external-skill-indexlisted

A verified index of every public finance Agent Skill repository — 139 repos, 4,851 SKILL.md files — so you can find what already exists instead of rebuilding it, and avoid the third that is legally unusable. TRIGGER - looking for an existing skill, plugin or marketplace for anything financial; "is there already a skill for X"; choosing between competing finance skill packs; before writing a new finance skill; checking whether a skill repo's licence permits use; or asked what the Claude/agent finance skill ecosystem contains. Also load before recommending any third-party finance skill repository, because 44 of the 139 declare no usable licence and 12 advertise skills while shipping none.

# External finance skill index Every field below came from a live `gh api repos/<o>/<r>` call on 2026-09-04. Skill counts are literal `SKILL.md` matches in each repo's git tree, not README claims. The machine-readable catalog is **`../../../../catalog/external-skills.json`** (139 rows) — grep it rather than guessing: ```bash python -c "import json;d=json.load(open('catalog/external-skills.json',encoding='utf-8'));\ print('\n'.join(f\"{r['full_name']:<45}{r['stars']:>6}★ {r['license'] or 'NONE':<12}{r['skill_count']:>4} skills\" \ for r in d['repos'] if 'backtesting' in r['tags']))" ``` ## 1. The size of the ecosystem | | | |---|---| | Repositories indexed | **139** | | Raw `SKILL.md` files | **4,851** | | After removing mirrors and vendored copies | **4,556** | | Finance-dominant | **3,127** — the fairest single number | ⚠️ **Volume is not depth.** `quantskills` alone is 230 repos and 1,094 skills, but **803 of those (73%) sit in three auto-generated factor repos.** ## 2. 🚨 A third of it is legally unusable | Licence | Repos | |---|---| | MIT | 76 | | Apache-2.0 | 14 | | MIT-0 | 1 | | **🚨 NONE** | **33** | | **🚨 NOASSERTION** | **11** | | GPL-3.0 | 2 (+ the `quantskills` org, 192 of 230) | | AGPL-3.0 | 1 | | archived | 2 | **91 safe (65%) · 44 legally unusable (32%).** No licence is **more restrictive than GPL** — under Berne it means all rights reserved, so you may not copy, adapt or redistribute it at all. 🚨 **And it hits exactly the repos you would reach for f
