# Deep Research Synthesizer Use this skill when you have **five sub-agent research results** and need to produce a **single high-quality Markdown report** that: - answers the user’s question directly - preserves evidence + citations - removes duplication - flags contradictions and gaps - never “silently fails” when one agent output is missing or malformed This skill is designed to fix a common anti-pattern: *a coordinator prompts 5 agents, then tries to “just synthesize” without a contract, validation, or observability*. --- ## Inputs expected (minimum) 1) `user_question` — the user’s original question (verbatim) 2) `agent_outputs[5]` — one output per agent. Each output MUST follow the **Research Packet Contract** (see `references/AGENT_PACKET_CONTRACT.md`). If you cannot guarantee the contract, run `scripts/validate_packets.py` and repair nonconforming outputs before synthesis. --- ## The 5-agent pattern that works ### Step 1 — Partition the work (pick ONE strategy) **Strategy A: Time slicing (good for “what happened” / “how it evolved”)** - Agent 1: earliest timeframe - Agent 2: next window - … - Agent 5: most recent window + “what changed recently” **Strategy B: Source slicing (good for broad topics)** - Agent 1: primary sources / official docs - Agent 2: academic papers / standards - Agent 3: practitioner writeups - Agent 4: competing viewpoints / critiques - Agent 5: synthesis + “what you should do” recommendations **Strategy C: Sub-question slicing** - Agent 1: definitions / scope - Agent 2: current state - Agent 3: failure modes / risks - Agent 4: options + tradeoffs - Agent 5: recommendations + decision framework ### Step 2 — Enforce the Research Packet Contract Every agent must output: - a machine-parseable JSON “packet header” - a short narrative - a “Run Log” with searches + errors Contract details: `references/AGENT_PACKET_CONTRACT.md`. ### Step 3 — Validate before you synthesize Run: ```bash python scripts/validate_packets.py --in packets/ ``` Fix failures immediately: - missing sources - missing claims/evidence mapping - missing run logs - malformed JSON ### Step 4 — Normalize + deduplicate Use: ```bash python scripts/merge_packets.py --in packets/ --out merged.json ``` Then synthesize using the report template: - `references/REPORT_TEMPLATE.md` - include contradictions + gaps explicitly ### Step 5 — Synthesize the final report (Markdown) Write the report in this order: 1. **Executive Summary** (5–10 bullets) 2. **Direct Answer** (2–6 paragraphs) 3. **Key Findings** (grouped, deduped) 4. **Evidence & Citations** (trace claims → sources) 5. **Contradictions / Uncertainties** (what doesn’t match) 6. **Recommendations** (actionable, prioritized) 7. **Appendix** - per-agent “Run Log” - per-agent “Raw Findings” (optional) ### Step 6 — QA checklist (do not skip) Use `references/QA_CHECKLIST.md`. If you can’t pass the checklist due to missing info, output a partial report and explicitly list: - which agents failed - what is missing - what follow-up tasks would resolve it --- ## Failure-handling requirements (what stops “constant failures”) ### 1) Never hide missing agent outputs If any agent output is missing/empty: - produce the report anyway - mark the missing agent as “NO DATA” - do not invent what it “would have found” ### 2) Surface tool errors verbatim If an agent hit a tool error (HTTP, MCP, API): - carry the raw error into the appendix - summarize the impact in “Limitations” ### 3) Preserve traceability Every major claim must have: - source id(s) - agent id
