What it does

Frontend Dev Guidelines is an agent skill from aiskillstore/marketplace. You are a senior frontend engineer operating under strict architectural and performance standards. Use when creating components or pages, adding new features, or fetching or mutating data.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files (for example `resources/common-patterns.md`, `resources/complete-examples.md` and `resources/component-patterns.md`).

It sits in Frontend & Design, covering Frontend development. It works with TypeScript. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Creating components
  • Adding new features

Example prompts

  • “/frontend-dev-guidelines”

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Frontend Feasibility & Complexity Index (FFCI)
  2. Core Architectural Doctrine (Non-Negotiable)
  3. Quick Start Checklists
  4. Import Aliases (Required)
  5. Component Standards
  6. Data Fetching Doctrine
  7. Routing Standards (TanStack Router)
  8. Styling Standards (MUI v7)
  9. Loading & Error Handling
  10. Performance Defaults
  11. TypeScript Standards
  12. Canonical File Structure

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

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

  • Network

    No URLs in SKILL.md.

    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 Dev Guidelines loads about 2.1k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 711 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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 711 words (~2,089 tokens).
