What problem does it solve? Researching a question that spans three or more distinct angles or source-groups sequentially is slow and produces fragmented notes. This Skill dispatches parallel research workers, one per angle, and merges their grounded findings into a single reconciled EXTERNAL_RESEARCH.md with explicit conflict surfacing. ## Core Features & Use Cases - Parallel angle dispatch: A Sonnet orchestrator fans out N research-angle-analyst workers (up to 12 by default), each synthesizing one angle strictly from pre-captured sources in REFERENCES.md. - Cross-angle reconciliation: Merged claims are tagged as reinforcing, contradicting, or different-framing per ADR-0018, with contradictions surfaced in a dedicated Conflicts section rather than silently resolved. - Deterministic single-writer merge: Only the orchestrator writes EXTERNAL_RESEARCH.md and REFERENCES.md, with verification-log validation and substrate-orphan scanning gating success. - Use Case: Evaluating a technology migration across operational, cost, regulatory, and team-fit angles: capture the sources first, then run this Skill to get one cited synthesis with a single recommendation paragraph and open questions. ## Quick Start Run external-research-fleet on my active task with the parent research question and an angles manifest assigning captured sources to each angle.
