Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00011 | $0.00320 |
| Opus 5 | $0.00005 | $0.00160 |
| Sonnet 5 | $0.00002 | $0.00064 |
| Haiku 4.5 | $0.00001 | $0.00032 |
Grade A, and why
list scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Worktree List
You are executing the /hydra:list command. Show all Git worktrees of the current repository.
Process
1. Check Git Repository
git rev-parse --git-dir 2>/dev/null || { echo "Error: Not a Git repository"; exit 1; }
2. List Worktrees
git worktree list
3. Format Output
Parse the output and display clearly:
Git Worktrees:
Path Branch Commit
----------------------------------------------------------------
/home/user/project main a1b2c3d
/home/user/project-worktrees/a hydra/feature-a d4e5f6g
/home/user/project-worktrees/b hydra/feature-b h7i8j9k
4. Additional Info
For each worktree optionally show:
- Lock status (if locked)
- Prunable status (if orphaned)
# Check lock status
git worktree list --porcelain | grep -A3 "worktree"
5. If No Worktrees
If only the main worktree exists:
Only the main worktree exists (main/master).
Create a new one with:
/hydra:create {name}
Output Format
Compact table with all relevant info at a glance.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 9d ago First seen · 64 lines · 11 tokens per session scan A 9fa76e08ba7c
list is a command published in the GitHub repository Marcel-Bich/marcel-bich-claude-marketplace (13 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 320 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
