Skild

skild

skild is the package manager for Agent Skills — like npm, but for AI agents.

When to Use

Use this skill when:

• Installing new capabilities for AI agents
• Managing installed Skills (list, update, uninstall)
• Publishing Skills to share with the community
• Searching or discovering new Skills

Agent Search & Discovery (Skild Index)

When an agent needs to find Skills from the Skild index (registry + linked + auto catalog), use the Registry API:

# Unified discovery (registry + linked skills)
curl "https://registry.skild.sh/discover?q=<query>&limit=20"

# Resolve a short alias (optional)
curl "https://registry.skild.sh/resolve?alias=<alias>"

Notes:

• Prefer alias if present; it provides the shortest install command.
• Use the returned install string directly (quotes may appear when a #ref is required).
• /discover supports pagination and filtering:
  • cursor=<nextCursor> for pagination
  • sort=updated|new|downloads_7d|downloads_30d|stars|stars_30d
  • skillset=true|false and category=<id> to narrow results
• If you need to browse linked items only:
  • https://registry.skild.sh/linked-items?limit=20
• CLI skild search uses the same unified index.

Agent Workflow (Recommended)

1. Search via /discover and shortlist results by description/tags.
2. Confirm with the user and pick the best match.
3. Install using the provided install command (or alias).
4. Manage using skild list / info / update / uninstall / sync.

Prerequisites

Node.js ≥18 is required.

npm install -g skild

Target Platforms

# Example: Install to Antigravity
skild install @publisher/skill -t antigravity

# Project-level installation
skild install @publisher/skill --local

Defaults & Scope

# Default platform & scope
skild config set defaultPlatform codex
skild config set defaultScope project

# Default repo for push
skild config set push.defaultRepo owner/repo

Skillsets

Skillsets bundle multiple Skills for one-command installation:

skild install @skild/data-analyst-pack
# Installs: csv, pandas, sql-helper...

Publishing Skills

# 1. Create account
skild signup

# 2. Login
skild login

# 3. Publish
skild publish --dir ./my-skill

Push to Git Repos (Registry-free)

Use skild push to sync a Skill into a Git repository and push changes.

# Push to GitHub by owner/repo
skild push owner/repo --dir ./my-skill

# Set a default repo (omit <repo> afterwards)
skild config set push.defaultRepo owner/repo
skild push --dir ./my-skill

# Push to a local repo path
skild push ~/work/skills-repo --local --dir ./my-skill

# Push to a specific subdirectory
skild push owner/repo --dir ./my-skill --path skills/my-skill

# Push to a branch (or append #branch to the repo)
skild push owner/repo#dev --dir ./my-skill

Notes:

• The target path defaults to skills/<skill-name> derived from SKILL.md.
• Target path cannot be the repo root.
• The command clones, commits, and pushes to the remote branch.
• For owner/repo, skild tries SSH first and falls back to HTTPS if SSH auth fails.
• skild push <repo> always overrides the default repo.
• You can also set SKILD_DEFAULT_PUSH_REPO to override the default repo per shell.
