# deep-research

This skill investigates a topic across multiple sources and saves a cited report. Use it when claims need checking, comparison, and a documented trail.

## What it does

The skill turns a research request into a set of concrete subquestions, then tracks the work with `todo_write`. It discovers material through `web_search`, reads selected pages with `fetch_url`, records source details, and checks for stale or conflicting claims. Broad topics can be split across available agent or task tools found with `tool_search`.

It writes a self-contained Markdown report to the path supplied by the slash command. The report includes a title, summary, findings, open questions, and numbered citations linked to a sources section. The environment must provide `web_search`, `fetch_url`, `todo_write`, `read_file`, and `write_file`; without the first two, the source-gathering phase cannot run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill deep-research -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/deep-research/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/deep-research/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill deep-research -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/deep-research/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill deep-research -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/deep-research/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install autohandai/code-cli deep-research
```

2. **Manually: put the files in place**
- File: `.github/skills/deep-research/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill deep-research -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/autohandai/code-cli --path src/skills/builtin/deep-research
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/deep-research/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill deep-research -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- turn a broad topic into researchable subquestions
- find and read primary sources
- check claims across independent references
- save a cited report with documented uncertainty

## Example prompts
- Research this question across primary sources and save the report to `research/report.md`.
- Compare official documentation and papers on this topic, flag contradictions, and write the result to `docs/research.md`.
- Break this request into subquestions, verify each one with multiple sources, and save the Markdown report at `reports/topic.md`.

---

You conduct iterative, multi-source deep research and produce a reusable cited research report.

## Scope The Question

1. Restate the user's research topic or question in concrete terms.
2. Identify 4-8 subquestions that would fully answer it.
3. Ask at most one clarifying question only when the topic is too ambiguous to research safely.
4. Track the research phases and subquestions with `todo_write`.

## Gather Evidence

For each subquestion:

1. Use `web_search` to discover current sources.
2. Use `fetch_url` to read the strongest sources instead of relying on snippets.
3. Prefer primary sources, official documentation, papers, standards, release notes, or direct project/company material.
4. Record each source URL, source title, publication date when available, fetched date, and confidence.
5. Look for disagreement, stale claims, and missing context.
6. Continue pulling threads until every subquestion is answered or the gap is explicitly documented.

Use `tool_search` to find available agent, task, or parallel research tools when the research topic is broad enough to benefit from delegation.

## Synthesize

1. Cross-check load-bearing facts against at least two independent sources when possible.
2. Note whether evidence is recent, historical, speculative, or contradicted.
3. Resolve contradictions when the evidence supports a resolution; otherwise flag them.
4. Keep unverified claims out of the report.

## Report

Write a self-contained markdown report to the path supplied by the slash command.

Required sections:

- `# <clear title>`
- `## Summary`
- `## Findings`
- `## Open questions / uncertainty`
- `## Sources`

Findings must be organized by theme or subquestion and include inline numbered citations like `[1]`.

The Sources section must number every cited source and include title, URL, publication date if known, and fetched date when useful.

Do not stop until the report is saved with `write_file` and the final response includes the exact saved path.
