story-author

story-author is an agent for Claude Code from punkadillo/figma-code-composer. It costs 54 tokens per session (2,097 once invoked), scanned A, original, MIT.

A Storybook story generator for UI components, with interaction, accessibility, and visual regression tests. Storybook is a tool for displaying and checking components in isolation.

In plain words
What is it for?
Use it after building components to create one Storybook story per component, cover its variants and states, and refresh stories for changed icons.
Why use it?
It removes the need to write and maintain these component examples and checks manually after components or icons change.

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

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 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.

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.outputDir when not co-located).
  • Docs file co-located with each component: <Name>.mdx (same dir as the stories file).
  • <iconsOutputDir>/stories/Icons.stories.<ext> (when changedIcons[] 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.
