File contents

Contributing to agent-plugins

This repo is a plugin marketplace. Use the included CLI tool to install and manage skills.

CLI Tool

Run with dotnet scripts/plugin-cli.cs -- <command>.

Prerequisite: .NET 10 SDK (or later).

Commands

Each asset category (skills, agents, prompts, instructions, mcp, settings) supports:

Subcommand	What it does
`list`	Show what's installed vs what's in the repo
`install`	Copy from repo → installed location
`uninstall`	Remove repo-managed assets from installed location
`diff`	Compare repo vs installed — shows missing, extra, and changed files

Use all to operate across every category: all list, all install, all diff.

Common Workflows

# See what's out of sync
dotnet scripts/plugin-cli.cs -- skills diff --verbose

# Install a specific skill
dotnet scripts/plugin-cli.cs -- skills install --skill ci-analysis --force

# Install everything from the repo
dotnet scripts/plugin-cli.cs -- all install --force

# Dry-run to preview changes
dotnet scripts/plugin-cli.cs -- all install --dry-run

# Full sync: install repo assets AND remove extras not in repo
dotnet scripts/plugin-cli.cs -- all install --exact

Key Options

Option	Effect
`--skill <name>`	Filter to one skill
`--plugin <name>`	Filter to one plugin group
`--scope personal\|project`	Install to `~/.copilot/skills/` + `~/.claude/skills/` (default) or `.github/skills/`
`--force`	Overwrite without prompting
`--exact`	Full sync — removes installed files not in repo (after backup)
`--dry-run`	Preview without changes
`--verbose`	Show detailed output

💡 After editing a skill, run skills install --skill <name> --force to update your local copy.

Adding a Skill

Every new skill requires updates to 4 locations:

Step	File	Action
1	`plugins/<group>/skills/<name>/SKILL.md`	Create with `name` + `description` in YAML frontmatter
2	`plugins/<group>/plugin.json`	Add path to `"skills"` array
3	`.claude-plugin/marketplace.json`	Ensure plugin group is listed
4	`README.md`	Verify skill appears in Available Plugins
