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 | $0.00010 | $0.00417 |
| Opus 5 | $0.00005 | $0.00209 |
| Sonnet 5 | $0.00002 | $0.00083 |
| Haiku 4.5 | $0.00001 | $0.00042 |
Grade A, and why
help scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Hydra Plugin Help
You are executing the /hydra:help command. Show the user available commands and explain the Git worktree concept.
What are Git Worktrees?
Git worktrees allow having multiple branches checked out simultaneously in different directories. Each worktree has:
- Its own working directory
- Its own index (staging area)
- Its own HEAD
This means: Parallel work on different features without git stash or branch switching.
Why for Claude Agents?
When multiple agents need to work in parallel, each needs its own directory. Otherwise:
- Git conflicts during simultaneous commits
- Overwriting changes
- Chaos in staging area
With worktrees, each agent gets its own isolated working directory.
Available Commands
Show currently available commands:
grep -A2 "^ [a-z]" "${CLAUDE_PLUGIN_ROOT:-$(dirname $(dirname $0))}/plugin.yaml" 2>/dev/null || echo "Could not read plugin.yaml"
Typical Workflow
1. /hydra:create feature-x # Create worktree
2. /hydra:spawn feature-x "..." # Agent works there
3. /hydra:watch # Live monitor agents
4. /hydra:status # Check git status
5. /hydra:merge feature-x # Integrate changes
6. /hydra:cleanup # Clean up
Parallel Workflow
1. /hydra:parallel feature-a:Task A | feature-b:Task B | feature-c:Task C
2. /hydra:watch # Monitor all agents live
3. /hydra:merge feature-a # Merge when done
4. /hydra:cleanup # Remove merged worktrees

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.
- 7d ago First seen · 63 lines · 10 tokens per session scan A 295f1b5484ff
help is a command published in the GitHub repository Marcel-Bich/marcel-bich-claude-marketplace (13 stars, last pushed yesterday), licensed MIT. It adds 10 tokens to every session and 417 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.
