Research

Challenge system assumptions against accumulated evidence. Triages observations and tensions, detects patterns, generates proposals. The scientific method applied to knowledge systems. Triggers on "/rethink", "review observations", "challenge assumptions", "what have I learned".

Research a topic and grow your knowledge graph. Uses Exa deep researcher, web search, or basic search to investigate topics, files results with full provenance, and chains to processing pipeline. Triggers on "/learn", "/learn [topic]", "research this", "find out about".

Use when an operation issue is a Paperclip cursor-window, distill, or backfill — `operationType: "distill"` or `"backfill"` and the body references a Paperclip source bundle for a project or root issue. Turn raw Paperclip activity into a wiki-insightful project page, decisions log, and history note. This skill exists specifically to replace the stiff, datestamp-heavy templated output that the deterministic distiller produces.

Plan and execute user research — interviews, surveys, usability tests. Use when you need primary evidence to inform a product decision.

This skill should be used when the user gives sustained time for research, spec-writing, ideation, or deep planning. Triggers on "we have X hours", "all night", "take your time", "I'm going to sleep, keep working", "don't stop early", "go deep on X", or any indication the user wants full use of a time window. Covers planning, clock discipline, tier structure, depth standards, pivot protocol, and quality bar.

TAM/SAM/SOM analysis, customer persona development, survey design, and market sizing for new products, markets, or pivots.

Structured first-pass exploration of an unfamiliar codebase — what to read, in what order, what to map, what traps to find. Use when entering any new or inherited project before writing code.

当用户明确要求“推荐投稿期刊”“帮我的论文选 SCI 杂志”“这篇 manuscript 适合投哪些 journal”“期刊匹配/选刊/投稿建议”时必须使用。适用于用户提供全文、摘要、Markdown、LaTeX、PDF、Word 或混合材料的场景；本 skill 会基于 manuscript 与用户偏好，先用内置 `2023IF.xlsx` 做最小硬过滤生成候选池，再由宿主模型自主规划 Set1/Set2/Set3，并联网核验 scope / 质量 / 近 3 个月 PubMed 论文，最后输出 1 份按推荐度排序的 Markdown 选刊报告。⚠️ 不适用：用户只是想润色论文、只想翻译摘要、或只问某个单一期刊的官网信息而不需要系统选刊。

检查 NSFC 标书正文引用与参考文献的一致性与真实性风险（只读）：核查 bibkey 是否存在、BibTeX 字段与 DOI 等格式问题，并生成结构化输入供宿主 AI 逐条评估“正文表述是否真的在引用该文献”；默认仅输出审核报告，不直接修改标书或 .bib（除非用户明确要求）。

当用户明确要求"标书QC/质量控制/润色前质检/引用真伪核查/篇幅与结构检查"时使用。对 NSFC 标书进行只读质量控制：并行多线程独立检查文风生硬、引用假引/错引风险、篇幅与章节分布、逻辑清晰度等，最终输出标准化 QC 报告；中间文件默认归档到“交付目录内的隐藏工作区（.nsfc-qc/）”，并兼容 legacy `.nsfc-qc/`。

当用户明确要求"写/改 NSFC 立项依据""立项依据写作/重构"时使用。基于最小信息表输出价值与必要性、现状不足、科学问题/假说与项目切入点，并保持模板结构不被破坏。适用于 NSFC 及各类科研基金申请书的立项依据写作场景。

去除 NSFC 标书中的 AI 机器味，使文本读起来像资深领域专家亲笔撰写（不适用：非标书内容/需修改格式/需补充新内容）
