fix: add an MCP status command and report discovered-config drift - #1160
Merged
Merged
Conversation
Two defects where the diagnostic information already exists in the
process and is discarded before it reaches the user.
`server unavailable` logged `status.status` — the constant string
`"failed"` on that branch — and dropped `status.error`, the field
holding the actual message (`401 Unauthorized`, a transport error,
`Invalid MCP URL for "<key>"`). Extracted `unavailableLogFields()` as a
pure function so the payload is testable without standing up a
transport, and so a later edit cannot quietly drop the field again.
Environment variables that resolve to empty were never named. A
`{env:VAR}` with nothing set becomes `""`, the config parses clean, and
the server launches with a blank credential — usually a password —
failing later with an error naming neither the variable nor the file.
The names are now recorded at both substitution sites: per-server for
discovered external configs, per-file for the main config. They surface
in `/mcps` and `mcp list`, shown even when the server reports connected,
because a blank credential often connects and fails on first real use.
An unresolved bare `${VAR}` is deliberately left literal by the config
layer so a later runtime layer can fill it (the bedrock provider fills
`${AWS_REGION}` from the effective region). That case is not reported.
Closes #1121

`status` is the name people reach for when a server will not connect, and it was the one name that did not exist. The gap was narrower than it looks: `mcp list` already probed live and already printed the failure reason, so `status` is registered as a sibling sharing that handler rather than a second view to keep in sync. It is a distinct command rather than an alias because an alias widens yargs' alias column enough to rewrap unrelated sibling rows in the help output. MCP discovery is first-source-wins, so a server already present in the user's config was skipped outright and a changed `.vscode/mcp.json` — a new port, a moved command — was never mentioned. `driftFields()` now reports which fields disagree, naming nested keys individually (`environment.ALTIMATE_EXTENSION_RPC`) so the message points at the thing to fix. The configured value still wins; silently overwriting a user's own config would be worse than the silence it replaces.

WARNING: DRIFT_IGNORED omits updatedAt, so datamate-synced servers always report a spurious updatedAt drift
normalizeMcpConfig preserves updatedAt on configured entries (config.ts:107, config.ts:127) and datamate-transport.ts writes it when syncing the datamate entry from .vscode/mcp.json into altimate-code.json. Discovery's transform in this file never copies updatedAt, so every comparison sees it present on the configured side and undefined on the discovered side — JSON.stringify(undefined) !== JSON.stringify("...") reports it as drift. A datamate-synced server therefore prints "differs from ...: updatedAt (config wins)" on every mcp list/mcp status.

SUGGESTION: sources.join(", ") attributes drift to every contributing source, not the source that defined the server
sources is the full contributingSources list from discoverExternalMcp, so when a project has servers from several files (.vscode/mcp.json, ~/.claude.json, ...), the "differs from X" message names all of them for every server. This weakens the "where to look" signal that #878 is meant to provide. Consider tracking the per-server source (e.g. in addServersFromFile) and passing that instead.

Addresses the review findings on this PR.
`_unresolvedEnv` only ever grew. The recording site sits inside an
`unresolvedNames.length > 0` guard, so a discovery run where every
variable resolved never touched the map — a server whose `{env:VAR}`
had since been set kept its old entry and `/mcps` went on telling the
user to set a variable that already worked. It is now cleared at the
start of each `discoverExternalMcp` and unioned within that run, which
is what the docstring already claimed. Clearing per run also stops one
project's discovery from mixing into another's under a shared server
name, and stops the map growing for the life of the process.
`_blankedEnv` had the mirror-image defect. A remote config substitutes
its `url` and then each header separately, all under one source, and
each call *replaced* that source's record — so a blank credential found
in the url was erased by a later clean header call and `mcp list` never
mentioned it. Substitution now unions, with an explicit
`resetBlankedEnvVars` at the two load sites.
Two tests were not testing what they claimed:
- The `/mcps` "says nothing extra" case compared `formatMcpStatusForDisplay(..., [])`
against the same call with the argument omitted, which defaults to `[]`.
Both sides were byte-identical, so it passed even if the function
appended an "unresolved" suffix. It now asserts against a literal.
- The `mcp list` E2E test asserted only that the server name appeared
and that argument parsing had not broken. It never asserted the
failure reason reached the user, which is this PR's entire point — it
passed with `status.error` dropped. It now requires the surfaced
error text.
New tests cover the staleness fix in both directions: a variable that
gets set stops being reported, and one that stays unset keeps being
reported across runs. Mutation-tested — removing the reset fails the
first.
Full opencode suite: 11489 pass, 0 fail.

Merges the env-diagnostics branch and addresses this PR's review findings.
`updatedAt` now joins DRIFT_IGNORED. `normalizeMcpConfig` preserves it on
the configured entry and discovery never produces one, so every
comparison saw a string against `undefined` and reported drift on every
`mcp list` for any datamate-synced server — the feature cried wolf on
the exact servers it was built for.
Comparison is order-independent. `JSON.stringify` made `{a,b}` and
`{b,a}` look like drift, so equivalent `oauth`/`headersCommand` objects
were reported as differing.
Nested blocks are compared when EITHER side has one, not only when both
do. A server that gained or lost an `environment` wholesale used to
report the bare word "environment" and lose the key that actually
differs, which is the detail this function exists to provide. An empty
block against a missing one has no key to name, so that case still
reports the top-level field.
Drift is attributed to the file that actually defined the server rather
than to `sources.join(", ")`, which named every contributing file for
every drifted server and destroyed the "where to look" signal.
Drift and blank-variable warnings are cleared at the start of each
discovery run — a removed server or a resolved difference left a stale
entry that `mcp status` kept reporting — and they now survive the
nothing-to-list early return, where an enabled-only override for a
discovered server previously silenced them entirely.
Marker scoping fixed: the "per-field env-var resolution" block ran
unclosed to three stacked `altimate_change end` lines, swallowing the
#701 and #878 blocks. Marker Guard checks balance, not scoping, so this
passed CI while over-claiming unrelated code. They are siblings now.
Full opencode suite: 11503 pass. The two failures in that run
(`pty` ordering, `opencode run` subprocess) are pre-existing flakes —
both pass on isolated re-runs and neither file is touched here.

Follow-up to the previous commit on this PR, from the second review round.
Switching `_blankedEnv` from replace to union meant callers must clear
first, and two paths were not migrated:
* The well-known remote flow records the blanks it finds while
substituting `remote_config.url` and each header under the wellknown
URL, then hands the fetched body to `loadConfig` under that *same*
source — whose reset promptly deleted them. Those names were never
re-recorded, because the text `loadConfig` receives is already
substituted. `loadConfig` now takes `keepDiagnostics` and that nested
call sets it.
* `config/tui.ts` calls `substitute` directly with no paired reset.
Previously a clean parse self-healed via the `else delete` branch;
without it a `{env:VAR}` in tui.json that was later fixed would have
been reported blank for the life of the process. It resets now.
The staleness tests also mutated process-wide `process.env` without
saving what was there. They now capture and restore it in
`beforeEach`/`afterEach`, so a parallel `bun test` cannot observe a
variable this file removed or left behind.
Full opencode suite: 11489 pass, 0 fail.

…fix/mcp-status-drift
…Config Replaces the `keepDiagnostics` flag from the previous commit. That flag required widening `loadConfig`'s signature, and a modified signature line in an upstream-shared file cannot be wrapped in `altimate_change` markers in a form Marker Guard accepts — it flagged the line whatever the surrounding markers looked like. The signature is restored untouched. The reset now sits with the callers that actually begin a load: every file-based load via `loadFile`, `OPENCODE_CONFIG_CONTENT`, the console-managed config, and macOS managed preferences. The well-known remote flow is deliberately left out — it records the blanks found in `remote_config.url` and its headers under that same source before handing the fetched body to `loadConfig`, so a reset in there discarded them. Keeping the reset out of `loadConfig` makes that ordering explicit instead of encoding it in a flag. Behaviour is unchanged from the previous commit; this is about where the clearing lives and keeping the shared signature pristine. config/mcp suites: 458 pass, 0 fail.

SUGGESTION: _drift and _discoveredSource are process-wide singletons cleared at the top of the async discoverExternalMcp and repopulated across its await boundary — racy under concurrent discovery
resetConfigDrift() and _discoveredSource.clear() run before the first await, but _discoveredSource.set() (in addServersFromFile) runs only after several await readJsonSafe(...) calls, and _drift is repopulated by setConfigDrift in config.ts after this function returns. The comment above already contemplates "a daemon that discovers for a second project"; if two projects' config loads run discovery concurrently (two sessions in opencode serve), the clears/writes interleave, so one project's discoveredSource(name) can return the other project's file and resetConfigDrift() can wipe the other run's just-written drift. The configured value still wins, so this is only wrong diagnostic attribution — consider keying these maps by projectDir or serializing discovery if concurrent loads are possible.

Same missing spawnSync error guard flagged in PR 1159 mcp-env-diagnostics.test.ts — this is a copy-paste without that fix. spawnSync returns { status: null, error } on timeout or ENOENT rather than throwing. The output() helper swallows that silently, so spawn failure produces empty output and the first assertion fails as 'expected empty string to contain datamate' with no indication that the subprocess never ran. Same fix applies: check r.error and r.status === null before reading stdout/stderr, and throw a clear message.

There was a problem hiding this comment.
configDrift() is exported and read by reportConfigDiagnostics() in mcp list / mcp status, but prompt.ts's /mcps handler never calls it. A user debugging a silently-failing server via /mcps mid-session sees neither drift warnings here nor blankedEnvVars warnings (the latter flagged in PR #1159). Both diagnostic surfaces are supposed to solve the same 'why won't this server connect' problem, but the session command /mcps consistently receives only unresolvedEnvVars while the CLI surfaces the full picture. The pattern repeats with each new diagnostic type added, so the gap between CLI and session view will keep widening without an explicit design decision to sync them.
…eted
The reset in `loadFile` sat after `if (!text) return {}`, so a config
file that was deleted or emptied never cleared what it had recorded
while it still contained a `{env:VAR}`. `mcp list` and `/mcps` went on
warning about a variable that appears in no config at all. It runs at
the top of `loadFile` now, before the file is even read.
Three reviewers flagged this independently, and it is the third
placement mistake in this record — the reset landing after an early
return, inside the wrong function, or on a shared signature that cannot
be marked. The underlying reason is that `blankedEnvVars` had no test
coverage whatsoever, so nothing failed when the placement was wrong.
`test/config/blanked-env.test.ts` now pins the contract every call site
has to honour: substitution unions into a source, a later clean pass does
not erase an earlier finding, and only a reset clears. Mutation-tested —
restoring the old replace-semantics fails two of the five.
Full opencode suite: 11652 pass. The single failure in that run
(`pty` ordering) is the pre-existing flake; it passes on an isolated
re-run and no pty file is touched here.

…fix/mcp-status-drift
…rness
`/mcps` reported only the per-server unresolved variables from discovery,
while `mcp list` also reported file-scoped blanks. A server templated as
`"url": "https://{env:MY_HOST}/mcp"` records against the config file
rather than the server, so with `MY_HOST` unset the CLI named it and the
session view said nothing — and the session view is where someone is
when a server will not connect. The wording is extracted into
`formatBlankedEnvForDisplay` so it is testable without standing up a
session; `/mcps` is otherwise only reachable through the whole handler.
The subprocess harness moves to `test/cli/fixtures/isolated-cli.ts`. It
was duplicated verbatim across the MCP CLI tests, and the duplication was
not cosmetic — each copy carried the `bun run --cwd` bug, so fixing one
left the other reading the repo's own config instead of the temp project.
That harness also swallowed spawn failures. `spawnSync` does not throw on
ENOENT or timeout; it returns `{ status: null, error }` with null stdout,
so a subprocess that never ran surfaced as `expected '' to contain
'broken'` and read like a test-logic bug. It now says the subprocess did
not complete, and why.

…fix/mcp-status-drift
`configDrift()` was read by `mcp list` and `mcp status` but never by the `/mcps` session handler, so someone debugging a server mid-session saw neither drift nor the file-scoped blank variables the CLI reported. Both surfaces answer the same "why won't this server connect" question, and the session view is the one people are actually looking at. `/mcps` now renders drift through an exported `formatConfigDriftForDisplay`, testable without standing up a session, and the response is assembled from whichever of table/drift/blanks are non-empty. `mcp-status.test.ts` drops its verbatim copy of the subprocess harness in favour of `test/cli/fixtures/isolated-cli.ts`, which also carries the `spawnSync` guard — the copy here had neither, so a spawn failure showed up as `expected '' to contain 'datamate'` with no hint the CLI never ran. Full opencode suite: 11675 pass. The single failure in that run (`opencode run` subprocess) is the known flake — `test/cli/run` and `test/session` pass 927/0 in isolation, and the failing set varies between runs.

SUGGESTION: New #878/#701 marker blocks are nested inside the #972 "shared text formatter" block, and the /** @internal Exported for tests. */ docstring is left dangling above formatConfigDriftForDisplay
The #972 block previously contained only formatMcpStatusForDisplay, whose /** @internal Exported for tests. */ docstring sat directly above it. This diff inserts the #878 and #701 blocks between the #972 opening marker (line 2900) and that function, so both are nested inside it — the same over-scoping Marker Guard checks presence but not correctness for (cf. the #878 block in discover.ts). The docstring now sits above formatConfigDriftForDisplay, which already has its own /** Config-drift lines ... */, leaving formatMcpStatusForDisplay undocumented. Close the #972 block after its docstring and place the new blocks as siblings.

Add teardown for the module-level drift store.
setConfigDrift mutates shared module state. beforeEach only resets state before a test. Add afterEach(resetConfigDrift) so each test restores the store after completion or failure.

…l gaps **The `pages: 0` later-page test could not fail.** Its only skill sat on page 1, so the buggy partial list still contained it and the assertion passed with or without the guard. The at-risk skill now lives on page 2, which is the only place the regression is observable. Mutation-verified: removing the `expectedPage !== 1` guard now fails it. That is the third vacuous test I have written this release; the test carries a note saying so. **The escaped `examples` hint broke lookup.** The model copies that hint verbatim as the `name` argument, so entity-escaping it advertised a name that would never match a real skill.

* release: v0.10.0
Add the `CHANGELOG.md` entry for `v0.10.0`, covering the 16 commits since
`v0.9.7`: the workspace surface (skill sync, derived MCP engine overlay,
warehouse tool routing, engine install offer), harness reliability, and the
corrected ChatGPT-subscription model allowlist.
The entry has to land before the tag — `script/build.ts` embeds `CHANGELOG.md`
in the compiled binary and `script/publish.ts` copies it into every npm
package, so tagging without it ships an artifact whose embedded changelog
stops at the previous version.

* fix(build): stop publishing the orphaned sourcemaps in platform packages
`Bun.build` compiles with `sourcemap: "external"`, so it writes
`index.js.map` (66MB) and `worker.js.map` (50MB) next to the binary. The
bundles those maps describe are compiled INTO the single-file executable, so
the published package carried `.map` files with no `.js` companion — unusable
by any consumer that follows `sourceMappingURL`, and not read by the binary at
runtime (verified: it runs, prints `--help` and reports errors normally with
them deleted).
They cost 20MB of a 191MB tarball, against npm's ~200MB E413 ceiling and the
release gate's 190MB threshold — which this release tripped at 191MB. Adding a
`files` allowlist to the generated platform `package.json` takes the tarball to
171MB compressed / 463MB unpacked, with both `bin/altimate` and
`bin/altimate-code` still shipped (verified with `npm pack --dry-run`).
They are still emitted, so debugging `dist/` locally is unchanged; they are
just no longer published.

* fix: close the v0.10.0 release review findings
Five-persona release review returned 4 SHIP WITH NOTES and 1 HOLD. This closes
every P0 and the actionable P1s; the rest are recorded in
`.github/meta/release-v0.10.0-findings.md` as deferred.
**Skill listing injection (P0, the HOLD).** Three sites render an
`<available_skills>` block from skill `name`/`description`. Two were escaped
when skill sync landed; `tool/skill.ts` was missed — and it is the Skill tool's
own description, sent to the model every turn whether or not the tool is ever
invoked, so it is a wider exposure than either site that was fixed. Since skill
frontmatter is now REMOTE content, a synced description ending
`</description></skill></available_skills>` broke out and arrived as prompt
text. `neutralizeListingWrapper` is now exported and both live sites route
through it, so they cannot drift apart again. Its tag list also covers
`system-reminder` and `auto_loaded_skill`: the harness uses both as trust
boundaries in the same message stream, and remote text must not forge either.
**Empty workspace never purged (P1).** `parsePage` rejected `pages < 1` as
malformed, but the server sends `pages: 0` for an empty workspace — verified
live: `{"items":[],"total":0,"page":1,"size":50,"pages":0}`. Zero skills was
therefore unobservable and the `remote.length === 0` purge was unreachable, so
a skill detached in the SaaS stayed on disk indefinitely. `pages: 0` is now
accepted only when the envelope agrees it is empty; alongside rows it is still
refused. The suite had locked the bug in by listing `0` among malformed values
and asserting it must not purge.
**Jira keys on a public repo (P1).** #1096 added three `AI-####` references to
tracked files. Replaced with the public PR number. `script/check-tracker-leaks.ts`
existed with its own tests but was wired into no workflow, which is why they
landed — it now runs on every PR.
Tests: `test/skill/release-v0.10.0-adversarial.test.ts` (7) pins the listing
escape against break-out, opening-tag forgery, trust-tag forgery, case variants,
over-escaping, and idempotence; two cases cover the real empty envelope. Both
new assertions were mutation-tested — reverting each fix fails exactly the test
written for it.

* fix(skill): delete the duplicate listing renderer, and the bug it was hiding
`src/skill/skill.ts` carried a second `<available_skills>` renderer that no
production code called — `session/system.ts` and `tool/skill.ts` both use the
one in `skill/index.ts`. Only `test/skill/fmt.test.ts` referenced it, so the
suite was exercising the dead copy while the live renderer had no coverage at
all. Deleted rather than kept in sync: two renderers is exactly how the
wrapper-tag escaping came to be applied to one and not the other.
Repointing those tests at the live renderer immediately failed, which is the
point of doing it: **built-in skills rendered a location that does not exist.**
A built-in skill's `location` is a `builtin:` URI, not a filesystem path, so
`pathToFileURL` resolved it against the CWD and emitted
`file:///…/packages/opencode/builtin:my-skill/SKILL.md`. The deleted duplicate
had a guard for this; the live renderer never did. 21 built-in skills ship, so
every session put 21 bogus paths in front of the model.
Also in this round:
- A test for the `MAX_TOTAL_BYTES` half of the sync ceiling, which had none.
The first version was vacuous — mutation showed it passed against a ceiling
with the byte term deleted, because the integrity check refuses the bundle
anyway when it advertises 16MB and serves one byte. It now asserts the
ceiling's real contract: the refusal happens on the ADVERTISED inventory, so
no file is ever requested. Re-mutated to confirm it now fails.
- `mcp status`, `--integrations` and `ALTIMATE_WORKSPACE` /
`ALTIMATE_INTEGRATIONS` were shipped but undocumented; added to the command,
flag and env-var tables.
- "Unlink the project, or run without ALTIMATE_WORKSPACE" (5 sites) did not say
whether that meant a per-session flag or a persistent variable, or whether a
restart was needed. It is read at startup, so it now says
"restart with ALTIMATE_WORKSPACE unset".

* fix: single-source the safety fraction, strip control chars from stderr notices
Two small review findings.
`compaction.ts` declared its own bare `0.65` for the context safety fraction,
cross-referenced to the `DEFAULT_SAFETY_FRACTION` exported by
`tool-result-cap.ts` by comment only. The two had already drifted apart once; a
comment cannot hold them equal, so the compaction copy now imports the exported
value. No cycle: `tool-result-cap.ts` imports nothing from `session/`.
`engine-probes.ts`'s `printLine` wrote workspace-derived text straight to
stderr. The workspace NAME is set server-side and never validated for control
characters, so a name carrying ANSI escapes could repaint or hide surrounding
output — including, in a CI log, the "engine not usable" notice this function
exists to deliver. C0 and DEL are now stripped; the newline is added by the
writer, so nothing legitimate needed them.

* fix(ci): drop the invalid `--depth=0` from the tracker-leak job's fetch
The job I added in this PR failed before it could run its own check:
git fetch origin main --depth=0
fatal: depth 0 is not a positive number
`--depth=0` is not valid git. `actions/checkout` already runs with
`fetch-depth: 0` in this job, so the clone is complete and a plain fetch of the
base ref is all the guard needs to diff against.
Verified locally: `bun script/check-tracker-leaks.ts` against `origin/main`
exits 0 on this branch, so the job should now run and pass rather than error out
during setup.

* fix(review): close the consensus-review findings — 4 major, 7 minor, 2 nit
Nearly every finding was one shape: a correct fix applied at one site and not
its sibling — the exact class this PR exists to close.
**M2 — the `builtin:` guard was applied to one of two live renderers.** I fixed
`skill/index.ts` and left `tool/skill.ts` interpolating `pathToFileURL` raw. By
this PR's own argument that is the WORSE site: it is the Skill tool's
description, sent every turn whether or not the tool is invoked. So "21 built-in
skills put bogus paths in front of the model" stayed true for the every-turn
listing. Both now share an exported `formatSkillLocation`.
**M3 — the neutralizer was bypassed by whitespace.** `<(\/?)(tag)` matched
`</description>` but not `</ description>`, `< /description>` or
`< system-reminder>`. The consumer is a language model, not an XML parser, so
those may still read as boundaries. Now a lookahead permitting whitespace, which
also leaves the surrounding text byte-for-byte intact. The test asserting
"case and whitespace variants do not slip through" contained four case variants
and no whitespace variant — the name claimed coverage it did not provide, which
is how the gap stayed invisible. Split into two honestly-named tests.
**M4 — the tests pinned the helper, not the routing.** Every test called
`neutralizeListingWrapper` directly, so reverting `tool/skill.ts` to raw
interpolation left them all passing — which is precisely how M2 survived.
Extracted `renderAvailableSkills` so the tool's listing is reachable, and both
live sites are now driven with identical hostile-metadata and `builtin:`
assertions. Mutation-verified in both directions: reverting the escaping fails
one test, removing the location guard fails the other.
**M1** was already fixed in the previous commit (`--depth=0` is not valid git).
Minors: an absent or non-numeric `total` no longer authorises a purge (m1 — a
malformed 200 could delete the snapshot AND be recorded as a successful poll);
the body escaper now shares the listing's trust-tag list, so a synced body
cannot forge a `<system-reminder>` (m2); `fmt`'s non-verbose branch is escaped
(m3); `skill.name` is escaped in the `<skill_content>` attribute (m4);
`printLine` strips BEFORE the test seam, which previously left the override exit
unsanitised entirely (m5); the CI guard gets `github.head_ref` so its
branch-name scan is not inert in a detached-HEAD checkout (m6); the dead
`pathToFileURL` import is gone and the comment no longer claims a consolidation
that did not happen (m7).
Nits: `stripControl` keeps TAB and now covers C1 (U+009B is CSI, which the
C0-only range let through) (n1); recorded why `location` is in the tag list but
not routed through the neutralizer — `pathToFileURL` percent-encodes `<`/`>`
(n2).
Also fixes a marker-integrity break of my own: `engine-probes.ts` had 2
`altimate_change start` against 1 `end`. `analyze.ts --markers` did not catch it
because that check covers only upstream-shared files; the real check lives in
`test/upstream` and `test/branding`, which CI runs and I had not.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): mark the non-verbose fmt escaping for the upstream-shared marker guard
The marker guard diffs committed state against origin/main, so the escaping
added to `fmt`'s non-verbose branch needed its own altimate_change markers in
a commit before the check could see them.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): two regressions the bot reviewers caught in my own review fixes
**The widened body escaper corrupted shipped skills.** Sharing the listing's
tag list with `neutralizeSkillWrapper` meant skill BODIES had their structural
tags escaped too — and `.opencode/skills/` ships **117** legitimate `<name>`
occurrences across dbt-docs, dbt-develop and sql-review. Every auto-loaded
builtin skill would have had them rewritten to `<name>`. In a listing those
tags are structure; in a body they are content. Narrowed back to the two actual
trust boundaries, `auto_loaded_skill` and `system-reminder`, which is what that
escaper is for.
**`PR_BRANCH` did nothing.** I added the env var to the workflow so the guard's
branch-name scan would work in a detached-HEAD PR checkout, but never taught
`check-tracker-leaks.ts` to read it — its only `process.env` reference was
`SKIP_TRACKER_CHECK`. The scan stayed inert, which is exactly the gap the
change claimed to close. The script now prefers `PR_BRANCH`; verified by
running it with a tracker-shaped branch name, which now exits 1 where it
previously passed.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): close the remaining bot-review findings
Several are the same one-site-not-its-sibling shape this release keeps tripping
over — including two where I fixed a line and missed its neighbour.
- `# Skill: ${skill.name}` sat one line below the `<skill_content>` attribute I
had just escaped, still interpolating the same attacker-influenced
frontmatter raw. So did the `examples` hint that seeds the tool description.
Both now escape.
- Attribute escaping handled `"` but not `&`, so a name containing the literal
text `"` survived and the consumer decoded it back into a real quote that
closes the attribute — the exact break-out the escaping exists to stop.
Extracted `escapeSkillAttr`, which escapes `&` first.
- `<built-in>`, the sentinel location for embedded skills, is no more a
filesystem path than `builtin:` is; it was still being run through
`pathToFileURL` into a URL that does not exist.
- An empty page with a negative or NaN `total` still authorised the purge; the
gate now requires an integer zero.
- `pages: 0` arriving on a LATER page contradicts the page count page 1 gave.
Accepting it made `listAll` stop early and return a PARTIAL list as though it
were the whole workspace, pruning everything past page 1. Restricted to the
first page.
- The tracker-leak job now runs with `permissions: contents: read` and
`persist-credentials: false`: it executes pull-request code and should not
have a token sitting in `.git/config`.
- `--integrations` sets a process-wide env var that children inherit; the docs
said "for this session".
- `mcp status` moved out of "Added" — this release documented it, it did not
add it.
- Refreshed the adversarial test header, which still described the duplicate
`Skill.fmt` that this release deleted.
Tests cover the `&`-before-`"` ordering, both location sentinels, and the
later-page `pages: 0` case.

* fix(review): second bot round — a vacuous test of mine, and three real gaps
**The `pages: 0` later-page test could not fail.** Its only skill sat on page 1,
so the buggy partial list still contained it and the assertion passed with or
without the guard. The at-risk skill now lives on page 2, which is the only
place the regression is observable. Mutation-verified: removing the
`expectedPage !== 1` guard now fails it. That is the third vacuous test I have
written this release; the test carries a note saying so.
**The escaped `examples` hint broke lookup.** The model copies that hint
verbatim as the `name` argument, so entity-escaping it advertised a name that
would never match a real skill. It now strips angle brackets instead, which
keeps the injection surface closed without inventing an unusable name — the
authoritative listing is escaped either way.
**`stripControl` let U+2028/U+2029 through.** Neither is C0 or C1, but both are
Unicode line separators and still break the one-notice-per-line framing that
writer depends on.
**Restored the `#1160` reference** dropped when `mcp status` was folded from

* fix(review): the examples hint must be copyable, not sanitised
The previous attempt at this line was wrong twice over, as the bot review
pointed out:
- Its justification was inaccurate. `isSkillFrontmatter` only requires
`typeof data.name === "string"`, so a synced skill's name CAN contain `<`/`>`.
- `replace(/[<>]/g, "")` therefore overcorrected: `foo <bar>` rendered as
`foobar`, which no longer matches on `Skill.get` — reintroducing, for every
legitimately bracketed name, the exact lookup mismatch the change was meant
to fix.
The hint is copied verbatim by the model as the `name` argument, so it has to
match the real skill. That rules out escaping it and rules out stripping. It now
advertises only names the neutralizer would leave untouched — precisely the set
that is both copyable and free of trust-tag text. Every skill still appears in
the authoritative listing above, escaped.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): close the human review — 1 critical, 2 major, 1 minor
**CRITICAL — the rendered skill BODY was completely unescaped.** `skill.name` was
escaped on the two lines above it and `skill.content.trim()` went out raw, as did
each `<file>` path. For a workspace-synced bundle that body is remote content, so
it could close `</skill_content>` and continue as post-skill tool output, or forge
a `<system-reminder>` verbatim — the exact forgery `neutralizeSkillWrapper` was
extended to stop on the auto-load path. This path is the WIDER of the two: the
auto-load path needs `alwaysApply` or a matching glob, this one is what any skill
reaches on demand.
`neutralizeListingWrapper` could not be reused: its `skill\b` alternative does not
match `skill_content`, because `\b` fails between the `l` and the `_`. So the body
gets its own tag set — `skill_content`, `skill_files`, `file`, `auto_loaded_skill`,
`system-reminder` — via `neutralizeBodyWrapper`, applied to the body and to every
bundle file path (`safeRelativePath` rejects `..`, absolute paths and NUL, but
permits `<` and `>`).
**MAJOR — `<built-in>` made the built-in skill scan the user's project.**
`isBuiltin` tested only `startsWith("builtin:")`, so for the `customize-opencode`
skill registered with `location: "<built-in>"`, `path.dirname()` returned `"."`
and `Ripgrep.files({ cwd: "." })` ran over the whole project, emitting up to ten
of the user's file paths inside `<skill_files>` for a skill that has no files.
Third site of this same fix, so it now goes through one predicate:
`classifySkillSource`, which also learned `<built-in>`.
**MAJOR — `parsePage` was one-directional.** The guards rejected `pages: 0` unless
the envelope agreed it was empty, but not `total: 0` with `pages > 1`. A
`{items: [], total: 0, pages: 3}` envelope was accepted, `listAll` returned `[]`,
and the snapshot was purged on a malformed 200 — the one outcome this parser's own
comment says it exists to prevent. Now symmetric.
Tests: body break-out, forged `system-reminder`, the `skill_content` underscore
case (asserting the listing pattern genuinely does not cover it), file-path
forgery, an over-escaping guard, both location sentinels, and the mirror
`total: 0` / `pages > 1` envelope. Every new guard mutation-verified — the
symmetric one initially had NO covering test and the mutant survived, so the
mirror test was added and re-checked.

* fix(build): use `!bin/**/*.map` so the exclusion descends
`*` does not descend, so a sourcemap emitted under `bin/<subdir>/` would still
have shipped despite the exclusion added earlier in this PR. Also records the
tradeoff the allowlist introduces: any future artifact added outside `bin/` is
now silently dropped from the published package.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): third bot round — a regression of mine, plus a live break-out
**`isBuiltin` suppressed real skill directories (P1, my regression).** Routing it
through `classifySkillSource` was wrong: that answers "who shipped this" and
returns "builtin" for skills that DO live on disk (`~/.altimate/builtin`,
Altimate-owned `node_modules`). Their resource directories were suppressed and
their bundled files omitted, breaking relative references. The question here is
"does this have a filesystem directory", which only the two sentinels answer —
now `Skill.hasNoSkillDirectory`, shared with `formatSkillLocation` since both ask
the same thing and drifted apart once already.
**One neutralizer implementation, several tag sets (P2).** `makeWrapperNeutralizer`
now backs the listing escaper, the body escaper and `system.ts`'s auto-load
escaper. Adding a trust boundary means adding it to a list rather than
remembering to patch a third regex — which is how the body escaper shipped
without `system-reminder`. The sets stay separate deliberately: the listing's
structural tags must not be escaped inside a body, where `.opencode/skills/`
ships 117 legitimate `<name>` occurrences. Patterns are built once per set rather
than per call.
**The body render site is now testable, and testing it found a live bug (P3).**
The previous tests pinned `neutralizeBodyWrapper` but not the site that calls it —
the same gap that let the critical through, so `renderSkillContent` is extracted
the way `renderAvailableSkills` was. The new render-site test failed immediately:
a hostile skill NAME ending `</skill_content>` broke out of the block, because
the heading used the LISTING neutralizer and its `skill\b` alternative does not
match `skill_content`. The heading now runs through both sets.
Mutation-verified: removing the body escaping from the render site fails the new
test.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): pin the call sites, split the file tag set, refuse any empty later page
**Call sites, not helpers — the third time this was raised, and it was right each
time.** Asserting `hasNoSkillDirectory("<built-in>")` stays true even if the site
stops calling it, which is exactly how the previous regression there went
unpinned; the same held for the `<file>` escaping. `resolveSkillBase` and
`renderSkillFileEntry` are now extracted and driven directly by tests. All three
fixes in this commit are mutation-verified: reverting the `<file>` escaping,
reverting `isBuiltin` to the classifier, or dropping the empty-page guard each
fails a test.
**`file` no longer escapes prose.** `neutralizeBodyWrapper` ran over both the
body and the generated `<file>` entries, so it had to satisfy both — but in a
body `<file>` is ordinary documentation (`cat <file>`, or any Maven / log4j /
`.csproj` snippet). That is the same over-correction that kept `name` out of the
body set. `file` moves to `FILE_PATH_BOUNDARY_TAGS`, used only for the generated
path entries. No shipped `SKILL.md` contains any of the five tags today, so this
was latent rather than live.
**Any empty page after page 1 is refused, whatever `pages` claims.** The previous
guard only caught `pages: 0`. `{items: [], total: 0, page: 2, pages: 1}` slipped
through: `listAll` stopped on `page >= pages` and returned only page 1's rows as
though they were the whole workspace, pruning everything on later pages.

* fix(review): require a real tag delimiter, plus two tidy-ups
**`\b` also sits before `-`,** so `<name-value>`, `<file-path>` and
`<description-list>` were escaped as though they were wrapper tags. The pattern
now requires a real delimiter after the tag name — `\s*(?:[/>]|$)` — which keeps
legitimate hyphenated markup intact while still catching `<name>`, `</ name >`
and the genuinely hyphenated `<system-reminder>`. Mutation-verified: restoring
`\b` fails the new cases.
Also: aligned the `resolveSkillBase` call to its enclosing block, and merged the
duplicate `../../src/tool/skill` import in the adversarial test.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(review): whitespace terminates a tag — restore attribute-bearing escaping
The previous commit's comment said `[\s/>]` and its code said `\s*(?:[/>]|$)`.
Those are not the same: the first accepts whitespace as a TERMINATOR, the second
SKIPS whitespace and then demands `/`, `>` or end-of-input. So every
attribute-bearing wrapper tag stopped matching — including the exact forms this
codebase emits, `<skill_content name="...">` and `<auto_loaded_skill name="...">`.
Remote skill text could forge either verbatim. That regressed the critical
finding this PR exists to close, one commit after closing it.
Root cause of it going unnoticed: every hostile fixture in the suite used a BARE
tag (`</skill_content>`) or an obfuscated one (`</ description>`), so a change
that broke only the attribute-bearing shape was invisible. Added fixtures for the
authentic shapes; the suite now pins the delimiter from BOTH sides —
mutation-verified that restoring either the broken form or the original `\b`
fails a different test.
Also folds the skill-name escaping onto a single `SKILL_NAME_TAGS` set instead of
chaining two neutralizers, since "apply both to be safe" is what produced the
wrong-set bug a round earlier.

* fix(review): pagination invariants across pages, plus the remaining review items
**Two ways a malformed listing could delete the user's synced skills.**
`parsePage` validated `total` only on EMPTY pages, so `{items: [A], total: 0}` —
a self-contradiction — was accepted as the complete workspace and every other
skill was pruned. And nothing tied later pages to page 1: page 1 could say
`pages: 3`, page 2 could say `pages: 2`, `listAll` would stop on
`page >= pages` having never fetched page 3, and everything on page 3 was pruned.
Neither needs an attacker — a caching layer or a backend bug is enough, and the
failure mode is silent deletion.
Pagination is now stateful: page 1 establishes `pages` and `total`, every later
page must repeat them, a non-empty page must carry an integer `total` that is at
least its own row count, and the echoed `page` must be PRESENT and numeric —
"absent" previously meant "unchecked", which let a cached page-1 body stand in
for page 2.
**Review items.** The auto-load escaper had a hand-picked two-tag list that
silently omitted `skill_content`/`skill_files`; it now shares
`BODY_BOUNDARY_TAGS` with the on-demand renderer. The `examples` filter used the
listing set, so a name carrying `</skill_content>` passed it and reached the
tool's parameter description verbatim; it now uses `neutralizeSkillNameText`, and
is extracted as `selectExampleNames` so the FILTER is pinned rather than the
helper it calls — the first version of that test passed with the filter reverted.
Narrowed the `SKILL_NAME_TAGS` doc comment, which claimed every name site uses
that set when only two do.
**Deliberately NOT changed:** the listing set keeps `skill_content`/`skill_files`
out. A static sweep recommended adding them; the human review argued that in a
listing those are not boundaries and escaping them inside a `<name>` would mangle
a legitimate skill name for no gain. Going with the reviewer, and recording the
disagreement rather than silently picking a side.
Tests: non-empty page with a contradictory total, a later page lowering the page
count, a missing echoed page, the name set covering both boundary families,
newline/CR/VT/FF attribute separators, self-closing with an attribute, and the
examples filter in both directions. Every new guard mutation-verified
individually.

Issue for this PR
Closes #790
Closes #878
Type of change
What does this PR do?
1. Adds
mcp status(#790).statusis the name people reach for when a server won't connect, and it was the one name that didn't exist.Being straight about the size of this: the gap was narrower than the issue implies.
mcp listalready probed live (mcp.status()initialises the MCP service) and already printed the failure reason. The missing piece was the entry point, not the view — sostatusshares that handler rather than duplicating a view that would then need keeping in sync.It's a sibling command rather than an alias because
aliases: ["ls", "status"]widened yargs' alias column enough to rewrap an unrelated row (mcp auth listlost its[aliases: ls]onto a second line). As its own command the help output stays additive — the diff against the committed snapshot is exactly one added line.2. Reports discovered-config drift (#878). Discovery is first-source-wins, so a server already in the user's config is skipped outright, and a changed
.vscode/mcp.json— a newALTIMATE_EXTENSION_RPCport, a moved command — was never mentioned.driftFields()now reports which fields disagree, naming nested keys individually (environment.ALTIMATE_EXTENSION_RPC) so the message points at the thing to fix rather than justenvironment.enabledis excluded, since discovery sets it for its own reasons.The configured value still wins. This reports the disagreement and where to look, and leaves the decision to the user — silently overwriting someone's own config would be worse than the silence it replaces. That's the "detect and report" option of the three the issue offered.
How did you verify your code works?
opencodesuite: no regressions.HOMEplus a temp project containing a drifted.vscode/mcp.json, asserting both that the drifted field is named and that an agreeing config stays silent.statusregistration, each fails exactly one test.origin/main; typecheck clean.Flaky tests, flagged rather than hidden: the subprocess-heavy suites (
test/pty,test/cli/run) fail intermittently under parallel load — different tests each run, all passing across repeated isolated runs. These flakes pre-date this PR, but it does make them more likely to surface: it adds two more e2e files that each spawn real CLI subprocesses.Test-harness fix worth knowing about: the e2e pattern copied from
mcp-add.test.tsusesbun run --cwd <pkg>, which makes the CLI's working directory the repo package — so it read the repo's own.opencodeconfig and never saw the temp project, meaning discovery never ran and the drift assertion couldn't fire. Fixed here by setting the spawn cwd to the project.mcp-add.test.tsis unaffected in practice (it passes--global), so it's left alone.Screenshots / recordings
Not a UI change.
