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 | $0.01356 | $0.01356 |
| Opus 5 | $0.00678 | $0.00678 |
| Sonnet 5 | $0.00271 | $0.00271 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade A, and why
allocat design-system.instructions.md 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 2d 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlloCat — Design System
Single source of truth for all UI design decisions. This is a financial control interface — not a decorative UI.
Design Philosophy
- Minimalism & clarity
- Financial discipline through visual structure
- Speed of interaction
- Zero visual noise
Aesthetic Canvas System (Customizable Base)
AlloCat uses a dynamic CSS variable injection system. While the core philosophy remains minimal, users can tint their UI elements globally using a curated designer palette.
| Element | CSS Variable | Function |
|---|---|---|
| Background | --background |
Main page background (solid/tinted) |
| Cards | --card |
Background for interactive cards and components |
| Primary | --primary |
Toggles, primary action buttons (excluding destructive) |
| Borders | --border |
Must remain extremely subtle (e.g. 5% opacity overlay) to preserve the borderless aesthetic |
Curated Color Palette
The customizer supports the following aesthetic tints tailored to preserve contrast:
zinc, slate, stone, blue, emerald, rose, indigo, orange.
Color Rules
- No ad-hoc bright colors outside the customizable palette or explicit destructive actions.
- No gradients.
- No shadows (very minimal box-shadow only if absolutely necessary).
- Contrast defines hierarchy.

Scale

| Body | 14–16px | Regular (400) | Content text |
| Label | 12–13px | Medium (500) | Labels, captions |
Rules
- Use

- Avoid excessive font sizes — let spacing create hierarchy

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.

allocat design-system.instructions.md is an instructions file published in the GitHub repository BuiltByOctane/allocat (10 stars, last pushed 1mo ago), licensed MIT. It adds 1,356 tokens to every session, about $0.0068 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.
