A command-line controller for Pi, a coding agent that can run in the background and communicate through structured JSON messages.

It is for headless coding, independent code reviews, JSON-based integrations, and delegating tasks to Pi's skills and extensions.

It provides a way to delegate coding and review work to another agent while limiting its tools or connecting it to other programs.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 58
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.05883
Opus 5.5	$0.00011	$0.02353
Sonnet 5.5	$0.00005	$0.01177

Security

Grade A, and why

cli-pi 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 yesterday.

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 — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Canonical source: .skilled/skills/cli-external-orchestration/cli-pi/. This is a generated markdown-only copy so Hermes can load the skill without scanning the canonical directory. Read references/, assets/ and scripts/ from the canonical path above.

Pi CLI Orchestrator - Cross-AI Task Delegation

A Pi session MAY dispatch this skill. Pi has no in-process delegation of its own, so the CLI is the only way a Pi session can hand work out; being inside Pi is not a reason to refuse.

What still refuses: the shared runtime rejects a dispatch from inside a fan-out lineage, and one whose kind already appears in the dispatch stack. Those bound a runaway spawn chain and are unchanged. The sibling cli-X packets keep their own guards; this carve-out is Pi's alone.

Orchestrate Pi's terminal coding agent for headless coding, read-only tool-constrained reviews, JSON event-stream integrations, RPC clients, and Pi-native resource discovery. The pinned contract is the source for confirmed command behavior: Pi contract pin. Pi-native skills, prompt templates, and some package surfaces remain documented but unconfirmed unless a source says otherwise.

Core principle: use Pi for the surfaces it exposes, delegate research and review lineages to the shared runtime, validate the returned output, and keep the calling AI as conductor.

1. WHEN TO USE

Activation Triggers

Headless Pi dispatch: use when the task explicitly requests Pi, pi.dev, or the Pi coding agent.
Cross-AI validation: use for an independent implementation attempt, code review, or second opinion through Pi.
JSON event output: use when a caller needs Pi's line-delimited event stream.
RPC integration: use when a long-lived stdin/stdout protocol is explicitly requested.
Pi-native resources: use when the task concerns Pi skills, prompt templates, extensions, or installed packages.
Community package delegation: use when the task explicitly names pi-mcp-extension.

Changes

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.

cli-pi is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (38 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 5,883 once invoked, about $0.0001 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 2026-09-03.
