minimal

minimal is a skill for Claude Code, Codex from nicolasmelo1/logion. It costs 52 tokens per session (290 once invoked), scanned A, original, MIT.

A minimal example of a Logion course, which is a packaged set of instructions for an AI agent. It contains only the files needed to validate a basic course and returns a fixed greeting.

In plain words
What is it for?
Scaffolding a new course, copying a valid minimal structure, editing its instructions and manifest, and validating the result before upload.
Why use it?
It provides a small starting structure for learning how a course is laid out and checked. It is not intended to perform a useful task by itself.

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

minimal 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 5d 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 it actually says

Minimal Logion Course

This is the smallest valid Logion course. It exists as a copy-paste starting point.

What this course does

Nothing meaningful — it returns the literal string "hello from minimal logion course" when an agent reads it.

Structure

minimal/
├── SKILL.md                  # this file
└── course/
    └── capabilities.yaml     # near-empty Logion manifest

No scripts/, no references/, no assets/. Add those when your real course needs them.

When to use this

When you're starting a new course and want a known-good skeleton that already validates against both:

  • the agentskills.io SKILL.md frontmatter spec
  • the Logion course/capabilities.yaml schema

Copy this whole directory, rename it, edit SKILL.md and course/capabilities.yaml, then run logion course validate ./your-course/ before uploading.

What an agent should do here

Nothing — this skill has no behavior. Real skills go in their body where this paragraph is.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
