skillport

skillport is a skill for Claude Code, Codex from eikonoikari1/skillport. It costs 111 tokens per session (1,587 once invoked), scanned A, a copy of skillport, MIT.

A tool for converting skills, rules, and configuration between AI coding environments such as Claude Code, Cursor, Codex, Copilot, and Windsurf.

In plain words
What is it for?
Use it to adapt one skill or rule, or a group of detected configurations, to another supported coding environment.
Why use it?
It removes the need to manually rewrite guidance when moving a project or workflow between coding tools.

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

skillport 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.

The scan reads SKILL.md. This mod also ships 25 executable files (bin/skillport.ts, src/adapters/dynamic-context.ts, src/adapters/globs.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

This is a copy

98% identical to skillport — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

skillport: Universal Skill/Rule Adapter

Step 1: Understand the Request

Parse the user's prompt to extract three things:

  1. WHAT — Which skill/rule/config to convert
    • A path (e.g., .claude/skills/my-skill, CLAUDE.md, .cursor/rules/)
    • A skill name (e.g., "clearshot", "toc") — resolve to its installed path
    • "all" or "everything" — scan for all detected configs
  2. FROM — Source harness format
    • Explicit: "from claude", "from cursor", etc.
    • Implicit: auto-detect from path and file contents
  3. TO — Target harness format(s)
    • Explicit: "to cursor", "to codex and openclaw", "to all"
    • One or more of: claude, cursor, codex, openclaw, copilot, windsurf, all

Examples of natural language parsing:

User says WHAT FROM TO
"convert clearshot to cursor" clearshot auto-detect cursor
"port my claude skills to codex" all claude skills claude codex
"make this cursor rule work in claude code" (ask which rule) cursor claude
"adapt toc for all harnesses" toc auto-detect all
"what harness configs do I have?" (detect mode)

Resolution Rules:

  • If WHAT is a name (not a path), search these locations:

    • ~/.claude/skills/<name>/
    • ~/.agents/skills/<name>/
    • .claude/skills/<name>/ (project-local)
    • .agents/skills/<name>/ (project-local)
    • .cursor/skills/<name>/
    • .cursor/rules/<name>.mdc
  • If FROM is not stated, auto-detect by running the CLI:

    npx tsx ~/.claude/skills/skillport/bin/skillport.ts detect .
    
  • NEVER start conversion until WHAT, FROM, and TO are all resolved.

Step 2: Confirm Before Converting

Always show the user what you're about to do:

I'll convert:
  Skill:  <name> (<path>)
  From:   <harness> (auto-detected / specified)
  To:     <target harness(es)>

Proceed?

Wait for confirmation. If the user says "just do it" or similar, proceed.

Step 3: Run the Conversion

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.
