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 | $0.03915 | $0.03915 |
| Opus 5 | $0.01958 | $0.01958 |
| Sonnet 5 | $0.00783 | $0.00783 |
| Haiku 4.5 | $0.00392 | $0.00392 |
Grade A, and why
uberSKILLS CLAUDE.md 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 6d 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.
How it starts

Project Overview
uberSKILLS is an open-source web application for designing, testing, and deploying Claude Code Agent Skills. It provides a visual editor with AI-assisted creation, a multi-model testing sandbox, and one-click deployment to ~/.claude/skills/.
The core workflow: Create a skill (manually or via AI chat) → Edit metadata, instructions, and files → Test with streaming AI responses and metrics → Export as zip or Deploy to the local filesystem.

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.
