From 541d24b47861b28397a468a4cae41217cd0b47ee Mon Sep 17 00:00:00 2001 From: Daniel Smolsky Date: Sun, 7 Dec 2025 20:27:51 -0500 Subject: [PATCH 01/13] Refactor: Replace synthetic injection with system message injection - Remove brittle 'synthetic injection' logic that modified user messages. - Introduce 'injectSystemMessage' to FormatDescriptor interface. - Implement system message injection for OpenAI, Bedrock, and Gemini. - Update 'prune' tool prompt to focus on distillation workflow. - Remove obsolete prompt files (synthetic.txt, system-reminder.txt). - Simplify handler.ts to treat prunable lists as system instructions. --- index.ts | 13 +--- lib/fetch-wrapper/formats/bedrock.ts | 52 +++----------- lib/fetch-wrapper/formats/gemini.ts | 51 ++++--------- lib/fetch-wrapper/formats/openai-chat.ts | 57 ++++----------- lib/fetch-wrapper/formats/openai-responses.ts | 53 +++----------- lib/fetch-wrapper/handler.ts | 56 +++++++-------- lib/fetch-wrapper/index.ts | 10 ++- lib/fetch-wrapper/prunable-list.ts | 14 +--- lib/fetch-wrapper/types.ts | 10 +-- lib/prompts/synthetic.txt | 40 ----------- lib/prompts/system-reminder.txt | 3 - lib/prompts/tool.txt | 72 ++++++------------- 12 files changed, 107 insertions(+), 324 deletions(-) delete mode 100644 lib/prompts/synthetic.txt delete mode 100644 lib/prompts/system-reminder.txt diff --git a/index.ts b/index.ts index c401802..1328d3c 100644 --- a/index.ts +++ b/index.ts @@ -8,7 +8,6 @@ import { installFetchWrapper } from "./lib/fetch-wrapper" import { createPruningTool } from "./lib/pruning-tool" import { createEventHandler, createChatParamsHandler } from "./lib/hooks" import { createToolTracker } from "./lib/fetch-wrapper/tool-tracker" -import { loadPrompt } from "./lib/core/prompt" const plugin: Plugin = (async (ctx) => { const { config, migrations } = getConfig(ctx) @@ -40,17 +39,11 @@ const plugin: Plugin = (async (ctx) => { } ) - // Create tool tracker and load prompts for synthetic instruction injection + // Create tool tracker for nudge injection const toolTracker = createToolTracker() - const prompts = { - synthInstruction: loadPrompt("synthetic"), - nudgeInstruction: loadPrompt("nudge"), - systemReminder: loadPrompt("system-reminder") - } - - // Install global fetch wrapper for context pruning and synthetic instruction injection - installFetchWrapper(state, logger, ctx.client, config, toolTracker, prompts) + // Install global fetch wrapper for context pruning and system message injection + installFetchWrapper(state, logger, ctx.client, config, toolTracker) // Log initialization logger.info("plugin", "DCP initialized", { diff --git a/lib/fetch-wrapper/formats/bedrock.ts b/lib/fetch-wrapper/formats/bedrock.ts index bde93b5..566f5a1 100644 --- a/lib/fetch-wrapper/formats/bedrock.ts +++ b/lib/fetch-wrapper/formats/bedrock.ts @@ -1,42 +1,6 @@ import type { FormatDescriptor, ToolOutput } from "../types" import type { PluginState } from "../../state" -function isNudgeMessage(msg: any, nudgeText: string): boolean { - if (typeof msg.content === 'string') { - return msg.content === nudgeText - } - return false -} - -function injectSynth(messages: any[], instruction: string, nudgeText: string, systemReminder: string): boolean { - const fullInstruction = systemReminder + '\n\n' + instruction - for (let i = messages.length - 1;
