research-literature-radar发现、筛选并长期归档重要研究论文;当用户要求按主题寻找经典、rising star、社区精选、热点或顶会/顶刊论文时使用。采用分层发现策略,调用 research-literature-search 完成其中的关键词/数据库检索,再由本 skill 负责多渠道汇总、idea-level 价值判断、论文类型分类、跨轮次跟踪和论文库归档。
Research Literature Radar is an agent skill from huangwb8/ChineseResearchLaTeX. 发现、筛选并长期归档重要研究论文;当用户要求按主题寻找经典、rising star、社区精选、热点或顶会/顶刊论文时使用。采用分层发现策略,调用 research-literature-search 完成其中的关键词/数据库检索,再由本 skill 负责多渠道汇总、idea-level 价值判断、论文类型分类、跨轮次跟踪和论文库归档。
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts (for example `CHANGELOG.md`, `README.md` and `agents/openai.yaml`).
It sits in Research & Science, covering Literature review. The licence is MIT.
Read from SKILL.md and the folder at commit b8b4142. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 6 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
ghFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Research Literature Radar loads about 1.5k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 289 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

This skill also uses 10 other files; get the full folder from GitHub.把来自不同发现渠道的候选论文转成可持续维护的研究雷达。research-literature-search 只是本 skill 的一个检索子步骤,负责基于显式关键词的数据库召回、字段规范化、canonical 去重和 provenance;本 skill 仍负责分层发现、跨渠道汇总、价值判断、分类、跟踪与归档。
本 skill 负责:
用户提出“找值得读的论文”“建立某主题论文雷达”“按经典/热点/顶会等类型推荐论文”或类似发现与学习需求时触发。
必填:用户选题和目标数量。可选:领域/子主题、五类论文配额(classic、rising-star、community、hot、top-venue)、时间窗、作者/venue 白名单、排除项、是否下载公开 PDF、笔记深度。
运行前读取 .bensz-api/research-literature-radar/catalog.jsonl(不存在则创建),并保留用户原始请求和运行日期。
按用户请求和配置文件提供必要输入;缺失信息应明确列出并停止依赖该输入的步骤。
~/.bensz-skills/bugs/,当前任务继续;只有用户明确要求公开上报时,才使用本机 gh api 直传,不 clone 仓库。版本唯一来源为同目录 config.yaml:skill_info.version;本文件只描述稳定工作契约,不重复易变配置。
不要把论文发现简化成单一关键词检索。根据用户选题和目标数量,组合以下五类渠道;每类都可以使用联网检索、研究者脉络或社区信号,但必须记录其来源和用途:
research-literature-search 负责其中“基于关键词检索学术数据库”的小步骤;经典作者脉络、社区精选和热点信号不能假设会自动出现在该检索 bundle 中。
当分层策略需要关键词/数据库召回时,调用 research-literature-search 的 run,为其提供合法的 topic 和 5–25 条显式查询;随后调用其 validate。只接受 manifest.json 的 status 为 success 或 partial_success 的 bundle。没有需要数据库检索的渠道时,不得为了形式强行调用;但必须说明使用了哪些其它发现渠道。
将以下文件作为只读输入保存到本轮 radar run:
manifest.json
candidates_deduped.jsonl
provenance.jsonl
dedupe_map.json候选必须符合 rls.paper.v1。保留 manifest、contract version、artifact hash、canonical 候选数量和 search source path,便于追溯。若实际调用了 search 但 bundle 校验失败、没有合法查询或 search skill 不可发现,应停止该检索子步骤并报告原因;不能静默改用另一套内嵌 provider。其它分层渠道仍可独立记录为补充发现,但不得伪装成 search 结果。
社区精选、奖项、研究者整理、代码传播或新闻讨论等非标准数据库信号可以作为补充证据,但必须:
当补充信号产生新论文时,使用本 skill 的稳定身份键与 catalog 比对;相似但无法确认的记录标记 possible_duplicate,不得静默合并。
对全部 canonical 候选先建立 landscape,再对可能进入核心集者评分。每条记录包含 record_id、canonical_rank、role、cluster、relevance、evidence_depth、publication_status、identity_confidence、use_cases、reason、uncertainties 和 source_refs。标题可用于发现、聚类和 watchlist;摘要可支持相关性与作者自报判断;方法、结果和等价性强结论必须匹配全文证据。预印本状态与来源数量不能替代相关性判断。
由 AI 批量聚类并填写简短判断草稿,再运行 scripts/build_landscape.py --bundle <search-bundle> --draft <draft.jsonl> --output <literature-landscape.jsonl> --summary <landscape-summary.json> 做 manifest/hash、全量覆盖、ID 唯一、枚举、canonical 顺序与计数对账。确定性脚本不得硬编码领域关键词或替 AI 判定科学价值。
对核心候选按 0–5 分记录:conceptual_novelty、simplicity、surprise、generality、unification、new_primitive、follow_up_potential、practical_impact。证据质量单列为 confidence,不混入“有趣程度”。
为每篇核心候选记录总分、两句理由、关键证据、思想标签和不确定性;其余候选仍保留在 landscape,不能缩成落选总数。思想标签可使用:problem-reformulation、unexpected-simplicity、hidden-equivalence、assumption-revisit、new-measurement、failure-revealing、new-primitive、cross-domain-transfer。
用配额检查研究线覆盖,但不为填满配额选择低质量论文;再按总分、思想标签/年份/作者多样性形成精而少的核心集。辅助或待跟踪条目成为关键近邻时保留 Search record ID,并可新增 R 锚点和解读历史,不重新去重。
scripts/catalog.py 提供不依赖网络的 ID 生成、标题标准化、索引加载和重复判定;scripts/validate_layout.py 在交付前检查运行级文件是否错误写入 docs/papers/ 根目录。脚本不会下载或删除文件。
每轮先加载 catalog,再消费已验证的 search bundle。重复项只更新来源、版本、评分或跟进记录;只有真正新论文才创建目录。将 literature-landscape.jsonl、landscape-summary.json、discovery.md、selection.md、dedup-report.md 和运行摘要写入同一 runs/<run-id>/,并明确 canonical 数 = core + supporting + watchlist + out_of_scope。
交付前确认:每个实际使用的 search manifest 可消费、canonical hash 与数量可追溯;landscape 恰好覆盖每个 canonical record ID;五类渠道的适用性和覆盖情况有说明。一个可靠来源通常足以确认身份;只有元数据冲突、版本合并、疑似重复或决定性近邻才要求额外核对。ID、metadata、catalog、raw manifest 与内部路径一致;根目录 index.md 已包含每篇新增论文;docs/papers/ 根目录没有运行级文件。
目录 ID 使用 <first-author-full-name>-<year>-<keyword>:首位作者全名、四位年份和可识别工作/方法关键词均为 ASCII 小写并以单个连字符分隔。关键词优先使用公认简称;无稳定简称时使用标题短 slug。arXiv、DOI、OpenReview 等外部编号不能作为目录主名,必须写入 identifiers。
身份比对顺序为 DOI → arXiv/OpenReview → 其它稳定 ID → 标准化标题+首位作者+年份。预印本与正式版合并并保留版本链接;冲突时在关键词末尾追加稳定短哈希。已有笔记不覆盖,只补充缺失字段并在 history 写明变更原因。

Research Literature Radar fits situations like: tasks that involve Literature review.
Run `npx skills add huangwb8/ChineseResearchLaTeX --skill research-literature-radar -a claude-code`. Or copy the skill folder (skills/research-literature-radar in huangwb8/ChineseResearchLaTeX) into .claude/skills/research-literature-radar in your project. Claude Code loads it when a task matches its description.
Run `npx skills add huangwb8/ChineseResearchLaTeX --skill research-literature-radar -a codex`. Or copy the skill folder (skills/research-literature-radar in huangwb8/ChineseResearchLaTeX) into .agents/skills/research-literature-radar in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add huangwb8/ChineseResearchLaTeX --skill research-literature-radar -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/research-literature-radar, .gemini/skills/research-literature-radar, .github/skills/research-literature-radar and .opencode/skills/research-literature-radar in your project.
Going by SKILL.md and its folder, Research Literature Radar needs Python for the scripts in its folder and the command-line tools its instructions call (gh). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Research Literature Radar is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Research Literature Radar: Nature Paper Card (Yuan1z0825/nature-skills, 47k stars), Systematic Review Screener (Imbad0202/academic-research-skills, 51k stars), Literature Review (neflibata-feng/MyArxiv-Agent, 126 stars) and Preprint Search on bioRxiv (LigphiDonk/Oh-my--paper, 739 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
