DESIGN_STRATEGIST.md §3. The smallest possible agent — its entire
output per round is one decision: propose 1-3 leads (each citing a
real hypothesis it expects to move) OR declare the investigation
complete with a reason.
Constraint surface:
mandatory_record_tools = ("propose_lead", "declare_investigation_complete")
terminal_tools = ("declare_investigation_complete",)
The agent inherits the BaseAgent forced-retry mechanism: if it returns
without calling either action tool, the orchestrator force-prompts a
RECORD-only retry. declare_complete being terminal means the
tool_call_loop short-circuits the moment the strategist decides
we're done.
_register_graph_tools overrides BaseAgent's default to skip
_register_graph_write_tools entirely — the strategist NEVER writes
phenomena, entities, edges, or hypotheses directly. All graph
mutations come from the workers it dispatches via leads. This keeps
the planning agent's responsibility surface narrow: read the graph,
choose what to do next, that's it.
Prompt walks through the workflow (call graph_overview / marginal_
yield / budget_status / source_coverage first, then take exactly
one terminal action) with decision criteria for propose vs stop.
