# Deep Research V8.1 This skill is for **evidence-rich research outputs**, not for every question that happens to mention “analysis”. The V8 shift is simple: - **Single-agent first.** Start with one lead agent and only fan out when parallel work will clearly help. - **Thin harness, fat skill.** Put reusable judgment and workflow here; keep deterministic checks in scripts. - **Context organization over prompt stuffing.** Load the minimum active context bundle, then pull in references only when needed. - **Eval and observability built in.** A good report is not enough; the run must also be diagnosable and improvable. ## What this skill should produce Choose the lightest artifact that satisfies the task. | Output type | Use when | Typical length | Required artifacts | |---|---|---:|---| | **Brief memo** | user wants a concise answer with evidence | 800-1800 words | `research-plan.md`, `registry.md`, `draft.md`, `run-summary.json` | | **Full report** | user asks for comprehensive analysis / literature review / decision document | 2500-6000 words | all core artifacts + `evaluation.md` | | **Delta update** | user says “continue”, “second round”, “what changed”, “deepen round 2” | 600-1800 words | prior round handoff (`references/handoff-format.md`) + new notes + delta draft | If the user did **not** ask for a long report, default to **Brief memo**. ## When NOT to use this skill Do **not** activate for: - quick fact lookups or simple definitions - summarizing a single provid...
