The five default agents work out of the box. Customization lets you change how they talk (tone, rules, language) and what they can reach (connections). When the defaults aren’t enough, you can build your own agent. Open Agents to start. The left panel groups agents into Core Team (the five defaults) and Custom (your own). Click any agent to open its settings dialog — two tabs (Identity, Connections). Personality (Instructions, Language, Learning mode) lives at the bottom of the Identity tab.Documentation Index

Customizing agents requires workspace admin permissions. Members can chat with agents but can’t edit them.
What You Can Change
| Field | Default agents (Alex, Oliver, Tony, Kai, Anna) | Custom agents |
|---|---|---|
| @mention | Locked | Set once on creation, can’t change later |
| Name, Role, Goal | Locked | Editable |
| Instructions, Language, Learning mode | Editable | Editable |
| Connections | Attach / detach (Anna is read-only — inherits from the others) | Attach / detach |
| Active state | Auto — off when no connections (Anna is always on) | Manual |
Plan Tiers
Editing default agents works on every plan. Only the number of custom agents changes.| Plan | Custom agents |

Create a Custom Agent
Need an agent for something the defaults don’t cover — a billing analyst, an on-call summarizer, a documentation specialist? Build your own. Click the + next to Custom on the Agents page, then pick how to create it.- Create with AI
- Create manually
Best when you know what the agent should do but don’t want to fill every field yourself.Describe what you want in one sentence — Anna takes it from there. She typically confirms:
- Name and @mention — suggests options based on your description.
- Role and Goal — drafts both for you to approve or tweak.
- Model Tier — recommends Light / Pro / Ultra based on task complexity.
- Instructions — generates a first draft you can refine.
- Connections — asks which to attach (cloud, database, K8s, MCP).
- Learning mode — Auto or Offer.
Edit a Default Agent
Change tone, rules, language, and more. The agent’s identity (name, @mention, role, goal) stays the same — only how it speaks and behaves changes.Open the agent
Go to Agents and click an agent in Core Team. The dialog opens on the Identity tab.
Edit the unlocked fields
On the Identity tab, Name, Role, and Goal are locked with a “Set by CloudThinker, can’t be changed” hint; @mention shows “Set once, can’t be changed later”. Scroll down on the same tab to edit:
- Instructions — one textarea for house rules, hard limits, tone, and response format. Write them as plain sentences (e.g. “Reply in terse bullet points. Never propose changes that need write access. Escalate anomalies over $500.”).
- Language — reply language.
- Learning mode — Auto saves new skills automatically; Offer asks before saving.

Attach Connections
Connections are how an agent reaches your cloud, databases, Kubernetes, or MCP servers. Alex, Oliver, Tony, and Kai start with no connections — you decide what each can touch.Open the Connections tab
From the agent dialog, click Connections. The header shows the count (e.g. “3 connections”).
Pick Builtin or MCP
Use the sub-tabs to switch between Builtin (cloud, database, Kubernetes) and MCP.
A default agent with no connections is automatically off. Attach at least one to turn it back on.
Examples
| What you want | What to do |
|---|---|
| Tony replies in Vietnamese with strict SQL formatting | Set Language to Vietnamese; add a line in Instructions: “Format SQL with uppercase keywords and one clause per line.” |
| Oliver only recommends, never changes | Add to Instructions: “Recommend only — never propose changes that need write access.” |
| Alex reports cost in EUR with weekly digests | Add to Instructions: “Report cost in EUR. Summarize spend weekly.” Attach a cloud connection. |
Things to Know
- Edits apply on the next message — in-flight chats finish under the old settings.
- Pick a custom agent’s @mention carefully — it’s set once and you’ll be living with it.
