Add single-flight loading for concurrent cache misses.
When projectContext is enabled, concurrent Command Code requests for the same cwd can each start collectProjectContext. Each collection performs bounded but independent filesystem reads and directory scans. The cache is populated only after collection completes, so the existing TTL does not prevent duplicate work during a cold or expired-cache burst.
Store the in-flight promise by cwd and remove it in finally, including when collection fails. Update the capacity test to reflect the shared collection.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Check whether the cache key exists when inserting, not before collection.
hadCachedEntry is set at Line 437, before collectProjectContext runs. That call can take up to COMMAND_CODE_FILE_OP_TIMEOUT_MS (2 s). The branch at Lines 445-449 then uses this old value, so the cache can grow past MAX_PROJECT_CONTEXT_CACHE_ENTRIES.
How the cap is exceeded:
- The cache holds 127 live entries and one expired entry
K. - A request for
Kstarts.hadCachedEntryistrue. - While
Kis still loading, a request for a new keyLfinishes.pruneProjectContextCacheremoves expiredK. The size drops to 127, so nothing is evicted, andLis inserted. The size is now 128. - The
Kload finishes.hadCachedEntryis stilltrue, so onlypruneExpiredProjectContextCacheruns and removes nothing.projectContextCache.set(cwd, …)addsKback. The size is now 129.
Each time this interleaving repeats, the cache can gain one more entry above the cap. This breaks the "128-entry cache" limit documented in structure/providers-and-adapters.md Line 263.
The stale flag also causes unneeded evictions. When two requests miss on the same new key at once, both see hadCachedEntry === false. The second insert then runs pruneProjectContextCache at full capacity and evicts a live sibling, even though it only overwrites an existing key.
Fix: evaluate projectContextCache.has(cwd) right before the prune decision. The test "refreshing an expired cached key does not evict a live sibling at capacity" still passes. The first refresh prunes the expired root and re-inserts it. The second refresh only overwrites it.
🐛 Proposed fix
- const hadCachedEntry = projectContextCache.has(cwd);
const cached = projectContextCache.get(cwd);
if (cached && Date.now() - cached.collectedAt < PROJECT_CONTEXT_TTL_MS) {
return cached.value;
}
const value = await collectProjectContext(cwd, fileOpTimeoutForTests ?? COMMAND_CODE_FILE_OP_TIMEOUT_MS);
const now = Date.now();
- if (hadCachedEntry) {
+ // Re-check at insertion time: another load may have evicted or inserted this key meanwhile.
+ if (projectContextCache.has(cwd)) {
pruneExpiredProjectContextCache(now);
} else {
pruneProjectContextCache(now);
}
projectContextCache.set(cwd, { collectedAt: now, value });Add a regression test in tests/providers/command-code-project-context.test.ts. Hold the K read open with the gated openMock pattern from Lines 808-830. Complete a load for a new key while it waits. Then assert that projectContextCache.size is at most 128.

Reviewed exact head 4ba1e1c. Concurrent cold or expired-cache requests for the same cwd each run the full directory traversal because the cache is populated only after collection completes. The timeout uses Promise.race, but it cannot cancel lstat/realpath/opendir work already dispatched. On slow or stuck FUSE/NFS paths, repeated requests can therefore accumulate duplicate pending filesystem operations and consume I/O workers/file resources even after callers time out.
Add a cwd-keyed single-flight so one bounded scan serves concurrent requests, and give timed-out scans a bounded lifecycle/admission policy that prevents unbounded abandoned work. Cover concurrent cold-cache calls and a never-settling filesystem operation. Exact-head CI also currently has a test 2/4 multi-file process-state timeout, so this head is not approval-ready.

@Ingwannu Addressed your current-head review in commit Cold/expired requests for one cwd now share one in-flight scan. A scan keeps its cwd admission slot after a caller timeout until every dispatched filesystem promise settles; at most eight scan slots and 64 pending operations are admitted. New requests fail soft when those limits are reached. Cache insertion now prunes and checks capacity against the current map immediately before setting the value, so an intervening eviction cannot exceed 128 entries. Added concurrent cold-cache, never-settling cross-cwd, and cache-eviction interleaving regressions. Local tests remain skipped by release-train instruction; exact-head GitHub CI is running. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Symlinked skill directories are silently skipped, even when their target is inside cwd.
entry.isDirectory() on a Dirent from opendir reports the entry itself. It does not report the symlink target. A directory symlink therefore returns false here, and .commandcode/skills/foo -> ../../.agents/skills/foo is dropped before confinedCanonicalPath runs.
Linking one skill directory into several agent-specific roots is a common install layout. With that layout, a skill under .commandcode/skills becomes invisible when it is a link. confinedCanonicalPath(skillMd, cwdCanonical, ..., "file", ...) at Line 336 already resolves SKILL.md through realpath, enforces containment, and checks the file type. openedFileIsConfined then checks the inode again. Accepting symlink entries here does not weaken confinement. An escaping target is still rejected.
🐛 Proposed fix
- if (!entry.name.startsWith(".") && entry.isDirectory()) {
+ // Symlinked skill dirs are allowed; confinedCanonicalPath resolves and confines SKILL.md.
+ if (!entry.name.startsWith(".") && (entry.isDirectory() || entry.isSymbolicLink())) {Add a test in tests/providers/command-code-project-context.test.ts for both cases. An in-cwd directory symlink must be included. An outside-cwd directory symlink must still be omitted.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Do not cache a result produced by a timeout or an admission refusal.
collectProjectContext turns every failure into an empty field. This includes a deadline timeout in withinDeadline, the "project context filesystem admission limit" error thrown at Line 93, and a null from canonicalPath(cwd) at Line 471. The scan at Lines 499-506 then stores that result in projectContextCache for the full PROJECT_CONTEXT_TTL_MS (30 s).
How the failure happens:
- With
projectContext: "on", a request arrives while the filesystem is briefly slow (for example, a cold NFS mount, or AV scanning on Windows). A request can also arrive while other scans hold most of the 64 pending-operation slots. canonicalPath(cwd, ...)times out after 2 s, or one of the reads is refused.collectProjectContextreturns{ memory: "", taste: null, skills: null }or a partial result.- Lines 502-504 cache that value. For the next 30 s, every generation request sends empty or partial context. This happens even though a new scan would succeed.
The proxy normally runs in one process working directory (currentWorkingDirectory() in src/adapters/command-code.ts). One slow scan therefore disables project context for every request in that window, and the user sees no signal.
A genuinely missing file is a stable result and can be cached. A timeout or a refused operation is transient and must not be cached. Record degradation on the ScanScope, and skip the cache insert when the flag is set.

Track transient timeouts and filesystem admission refusals as degradation on
ScanScope, including failures handled by withinDeadline and readUtf8File, then
skip the projectContextCache insert in the scan flow when degraded; continue
caching stable missing-file results. Add a regression test that stalls lstat
once and verifies a subsequent load returns the real AGENTS.md content without
clearing the cache.

Hanging-operation tests leak module-level scan slots forever. Later tests then depend on test order.
In "times out a hanging skill directory iteration" (Lines 289-321), next: () => new Promise<never>(() => {}) never settles. The same applies to read: () => new Promise<never>(() => {}) in "times out and closes a hanging file read" (Lines 509-539). trackedFileOperation counts each such operation in scope.pendingOps and pendingProjectContextFileOps. releaseScanIfSettled therefore never removes the scope from outstandingProjectContextScans. Each test leaves one of the 8 MAX_CONCURRENT_PROJECT_CONTEXT_SCANS slots occupied, plus several global pending operations, for the rest of the process.
The suite passes only because "never-settling scans retain their cwd slots" (Line 169) runs before these tests and expects exactly lstatCalls === 8. If the tests are reordered, run in randomized order, or run with --rerun-each, that test sees only 6 free slots and fails. Other tests that share the module can also start hitting the fail-soft path.
The tests at Lines 95-136 and 169-196 already release their stalled promises in finally. Apply the same pattern here:
♻️ Proposed fix
let closeCalls = 0;
+ let releaseNext: () => void = () => {};
const hangingDir = {
close: async () => {
closeCalls++;
},
[Symbol.asyncIterator]() {
return {
- next: () => new Promise<never>(() => {}),
+ next: () => new Promise<IteratorResult<never>>(resolve => {
+ releaseNext = () => resolve({ done: true, value: undefined as never });
+ }),
};
},
};
...
} finally {
+ releaseNext();
+ await new Promise<void>(resolve => setTimeout(resolve, 0));
opendirMock.mockImplementation(realOpendir); let closeCalls = 0;
+ let releaseRead: () => void = () => {};
const hangingFile = {
stat: async () => statSync(agentsPath),
- read: () => new Promise<never>(() => {}),
+ read: () => new Promise<{ bytesRead: number; buffer: Buffer }>(resolve => {
+ releaseRead = () => resolve({ bytesRead: 0, buffer: Buffer.alloc(0) });
+ }),
...
} finally {
+ releaseRead();
+ await new Promise<void>(resolve => setTimeout(resolve, 0));
openMock.mockImplementation(realOpen);After the tests release their operations, you can also assert that no slot remains occupied. For example, a later loadCommandCodeProjectContext(root) on the same root must return real content.

Update the hanging-operation tests for skill directory iteration and file reads
to use controllable promises instead of promises that never settle. In each
test’s finally block, release the stalled operation and allow it to settle
before restoring mocks and cleaning up, so scan slots and pending-operation
counts are cleared regardless of test order.

Re-reviewed exact head 8ca9b73bcd37021fdb79aab0cabc97580936464b. The same-cwd single-flight and global admission caps fix the prior unbounded duplicate-scan blocker, but three P2 issues remain. (1) listSkillDirs accepts only entry.isDirectory(), so a symlinked skill directory never reaches the existing confined canonical-path check; allow symlink entries through that confinement and test in-cwd include/out-of-cwd reject. (2) timeout or filesystem-admission degradation returns empty fields and is inserted into the 30-second cache at lines 499–505, hiding a healthy retry after a transient stall; mark the scan degraded from withinDeadline/read admission and skip cache insertion for degraded scans while still caching stable missing files. (3) the hanging-operation tests use never-settling promises and restore mocks without releasing them, permanently retaining scan/file-op slots in the process and making later tests order-dependent. Use controllable promises and release/settle them in finally. Exact-head functional CI is otherwise green; please fix these and rerun.

Summary
Carries #4228 by @yansigit. A provider using the native
command-codeadapter may setprojectContext: "on"to place bounded local context in the/alpha/generatememory,taste, andskillsfields. WithprojectContextoff, no project files (AGENTS.md, taste, or skills) are read or sent; the existingconfigmetadata payload is unchanged. Config load and management writes reject this field on other adapters; the management editor policy includes it.The loader reads
AGENTS.md,.commandcode/taste/taste.md, and immediate childSKILL.mdfiles under.commandcode/skills,.agents/skills, and.pi/skills, all relative to the OCX proxy process working directory. That directory is not automatically the caller's remote workspace. Enabling the option sends these local file contents upstream to the configured Command Code endpoint. Asynchronous path checks under one deadline, regular-file checks before nonblocking opens, filesystem-root-safe containment, per-file and total skill-byte limits, a per-root entry scan cap that counts hidden and nonmatching entries, a separate 16-skill selection limit, and timeout cleanup bound the load. Failed reads are omitted; a TTL/capacity cache bounds repeated loads.Compared with #4228, this carry adds a total skill-read budget, provider-scoped validation, exact adapter-envelope fixture assertions, a byte-budget regression, exhaustive model-rename classification, and ownership documentation. The follow-up at
fa4d4fad0dmoves metadata checks to asynchronous calls within one deadline, rejects non-regular files before reads (with nonblocking POSIX opens and anfstatcheck), and handles filesystem roots in path containment. It retains the contributor's mixed-entry iterator test, valid-directory positive control, resolved-name precedence test, and loader-driven cache eviction test.Co-authored-by: SB Yoon 44089734+yansigit@users.noreply.github.com

No project-file bytes are returned unless the opened descriptor’s device/inode matches a fresh regular-file
lstat, its path still resolves to the same canonical file inside the proxy cwd, and those checks pass again after the read. This catches an intermediate skill directory swapped to an outside symlink between the initial check andopen(); a deterministic regression performs that swap. POSIX opens also useO_NOFOLLOW | O_NONBLOCK. Windows retains best-effort path and descriptor identity checks.Concurrent cold or expired loads for one cwd share a single scan. Eight cwd scan slots remain occupied until all dispatched filesystem operations settle, even after a caller timeout; a 64-operation ceiling prevents unbounded abandoned work. Requests above either limit return empty context without starting another scan. Cache capacity is checked again immediately before insertion, so an intervening eviction cannot push it above 128 entries. Focused regressions cover same-cwd concurrency, never-settling filesystem work across cwds, and insertion after eviction. Symlinked skill directories are resolved through the same cwd confinement check: inside targets load, outside targets are rejected. Timeout or admission-degraded scans are not cached, allowing a healthy retry; stable missing-file results remain cacheable. Test deferrals settle and release their scan slots in teardown.
Enabling
projectContextsends localAGENTS.md,.commandcode/taste/taste.md, and skillSKILL.mdcontents upstream to Command Code. The literal per-provider"on"gate is the only path into the loader; withprojectContextoff, no project files (AGENTS.md, taste, or skills) are read or sent and the existingconfigmetadata payload is unchanged. File reads are confined to the canonical proxy cwd and bounded by path, entry, skill, byte, time, and cache limits. This is an outbound local-content boundary; maintainer security review and sponsorship remain required.Checklist
