Session Info Skill
Returns the current Claude Code session UUID and registry information.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
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.tsOutput Format
The script outputs structured session information:
Current Session: c1c1c149-1abe-45f3-8572-fd77aa046232
Short ID: c1c1c149
Project: ~/.claude
Registry: ~/.claude/projects/-Users-terryli--claude/.session-chain-cache.json
Chain Length: 3 session(s)
Last Updated: 2026-01-15T21:30:00.000ZNote: TheManaged By,Metadata(Repo, Hash, Branch, Model, Cost), andRecent Sessionssections shown in earlier versions of this doc are not yet implemented inget-session-info.ts. The script currently outputs only the 6 fields above.
Registry Location
The session registry follows Claude Code's native path encoding:
~/.claude/projects/{encoded-path}/.session-chain-cache.jsonWhere 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 |
| 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) |
Post-Execution Reflection
After this skill completes, check before closing:
- Did the command succeed? — If not, fix the instruction or error table that caused the failure.
- Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
- Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.
Only update if the issue is real and reproducible — not speculative.
