle is rejected does not test this fix — the post-read check rejects it too — so the test now patches `readFile` and asserts the oversized file is never read at all. The other two had no coverage whatsoever. All three mutations fail now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012Q51zFUmPg1WwtS5CrGJE6

WARNING: Symlinked files and directories inside the skill are silently dropped from the published bundle
readdir(withFileTypes) reports a symlink as neither isFile() nor isDirectory(), so this continue skips symlinks with no error. But local skill discovery loads skills with Glob.scan(..., { symlink: true }) (src/skill/skill.ts lines 138, 225, 245, 261 — every scan in that file), which follows them. A skill that works locally through e.g. references -> ../shared/references therefore publishes a bundle silently missing those files, and on every other machine the pulled copy is incomplete — the exact "silently vanishes from every OTHER machine" failure that rule 1 in this module's header exists to prevent, arriving by a different route. Either follow the link (with a containment check against the skill root) or throw naming the symlink, as BinaryFileError does for non-UTF-8 files.

WARNING: The shared 15s request timeout aborts bundles well below the 10MB limit this module enforces
altimateRequest wraps every call in the shared REQUEST_TIMEOUT_MS = 15_000 AbortController budget (api-client.ts line 15/163), and that timer covers the upload itself. This module deliberately allows bundles up to 10MB — JSON-serialized, so larger still after string escaping — which needs ~5.5 Mbps of sustained throughput just to fit inside 15s. A legal bundle on a typical residential or cellular uplink therefore aborts every time with "Request to … timed out after 15s", with nothing telling the user the ceiling is time, not size. The existing req machinery was sized for small JSON payloads; this is its first multi-megabyte body. Consider a larger (or absent) timeout for these POST/PATCH calls — the local MAX_BUNDLE_BYTES guard already bounds the body.

SUGGESTION: An empty skill directory raises BundleTooLargeError
BundleTooLargeError is the size-ceiling type; an empty directory is the opposite condition. A caller switching on error types (or the future command surface this module awaits) will bucket "nothing to publish" as a size problem. A dedicated error type — or a plain Error — would keep the typed-error contract this module otherwise maintains. Note also that BundleTooLargeError never sets this.name, unlike its siblings, so err.name stays "Error".

SUGGESTION: The ledger key is lexical, so one directory reached by two paths becomes two skills
path.resolve does not follow symlinks — the exact property commit 77256d0 fixed isManagedSkill for. The same checkout reached once through a linked parent (/tmp/proj vs /private/tmp/proj on macOS, a symlinked worktree, differing case on an APFS volume) resolves to two ledger keys, so the second publish misses the recorded id, POSTs again, and surfaces SkillNameConflictError claiming the skill "was published from somewhere else" when it was in fact published from this machine. Keying on realpathSync with the same existence fallback isManagedSkill already uses would make ledger identity match path identity.

SUGGESTION: bytes is recomputed from contents collectBundle just measured
collectBundle already accumulates bytes while walking (and validates it against the limit). Returning {files, bytes} from it would avoid a second full pass over up to 10MB of decoded strings here, and would keep the reported number identical to the one the guard actually checked.

…lise its writes Two more from the cubic review on #1280. Both are the ledger describing something other than what is actually on the server. **One directory, two accounts, one id.** The ledger keyed on the resolved skill directory alone, so publishing the same skill under a second account overwrote the first account's record. Switching back found a row scoped to the other tenant, treated the skill as unpublished, created it again — and 409'd on the name that was already there, with the original id no longer reachable from this machine. The key now carries tenant and API URL alongside the directory, so each account keeps its own id. Reads still fall back to the old directory-only key, so ids written by an earlier version are not stranded into a needless re-create; the tenant check stays, because that fallback can return another account's row. **Concurrent publishes dropped each other's ids.** Each publish read the whole ledger, mutated its copy and wrote it back, so of two publishes in flight the later write carried the earlier one away, and that skill created again on its next run. Writes go through a promise chain now, and the re-read happens INSIDE the chain — reusing a copy read before the previous write landed would lose it just the same. Same shape `memory-index` already uses for the same reason. Tests: 16 in this file, 2 new, whole altimate suite green (5799 tests). Mutation-checked: keying by directory alone fails one, dropping the chain fails four.

Serialize ledger writes across processes.
ledgerWriteChain exists only in one process. If two OpenCode processes publish different skills at the same time, both can read the old ledger and write separate replacements. The last write then removes the other skill ID. The next publish for that skill creates again and can fail with a name conflict.
Use an inter-process lock or an atomic read-merge-write mechanism for altimate-published-skills.json. As per coding guidelines, protect shared file-write state from async races.

Isolate the credential stub per test. AltimateApi.getCredentials is mutated globally and restored only in afterAll; the account-switching test also changes it during execution. A parallel test can therefore observe the wrong credentials. Use a per-test dependency or another isolation mechanism, and retain afterEach cleanup for all shared state.

Make the concurrent-write regression deterministic.
Promise.all starts both publishes, but it does not ensure that both calls read the ledger before either call writes it. The old read-modify-write implementation can therefore pass this test depending on filesystem scheduling.
Add a controlled barrier around the initial ledger reads or writes. The test should fail reliably without the write queue.

WARNING: The ledger is written non-atomically, diverging from the writeJsonAtomic precedent this commit cites
recordPublished's comment says it serialises writes "the same way memory-index serialises its own", but memory-index.ts:104 pairs its serialisation with Filesystem.writeJsonAtomic (tmp-file + rename); this uses plain Filesystem.writeJson, whose writeFile can leave truncated JSON if the process is killed mid-write — and the ledgerWriteChain only fences writers within one process, so two concurrent altimate processes (CLI + TUI, or two CLI runs) still race the same file. When the file does end up half-written, readLedger's catch silently returns {}, dropping every skill's id at once: each subsequent publish re-POSTs and lands in the SkillNameConflictError dead-end that claims the skill "was published from somewhere else" when it was in fact published from this machine. Switching to the existing Filesystem.writeJsonAtomic (the ledger holds no secrets, so its lack of chmod is fine here) keeps the chain meaningful across crashes and cross-process writers.

SUGGESTION: The ledger read is not routed through ledgerWriteChain, so it can still race an in-flight write
recordPublished re-reads inside the chain (correctly), but knownPublicId reads outside it. A read that overlaps a queued/running write either observes a partially-written file (plain writeFile, no rename) or a ledger that does not yet contain the id — both surface here as null. Two concurrent publishes of the same skill then both take the POST path, and the loser is told via SkillNameConflictError that it "was published from somewhere else", which is false — it was this machine, and the next sequential publish works again, so the message actively misleads anyone debugging it. Performing the lookup as a task on ledgerWriteChain (returning the value from the task) closes both the stale-read and torn-read windows; the new concurrency test covers two different directories, where this residual race cannot show up.

Issue for this PR
Closes #1271
Type of change
What does this PR do?
Adds the upload half of
skill-sync.ts, which only ever pulls. A skill authoredlocally had no route to the workspace, and nothing in the CLI said so.
Note the original issue was wrong and has been corrected. It claimed this
needed a workspace API that does not exist. It does exist — create, update, write
bundle file, delete, and attach are all there. The missing half was entirely
client-side, which makes this much smaller than first scoped.
Shaped so agents and commands can ride the same path later: a workspace skill is a
named bundle of files, and nothing here is skill-specific except the endpoint it
posts to.
collectBundleand the binary guard take a directory, not a skill.Three rules, each a real bug if skipped:
Refuse non-UTF-8 files, naming the path. The wire format is
{path, content}with content as a string — the server doescontent.encode("utf-8")inbound and returns a decoded string outbound. Abundle carrying a PNG cannot round-trip: the declared byte size stops matching
after the re-encode and
skill-syncskips the whole skill, logging a warningnobody sees. Caught at publish it is one clear local error. Uncaught, the
upload succeeds and the skill silently vanishes from every other machine,
days later, with nothing tying the symptom to the cause. Decoding is strict
(
fatal: true); the default substitutes U+FFFD and would hand back a "valid"string that reassembles into a different file.
Never publish from the managed snapshot.
.altimate-code/skill/_workspaceholds skills the workspace sent us, under the same
{skill,skills}/**glob asthe user's own — deliberately, since that is how they load. A publish walking
"every skill in this project" would send the workspace's own skills back to it.
Remember the server's id, so a second publish updates. Names are unique per
creator, so a blind re-create answers 409 rather than duplicating — turning an
ordinary second publish into an error the user has to interpret.
Two decisions I made rather than block on — both worth a reviewer disagreeing
with:
SKILL.mdfrontmatter. Frontmatter iscommitted, so the id would travel with the skill: a colleague cloning the repo
and publishing would update the original author's bundle rather than create
their own. It would also put a server identifier in a hand-edited file and show
up in every diff.
privacyis left unset, so the server'sprivatedefault applies.Publishing should attach a skill to a workspace, not disclose it org-wide as a
side effect of a command whose name says nothing about visibility.
How did you verify your code works?
11 new tests, 443 across
test/altimate/workspace. Typecheck clean; the one lintfinding in the new source was a cast of on-disk JSON, replaced with a real shape
check so a corrupt row costs its own skill a re-create instead of a PATCH against
a garbage id.
Mutation-checked: 8 mutations, 8 killed — non-fatal decoding, dropping the
managed-snapshot guard, prefix-matching without the separator, always creating,
swallowing the 409, not re-creating after a 404, not recording the id, and
defaulting privacy to public each fail a test.
