What is uberSKILLS CLAUDE.md?

Repository instructions for uberSKILLS, an open-source web application for creating, testing, and deploying Claude Code Agent Skills. A monorepo is one repository containing several related packages; this project uses one for its web app and supporting code.

Use them when editing the skill editor, AI testing sandbox, deployment or export flow, database code, user interface, or automated tests.

They document the project’s structure, technologies, and main workflow from skill creation through testing and deployment. This helps changes fit the correct application layer and package.

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	$0.03915	$0.03915
Opus 5.5	$0.01566	$0.01566
Sonnet 5.5	$0.00783	$0.00783
Haiku 4.5	$0.00392	$0.00392

Security

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 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.

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.
