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 | $0.03852 | $0.03852 |
| Opus 5.5 | $0.01541 | $0.01541 |
| Sonnet 5.5 | $0.00770 | $0.00770 |
| Haiku 4.5 | $0.00385 | $0.00385 |
Grade A, and why
grounded-forge 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 23d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
grounded-forge, system instructions
You are working on the grounded-forge repo. The distributions this repo compiles ship their own CLAUDE.md, sourced from per-corpus build profiles under corpus.commons/{corpus}/build-profiles/ or corpus.local/{corpus}/build-profiles/.
What this repo is
A working example of the reference × task matrix architecture: a retrieval pattern that pre-projects sources to task domains at ingestion time so runtime is lookup, not reshape. Task-axis projection moves from generation time to ingestion time, produced by an LLM operating under a structured protocol that enforces source-only citation discipline.
Lenses are per-distillation modifiers applied where they materially reweight what's salient, not a third axis. Specs live at corpus.commons/{corpus}/lenses/ and are designed via the creating-lenses skill at .claude/skills/creating-lenses/SKILL.md; per-distillation applicability is decided at Pass G of creating-distillations. Each lens carries a visibility: frontmatter field (open, open-nc, copyrighted, confidential, or personal) parallel to references' Scope:; the build's max_visibility: ceiling per profile filters which lenses ship.
For the architectural argument, read in this order:
docs/reference/vocabulary.md: the noun/verb grammar. Read first; the rest assumes it.docs/architecture/overview.mddocs/architecture/llm-epistemology.md: why the matrix exists. The Larman's-Law-4 / LLM-epistemology problem the architecture is solving against.docs/architecture/projection-time.mddocs/architecture/two-layer-indexes.mddocs/architecture/matrix-pattern.mddocs/architecture/source-integrity.mddocs/architecture/known-architectural-limits.md: three limits intrinsic to the design.docs/architecture/capability-binding.md
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.

grounded-forge CLAUDE.md is an instructions file published in the GitHub repository chrisgagne/grounded-forge (8 stars, last pushed yesterday), licensed MIT. It adds 3,852 tokens to every session, about $0.0154 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.
