What it does
Golem Permission Card Moonbit is an agent skill from golemcloud/golem. Transfers opaque permission-card handles through MoonBit schema values. Use when delegated authority crosses a dynamic tool or middleware boundary.
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…
When your agent uses it
- Delegated authority crosses a dynamic tool
- Middleware boundary
Example prompts
- “Use the golem-permission-card-moonbit skill to transfer opaque permission-card handles through MoonBit schema values”
- “/golem-permission-card-moonbit”
What it can do on your machine
Read from SKILL.md and the folder at commit 8bed66c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are moonbit).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Golem Permission Card Moonbit loads about 315 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 117 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 117 words (~315 tokens).
“Import the low-level schema model and core WIT types in moon.pkg:”
- name
- golem-permission-card-moonbit
