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

creating-skills 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 13d 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.

Creating Copilot Skills

Use this skill when reusable know-how deserves a home of its own instead of living in prompts or chat history. It helps create skills that are discoverable, concise, and bundled with the right supporting assets.

When to Use

Use this skill when the user asks for things like:

  • "create a new Copilot skill"
  • "package this workflow as a reusable skill"
  • "turn our team process into a SKILL.md"
  • "add templates and examples to a skill folder"
  • "fix a skill that is too long, vague, or hard to trigger"

Typical scenarios:

  • creating a brand-new skill folder
  • refactoring a bloated SKILL.md into a leaner body plus resource files
  • improving discovery quality through better naming and descriptions
  • preparing a public-ready skill with templates, examples, and a validation checklist

Outcome Standard

A strong skill contribution usually includes:

  • a name that clearly describes the activity the skill supports
  • a description that explains both what the skill does and when to use it
  • a SKILL.md body that teaches a workflow, not a persona
  • supporting resources that are loaded on demand instead of bloating the main file
  • a clear definition of done so the agent knows when to stop

Skill Design Rules

  • Activity, not topic - name the skill after the task it performs, not the subject area alone.
  • Trigger-friendly descriptions - include realistic user phrases and contexts.
  • Progressive disclosure - keep the skill body focused; move templates, examples, and detailed checklists into resources/.
  • One coherent capability - avoid turning one skill into a junk drawer of unrelated workflows.
  • Workflow first - the main body should help the agent execute the task step by step.

Workflow

Phase 0: Frame the capability

Clarify or infer:

  • the exact task the skill should help perform
  • the signals that should trigger the skill
  • the expected output or artifact bundle
  • what makes the skill distinct from nearby skills in the repository

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
