spec-create

An interactive command for drafting a Markdown specification for a new webkit component. It can gather details from a Figma design or ask for the component's name, category, behavior, and other requirements.

In plain words
What is it for?
Use it to create a draft component specification, review it, mark it approved, and then start component creation.
Why use it?
It records the component's intended interface before code is written. This reduces guesswork, especially when there is no existing design to use as a source of truth.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 44 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,330 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

spec-create 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are creating a new component spec for .specs/<name>.md. Follow the spec-create skill in .claude/skills/spec-create/SKILL.md exactly.

User input: $ARGUMENTS

Two modes — pick one up front

spec-create has two distinct paths. Detect the mode from the arguments (and confirm with the user before drafting):

  • Mode A — Figma-driven (--figma <url> present). The Figma frame is the source of truth: extract tokens/regions/states, map them to DESIGN.md, and ask the user only where the frame is silent (behavior, a11y intent, story list). The component name is derived from the frame's component name (normalized to kebab, confirmed with the user); passing <name> is optional here and, when given, overrides the frame.
  • Mode B — Name + Category (no --figma; the user is building without a design). There is no ground truth, so invention risk is highest. This mode is deliberately more blocking: it always asks about every section, one at a time, never infers props/events/tokens, and refuses to write until each mandatory section has a real answer (no silent TBD). --category is required here (ask + confirm if missing).

If --figma is absent, you are in Mode B — do not quietly infer from intent. If both a URL and "no figma" intent are ambiguous, ask which mode the user wants before proceeding.

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.

spec-create is a command published in the GitHub repository aziontech/webkit (2 stars, last pushed 3d ago), licensed MIT. It adds 44 tokens to every session and 1,330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
