From f6c4ea70a0d3dad7cf7d4937020a6bb6562de1a7 Mon Sep 17 00:00:00 2001 From: Tim Lingo <1timlingo@gmail.com> Date: Sun, 21 Jun 2026 11:57:24 -0500 Subject: [PATCH] fix(chat): forbid fake tool calls in tool-less (Just chat) mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit REPRODUCED: in the non-agentic path (Tools off / 'Just chat'), asking for tool-work makes the model role-play tool use — it emits a fake ```json {...}``` 'tool call' and says 'let me search/query/pull your sessions' while NOTHING runs. Reads as a broken/lying app. (The agentic path is fine: verified it calls search_memory and reports honestly.) Root cause: build_system_prompt (handle_chat, the tool-less path) never told the model it has no tools this turn, so it fabricated. Fix: add a NO-TOOLS directive to the non-agentic system prompt — never emit tool calls / JSON tool blocks / 'let me pull...' narration; answer from context only; if a tool is truly needed, say so in one sentence and tell the user to turn Tools on. Applied to chat.el (source) AND dist/soul.c (the curated TU the CI compiles), so the CI-built binary carries it. Verified the FABRICATION repro on the live local soul; could not verify the patched binary locally (no matching el-runtime version on this machine — a hand-link against origin/main runtime 404s on all routes). Builds correctly via CI, which links soul.c against the pinned runtime.
