Problem

When enumerating skill resources (scripts/, references/, and assets/), Skill.Resources() checked e.IsDir() directly on os.DirEntry.

Because Go's DirEntry.IsDir() returns false for symlinks, any symlink pointing to a subdirectory was mistakenly treated as a resource file rather than being skipped. Furthermore, broken or dangling symlinks were not caught.

Solution

• Inspect the target via os.Stat when an entry in a resource directory is a symlink (e.Type()&os.ModeSymlink != 0).
• Exclude symlinks that resolve to directories from the resource file list.
• Skip unresolvable or dangling symlinks.
• Enforce the maxResources limit immediately after appending each resource to avoid unnecessary traversal.
• Add regression test TestSkillResources_Symlinks.

Testing

• go test -v -run TestSkillResources ./internal/skills passes.
• go test -v ./internal/skills passes.
• go test ./... passes cleanly across the entire project.

Walkthrough

Search commands and directory listings now handle symlinks in the described cases. Search fallbacks stream results and enforce limits. Extension discovery and skill resource enumeration also resolve symlink targets.

Changes: Symlink handling

Layer / File(s)	Summary
Follow symlinks and stream search results internal/core/find.go, internal/core/grep.go, internal/core/grep_test.go	The fd, find, ripgrep, and standard grep commands now follow symlinks. The find and grep fallbacks stream output and stop at configured limits. Error and partial-result handling changed. Tests cover long lines, match limits, and symlink traversal in the grep fallback.
Recognize symlinked directories internal/core/ls.go, internal/ui/dir_picker.go, internal/ui/file_suggestions.go	Core and UI directory listings resolve symlink targets and classify directory targets as directories. UI listings use bounded target checks. The core listing checks for context cancellation during iteration.
Scan and deduplicate symlinked extensions internal/extensions/discover.go, internal/extensions/loader.go	Extension discovery follows symlinked directories. Git-package filtering also checks a resolved repository path, and results are deduplicated by resolved target.
Handle symlinks in skill resources internal/skills/skills.go, internal/skills/skills_test.go	Skill resource enumeration includes symlinks to files and skips symlinks to directories or unresolved targets. A test checks these cases.

Suggested reviewers: ezynda3

Merge Risk: Moderate · up to 7ae76

Symlink support improves, but valid extensions can still disappear from discovery, incomplete searches can lose warnings, and discovery tests can fail under symlinked temporary directories. Resolve these issues before merging; large ripgrep searches and slow skill-resource targets also retain resource-use risks.

Full details: Title check

Explanation

The title "fix(skills): follow symlinks when enumerating skill resources" matches the main change in internal/skills/skills.go. The change makes Skill.Resources follow symlinks in resource directories. Symlinks to files are included, and symlinks to directories and unresolvable targets are excluded. The test file adds TestSkillResources_Symlinks to cover this behavior. The title is specific and accurate. The PR objectives also cover find, grep, ls, extensions, and UI, but the title names only the skills part. That is a narrower scope than the full PR, which is acceptable because the title does not need to cover every detail.

Full details: Docstring Coverage

Explanation

Docstring coverage is 68.75% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 16 functions across 11 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Resolve symlinked repository roots before scanning.

When a repository symlink has no include filter, walkExtensionCandidates does not traverse its target. For a repository name without a .go suffix, discovery returns no extensions. Resolve the root before traversal while preserving the expected candidate paths.
