From a333a3b8035aa84f02164324ac9cf3164b37b199 Mon Sep 17 00:00:00 2001 From: Tajudeen Date: Mon, 15 Jun 2026 12:33:08 +0100 Subject: [PATCH 1/5] fix(agent): give capable local coders (>=7B) the web tools + stop hallucinating on "check online" BUG (user-reported): with Auto -> a local model, "Check online and tell me when spacex ipo happened" did a CODEBASE/file search and then fabricated a confident false fact ("SpaceX IPO'd Dec 5 2015"; SpaceX has never IPO'd). Root cause (4-lens investigation): (1) web_search/browse_url are curated OUT of the local toolset for ALL local models, so the model can't browse; (2) "check online" wasn't recognized as web intent (keyword lists matched "search online"/"check the web" but not "check online"), so it fell through to a synthesized search_for_files; (3) the local prompt claimed it could "fetch current/web info" while the tools were removed; (4) no anti-hallucination guard, so it invented an answer. Fix (per the chosen direction -- enable web on CAPABLE local models): - New CAPABLE_LOCAL_TOOLSET = COMPACT_LOCAL_TOOLSET + web_search + browse_url, selected by localToolsetFor (prompts.ts). A capable local coder (>=7B, isCapableLocalCoder) gets the web tools at BOTH the prompt catalog (availableTools/systemToolsXMLPrompt/chat_systemMessage_local, threaded from convertToLLMMessageService) AND the execution chokepoint + offered-list (chatThreadService _runToolCall, threaded via recomputeModelState -> all 4 call sites). Small local models stay on COMPACT (no web). - Recognize "check online"/"go online"/"look online"/"search the internet"/"on the internet" as web intent in the task-type detector + tool-synthesis (chatThreadService) and the pure WEB_QUERY_WORDS (common/toolSynthesisDecision.ts). - Prompt: the local system message only claims web access when the web tools are actually offered (capable coder); a small local model is told it does NOT have web access and to say so instead of browsing/searching. - Anti-hallucination guard added to the local prompt: if a tool returns nothing or you lack a source/tool, say so -- never fabricate. The same isCapableLocalCoder signal (name + ollama param_size) is computed identically on both the prompt and chokepoint sides, so offered == executable. tsgo 0; common suite 888 -> 889 (+1: capable-toolset gate). Live re-test pending on the running build (a >=7B coder should now web-search "check online"; a small local model should refuse gracefully).

IPO on June 12, 2026 ... $135/ share"), but the local 7B model dismissed them as "unrelated" and answered from STALE training memory ("June 29 2019, $42" -- all false; SpaceX had not IPO'd before 2026). The search backend was fine (Method 1 Instant- Answer returns empty -> falls through to Method 2 DDG-HTML which returns the right results); the failure was GROUNDING -- the model overrode fresh retrieval with parametric memory, worsened by the prompt-injection fence labeling results "UNTRUSTED" (a weak model over-reads that as "don't trust the facts"). Fix: add a GROUNDING preamble to the web_search + browse_url tool RESULTS (stringOfResult): treat the FACTS in current web results as authoritative and PREFER them over training knowledge; answer ONLY from them; if the answer isn't present, say you couldn't find it instead of guessing. Crucially it distinguishes FACTS (use them) from INSTRUCTIONS (still don't obey, per the unchanged injection fence) -- so the anti-injection defense is NOT weakened. The empty-results string now also tells the model to say it couldn't find it rather than answer from memory. This is the harness-side lever; a 7B model may still occasionally override (model-honesty limit) -- the robust fix (constrained/structured decoding, stronger model) is tracked in the agent-mode modernization prompt. tsgo 0; no test delta (browser tool-result formatting). Live re-test pending.

Root cause: the renderer cannot fetch html.duckduckgo.com directly (CORS), so web_search routes through webContentExtractorService, which returns the page as accessibility-tree markdown (NOT raw HTML). The old parser walked raw character ranges and reconstructed `[title](decoded-url)` to locate snippets, but the markdown holds DDG's *redirect* URLs and interleaves the title / displayed-url / snippet links, with footnote markers ([12]) inside the snippet text -- so indexOf failed and the regex broke, yielding empty or garbage snippets. Fix: parse DDG's very regular per-result structure (## heading link = title; longest prose link-text = snippet; uddg= param = canonical url) with a footnote-aware link matcher. Extracted to a pure common/webSearchParse.ts so it is node-testable; 8 unit tests pin a golden fixture captured from the real extractor output (clean title/url/snippet, no redirect/encoded/footnote/markdown leakage, entity decoding, displayed-url rejection, ad filtering, maxResults). Live-verified over CDP: "when did SpaceX IPO happen" and "latest stable node.js LTS version" each return 5 clean results with correct, current facts (SpaceX IPO June 12, 2026; Node.js 24.11.0 LTS). 897 node tests pass (was 889; +8), tsgo 0, cdp-smoke 11/11.

Live CDP instrumentation of the real agent loop (not the tool in isolation) found TWO behavioral bugs downstream of the now-correct tool: 1. Bad SYNTHESIZED query. When the model gives up ("I do not know.") the harness synthesizes a web_search from intent. The query was built by extractKeywords = first 5 words after a tiny stop-word list, so "check online and tell me when SpaceX IPO'd" became "check online and tell when" -> DuckDuckGo returned "check online" (DVLA / vehicle-tax) results and the agent honestly reported it found nothing -- the real subject "SpaceX IPO" was dropped (past word 5). Fix: pure common/webSearchQuery.ts extractWebSearchQuery() strips the web-intent triggers + command/politeness framing and keeps the SUBJECT. 2. Self-limited result count. When the model emitted its OWN call it used k=1; that single snippet (a price/valuation blurb) had no date and the model FABRICATED "May 15, 2026". Fix: clamp web_search results to a floor of 5 (cap 10) so the answer-bearing snippet (Wikipedia "...IPO on June 12, 2026...") is present. Live-verified over CDP (qwen2.5-coder:7b, Agent mode, real chat). Before: bad query -> DVLA results -> "could not find"; k=1 -> fabricated "May 15, 2026". After: query "SpaceX IPO date" -> 5 results (hasJune12=true reaches the model) -> grounded answer "SpaceX completed its IPO on June 12, 2026 ... $135 per share." 13 new unit tests (incl. the exact regression case); 897->909 node tests, tsgo 0.

SpaceX IPO" in AUTO mode surfaced a distinct bug from the qwen2.5-coder path. Auto resolved to a capable GENERAL model (llama3:8b), which was DENIED web_search and fell back to stale training knowledge: Search the web "SpaceX IPO date" Error: The web_search tool isn't available for this model. Use one of: read_file, ... -> "SpaceX has not gone public through an IPO..." (WRONG) Root cause: web tools (web_search/browse_url) were gated on isCapableLocalCoder -- a CODER >=7B (codingModelScoreBonus>=25 AND >=7B). llama3:8b is capable but not a coder, so it got the COMPACT toolset (no web). Web search is a GENERAL capability, not coding-specific -- any sufficiently large local model should have it. Fix: new size-only gate isCapableLocalModel (>=7B, or unnumbered/flagship tag), used for the web-tool toolset decision at BOTH the prompt catalog (convertToLLMMessageService) AND the execution chokepoint (chatThreadService). Renamed the threaded toolset boolean isCapableLocalCoder -> isCapableLocalModel through prompts.ts/chatThreadService/convertToLLMMessageService for honesty; isCapableLocalCoder the FUNCTION stays (onboarding/routing still want a coder). Live-verified over CDP (fresh thread each, real chat): - Auto -> qwen2.5-coder:7b (7.6B): gate true, answers "June 12, 2026" correctly. - llama3:latest (8.0B, GENERAL, the original failure): gate now true at BOTH the chokepoint and the prompt; searches "SpaceX IPO date" (5 results) and answers "Based on the search results ... IPO on June 12, 2026 ... ticker SPCX." CORRECT. - llama3.2:3b (3.2B): gate correctly FALSE -- small models stay web-less. 909->913 node tests (+4 isCapableLocalModel cases incl. the llama3:8b regression), tsgo 0.
