What it does
Calctl is an agent skill from CraftOS-dev/CraftBot. Manage Apple Calendar events via icalBuddy + AppleScript CLI
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `_meta.json`).
The repository describes itself as: One agent. Every kind of work. The licence is MIT.
Example prompts
- “/calctl”
What it can do on your machine
Read from SKILL.md and the folder at commit b50970c. 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
Shell commands in SKILL.md call:
brew
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
Calctl loads about 454 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 120 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.
