Micropolis Command Bus

What it does

When your agent uses it

• Agents need to inspect
• Dispatch Micropolis commands

Example prompts

• “Use the micropolis-command-bus skill to route all Micropolis UI, CLI, MCP, chat, pie menu, and LLM actions through a safe command bus with…”
• “/micropolis-command-bus”

Requirements

• Pre-approved tools (allowed-tools): read_file, write_file, run_terminal_cmd

Workflow steps

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

1. 1GLANCE.yml — quick activation check
2. 2CARD.yml — machine-readable interface, advertisements, methods
3. 3SKILL.md — this operational protocol
4. 4README.md — deeper human-facing rationale

What it can do on your machine

Read from SKILL.md and the folder at commit 5e78c58. 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:

  • read_file
  • write_file
  • run_terminal_cmd

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm

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

• Network

  No URLs in SKILL.md. Its commands use npm, 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

Micropolis Command Bus loads about 1.5k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 549 words of instructions outside code blocks.

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

~60

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

~1.5k

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.
