From ee50fb8528fde7b24ec216390b3620a6c89b4557 Mon Sep 17 00:00:00 2001 From: spiceoogway Date: Fri, 30 Jan 2026 01:01:41 -0500 Subject: [PATCH 1/5] fix: slug-generator uses configured default model instead of hardcoded Opus Resolves #4315. The slug-generator embedded run was hardcoded to use DEFAULT_MODEL (claude-opus-4-5) regardless of the user's configured agents.defaults.model.primary. This caused unexpected Opus charges on every /new command. Now uses resolveDefaultModelForAgent() to honor the user's configured default model, falling back to DEFAULT_MODEL only when no config exists. --- src/hooks/llm-slug-generator.ts | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/src/hooks/llm-slug-generator.ts b/src/hooks/llm-slug-generator.ts index c52627176..024262a5d 100644 --- a/src/hooks/llm-slug-generator.ts +++ b/src/hooks/llm-slug-generator.ts @@ -12,6 +12,7 @@ import { resolveAgentWorkspaceDir, resolveAgentDir, } from "../agents/agent-scope.js"; +import { resolveDefaultModelForAgent } from "../agents/model-selection.js"; /** * Generate a short 1-2 word filename slug from session content using LLM @@ -38,6 +39,11 @@ ${params.sessionContent.slice(0, 2000)} Reply with ONLY the slug, nothing else.

This could split assistant messages (with tool_use) from their corresponding tool_result blocks, creating orphaned tool_result blocks that the Anthropic API rejects. This fix calls sanitizeToolUseResultPairing() AFTER limitHistoryTurns() to repair any pairings broken by truncation, ensuring the transcript remains valid before being sent to the LLM API.
