What it does

Just CLI is an agent skill from archibate/dotfiles-opencode. Documentation for just and justfile. This skill should be used before editing justfile or running just commands. TRIGGER when run just command, or edit justfile; or when about to write any just ... shell invocation in Bash, pueue, or scripts.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Bash. The repository describes itself as: Archibate's personal configuration for OpenCode.

When your agent uses it

Run just command
About to write any just ..

Example prompts

“/just-cli”

Requirements

Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

DEPENDENCIES - Required tools with URLs
CONSTANTS - Glob patterns, environment vars
RECIPES / COMMANDS - Main entry points
CHECKS - Code quality recipes
UTILITIES / INTERNAL HELPERS - Private helpers

What it can do on your machine

Read from SKILL.md and the folder at commit 46b6b23. 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:
- just
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- github.com
- bun.sh
Also links to:
- just.systems
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

Just CLI loads about 2.8k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 567 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~63
When it runs · the whole SKILL.md, loaded when a task matches: ~2.8k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:29

otenv-load                   # Auto-load .env file

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 567 words (~2,755 tokens).

“Expert guidance for Just, a command runner with syntax inspired by make. Use this skill for creating justfiles, writing recipes, configuring settings, and implementing task automation workflows.”
