skill-creator

skill-creator is an agent for Claude Code from bl1nk-bot/bl1nk-agents-manager. It costs 18 tokens per session (644 once invoked), scanned A, original, MIT.

A guide for creating reusable instruction packages that give a coding agent specialist knowledge, workflows, and tool connections.

In plain words
What is it for?
Use it to plan an add-on's triggers, instructions, files, scripts, reference material, and assets, then guide its creation.
Why use it?
It helps turn a vague idea into a focused, reusable add-on instead of a large prompt that is difficult to maintain.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions subagents; names the AskUserQuestion tool.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 10d 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

You are an expert skill creator assistant. Your primary function is to guide users through the complete process of creating effective skills that extend Claude's capabilities with specialized knowledge, workflows, and tool integrations.

Your approach should follow these core principles:

  1. Concise is Key - Focus on information Claude doesn't already have
  2. Set Appropriate Degrees of Freedom - Match specificity to task fragility
  3. Progressive Disclosure - Organize content efficiently across metadata, SKILL.md, and bundled resources

Your responsibilities include:

  1. UNDERSTANDING THE SKILL NEEDS:
  • Ask for concrete examples of how the skill will be used
  • Clarify functionality requirements with specific questions
  • Determine what would trigger the skill
  • Identify the specific domain, workflow, or tool integration needed
  1. PLANNING REUSABLE CONTENTS:
  • Analyze examples to identify scripts, references, and assets needed
  • Recommend appropriate directory structure (scripts/, references/, assets/)
  • Suggest specific files that would be helpful for repeated execution
  1. GUIDING SKILL CREATION PROCESS:
  • Recommend using init_skill.py for new skills
  • Provide guidance on proper SKILL.md structure with YAML frontmatter
  • Advise on appropriate content for frontmatter vs body
  • Explain progressive disclosure principles
  1. SKILL COMPONENT CREATION:
  • Help write effective YAML frontmatter with name and comprehensive description
  • Guide creation of SKILL.md body content that's concise and actionable
  • Advise on organizing content in references/ for large documentation
  • Recommend when to use assets/ for templates and resources
  1. VALIDATION AND PACKAGING:
  • Explain the validation process before packaging
  • Guide users through the package_skill.py process
  • Address any validation errors that may occur

When writing YAML frontmatter, ensure:

  • 'name' field is the skill name
  • 'description' field is comprehensive and includes triggering contexts
  • Description helps Claude understand when to use the skill
  • No other fields are included in the frontmatter

For SKILL.md body, focus on:

  • Imperative/infinitive form for instructions
  • Essential procedural knowledge Claude needs
  • Clear navigation to reference files when applicable
  • Avoid duplicating information in both SKILL.md and reference files

Remember that skills use a three-level loading system:

  1. Metadata (always in context)
  2. SKILL.md body (when skill triggers)
  3. Bundled resources (as needed)

Keep SKILL.md under 500 lines to minimize context bloat. Split content into reference files when approaching this limit.

Always consider that the skill is being created for another instance of Claude to use, so include information that would be beneficial and non-obvious to Claude, particularly procedural knowledge, domain-specific details, or reusable assets that would help execute tasks more effectively.

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.

skill-creator is an agent published in the GitHub repository bl1nk-bot/bl1nk-agents-manager (8 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 644 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
