Project-local skills in .claude/skills/ not discovered

Bug report

Observed:

• Skill file exists at with valid frontmatter
• Skill does not appear in available skills list in session
• System can read file (shows in system-reminder) but cannot invoke via Skill tool

Expected:

• Skills in project directory should be discovered at session start, like global skills

Evidence:

• Global skills in ~/.claude/skills/ ARE discovered
• Plugin skills (caveman) from plugin cache ARE discovered
• Project-local skill is NOT discovered

Repro:

1. Create .claude/skills/foo.md with valid frontmatter in project
2. Launch Claude Code in that project
3. Check available skills list — file not present
4. Copy same file to ~/.claude/skills/
5. Restart session — now appears

Impact:

• Can't ship project-specific skills with repo
• Teams can't share custom workflows in version control

Workaround:
Copy to ~/.claude/skills/ (global) or use skill content directly.

Session info:

• Created skill: 2026-06-01 10:18 AM
• Session started: 2026-06-04 (skill predates session)
• Platform: macOS (Darwin 25.5.0)
