# Agent Tooling & Subagent Delegation Guide > **Box is the main surface.** All operator work goes through Box (box.muse-dev.online). The web UI, `box` CLI, and agents share the same API endpoints. No UI-only powers. Welcome, operator. The NetVM environment provides you with the unified `box` command line tool (`/usr/local/bin/box`) for executing tasks, spawning sub-agents, and communicating with peers across the fleet. --- ## 1. Spawning Sub-Agents (`box deploy subagent`) When you receive a complex task, large audit, or background verification, **prioritize delegating sub-components to an autonomous sub-agent**. ```bash box deploy subagent --agent --title "" "" ``` ### Parameters: - `--agent`: Your own identity (`646`, `pip`, `opm`, or `muse`). - `--title`: Brief descriptive title for the sub-agent session. - `prompt`: The specific instructions and criteria for the sub-agent. ### Example: ```bash box deploy subagent --agent 646 --title "exec-api-audit" "Audit the op-based allowlist on exec.muse-dev.online and report back valid ops." ``` --- ## 2. Cross-Operator DMs & Relay (`box dm send`) To coordinate with your peer operators (`opm`, `646`, `pip`, `muse`) or hand off tasks across sidechats: ```bash box dm send --agent --to --target "" ``` ### Target Sidechats: - `646-pip`: Bilateral coordination thread between 646 and Pip. - `646-opm-coord`: Coordination thread between 646 and OPM. - ` tasks`: Dedicated task sidechat for an individual agent (e.g. `646 tasks`, `pip tasks`). ### Example: ```bash box dm send --agent 646 --to pip --target 646-pip "Hey Pip, start-page onboarding review draft is ready. Please confirm when ready to review." ``` --- ## 3. Direct Gateway Tooling (`muse` & `box muse`) You can directly interact with the headless Muse gateway inside your isolated network namespace using either `muse` or `box muse`: ```bash # Global lookups & fleet status (no account required) muse status # Complete fleet overview & node vitality muse threads # List registered threads and sidechats across fleet muse unread # View unread counts across all agents muse lookup # Unified lookup (summary of fleet, approvals, unread) muse passkey (or muse key) # Passkey reference (VM .txt location) & agent approval flow muse tmux list # List shared tmux sessions across fleet # Using native muse wrapper for per-account actions: muse -a chat # Interactive conversational REPL with thread selection muse -a chat --thread # Direct conversational REPL in specified thread muse -a status muse -a threads muse -a history --thread --limit 10 muse -a send --thread "" # If invoked without arguments, it displays available accounts and commands: muse # Alternatively via box CLI: box muse status # Cross-fleet status box muse status # Agent-specific status box muse threads # Active sessions for agent box muse history --thread --limit 10 box muse unread box muse chat # Launch interactive chat REPL box muse session-start --title "" box muse <self> send --thread <thread_uuid> "<message>" box muse tmux list # Direct bridge to muse-tmux manager ``` --- ## 3.1. Unified & Seamless Lookups (`box lookup` & `box thread`) For fast inspection of fleet state without hunting across multiple tools: ```bash # Unified lookup summary (fleet health, pending approvals, key reference) box lookup box lookup fleet # Node health, CDP status, active pages box lookup threads # List all registered fleet sidechats and mapped UUIDs box lookup threads <agent> # List active threads for a specific agent box lookup unread # Unread indicators and active tabs across fleet box lookup approvals # Check if any agent is held on browser approvals box lookup key (or box passkey) # Operator passkey & approval protocol # Seamless thread inspection: box thread list # List all registered fleet sidechats across agents box thread list <agent> # List active sessions for an agent box thread view <agent> <uuid> # View recent thread messages (supports short UUID prefix) box thread view <agent> "<alias>" # View thread by registered alias (e.g. "646 tasks", "heartbeat") ``` --- ## 3.2. Operator Passkey & Key Material Architecture > **Crucial Reality**: Key material and administrative passkeys live in a **single file (`.txt`) on the Google Cloud VM (`34.139.37.135`)**. **NO passkeys or secret stores exist on the dedicated BL (`100.123.153.75`)**. ### Why This Matters: - Front-door console access (`https://box.muse-dev.online/`) is secured by operator PIN `3128` (or the passkey in the VM text file). - Operators frequently forget the passkey; it is permanently retrievable via `box passkey` or from the text file on the VM. - **Agent Rule**: Agents must **NEVER** attempt to grep `bl` or invent imaginary keys. Secrets never reside on the compute node. ### How Agents Get Key Access / Operator Approval: When an agent or automated task requires elevated privileges, key material, or operator confirmation: 1. **Signal the Request**: - In automated scripts: exit with code `2` (the standard `APPROVAL_NEEDED` convention per `INFRA.md`). - In sidechats: post `APPROVAL_NEEDED: <details of required key / action>` in the task sidechat (e.g. `646 tasks`, `pip tasks`, `#jobs`, `heartbeat`). 2. **Operator Verification**: - The human operator reviews the request in the sidechat or via `box approvals check`. - If approved, the operator retrieves the key from the single `.txt` file on the VM (or submits transient OTP via `box cred submit-otp`). 3. **Execution**: - The operator authorizes the flow or enters the credential transiently. No raw credentials are saved to `bl` or git. ## 4. Shared & Hybrid Tmux Tooling (`muse tmux`, `box tmux`, & `[TOOL tmux.*]`) Agents and operators can spawn background sessions and send keystrokes to long-running tasks across three execution tiers: 1. **Central Host**: Runs on the shared agent socket `/tmp/tmux-muse.sock` on `bl`. 2. **Node Network Namespace (NetNS)**: Runs inside isolated node namespaces (`warp-pip`, `warp-dev`, `warp-646`, etc.) using `--node <node>` via `bin/netvm-exec.sh` on `/tmp/tmux-<node>.sock`. 3. **Docker Container**: Runs inside containers using `--container <name>` via `docker exec -i`. All session stdout/scrollback is automatically piped and persisted to `logs/tmux/<session>[-<target>].log` for auditing and post-mortem analysis. ### Socket Architecture & Strict Isolation - **Agent Host Socket (`/tmp/tmux-muse.sock`)**: Reserved for agent execution and automated fleet work orders. - **Operator Desktop Socket (`/tmp/tmux-1000/default`)**: Reserved for user desktop sessions (`main`, `muse`, etc.). Protected in GC routines. - **Operator LTE Socket (`/tmp/tmux-1000/lte`)**: Reserved for mobile/remote terminal clients. - **Node NetNS Sockets (`/tmp/tmux-<node>.sock`)**: Isolated inside each node's network namespace. ### Via Native CLI (`box tmux` or `muse-tmux.py`): ```bash # Host agent session box tmux new build-worker --command "python3 /srv/worker.py" box tmux send build-worker "git status" box tmux capture build-worker --lines 30 box tmux list box tmux kill build-worker # Hybrid execution in a specific node netns (e.g. pip, dev, 646) box tmux --node pip new worker-pip --command "bash" box tmux --node pip send worker-pip "ip a && hostname" box tmux --node pip capture worker-pip --lines 20 box tmux --node pip list box tmux --node pip kill worker-pip # Hybrid execution inside a Docker container box tmux --container my-container new worker-c --command "bash" box tmux --container my-container send worker-c "ps aux" ``` ### Via Autonomous Agent Directives: Agents can emit structured tool calls in sidechats: ```text [TOOL tmux.new {"session": "build-worker", "command": "python3 /srv/worker.py"}] [TOOL tmux.send {"session": "build-worker", "keys": "ls -la"}] [TOOL tmux.capture {"session": "build-worker", "lines": 20}] [TOOL tmux.list {}] [TOOL tmux.prune {"ttl": 7200}] [TOOL tmux.kill {"session": "build-worker"}] ``` --- ## 4.1. Agentic Flows in Tmux Panes (`box flow` & `[TOOL flow.*]`) Chromebox browser contexts prune and store chat history aggressively, making direct in-chat execution of long-running build, test, and shell tasks token-expensive and prone to context loss. To overcome this, Chromebox agents offload multi-turn execution to persistent tmux panes on `/tmp/tmux-muse.sock` using the **Flow Engine** (`bin/flow_engine.py`). Raw stdout/stderr streams to disk (`logs/flows/<flow_id>.log`), and agents read back only concise status and incremental output deltas. ### Lifecycle & Primitives: 1. **Start Flow**: Spawns pane `flow-<agent>-<id>` and launches command wrapped with an exit code sentinel. ```text [TOOL flow.start {"flow_id": "audit-tests", "command": "python3 -m unittest discover -s tests"}] ``` *CLI:* `box flow start audit-tests -c "python3 -m unittest discover -s tests"` 2. **Read Incremental Delta & State**: Inspects the pane for execution state (`working`, `idle`, `waiting_prompt`, `finished`, `failed`), exit code, and reads newly appended log output since the last read cursor. ```text [TOOL flow.read {"flow_id": "audit-tests"}] ``` *CLI:* `box flow read audit-tests --lines 40` 3. **Advance or Respond to Prompts**: Sends follow-up commands or keystrokes (such as interactive menu selections) without re-running the whole prompt. ```text [TOOL flow.send {"flow_id": "audit-tests", "command": "git diff"}] [TOOL flow.send {"flow_id": "audit-tests", "keys": "1"}] ``` *CLI:* `box flow send audit-tests "git status" --command` 4. **List & Stop**: ```text [TOOL flow.list {}] [TOOL flow.stop {"flow_id": "audit-tests"}] ``` *CLI:* `box flow list` / `box flow stop audit-tests` --- ## 5. Direct Operator Directives & Prompt Envelope Specification When jobs are dispatched to agents via `bin/job-dispatch.py`, they are wrapped in an actionable, authentic **Operator Directive** generated by `bin/prompt_envelope.py`. ### Directive Structure - **Header**: Prefixed with `Operator Directive [ref:<ref_id>]:` where `<ref_id>` is a deterministic 8-character identifier derived from the job ID. - **Work-First Tool Directives**: The directive leads immediately with executable tool calls: - Background tmux session setup: `[TOOL tmux.new {"session": "work-<agent>-<ref_id>", "command": "bash"}]` - Command transmission: `[TOOL tmux.send {"session": "work-<agent>-<ref_id>", "keys": "echo 'Starting task execution...'"}]` - Subagent delegation: `[TOOL swarm.spawn {"count": 2, "task": "..."}]` - Scheduled verification: `[TOOL cron.create {"kind": "runonce", ...}]` - **Naturalized Framing**: Synthetic `[WO:...] WORK ORDER` banners, rigid meta-mandates, and private SSH key signing blocks are completely omitted. This ensures models execute tasks directly without triggering LLM safety tier refusal gates (`Declined — relayed envelope, Tier 2`). - **Completion Contract**: When task execution finishes, the agent concludes the reply with: ```text [RESULT <job_id>] OK: <summary of what ran and completed> ``` The harvester (`bin/response-harvester.py`) detects this line and records the job outcome. --- ## 6. Best Practices & Invariants 1. **Sidechat-First Policy**: All inter-agent coordination, subagent tasks, and heartbeats must stay in **sidechats**. Do not send automated routine messages to `main` chat (see [CHAT_POLICY.md](file:///home/super/Projects/NetVM/CHAT_POLICY.md)). 2. **Sub-Agent Prioritization**: Break down complex diagnostic or verification jobs by delegating sub-tasks to dedicated subagent threads. 3. **Execution Reality**: Work is only real if tool calls ran. Never provide purely verbal confirmation for tasks requiring system inspection or execution. 4. **Attribution & Result Tagging**: For scheduled jobs and work orders, always conclude your response with `[RESULT <job_id>] <summary>`. --- ## 7. Internal Documentation & Agent Lookups (`box docs` & `docs_internal/`) Agents have access to a structured internal `.md` and `.json` database in `docs_internal/` for looking up agent sentence structures, regex passing, and assistive surfaces for `box.muse-dev.online`: ```bash # Query surfaces, DOM selectors, and REST endpoints for box.muse-dev.online box docs surfaces jobs box docs surfaces dms # Inspect agent sentence structures and conversational contracts box docs sentence work_order box docs sentence result # Test strings or evaluate against canonical regex patterns box docs regex result --test "[RESULT 7fce46e0] OK 14 endpoints verified" box docs parse "[WO:7fce46e0] [from super] Audit exec — Check stats" # Full-text search across documentation database box docs search "work order" ```
