pocket-i-lab

pocket-i-lab is a skill for Codex from yukakust/joinmultiplayer.ai. It costs 77 tokens per session (534 once invoked), scanned A, original, MIT.

A guide for connecting a Codex task to a consent-based, public experiment journal on joinmultiplayer.ai. The journal records filtered prompts, answers, tool status, selected file changes, and completion state after removing secrets and paths.

In plain words
What is it for?
Use it to start, continue, inspect, finish, or document an accepted Pocket i experiment, including experiments involving a small physical device swarm.
Why use it?
It explains how to publish an experiment record while keeping the work in the current Codex task. It also makes the public nature of the journal and the need for explicit opt-in clear.

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

pocket-i-lab 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 7d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pocket i Lab

This skill keeps the user inside their normal Codex task. Plugin hooks write the journal; never launch another codex exec process.

Start

Tell the user that the journal is public and filtered, then ask them to send this exact opt-in prompt if they have not already done so:

$pocket-i-lab start E002 as <pseudonym>

Use E003 instead when the user is working on the first three-device physical swarm. Only experiments currently accepted by the laboratory API can start.

Use anonymous when they do not want a pseudonym. Starting means explicit consent to publish the filtered journal. The hook returns the public run URL as additional context. Repeat that URL to the user.

While active

Continue the requested experiment normally in this same task. The hooks publish:

  • the user's submitted prompt after local secret and path redaction;
  • the final visible assistant message for each turn after the same redaction;
  • tool name and completion status only;
  • changed relative file names for apply_patch, never patch contents;
  • session completion state.

The hooks never read the transcript file and never publish hidden reasoning, tool arguments, shell commands, command output, tool output, file contents, environment variables, absolute paths, credentials, session identifiers, or the private run key.

At meaningful scientific checkpoints, write the result clearly in the visible assistant message: hypothesis, change, test, metric, failure, or decision. The public journal should be understandable without exposing private execution details.

Do not describe an unverified result as proof. Preserve failed experiments and distinguish synthetic, development, locked, and replicated results.

Finish

When the user wants to close the run, ask them to send:

$pocket-i-lab finish

The hook marks the run completed before the turn starts. Give a concise final summary and the public journal URL. Starting a later experiment creates a new run.

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.
