Review comments at @src/services/skills/__tests__/SkillsManager.spec.ts:
- Around line 736-794: Extend the depth-limit test around
SkillsManager.discoverSkills with a fixture placing a skill in a container at
depth 5, and assert that it is discovered. This should distinguish the inclusive
depth-5 boundary from a guard that stops scanning when depth is greater than or
equal to 5.
Review comments at @src/services/skills/SkillsManager.ts:
- Around line 98-102: Update scanSkillsDirectory to track visited directories by
real path and skip directories already encountered, passing the same set through
recursive calls. Create a fresh visited set for each top-level scan so traversal
remains deduplicated without sharing state across source or mode roots.
- Around line 93-102: Update loadSkillMetadata to preserve the first skill
stored under a colliding source:mode:name key: check whether skillKey already
exists and return without replacing it; otherwise keep the existing insertion
behavior.

it was visited. Skip a directory only when its recorded depth is no deeper than

104-114: Keep the first skill when a nested name collides.The recursive branch on Line 113 can find two skills with the same leaf name in different containers, such as
repo-a/fooandrepo-b/foo.loadSkillMetadatasaves both under the samesource:mode:namekey on Line 201. The second skill found replaces the first one.getSkillContentand the prompt listing look up skills by leaf name only, so users can no longer reach the replaced skill. An earlier review reported this issue, and the current code still has it.This fix also stops a later root at the same source and mode from replacing an earlier one. The comment at Lines 620-627 says the later root should win, so
.roostill takes priority over.agents. To keep that rule, track the keys seen in each root scan and apply the first-wins check only inside one root scan.

Fixed relevant pre-merge check. "Security Boundaries" check is not relevant because in this case it's not realistic that attacker having access to symlink may cause more problems than he can already. |

📓 Common learnings
Learnt from: p12tic
Repo: Zoo-Code-Org/Zoo-Code
Timestamp: 2026-09-28T21:10:04.640Z
Learning: In `src/services/skills/SkillsManager.ts`, a first-level symlink under a configured skills root is intentionally trusted to support skill discovery in symlinked containers. For PR #1843, pointing that symlink at a very large directory is treated as user configuration error; a directory-visit budget is not required for this change.

sourceDirsymlink before theEXDEVcopy.A direct skill can itself be a symlink, such as
.roo/skills/foo -> ../../shared/foo. Discovery stores that skill's path asrealDirPath/foo/SKILL.md.sourceDiris therefore the link itself, and it passes therealSourceRootcheck.On
EXDEV,fs.cp(sourceDir, stagingDir, { verbatimSymlinks: true })takes the source's stats withlstat, becausedereferenceis false. Node then copies the link itself, with the same relative target text. The copied link resolves against a different parent directory, so it dangles.
findEscapingRelativeSymlink(stagingDir)does not detect this case. It callsreaddir(stagingDir), which follows the link, and it inspects only the entries under the link. It never inspectsstagingDir. The move then promotes the dangling link, renames the original link to trash and removes the trash. The target content remains on disk. However, the skill disappears from discovery until the user repairs the link.Before this change, the plain
renamefailed withEXDEVand nothing changed on disk. The new fallback causes this regression.Fix: run
lstat(sourceDir)first. IfsourceDiris a symlink, do not copy the tree. Create a new link atdestDirwhose target is resolved againstpath.dirname(sourceDir), then remove the old link. Alternatively, reject the move withsymlink_escapes_skill. Add a test for anEXDEVmove of a direct skill that is a relative symlink.Proposed fix

Learning: In `src/services/skills/SkillsManager.ts`, a first-level symlink under a configured skills root is intentionally trusted to support skill discovery in symlinked containers. For PR #1843, pointing that symlink at a very large directory is treated as user configuration error; a directory-visit budget is not required for this change.

This is looking good - thanks for iterating on this, had 2 error handling comments.
Thanks.
Related GitHub Issue
Closes: #1842
Description
When .roo/skills (or a subdirectory within it) is a symlink to an external directory that contains skill subdirectories rather than a single skill, Roo Code fails to discover the skills inside it. Only directories that directly contain a SKILL.md are recognized, so a symlinked "container" of multiple skills is skipped.
Test Procedure
Have this directory structure:
Start Roo Code in /project.
Open the skills list / trigger skill discovery.
skill-a and skill-b are discovered and available.
