The Claude Code subagent harness instructs spawned agents NOT to write
report/summary/findings/analysis .md files — the parent reads the final
text message. Verified live: analyzer-agent skipped Write entirely and
returned the report inline, so analysis-report.md never landed on disk
and the plan/interview/status phases would find nothing to read.
New contract (orchestrator-writes pattern): analyzer-agent returns the
complete report as its final message; the analyze command saves it
verbatim to the session directory before presenting the summary.
Same class exists in plan/feature-gap/optimize/scanner agent pairs —
deliberately left for their own dogfood chunks (plan is judged as-is
first per the pipeline sequence).
