Summary
The second seed wave adds an important layer to the first: once the harness is taken seriously, the next question is how work actually flows through it. The strongest additions here are artifact-first handoffs, small-role builder topology, two-pass context management, and the idea that useful systems are ecosystems rather than isolated agents.
Key points
- A dedicated build lane is more valuable than letting coding work pollute the main lane.
- Four sharp roles beat both one blob-agent and a seven-agent org chart.
- Artifact-first handoffs are a practical reliability primitive.
- Large context should be used for orientation, then narrowed aggressively for precision work.
- The best agents are supported by substrates, interfaces, and operator tooling.
- The knowledge-extraction framing is directionally interesting but too broad until scoped harder.
Recommendation
Near-term design emphasis should go to:
- task-card and artifact contract design
- builder-lane topology and reviewer independence
- explicit context-tier policy for research and coding tasks
- ecosystem-level design thinking, not just agent prompt tuning
Decision triggers
Escalate toward dedicated mission-control or builder-bot tooling when:
- coding work volume rises enough to create lane pollution
- multi-agent handoffs become common
- observability or review state becomes hard to track in chat alone
