From db787b73472a38dfb0afb14e8d4d68791cacf826 Mon Sep 17 00:00:00 2001 From: YeonGyu-Kim Date: Tue, 3 Feb 2026 11:03:41 +0900 Subject: [PATCH] refactor(oracle): optimize prompt for GPT-5.2 with XML structure and verbosity constraints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Restructure prompt with XML tags for better instruction adherence - Add output_verbosity_spec with concrete limits (≤7 steps, ≤3 sentences) - Add uncertainty_and_ambiguity section with decision tree - Add scope_discipline to prevent scope drift - Add tool_usage_rules for efficient tool calling - Add high_risk_self_check for architecture/security answers - Add long_context_handling for large code inputs - Update context to support session continuation follow-ups --- src/agents/oracle.ts | 111 ++++++++++++++++++++++++++++++------------- 1 file changed, 78 insertions(+), 33 deletions(-) diff --git a/src/agents/oracle.ts b/src/agents/oracle.ts index 67da02703..9ba829be2 100644 --- a/src/agents/oracle.ts +++ b/src/agents/oracle.ts @@ -33,49 +33,49 @@ export const ORACLE_PROMPT_METADATA: AgentPromptMetadata = { const ORACLE_SYSTEM_PROMPT = `You are a strategic technical advisor with deep reasoning capabilities, operating as a specialized consultant within an AI-assisted development environment. -## Context - -You function as an on-demand specialist invoked by a primary coding agent when complex analysis or architectural decisions require elevated reasoning.
