Examples

Concrete extensions in real scenarios — a code-review subagent, a lint skill, a Postgres MCP server connection, and a pack that bundles them.

Each one is a single install that shows up in every coding agent you've configured.

A code-review subagent

Section titled A code-review subagent

You want a focused reviewer that checks a diff and reports back without crowding your main conversation. Install a subagent:

axm subagents install @acme/subagents/code-reviewer
axm sync

Then delegate to it from your primary agent:

Have the code-reviewer subagent check my changes before I open a PR.

The subagent reads the diff in its own context and returns only its findings.

A lint skill

Section titled A lint skill

You want your agent to apply your team's lint conventions on demand. Install a skill:

axm skills install @acme/skills/lint
axm sync

The next time you ask the agent to clean up a file, it matches the skill's description, pulls the full SKILL.md into context, and applies your rules — no extra prompting.

A Postgres MCP server connection

Section titled A Postgres MCP server connection

You want the agent to query a real database instead of guessing at the schema. The Postgres MCP server is external; what you install is the connection that lets your agent reach it:

axm mcps install @acme/mcps/postgres
axm sync

The connection references your DATABASE_URL by name, so it's safe to commit. Now the agent can inspect tables and run read-only queries while it works:

Using the postgres connection, show the columns on the orders table.

A pack bundling all three

Section titled A pack bundling all three

You want a teammate to get the whole review setup in one step. Bundle the subagent, the skill, and the connection into a pack:

{
  "owner": "@acme",
  "type": "pack",
  "name": "review-kit",
  "version": "1.0.0",
  "dependencies": {
    "@acme/subagents/code-reviewer": "^1.0.0",
    "@acme/skills/lint": "^1.0.0",
    "@acme/mcps/postgres": "^1.0.0"
  }
}

Now a single install gives the whole team the vetted, version-pinned set:

axm packs install @acme/packs/review-kit
axm sync

One command, and the code-review subagent, the lint skill, and the Postgres connection are all live across every agent they use. Uninstalling the pack cleans up the three members it brought in.
