# About ProSkills

ProSkills (proskills.dev) is a curated library of security-scanned, in-depth agent skills for Claude Code, Cursor, Codex and Gemini CLI.

## What is in the library

67 skills in 13 collections. 13 are free. Each skill is a folder with a SKILL.md, the files it reads, and a `profile.md` with your brand, stack or conventions, filled in on the skill's page before you download it. Skill updates never overwrite your profile.md.

## How every skill is made and checked

| Step | What happens |
| --- | --- |
| Written as a full procedure | Each skill is a complete workflow for one job, not a short list of rules. Longer detail goes in reference files the agent opens only when needed. |
| Read through | Each skill is read in full before it is added to the catalog. |
| Scanned | The open ProSkills scanner scores it 0 to 100: four pillars of 25 points for spec, efficiency, clarity and security, from over 40 rules. Any critical security finding makes the grade F. Every skill in the catalog scores 100 today. 67 of 67 are grade A. |
| Text, not remote code | Skills are Markdown. Two video skills also ship a local helper script, which is read and scanned like the rest. No skill pulls its instructions from a URL at run time or pipes a download into a shell. |
| Portable | Frontmatter uses only fields from the open spec, so the same folder works in every supported agent. |
| Versioned | Skills carry a changelog. npx proskills-cli update replaces outdated ones and leaves profile.md alone. |

Each skill page shows its score, the tokens it loads when it triggers and its file count. A scanner catches known patterns but cannot prove a skill is safe, which is why each skill is also read. Scan any skill yourself with the [Skill Scanner](https://proskills.dev/scan); the method is in [is this skill safe?](https://proskills.dev/is-this-skill-safe)

## Pricing

| Single skills | $7 to $12 | One skill, personalised, yours to keep. One-time payment. |
| Collection bundles | $14 to $39 | Every paid skill in one collection, for less than buying them one by one. |
| Library pass | $111 first year, then $88 a year | Every collection, plus new skills while the pass is active. What you paid for skills or bundles in the last 12 months comes off the first year. |
| Team pass | $399 a year | The whole library for up to 10 people, licensed for shared and company repos. |

## Open source

| Part | Where | What it does |

| --- | --- | --- |
| llms.txt | [https://proskills.dev/llms.txt](https://proskills.dev/llms.txt) | A map of the site for language models, with every skill and guide. |
| MCP server | `https://proskills.dev/mcp` | Search the catalog, read free skills and get install commands from inside an agent. |
| Discovery index | [/.well-known/agent-skills/index.json](https://proskills.dev/.well-known/agent-skills/index.json) | Lists the free skills, so npx skills add https://proskills.dev can install them. |
| Catalog JSON | [/api/catalog](https://proskills.dev/api/catalog) | Every skill with price, scan score and version. |
