## Description

Plan a feature or task in fast, full, or ultra mode. Ultra creates an indexed multi-file bundle with deeply specified phases for execution by a smaller model. Use for "plan", "new feature", "start feature", "create tasks", or exhaustive implementation planning.

# Plan - Implementation Planning

## Shared project skill-context

Before mode routing or work, read existing files relative to the current project root in this order (reuse them if already loaded):

1. `.ai-factory/skill-context/global-skill-context.md`, all bundled skills.
2. `.ai-factory/skill-context/build-skill-context.md`, only fix, implement, plan, verify, improve.
3. `.ai-factory/skill-context/aif-plan/SKILL.md`, this skill.

Missing files are skipped; an existing unreadable file stops dependent work with its path.
Precedence: individual > build (when applicable) > global > skill defaults; retain non-conflicting instructions and check all outputs against the effective rules.
These layers customize workflow; they do not replace the project's rules/architecture hierarchy or relax explicit requirements, ownership, scope, safety/privacy, validation, or approval boundaries. Report conflicts with those boundaries instead of overriding them.
`global` is a project-local layer, not home-directory configuration. Custom/extension skills do not automatically use it.

Create an implementation plan for a feature or task. Three modes:

- **Fast**, quick plan, no git branch, saves to the configured fast plan path (default: `.ai-factory/PLAN.md`)
- **Full**, richer plan, asks preferences, saves to the configured full-plan directory, and optionally creates a git branch/worktree when git is enabled and branch creation is allowed
- **Ultra**, exhaustive multi-file plan bundle under the configured full-plan directory: `index.md` is the manifest/progress ledger and every implementation phase is a separate, deeply specified markdown file. Use it when planning with a stronger model for later execution by a smaller model.

For ultra layout, detail requirements, integrity checks, and consumer behavior,
read `references/ULTRA-FORMAT.md` before creating or modifying the bundle.

## Runtime-aware questions

Apply this contract whenever the workflow asks the user to decide:
