Ansible Documentation Skill

Answer Ansible questions and review Ansible code grounded in official documentation from the Ansible ecosystem. This skill is complementary to ansible-good-practices which reviews code against Red Hat CoP automation good practices. This skill focuses on official Ansible documentation — module usage, playbook syntax, inventory patterns, plugin development, deprecations, porting guides, lint rules, navigator configuration, execution environments, content creation, and molecule testing.

Dependency: ansible-know MCP server

This skill requires the ansible-know MCP server (v0.7.0+) which provides the search_docs and fetch_doc tools used for documentation discovery and retrieval.

Before proceeding, verify that the search_docs and fetch_doc MCP tools from the ansible-know server are available in the current session. If either tool is not available:

1. Report to the user: "The ansible-docs skill requires the ansible-know MCP server, which is not configured in this session."
2. Provide the install command:

   uvx ansible-know-mcp
   

3. Suggest adding it to Claude Code MCP config:

   claude mcp add ansible-know -- uvx ansible-know-mcp
   

4. Decline to proceed — this skill cannot operate without the MCP server. No standalone fallback is available.

Documentation sources

To discover the current list of available sources and their descriptions, read the docs://sources MCP resource from the ansible-know server. The table below is a quick reference (as of July 2026):

If docs://sources returns additional sources not listed above, use them — the MCP server is the authoritative source of truth.

When the user's question clearly targets a specific tool, pass the source parameter to search_docs to narrow results. For general Ansible questions, omit source to search all available sources.

How to answer questions

Step 1: Analyze the user's prompt

Parse the user's message to determine what documentation is needed.

For questions (Q&A mode):

• Extract topic keywords: "loops", "handlers", "variables", "inventory", "vault", "roles", "conditionals", "facts", "templates", "lint rules", "navigator settings", "execution environment", "molecule scenario", etc.
• Identify if the question targets a specific ecosystem tool — if so, note the source to filter on.
• Identify specific module or plugin names (FQCNs like ansible.builtin.copy, ansible.builtin.template).
• Note if asking about deprecations or porting (search for "porting" or "deprecated").

For code review (code review mode):

• Read the Ansible code first.
• Scan for directives: roles:, vars:, loop:, handlers:, when:, register:, notify:, block:, rescue:, become:, delegate_to:, etc.
• Extract module FQCNs used in tasks.
• Note with_* patterns (may need migration guidance).
• Check for deprecated syntax patterns.
• Identify 2-4 distinct topic areas from the code to search for.

Step 2: Search for relevant documentation

Call search_docs with the extracted keywords. The tool returns up to 20 results per call, each with: title, summary, topic, audience, lines, source, url.

Guidelines:

• Formulate 1-3 targeted search queries (2-4 words each) based on the extracted keywords.
• If the question targets a specific tool, pass source to narrow results.
• For core Ansible concepts, pass core_only: true to prioritize curated entries.
• Select the most relevant results by matching title and summary to the user's question.

Step 3: Fetch and read documentation

For each selected search result, call fetch_doc with its url. The tool returns: content (clean markdown), title, tokens (token count), source_url.

Context budget: Do not fetch more than 50,000 tokens total across all pages in a single invocation. Use the lines field from search results as a rough pre-fetch estimate (~10 tokens per line). After each fetch, track the cumulative tokens from the response.

When the budget is tight:

• Fetch the single most relevant page first. If it consumes less than 30,000 tokens, fetch a second page.
• Use the max_tokens parameter as a guard on individual fetches. When max_tokens is set and the page exceeds it, fetch_doc returns an error (not truncated content) — retry without max_tokens if budget allows, or skip the page.
• If fetch_doc returns any error, skip the page and note to the user that it could not be loaded.

After fetching, extract the relevant sections from the markdown content rather than using the entire page verbatim.

Response modes

Q&A mode

When the user asks a question about Ansible (triggered by $ARGUMENTS containing a question, or no code path):

1. Search and fetch the most relevant documentation (Steps 1-3 above)
2. Answer the question grounded in the fetched docs
3. Cite sources — for every claim, reference the documentation URL and section heading. Use the source_url field from fetch_doc responses (or the url field from search_docs results if the page was not fetched). Format: (source: <url>, section: "{heading}")
4. If the docs do not cover the topic, say so explicitly: "The available Ansible documentation does not cover this topic."
5. Provide code examples from the docs when they exist
6. If the question relates to a specific Ansible version, search for porting guides for version-specific changes
7. If the question spans multiple ecosystem tools, search across the relevant sources

Code review mode

When the user provides a code path or asks to review Ansible code (triggered by $ARGUMENTS containing a file/directory path):

1. Read the Ansible code to review
2. Identify which documentation topics are relevant based on the directives, modules, and patterns used in the code
3. Search for and fetch the relevant documentation (Steps 1-3 above)
4. Review the code against the official documentation:
   • Flag usage that contradicts documentation
   • Flag deprecated syntax with migration guidance from porting guides
   • Flag modules used incorrectly (wrong parameters, missing required params)
   • Suggest documented alternatives where applicable
5. Cite sources for every finding — reference the doc URL and section that supports the finding
6. Present findings grouped by file, with:
   • The issue found
   • The relevant doc excerpt or guidance
   • The suggested fix
   • Source citation

Boundaries

• This skill covers official Ansible ecosystem documentation — ansible-core, ansible-lint, ansible-navigator, ansible-builder, ansible-creator, and molecule
• For specific collection module documentation (e.g., community.general.nmcli), direct the user to use the get_module_doc MCP tool from ansible-know directly
• Do not guess or fabricate documentation content — if the docs do not address something, state that clearly
• For CoP / organizational best practices review, direct the user to the ansible-good-practices skill instead
• For general Python, YAML, or Jinja2 questions unrelated to Ansible, decline and suggest appropriate resources

Relationship to ansible-good-practices

These two skills are complementary:

Both skills can be used together for a comprehensive review.
