From 67f98f4f35b8a0506a4abca0fdf70c5b905c38e7 Mon Sep 17 00:00:00 2001 From: Lukas May Date: Wed, 18 Feb 2026 17:30:00 +0900 Subject: [PATCH] refactor: Compress execute prompt for conciseness (~47% word reduction) - Cut 5 anti-patterns: placeholder code, blind imports, ignoring test failures (all default Claude behavior), plus self-validating tests and test mutation (both already covered by TEST_INTEGRITY in shared.ts) - Compressed execution protocol steps to imperative essentials - Merged scope rules from 4 bullets to 3 - Trimmed definition of done checklist (removed redundant 5th item) - Removed anti-laziness language (IMPORTANT, MUST, aggressive emphasis) --- src/agent/prompts/execute.ts | 56 ++++++++++++++---------------------- 1 file changed, 22 insertions(+), 34 deletions(-) diff --git a/src/agent/prompts/execute.ts b/src/agent/prompts/execute.ts index dad1ec2..5b58753 100644 --- a/src/agent/prompts/execute.ts +++ b/src/agent/prompts/execute.ts @@ -18,10 +18,7 @@ export function buildExecutePrompt(taskDescription?: string): string { ? `\n## Task (inline summary)\n\n${taskDescription}\n\nRead \`.cw/input/task.md\` for the full structured task with metadata, priority, and dependencies.` : ''; - return `You are a Worker agent in the Codewalk multi-agent system. - -## Your Role -Execute the assigned coding task.
