    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.

Security

Grade A, and why

pokemon-player 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 10d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pokemon Player

Play Pokemon games via headless emulation using the pokemon-agent package.

When to Use

  • User says "play pokemon", "start pokemon", "pokemon game"
  • User asks about Pokemon Red, Blue, Yellow, FireRed, etc.
  • User wants to watch an AI play Pokemon
  • User references a ROM file (.gb, .gbc, .gba)

Startup Procedure

1. First-time setup (clone, venv, install)

The repo is NousResearch/pokemon-agent on GitHub. Clone it, then set up a Python 3.10+ virtual environment. Use uv (preferred for speed) to create the venv and install the package in editable mode with the pyboy extra. If uv is not available, fall back to python -m venv + pip.

If a checkout already exists (e.g. ~/pokemon-agent with a venv ready), just cd there and source .venv/bin/activate instead of recloning.

You also need a ROM file. Ask the user for theirs (a previous setup may already have one at roms/pokemon_red.gb inside the checkout). NEVER download or provide ROM files — always ask the user.

2. Start the game server

From inside the pokemon-agent directory with the venv activated, run pokemon-agent serve with --rom pointing to the ROM and --port 9876. Run it in the background with &. To resume from a saved game, add --load-state with the save name. Wait 4 seconds for startup, then verify with GET /health.

3. Set up live dashboard for user to watch

Use an SSH reverse tunnel via localhost.run so the user can view the dashboard in their browser. Connect with ssh, forwarding local port 9876 to remote port 80 on the keyless localhost.run endpoint (ssh -R 80:localhost:9876 ssh://[email protected]). Redirect output to a log file, wait 10 seconds, then grep the log for the .lhr.life URL. Give the user the URL with /dashboard/ appended. The tunnel URL changes each time — give the user the new one if restarted.

Save and Load

When to save

  • Every 15-20 turns of gameplay
  • ALWAYS before gym battles, rival encounters, or risky fights
  • Before entering a new town or dungeon
  • Before any action you are unsure about

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.
