ux-acceptance-coordinator

ux-acceptance-coordinator is a skill for Claude Code, Codex from emdash-cms/emdash. It costs 59 tokens per session (677 once invoked), scanned A, original, MIT.

A coordinator for black-box UX acceptance tests, where a separate tester follows a user journey through a disposable website and reports what happens.

In plain words
What is it for?
Use it to prepare browser journeys, dispatch an isolated tester, and verify the reported outcome.
Why use it?
It keeps test setup, success checks, and product diagnosis separate from the tester’s user-facing experience.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ux-acceptance-coordinator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Coordinate UX acceptance testing

Run a goal-driven browser journey with a tester that has no repository context. Keep site preparation, private success checks, and product diagnosis in the coordinator context.

Prepare the run

  1. Read the selected journey in acceptance/journeys/.

  2. Check the journey's status and requires frontmatter. If its status is needs-profile, report the missing bootstrap requirements and stop. Do not substitute a simpler profile or relax the journey.

  3. Read its site profile in acceptance/sites/ and the portable tester instructions in acceptance/tester/SKILL.md.

  4. Choose the journey's target. Use Node unless the journey or change under test requires the Cloudflare runtime.

  5. Start one disposable site:

    pnpm ux:site:start -- --target node --profile editorial-small
    
  6. Keep the run ID, start URL, and run-data path from the command output. Never send the run-data file or API token to the tester.

Isolate the tester

Create the tester outside the repository checkout. Give it only:

  • the contents of acceptance/tester/SKILL.md;
  • the journey's Tester brief section;
  • the generated start URL;
  • a writable location for its report and screenshots.

Do not give the tester AGENTS.md, repository skills, source files, route names, the coordinator checks, or implementation context. Do not describe a clean context as isolated when the selected agent mechanism still exposes the checkout. If the environment cannot create a separate context within the user's authorization, prepare the handoff and ask the user to launch it.

Use any agent implementation that provides browser control. Do not translate the brief into tool-specific click instructions.

Verify and report

Wait for the tester to finish or explicitly give up. Preserve its action log, screenshots, and report without rewriting its observations.

Run the journey's Coordinator checks independently. Prefer a read-only public API with the local token in the run-data file; use direct database inspection only when the public surface cannot establish the result. The tester's claim is not proof of completion.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
