crew 0.1.0

Six subagents, each pinned to the cheapest model that holds for its job.

agent	model	when
quick	haiku	mechanical, target already named
scout	sonnet	where does X live, what would this touch — read-only
coder	sonnet	implementation against a settled plan
planner	opus	single-subsystem plan, bug-fix strategy
reviewer	opus	review a diff with real logic in it
architect	fable	spans subsystems, migrations, wire contracts

The routing table is the boring part. What makes it work is the refusals: an agent handed work below its tier names the right agent and hands back instead of doing it anyway.

Measured

From BENCHMARK.md — four identical tasks run with and without routing:

• 68.3% cheaper ($1.2792 → $0.4049), every task correct in both arms, verified by executing the code rather than trusting the agents' reports.
• A typo fix cost 33× more at the default tier than routed.
• Blind dispatch picked the right agent 18/18 from the descriptions alone.

Honest caveats are in the doc: the cheap tier reported three fewer real defects on the review task, one of two hand-back probes did not fire, and on same-model work roughly half the saving is prompt discipline rather than routing.
