Dispatch autonomous AI coding agents to your GitHub repos — directly from chat. Single-agent or multi-launch, create, monitor, and cancel tasks without leaving the conversation.
LeemerChat already lets you talk to your codebase via PowerCode. Blackbox Cloud takes it further: instead of just reading code, you can now tell AI agents to write code — on your actual repos, in isolated sandboxes, with real commits.
Describe what you want in plain English inside the chat. The AI translates your intent into a Blackbox task, dispatches agents, and reports back — no context switching to another platform.
Launch Claude, Codex, Gemini, and Blackbox on the same task simultaneously. Blackbox Cloud compares their diffs and recommends the best implementation automatically.
Create tasks, monitor progress, check which agent won, cancel if needed — all without leaving the conversation. Your chat history becomes a log of every change dispatched.
Bring your own Blackbox API key. The integration is fully optional — if you don't add a key, the AI has no idea these tools exist. Remove the key any time to turn it off.
Blackbox Cloud supports four agent types. In multi-launch mode, they all work on your task simultaneously and their diffs are compared automatically.
Claude Sonnet 4.5
Anthropic's flagship coding agent. Best for TypeScript, structured reasoning, and production-quality implementations.
Blackbox Pro
Blackbox's own agent optimised for rapid prototyping, boilerplate generation, and multi-file scaffolding.
GPT-5 Codex
OpenAI's code-specialised model. Strong at algorithm design, refactoring, and test generation.
Gemini 2.0 Flash
Google's multimodal agent. Excellent for documentation, code analysis, and large-context understanding.
The integration adds four tools to LeemerChat's AI assistant. These tools are only visible when you've added your Blackbox API key in Settings → API Keys. No key, no tools — the AI has zero knowledge of Blackbox otherwise.
blackbox_create_taskDispatch a coding task to one or multiple agents on any GitHub repo. Supports single-agent and multi-launch modes.
"Add rate limiting to the /api/users endpoint"
blackbox_check_taskCheck task status, progress, agent executions, diff analysis, and which agent produced the best result.
"What's the status of my Blackbox task?"
blackbox_cancel_taskStop a running task that is no longer needed or taking too long. Terminates the sandbox immediately.
"Cancel my running Blackbox task"
blackbox_list_reposBrowse your GitHub repositories connected to Blackbox to find the right repo before creating a task.
"List my GitHub repos on Blackbox"
Here's what a typical multi-agent workflow looks like, entirely inside the chat:
"Use Blackbox to add Stripe payment integration to github.com/myorg/api — use Claude, Codex, and Blackbox agents"
AI calls blackbox_create_task with agents: [{agent: 'claude'}, {agent: 'codex'}, {agent: 'blackbox'}]. Returns taskId: abc123.
"How's the task going?"
AI calls blackbox_check_task(abc123). Reports: Claude completed (branch: feature/stripe-claude), Codex at 85%, Blackbox completed. Best agent: Claude (9/10).
"Great, cancel the Codex agent — Claude's solution looks best"
AI calls blackbox_cancel_task(abc123). Task stopped. Claude's branch is ready for PR review.
Both are tools in LeemerChat. They solve different problems and work great together.

Visit cloud.blackbox.ai, click your profile image, then select "BLACKBOX API Token", then copy or generate a token starting with bb_.
Ensure your GitHub account is connected in Blackbox so agents can access your repositories.
Open Settings, then API Keys, and paste your Blackbox AI key. Once saved, the four Blackbox tools become available to the AI assistant.
Just ask in chat: "Use Blackbox to add auth middleware to github.com/myorg/api using Claude and Gemini agents". The AI handles the rest.
Your Blackbox API key is stored only in your browser's localStorage — never on our servers.
API calls to Blackbox go through our authenticated server proxy — your key never appears in browser network logs.
If you remove the key, all Blackbox tools disappear from the AI instantly.
We do not store, log, or share any data from your Blackbox tasks. Credits are charged to your Blackbox account.
Add your Blackbox API key, pick a repo, describe what you want, and let the agents handle the rest — all from inside LeemerChat.
