## What it does

The skill executes a four-step investigation workflow: search for relevant files and patterns, read the implementation, collect context with tools, and provide an answer. It skips unnecessary preambles.

Responses follow Linear-compatible markdown standards. Detailed technical sections live inside collapsible blocks written as `+++Section Name\n...\n+++`. It also attaches file paths and exact line numbers to all code references.

Because the output format targets Linear issues, collapsible `+++` tags will look broken in standard markdown viewers.

## Requirements
- Works with: Linear

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill investigate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill investigate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill investigate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cyrusagents/cyrus investigate
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill investigate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cyrusagents/cyrus --path skills/investigate
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill investigate -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/cyrusagents/cyrus/tree/HEAD/skills/investigate/SKILL.md

## When to use it
- locate relevant functions and patterns across codebase files
- generate Linear-ready research notes with file paths and line numbers
- fold verbose implementation details into collapsible markdown blocks

## Example prompts
- Investigate how the payment webhook handler works and format the findings for Linear
- Find where user roles are verified and cite file paths with line numbers
- Research the caching layer implementation and summarize it with collapsible sections

# Investigate

Research the codebase and provide a clear, direct answer to the question.

## Approach

1. **Search** — Search the codebase for relevant files, functions, and patterns
2. **Read** — Read necessary files to understand the implementation
3. **Gather context** — Use tools as needed to collect comprehensive information
4. **Answer** — Provide a clear, direct answer using your findings

## Answer Format

- Present in Linear-compatible markdown
- Use `+++Section Name\n...\n+++` for collapsible sections with detailed information
- Include code references with file paths and line numbers
- For @mentions, use the Linear profile URL format from `<assignee>` context (e.g. `https://linear.app/<workspace>/profiles/<username>`)
- Be complete but concise — answer the question directly without unnecessary preamble
```
