Module · Crew

Build the building blocks once.
Use them everywhere.

Crew is your team's library of Agents, Models, Skills, Tools, and Environments. Five sibling registries that turn one-off prompts into governed, reusable objects.

Agents

Defined once

System prompt, tool list, model, max rounds. Drop into any Workflow or Assistant chat.

→ pr-reviewer · sonnet · 12 rounds
→ support-triage · sonnet · 8 rounds
→ release-notes · haiku · 16 rounds
→ vendor-review · opus · 24 rounds
Models

Provider-agnostic

Anthropic. OpenAI. Gemini. Plus any OpenAI-compatible endpoint via baseUrl — your vLLM, your Bedrock, your gateway.

→ claude-sonnet-4.5 (anthropic)
→ gpt-4o (openai)
→ gemini-2.0-pro (google)
→ qwen3-32b (vllm @ 10.0.0.4)
Skills

Inline or bundled

Single Markdown files for inline skills. Multi-file ZIPs with executables for bundled skills — materialized into the sandbox at runtime.

Tools

Reusable definitions

Wrap an integration. Wrap a custom function. Hosted-key tools mean Actana provides the API key for you.

Environments

dev · staging · prod

Different sandbox configs, env vars, and secrets per environment. Same agent definitions across all.

Why this matters

Most platforms scatter prompts across files and shared docs. Crew makes the building blocks governed objects: versioned, audited, owned.
