@fractal-code/channels

Pre-built, scoped I/O adapters for the Fractal Code Void Environment. Channels are the only way data enters or exits the Wasm sandbox; the agent's logic never gets raw filesystem, network, or process access.

import { AnthropicChannel } from "@fractal-code/channels";

const claude = new AnthropicChannel("plan-llm", {
  description: "Plan-cell LLM call",
  apiKeyEnvVar: "ANTHROPIC_API_KEY",
  apiVersion: "2023-06-01",
  allowedOperations: ["createMessage"],
  allowedModels: ["claude-sonnet-4-5"],
  maxTokensPerCall: 4096,
  maxCallsPerMinute: 30,
  timeoutMs: 30000,
});

The scope is frozen at construction. Agents cannot widen it because they cannot touch channel code.

Built-in channel families (V5):

• LLM: Anthropic, OpenAI, Cohere, Google GenAI, Mistral
• Code platforms: GitHub, GitLab, GitHub Actions
• SaaS: Slack, Linear, Notion, Jira, Stripe, Sentry, Datadog, Resend
• Infra/data: Postgres, SQLite, S3, SQS, Docker, Kubernetes, Vault, Pinecone
• Tooling: Vitest/Jest/Pytest/GoTest/CargoTest, BrowserChannel, ProcessChannel, BuildChannel
• Compliance: Redactor (HMAC-SHA-256), Fairness (DP + EO metrics)
