feat(tasks): let the agent-server send its own run callbacks by charlesvien · Pull Request #116716 · PostHog/posthog

charlesvien · 2026-10-14T03:01:23Z

Problem

agent-proxy and Django's ingest each parse the agent's event stream and call Django on its behalf.
So turn results only reach the workflow through the streaming plane, with the same parsing in two places.

Changes

The agent-server sends every callback itself to a new agent_callback endpoint: heartbeats, boot milestones, finished and failed turns, budget steers and process kills.
Turn results, budget steers and process kills go only after ingest acks the event, with its sequence. Django drops retried turn results on that sequence.
If the ack takes over 30s, a turn result goes without a sequence. A budget steer or process kill is dropped.
agent-proxy and Django ingest only stream for agents that send X-PostHog-Agent-Callbacks.
Behind tasks-agent-sends-callbacks. Older agent builds and Slack relay runs are unchanged.
Nothing changes for users.

How did you test this code?

Automated tests only. No end-to-end cloud run. Repo-wide mypy not run. Not covered: a server-level test that each agent server reports once per turn.

Test rationale: The agent's callbacks and the ingest handlers' silence must switch together, so each side has a test. The sender tests pin the ack and its final sequence after a restart. The endpoint tests check that only the run's own sandbox gets through and that a retried turn result is dropped.

Docs update

Updated the agent-proxy README and docs/internal/task-run-api.md.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Agent: Claude Code, claude-opus-5-5

Skills: /improving-drf-endpoints, /writing-tests, /writing-pr-descriptions, /debugging-ci-failures.
The ack-then-report design and seq dedupe follow a discussion with the agent infrastructure owner about ordering and retries.
desktop-skip-backend-check is set because the agent and backend halves can ship in either order.

✅ Toolbar bundle — eager 2.23 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

[High impact] Agent server now sends its own task callbacks to the backend.

Fix run-bound authorization and heartbeat delivery during buffer exhaustion before merging; the required absent-result convention also needs to be satisfied.

@charlesvien Your GitHub account is linked to more than one PostHog account, so I can't tell which to run this as. Disconnect GitHub from the accounts you don't use, then comment again.
