Workers retry with linear backoff (attempt*2s). Each retry uses a
unique session name suffix (-r2, -r3, ...) to avoid collisions.
Default: 1 (no retry).
- Results gathered as JSON array [{id, status, output}]
- Default output is pretty-printed JSON (no synthesis)
- -max-workers N (default 8) throttles concurrent workers
- Synthesis renders JSON to text for planner prompt
- Validate all entries have non-empty string id and instruction
- No synthesis: exit 1 on worker failures (partial results)
- Synthesis: exit 0 — planner accounts for failures in its answer
tools/cascade: fire-and-forget delegation to cheap model; worker
reports back to parent prompt when done. Parallelizable.
scripts/u/cascade: script-driven hub-and-spoke orchestrator for
terminal use — planner decomposes, workers execute in parallel,
planner synthesizes.
