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.

Security

Grade A, and why

p6-a11y-visual 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 today.

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.

/p6-a11y-visual – Contrast, Colours & Dark Mode

Checks colour contrast (WCAG AA), colour-independence of information presentation, and dark mode conformance.

Argument: $ARGUMENTS = [page/component]

If provided: Check the specified page/component. If not provided: Check all critical screens.

Prerequisites

  • UI implemented
  • ACCESSIBILITY.md with WCAG target present

Agent

  • Type: ux-designer
  • Model: sonnet

Context (Orchestrator prepares)

Orchestrator reads in advance and delivers inline:

  • From src/: CSS/styles (colour definitions, dark mode variables)
  • From ACCESSIBILITY.md: WCAG target and colour requirements
  • From UX_CONCEPT.md: Colour palette, dark mode concept

Prompt Template

Goal: Check visual accessibility for: [page/component]

Styles/Colours: [inline from CSS]

WCAG Requirements: [inline from ACCESSIBILITY.md]

Output Format: Contrast table:

# Element Foreground Background Ratio WCAG Status

Colour independence:

# Element Colour-only info? Alternative present? Status

Dark mode checks:

# Element Light OK? Dark OK? Finding

Constraints:

  • Visual check ONLY – no keyboard, no screen reader
  • WCAG 2.1 AA: text >= 4.5:1, large text >= 3:1, UI elements >= 3:1
  • Account for red-green colour blindness (blue/orange instead of red/green)

Orchestrator Checkpoint

  • All colour combinations checked (light + dark)?
  • Red-green colour blindness accounted for?
  • Contrast ratios correctly calculated?

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.
