What it does

Frontend Code Review is an agent skill from aiskillstore/marketplace. Review Dify frontend code for correctness, accessibility, component design, dify-ui usage, data/query boundaries, performance, and tests. Trigger for .tsx, .ts, .js, UI, React, Next.js, pending-change, or focused frontend review requests.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/accessibility-ui.md`, `references/code-quality.md` and `references/component-architecture.md`).

It sits in Frontend & Design, covering React components, Code review and Accessibility. It works with Dify, Next.js and React. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Focused frontend review requests
  • Tasks that involve React components
  • Tasks that involve Code review

Example prompts

  • “/frontend-code-review”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify the review scope. For pending changes, inspect git diff --stat, git diff, and staged diff if relevant. For file-focused reviews…
  2. Read code around the changed lines and the owning module. Do not review by isolated snippets when nearby ownership, labels, query inputs…
  3. Check user-visible regressions first: accessibility, broken interaction, auth/permission leaks, query/hydration errors, data loss…
  4. Then check maintainability and performance: ownership, effects, wrappers, memoization, bundle/waterfall risks, tests, and design-system…
  5. Report only actionable findings. Do not list speculative risks, style preferences, or broad refactors unless they are directly tied to a…

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • raw.githubusercontent.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Frontend Code Review loads about 1.4k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 574 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 574 words (~1,410 tokens).

“Use this skill when the user asks to review, audit, analyze, or sanity-check frontend code under web/, packages/dify-ui/, or frontend-adjacent TypeScript files.”
