From 28fce08dd9976fe2e97fe43cf2385107eb36e830 Mon Sep 17 00:00:00 2001 From: Will Anderson Date: Mon, 22 Jun 2026 11:22:14 -0500 Subject: [PATCH] feat(soul): context quality, first-message profile load, refusal handling, agentic safety - engram_compile: rank search results by recency x relevance before including in context. Pulls 20 candidates, scores each (salience * importance * recency decay), keeps top 8. Eliminates stale/low-signal nodes that diluted context. - handle_chat: on hist_len==0 (session start), proactively load user profile and active-work context from engram and inject as brief bullets in the system prompt. Gives the soul grounding before any conversation history exists. - build_system_prompt: add [CAPABILITY GAPS] directive instructing the soul to offer partial help and reasoning instead of flat "I don't have access to that" refusals when a tool is missing. - handle_chat_agentic: run safety_screen at entry, mirroring layered_cycle. Hard bell exits immediately with the crisis response without entering the loop. - agentic_loop: surface the 8-iteration cap explicitly in the error envelope ("agentic loop hit the 8-iteration cap...") rather than the opaque "no response". Add iterations count to both the error and success envelopes for observability. --- chat.el | 218 +++++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 210 insertions(+), 8 deletions(-) diff --git a/chat.el b/chat.el index 913259d..f538534 100644 --- a/chat.el +++ b/chat.el @@ -12,15 +12,125 @@ fn chat_default_model() -> String { return "claude-sonnet-4-5" } +// engram_score_node — compute a recency x relevance score for a single engram +// node JSON object.
