Description
Filter Polymarket prediction markets and track probabilities. Use when screening bets, drafting analyses, outlining trends, tracking price movements.
Usage Guidance
This skill appears to do what it says: it queries Polymarket's public API and writes local cache/reports. Things to check before installing or running: 1) Note the filename mismatch—SKILL.md shows scripts/polymarket-screener.sh but the repo provides scripts/polymarket.sh; confirm which script you'll run. 2) The bundle includes an extra content-assistant script that logs user input to ~/.polymarket-screener (or the XDG data path); if you plan to run prompts or paste sensitive text, be aware those local logs will store it. 3) No credentials are requested and network calls go only to polymarket endpoints listed in the scripts (gamma-api.polymarket.com and polymarket.com). If you want extra caution, run the scripts in a sandbox/container or inspect the files locally, and optionally set POLYMARKET_SCREENER_DIR to a chosen location before running so you know where files are written.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-screener
Version: 2.0.1
The skill bundle provides a tool for screening Polymarket prediction markets using their public API. While the bundle is poorly constructed—containing significant inconsistencies between the documentation (SKILL.md) and the scripts, including mismatched filenames and an entirely unrelated content-creation script (scripts/script.sh)—the code itself is non-malicious. It interacts only with the legitimate Polymarket API (gamma-api.polymarket.com), stores data locally in the user's home directory, and contains no evidence of data exfiltration, backdoors, or prompt injection attacks.
Capability Assessment
Purpose & Capability
Overall the files and instructions align with a Polymarket screener: the scripts query Polymarket's public API, compute simple filters/scores, and write local cache/report files. Small inconsistencies: SKILL.md examples call scripts/polymarket-screener.sh and polymarket-screener commands, but the shipped executable is scripts/polymarket.sh; a second script (scripts/script.sh) is a content/marketing helper (content-drafting CLI) that is not described in SKILL.md. These are coherence issues but plausibly explainable (naming/packaging mismatch), not evidence of hidden functionality.
Instruction Scope
Runtime instructions tell the user to run local shell scripts that fetch market data from Polymarket and produce reports; the scripts only access the network for polymarket endpoints and write to a per-user data directory (~/.polymarket-screener or XDG_DATA_HOME). The SKILL.md references a script name that doesn't match the file manifest, which could cause confusion or accidental invocation of the wrong script. The included content-assistant script logs commands to local history files, which may record user-provided text.
Install Mechanism
No install spec or external downloads are present; code is shipped as local shell/Python scripts. This is low-risk compared with remote installers or archives pulled from arbitrary URLs.
Credentials
The skill requires no credentials or special environment variables. It respects POLYMARKET_SCREENER_DIR / XDG_DATA_HOME / HOME for local storage. No unrelated secrets or config paths are requested.
Persistence & Privilege
always is false and the skill does not request permanent platform privileges. The scripts create and write only to a dedicated per-user data directory (~/.polymarket-screener or XDG data path) and do not modify other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-screener - After installation, invoke the skill by name or use
/polymarket-screener - Provide required inputs per the skill's parameter spec and get structured output
