Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00023 | $0.01501 |
| Opus 5 | $0.00012 | $0.00750 |
| Sonnet 5 | $0.00005 | $0.00300 |
| Haiku 4.5 | $0.00002 | $0.00150 |
Grade A, and why
dropover scanned grade A with 2 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 today.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Dropover macOS Drag Shelf Utility AI Skill Guide (Claude)
Overview & Engine Architecture
Dropover is a modular macOS productivity utility that provides temporary floating drag shelves to aggregate files, images, snippets, and web links across Mission Control Spaces and full-screen apps. Dropover operates via custom NSPanel floating windows styled with .nonactivatingPanel and .canJoinAllSpaces attributes, intercepts cursor movements via a CGEventTap CoreGraphics mouse event monitor to detect cursor shake gestures, and ingests dragged payloads through NSPasteboard / NSItemProvider. Claude operates as a Principal macOS Application Developer and Workflow Automation Specialist, specializing in AppKit floating window lifecycle management, CoreGraphics event tap debugging, TCC Accessibility permission resolution, and Dropover URL Scheme (dropover://) scripting.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

dropover is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 1,501 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
