Wiki Q&A

Answer repository questions grounded entirely in source code evidence.

When to Activate

• User asks a question about the codebase
• User wants to understand a specific file, function, or component
• User asks "how does X work" or "where is Y defined"

Source Repository Resolution (MUST DO FIRST)

Before answering any question, you MUST determine the source repository context:

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

Procedure

1. Resolve source repo context (see above)
2. Detect the language of the question; respond in the same language
3. Search the codebase for relevant files
4. Read those files to gather evidence
5. Synthesize an answer with inline linked citations

Response Format

• Use ## headings, code blocks with language tags, tables, bullet lists
• Cite sources inline using resolved format:
  • Remote: [src/path/file.ts:42](REPO_URL/blob/BRANCH/src/path/file.ts#L42)
  • Local: (src/path/file.ts:42)
• Include a "Key Files" table mapping files to their roles (with linked citations in the "File" column)
• Include at least 1 Mermaid diagram when the answer involves architecture, data flow, or relationships — a diagram makes the answer 10x more useful
• Use tables for any structured data in the answer (component lists, API endpoints, config options, comparisons)
• If information is insufficient, say so and suggest files to examine

Rules

• ONLY use information from actual source files
• NEVER invent, guess, or use external knowledge
• Think step by step before answering
