Summary

• add browser-bridged agent tools for listing, reading, writing, patching, and inspecting runtime script/style assets
• route code asset execution through existing site.files and site.runtime storage, with hash-guarded patching and runtime applicability inspection
• update agent prompt/docs to steer behavior work away from stripped <script>/onclick HTML and into write_code_asset
• keep browser-backed code asset reads classified as non-mutating and split runners to stay under module-size budgets

Verification

• bun run build
• bun test
• bun run lint
