# research

Runs a five-iteration investigation of one topic in your codebase, tracing real code paths and citing a source for every claim.

## What it does

The command walks through five research iterations. The first maps the topic: components, boundaries, entry points. Iterations two through four each take a different lens — data flow and state, then integration and API contracts, then design patterns, anti-patterns and technical debt. The fifth synthesises everything and adds a section on what that mental model hides.

The invariants are strict. Every claim needs a file path plus a function or class name, and the command separates what it read from what it inferred. Untraced areas get flagged instead of guessed. Each iteration is expected to carry at least one Mermaid diagram and one structured table, plus a running knowledge map split into explored, partially explored and unexplored.

Before any research starts, the command resolves the repository context: it runs `git remote get-url origin`, asks whether this is a local-only repo or has a source URL, and gets the branch with `git rev-parse --abbrev-ref HEAD`. It will not proceed until that is settled. Your topic goes into `$ARGUMENTS`, so calling it without one gets you nowhere.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

**Manually: put the files in place**
- File: `.claude/commands/research.md` — Call it with /research. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/research.md` — Call it with /prompts:research. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/research.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/research.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/deep-wiki/commands/research.md

## When to use it
- understand an unfamiliar module without reading it end to end
- follow a call chain from entry point down to storage
- surface hidden coupling between components
- catalogue technical debt with file-level references
- separate verified facts about the code from guesses based on file names

## Example prompts
- /research how are webhooks processed and where are they persisted
- /research trace the data path from the API route to the database
- /research which patterns are used in the caching layer

# Deep Wiki: Deep Research

Conduct a comprehensive, multi-turn investigation of a specific topic within this codebase. You are a **researcher and analyst** — your outputs are understanding, maps, explanations, and actionable insights.

## Source Repository Resolution (MUST DO FIRST)

Before any research, resolve the source repository context:

1. **Check for git remote**: Run `git remote get-url origin`
2. **Ask the user**: _"Is this a local-only repository, or do you have a source repository URL?"_
   - Remote URL → store as `REPO_URL`, use linked citations: `[file:line](REPO_URL/blob/BRANCH/file#Lline)`
   - Local → use `(file_path:line_number)`
3. **Determine default branch**: Run `git rev-parse --abbrev-ref HEAD`
4. **Do NOT proceed** until resolved

## Research Topic

$ARGUMENTS

## Core Invariants (NON-NEGOTIABLE)

1. **TRACE ACTUAL CODE PATHS** — Do not guess from file names. Read the implementation. If A calls B calls C, follow it all the way.
2. **EVERY CLAIM NEEDS A SOURCE** — File path + function/class name. No exceptions.
3. **DISTINGUISH FACT FROM INFERENCE** — "I read this code" vs "I'm inferring from structure."
4. **NO HAND-WAVING** — Don't say "this likely handles..." Read the code and state what it ACTUALLY does.
5. **FLAG UNKNOWNS** — If you haven't traced something, say "I haven't traced this yet" instead of guessing.

## Process: 5-Iteration Research Cycle

You will perform 5 progressive research iterations. Each builds on all previous ones. NEVER repeat prior findings. ALWAYS provide substantive analysis.

### Iteration 1: Research Plan & Structural Survey

- State the specific topic under investigation
- Map the landscape: components, boundaries, entry points
- Identify relevant files and components to examine
- Provide initial findings with file citations
- Rate confidence: HIGH/MEDIUM/LOW for each finding
- End with "Next Steps" for iteration 2

### Iterations 2–4: Progressive Deep Dives

Each iteration takes a different analytical lens:
- **Iteration 2**: Data flow and state management — trace inputs → transformations → outputs → storage. Include `sequenceDiagram` and/or `stateDiagram-v2`.
- **Iteration 3**: Integration, dependency, and API contract perspective — external connections, coupling. Include dependency graph and integration table.
- **Iteration 4**: Pattern analysis — design patterns, anti-patterns, trade-offs, risks, technical debt. Use tables to catalogue patterns and rank risks.

For each:
- Build upon ALL previous iterations
- Focus on one specific unexplored aspect
- Provide new insights with linked citations
- **Include at least 1 Mermaid diagram per iteration** (dark-mode colors) — use the diagram type that best fits the analytical lens
- **Include at least 1 structured table per iteration** — organize findings so they're scannable at a glance
- Rate confidence for every finding
- End with remaining areas to investigate

### Iteration 5: Final Synthesis

- Synthesize ALL findings from iterations 1–4
- Provide a clear mental model: "Here's how to think about this" (2-3 sentences)
- Then: "Here's what that mental model hides" (nuances, edge cases, gotchas)
- Highlight surprising or unusual findings
- Provide actionable insights and recommendations
- List key findings as numbered items with citations and confidence ratings

### Running Knowledge Map

Maintain this throughout all iterations:

```
## Explored ✅
- [component/area]: [1-line summary] — confidence: HIGH/MED/LOW

## Partially Explored 🔶
