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 | $0.07160 | $0.07160 |
| Opus 5.5 | $0.02864 | $0.02864 |
| Sonnet 5.5 | $0.01432 | $0.01432 |
| Haiku 4.5 | $0.00716 | $0.00716 |
Grade A, and why
cranelisp CLAUDE.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 26d 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 — 340 lines — stays where its author put it; the contents beside it link to each section on GitHub.

First Steps
Before doing any work, find all CLAUDE.md files in the project:
glob **/CLAUDE.md
Before doing work in any directory, read all CLAUDE.md files in that directory and every parent directory up to the project root. Local CLAUDE.md files contain conventions and context specific to nearby files.
Project Layout
| Directory | Purpose |
|---|---|
| spec/ | Language specification — owned by spec (scribe; the user arbitrates semantics) |
| design/ | Architecture and per-crate implementation design — design/arch/ owned by arch, design/{crate}/ by design |
| src/ | Compiler binary crate — pipeline, REPL, CLI, session |
crates/ |
Bounded-context library guidance: types, frontend, typecheck, backend, primitives, intrinsics, platform, exe-bundle |
| user/ | User-facing documentation — owned by docs |
| stdlib/ | Standard library in Cranelisp — a dev surface |
| examples/ | Learning sequence — owned by training |
| exemplar/ | Showcase project (Sudoku Solver) — a dev surface |

Sketch Oracle (retired)
The prototype compiler that lived in sketch/ was deleted at the close of Sprint 87 (pre-Phase-H hygiene): language semantics are frozen, and the reimplementation's own references (design/{crate}/, audits/, spec/) long ago superseded it. If a spec ambiguity ever needs the original oracle's behaviour, recover the sketch from git history rather than treating it as a live reference. Historical mentions of the sketch throughout design/, sprints/, and audits/ are an accurate record of past consultations.
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.

cranelisp CLAUDE.md is an instructions file published in the GitHub repository alilee/cranelisp (7 stars, last pushed 27d ago), licensed MIT. It adds 7,160 tokens to every session, about $0.0286 per session on Opus 5.5. 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 2026-09-04.
