# Managed Agent (Anthropic cloud runtime)

`ruflo-agent` has two agent runtimes behind one mental model:

| Runtime | Tools | Use it when |
|---|---|---|
| **WASM** (local, `rvagent`) | `wasm_agent_*` / `wasm_gallery_*` | fast, free, ephemeral, offline, untrusted code in a sandbox |
| **Managed** (Anthropic cloud) | `managed_agent_*` (this skill) | long-running / async work (minutes–hours), a real cloud container with pre-installed packages + network, persistent filesystem + transcript across turns |

This skill drives the **managed** runtime — Anthropic's [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview) (beta). The model: **Agent** (model + system + tools + MCP servers + skills) → **Environment** (container template) → **Session** (running instance) → **Events** (turns / tool-use / status, persisted server-side). See `docs/adr/0001-wasm-contract.md` and project ADR-115.

## Prerequisites

- `ANTHROPIC_API_KEY` (or `CLAUDE_API_KEY`) in the environment, with Claude Managed Agents beta access.
- If absent, every `managed_agent_*` tool returns a structured "use `wasm_agent_create` for a local no-key runtime" error — fall back to the WASM skill.

## Steps

1. **Create** — `mcp__claude-flow__managed_agent_create`
   `{ model?, system?, name?, networking?, packages?, initScript?, mcpServers?, skills? }`
   → `{ sessionId, agentId, environmentId, status }`. Provisions Agent + Environment + Session. Save the three ids.
   - `mcpServers`: `[{type:"url", url, name, authorization_token?}]` — the cloud agent must be able to *reach* the URL. A local `ruflo mcp start` is **not** reachable from Anthropic's cloud; deploy/tunnel an HTTP ruflo MCP server first if you want the cloud agent to have ruflo's tools.
   - `packages`: `{pip?:[], npm?:[], apt?:[], cargo?:[], gem?:[], go?:[]}` — installed in the container.

2. **Prompt** — `mcp__claude-flow__managed_agent_prompt`
   `{ sessionId, message, maxWaitMs? }` → sends a user turn, polls the event log until the session goes idle (default 180s, capped 600s) → `{ finished, status, stopReason, assistantText, toolUses[], eventCount }`. For very long tasks, raise `maxWaitMs` or follow up with `managed_agent_events`.

3. **Inspect** — `mcp__claude-flow__managed_agent_status` `{ sessionId }` (idle/running/error) · `mcp__claude-flow__managed_agent_events` `{ sessionId, raw? }` (full transcript: user turns, agent thinking, tool_use, tool_result, status — the cloud counterpart of `wasm_agent_files`).

4. **List** — `mcp__claude-flow__managed_agent_list` `{ limit? }` — every session on the org (so you can see which are still running / billing).

5. **Terminate** — `mcp__claude-flow__managed_agent_terminate` `{ sessionId, environmentId? }` — **always do this when done**: a cloud session keeps billing container time + tokens until deleted. Pass `environmentId` to also delete the environment ruflo created.

## Cost & safety

- Managed Agents bill per session (LM tokens + container time) and are rate-limited per org. Estimate before a long run; record completed sessions to the `cost-tracking` namespace.
- Treat orphaned sessions like leaked resources — `managed_agent_list` then `managed_agent_terminate` anything stale.
- Beta API (`managed-agents-2026-04-01`); `multiagent` / `define-outcomes` on the agent config are research preview.

## Quick example

```
managed_agent_create  { "model": "claude-haiku-4-5-20251001", "system": "Terse. Do exactly what is asked.", "name": "scratch" }
  → { sessionId: "sesn_…", agentId: "agent_…", environmentId: "env_…", status: "idle" }
managed_agent_prompt  { "sessionId": "sesn_…", "message": "echo hello > /tmp/x && cat /tmp/x — then stop." , "maxWaitMs": 60000 }
  → { finished: true, status: "idle", stopReason: "end_turn", assistantText: "Done.", toolUses: [{name:"bash", input:{command:"echo hello > /tmp/x && cat /tmp/x"}}] }
managed_agent_terminate { "sessionId": "sesn_…", "environmentId": "env_…" }
  → { sessionDeleted: true, environmentDeleted: true }
```
