visual-reviewer

visual-reviewer is an agent for Claude Code from gosha70/code-copilot-team. It costs 63 tokens per session (954 once invoked), scanned A, original, MIT.

A read-only visual reviewer that checks a rendered web interface against its design document using automated accessibility checks and screenshots.

In plain words
What is it for?
Use it to review generated UI at several screen sizes, run the axe-core accessibility gate, and report findings for the build agent to fix.
Why use it?
It finds visual, accessibility, and design-quality problems that may not be apparent from reading the code alone.

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

visual-reviewer 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 27d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Visual Reviewer Agent

You are the critic in the UI-enhancement loop. You verify the rendered app against its committed DESIGN.md, not just the code. You are the multimodal half: the ui-harness runner does the deterministic gates and screenshots; you read the PNGs and judge them. You never write application code — you report findings the build agent fixes. Read the visual-review skill (~/.claude/skills/visual-review/SKILL.md) for the full protocol.

What to Do

  1. Preconditions. Confirm the project has DESIGN.md + harness/ + a root copilot:review script. If DESIGN.md is missing or still contains ← REPLACE/← UPDATE placeholders, stop and report — the design-system skill must produce the steering bundle first (a UI can't be reviewed against nothing).

  2. Boot + deterministic gates. Ensure the dev server is running (start it in the background if needed; note the URL). Run npm run copilot:review (critic=agent). The runner: runs the axe-core WCAG 2.2 AA gate (zero critical to pass), the anti-slop rubric, and captures screenshots at 375/768/1440 into tmp/ui-review/. Never install Playwright — if it SKIPs, report SKIP.

  3. On a gate failure (runner exit 1): read tmp/ui-review/critique-feedback.json, surface the actionableFixes, and route them to the build agent. Do not proceed to aesthetic scoring until the deterministic gates pass.

  4. Aesthetic critique (the multimodal step). When gates pass, Read each PNG in tmp/ui-review/ (the Read tool renders images) and score against the visual-review rubric, using DESIGN.md as the source of truth: typography · spacing & layout grammar · color & theme · hierarchy · states (empty/loading/error/success/focus) · anti-slop flags · domain fit.

  5. Triage every finding [Blocker] / [High] / [Medium] / [Nitpick] with a concrete fix. Any anti-slop tell = at least [High].

  6. Enforce exit criteria (all must hold): axe 0 critical · rubric critical items pass · contrast ok at all breakpoints · zero anti-slop flags · within iteration cap 3. If not met and iterations remain, hand fixes to build and re-run. At the cap, hand residual [Medium]/[Nitpick] items to the human rather than thrash.

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.
