skillify

skillify is a skill for Claude Code, Codex from 0xMH/claude-skillify. It costs 26 tokens per session (1,792 once invoked), scanned A, a copy of skillify, MIT.

A tool for turning the repeatable process from a coding session into a reusable skill for future sessions.

In plain words
What is it for?
Use it at the end of a process you want to automate or reuse. It analyzes the session and asks questions to define the resulting skill.
Why use it?
It helps preserve the steps, inputs, tools, decisions, and success criteria of a process so they do not need to be reconstructed later.

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

skillify 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 4d 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.

Skillify

You are capturing this session's repeatable process as a reusable skill.

Your Session Context

You have the full conversation history available to you. Analyze it directly to understand what process was performed, what tools were used, and how the user steered you.

If a description was provided: The user described this process as: "$description"

Your Task

Step 1: Analyze the Session

Before asking any questions, analyze the conversation history to identify:

  • What repeatable process was performed
  • What the inputs/parameters were
  • The distinct steps (in order)
  • The success artifacts/criteria (e.g. not just "writing code," but "an open PR with CI fully passing") for each step
  • Where the user corrected or steered you
  • What tools and permissions were needed
  • What agents were used
  • What the goals and success artifacts were

Step 2: Interview the User

You will use AskUserQuestion to understand what the user wants to automate. Important notes:

  • Use AskUserQuestion for ALL questions! Never ask questions via plain text.
  • For each round, iterate as much as needed until the user is happy.
  • The user always has a freeform "Other" option to type edits or feedback -- do NOT add your own "Needs tweaking" or "I'll provide edits" option. Just offer the substantive choices.

Round 1: High level confirmation

  • Suggest a name and description for the skill based on your analysis. Ask the user to confirm or rename.
  • Suggest high-level goal(s) and specific success criteria for the skill.

Round 2: More details

  • Present the high-level steps you identified as a numbered list. Tell the user you will dig into the detail in the next round.
  • If you think the skill will require arguments, suggest arguments based on what you observed. Make sure you understand what someone would need to provide.
  • If it's not clear, ask if this skill should run inline (in the current conversation) or forked (as a sub-agent with its own context). Forked is better for self-contained tasks that don't need mid-process user input; inline is better when the user wants to steer mid-process.
  • Ask where the skill should be saved. Suggest a default based on context (repo-specific workflows -> repo, cross-repo personal workflows -> user). Options:
    • This repo (.claude/skills/<name>/SKILL.md) -- for workflows specific to this project
    • Personal (~/.claude/skills/<name>/SKILL.md) -- follows you across all repos

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.
