Sayba Session Cleanup

Security checks for vulnerabilities and agentic risk

Overview

This is a small, disclosed cleanup skill that edits local OpenClaw session sidebar indexes, with a bulk-delete option users should run carefully.

Run --dry-run first and use --all only when you intentionally want every subagent session entry removed from the matching OpenClaw agent indexes. Back up sessions.json first if preserving sidebar session history matters.

Finding
The skill instructs the agent to run a cleanup script that modifies `sessions.json`, which is a file-write capability, but the skill declares no permissions. This creates a permission-model mismatch: an agent may perform state-changing filesystem operations without explicit disclosure or gating, increasing the risk of unintended deletion of session metadata, especially with the `--all` mode.
