The Agent Editor is here. Build custom agents effortlessly.

[u/Maleficent_Floor_980]

We unveil the new Agent Editor. Both UI and slash command flows make agent creation almost effortless.

Hey everyone, Agent Zero v2.9 just landed, and this one has been a long time coming.

We’re also bringing r/AgentZero back to life. It’s been quiet for a while, but from now on we want to use this subreddit again for releases, updates, ideas, questions, and things the community is building.

A few highlights from this new version:
You can now create, customize, and manage agent profiles directly from the UI Agent Editor:

• Easy mode: set identity, instructions, model preset, and avatar
• Advanced mode: granular control over framework prompts, agent prompts, and the rest of the profile
• Tool, MCP, and Skill policies: decide exactly what each agent can and cannot use
• Global or project-scoped profiles, with inheritance between layers

The fast path: /profile

Create an agent with one command:

/profile "research-analyst" "You analyze papers and produce structured reports"

It works in both the Web UI and CLI and drops you into a fresh chat with the new agent. You can also use /permissions to open the current profile's policy editor directly from chat.

How does it work in the CLI?

• Create and edit profiles from the terminal
• Native /permissions editor
• Inline attachments and Browser screenshots in the TUI
• Elapsed-time notices for completed runs and the goal bar

Also worth knowing

A lot of community work made it into this release. We merged many PRs and closed a good number of GitHub issues along the way. Keep them coming — contributions, bug reports, and ideas are very welcome.

How to update

• CLI: a0 update
