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 | $0.00197 | $0.02238 |
| Opus 5 | $0.00098 | $0.01119 |
| Sonnet 5 | $0.00039 | $0.00448 |
| Haiku 4.5 | $0.00020 | $0.00224 |
Grade A, and why
copywriting 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
copywriting — write it in the product's own voice
Part of super-ux — see system-map.md. After changes, run
python3 docs/brand/lint.py.
First action, every time: read the brand pack. docs/brand/voice.md,
terminology.md, and the channels.md record for the surface being written.
No pack? Stop and hand off to brand-voice. Do not improvise a voice.
Guessing it and being wrong costs more than the pause, and a product whose
copy was invented surface by surface is exactly the drift this layer exists
to remove.
The opt-out is spoken, never assumed: "no brand" / «без бренда» — or "draft it" / «черновиком» — is the operator declining this route: write directly and say the pack was skipped on request, never skip it silently.
This skill never writes to docs/brand/. A term that is missing from the
dictionary, or a number with no row in facts.md, is reported — never
invented to finish the sentence. Adding it is brand-voice's decision.

Modes
The humanization pass runs by default, in every mode that produces text. It is not a mode you enter, it is the last step of Write, Edit and Adapt, under the guards in ai-tells.md which are not optional. The reason it is a default rather than an option: a draft nobody swept carries the markers that file grades, and a reader registers them before they can name why.

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.

copywriting is a skill published in the GitHub repository ssheleg/super-ux (3 stars, last pushed today), licensed MIT. It adds 197 tokens to every session and 2,238 once invoked, about $0.0010 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 2026-08-31.
