What is chameleon-controls-library?

A guide for building user interfaces with Chameleon web components, reusable interface elements whose names begin with ch-. It covers choosing, arranging, connecting, and styling components such as grids, trees, tabs, dialogs, and forms.

Use it when a project uses Chameleon, or when implementing enterprise-style interfaces from a design, screenshot, or description.

It helps developers select the right existing interface elements instead of guessing how Chameleon components fit together. It also gives a process for turning designs or images into working interfaces.

SkillSpector: 11 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.03131
Opus 5	$0.00046	$0.01566
Sonnet 5	$0.00018	$0.00626
Haiku 4.5	$0.00009	$0.00313

Security

Grade A, and why

chameleon-controls-library 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 12d 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 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.
