scholar-ideaExplore broad social science ideas and convert them into formal, researchable questions.
Scholar Idea is an agent skill from joshzyj/open-scholar-skill. Explore broad social science ideas and convert them into formal, researchable questions. Use when the user has an early-stage topic, puzzle, or rough question and wants sharper research questions, candidate mechanisms, scope conditions, testable hypotheses, and feasible study directions.
Its SKILL.md is about 8.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/idea-patterns.md`).
It sits in Research & Science, covering Hypothesis generation. The repository describes itself as: Open scholar skill, a claude code plugin, for academic research.
10 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 6e5ac8e. 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.
Shell commands in SKILL.md call:
bashFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
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.
Scholar Idea loads about 8.8k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 3,865 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 noted patterns worth knowing about, such as sudo or a known installer.

It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,865 words (~8,812 tokens).

Explore broad social science ideas and convert them into formal, researchable questions. Scholar Idea is an agent skill from joshzyj/open-scholar-skill. Explore broad social science ideas and convert them into formal, researchable questions.
Scholar Idea fits situations like: the user has an early-stage topic; rough question and wants sharper research questions; candidate mechanisms; scope conditions.
Run `npx skills add joshzyj/open-scholar-skill --skill scholar-idea -a claude-code`. Or copy the skill folder (.claude/skills/scholar-idea in joshzyj/open-scholar-skill) into .claude/skills/scholar-idea in your project. Claude Code loads it when a task matches its description.
Run `npx skills add joshzyj/open-scholar-skill --skill scholar-idea -a codex`. Or copy the skill folder (.claude/skills/scholar-idea in joshzyj/open-scholar-skill) into .agents/skills/scholar-idea 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 joshzyj/open-scholar-skill --skill scholar-idea -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/scholar-idea, .gemini/skills/scholar-idea, .github/skills/scholar-idea and .opencode/skills/scholar-idea in your project.
Going by SKILL.md and its folder, Scholar Idea needs the command-line tools its instructions call (bash).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Scholar Idea has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 8.8k tokens (SKILL.md is roughly 35k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 16k tokens, read only when the agent opens those files.
