App-Server Events Sync

Use this skill to keep CodexMonitor app-server integration accurate as ../Codex evolves.

Canonical Source

Start with:

• docs/app-server-events.md

Treat that file as the canonical runbook and update it when behavior changes.

Workflow

1. Confirm upstream baseline:

• Read Codex hash from ../Codex and update the hash in docs/app-server-events.md title.

2. Compare notification methods:

• Diff Codex v2 notification method set against CodexMonitor routing in src/utils/appServerEvents.ts and src/features/app/hooks/useAppServerEvents.ts.
• Update Supported Events and Missing Events sections in docs/app-server-events.md.

3. Compare request methods:

• Diff Codex v2 client/server request sets against CodexMonitor outgoing and inbound handling.
• Update Supported Requests, Missing Client Requests, and Server Requests sections.

4. Investigate schema drift when lists look unchanged:

• Inspect v2 payload structs in ../Codex/codex-rs/app-server-protocol/src/protocol/v2.rs.
• Compare parser and normalization edges in src/utils/appServerEvents.ts, src/features/app/hooks/useAppServerEvents.ts, and src/features/threads/utils/threadNormalize.ts.

5. Implement support when requested:

• Add method/type support at parsing edges first.
• Route in app event hook.
• Update thread/item reducers and rendering only if needed.
• Keep app/daemon parity and avoid duplicated logic.

6. Validate:

• Run targeted tests for touched files.
• Run npm run typecheck.
• Run npm run test for frontend behavior changes.
• Run cd src-tauri && cargo check for backend changes.

Output Expectations

When asked for an audit or update:

• Report concrete supported and missing method deltas.
• Cite exact files that need edits.
• Update docs/app-server-events.md in the same change when behavior changed.
• Call out deliberate non-support explicitly (for example deprecated methods).
