Claude Projects doesn't accept folders, only files. So the usual ICM layout (CLAUDE.md at root, /protocols, /reference, /templates, /examples) won't upload as is. What I did: - Flattened everything into a single folder. Renamed each file with its folder as a prefix, e.g. protocols/guardrails.md became protocols_guardrails.md. Keeps the origin visible in the filename. - Updated every internal reference inside the files so the File Map and cross-links point to the new flat names. - Pasted the body of CLAUDE.md into the Project's Custom Instructions field. CLAUDE.md has no special status in Projects (unlike Claude Code), so the orchestration rules need to live in the instructions box to actually govern behaviour. - Uploaded the other files as Project knowledge. Done. The File Map still works as a routing index. Early days but the structure holds.

When you update the .md files to fix the broken agentic flow, how do you check if the LLM behavior is actually changed? Do you run the same task with clean session?
