Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00042 | $0.03186 |
| Opus 5.5 | $0.00017 | $0.01274 |
| Sonnet 5.5 | $0.00008 | $0.00637 |
| Haiku 4.5 | $0.00004 | $0.00319 |
Grade A, and why
comment 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 1mo 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 — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Comment Style
One principle across all languages: comments state what IS. They never narrate what is happening, restate what the code says, or editorialize.
The deletion test: if the comment disappears, does the reader lose information they could not get from reading the code? If no, delete it.
Style guides to load
Read the relevant guide before making comment/doc decisions. These are the canonical sources; do not rely on memory of their contents.
| Language | Guide path |
|---|---|
| Root (all languages) | style/style.md |
| Python | docs/src/style/python.mdx — see ## Documentation section |
| TypeScript | style/typescript.md |
| Rust | docs/src/style/rust.mdx |
| Go (guide) | docs/src/style/go/guide.mdx |
| Go (decisions) | docs/src/style/go/decisions.mdx — see documentation section |
Read style/style.md always. Then read the language-specific guide for
the file you are editing.
Cardinal rule: write for the least experienced reader
Code and comments should be immediately understandable by both a novice and an expert. A reader should never have to leave the file to figure out what the file does or why it exists.
This is the bar: if someone opens this file cold, with no prior context about the project, can they answer these questions within 30 seconds?
- What does this module do?
- Why does it exist?
- Where does it fit in the system?
If the answer requires reading five other files, the module doc has failed.
Short sentences, plain words
MOST IMPORTANT RULE: write like a sixth grader. One idea per sentence. No subordinate clauses when two sentences will do.
Bad: "The guest kernel sends FUSE requests over virtio-fs, a virtio
device that carries FUSE operations over shared memory instead
of a network socket, and fuse-backend-rs deserializes them and
calls our FileSystem trait impl."
Good: "The guest kernel sends FUSE requests over virtio-fs. virtio-fs
uses shared memory, not network packets. fuse-backend-rs
deserializes the requests. We answer them."
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.
- 1mo ago First seen · 386 lines · 42 tokens per session scan A c9d701d7ef38
comment is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (30 stars, last pushed 3d ago), licensed MIT. It adds 42 tokens to every session and 3,186 once invoked, about $0.0002 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 2026-08-30.
