In plain words
What is it for?
Use it to create a SKILL.md file, document an AI workflow, or contribute a new skill to the affiliate-skills repository.
Why use it?
It removes the need to rewrite or explain the same workflow each time. It also packages the process so other people can install and reuse it.

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 6d 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 — 437 lines — stays where its author put it; the contents beside it link to each section on GitHub.

List Affitor Skill

Turn a repeatable AI prompt or workflow into a structured, shareable skill for the affiliate-skills GitHub repository. The output is a complete SKILL.md file that works in any AI agent — shared via npx skills add Affitor/affiliate-skills so anyone can install it.

Stage

This skill belongs to Stage S8: Meta

When to Use

  • User has a prompt they keep reusing and wants to turn it into a shareable skill
  • User wants to create a new skill for the affiliate-skills repository
  • User wants to write a SKILL.md file in the standard format
  • User says "make this a skill" or "write a skill for X"
  • User wants to package an AI workflow so others can replicate it

Input Schema

{
  raw_prompt: string       # (required) The prompt, workflow description, or detailed explanation of what the skill does
  failure_modes: string    # (optional) What goes wrong when the output is bad — helps write better Instructions and Error Handling
  niche: string            # (optional) Category hint, e.g., "content", "research", "seo"
  examples: string         # (optional) Example input/output pairs the user already has
}

Workflow

Step 1: Understand What the Prompt Actually Does

Before writing anything, analyze the user's raw prompt or workflow description:

  1. Task type — Is this content creation, research, analysis, planning, automation, or something else?
  2. Variable inputs — What changes each time? (product name, URL, audience, topic, etc.)
  3. Fixed structure — What stays the same? (output format, sections, tone, constraints)
  4. Quality differentiator — What makes a good output vs. a bad one?
  5. Failure modes — Where does the AI tend to go wrong without explicit guidance?

If the user gave a vague description instead of an actual prompt, ask:

  • "What do you typically paste into ChatGPT/Claude for this?"
  • "What does the output look like when it works well?"
  • "What goes wrong when it doesn't?"

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.
