content-validator

Job

Run <plugin_root>/scripts/lint/lint_runner.py on the given paths with the host config, then run any LLM-based semantic checks not implementable as scripts (voice_consistency from spec §6.2). Aggregate into one structured result.

Inputs

• paths: list of file paths the orchestrator just authored/edited
• config_path: path to the host's .engineering-docs-agent/config.yml
• voice_samples: voice sample bundle (only used if voice_consistency is enabled in tier 2)
• plugin_root: absolute path to the engineering-docs-agent plugin checkout. The lint runner lives at <plugin_root>/scripts/lint/lint_runner.py. The plugin is vendored separately from the host repo (e.g. at .docs-agent-plugin/ in CI), so this path is not host-relative.

Output schema (canonical)

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "content-validator output",
  "type": "object",
  "required": ["passed", "failed"],
  "properties": {
    "passed": {
      "type": "array",
      "items": {
        "type": "object",
        "required": ["path"],
        "properties": {
          "path": { "type": "string" },

}

Return ONLY a JSON object that validates against this schema. No prose, no markdown fences around the response, no commentary.

Output contract

The canonical schema is in §Output schema above. The shape described here is the same; the schema is authoritative if they disagree.

{
  "passed": [{ "path": "...", "rules": ["..."] }],
  "failed": [
    { "path": "...", "rule": "...", "message": "...", "severity": "block" }
  ]
}

Procedure

1. Run python <plugin_root>/scripts/lint/lint_runner.py --config <config_path> --paths <paths...> --json. Substitute the literal value of plugin_root from the input — do not assume the runner is on $PATH or at a relative path. Quote the plugin_root path if it contains spaces.
2. Parse aggregated output. For each per-rule result, extract pass/fail per path with severity.
3. If voice_consistency is enabled in config and not implemented as a script, perform LLM check: for each path, compare prose against voice_samples; flag mismatch as severity: block, message describing the mismatch.
4. Build the structured response with two lists.

Failure handling

If lint_runner.py exits non-zero AND output is unparseable, return {failed: [{path: "*", rule: "lint_runner", message: "runner crashed at <plugin_root>/scripts/lint/lint_runner.py: <stderr>", severity: "block"}]}.
