From a22a146651852b3f6d7c662c8973ce0dcf51cacd Mon Sep 17 00:00:00 2001 From: prosdev Date: Sun, 23 Nov 2025 07:50:47 -0800 Subject: [PATCH 1/6] feat(planner): add types and utility functions Implements foundational types and pure utility functions for the Planner Subagent following the Explorer gold standard pattern. Types: - GitHubIssue, Plan, PlanTask interfaces - PlanningRequest/Result for agent communication - BreakdownOptions, PlanOptions for configuration Utilities (domain-specific modules): - github.ts: GitHub CLI interaction (fetch issues, check installation) - parsing.ts: Extract criteria, requirements, priority from issues - breakdown.ts: Break issues into actionable tasks - estimation.ts: Calculate effort estimates - formatting.ts: Output formatters (pretty, markdown, JSON) Agent Skeleton: - PlannerAgent class implementing Agent interface - Placeholder createPlan method - Health checks and lifecycle methods All utilities are pure functions, designed for 100% test coverage.
