skill-create

skill-create is a skill for Claude Code, Codex from ww-w-ai/bkit-claude-code. It costs 20 tokens per session (996 once invoked), scanned A, original, Apache-2.0.

An interactive workflow for creating project-local skills: reusable instructions that teach an agent how to perform a specific task in one project.

In plain words
What is it for?
Use it to define a skill, inspect the project and its conventions, choose allowed tools and triggers, and generate a local SKILL.md file.
Why use it?
It turns a project need into a documented, consistently triggered workflow instead of requiring the same instructions to be given repeatedly.

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-create 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 yesterday.

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.

skill-create - Interactive Skill Creation Workflow

프로젝트 컨텍스트를 분석하여 project-local 스킬을 생성하는 워크플로우.

Workflow Steps

Step 1: Gather Information

If /skill-create (no args):

  1. Ask user for skill name (kebab-case)
  2. Ask user for skill purpose/description
  3. Ask user for classification: workflow or capability

If /skill-create {name}:

  1. Use provided name
  2. Analyze project context to infer purpose
  3. Ask user to confirm/modify

If /skill-create from-btw {btw-id}:

  1. Read btw suggestion from .bkit/btw-suggestions.json
  2. Use suggestion text as seed for skill description
  3. Use suggestion context for project context

Step 2: Analyze Project Context

  1. Read CLAUDE.md for project conventions
  2. Scan project structure:
    • Identify tech stack (Java/Spring, Next.js, Python, etc.)
    • Find relevant patterns in source code
    • Check existing project-local skills for overlap
  3. Determine appropriate:
    • Allowed tools for the skill
    • Trigger keywords (Korean + English)
    • Related files/patterns to reference

Step 3: Generate SKILL.md

Create .claude/skills/project/{name}/SKILL.md with:

---
name: {name}
classification: {workflow|capability}
classification-reason: "{reason based on analysis}"
deprecation-risk: none
effort: low
description: |
  {Generated description}
  Triggers: {trigger commands}
  Keywords: {keywords in Korean and English}
argument-hint: "{usage hint}"
user-invocable: true
allowed-tools:
  - Read
  - Write
  - Edit
  - Glob
  - Grep
  - Bash
---

Body content includes:

  • Purpose and when to use
  • Step-by-step instructions for workflow skills
  • Pattern reference for capability skills
  • Code examples from actual project files
  • Integration points with other skills

Step 4: Generate Eval Files (optional)

Create evals/{name}/ directory with:

evals/{name}/
  eval.yaml        - Test configuration
  prompt.txt       - Test prompt
  expected.txt     - Expected behavior description

eval.yaml format:

name: "{name} skill eval"
skill: ".claude/skills/project/{name}/SKILL.md"
tests:
  - name: "basic trigger"
    prompt: "{trigger command}"
    expected:
      - "{expected behavior 1}"
      - "{expected behavior 2}"
  - name: "edge case"
    prompt: "{edge case prompt}"
    expected:
      - "{expected behavior}"

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.
