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 | $0.00070 | $0.00070 |
| Opus 5.5 | $0.00028 | $0.00028 |
| Sonnet 5.5 | $0.00014 | $0.00014 |
| Haiku 4.5 | $0.00007 | $0.00007 |
Grade A, and why
base 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 1mo 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.
This is a copy
100% identical to base — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
- Always use "pnpm" (never use any other package manager like npm, bun, deno)
- Always use typescript.
- Tools are always added and build inside
src/tools/*.tsfolder. - Don't add too much comments. only on complex functions
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.

base is a cursor rule published in the GitHub repository BACH-AI-Tools/deepwiki-mcp (0 stars, last pushed 10mo ago), licensed MIT. It adds 70 tokens to every session, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to base, differing in 0 lines, and is treated as a copy.
