Changed the definition of "search_workspace"
Findsentities across everyanythingtoolinbythenameworkspace in one call — uploaded files (searching the text inside them), folders, Workbench flows, shims, knowledge bases and tasks, Compass pages and changes, Caliper datasets, evals, rubrics, reviews, specs and sources(apps sending agent traces), Ledger entries, Napkin sketches, decks, docs, sheets, diagrams anddecks.interfaces. The same search the person uses in Home. Use it FIRSTwhenwhenever the usernamesmentions something without saying where it lives ('theonboardingSOW',flow''the dispatch interviews', 'thatinvoice page'invoice');.reachTheforqueryaistool'swordsowninlistanyonlyorder:wheneachyouwordalreadymustknowappear in thetool.thing's name, its tags, the names of the folders it's filed under, or the text inside it — so 'northwind sow' finds the SOW filed in the Northwind folder, and 'dispatch interview' finds 'Dispatcher interview 1.md'. Results are ranked best first. Each hit carries its id, kind,andpathworkspace-relative(forpatha link),sofolderPath (where it's filed, top-down), tags, and a snippet when the words were found inside it rather than in its name — say where a thing lives using folderPath. A file's id feeds workspace_files_read; other ids feed thematchingkind's *_gettooltool. Pass folderId to search only inside one folder and everything under it. If nothing comes back, try fewer or different words before telling thepathusermakesitadoesn'tlink.exist. Results only include what the user can see ⟨7 unchanged words⟩
