Purpose & Capability
Name/description, SKILL.md, clawhub.json, and trader.py all describe a Polymarket O/U curve arbitrage trader. The only external dependency is simmer-sdk and the single env var SIMMER_API_KEY, which matches the stated need for trading authority.
✓
Instruction Scope
SKILL.md instructs running trader.py (paper by default, live only with --live). The instructions and code focus on discovering O/U markets, building probability curves, detecting violations, and placing trades — no instructions to read unrelated files, secrets, or system state.
✓
Install Mechanism
There is no custom download/install script; dependencies are a PyPI package (simmer-sdk) declared in clawhub.json and SKILL.md. This is a typical install method for a Python skill; the package source is linked to a GitHub repo in the SKILL.md which is expected for this use.
✓
Credentials
The skill requires a single high-value credential, SIMMER_API_KEY, and uses a set of tunable environment variables (risk parameters) that are optional/adjustable. The code only reads these declared variables and nothing else, so requested environment access is proportionate to trading functionality.
✓
Persistence & Privilege
The skill is not marked always:true, autostart is false, and the automaton entrypoint exists but defaults to paper mode. It does not request system-wide persistence or modify other skills. Autonomous invocation remains platform-default and is not in itself a concern.
Assessment
This skill appears coherent: it needs only your SIMMER_API_KEY to place trades and defaults to paper trading unless you pass --live. Before installing, verify the simmer-sdk package source (the SKILL.md links a GitHub repo), start in paper mode to confirm behavior, and keep the following in mind: treat SIMMER_API_KEY as a high-value secret (do not reuse keys with broader privileges), review the simmer-sdk repo to ensure it calls only expected Simmer/Polymarket endpoints, and only enable live trading once you're comfortable with the tunables and trade-sizing logic. If you want extra caution, run the code in an isolated environment or audit the rest of trader.py (full file) to confirm there are no unexpected network calls or telemetry beyond the Simmer client.

Like a lobster shell, security has layers — review code before you run it.
