autonomy upgrade to AgenC. added four typed local tools and proved them on the live agent path: - system.sqliteSchema - system.sqliteQuery - system.pdfInfo - system.pdfExtractText desktop-mode sessions were silently hiding certain host-side typed tools, so the agent was falling back to shell instead. after the fix, AgenC routes correctly. answers are grounded in real schema, real rows, real PDF metadata and text. no more improvising with desktop.bash. add the right typed tool. verify it through the real user path. use full trace coverage to find the exact failure boundary. fix the runtime. lock it into the test ladder. next: typed office/spreadsheet/productivity tools. goal is handling the 2026 computer-use workload without dropping to brittle shell and browser hacks.
