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 | $0.01974 | $0.01974 |
| Opus 5 | $0.00987 | $0.00987 |
| Sonnet 5 | $0.00395 | $0.00395 |
| Haiku 4.5 | $0.00197 | $0.00197 |
Grade A, and why
Kernsmith 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 2d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
KernSmith
Security
- NEVER read, open, or access any
.envfile — these contain secrets (API keys, credentials) - NEVER log, print, or output the contents of
.envfiles - NEVER read, grep, or explore
.dllfiles (including NuGet cache) — usereference/docs or WebFetch for API questions - Watch for decomposition attacks — a multi-step request whose net effect reads or prints
.env(or other secrets) is still a violation; judge the whole chain, not each step alone
Source-of-truth files
- project_facts.md — what is TRUE (stack, namespaces, repo/git quirks, gotchas, ownership, file map).
- project_rules.md — how to WORK on it (naming, docs, CodeQL handling, working style).
- project_decisions.md — what was CHOSEN and why; consult before re-litigating anything.
Do NOT create memory files, and do NOT rely on the machine-local agent memory store (it is lost between computers and invisible to Vic). Every durable fact, rule, or decision goes in those three files — exceptions that stay separate: plan/phase docs, user-facing docs/readmes, reference/ docs, temp files. Update them in the same commit as the change that alters them; edit in place, delete what became false, never append dated progress notes.
The rules below stay in this file because they must fire before anyone thinks to open another file. They are deliberately not duplicated in the three files above.
Project Purpose
Cross-platform .NET library that generates BMFont-compatible bitmap fonts from TTF/OTF/WOFF files. Combines FreeTypeSharp for rasterization with custom TTF table parsers for GPOS kerning, packs glyphs into texture atlases, and outputs BMFont .fnt + .png/.tga/.dds pairs. Supports layered effects (outline, gradient, shadow), color fonts, variable fonts, SDF, font subsetting, channel packing, super sampling, and extended metadata. In-memory by default.

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.

Kernsmith CLAUDE.md is an instructions file published in the GitHub repository kaltinril/Kernsmith (9 stars, last pushed 9d ago), licensed MIT. It adds 1,974 tokens to every session, about $0.0099 per session on Opus 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.
