# Ansible Docs

> Answer Ansible questions and review Ansible code using official documentation from the Ansible ecosystem. Covers ansible-core, ansible-lint, ansible-navigator, ansible-builder, ansible-creator, and molecule. Use when the user asks about Ansible concepts, syntax, best practices, deprecations, or wants Ansible code reviewed against official docs. Use when user says "check my playbook against docs", "what does Ansible say about X", "how do I use module Y", or "review my role". Do NOT use for CoP good practices review (use ansible-good-practices instead). Do NOT use for general Python or YAML questions unrelated to Ansible.

# 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):

| Source | Covers |
|--------|--------|
| `ansible-core` | Playbook guides, inventory, vault, developer guides, reference appendices, porting guides |
| `ansible-lint` | Lint rules, configuration, profiles, usage |
| `ansible-navigator` | Settings, subcommands, installation |
| `ansible-builder` | EE definitions, scenarios, usage |
| `ansible-creator` | Content creation, EE scaffolding |
| `molecule` | Test scenarios, configuration, getting started |

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:

| Aspect | ansible-docs | ansible-good-practices |
|--------|-------------|----------------------|
| Source | Official Ansible ecosystem docs (6 tools) | Red Hat CoP rules |
| Focus | Correctness, syntax, features, tool config | Best practices, conventions |
| Scope | Module usage, playbooks, deprecations, lint rules, navigator, builder, creator, molecule | Naming, idempotency, architecture |
| When to use | "How do I...", "What does X do", "Is this syntax right", "How do I configure ansible-lint" | "Review my code", "Check best practices" |

Both skills can be used together for a comprehensive review.
