In plain words

It helps add component stories, cover every property variant and state, and use the project's shared light and dark display settings.
Why use it?
It helps reveal missing visual or behavioural cases by covering the component's property variants and states in one place.

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

add-component-story 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 11d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add Component Story

Create the Storybook story given $ARGUMENTS in the format <ComponentName>.


Gotchas

  • Never import React from 'react' in story files — jsx-runtime handles JSX and Storybook's own types cover everything else.
  • Import the component from the package (@agentic-ds/core or @agentic-ds/agents), not by relative path — this is the existing story convention.
  • Every variant needs a story before the component is considered done — enumerate the props interface; do not stop at Default.
  • Light/dark comes from the global toolbar, not from stories.storybook/preview.tsx wraps every story in AgenticProvider with the selected colorScheme. Never wrap a story in AgenticProvider yourself, never add per-scheme story duplicates, and never hardcode scheme-specific background hexes in a story.
  • No approval gate — creating/extending one story file is the whole task; proceed without asking.

Step 1 — Locate the component source

ls packages/core/src/<ComponentName>/<ComponentName>.tsx packages/agents/src/<ComponentName>/<ComponentName>.tsx 2>/dev/null

If no output, stop immediately and respond:

## No source: <ComponentName>

Neither package contains `<ComponentName>`. Create it first with
`/add-component-source <ComponentName>` (source only) or `/add-component <ComponentName>` (full scaffold).

Infer the package (core or agents) from which path exists.

Step 2 — Read context

Read:

  • .claude/skills/shared/references/conventions.md — import rules, file layout
  • The component source file — enumerate every prop, variant, enum value, and state
  • One existing story in apps/storybook/src/stories/ (e.g. ThinkingIndicator.stories.tsx) — story style
  • If apps/storybook/src/stories/<ComponentName>.stories.tsx already exists, read it — extend it, don't recreate it

Step 3 — Create or extend the story

File: apps/storybook/src/stories/<ComponentName>.stories.tsx

Changes

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.
