Agents: concepts
The mental model for building agents on MyChatBot. Your workspace ships with a curated set of built-in agents, each tuned for a part of the business. You customize any of them — name, model, instructions, tools, skills — and every change is scoped to your account only. When nothing built-in fits, you claim a blank Custom Agent and build one from scratch. Read this first — every other page in this section assumes these terms.
In the app
Everything here lives under Agents in the left nav → https://app.mychatbot.app/agents. Open any agent to chat with it, configure it, or schedule runs.
Cheat sheet
| Term | What it means |
|---|---|
| Built-in agent | A ready-made agent MyChatBot ships, tuned for a job — it comes with a default model, prompt, tools, and skills. You can't rename the built-in kind, but you can fully customize your copy of it. |
| Customization | The changes you make to an agent. Only the fields you touch change; everything else stays at the built-in default. Scoped to your account and marked with a Customized badge. |
| Reset to default | One button that clears all your customizations and reverts the agent to how it ships. |
| Custom Agent | A blank-canvas agent you build from scratch. You get up to 10. |
| Director / Team | An agent that coordinates a team of specialist agents behind a single chat, instead of doing the work alone. |
Agents that ship in your workspace
Nine built-in agents come with your workspace. The first three are the core, general-purpose set; the rest are specialists (one of which, Content Director, runs a whole team).
| Agent | Default model | Built for |
|---|---|---|
| Sales Platform Assistant | GPT-5 | Sales Platform setup & configuration — the default, general-purpose agent |
| Personal Assistant | Claude Opus | General knowledge work — browsing, code, research |
| Skill Architect | Claude Opus | Designing and building your own account skills |
| Bulk Text Worker | GPT-5 mini | High-volume, low-cost text — classify, extract, normalize, tag |
| Content Factory | Claude Sonnet | Marketing media — images today (video + audio coming) |
| Site Builder | Claude Sonnet | Single-page sites published to a live *.page.mychatbot.app address |
| Content Director | Claude Sonnet | A Director that runs a Content Team: write → scale to variants → schedule → analyze |
| HR Recruiter (Work.ua) | DeepSeek | Recruiting over Work.ua + your Sales Platform CRM |
| PROM Cart Designer | DeepSeek | Enhancing PROM product photos via the Product Photo Pipeline skill |
Plus up to 10 Custom Agents you can build — they appear in your list only once you create them.
Specialists are just pre-tuned agents
Nothing about the specialists is special under the hood — each is an ordinary agent with a tuned model, prompt, tools, and skills. Two of them (HR Recruiter, PROM Cart Designer) started as one customer's Custom Agent and were promoted into the shared catalog. Everything below — customizing, resetting, pausing — works the same on all nine.
Customizing an agent
Open an agent, then go to the Settings tab (https://app.mychatbot.app/agents → pick an agent → Settings). Anything you change here layers on top of the built-in defaults and applies only to your account. Leave a field empty and it falls back to the platform default.
| In the app | What it controls | Default when left empty |
|---|---|---|
| Settings → Identity → Name / Description / Avatar | How the agent is labeled in your list | The built-in name and look |
| Settings → Identity → Model | Which model powers it | The built-in default (shown as "· default") |
| Settings → Identity → Labels | Filter pills on your agents list | none |
| Instructions tab | What it focuses on, what to avoid, how it responds — layers on top of its built-in expertise | The built-in prompt |
| Settings → What it can do | Which tools the agent can reach for (on/off toggles) | The built-in toolset |
| Settings → Connectors | Which of your connected apps it can use | The built-in connectors |
| Settings → Skills | Custom abilities attached to it | The built-in skills |
How your changes combine:
- Tool and connector toggles are independent — turning one off doesn't touch the others. Off means the agent won't see that tool at all; it answers from memory and the conversation only.
- The Instructions you write replace the built-in prompt for your copy of the agent.
- The Skills and Labels lists show exactly what's attached; you edit them directly. If you remove the built-in entries there, they're gone for your agent — so re-add any you still want.
Hit Save and a Customized badge appears on the agent.
Your changes take effect on the very next message
Customizations aren't baked in — they're read fresh on every run. Change a setting, save, and the next message already uses it. Your changes never affect other accounts running the same built-in agent.
You can also let the agent edit itself
If the Self-edit tool is on, you can just tell the agent in chat to change its own instructions, model, tools, name, or skills ("be more terse", "turn on web search"). Every self-change pauses for your approval before it sticks.
The model is a default, not a lock
Every agent ships with a default model (marked "· default" in the picker), but you can move any agent to a different model from Settings → Identity → Model. Cheaper model for a high-volume job, a frontier model for hard reasoning — it's a per-agent choice. Custom Agents also let you pick the model right when you create them.
Reset to default
The Reset to default button on the Settings tab clears every customization and reverts the agent to how it ships. If you haven't customized anything, there's nothing to reset (the button is a no-op — "running on platform defaults").
Toggles reset one at a time; lists reset as a whole
Turning one tool off leaves your other tools alone. But the Skills and Labels lists are edited as a single list — if you clear one and add a single entry, you've dropped everything the agent had by default. Include the ones you still want.
Custom Agents (build your own)
When no built-in agent fits, build one from scratch. In the app: Agents → New agent (https://app.mychatbot.app/agents/new). Pick a name, model, and description; refine tools, skills, and tasks after creation. You get up to 10 Custom Agents, and the form shows how many slots are still free.
A Custom Agent starts as a blank canvas: a generic prompt, a light default toolset, and a model you choose. Once created it appears in your agents list (nobody else sees it), and you configure it exactly like a built-in agent — same Settings tab, same toggles.
Delete vs. reset a Custom Agent
- Reset to default clears a Custom Agent's customizations but keeps it — it stays yours.
- Delete (Settings → Delete this agent) wipes it permanently — every conversation, schedule, and saved task — and returns the slot to your free pool so you can build a different one. This can't be undone.
- Out of slots? Reset or delete a Custom Agent to free one, or contact support to raise your cap.
A Custom Agent can graduate into the catalog
Two shipped specialists — HR Recruiter and PROM Cart Designer — began as a single account's Custom Agent and were promoted (same model, prompt, and skills) into the shared built-in catalog. There's no self-serve path for this; it's a manual MyChatBot decision. Build your idea on a Custom Agent, and if it proves broadly useful, it can become a built-in later.
Directors and teams
Some agents are Directors — they coordinate a team of specialist agents behind a single chat rather than doing the work alone. The shipped example is Content Director, which runs a Content Team: writing, scaling a piece into many variants, scheduling, and performance analysis.
To you, a Director behaves like one agent:
- one avatar, one chat thread;
- it routes each request to the right specialist and returns a single synthesized reply;
- replies are attributed to whichever member produced them, so you get "the team" without juggling separate chats.
In the app, open a Director and look at the Team roster — the specialists it coordinates. Tools, skills, and connectors are configured per member, not on the Director: open any member to flip its toggles, and those changes apply wherever that member is used. The Director's own instructions act as its "how to delegate" playbook.
Custom Agents can't be team members
Custom Agents are standalone by design; a Director's roster is made of built-in specialists only.
Best practices
Do
- Start from the built-in agent whose model and defaults already fit the job — a specialist (Content Factory, Site Builder, Bulk Text Worker…) before a general-purpose one — and customize only what you must.
- Keep customizations light — a small set of changes is easier to reason about and survives future updates to the built-in defaults.
- To move an agent onto a specific or cheaper model, just change it in Settings → Identity → Model — no need to create a Custom Agent for that.
- When editing the Skills or Labels list, re-add everything you want to keep.
Don't
- Don't clear the Skills list down to one skill and assume the built-in ones are still attached — the list is what's attached.
- Don't build a Custom Agent just to switch models — the model picker is on every agent's Settings tab.
- Don't try to delete a built-in agent. To stop using one, pause it (Settings → Pause this agent) — that hides it and blocks new conversations while keeping existing ones readable. Only Custom Agents can be deleted.
Test it
- Open an agent and make a change on the Settings or Instructions tab (change the instructions, or toggle a tool on). Save, and confirm the Customized badge appears.
- Send a message and verify the new behavior — the extra tool is available, or the new prompt voice shows up.
- Click Reset to default and confirm every field reverts to how the agent ships and the Customized badge clears.
- For a Custom Agent: create one with a specific model, run it once, and confirm the reply comes from the model you picked.
- Change Settings → Identity → Model on a built-in agent, run once, and confirm the run is served by the new model — the model is a default you can move, not a lock.
