TL;DR

The issue can be resolved by allowing tool registrations to provide an explicit toolset-level availability check and registering the browser toolset with check_browser_requirements().

Guidance

• The root cause is due to the order of imports in hermes doctor, where browser_cdp_tool.py is imported before browser_tool.py, causing the registry to capture browser_cdp's stricter check_fn as the browser toolset check.
• To verify the issue, run hermes doctor without configuring browser.cdp_url / BROWSER_CDP_URL and check if it reports ⚠ browser (system dependency not met).
• To mitigate the issue, consider modifying the import order or providing an explicit toolset-level availability check for the browser toolset.
• The proposed fix involves registering the browser toolset with check_browser_requirements() while keeping browser_cdp gated on CDP availability.

Example

No code snippet is provided as the issue does not require a specific code change, but rather a change in the registration process.

Notes

The provided information does not include the actual code changes required to implement the proposed fix, which is expected to be included in the upcoming PR.

Recommendation

Apply workaround: wait for the upcoming PR that includes the targeted fix and regression test, and then apply the changes to resolve the issue. This is recommended because the proposed fix is already being worked on and will likely provide a more comprehensive solution.
