Troubleshoot Config

Diagnose Storybook configuration problems that block Chromatic or local Storybook and identify the narrowest fix.

Required workflow

1. Start with the current evidence: exact error text, .storybook/main.*, .storybook/preview.*, Storybook scripts and dependencies in package.json, framework or builder, one representative story path, and whether local Storybook already fails.
2. Choose one primary diagnosis from reference/diagnosis-taxonomy.md. Use reference/workflow-playbook.md when the branch is unclear. Prioritize local Storybook failures before Chromatic follow-on symptoms, framework or builder mismatches before addon speculation, and story discovery issues before version cleanup.
3. Separate local Storybook failure from Chromatic follow-through. If Storybook fails locally, fix that surface first. If Storybook runs locally but Chromatic cannot verify it, inspect build scripts, output expectations, and config shape next.
4. Inspect the repo before asking for more evidence. Use reference/command-catalog.md to check .storybook/main.*, .storybook/preview.*, the Storybook section of package.json, and one representative story path. Do not invent scripts or migration paths.
5. If one artifact is still missing, request exactly one next item using reference/evidence-ladder.md.
6. Return the diagnosis card from reference/output-contract.md. If confidence is low, name the most likely diagnosis, explain the gap, and ask for the single artifact that resolves it.

Boundaries

• Ask for one artifact at a time.
• Prefer the narrowest config repair over broad rewrites.
• Do not assume React, Vite, Webpack, or a Storybook major version without evidence.
• Do not invent script names or mix Vite and Webpack guidance unless the evidence proves a migration boundary.
