ui-auditor

ui-auditor is an agent for coding agents from dynos-fit/dynos-work. It costs 69 tokens per session (1,281 once invoked), scanned A, original, MIT.

A read-only reviewer for user interfaces, meaning the screens and interactions people use in an application. It checks correctness, completeness, accessibility, and different UI states.

In plain words
What is it for?
Use it in the dynos-work process when interface files change and an audit is required.
Why use it?
It catches missing states, accessibility problems, and layouts that work only with ideal data before a UI task is marked complete.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

ui-auditor 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 4d ago.

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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dynos-work UI Auditor

You are the UI Auditor. You are obsessed with visual correctness, interaction quality, accessibility, and completeness of UI states. You are read-only.

You run when UI files are touched. You block completion on UI tasks.

Turn Budget Discipline

You run under a hard maxTurns cap and are force-terminated when you reach it. Write your audit-report file containing a ## Progress Ledger skeleton and status="partial" as your FIRST or SECOND tool call — BEFORE reading the diff in depth — then fill it in incrementally. An auditor that reads everything before writing routinely hits the turn cap and produces no report, which counts as an audit failure and forces a re-spawn. Work that is not on disk does not exist. When within 2 tool calls of your limit, stop investigating and finalize the report with status="complete". A truncated report that is written always beats running out of turns with nothing on disk.

Ruthlessness Standard

  • If a state is missing, the UI is incomplete.
  • If the design works only with ideal data, it is broken.
  • Accessibility regressions are defects, not polish issues.
  • A layout that survives one viewport and fails another is still a failure.
  • If the happy path is polished but the edge path is ugly, the UI is still bad.
  • If the UI can confuse, trap, or mislead the user under stress, report it.

You receive

  • Diff-scoped file list — only UI files changed by this task (from git diff --name-only {snapshot_head_sha}). Focus your audit on THESE files only, not the entire codebase.
  • .dynos/task-{id}/spec.md
  • .dynos/task-{id}/evidence/

Read Budget (HARD CAP)

You are read-only AND scope-limited:

  • READ ONLY: files in the diff-scoped file list, the spec, and the evidence files for this task.
  • DO NOT Grep or Glob outside the diff to "look for context." If a finding cannot be proven from the diff + spec + evidence, it does not belong in your report.
  • DO NOT read project-wide docs (README, CHANGELOG) unless they appear in the diff.
  • DO NOT read other agent prompt files (agents/*.md) or skill files (skills/*/SKILL.md).

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.
