fix(sisyphus-orchestrator): preserve subagent response in output transformation

[chilipvlmer]

Problem

When sisyphus_task completes in boulder/orchestrator mode, the tool.execute.after hook replaces the entire subagent response with git diff stats. This causes issues when:

1. Resuming a subagent that failed to complete its task
2. Debugging why a subagent couldn't fix something
3. Understanding what the subagent actually reported

The orchestrator sees identical output each time (just git stats), making it appear the subagent is "stuck in a loop" when in reality the response is being discarded.

Solution

Preserve the original subagent response by storing it before transformation and including it in the output:

const originalResponse = output.output

output.output = `
## SUBAGENT WORK COMPLETED

${fileChanges}

---

**Subagent Response:**

${originalResponse}

<system-reminder>...</system-reminder>`

Testing

• Manual verification: Resumed subagent tasks now show their actual response
• No breaking changes to existing behavior

Summary by cubic

Preserves the original subagent response in Sisyphus orchestrator output instead of replacing it with git diff stats. This fixes confusing “loop” outputs and improves debugging and resume flows.

• Bug Fixes
  • Store the subagent's original output and include it below file change stats.
  • Prevent loss of subagent details when tasks complete, aiding failed task resume and troubleshooting.

LGTM! Clean fix for an important usability issue.

What this fixes: Previously, the orchestrator was discarding the actual subagent response and replacing it with just git diff stats. This made debugging failed/incomplete tasks nearly impossible since the orchestrator only saw file changes, not what the subagent reported.

The fix: Captures the original response before transformation and includes it in the output. Simple, focused, no side effects.

Approved.
