Reasoner timeout defaults (2h) are shorter than a normal feature build (observed 7h27m) #176

Summary

swe-planner.plan and swe-planner.execute each run an entire build phase inside one reasoner call. AgentField enforces a wall-clock watchdog per reasoner using AsyncConfig.default_execution_timeout, which defaults to 7200 s, and SWE-AF does not override it. A healthy feature build routinely needs longer than that, so the watchdog kills builds that are still making progress.

Separately, agent_timeout_seconds defaults to 2700 s (45 min), which is shorter than observed single-agent runtimes.

Steps to Reproduce

1. Run swe-planner.build for a feature that decomposes into roughly 30–40 issues.
2. Leave the node at default config (agentfield>=0.1.130, SWE-AF main).

Expected Behavior

A build that keeps producing commits and notes completes, or fails on a real error and can be resumed.

Actual Behavior

From the control plane's workflow_executions table for one 35-issue build:

So the SDK's 2-hour default is below the normal duration of the pipeline it is wrapping, and the 45-minute per-agent cap cut healthy QA/coder calls mid-edit:

QA agent failed: gate-c: Agent call 'qa:gate-c:iter1' timed out after 2700s
Coder agent failed: gate-d iter 1: Agent call 'coder:gate-d:iter1' timed out after 2700s

Environment

• OS: macOS (Apple Silicon), 8 GB RAM
• Python: 3.13
• AI provider: claude_code runtime
• Deployment: local control plane + node
• SWE-AF: main @ da78a77, agentfield 0.1.145

A node-level AsyncConfig subclass with a 12h budget (overridable through the existing AGENTFIELD_ASYNC_MAX_EXECUTION_TIMEOUT / AGENTFIELD_ASYNC_DEFAULT_EXECUTION_TIMEOUT variables), plus a 60-minute agent_timeout_seconds, would fit the pipeline's real runtime while keeping both watchdogs as last-resort bounds.
