Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is BuiltByOctane/allocat's own configuration. It tells GitHub Copilot how to work on allocat itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything allocat configures →

Token cost

What it costs to keep this loaded

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.

Fable 5.1 $0.01356 $0.01356

Security

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 2mo 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.

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.

Typography

Font

Primary: Inter (Google Fonts)

Scale

Display 24–28px Bold (700) Key financial numbers
Heading 18–20px SemiBold (600) Section titles
Body 14–16px Regular (400) Content text
Label 12–13px Medium (500) Labels, captions

Rules

  • Use font-variant-numeric: tabular-nums for all financial values
  • Important numbers must always be bold
  • 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.
