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 | $0.00063 | $0.01148 |
| Opus 5.5 | $0.00025 | $0.00459 |
| Sonnet 5.5 | $0.00013 | $0.00230 |
| Haiku 4.5 | $0.00006 | $0.00115 |
Grade A, and why
cao-learning scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CAO Self-Learning
CAO workflows can improve as they repeat: outcomes you report feed a retrospector agent that distills durable lessons into memory, and those lessons reach future sessions automatically. Your job depends on your role.
All of this is opt-in infrastructure. If report_outcome or a memory tool
returns disabled: true, skip it silently and continue your task — learning
is off for this run (often deliberately, e.g. a control run) and that is
expected, not an error.
A bare error with no disabled key is different: say so, don't skip it.
That shape means the tool could not reach a verdict — cao-server is unreachable,
or its settings.json could not be read — so learning may well be ON while
nothing is being recorded. Mention it in your response and carry on with the
task.
If you are a SUPERVISOR
Report an outcome after each meaningful unit of work
One report_outcome call per completed step, delegated task, or work item —
after validation/review, not before:
report_outcome(
task_label="convert package CustomerETL (iteration 2)",
success=false,
workflow_name="ssis-migration",
agent_profile="transformer", # who did the work (defaults to you)
score=40, # optional 0-100 metric if you have one
friction_notes="Lookup with partial cache emitted an invalid join; "
"improver patched the cache-mode mapping."
)
Rules for friction_notes:
- 1–3 sentences, conclusions only — the root cause, not the story.
- NEVER paste transcripts, logs, stack traces, file contents, or secrets.
- Empty string on a clean pass is fine; the success flag already carries signal.
Report failures faithfully — failed iterations are the most valuable learning signal. Do not skip reporting because a step went badly.
Dispatch the retrospector at natural boundaries
After each completed work item (a package, a feature, a review cycle) — not
after every step — hand off to the retrospector agent:
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-learning is a skill published in the GitHub repository awslabs/cli-agent-orchestrator (1,456 stars, last pushed today), licensed Apache-2.0. It adds 63 tokens to every session and 1,148 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
