# reload_themes Reload themes from /themes/. Call after creating or editing theme files. Agent View of the PolicyLayer registry record for `reload_themes`. HTML page: https://policylayer.com/tools/fistacho-ha-nexus-agent/reload-themes ## Facts - Tool: `reload_themes` - Server: Ha Nexus Agent (`fistacho/ha-nexus-agent`) — https://policylayer.com/tools/fistacho-ha-nexus-agent.md - Homepage: https://github.com/Fistacho/ha-nexus-agent - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "reload_themes", "arguments": {} } } ``` ## Why reload_themes is rated High This tool triggers a reload operation in Home Assistant, causing the system to re-read and apply theme configuration files. It executes an external operation (reloading system configuration) rather than simply reading or writing data. Misuse could cause visual disruption or apply malicious theme configurations, but blast radius is limited to UI appearance. From the tool's own definition: "Reload themes from `/themes/`. Call after creating or editing theme files." ## Use case AI agents invoke reload_themes to trigger actions in Ha Nexus Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
