chess-results

• Outcome: Pass
• Latest audit: Oct 5, 2026 · 4:45 PM UTC
• Version: 0.2.0

Overview

This skill is a disclosed Chess-Results helper that queries public pages and can enter league results only through user-approved, credential-backed workflows.

Install only if you are comfortable giving the skill access to your Chess-Results account for result entry. Use the check workflow first, review the log carefully, and approve saving only when the filled report is correct, because saved results become visible to the league.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

- **Credentials:** only its own entry. On macOS it runs
  `/usr/bin/security find-generic-password -s chess-results` and
  `add-generic-password -s chess-results` (written by `cli.py login`), nothing else.
  It does not read SSH keys, cloud credentials, browser passwords, iCloud Keychain or
  other Keychain items. Scanners that flag "credential access" are seeing this.
- **Agent configuration:** the code never reads `~/.claude`, `~/.codex`, `~/.openclaw`
  or similar. SETUP.md *tells the user* which lines to add to their own Codex or
