skill-creator

skill-creator is a skill for Claude Code from korbinjoe/TeemAI. It costs 45 tokens per session (462 once invoked), scanned A, original, MIT.

A guide for creating or updating reusable coding-agent skills, including their instructions, supporting files, triggers, and checks.

In plain words
What is it for?
Use it to build skill directories, write SKILL.md files, add references or scripts, define required tools, and document verification steps.
Why use it?
It provides a repeatable structure so a new skill is understandable, appropriately scoped, and testable instead of being a one-off procedure.

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

skill-creator 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 6d 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

skill-creator

Use this skill to create a reusable skill directory with a SKILL.md and any supporting references/, scripts/, or assets that the skill needs.

Core principles

  • A skill should encode a repeatable workflow, not a one-off answer.
  • Trigger rules must be specific enough that the agent knows when to use the skill and when to skip it.
  • Keep the main SKILL.md short enough to load quickly; move long domain details into references/.
  • Prefer scripts or templates for large reusable artifacts instead of asking the model to recreate them from memory.
  • Avoid hidden dependencies. List required CLIs, services, credentials, and environment variables in the skill.

Required SKILL.md shape

Every skill must start with YAML frontmatter:

---
name: skill-name
description: >
  What this skill does and the situations that should trigger it.
allowed-tools: Read, Write, Edit, Glob, Grep, Bash
---

The body should include:

  • When to use the skill.
  • When not to use it.
  • The workflow the agent should follow.
  • Any files or references the agent must read before acting.
  • Verification steps or expected outputs.

Directory layout

skills/<skill-name>/
  SKILL.md
  references/        # optional long-form instructions
  scripts/           # optional executable helpers
  templates/         # optional starter artifacts

Quality checklist

  • The skill name is lowercase kebab-case and matches its directory.
  • The description contains concrete trigger language.
  • Instructions are imperative and operational.
  • The skill does not duplicate unrelated agent personality or global policy.
  • References are only loaded when relevant.
  • Scripts are executable when they are intended to run directly.
  • The skill includes verification guidance for its common outputs.

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.
