Core AgentUse usage guide. An agent skill from agentuse/agentuse.

  • SKILL.md covers Skill Catalog, Load A Specialized Builtin Skill, Entrypoints and Schedules, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Core is an agent skill from agentuse/agentuse. Core AgentUse usage guide. Read this before running AgentUse commands. Covers the builtin skill catalog, installed skill inspection, agent discovery, running agents, creating agents, sessions, server usage, schedules, and when to load specialized AgentUse builtin skills.

Its SKILL.md is about 700 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: 🤖 AI agents on autopilot. Any model. Runs local, cron, CI/CD, or Docker.

Example prompts

  • “/core”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e524de. 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 bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.agentuse.io

    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

Core loads about 700 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~700

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 219 words (~700 tokens).

“AgentUse runs AI agents from natural-language markdown files. Agents live in .agentuse files and can use tools, skills, subagents, approval gates, stores, sessions, schedules, and the AgentUse HTTP server.”
