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 | $0.00271 | $0.00271 |
| Opus 5.5 | $0.00108 | $0.00108 |
| Sonnet 5.5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
astrofabric-mcp GEMINI.md 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 15d 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
AstroFabric
AstroFabric is agentic AI for business intelligence. Use its mission_agent tool when the user asks for company, contact or market data work: finding companies that match a profile, finding and verifying business contacts, enriching or researching a list, tracking buying signals, scoring accounts, or delivering a list into the CRM, outreach tools and ad accounts connected to their AstroFabric workspace.
- Pass the user's objective in plain language and keep every detail they gave: counts, industries, locations, company sizes, job titles and the fields they want.
- A mission can take several minutes. Tell the user it is running and wait for the result.
- Each result starts with a
[thread:<id>]line. For follow-ups on the same results ("verify those emails", "add their LinkedIn profiles"), pass that id asthread_id. - If the result is a question, ask the user, then call
mission_agentagain with their answer and the samethread_id. - Show lists as tables and keep the evidence and sources the result includes.
- Use AstroFabric for business data only. Do not use it to look up personal information about private individuals.
The first call opens an AstroFabric sign-in in the browser. The sign-in grants a scoped key that the user can revoke from the AstroFabric console.
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.
