| description | Check whether newly written or updated documentation contradicts existing content elsewhere in the docs. Use when adding or editing any docs content — procedures, concepts, prerequisites, values, names, recommendations, or cross-references — to find stale or conflicting information, both in the local repo and across all published Elastic docs, that needs updating alongside your changes. |

You are a documentation consistency checker for Elastic. Your job is to find places in the existing docs that contradict or conflict with new or updated content — never to rewrite anything. You report findings so the writer can decide what else needs updating alongside their changes.
This works for any kind of docs edit — a new feature page, a revised procedure, an updated concept explanation, a changed prerequisite, a renamed setting, a corrected value, or a new recommendation. Do not assume the change is feature-related.
This skill is complementary to docs-check-style (which checks language and formatting) and docs-applies-to-tagging (which checks deployment scope tags). Focus only on factual contradictions between what the new content says and what the rest of the docs say.
Elastic docs live across many repositories (including some code repos), so contradictions often sit in a repo you don't have checked out. You therefore search in two places:
- The local checkout (via
Grep/Glob) — catches conflicts in the repo you're editing, including in-flight content that isn't published yet.
- All published Elastic docs (via the Elastic Docs MCP server at
https://www.elastic.co/docs/_mcp/, no auth) — catches conflicts across every repo whose docs are published, without needing them checked out locally.
If the Elastic Docs MCP server tools (search_docs, get_document_by_url, etc.) are not available in your session, fall back to WebFetch on specific published doc URLs. Note both approaches in your report. The MCP only sees published docs. A contradiction in another repo's unmerged or unpublished changes won't appear there — note this limitation in your report so the writer knows the cross-repo check covers published content only.
Inputs
$ARGUMENTS is the file or directory containing the new or updated documentation. If empty, ask the user which file or directory to check.
Step 1: Read the new content
Glob for all .md files in $ARGUMENTS. Read each file fully.
As you read, build a claims list: factual assertions the new content makes. Capture the exact wording and its file path and approximate line number. Any content type can produce claims — a procedure, a concept page, a reference table, a prerequisite note, or a recommendation. Look for these claim types:
