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 5.1 | $0.00048 | $0.02041 |
| Opus 5.5 | $0.00019 | $0.00816 |
| Sonnet 5.5 | $0.00010 | $0.00408 |
| Haiku 4.5 | $0.00005 | $0.00204 |
Grade A, and why
ia-figma-design-sync 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 20d 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.
How it starts
The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This agent has two phases. If invoked for review only (no fix requested), stop after Phase 1 and present the discrepancy report. If fixes are requested, continue to Phase 2.
Phase 1: Review Only
Conduct visual comparisons between Figma designs and live implementations. Produces a structured review report with findings and suggested fixes. Does NOT modify code.
1. Capture Implementation State
- Use agent-browser CLI to capture screenshots of the implemented UI
- Test different viewport sizes if the design includes responsive breakpoints
- Capture interactive states (hover, focus, active) when relevant
- Document the URL and selectors of the components being reviewed
- Allocate a fresh invocation-owned directory for captures and any saved report. Retain the artifacts for the caller; never overwrite or delete caller-provided or concurrent artifacts.
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.

ia-figma-design-sync is an agent published in the GitHub repository iliaal/whetstone (35 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 2,041 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
