[BUG] v2.1.1: Only half of custom skills loaded on WekaFS (potential inode overflow issue)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Claude Code v2.1.1 is only loading 6 out of 11 custom skills from ~/.claude/commands/ directory. The missing skills appear to be silently ignored during startup.

Environment

• Claude Code Version: 2.1.1
• Platform: Linux (5.15.0-76-generic)
• Filesystem: WekaFS (distributed filesystem)
• Location: ~/.claude/commands/

What Should Happen?

All 11 .md files in ~/.claude/commands/ should be loaded as custom skills.

Error Messages/Logs

Steps to Reproduce

The filesystem (WekaFS) generates extremely large inode numbers that may be causing overflow issues:

$ ls -li ~/.claude/commands/*.md
  346893892318594033 check_ci.md
13619871570242696273 comments.md
13032476072920281193 create_pr.md
16920294690488027865 list_plans.md
 8619202331492281473 persist_plan.md
10739170299355594761 read_summary.md
13961090350693351433 refresh_file.md
16905101331282984969 review_code.md
15144502430631067657 save_plan.md
 3562227808103956489 summarize.md
 5769559722763812873 update_plan.md

These inode numbers are in the quintillions (up to ~17×10^18), which could cause issues if Claude Code uses:

• 32-bit integers for inode storage (max: 4,294,967,295)
• Signed 64-bit integers (max: 9,223,372,036,854,775,807) - Several files exceed this!
• Hash functions sensitive to large numbers
• File caching/deduplication based on inode
• JavaScript Number type (max safe integer: 2^53 - 1 = 9,007,199,254,740,991)
