Claude Fable 5.2 for Brand Guidelines: Extract Rules with Page References

A long brand PDF is easy to summarize and hard to apply. A designer needs the exact logo variant, minimum space and prohibited uses for one placement, with enough source detail to resolve disagreements.
This guide uses documentation reviewed on November 12, 2026 and an illustrative exercise; it does not report a live Fable test. Use Fable on a Claude surface where it is available, then manually carry the approved material into Ciyo.
Quick answer
Ask for a rule table tied to page references, inspect the cited pages yourself, and turn only confirmed rules into a creative request. Treat extracted colors and measurements as candidates until checked against the source.
1. Define the placement before reading the document
Use a fictional bookshop’s square event graphic. The question is not everything the brand believes; it is which logo, colors and text hierarchy this placement permits. Name the deliverable and attach the approved PDF on your chosen Claude surface.
Check that the document is readable there. A missing diagram or an image-only page can make a summary look complete while omitting the most useful restriction. Keep the original PDF available for side-by-side inspection.
2. Request a traceable rule table
Ask for rule, page, exact value, exception and uncertainty. If a page says the small logo is for narrow placements, preserve that condition. Do not turn a conditional choice into a universal instruction.
For example, a fictional rule might require one symbol-width of clear space. Keep that unit in the table rather than replacing it with a guessed pixel amount. Page labels printed on the document may differ from viewer page numbers; record which reference system you use.
3. Verify and carry a short checklist to Ciyo
Open every cited page and check its number, diagram and surrounding exception. Reject a color value that was inferred from a screenshot when the PDF supplies an official value elsewhere. Ask the brand owner about contradictions.
Manually bring the confirmed logo file, palette and placement checklist to Ciyo. Use the supplied logo rather than asking an image generator to redraw it. Compare the visual draft with the checklist, then confirm the saved export retains the required space.
Copy and adapt this request
Replace the bracketed fields with your own approved information. The requested output is a draft for review; the example has not been run as a model benchmark.
For [DELIVERABLE], extract applicable rules from this brand PDF. Return rule, source page, value, exception and uncertainty. Distinguish quotations from your interpretation. Do not infer absent measurements or color codes. Flag unreadable diagrams and conflicting revisions. Finish with a short checklist containing only source-supported rules.Illustrative rule register
These example checks describe acceptance criteria, not observed model results.
| Rule | Evidence required | Decision |
|---|---|---|
| Logo variant | Named source file and cited page | Use supplied file |
| Clear space | Diagram and original unit | Measure on the layout |
| Color | Official numeric value | Check source, not preview |
| Exception | Surrounding paragraph | Retain the condition |
Common mistakes and how to recover
A confident page citation can still be wrong. Check the cited page rather than accepting the reference because it looks specific.
Do not replace an unreadable logo diagram with a model’s guess. Supply a clearer page image or request the original brand asset.
Choose a working method and make the handoff
For a solo shop, start with one item and keep the source facts beside the draft. A team should name one approver and keep a dated version so an old comment cannot silently override the current decision. If the input is incomplete, return to the owner of that fact before polishing the artwork.
Use Ciyo for the visual work described here with the controls and models currently offered in your account. Keep the approved copy separately and add exact wording with editable canvas text where needed. A generated picture is a visual draft; inspect its exported file before using it.

Frequently asked questions
Does every Claude surface read PDFs identically?
No. Confirm file support and limits on the surface you use; this guide does not assume identical app and API behavior.
Can I sample colors from the PDF preview?
A preview can help inspect appearance, but use the brand’s supplied numeric values and production files for exact specifications.
Is this a brand compliance test?
It is a review method. The brand owner still decides how disputed rules apply to the actual deliverable.
