fix(init): keep user files in legacy command folders - #1874
Conversation
Legacy cleanup removed each pre-skills tool's <tool>/commands/openspec/ folder recursively whenever it existed, deleting any command the user kept there along with OpenSpec's three files. init runs that cleanup unprompted when there is no TTY, so agents and CI lost those files without --force. Directory entries now name the files OpenSpec wrote there. Cleanup deletes only those, removes the folder only once nothing else is left in it, and reports each entry it kept. A folder holding none of OpenSpec's files is no longer treated as legacy, and a folder holding only them is removed exactly as before.
📝 WalkthroughWalkthroughLegacy cleanup now identifies OpenSpec-managed files by filename and markers. It preserves user files, avoids symlink traversal, removes directories only when empty, reports retained files, and updates related tests and changeset documentation.

Legacy cleanup treated any regular file named proposal/apply/archive in a <tool>/commands/openspec/ folder as OpenSpec's, so a user-authored file with one of those names, including one swapped in while the upgrade prompt waited, was still deleted. Every legacy slash command was generated with the OpenSpec markers, and OpenSpec refused to update one without them. A file now counts as OpenSpec's only when its content still carries them, and cleanup checks that again immediately before each unlink. A symlinked command folder is never followed. Test fixtures now use marker-wrapped content like the real generated files. Closes Fission-AI#1873 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Second pass, answering CodeRabbit's outside-diff finding at Fixed in cf9e9cc: each file in the directory loop is now checked for the OpenSpec markers immediately before its unlink. Only files that pass are recorded as deleted; a file that fails is left in place, so the folder is not removed and the file is reported under "Kept".

Legacy cleanup now identifies OpenSpec-owned files by both name and markers, rechecks ownership before unlinking, never follows linked command folders, and removes directories only when empty. Focused cleanup and update tests pass; the current canonical docs remain accurate because they do not promise recursive legacy-folder deletion.
…ks (Fission-AI#1905) isGeneratedLegacyCommand lstat'ed a path and then re-read it by path, so the file judged "generated" could differ from the file read (CodeQL js/file-system-race, alert Fission-AI#524, added by Fission-AI#1874). Open once with O_NOFOLLOW|O_NONBLOCK, fstat that handle, and read from it. Windows lacks O_NOFOLLOW, so links are still refused there via lstat. Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
Closes #1873.
Why
Six entries in
LEGACY_SLASH_COMMAND_PATHS(src/core/legacy-cleanup.ts:36-41)were
directoryentries: Claude Code, CodeBuddy, Qoder, Lingma, Crush andGemini CLI, each at
<tool>/commands/openspec/. Detection flagged the folderwhenever it existed (
:321-323). Cleanup then ranfs.rm(fullPath, { recursive: true, force: true })(:555), deleting everythingin it. Users keep their own commands in that folder, and they went with
OpenSpec's three old ones:
to preserve".
✓ Removed .claude/commands/openspec/.So nothing ever told the user their files had been in it.
openspec initruns this cleanup automatically when--forceis set or whenthere is no TTY (
src/core/init.ts:500-501). So an agent or CI running plainopenspec init --tools claudedeleted the files without a prompt.openspec update --forceuses the same function.The file already names the hazard for CoStrict (
:69-71), which #1492 madefile-scoped. The directory entries never got the same treatment.
What Changes
managedFileNames. The names come from the slash configurators removed infeat(cli): merge init and experimental commands #565:
proposal.md,apply.mdandarchive.md, or.tomlfor Gemini.Lingma is the exception. Its support arrived after the opsx rename and has
always written to
.lingma/commands/opsx/, so OpenSpec never wrote a fileinto
.lingma/commands/openspec/, and its list is empty.exactly as before.
one by one. The upgrade prompt then lists exactly what will be deleted.
non-recursive
rmdir, and only if the folder is empty. Anything left isrecorded in a new optional
CleanupResult.keptFilesand printed as• Kept .claude/commands/openspec/team-review.md (not created by OpenSpec).This also protects a file added between detection and cleanup, for example
while the interactive prompt waits.
getToolsFromLegacyArtifactsandomitToolLegacyArtifactstreat them like anyother legacy file. The second is what the legacy-upgrade path uses to skip a
tool whose replacement was not written.
The common upgrade is unchanged: a folder holding only OpenSpec's files is
removed as before, with the same prompt line and the same summary line.
Testing
New file
test/core/legacy-cleanup.user-files.test.ts, now 30 tests. The first24 were written first: on clean
9d4e597they gave 15 failed and 9 passed, everyfailure a bug assertion and every control passing. The later ownership and
recheck tests each fail without the change that added them. With the fix, all 30
pass.
Edge cases covered:
OpenSpec files is still removed (control). A user file in it is kept, the
OpenSpec files are deleted, the folder stays, and the files map back to the
tool.
legacy file (
apply.md/).proposal.mdis kept whileproposal.tomlis removed.beside OpenSpec's files, and a symlinked command folder is never followed.
proposal.mdthe user swaps in between detection and cleanup, or aftercleanup has scanned the folder, is kept and reported as kept.
what was kept and never claims the folder was removed.
omitToolLegacyArtifactsskips the tool, a mixed folder is untouched.openspec init --tools claudekeepsteam-review.md, bothwithout a TTY and with
--force. It still removes a folder of only OpenSpecfiles.
Two existing tests encoded the old behaviour and were updated:
test/core/update.test.ts› "should cleanup legacy slash commanddirectories with --force". Its fixture was
old-command.md, a file OpenSpecnever wrote, and it asserted that such a file is deleted along with the folder.
That is the behaviour this PR removes. The fixture is now
proposal.md, andthe assertions are unchanged.
test/core/legacy-cleanup.test.ts› "should include expected toolpatterns". It compares the claude entry with
toEqual, so it now includesmanagedFileNames.Verification
