From d3a82ffa877ba93f9fe2e87b7f8172be5ca8ceb0 Mon Sep 17 00:00:00 2001 From: Lee Campbell Date: Sun, 1 Mar 2026 15:01:09 +0800 Subject: [PATCH 1/3] Harden devcontainer agent infrastructure Fix data loss on failed PR creation by backing up plan state and restoring on failure. Add prompt injection boundary around issue body content. Stop the agent loop on failure instead of continuing. Wire up TIMEOUT_SECONDS to CLAUDE_TIMEOUT. Parameterise upstream base branch. Fix pick-issue resume logic when plan state is missing. Add docker build step and nuget-cache volume to fleet.sh. Update .env.example to match actual env var usage.
