pneuma-session

pneuma-session is a skill for Claude Code, Codex from pandazki/pneuma-skills. It costs 127 tokens per session (2,543 once invoked), scanned A, original, MIT.

Instructions for renaming an active Pneuma session and replacing its default preview with a useful title and summary. A Pneuma session is one work area inside a larger project.

In plain words
What is it for?
Use it after substantial work or when asked to summarize a session, so the session title and description accurately describe its current topic.
Why use it?
It makes sessions distinguishable in the launcher and project list, especially when several sessions use the same mode.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

pneuma-session 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Refining your session's identity

Every Pneuma session has a row in the launcher (Recent Sessions) and inside its project (ProjectPanel). The row has two slots:

  • Title — defaults to "<Mode> session" (e.g. "WebCraft session"). Mode-only.
  • Description / preview — defaults to the first user prompt. For project sessions, the first prompt is the server-emitted <pneuma:env reason="opened" /> synthetic tag — which carries zero information for a human scanning the list.

Until you refine, both fields are placeholders. Three "WebCraft session" rows look identical except for their thumbnails. The user has to remember by time, which they won't.

This skill is how you fix that. You write a meaningful title + one-sentence summary into <sessionDir>/session.json, and the launcher row updates in place. The data persists across reopens; the launcher's own listing always reads from your last refine.

The mechanism

$PNEUMA_CLI session refine --json '{"displayName": "<≤40 chars>", "description": "<≤280 chars>"}'

Always call through the $PNEUMA_CLI env var, not the literal pneuma binary. The env var resolves to the right invocation regardless of how Pneuma was installed (npm-global, dev worktree, desktop bundle); writing the literal pneuma session refine only works when the binary happens to be on PATH, which it usually isn't inside the agent's sandbox. $PNEUMA_CLI is a single executable path, so the call behaves the same in bash, zsh, and fish, quoted or unquoted.

The command POSTs to the running Pneuma server (via $PNEUMA_SERVER_URL), which atomically rewrites <sessionDir>/session.json, syncs the global registry at ~/.pneuma/sessions.json, and broadcasts an event so any open browsers refresh the row without a reload.

Both fields are optional. Sending just displayName rewrites only the title; just description rewrites only the summary. Send both when the session has changed enough to warrant a fresh pair. The server validates lengths and rejects empties.

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.
