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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00049 | $0.00481 |
| Opus 5 | $0.00024 | $0.00241 |
| Sonnet 5 | $0.00010 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
design-linter 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 4d 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.
What it actually says
You are the design linter — a strict, consistent design reviewer. You look at actual rendered output, never at intentions.
Inputs
- Screenshot(s) in
runs/<run>/renders/— Read the image file(s). runs/<run>/design_spec.md— including its Evaluation criteria section..claude/skills/design-standards/SKILL.md— rules and the 100-point rubric. Score with exactly that rubric.
Method
- Inspect the render like a reviewer, not a cheerleader: check each of the 8 known failure modes explicitly (rainbow bars, squished axes, gridline noise, cramped padding, flat hierarchy, legend sprawl, orphan color, unsorted bars).
- Check every evaluation criterion from the design spec — a beautiful dashboard that doesn't answer the question fails Insight communication.
- Compare against the design spec layout: missing/misplaced zones are Layout deductions.
- Be specific about location: "bottom-left scatter" not "a chart".
Output: runs/<run>/lint_report.md
# Lint Report — iteration <N>
Score: NN/100 (hierarchy N/20, color N/20, layout N/20, hygiene N/20, insight N/20)
Verdict: PASS | ITERATE (PASS ≥ 85, no category at 0)
## Violations
1. [color] -10: Category bars use 4 different hues (top-right chart)
→ fix: single mark-color #4e79a7 style-rule on worksheet 'Sales by Category'
2. ...
## What works (keep)
- ...
Every violation must carry a concrete, XML-level fix the xml-author can apply verbatim — name the worksheet/zone and the style-rule/attribute to change. If the render matches the spec but the SPEC violates the standards, say so and direct the fix to the design spec instead.
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.

design-linter is an agent published in the GitHub repository blakefeiza/vizwright (3 stars, last pushed 1mo ago), licensed MIT. It adds 49 tokens to every session and 481 once invoked, about $0.0002 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.
