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 | $0.01885 | $0.01885 |
| Opus 5 | $0.00942 | $0.00942 |
| Sonnet 5 | $0.00377 | $0.00377 |
| Haiku 4.5 | $0.00188 | $0.00188 |
Grade A, and why
forge-skills 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 6d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
This repo ships two skills, not an application. The primary deliverable is forge — an agent-runtime-agnostic skill that turns an issue/ticket/PR reference into a shipped fix through a gated 12-step workflow. Alongside it, blacksmith-orchestrate is forge's orchestration wrapper: it takes several issues, a milestone, or a written plan, decides which of them collide and which can run in parallel, then dispatches one ordinary forge run per task. "The code" is the prose in each skill's markdown; the only executable is the installer.
Because the artifact is instructions an agent reads and follows, edits to skills/** are changes to behavior. Treat wording with the same care as code: a sentence in SKILL.md is a contract the running agent will obey literally.
Commands
Everything lives in POSIX sh; there is no package manager, build step, or linter config.
sh tests/install_test.sh # run the installer unit suite
sh tests/docs_test.sh # run the structural-invariants suite across both skills' prose
sh tests/install_test.sh | grep FAIL # quick check for failures; exits non-zero if FAILS>0
sh install.sh -h # see installer usage
tests/install_test.shsourcesinstall.shwithINSTALL_SH_SOURCED=1, which is the guard that preventsmain()from running on source (see the bottom ofinstall.sh). This lets the suite unit-test individual functions (parse_args,build_skill_group_cmd,run_installs, …) by stubbingnpx/claude.tests/docs_test.shasserts structural invariants across the shipped prose for both skills: relative markdown links resolve, the flag tables agree acrossSKILL.md/references/flags.md/README.md, noTBD/TODO/FIXMEplaceholders remain, and everyreferences/modes/*.md(forge) orreferences/*.md(blacksmith-orchestrate) file carries a manual verification recipe.- There is no single-test selector; each suite is one script. To isolate a check, comment out the others or add a temporary

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.

forge-skills CLAUDE.md is an instructions file published in the GitHub repository radimsem/forge-skills (15 stars, last pushed 13d ago), licensed MIT. It adds 1,885 tokens to every session, about $0.0094 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 2026-08-30.
