Dr Manhattan

What it does

When your agent uses it

• The user wants to browse
• Trade prediction markets
• Check balances and positions
• Run market-making strategies

Example prompts

• “/dr-manhattan”

Requirements

• Python 3
• Compatibility (from SKILL.md): Requires Python >= 3.11 and uv. Requires network access for exchange APIs. Optionally requires exchange credentials (private keys, API keys) for trading.

Workflow steps

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

1. 1Use search_markets with a keyword to find relevant markets.
2. 2Pick a market from the results and note its id and metadata.clobTokenIds.
3. 3Use get_orderbook with a token ID to see current bids and asks.
4. 4Use get_best_bid_ask for a quick spread check.

What it can do on your machine

Read from SKILL.md and the folder at commit 7c15fad. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/, which the agent can run.

  Shell commands in SKILL.md call:

  • uv

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

• Network

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

• Compatibility

  Requires Python >= 3.11 and uv. Requires network access for exchange APIs. Optionally requires exchange credentials (private keys, API keys) for trading.

  From compatibility in the SKILL.md frontmatter.

Context cost

Dr Manhattan loads about 2k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 668 words of instructions outside code blocks.

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

~77

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

~2k

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); the scripts in this folder are not scanned.
