What it does

Bendc Frontend Guidelines is an agent skill from Asymmetric-al/core. HTML, CSS, and JavaScript craft guidelines from bendc/frontend-guidelines — semantics, a11y basics, selector discipline, motion-friendly CSS, and readable JS. Use for markup review, static HTML/CSS, email HTML, or general front-end hygiene; pair with repo frontend rules and TypeScript lint policy.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/readme-original.md` and `references/upstream.md`).

It sits in Frontend & Design, covering Accessibility. It works with JavaScript and TypeScript. The repository describes itself as: A high-performance, enterprise-grade Next.js 16 application for mission-focused non-profit organizations. Built for high impact teams. The licence is AGPL-3.0.

When your agent uses it

  • Static HTML/CSS
  • General front-end hygiene
  • Pair with repo frontend rules and TypeScript lint policy

Example prompts

  • “/bendc-frontend-guidelines”

Workflow steps

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

  1. Confirm the surface is in scope (markup, styles, or JS where the upstream checklist applies).
  2. Load references/readme-original.md (or skim the sections you need: HTML, CSS, JavaScript).
  3. Cross-check Precedence above before recommending a change that touches tokens, Tailwind, motion, JS/TS code shape, or TS types.
  4. For shared UI or app routes, reconcile recommendations with docs/ai/rules/frontend.md and nearby components.
  5. Prefer small, evidence-based edits; do not rewrite large areas solely to match upstream brevity examples if repo style differs.

What it can do on your machine

Read from SKILL.md and the folder at commit c30c8ff. 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:

    • bun

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.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

Bendc Frontend Guidelines loads about 1.4k tokens when it runs, and up to ~5.6k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 487 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
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
~5.6k

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.

bendc Frontend Guidelines

Triggers

Use this skill when the task benefits from foundational HTML, CSS, and vanilla JS craft guidance from the vendored bendc/frontend-guidelines checklist, including:

  • Semantic HTML, document structure, lang, charset, and meaningful elements (main, article, time, etc.)
  • Accessibility basics called out upstream: alt text, real links and buttons, not relying on color alone, labelling controls
  • CSS structure: selector weight, avoiding unnecessary !important, inheritance, shorthand, flow and layout (flex/grid over absolute positioning when appropriate)
  • CSS performance habits: prefer opacity / transform for animation; avoid animating layout-heavy properties (aligns with repo motion rules)
  • Vanilla or legacy JS style: readability, native APIs, avoiding foot-guns called out in the upstream doc

Also load docs/ai/rules/frontend.md for any apps/* or packages/ui work in this monorepo.

Do not use when

  • The task is strictly backend, migrations, or database-only work.
  • You only need React / Next.js / App Router patterns — prefer docs/ai/skills/nextjs-app-router/SKILL.md and framework docs.
  • You only need Tailwind, design tokens, or shared @asym/ui primitives — the upstream doc is not Tailwind-specific; follow docs/ai/rules/frontend.md first.

Precedence (this repo wins)

The full text of the upstream guide lives in references/readme-original.md. When that reference conflicts with the Precedence table below, follow the table.

TopicAuthoritative in this repo
Tailwind, Maia/Zinc tokens, cn(), no arbitrary hex in componentsdocs/ai/rules/frontend.md
Motion timing, tokens, reduced motion, transition-all ban, route view transitionsdocs/ai/rules/frontend.md, docs/ai/skills/emil-design-engineering/SKILL.md, docs/ai/skills/anim/SKILL.md
General JavaScript / TypeScript code shape, control flow, helper extractionESLint, TypeScript configuration, formatter output, and nearby source patterns — prefer explicit, straightforward code over upstream terseness, loop avoidance, recursion, or shorthand
TypeScript types, strict, equality (===), linted patternsESLint / TS config and existing code style — do not adopt upstream examples that rely on loose equality or patterns that fail lint here
React component structure, Server Components, hooksNext.js docs and docs/ai/skills/react-component-dev/SKILL.md

Use the bendc guide as a second opinion on semantics, DOM clarity, CSS discipline, and readable JS. Do not copy upstream JavaScript advice about terseness, avoiding loops, recursion, composition, or shorthand unless it improves clarity under this repo's AGENTS.md conventions.

Workflow

  1. Confirm the surface is in scope (markup, styles, or JS where the upstream checklist applies).
  2. Load references/readme-original.md (or skim the sections you need: HTML, CSS, JavaScript).
  3. Cross-check Precedence above before recommending a change that touches tokens, Tailwind, motion, JS/TS code shape, or TS types.
  4. For shared UI or app routes, reconcile recommendations with docs/ai/rules/frontend.md and nearby components.
  5. Prefer small, evidence-based edits; do not rewrite large areas solely to match upstream brevity examples if repo style differs.

Checklist

  • Confirmed triggers match (HTML/CSS/JS craft vs pure React/Next/backend).
  • Read the relevant sections of references/readme-original.md or the live upstream README.
  • Applied Precedence: repo frontend rules, motion skills, AGENTS.md code style, and TypeScript lint are satisfied.
  • Did not strip accessibility or semantics for brevity.
  • If you edited files under docs/ai/skills/bendc-frontend-guidelines/, ran bun run skills:sync and bun run skills:verify before committing.
