create-skill

create-skill is a skill for Claude Code, Codex from onurpolat05/ALBA. It costs 112 tokens per session (1,107 once invoked), scanned A, original, MIT.

An interactive workflow for creating a new Claude Code skill, which is a reusable instruction set triggered by specific phrases. It gathers the skill's purpose, triggers, inputs, outputs, and tool needs before writing its files.

In plain words
What is it for?
Use it when you want to turn a repeated workflow into a new slash command or reusable skill.
Why use it?
It helps define a skill clearly and avoid conflicts with existing skills.

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

create-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 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.

ALBA Skill Creator

Interactively create a new skill with proper frontmatter and structure.

Process

Step 1: Understand the Skill

Ask these questions (one at a time):

  1. "What should this skill do?" - Core purpose in one sentence
  2. "What exact phrases should trigger it?" - Push for the words the user actually types, not abstract categories. "research", "look into X", "find info on" beats "information gathering".
  3. "When should it NOT fire?" - The nearest existing skill it could be confused with. This answer becomes the Do NOT use for ... clause and is what stops two skills fighting over the same prompt.
  4. "What inputs does it need?" - What the user provides
  5. "What output should it produce?" - Format, structure
  6. "Does it need web access or just local files?" - Determines tools and context

Step 2: Determine Configuration

Based on answers, decide:

Context:

  • inline - Quick operations that need conversation context (< 1 min), or anything that asks the user a question
  • fork - Heavy operations that should run as a subagent (research, log analysis, wide file sweeps). A fork keeps its own reading out of the main context window.

If you choose fork, you must also decide background. Forked skills default to background: true — they detach and report back later. Set background: false when the user is waiting for the answer in the same turn, which is the normal case for an interactive skill. Leave the default only for genuinely fire-and-forget work. (background needs Claude Code v2.1.218+.)

Tools: Pick from:

  • Read, Write, Edit, Glob, Grep (file operations)
  • WebSearch, WebFetch (web access)
  • Bash (system commands)
  • AskUserQuestion (user interaction - only works with inline; a fork has no one to ask)

Optional fields worth considering: argument-hint if the skill takes arguments, disable-model-invocation: true if firing it by accident would damage something, model if the work is mechanical enough to run on a cheaper model. Full reference with every valid field: templates/skills/SKILL-TEMPLATE.md.

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.
