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.

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 | $0.00052 | $0.02077 |
| Opus 5.5 | $0.00021 | $0.00831 |
| Sonnet 5.5 | $0.00010 | $0.00415 |
| Haiku 4.5 | $0.00005 | $0.00208 |
Grade A, and why
technical-writing 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Technical writing
Write so a tired engineer understands on the first read. Apply all four layers.
Three rules sit above the layers:
- Cut every word that does no work. If the sentence survives without a word, the word goes. "In order to" is "to". "It is important to note that" is nothing.
- Use the short, everyday word. "Use", not "utilize". "Help", not "facilitate". "Do", not "perform". A long word has to buy its length with precision.
- When a rule makes a sentence worse, fix the sentence another way or leave it alone. A sentence that follows every rule and sounds like a machine wrote it has failed.
The codebase is the word list. Write the real symbol, file, flag, or command name, not a synonym or a description of it.
Don't invent jargon. Use the words a developer would say out loud: "move", "delete", "a budget that only decreases", not "evacuate", "ratchet", or "endgame". A named pattern is fine when the doc says what it means the first time. Propose a new offender and its replacement as an addition to unslop's abstract-metaphor rule in your reply, with the diff. Don't edit that skill.
Vary the rhythm
A doc can obey every layer and still read machine-written: every sentence clipped short, no view anywhere, nothing specific.
- Mix sentence lengths on purpose. Short sentences land a point. Longer ones carry a fact with its condition or consequence.
- One thought per sentence does not mean one length per sentence. Split the sentence that carries two thoughts. Keep the long sentence that carries one.
- Have a view where the mode allows it. Explanation weighs trade-offs, so say what you make of them instead of listing pros and cons. Reference stays dry.
- Be specific over sterile. Not "schema changes can cause issues" but "a column rename fails the build".
Pick the mode first (Diátaxis)
One document, one mode. Two questions pick it: does the content inform action (doing) or understanding (thinking), and does it serve learning or work?
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.

technical-writing is a skill published in the GitHub repository chhoumann/t3-pstack (190 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 2,077 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 2026-10-13.
