$ npx skills add microsoft/skills --skill wiki-qa -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install microsoft/skills wiki-qa --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/microsoft/skills.git skills-src && mkdir -p .claude/skills && cp -r skills-src/.github/plugins/deep-wiki/skills/wiki-qa .claude/skills/wiki-qa && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

What it does

Wiki QA is an agent skill from microsoft/skills, published by the product's own GitHub organization. Answers questions about a code repository using source file analysis. Use when the user asks a question about how something works, wants to understand a component, or needs help navigating the codebase.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with Azure DevOps and Git. The repository describes itself as: Skills, MCP servers, Custom Agents, Agents.md for SDKs to ground Coding Agents. The licence is MIT.

When your agent uses it

  • The user asks a question about how something works
  • Wants to understand a component
  • Needs help navigating the codebase

Example prompts

  • “Use the wiki-qa skill to answer questions about a code repository using source file analysis”
  • “/wiki-qa”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  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)?"
  3. Determine default branch: Run git rev-parse --abbrev-ref HEAD
  4. Do NOT proceed until source repo context is resolved

What it can do on your machine

Read from SKILL.md and the folder at commit 354361d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Wiki QA loads about 588 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 282 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~588

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
