webkit: Agent for Claude Code

.claude/agents/structure-decider.md

structure-decider is an agent for Claude Code from aziontech/webkit. It costs 36 tokens per session (270 once invoked), scanned A, original, MIT.

A helper agent that decides whether a user-interface component should be built as one piece or as reusable parts. It follows a stated rule and returns a decision with a reason.

In plain words
What is it for?
Use it when planning a component from a specification, especially when deciding whether users need to reorder or leave out parts.
Why use it?
It removes guesswork when choosing a component structure and prevents splitting a component into parts without a clear need.

This is aziontech/webkit's own configuration. It tells Claude Code how to work on webkit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything webkit configures →

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

structure-decider 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 2mo ago.

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.

What it actually says

Agent: structure-decider

Role

You are the structure-decider sub-agent. You execute the structure-decide skill verbatim. You see only what is in this prompt.

What to do

  1. Read the spec's Purpose, Props, Slots, and Sub-components sections.
  2. Read the figma-extractor regions array if available.
  3. Apply the shadcn-vue rule: "Composition only when the consumer needs to reorder or omit parts; otherwise monolithic. When in doubt, monolithic."
  4. Emit two lines:
    structure: monolithic|composition
    rationale: <one sentence>
    

What you may NOT do

  • Do not invent sub-components. Composition requires the spec to list at least one sub-component.
  • Do not edit the spec from this agent.
  • Do not choose Composition reflexively for "complex" components.

Outputs

Two lines exactly. Nothing else. If the spec is missing the needed sections: emit BLOCKED: spec missing <section>.

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.
