Tiny Game Controller

What it does

When your agent uses it

• Playing or exploring a running Tiny game through the agent
• Testing game input handling with scripted key presses
• Tapping or holding keys to reproduce a bug in a game level

Example prompts

• “Move the character right for half a second, then jump.”
• “Press space three times and take a screenshot of the result.”
• “List the keys the running game accepts.”

Requirements

• A Tiny game running via tiny-cli with its debug server on port 8081
• curl
• Pre-approved tools (allowed-tools): Bash(curl:*), Bash(sleep:*), Read, mcp__playwright__browser_take_screenshot, mcp__playwright__browser_navigate, mcp__playwright__browser_snapshot

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1If arguments describe an action (e.g., "move right", "jump", "press space 3 times")
2. 2If arguments are a key name (e.g., "SPACE", "ARROW_LEFT")
3. 3If no arguments or "help"
4. 4If "play" or complex instructions (e.g., "play the game", "explore the level")

What it can do on your machine

Read from SKILL.md and the folder at commit 876365c. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(curl:*)
  • Bash(sleep:*)
  • Read
  • mcp__playwright__browser_take_screenshot
  • mcp__playwright__browser_navigate
  • mcp__playwright__browser_snapshot

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tiny Game Controller loads about 874 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 284 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~50

When it runs · the whole SKILL.md, loaded when a task matches

~874

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
