Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00111 | $0.01587 |
| Opus 5 | $0.00056 | $0.00794 |
| Sonnet 5 | $0.00022 | $0.00317 |
| Haiku 4.5 | $0.00011 | $0.00159 |
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.
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:
- 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
- A path (e.g.,
- FROM — Source harness format
- Explicit: "from claude", "from cursor", etc.
- Implicit: auto-detect from path and file contents
- 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 ships with it
28 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.
- 4d ago First seen · 159 lines · 111 tokens per session scan A 77ca9a62fe0b
skillport is a skill published in the GitHub repository eikonoikari1/skillport (1 stars, last pushed 5mo ago), licensed MIT. It adds 111 tokens to every session and 1,587 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to skillport, differing in 3 lines, and is treated as a copy.
