## Agent reading help and troubleshooting
How to use Prime Arch, read JSON or HTML, and handle inaccessible URLs or fetch errors:

## Start with the person's assignment
Read the complete published view catalog and access instructions as HTML:
https://www.primearch.se/agent/read/

Each listed view has a complete HTML reference and an equivalent JSON projection.
Open the HTML and read actual content. If a search/web-fetch tool fails, use an
available agent browser to open the same URL, or an approved HTTP tool for JSON.
Check the view identity, question, relations, conditions and provenance before use.
A link or search snippet alone is not evidence that the reference has been read.
If no tool succeeds, report the exact URL and tool failure, not missing knowledge.
These public references require no Prime sign-in. Do not bypass access controls.

Choose guidance for understanding a concept, selecting a view, structuring material,
reviewing a model or finding knowledge for a defined area:

- English guidance: https://www.primearch.se/agent/services/en.json
- Swedish guidance: https://www.primearch.se/agent/services/sv.json

These are editorial working instructions, not executable services or canonical
ontology definitions. The visiting agent performs the analysis using published
sources and the person's business evidence. Distinguish evidence from inference;
preserve source identities, versions, scope and conditions. Ask when evidence is
missing. No customer upload is required to use this guidance.
