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 | $0.00043 | $0.00293 |
| Opus 5 | $0.00022 | $0.00147 |
| Sonnet 5 | $0.00009 | $0.00059 |
| Haiku 4.5 | $0.00004 | $0.00029 |
Grade A, and why
accessibility-contrast 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.
What it actually says
accessibility-contrast
Make sure text is actually readable - measured, not eyeballed.
Process
- List the text/background pairs: body on bg, headings, buttons, links, text over imagery, states.
- Compute WCAG contrast for each (the
contrast-guardhook checks CSS automatically):- Normal text: >= 4.5:1; large/bold (>= 24px or >= 18.66px bold): >= 3:1; UI/graphics: >= 3:1.
- Fix failures: darken text / lighten background, adjust the token, or add a scrim behind text over images. Keep the brand feel while reaching the ratio.
- Beyond contrast: don't rely on colour alone; check type size/weight legibility; check focus states.
Output
- A table: pair -> measured ratio -> pass/fail -> suggested fix. Confirm fixes still hit the target.
Guardrails
- State measured ratios, not guesses. AA is the floor for client/commercial work.
- A "fix" must actually reach the threshold - re-check after adjusting.
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.
