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 | $0.08773 | $0.08773 |
| Opus 5.5 | $0.03509 | $0.03509 |
| Sonnet 5.5 | $0.01755 | $0.01755 |
| Haiku 4.5 | $0.00877 | $0.00877 |
Grade A, and why
quarry 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 yesterday.
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 — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quarry
Part of Punt Labs. This repo must be checked out inside the punt-labs/ workspace meta-repo so that org-wide configuration loads via Claude Code's ancestor directory walk:
punt-labs/CLAUDE.md— org workflow, delegation model, beads issue tracking, tool configurationpunt-labs/.claude/rules/python-*.md— 19 Python OO coding rules, scoped viapaths:frontmatter (load on-demand when.pyfiles are touched)punt-labs/.envrc— git identity, beads DB connection, API keys from platform keychainpunt-kit/standards/— canonical reference docs
If cloned outside the workspace, these rules and configuration will not be present.
OO Python standards adopted 2026-05-13. The codebase does not yet fully comply. Every commit must improve OO scores (make check-oo), never regress. Do not match existing code patterns that violate the rules — write new code to the standard and improve touched files incrementally.
Local semantic search for AI agents and humans. Indexes 20+ document formats, embeds with a local ONNX model (snowflake-arctic-embed-m-v1.5, 768-dim), stores vectors in LanceDB, and serves via CLI, an MCP stdio server, and an HTTP API — all backed by the quarryd daemon (port 8420).

Mandatory Reading
Source-of-truth documents, @-imported so they stay in context. Read them
before writing code.
docs/WORKFLOW.mdis the authoritative development process: three nested loops (backlog → PR → mission), each with pseudocode for its control flow and a Z schema for its entry/exit doorway conditions. The Development Loop section below is a pointer to it, not a second copy.DESIGN.mdis the ADR log (DES-001+); on any conflict about settled architecture, it wins. Read it before proposing changes.
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.

quarry CLAUDE.md is an instructions file published in the GitHub repository punt-labs/quarry (7 stars, last pushed 2d ago), licensed MIT. It adds 8,773 tokens to every session, about $0.0351 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 2026-08-31.
