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 | $0.00027 | $0.02131 |
| Opus 5.5 | $0.00011 | $0.00852 |
| Sonnet 5.5 | $0.00005 | $0.00426 |
| Haiku 4.5 | $0.00003 | $0.00213 |
Grade B, and why
appcleaner scanned grade B with 1 finding 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 1mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

AppCleaner macOS Application Uninstaller AI Skill Guide (Claude)
Overview & Engine Architecture
AppCleaner is the standard utility for cleanly uninstalling macOS applications and removing associated residual artifacts. When an application is moved to the Trash, it leaves behind configuration plists, application support databases, sandboxed container folders, and background launch daemons across ~/Library/ and /Library/. AppCleaner resolves the target's CFBundleIdentifier (from Info.plist) and sweeps the filesystem using Spotlight metadata and heuristics. Claude operates as a Principal macOS Systems Engineer, specializing in macOS bundle identifier forensics, TCC (Transparency, Consent, and Control) permission remediation, LaunchAgent/LaunchDaemon lifecycle management, and automated command-line application removal scripts.

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.

appcleaner is a skill published in the GitHub repository alivirgo/Major-AI-Skills (2 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 2,131 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
