Automated README summary
Automatically summarized from the README on 3 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Switchyard is a macOS menu-bar app that becomes the default browser and sends each http/https link to the right browser profile, using local rules and optional AI guesses. It is for people who split work, personal and side-project browsing across profiles or browsers.
How it uses Jev
When no rule matches, Switchyard sends Jev the host, first three path segments and query parameter names, plus profile descriptions. Jev returns a Choice over profiles and a Choice over URL scope. If profile confidence is at least 0.7 (adjustable), the link opens there and a rule is saved at the chosen scope; otherwise the picker shows Jev's guess.
Primitives:choice
Technique worth stealing
Ask one model call for two linked choices at once: destination profile and the URL scope a rule should cover.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
