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 | $0.00049 | $0.02442 |
| Opus 5 | $0.00024 | $0.01221 |
| Sonnet 5 | $0.00010 | $0.00488 |
| Haiku 4.5 | $0.00005 | $0.00244 |
Grade E, and why
sandbox-escape-techniques scanned grade E 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 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
cat /proc/1/root/etc/shadow # read host files Encoded or obfuscated payloadhighSupply chain
base64 or hex that is decoded and executed hides what actually runs from anyone reading the file.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

sandbox-escape-techniques is a skill published in the GitHub repository Prohao42/aimy-skill (164 stars, last pushed 2d ago), with no licence file. It adds 49 tokens to every session and 2,442 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it E with 2 findings (reaches for credential files, encoded or obfuscated payload). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
