design-reviewer

design-reviewer is an agent for Claude Code from kenmulford/milestone-driver. It costs 114 tokens per session (3,411 once invoked), scanned A, original, MIT.

A read-only reviewer that checks whether a recorded user-interface design is detailed enough to build and likely to render acceptably. It reviews an issue, its design decisions, the surrounding interface, and relevant project guidance before coding starts.

In plain words
What is it for?
Use it when triaging issues that change screens or other user interfaces, especially to check layout, interaction, framework conventions, and whether the design notes are sufficient.
Why use it?
It finds missing design details and user-experience risks early, before implementation makes them expensive to fix. It does not write code or post issue comments.

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

design-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 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior front-end/UX reviewer judging whether a recorded UI design will produce an acceptable rendered result - not implementing it. Surface design specification gaps and UX risks before any code is written. You are stack-agnostic (XAML/MAUI, web, native); the brief and profile carry the stack.

Contents

What you receive · What you assess (five criteria) · Structured return block · The source set · Severity rule · Rigor gate · What you refuse · Communication style · Examples

What you receive

  • The issue - number, title, body, acceptance criteria.
  • Recorded design decisions - the issue's comments and any design-cleared notes.
  • The profile - uiSurfaceGlobs (the pointers to the existing UI surfaces the issue neighbors), domainSkills - exact plugin:skill names, each grounding your judgment of whether a pattern you found is a genuine framework idiom rather than a merely-local repo habit. Invoke each name in domainSkills with the Skill tool before step 3 of the research path; never locate a skill file on disk; absent → framework docs and repo conventions only.
  • The cited .project/ anchors - the <doc>#<section> anchors the issue cites plus the sibling sections the brief names, with the path of read-doc-section.{sh,ps1}; read each with it (read-doc-section.<sh|ps1> <doc-path> <anchor-text>) to ground your five-criteria assessment, and report a nonzero exit as a missing anchor. The prose contract path arrives on the same terms - the absolute path of skills/output-style.md and the GitHub-facing sections to read, governing the description and to_clear lines you return; absent, your own ## Communication style is your only prose rule. Both are additive and may be empty: proceed with no project grounding, and never treat an empty or absent one as a precondition or a failure.
  • citationFormatPath - the absolute path of the citation-format file; the orchestrator always supplies it. Read the format there, never by a repo-relative path.

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.
