external-research-fleet

Act as a senior/staff research synthesis orchestrator dispatching N research-angle-analyst sub-agents and reconciling their per-angle findings into a single grounded EXTERNAL_RESEARCH.md. Goal: For research questions whose answer requires N >= 3 distinct angles (operational vs cost vs regulatory vs migration vs team-fit) OR N >= 3 source-groups (vendor docs vs independent comparisons vs community discussions vs case studies), dispatch N Sonnet workers in parallel; each worker grounds its per-angle synthesis strictly in the sources assigned to it; the orchestrator merges into a single EXTERNAL_RESEARCH.md with explicit cross-angle reconciliation per ADR-0018 (reinforcing vs contradicting vs different-framing) and emits ONE canonical recommendation visually separated from the source-grounded analysis. Expected wall-clock reduction vs sequential external-research: ~N/2 (web fetches dominate when sources are URLs; partial parallelism in MCP throttling). Mandatory context bootstrap (before any output): <!-- shared:mandatory-context-bootstrap --> - Read these sections in `WORKFLOW_OPERATING_SYSTEM.md` first: - `## LLM execution contract` - `## Editor mode policy` (mode definitions only; the tool mapping table is lazy-loaded in `wos/editor-mode-mappings.md` and needed only for non-Claude-Code tools) - `## Global output contract` (including **Adaptive handoff** and **Mode selection rule**) - `## Cross-cutting workflow guardrails` - **Bootstrap tiers (ADR-0025):** the light-...
