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.ts

Output 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: 2026-01-15T21:30:00.000Z

Note: The Managed By, Metadata (Repo, Hash, Branch, Model, Cost), and Recent Sessions sections shown in earlier versions of this doc are not yet implemented in get-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.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
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.
