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

chart-labels-writer 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 12d 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.

Chart labels writer

What this skill does

Writes clear, precise axis labels, legends, annotations, and source lines for a chart — the text layer that makes a graphic publishable.

When to use this skill

  • You have a working chart but the labels are placeholder text or auto-generated
  • Your graphics desk needs final copy for a chart and you want to get it right the first time
  • You are reviewing a chart before publication and the labels are vague, misleading, or missing units
  • You need to write an accessible alt-text description of a chart for web publication

What you need to provide

Required:

  • What the chart shows (data, time period, geographic scope)
  • Chart type (bar, line, scatter, map, etc.)
  • What the axes or dimensions represent

Optional:

  • The editorial point the chart is making (helps prioritize annotations)
  • Source of the data
  • Publication context (print, web, social) — affects label length
  • Whether alt-text is needed for accessibility

How the Assistant Approaches This

  1. Writes a headline for the chart — a short sentence that states the finding, not just the topic
  2. Writes axis labels with correct units and formatting conventions
  3. Writes a legend if multiple series are present
  4. Suggests 1–2 annotations that highlight the editorial point (e.g., "2020: pandemic lockdown begins")
  5. Writes a source line and methodology note if relevant
  6. Writes alt-text if requested — a factual description of what the chart shows, for screen readers

Output format

Structured text blocks, each labeled by position on the chart:

  • Headline (chart title)
  • Subtitle (if needed — adds context the headline can't carry)
  • X-axis label
  • Y-axis label
  • Legend entries
  • Annotations (with suggested placement)
  • Source line
  • Alt-text (if requested)

All text is final copy — ready to paste into the chart tool.

Quality criteria

  • The headline states a finding, not just a topic ("Rent in Munich doubled since 2015" not "Rent prices in German cities")
  • Axis labels include units (€, %, thousands, per 100,000 population)
  • Annotations add context the reader cannot derive from the data alone
  • Source line credits the data origin, not the chart tool
  • Alt-text (if included) describes the pattern, not the visual decoration

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.
