widgetize

widgetize is a command for coding agents from obiwancenobi/klamben. It costs 16 tokens per session (257 once invoked), scanned A, original, Apache-2.0.

A command that extracts an inline Flutter widget tree into a named reusable widget class, usually a StatelessWidget.

In plain words
What is it for?
It is for extracting a selected subtree, passing its data as parameters, documenting the new class, and replacing the original tree with the widget.
Why use it?
It helps shorten oversized build methods and isolate repeated or testable interface components without unnecessary file changes.

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

widgetize 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.

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

/widgetize

Extract a subtree into a reusable widget class.

When to use

  • A build method exceeds ~100 lines
  • Same tree repeats 3+ times
  • Prep for testing an isolated component

Actions

  1. Check design context: If .klamben.md exists in the project root, read it first. Apply the project's brand, platform targets, accessibility tier, and existing patterns to your work below.
  2. Identify the target subtree
  3. Create a new private StatelessWidget (or StatefulWidget if it has state) in the same file, below the parent class
  4. Pass captured variables as constructor parameters
  5. Add dartdoc to the new class
  6. Replace the inline tree with a call to the new widget

Do NOT

  • Move widgets to new files (unless the file is > 500 lines)
  • Make widgets public without user confirmation
  • Extract one-use widgets (YAGNI)
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.
