Kernel CLI v0.35.0

Highlights

• Add kernel browsers webmcp list <id-or-name> to discover native page tools across browser tabs and embedded frames. Use --json or -o json to include tool descriptions, input schemas, annotations, and source details. (#247)
• Add kernel browsers webmcp invoke <id-or-name> --tool-ref <ref> to invoke a discovered tool with a JSON object supplied through --input, --input-file, or stdin. Supports --timeout-sec and prints completed tool output as JSON. Invocations are never retried automatically; errors and cancellations exit non-zero, and unknown outcomes retain the invocation ID for investigation. (#247)
• Add per-action tool-call logging, tool-failure messages, and agent narration to the TypeScript anthropic-computer-use, gemini-computer-use, and openai-computer-use templates. (#241)

WebMCP tool references expire when their document or browser process is replaced. Page-provided annotations and output are untrusted. After an unknown outcome, verify whether the tool had side effects before invoking it again.
