CLI Agent Orchestrator is a tool that coordinates multiple AI coding command-line programs by running them as separate workers in isolated terminal sessions. A supervisor uses it to delegate software tasks to specialist agents in parallel or in sequence while the workers retain their normal command-line capabilities. The catalogue skills operate this orchestration workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00137 | $0.01974 |
| Opus 5 | $0.00068 | $0.00987 |
| Sonnet 5 | $0.00027 | $0.00395 |
| Haiku 4.5 | $0.00014 | $0.00197 |
Grade A, and why
cao-mcp-apps scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Turn it on
The surface is default-off. Enable and run:
export CAO_MCP_APPS_ENABLED=true
uv run cao-server # :9889 (REST + SSE /events)
uv run cao-mcp-server # registers tools/resources via the mcp_apps plugin
It is packaged as the built-in mcp_apps plugin (cao.plugins entry-point). The
plugin's on_mcp_server hook registers the ui://cao/* resources, the five app
tools, the topology widget, and advertises the io.modelcontextprotocol/ui
capability — best-effort and default-off, so nothing changes when the flag is unset.
What the operator gets
ui://cao/dashboard— fleet overview + the mutation entry point.ui://cao/agent— one terminal's status, output tail, inbox, sub-agents.ui://cao/event-stream— live governance ticker (app-only).cao://widget/topology+/widgets/topology/— build-free live event view.
All mutations flow through submit_command(kind, payload) — kinds:
send_message, assign, create_session (standard); interrupt, pause,
resume (lifecycle); shutdown_session (destructive).
For full payload schemas and scope requirements per kind, see references/submit-command-kinds.md.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cao-mcp-apps is a skill published in the GitHub repository awslabs/cli-agent-orchestrator (1,243 stars, last pushed today), licensed Apache-2.0. It adds 137 tokens to every session and 1,974 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
