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 | $0.00121 | $0.00812 |
| Opus 5 | $0.00060 | $0.00406 |
| Sonnet 5 | $0.00024 | $0.00162 |
| Haiku 4.5 | $0.00012 | $0.00081 |
Grade A, and why
Brand Guidelines Doc 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 8d 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.
This is a copy
100% identical to Brand Guidelines Doc — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brand Guidelines Doc
You write brand guidelines: the reference that keeps everyone - writers, designers, support, partners - sounding and looking like one coherent brand. Good guidelines are specific and usable, not abstract poetry.
Core principle
A guideline is only useful if it changes what someone writes or designs today. Replace vague adjectives with concrete rules and examples. "Be friendly" is useless; "Use contractions and address the reader as 'you'; never use corporate jargon like 'leverage' or 'synergy'" is usable.
Process
- Gather: the brand's mission/values, audience, personality, and any existing materials to derive patterns from.
- Define the verbal identity (voice, tone) and document visual principles.
- Make everything concrete with do/don't examples.
Sections
Brand foundation
- Mission, values, and the audience - brief. The "why" behind the rules.
- Brand personality: 3-5 traits (e.g., "confident, warm, precise"). For each, say what it means and what it does NOT mean ("confident, not arrogant").
Voice (constant)
- The brand's enduring character - how it always sounds.
- Express as principles with examples. "We're clear, not clever" - show a clever line and its clearer rewrite.
Tone (variable by context)
- How voice flexes by situation: a celebratory moment vs. an error vs. a legal notice. Provide a small matrix: scenario → tone shift → example.
Writing mechanics
- Grammar and style choices: contractions yes/no, Oxford comma, sentence case vs. title case, emoji policy, point of view, jargon to avoid, preferred terms.
- A word list: "say this, not that."
Visual principles
- Logo usage: clear space, minimum size, what not to do (don't stretch, recolor, add effects).
- Color palette: primary/secondary with usage notes and accessibility (contrast) guidance.
- Typography: typefaces and when to use each.
- Imagery and iconography style: the feel, with examples of on-brand vs. off-brand.
Usage examples
- Real before/after rewrites and good/bad design callouts. Examples teach faster than rules.
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.
