Ua1 Validator Agent OpenClaw Plugin & Skill | ClawHub

Looking to integrate Ua1 Validator Agent into your AI workflows? This free OpenClaw plugin from ClawHub helps you automate coding agents & ides tasks instantly, without having to write custom tools from scratch.

What this skill does

Validate PDFs against PDF/UA-1 using ua1.dev or api.ua1.dev from AI coding agents (OpenClaw, Claude Code, Codex, OpenCode). Use when an agent needs deterministic accessibility checks, compact machine-readable verdicts, CI gating, or structured remediation loops for PDF files.

Install

ClawHub CLI
openclaw skills install @hajekt2/ua1-validator-agent
Node.js (npx)
npx clawhub@latest install ua1-validator-agent

UA1 Validator Agent Skill

Use this skill to run deterministic PDF/UA-1 checks from an agent workflow.

Endpoints

  • Health: GET https://api.ua1.dev/api/health
  • Validate: POST https://api.ua1.dev/api/validate
  • Compact mode: POST https://api.ua1.dev/api/validate?format=compact
  • Metrics: GET https://api.ua1.dev/api/metrics

Required contract

Send multipart form-data with field name file.

  • Accepted: .pdf
  • Typical outcomes:
    • 200 validation response
    • 415 unsupported type
    • 413 file too large
    • 429 rate-limited

Minimal workflow for agents

  1. Run health check once before batch validation.
  2. Validate each PDF using compact mode for deterministic parsing.
  3. If verdict is fail, capture findings and group by rule_id.
  4. Produce remediation plan sorted by rule frequency.
  5. Re-run validation after fixes and compare counts.

Use script

Run:

bash scripts/validate_pdf.sh /absolute/or/relative/path/to/file.pdf

Optional env:

  • UA1_API_BASE (default: https://api.ua1.dev)
  • UA1_FORMAT (compact by default; set full for full payload)

CI gate pattern

Treat non-pass verdict as a failed quality gate.

  • Exit 0 only when verdict is pass
  • Exit 2 when verdict is fail
  • Exit 1 for transport/API errors

Use the script’s exit codes directly in pipelines.
