skill-creator

A meta-skill for creating new SKILL.md files. A skill is a reusable set of instructions that guides an agent through a particular workflow.

In plain words
What is it for?
Turning a clearly described workflow into a correctly structured skill, adapting external commands, or creating several skills for a new area.
Why use it?
It removes the need to work out the repository’s required skill-file structure and front matter by hand.

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 2d 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.

The opening of the file, as written. The whole thing — 318 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Creator

A meta-skill that produces new SKILL.md files. Describe what the skill should do, and this skill generates a complete, convention-compliant SKILL.md file ready to commit.

When to Use

  • You want to add a new skill but are unsure of the required structure
  • You have a workflow in mind and want to formalize it as a skill
  • You are migrating a skill from another source and need to adapt it to this repo's format
  • You need to translate an external slash-command or Claude-oriented pattern into Copilot-native primitives
  • Bootstrapping multiple skills quickly for a new domain

When NOT to Use

Instead of skill-creator Use
Editing an existing skill edit tool directly
Creating an agent definition See agents/ directory conventions in AGENTS.md
Writing an orchestration pattern See orchestration/patterns/

Prerequisites

  • A clear description of the workflow the skill should encode
  • Knowledge of which skills/ subdirectory it belongs to:
    • development/ — coding, debugging, testing workflows
    • security/ — security scanning, review, hardening
    • testing/ — test strategy, eval, coverage
    • documentation/ — doc generation, update workflows
    • content/ — copywriting, SEO, content strategy
    • product/ — PRD, launch, roadmap
    • workflow/ — process workflows (research, release, sprint)
    • copilot-exclusive/ — GitHub Copilot CLI-specific features
  • Confirm the category already exists in this repository. Research-focused skills currently live under workflow/; adding a new category requires updating the shared allowlist in scripts/skill-metadata.js before introducing new files.

Workflow

1. Gather requirements

Ask (or determine from context):

1. What is the skill name? (kebab-case, e.g., `api-versioning-guide`)
2. What category does it belong to? (development / security / testing / etc.)
3. What triggers this skill? (When should an agent use it?)
4. What is the step-by-step workflow?
5. What are the verification criteria (Done When)?
6. Are there any anti-patterns or common mistakes to warn about?

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 a skill published in the GitHub repository drvoss/everything-copilot-cli (45 stars, last pushed 6d ago), licensed MIT. It adds 41 tokens to every session and 2,910 once invoked, about $0.0002 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 2026-08-30.
