Produce a rigorous, verified, fully-cited research report on ANY topic by running a disciplined five-stage pipeline: CLARIFY the question, PLAN (an editable research plan), FAN-OUT parallel search subagents, VERIFY every key claim (cross-source + adversarial + cross-model), then SYNTHESIZE a cited report. Use this WHENEVER the user wants real research rather than a quick answer — "research X", "do a deep dive on Y", "write me a report / brief / literature review on Z", "compare A vs B and back it with sources", "what's the state of the art in …", "investigate …", "find evidence for/against …", "give me a market/landscape/competitor analysis", or any question where being wrong is costly and the answer needs citations. Trigger even when the user does not say the word "research" but clearly needs multi-source, fact-checked, cited output. This is the general-topic web-research orchestrator — not the codebase-to-wiki `deep-research` skill. For a fast single-fact lookup, answer directly instead.

A Claude Code agent skill that produces rigorous, verified, fully-cited research reports on any topic by running a disciplined five-stage pipeline:
CLARIFY → PLAN (editable) → FAN-OUT (parallel subagents)
→ VERIFY (source-grounded · adversarial · cross-model)
→ SYNTHESIZE (cited report) [checkpoint/resume throughout]Every serious research system (Anthropic's multi-agent Research, Google Deep Research, OpenAI Deep Research, GPT Researcher) is the same loop. This skill makes that loop explicit and adds a layered verification discipline so the product is a report you can defend, not a fast guess.
| File | Purpose |
|---|---|
SKILL.md | The five-stage loop, the claim-ledger backbone, effort tiers, stop conditions, anti-patterns |
references/playbook.md | Per-stage procedure, subagent brief, shared research brief, ledger format |
references/verification.md | Source-grounded → adversarial → cross-model protocol (honest about what cross-model buys) |
references/evidence-standards.md | Per-domain evidence ladders, high-stakes handling, known limitations |
references/report-template.md | The cited-report structure |
scripts/checkpoint.py | Self-describing resume state (state.json) |
scripts/verify_citations.py | Mechanical report ↔ ledger consistency gate (anti "citation theater") |
claim → quoted passage → URL → date → status). The report is generated from the ledger, and verify_citations.py checks they stay consistent.Copy the research-pipeline/ directory into ~/.claude/skills/, or install the packaged .skill file.
Designed and hardened with cross-vendor review (codex + agy) on both the design and actual output reports.
