Session Info Skill

Returns the current Claude Code session UUID and registry information.

When to Use This Skill

Use this skill when:

• Need to know the current session UUID for debugging
• Want to check the session chain history
• Verify the session registry is working
• Find correlation between sessions and transcripts

Implementation

Run the session info script:

bun $HOME/.claude/plugins/marketplaces/cc-skills/plugins/statusline-tools/scripts/get-session-info.ts

Output Format

The script outputs structured session information:

Short ID: c1c1c149
Project: ~/.claude

  3. c1c1c149 (2026-01-15T21:30:00.000Z)

Registry Location

The session registry follows Claude Code's native path encoding:

~/.claude/projects/{encoded-path}/.session-chain-cache.json

Where encoded-path replaces / with -:

• /Users/username/eon/cc-skills → -Users-username-eon-cc-skills

Troubleshooting

Issue	Cause	Solution
Script not found	Plugin not installed	Run claude plugin list to verify installation
JSONL ID undefined	No active session	Start Claude Code session first
Registry file not found	First session in project	Registry created automatically on first session
Chain length is 0	Fresh project	Normal for new projects, chain grows over time
Metadata missing	Older session format	Recent sessions include metadata automatically
Path encoding looks wrong	Special characters in path	Claude Code uses - to replace / in paths
Bun not found	Bun not installed	Install with brew install oven-sh/bun/bun
Permission denied	Registry file permissions	Check ~/.claude permissions (should be readable)
