## What it does

The command investigates repository files to answer technical questions strictly from code. It detects the language of your prompt and replies in that same language. Answers include a direct summary, an explanation of the flow, a table of key files, code snippets, and at least one Mermaid diagram whenever architecture or relationships are involved.

Before parsing the codebase, it resolves git remotes. It runs `git remote get-url origin` and inspects `git rev-parse --abbrev-ref HEAD`. If the origin is unclear, it stops to ask whether the project is local-only or has an upstream URL. It refuses to continue until this context is set.

This setup determines citation formatting. Remote repos get markdown links pointing directly to the branch and line number, while local folders receive `(file_path:line_number)`. Guessing is strictly forbidden by the prompt instructions.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

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

### Codex

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

### GitHub Copilot

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

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/ask.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/ask.md

## When to use it
- inspect unfamiliar codebase architecture through code evidence
- locate component definitions with line-level file references
- generate Mermaid flowcharts for system relationships
- verify repository behavior without guessing or hallucinations

## Example prompts
- /ask how does authentication flow work in this service?
- /ask where is the main database connection initialized?

# Deep Wiki: Repository Q&A

Answer a question about this repository grounded in actual source code.

## Source Repository Resolution (MUST DO FIRST)

Before answering, 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

## Question

$ARGUMENTS

## Process

1. **Detect language** of the question and respond in the **same language**
2. **Search** the codebase for files relevant to the question
3. **Read** those files to gather evidence
4. **Synthesize** an answer grounded entirely in actual code — never invent or guess

## Response Format

```markdown
## [Concise Answer Title]

[1-2 paragraph direct answer]

### How It Works
[Detailed explanation with inline code citations and at least 1 Mermaid diagram when the answer involves architecture, flow, or relationships]

### Key Files
| File | Purpose | Source |
|------|---------|--------|
| `src/path/file.ts` | [Role in the system] | [linked citation] |

### Code Example
<!-- Source: file_path:line_number -->
[Relevant snippet from actual source, if helpful]

### Related
- [Related concepts or files to explore]
```

## Rules

- ONLY use information from actual source files in this repository
- NEVER invent, guess, or use external knowledge
- ALWAYS cite source files inline using the resolved citation format:
  - **Remote**: `[src/path/file.ts:42](REPO_URL/blob/BRANCH/src/path/file.ts#L42)`
  - **Local**: `(src/path/file.ts:42)`
- Think step by step through complex questions
- If information is insufficient, say so explicitly and suggest which files to examine
