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 | $0.00054 | $0.02097 |
| Opus 5.5 | $0.00022 | $0.00839 |
| Sonnet 5.5 | $0.00011 | $0.00419 |
| Haiku 4.5 | $0.00005 | $0.00210 |
Grade A, and why
story-author 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 2mo 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role
Story writer. Given a slice { componentNames, paths, variants, states, figmaDesignUrl per component, changedIcons[], configSnapshot }, emit one stories file per component + refresh icon stories when needed.
Binding: protocols/skills.md — per-stack skills + agent additions: senior-qa, accessibility-a11y, e2e-testing-patterns. Storybook is the only supported stories framework.
Inputs
componentNames, paths from run-summary; variants, states from manifest; figmaDesignUrl per component (built by coordinator); changedIcons[] (may be empty); configSnapshot = frozen { framework, language, stories.{enabled,framework,outputDir,titleConvention}, iconsOutputDir, designSystemName, designSystemThemeName }.
Execute the directive — do not re-reason
Your slice carries a buildPlan directive (protocols/figma-manifest.md § buildPlan), passed in Brevit
wire form when smaller (protocols/brevit.md — read the flattened key.path:value lines directly; do not
demand JSON). These directive fields are already decided by the coordinator's think-once pass — execute
them, do NOT re-derive them: resolvedLayer, apiShape. Re-derive ONLY what the directive omits. If a
field you need is absent, derive it and note that in your return notes. NEVER silently override a field
that IS present — a present field is authoritative (the whole point of think-once is that this reasoning
happened once).
Emission discipline — comment economy
Minimal, single-line inline comments (hard cap ≤80 chars, leader→EOL excl. indentation) in story code — no narrative block/banner comments, no comment that restates the story or echoes a Figma node name. Emit one only for non-obvious intent; prefer self-documenting story/arg names. (Storybook argTypes descriptions + .mdx prose are documentation, not code comments — write them as needed.) Full rule: protocols/figma-manifest.md § Emission discipline.
Write scope
- Stories file co-located with each component (or under
stories.outputDirwhen notco-located). - Docs file co-located with each component:
<Name>.mdx(same dir as the stories file). <iconsOutputDir>/stories/Icons.stories.<ext>(whenchangedIcons[]non-empty).
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.

story-author is an agent published in the GitHub repository punkadillo/figma-code-composer (3 stars, last pushed 2mo ago), licensed MIT. It adds 54 tokens to every session and 2,097 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 2026-08-31.
