Validates a DITA 1.3 topic file against structural and semantic rules derived from the official DITA 1.3 DTDs. Use this skill when you need to check a concept, task, reference, troubleshooting, glossentry, or base topic for missing required elements, incorrect nesting, duplicate IDs, malformed conref/keyref, or shortdesc quality issues. Returns structured JSON with errors and warnings.

Overview

Validates a DITA 1.3 XML topic and returns a JSON report listing all errors and warnings.

Usage

# Validate a file
python scripts/validate_dita_topic.py path/to/topic.dita

# Pipe XML directly
cat topic.dita | python scripts/validate_dita_topic.py -

# Enforce a specific topic type (fails if root element doesn't match)
python scripts/validate_dita_topic.py topic.dita concept

Output schema

{
  "is_valid": true,
  "errors": [
    { "element": "string", "rule": "string", "message": "string", "line": 0 }
  ],
  "warnings": [
    { "element": "string", "rule": "string", "message": "string", "line": 0 }
  ]
}

Exit code is 0 when is_valid is true, 1 otherwise.

Rules applied

See references/RULES.md for the full rule catalogue.

Key rules per type:

TypeRequired bodyKey extra rules
concept<conbody>No task/ref elements inside conbody
task<taskbody>Each <step> needs <cmd>; singletons enforced
reference<refbody><property> row quality checks
troubleshooting<troublebody>At least one <troubleSolution>
glossentry(n/a)<glossterm> and <glossdef> required

Common edge cases

  • A topic with a valid root but no @id → Error (not Warning)
  • <shortdesc> containing <p> or other block elements → Warning
  • @conref without a # fragment separator → Error
  • Duplicate @id values → Error (only first occurrence is valid)
  • <steps> with more than 10 <step> children → Warning (split recommended)

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
