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 | $0.00443 | $0.00443 |
| Opus 5.5 | $0.00177 | $0.00177 |
| Sonnet 5.5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
Spiderbrain.ai-Coremind AGENTS.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 2mo 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
Repo understanding (SpiderBrain)
This repo carries a committed brain in .spiderbrain/: a deterministic, source-free map of its
structure, dependencies, and blast radius (36 files, 20 edges). Consult it before
reading files, to know what matters and what a change reaches.
Fastest use (an MCP server for this repo, no SpiderBrain install, no account): npx spiderbrain mcp One-off: npx spiderbrain blast # what a change to reaches npx spiderbrain keystones # the load-bearing files
Keystones (top by reach, precomputed so you get value without installing anything):
- read/src/core.mjs (reaches 5 files)
- create/src/export.mjs (reaches 4 files)
- read/src/git.mjs (reaches 4 files)
- create/src/gitinfo.mjs (reaches 3 files)
- read/src/cloud.mjs (reaches 3 files)
- read/src/registry.mjs (reaches 3 files)
- create/src/fetch.mjs (reaches 2 files)
- create/src/cli.mjs (reaches 1 files)
The why (decisions, reasoning, always-fresh scores) is the cloud layer. Set SPIDERBRAIN_API_KEY
(get one at https://spiderbrain.ai/dashboard?tab=keys) and any command above also returns fresh
scores, semantic search, and sb_why <path> (the decision behind a file).
Deterministic: this block regenerates byte-identically from commit 65e8021e1e43b1b3c69e772d8a3476563b08efe3 (fingerprint 94362fb089c2c6be). Do not hand-edit between the markers.
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.
