sk-code-webflow is a skill for Claude Code, OpenCode from MichelKerkmeester/skilled-agent-harness_spec-driven-loops. It costs 44 tokens per session (4,591 once invoked), scanned A, original, MIT.

A frontend workflow for building, debugging, and checking browser-based Webflow pages and their client-side code.

In plain words
What is it for?
Use it for Webflow page changes, frontend performance fixes, deployment tasks, and browser debugging or verification.
Why use it?
It gives Webflow work a defined path from implementation through verification and connects the task to relevant HTML, CSS, and JavaScript guidance.

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

sk-code-webflow 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 4d ago.

The scan reads SKILL.md. This mod also ships 20 executable files (assets/animation/snippets/animate-on-scroll.js, assets/animation/snippets/cdn-bootstrap.js, assets/animation/snippets/es-module-bootstrap.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

webflow Surface — Frontend Evidence

Domain evidence and shared workflow doctrine for browser/Webflow frontend work. This surface owns the implement -> debug -> verify phases through the workflow references below, and acts on the evidence gathered here when the hub detects a Webflow surface. Detection markers: src/2_javascript, webflow, --vw- custom properties, CDN-delivered client scripts.

1. WHEN THE HUB BUNDLES THIS

  • The task touches Webflow-published pages, CDN-delivered webflow.js/client scripts, or src/2_javascript sources.
  • The active workflow phase needs frontend standards (CSS/HTML/JS), an implementation pattern, a performance remediation, a deployment step, or a browser debugging/verification procedure.
  • This surface owns edits, tests, and verification through the workflow references; hand off formal findings-first review to code-review and author-side quality gates to code-quality.

2. REFERENCE MAP

Language standards (load the detected language's trio; a frontend task legitimately spans all three):

  • CSS — references/css/style-guide.md, references/css/quality-standards/patterns-and-naming-enforcement.md, references/css/quality-standards/typography-autofill-and-color.md, references/css/quality-standards/focus-has-print-and-quick-reference.md, references/css/quick-reference.md, references/css/patterns/tokens-state-machine-and-triggers.md, references/css/patterns/data-attributes-and-forms.md, references/css/patterns/focus-accessibility-and-mobile.md, references/css/patterns/designer-component-and-performance.md, references/css/patterns/quick-reference-and-related.md
  • HTML — references/html/style-guide.md, references/html/quality-standards.md
  • JavaScript — references/javascript/style-guide/overview-naming-and-structure.md, references/javascript/style-guide/formatting.md, references/javascript/style-guide/commenting-and-related.md, references/javascript/quality-standards/init-dom-error-and-async.md, references/javascript/quality-standards/observer-validation-and-performance.md, references/javascript/quality-standards/state-and-cleanup.md, references/javascript/quality-standards/shared-listener-and-weakmap.md, references/javascript/quality-standards/enforcement-and-quick-reference.md, references/javascript/quick-reference.md

Changes

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.
