feat(code): surface Hooks v2 runtime feedback by johannes117 · Pull Request #5045 · langchain-ai/deepagents

Johannes du Plessis (johannes117) · 2026-07-24T16:53:46Z

Hook execution now reports progress, warnings, notices, and permission decisions consistently in the TUI and non-interactive client. Configured statusMessage values appear while handlers run, and server-owned hook output is no longer confined to logs.

A shared HookFeedback presenter keeps event ownership out of the UI layer while preserving ordered engine reduction. It deduplicates visible diagnostics, tracks concurrent handler statuses without clearing a still-running hook, emits validated terminal sequences once, and attributes hook-owned allow/deny decisions in both clients.

Re-anchored onto main after #5105 squash-merged. Call sites keep the parent WorkspaceTrust API and layer HookFeedback on top.

Review Guide

hooks/feedback.py — HookFeedback presenter (progress / notices / decisions)
hooks/engine.py — handler progress reporting
hooks/client_lifecycle.py, hooks/client.py — feedback attachment vs log-only
client/non_interactive.py, app.py, tui/widgets/status.py — UI/status sinks
Skim: HOOKS.md, tiny adapter/runtime/threat-model edits
Tests: test_feedback.py, then engine / client-lifecycle / status

Test plan

Added focused presenter, concurrent progress, statusMessage, server-notice, and permission-attribution coverage.
Targeted feedback / engine / lifecycle / trust / status suite passed on the prior stack tip; CI re-runs on this re-anchor.

Depends on #4971 Closes DCD-69 Server-owned Hooks v2 events now pause the agent over LangGraph interrupts, run on the client `HooksRuntime`, and resume with typed decisions. --- This starts the DCD-69 stack on top of the DCD-70 leaf (#4971). - Adds a versioned `hook_invocation` interrupt/resume transport around `HookInvocationRequest` / `HookInvocationResponse`. - Installs `ServerHooksMiddleware` for `PreToolUse`, `PostToolUse`, `Stop`, `SubagentStart`, and `SubagentStop`, gated by the session's configured server events so idle sessions skip the round-trip. - Creates a session-scoped client `HooksRuntime` and fulfills server interrupts from both the Textual adapter and headless runner. - Applies `deny`/`ask` as blocking tool errors for now; `ask` approval UX remains for DCD-71. ## Review Guide 1. `hooks/server_middleware.py` — middleware, gating, interrupt raise, decision apply 2. `hooks/interrupt.py` — `hook_invocation` pause/resume contract 3. `hooks/client.py` — client fulfillment + resume ledger 4. `agent.py` — middleware install (main + subagents) 5. `tui/textual_adapter.py`, `client/non_interactive.py` — interrupt fulfillment call sites 6.

Just a few nits, but I'm ready to stamp. I think the design is more inline with what we want. just check in with the comment I made re. the exception made for the noninteractive presentation layer
