Install a specialist. Make it yours.

An agent is a persona, a set of instructions and a choice of tools. Since 2.2, you can share that setup as a package: find one in the Marketplace, inspect it, install it, and adapt it to your own work.

1 / 4

Simplified recreation of the Dashboard review and update flow. Example package; no installation takes place.

ABefore it acts

The whole persona, before the first turn.

Skills, plugins, and now agents: Browse the Marketplace's agent packages or import a .sophon-agent file. A package contains a manifest and persona files, with requirements for skills and tools. It does not contain executable code.
Read before confirming: The install preview shows the publisher, every persona file, injection-scan findings, required skills, expected tools, initial settings and the proposed agent id. Installing needs ManageSkills permission.
Chat can ask; you decide: Sophon can search for a specialist and request its installation. That High-risk approval is never automatic. Open the full preview and approve in the Dashboard; the CLI, Mobile and external chat channels can reject that chat request, but cannot approve it.
Autonomy is your choice: Install creates the agent with heartbeat, auto-approval, planning and model pins off. Installing a persona does not switch on its background work.

BAfter you make it yours

Your edits have a place in the update.

Review a three-way diff: An edited agent is customized, and automatic updates pause. Compare the published copy, your changes and the proposed version; choose what to apply or skip the version.
A visible origin: The agent's Marketplace panel keeps its source, installed version and update status. You can reset files to the published copy or detach from updates; detaching does not make the agent a trusted local persona.
Withdrawn versions stop: If a check finds the installed version revoked or the package removed, delegation and its heartbeat stop. You receive a security notification and choose whether to keep using that version or take another one.

CFor authors

Share the setup that works for you.

Export an existing agent, or scaffold a package project with the CLI. Review persona files for private information before exporting or publishing. A linked Marketplace account needs publishing permission; an API key is also supported by the developer CLI.

sophon agents search research --limit 10
sophon agents export researcher --output ./dist
sophon dev new agent acme-helper --author "Acme"
sophon dev validate
sophon dev build

Run validate and build from the new project directory. Legacy agent.json projects still validate and install with a warning, but must migrate to manifest.json before building or publishing. Follow the package and migration guide.

Limits

What an agent package doesn't promise.

A scan finding nothing is not a guarantee. Read the persona and install only from sources you trust; packages are not cryptographically signed.
Where it says so
Package agents stay third-party, even after you edit or detach them. Their turns do not qualify for standing auto-approval, and the router does not pick them automatically.
Where it says so
Update all skips agents. Customized agents wait for your review, and automatic updates require both your settings and a clean update gate.
Where it says so
Publishing through Sophon requires a Marketplace with agent publishing support and a fresh account link with publishing allowed. DevStudio agent projects need version 1.1.0 or later; its distribution remains separate.
Where it says so

Start with a persona you can read.

Review an agent in the Dashboard, or package your own with the CLI.
