embed-pi-cli

A guide for embedding the pi command-line agent into another command-line project. It covers shared configuration, custom extensions, running pi as a separate process, and connecting outside messaging channels.

In plain words
What is it for?
It is for distributing pi settings, publishing project-specific extensions, running pi from CI or pipelines, and adapting channels such as Telegram, Matrix, or WhatsApp.
Why use it?
It helps developers choose an integration approach without copying or forking the agents-lab project, while keeping budgets and checks under central control.

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.

Token cost

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.

Security

Grade A, and why

embed-pi-cli 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 2d 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.

Embed Pi CLI

Use este skill quando o objetivo for tornar um projeto CLI externo capaz de usar as capacidades do pi (orquestração, budget, observabilidade) sem forkar o agents-lab.

Escolha o modelo de integração

Antes de qualquer implementação, identifique qual modelo se aplica:

A — Config embedding (mais simples): o projeto só precisa de uma configuração pré-definida. Distribua .pi/settings.json no repositório.

B — Extension bundle (controle total): o projeto tem comportamentos customizados. Publique um pacote npm com extensões próprias.

C — Subprocess bridge (integração programática): o projeto orquestra pi de fora (CI, pipeline). Invoque pi como subprocesso e consuma sessões JSONL.

D — Message adapter (ex.: Telegram/Matrix/WhatsApp): canal externo envia comandos/steering para o control plane. Trate o canal como UI degradada: ele pode acionar loops, acompanhar checkpoints e receber resumos, mas não é autoridade canônica e não bypassa budget/delivery/verification gates.

Se não tiver certeza, comece com A e evolua para B se precisar de tools/commands próprios.

Fluxo recomendado

1) Definir o modelo

Responda:

  • O projeto precisa de tools ou commands customizados? → B ou C
  • O projeto invoca pi de CI/automação? → C
  • Só precisa de configuração? → A

2) Implementar

Para modelo A:

  1. Criar .pi/settings.json com packages + config de budgetPolicy e deliveryPolicy
  2. Documentar no README: pré-requisitos, pi install, comando de início
  3. Testar com PI_CODING_AGENT_DIR=/tmp/teste-isolado pi

Para modelo B:

  1. Criar pacote com estrutura packages/meu-pi-stack/
  2. Entry point exporta função default(pi: ExtensionAPI)
  3. Extensions em extensions/, skills em skills/
  4. Publicar como @meu-org/pi-stack e testar com pi install npm:@meu-org/pi-stack

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.

embed-pi-cli is a skill published in the GitHub repository aretw0/agents-lab (11 stars, last pushed 2mo ago), licensed MIT. It adds 45 tokens to every session and 1,111 once invoked, about $0.0002 per session on Opus 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.
