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 | $0.00037 | $0.04645 |
| Opus 5 | $0.00018 | $0.02322 |
| Sonnet 5 | $0.00007 | $0.00929 |
| Haiku 4.5 | $0.00004 | $0.00464 |
Grade A, and why
apply-mantel-styles 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 5d 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 — 437 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rules For Applying Mantel Brand Styles
When creating visual diagrams or frontend components, you can apply the following style guidelines to ensure consistency with the Mantel brand identity.
Colour Scheme
- You should aim to use the following primary colours from the Mantel brand palette.
- You may also use tints and shades of these colours as needed, but avoid introducing non-brand colours.
Palette
| Name | Hex | RGB |
|---|---|---|
| Ocean | #1E5E82 |
rgb(30, 94, 130) |
| Flamingo | #D86E89 |
rgb(216, 110, 137) |
| Deep Ocean | #002A41 |
rgb(0, 42, 65) |
| Sky Blue | #81CCEA |
rgb(129, 204, 234) |
| Cloud | #EEF9FD |
rgb(238, 249, 253) |
Extended Palette — Brand Ramps (50 lightest → 900 darkest)
Use these tokens for tints, shades, hover states, borders, and surfaces without introducing non-brand colours. Prefer the core step (bold) for each brand colour; reach for neighbouring steps when you need contrast adjustment.

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.
