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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00075 | $0.00420 |
| Opus 5 | $0.00037 | $0.00210 |
| Sonnet 5 | $0.00015 | $0.00084 |
| Haiku 4.5 | $0.00007 | $0.00042 |
Grade A, and why
booth 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
BOOTH seller
Use the bundled booth_* tools for the user's BOOTH seller account.
Workflow
- Call the task-specific tool directly. Do not check authentication before every request.
- If BOOTH tools are not visible, search the available tools for
boothorbooth_*, then continue without asking the user which MCP servers are installed. - If a tool returns
AUTH_REQUIRED, explain that a browser sign-in will open, callbooth_login, and retry the original read. - Do not use web search for private seller data.
- Treat every data tool as read-only. Do not claim to modify BOOTH, send messages, download files, or perform fulfillment actions.
- Preserve the redactions returned by the tools and mention material masking when it affects the answer.
Tool routing
- Shop overview or recent performance:
booth_get_dashboard - Connection or signed-in shop identity:
booth_auth_status - Product lists, drafts, and public or private items:
booth_list_items - One product or item ID:
booth_get_item - Order queues, statuses, and fulfillment methods:
booth_list_orders - One order ID:
booth_get_order - Revenue, sales trends, and product performance:
booth_get_sales - Customer inquiry list:
booth_list_conversations - One conversation or its messages:
booth_get_conversation - Shop name, URL, publication state, description, or preferences:
booth_get_shop_settings
For a summary that spans multiple areas, start with the narrowest useful overview and fetch additional detail only when needed.
What ships with it
1 file 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.
