Sync docs for agents PR #610: feat: readonly connections — restrict WebSocket clients from modifying agent state by agents-git-bot[bot] · Pull Request #28197 · cloudflare/cloudflare-docs

agents-git-bot · 2026-02-08T20:52:02Z

Summary

This PR syncs documentation changes from cloudflare/agents#610 which adds readonly connections and deprecates onStateUpdate in favor of onStatePersisted.

Changes

Readonly Connections Documentation Updates

Implementation change: Updated readonly-connections.mdx to reflect the new connection state attachment storage method (instead of SQL tables)
Clarified enforcement: Made it clear that readonly blocks both client-side setState() and callable methods that call this.setState() internally
Added enforcement diagram: Visual representation showing how readonly connections are blocked at different levels
Added caveats section: Documents side effects behavior, per-connection vs per-user limitations, and what readonly does/doesn't restrict
Updated note: Added clarification that onStateUpdateError also fires for validateStateChange rejections

API Deprecation

Renamed onStateUpdate → onStatePersisted: Updated all references across all documentation files
- store-and-sync-state.mdx
- agent-class.mdx
- get-current-agent.mdx
- quick-start.mdx
- add-to-existing-project.mdx
- webhooks.mdx
- chatgpt-app.mdx
- mcp-agent-api.mdx

Updated Documentation Sync

This PR has been updated with the correct implementation details for the readonly connections feature from cloudflare/agents#610.

Key Updates

1. Readonly connections implementation (readonly-connections.mdx)

✅ Fixed: Updated "How it works" section to reflect connection state wrapping (NOT SQL storage)
✅ Fixed: Clarified that enforcement blocks @callable() methods that call setState() internally
✅ Added: "What readonly does and does not restrict" comparison table
✅ Added: Caveats section about side effects in callables running before setState check
✅ Removed: Outdated SQL table storage details (implementation changed from SQL to connection attachment)

2. onStateUpdate → onStateChanged rename

✅ Renamed all server-side hook references from onStateUpdate to onStateChanged
✅ Updated across 7 documentation files
ℹ️ Client-side onStateUpdate callback remains unchanged (correct)

Changed Files

api-reference/readonly-connections.mdx - major rewrite with corrected implementation
api-reference/store-and-sync-state.mdx - renamed hook
api-reference/agents-api.mdx - renamed hook references
api-reference/client-sdk.mdx - renamed hook references
concepts/agent-class.mdx - renamed hook references
getting-started/quick-start.mdx - renamed hook references
model-context-protocol/mcp-agent-api.mdx - renamed hook references

Why the Force Push?

The branch previously had an earlier sync attempt with outdated information (SQL-based readonly implementation). The latest upstream changes use connection state wrapping instead, which is what this update reflects.

/bonk fix the build

@callable

The Prettier/Babel parser requires decorators to be attached to class declarations. Three code blocks in readonly-connections.mdx had standalone @callable() decorators on methods outside of a class body, causing the build to fail with 'Leading decorators must be attached to a class declaration'.

The fix is committed. Here's the summary:

Root cause: Three code blocks in src/content/docs/agents/api-reference/readonly-connections.mdx had @callable() decorators on standalone methods outside of a class body. The Prettier/Babel parser (used during build) requires decorators to be attached to class declarations, causing a SyntaxError: Leading decorators must be attached to a class declaration that failed the build.

Fix: Wrapped all three standalone @callable() snippets in export class MyAgent extends Agent<Env, State> { ... } class declarations:

Line ~152 - getPermissions() method (Checking status section)
Line ~503 - processOrder() with side effects before setState (Caveats section)
Line ~518 - processOrder() with setState first (Caveats section)
