Understanding Cross-Phase Stacking
Overview
Phases automatically build on each other's completed work. Understanding how phases chain together is essential for correct execution.
This is a reference skill - read it to understand cross-phase dependencies, not to execute a workflow.
When to Use
Use this skill when:
- Starting a new phase (need to understand what base to build from)
- Debugging stack relationships across phase boundaries
- Verifying phases are chaining correctly
- Understanding why parallel worktrees use specific base branches
Mental model check: If you're thinking "create worktrees from {runid}-main branch", you need this skill.

using-git-spice
Use when working with stacked branches, managing dependent PRs/CRs, or uncertain about git-spice commands (stack vs upstack vs downstack) - provides command reference, workflow patterns, and common pitfalls for the git-spice CLI tool
33writing-specs
Complete spec workflow - generates Run ID, creates isolated worktree, brainstorms requirements, writes lean spec documents that reference constitutions, validates architecture quality, and reports completion
19executing-plan
Use to execute an implementation plan with automatic sequential/parallel orchestration - handles worktree verification, resume detection, phase dispatch, and quality verification
10troubleshooting-execute
Use when execute command encounters errors - diagnostic guide for phase failures, parallel agent failures, merge conflicts, worktree issues, and recovery strategies
7decomposing-tasks
Use when you need to create an execution plan from a feature spec - handles worktree context, dispatches subagent for task decomposition, validates quality, analyzes dependencies, groups into phases, and commits the plan
7versioning-constitutions
Use when architectural patterns evolve, tech stack changes, or foundational rules need updates - creates new constitution version directory, migrates/organizes content into modular files, updates symlink, and documents changes
