Fusion’s command-line interface is exposed through the fn command.

Global Usage

Global options

Option	Description

Project resolution order

When --project is not supplied, Fusion resolves project context in this order:

1. Explicit --project flag
2. Default project (set via fn project set-default <name>)
3. Current-directory auto-detection (.fusion/fusion.db lookup upward)

Subcommands: stop, start, mailbox, import, export.

fn agent import

Import agents from companies.sh packages. Supports single manifest files, team packages, and archives.

Source formats:

• Single AGENTS.md manifest file
• Companies.sh package directory with COMPANY.md, TEAM.md, and AGENTS.md
• Archive files (.tar.gz, .tgz, .zip)

Options:

Option	Description
--dry-run	Preview import without creating agents
--skip-existing	Skip agents with names that already exist in Fusion

Team hierarchy: When importing a companies.sh package with team structure, the importer preserves manager/report relationships for both fresh and partial imports. Manifest-style manager references such as ceo, ../ceo/AGENTS.md, and already-valid Fusion agent IDs are resolved to actual Fusion reportsTo agent IDs before agents are created, and --skip-existing reuses matching existing managers when available instead of flattening the org tree.

Examples:

# Import a single agent manifest
fn agent import ./ceo/AGENTS.md

# Import a full companies.sh package
fn agent import ./my-company/

# Import from archive
fn agent import ./package.tar.gz

# Preview without creating
fn agent import ./package/ --dry-run

# Skip existing agents
fn agent import ./package/ --skip-existing
