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

handoff-pneuma 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 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.

How it starts

The opening of the file, as written. The whole thing — 256 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are routing the user's request to Pneuma — a co-creation workspace that spins up a domain-specific viewer (a deck, a webpage, a board, a diagram, a video, …) plus an editing agent. Your job in this skill is to collect the minimum information needed, then call pneuma handoff-from-external, which mints the session and returns a URL.

The user's request that triggered this skill — whatever they asked you to hand off or build in Pneuma — is your INTENT. If they invoked you with a bare $handoff-pneuma and no description, treat INTENT as empty and ask for it in step 1.

Stop here if you are already inside a Pneuma session

This skill is for external agents (Codex / Claude Code running in the user's normal terminal) that want to hand off TO Pneuma. It is not the path for one Pneuma session to hand off to another.

If the environment variable PNEUMA_SESSION_ID is set (check echo "${PNEUMA_SESSION_ID:-}"), you are running INSIDE a Pneuma session. Do not proceed with the steps below — running pneuma handoff-from-external here spawns a brand-new external session, leaves your current session alive in "thinking" forever, and confuses the user with a second window.

Instead, in one short reply tell the user:

I should use Smart Handoff inside Pneuma, not the external handoff-pneuma flow. Trigger Smart Handoff from the UI (or just let me wait for the <pneuma:request-handoff> tag) and I'll prepare the handoff via $PNEUMA_CLI handoff.

Then end the turn. Do not call any bash commands, do not invoke pneuma handoff-from-external, do not call pneuma handoff on your own — the source for <pneuma:request-handoff> is always the user clicking Smart Handoff in the UI.

Steps

  1. Resolve INTENT and any options from the user's request:
    • INTENT — free-form text describing what the user wants built. May be empty.
    • mode (e.g. webcraft, slide, diagram) — optional, if the user named one.
    • project vs. quick — optional. A project initializes the current folder as a Pneuma Project (persistent, multi-session); quick skips project setup (one-off session).

It adds 117 tokens to every session and 3,142 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).
