.opencode/skill/library-management/SKILL.md

library-management is a skill for OpenCode from Th0rgal/sandboxed.sh. It costs 51 tokens per session (951 once invoked), scanned A, original, no licence file.

A tool for managing a Sandboxed.sh library of agent add-ons, including skills, commands, tools, rules, and integrations.

In plain words
What is it for?
Searching the library and saving or creating skills, agents, commands, tools, rules, or integrations.
Why use it?
It gives agents a way to find and maintain the reusable instructions and tools stored in that library.

Skill for OpenCode

Written for OpenCode: installed under .opencode/.

This is Th0rgal/sandboxed.sh's own configuration. It tells OpenCode how to work on sandboxed.sh itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sandboxed.sh configures →

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.

Security

Grade A, and why

library-management 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 9d 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.

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.
