skills_lab_downloader

To install an ESP-Claw skill, you request the exact skill name from the skills-lab.esp-claw.com hub. The downloader fetches _metadata.json, validates hardware compatibility, and streams the files directly to your device's /fatfs/skills/ directory.

Metadata validation checks peripheral compatibility by comparing the required peripherals listed in the skill's _metadata.json file against the actual available hardware exposed by the board_hardware_info, preventing incompatible installs.

Yes, downloading skills requires the cap_http_request capability to handle the HTTP download flow. The installation process checks that the hub host is explicitly allowlisted before proceeding with the file transfer.

If the skills hub host is not on the HTTP allowlist, the secure HTTP handling guardrails will halt the download process immediately and provide clear guidance to resolve the host permission issue before proceeding.

No, exact-skill-name hub installation requires the internal skill name rather than the displayed title. The downloader uses this precise identifier to fetch the correct package from the skills-lab.esp-claw.com hub.

Installation fails before streaming files if metadata validation detects a mismatch between the skill's required peripherals and your board_hardware_info, or if the HTTP download host lacks proper allowlisting.
