Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00023 | $0.00221 |
| Opus 5 | $0.00012 | $0.00111 |
| Sonnet 5 | $0.00005 | $0.00044 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
ugrc-upgrade-arcgis-v5 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 12d 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.
What it actually says
Upgrade the packages in this project to work with the new v5 of the @arcgis/core package. Also upgrade any related packages that are needed to work with the new version.
If this project uses the @ugrc/utah-design-system package, make sure that it is upgraded to the latest version which is compatible with the new version of @arcgis/core.
Fetch and use the release notes for v5 from: #fetch https://developers.arcgis.com/javascript/latest/release-notes/
Fetch and use this guide for migrating to components from: #fetch https://developers.arcgis.com/javascript/latest/migrating-to-components/
Clean up any __esri. type references and replace them with imported types.
If you see errors in the console about failure to create map layers you may need to add alias vite configurations similar to the following file #fetch https://raw.githubusercontent.com/agrc/atlas/refs/heads/main/vite.config.ts
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.
