# Build Phase Implement the next incomplete phase of a plan — one phase per invocation. **Context window**: recommend `/clear` before starting to maximize token budget. **Interactive prompts**: present options as a numbered list and wait for the user's choice. ## Input The argument (if provided) is: $ARGUMENTS Use argument as `<slug>`. If empty, list plans as numbered options and wait for the user's choice. Accepts slug or `@file` reference: ``` /tk:build dark-mode-support /tk:build @.tracerkit/plans/dark-mode-support.md ``` If argument starts with `@`, treat it as a file path — read that file directly as the plan. ## Workflow ### 1. Load the plan Read `.tracerkit/plans/<slug>.md`. If missing, list plans as numbered options and wait for the user's choice. ### 2. Find the next incomplete phase Scan the plan for `## Phase N` headings. For each phase, count `- [ ]` and `- [x]` checkboxes. The **next incomplete phase** is the first phase that has at least one unchecked `- [ ]` item. If all phases are complete (zero unchecked items across all phases): > All phases complete. Run `/tk:check <slug>` to verify. Stop here. ### 3. Present the phase Show the phase title and its unchecked items: ``` Phase N — <title> (M remaining) - [ ] First unchecked item - [ ] Second unchecked item ``` ### 4. Offer a feature branch If on the default branch (main/master), ask: > Create branch `feat/<slug>`? > > 1. Yes, create branch (Recommended) > 2. No, stay on current branch
