## What it does

The agent triggers research whenever a spec choice depends on an unfamiliar library, API, version, or pattern. It prevents plausible-but-wrong assumptions from polluting the build. Every finding must cite a primary source: official documentation, a repository, an RFC, or a paper. If an assertion cannot be verified, it gets labeled with `?` instead of being presented as a fact.

The workflow follows four steps: scoping, gathering, distilling, and handoff. Broad topics get split into one to three precise questions. Long web pages never enter the main context. Instead, the agent compresses each finding into a single §R row with its source. When sources conflict, both are logged so the developer can decide.

Research proposes changes, but it never writes to `SPEC.md` directly. It hands distilled §R rows to the `spec` skill. Without the spec skill, those updates will not reach the specification file.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add JuliusBrussee/cavekit --skill research -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add JuliusBrussee/cavekit --skill research -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install JuliusBrussee/cavekit research
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/JuliusBrussee/cavekit --path skills/research
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add JuliusBrussee/cavekit --skill research -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/JuliusBrussee/cavekit/tree/HEAD/skills/research/SKILL.md

## When to use it
- check current best practices and RFCs before finalizing specs
- distill external findings into single-line §R records with sources
- flag unverified claims with `?` instead of hallucinating API behavior
- hand off discovered constraints to the spec skill

## Example prompts
- /ck:research check current best practices for refresh-token rotation
- /ck:research find a maintained JWT library for Node ESM
- Research Stripe webhook constraints before updating the spec

  Gather external knowledge the spec needs and distill it into §R — the durable
  research log — so build grounds in facts instead of hallucinating library
  behavior. Each finding cites a source; unsourced claims are flagged, never
  written as fact. Triggers when a spec decision hinges on a library/API/best
  practice the agent is unsure of, when the user says "research this", "what's
  the best lib for…", "check current best practice", or invokes /ck:research.
  Defers the §R write to the spec skill.

# research — external knowledge → §R

**Every finding cites a source. No source → flag it `?`, never write a guess as fact.**

"Process without library context gives you well-organized hallucinations."
Build invents a plausible-but-wrong API & §B fills with avoidable bugs.
Research is the external oracle: pull the real fact once, log it caveman, never re-derive.

## WHEN TO RESEARCH

- A §C/§I/§V decision hinges on a lib, API, version, or pattern you are unsure of.
- You are about to assume how an external dependency behaves.
- The idea touches a domain with real prior art (auth, payments, crypto, rate-limit).
- `/grill` parked a `?` that the outside world must answer.

Skip when the build touches only code you already wrote. Research scales to the unknown, ⊥ to habit.

## FOUR STEPS

### 1. SCOPE
Turn the unknown into 1-3 concrete questions. Vague "research auth" → "JWT lib
for Node ESM, maintained?" + "refresh-token rotation: current best practice?".
A scoped question gets a citable answer; a vague one gets an essay.

### 2. GATHER
Use web search / docs tools. Prefer primary sources: official docs, the repo,
the RFC, the paper. Two independent sources beat one confident blog. For a big
sweep, spawn a sub-agent so the raw pages never touch this context — it returns
only the distilled finding + source.

### 3. DISTILL
Crush each answer to one caveman line + its source. Drop the prose. The §R row
is the memory; the tab you read is not.

> R3|refresh token|rotate on use, revoke family on reuse-detect|datatracker.ietf.org/doc/html/rfc6819#section-5.2.2.3

### 4. HAND OFF
Emit the §R rows & hand to the **spec** skill to append. If a finding changes a
constraint or interface, note the §C/§I edit for spec too. Research proposes;
spec writes.

## SOURCE DISCIPLINE

- Cite a URL, repo, RFC, or paper per row. Verbatim identifiers/versions.
- Could not verify → write the row but flag `?` in the finding & say so. An
  unverified claim labeled honestly is fine; one disguised as fact is a future §B.
- Conflicting sources → log both, let the user pick. ⊥ silently average them.

## WHEN TO STOP

Done when every scoped question has a sourced §R row (or an honest `?`), and no
build decision still rests on an unchecked assumption. ⊥ research past the
questions you scoped — that is just burning the attention budget.
