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

theme 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 1mo 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.

SVG Theme Management

Themes define the colour palette for all SVG infographics. Every project needs approved theme before deliverables.

Task Tracking

MANDATORY: TaskCreate/TaskUpdate when generating themes. Tasks for swatch generation, user approval, documentation.

Theme Approval Workflow

  1. Ask user for brand colours, mood, reference materials
  2. Generate theme_swatch.svg showing all colours in context:
    • Primary, secondary, tertiary text colours with sample text
    • Accent colours with sample strokes and fills
    • Card background fills at intended opacity
    • Icon stroke colour samples
    • Mini timeline or flowchart demonstrating palette
  3. Present to user for approval before any deliverable SVGs
  4. Document approved palette in project CLAUDE.md or theme.md

When to Skip

  • Modifying existing SVGs with established palette
  • User provided and confirmed hex codes
  • Single quick SVG with clear direction

Theme Structure

Numbered shade grades in four roles:

Role Grade Purpose
fg-1 Most contrastive Headings, primary labels, hero stats
fg-2 High contrast Card titles, phase subtitles
fg-3 Medium contrast Descriptions, sublabels
fg-4 Least contrastive Metadata, tertiary text
accent-1 Primary Strokes, icons, borders
accent-2 Secondary Lighter strokes, later-phase
bg-1 Card fill Accent-1 at fill-opacity 0.04-0.06
bg-2 Track fill Accent-1 at opacity 0.3

fg-4 MUST remain readable at 9-10px.

Theme Definition Format

fg-1:       #103d82   (darkest - headings, primary labels)
fg-2:       #2a5f9e   (mid - card titles, stat numbers)
fg-3:       #4a7ba7   (medium - descriptions, sublabels)
fg-4:       #6b8db5   (lightest - metadata, tertiary text)
accent-1:   #00a6ff   (primary strokes, icons, borders)
accent-2:   #66ccff   (secondary strokes, later-phase)
bg-1:       #00a6ff at fill-opacity 0.04-0.06
bg-2:       #00a6ff at opacity 0.3

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.
