Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00000 | $0.00605 |
| Opus 5 | $0.00000 | $0.00302 |
| Sonnet 5 | $0.00000 | $0.00121 |
| Haiku 4.5 | $0.00000 | $0.00060 |
Grade A, and why
lobster 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 13d 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.

How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lobster
Lobster executes multi-step workflows with approval checkpoints. Use it when:
- User wants a repeatable automation (triage, monitor, sync)
- Actions need human approval before executing (send, post, delete)
- Multiple tool calls should run as one deterministic operation
When to use Lobster
| User intent | Use Lobster? |
|---|---|
| "Triage my email" | Yes — multi-step, may send replies |
| "Send a message" | No — single action, use message tool directly |
| "Check my email every morning and ask before replying" | Yes — scheduled workflow with approval |
| "What's the weather?" | No — simple query |
| "Monitor this PR and notify me of changes" | Yes — stateful, recurring |
Basic usage
Run a pipeline
{
"action": "run",
"pipeline": "gog.gmail.search --query 'newer_than:1d' --max 20 | email.triage"
}
Returns structured result:
{
"protocolVersion": 1,
"ok": true,
"status": "ok",
"output": [{ "summary": {...}, "items": [...] }],
"requiresApproval": null
}
Handle approval
If the workflow needs approval:
{
"status": "needs_approval",
"output": [],
"requiresApproval": {
"prompt": "Send 3 draft replies?",
"items": [...],
"resumeToken": "..."
}
}
Present the prompt to the user. If they approve:
{
"action": "resume",
"token": "<resumeToken>",
"approve": true
}
Example workflows
Email triage
gog.gmail.search --query 'newer_than:1d' --max 20 | email.triage
Fetches recent emails, classifies into buckets (needs_reply, needs_action, fyi).
Email triage with approval gate
gog.gmail.search --query 'newer_than:1d' | email.triage | approve --prompt 'Process these?'
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

lobster is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 605 tokens. 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 2026-08-30.
