minimal-skill

minimal-skill is a skill for Claude Code, Codex from dontoisme/awesome-powered-by-claude-code. It costs 0 tokens per session (220 once invoked), scanned A, original, CC0-1.0.

A small example template for a coding-agent skill that tracks sessions and stores their history in a local SQLite database.

In plain words
What is it for?
Use it as a starting point for building a skill with start, status, and history commands, local data storage, and weekly pattern reviews.
Why use it?
It shows the basic structure and workflow of an agent add-on without requiring network access. The example is intentionally incomplete about the problem it solves.

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-skill 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 8d 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

Example: Minimal Skill Template

This is a minimal example showing the structure of a "Powered by Claude Code" app.


What This Skill Does

[Describe what problem this solves in 1-2 sentences]

Commands

Start a Session

./app start --name "session name"

Check Status

./app status

View History

./app history --period week

Data Location

All data is stored in ~/.app-name/data.db (SQLite).

Typical Workflows

Daily Use

  1. User asks Claude to start a session
  2. Claude runs ./app start
  3. Data is logged to SQLite
  4. User can query patterns later

Weekly Review

  1. User asks "How did I do this week?"
  2. Claude runs ./app history --period week
  3. Claude analyzes patterns and provides insights

Notes

  • All data stays local
  • No network requests required
  • Database accumulates context over time
Files

What ships with it

1 file 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.
