Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

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

Run health check once before batch validation. Validate each PDF using compact mode for deterministic parsing. If verdict is fail, capture findings and group by rule_id. Produce remediation plan sorted by rule frequency. 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.

Category context

Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
