proskill

The Canonical Manager for Agent Skill Subsets

proskill is a CLI tool designed to solve the "Skill Overload" problem for AI agent harnesses. It allows you to maintain a Canonical Library of all your skills while exposing only specific subsets via profiles.

It leverages the skills ecosystem (must be installed in your environment) to fetch and install skills directly into your local library.

1. Overview: Canonical Library vs. Profiles

• The Canonical Library (~/.agents/db/skills): The single source of truth. All your skill files or directories live here.
• Profiles: Named configurations stored as individual JSON files in ~/.agents/db/profiles/<profile-id>.json.
• The Access Layer: proskill provides a get-paths command that outputs absolute paths for skills in a profile, making it easy to integrate with any agent harness.

2. Installation

# Recommended installation via NPM
npm install -g proskill

Note: Requires the skills CLI to be available in your PATH.

3. Command Reference

proskill init

Sets up the infrastructure in ~/.agents/db/.

proskill add <source>

Fetches a skill from an external source (e.g., GitHub owner/repo, URL) and adds it to your local library.

• Example: proskill add vercel-labs/agent-skills/skills/find-skills

proskill profile create <profile-id>

Initializes a new, empty profile definition.

• Example: proskill profile create automation

proskill profile add <profile-id> <skill-id>

Adds a skill from your local library to a specific profile.

• Example: proskill profile add automation find-skills

proskill profile get-paths <profile-id>

Outputs the absolute paths of all skills defined in the chosen profile, one per line.

• Example: proskill profile get-paths automation

proskill list

Displays all available profiles and the number of skills they contain.

proskill status

Shows an overview of the library contents and current profile mappings.

4. Technical Architecture

Skill Storage & Resolution

Skills are stored in ~/.agents/db/skills. When adding a skill to a profile, proskill resolves the ID by checking for exact matches or matches with extensions in the library.

Profile Storage

Profiles are stored as individual JSON files:

// ~/.agents/db/profiles/automation.json
{
  "skills": ["find-skills"]
}

5. Example Workflow

1. Initialize the system:

   proskill init

2. Fetch a skill from the ecosystem into your library:

   proskill add vercel-labs/agent-skills/skills/find-skills

3. Create a profile and add the skill to it:

   proskill profile create my-tools
   proskill profile add my-tools find-skills

4. Get paths for your agent configuration:

   proskill profile get-paths my-tools
   # Output:
   # /Users/youruser/.agents/db/skills/find-skills
