 ## [Unreleased]

+
+### Added
+- Codex multi-agent support: `request_user_input` mapping, multi-agent config, and agent role generation for Codex runtime
+- Analysis paralysis guard in agents to prevent over-deliberation during planning
+- Exhaustive cross-check and task-level TDD patterns in agent workflows
+- Code-aware discuss phase with codebase scouting — `/gsd:discuss-phase` now analyzes relevant source files before asking questions
+
+### Fixed
+- Update checker clears both cache paths to prevent stale version notifications
+- Statusline migration regex no longer clobbers third-party statuslines
+- Subagent paths use `$HOME` instead of `~` to prevent `MODULE_NOT_FOUND` errors
+- Skill discovery supports both `.claude/skills/` and `.agents/skills/` paths
+- `resolve-model` variable names aligned with template placeholders
+- Regex metacharacters properly escaped in `stateExtractField`
+- `model_overrides` and `nyquist_validation` correctly loaded from config
+- `phase-plan-index` no longer returns null/empty for `files_modified`, `objective`, and `task_count`
