code-plan - SKILL.md Agent Skill

name: code-plan description: "P-phase skill for the codesmith implementation workflow. Converts the structural skeleton into per-slice tactical steps (TDD vertical: failing test → minimal impl → green → verify → commit) per Lock 8. Produces one plan doc per plan identified in D-phase. Runs the Parallel-Safety Evaluation per Lock 27 to determine whether multiple plans execute in parallel worktrees or serialize. Spot-check user review; no open questions in the final plan. Hands off to worktree-setup (or directly to code-implement if Work-Tree is bypassed)."

Execute workflow by following instructions and producing output Always read COMPLETE files - NEVER use offset/limit when reading any workflow related files Instructions are MANDATORY - either as file path, steps or embedded list in YAML, XML or markdown Execute ALL steps in instructions IN EXACT ORDER Save to template output file after EVERY "template-output" tag NEVER skip a step - YOU are responsible for every step's execution without fail or excuse

Steps execute in exact numerical order (1, 2, 3...) unless an explicit goto directs otherwise Optional steps: Ask user unless YOLO mode active Template-output tags: Save content, discuss with the user the section completed, and NEVER proceed until the user indicates to proceed (unless YOLO mode has been activated)

For each step in instructions:

  <substep n="1a" title="Track Progress">
    <action if="first iteration">Create todo list from all instruction step titles (TodoWrite)</action>
    <action>Mark current step as in_progress (TodoWrite)</action>
  </substep>

  <substep n="1b" title="Handle Step Attributes">
    <check>If optional="true" and NOT YOLO -> Use Question tool to ask user whether to include (Yes/Skip)</check>
    <check>If if="condition" -> Evaluate condition</check>
    <check>If for-each="item" -> Repeat step for each item</check>
    <check>If repeat="n" -> Repeat step n times</check>
  </substep>

  <substep n="1c" title="Execute Step Content">
    <action>Process step instructions (markdown or XML tags)</action>
    <action>Replace {{variables}} with values (ask user if unknown)</action>
    <execute-tags>
      <tag>action -> Perform the action</tag>
      <tag>action type="script" -> Execute as shell command, capture output</tag>
      <tag>check if="condition" -> Conditional block wrapping actions (requires closing &lt;/check&gt;)</tag>
      <tag>ask -> Prompt user using Question tool and WAIT for response. When options exist, present them as selectable choices. For open-ended questions, provide helpful suggested options with custom input enabled</tag>
      <tag>invoke-skill name="skill-name" -> Execute another skill via OpenCode skill system</tag>
      <tag>invoke-agent name="subagent" prompt="task" -> Delegate to subagent via Task tool</tag>
      <tag>goto step="x" -> Jump to specified step (used for explicit loop-back in Q-R style flows)</tag>
    </execute-tags>
  </substep>

  <substep n="1d" title="Handle template-output Tags">
    <if tag="template-output">
      <mandate>Generate content for this section</mandate>
      <mandate>Save to file (Write first time, Edit subsequent)</mandate>
      <action>Display generated content</action>
      <action>Use Question tool to present checkpoint options. WAIT for response.
        <options>
          <option label="Continue" description="Approve this section and move to the next step" />
          <option label="Advanced Elicitation" description="Explore this section deeper before proceeding" />
          <option label="YOLO" description="Auto-complete the rest of this workflow without stopping" />
        </options>
        <if response="Advanced Elicitation">
          <action>Invoke advanced-elicitation skill</action>
        </if>
        <if response="Continue">
          <action>Continue to next step</action>
        </if>
        <if response="YOLO">
          <action>Enter YOLO mode for the rest of the workflow</action>
        </if>
      </action>
    </if>
  </substep>

  <substep n="1e" title="Step Completion">
    <action>Mark current step as completed (TodoWrite)</action>
    <check>If no special tags and NOT YOLO:</check>
    <action>Use Question tool to ask:
      <options>
        <option label="Continue" description="Proceed to the next step" />
        <option label="Edit" description="Revise this step before moving on" />
      </options>
    </action>
  </substep>
</step>

<step n="2" title="Completion">
  <check>Confirm all instruction steps have been executed</check>
  <output>Workflow complete.</output>
</step>

Full user interaction and confirmation of EVERY step at EVERY template output - NO EXCEPTIONS except YOLO mode Skip all confirmations and elicitation, minimize prompts and try to produce all of the workflow automatically by simulating the remaining discussions with a simulated expert user

step n="X" goal="..." - Define step with number and goal substep n="Xa" title="..." - Sub-step within a step phase n="X" - Phase within a substep optional="true" - Step can be skipped if="condition" - Conditional execution for-each="collection" - Iterate over items repeat="n" - Repeat n times action - Required action to perform action type="script" - Execute shell command action if="condition" - Single conditional action (inline, no closing tag needed) check if="condition">...</check> - Conditional block wrapping multiple items (closing tag required) ask - Get user input via Question tool (ALWAYS wait for response before continuing). Present defined options as selectable choices. For open-ended questions, offer helpful suggestions with custom input enabled goto - Jump to another step (explicit loop-back) invoke-skill - Call another skill invoke-agent - Delegate to subagent via Task tool invoke-protocol - Execute a reusable protocol (e.g., discover_inputs) template-output - Save content checkpoint critical - Cannot be skipped example - Show example output note - Informational content output - Display to user without saving halt-conditions - Define conditions that MUST stop execution condition - Single halt condition validation - Pre-condition rules to check

- This is the complete workflow execution engine - You MUST follow instructions exactly as written - This workflow uses INTENT-DRIVEN PLANNING - adapt organically to product type and context - YOU ARE FACILITATING A CONVERSATION with a user to produce a final document step by step - The whole process is meant to be collaborative - helping the user flesh out their ideas - Do not rush or optimize and skip any section

Convert structural skeleton into per-slice tactical steps via TDD vertical-slice mandate. Run Parallel-Safety Evaluation. Produce one plan doc per plan from D-phase.

<inputs>
  Session state from code-structure:
  - bundle_dir, ticket_path, ticket_alias, ticket_slug, primary_tag
  - design_path (locked), structure_path (locked)
  - plan_count, slices
</inputs>

<outputs>
  Per plan: plan-YYYY-MM-DD-{ticket_slug}.md OR
  plan-YYYY-MM-DD-{ticket_slug}-plan-{n}.md for multi-plan.

  Each plan doc contains:
    - Per-slice tactical steps (test → impl → green → verify → commit)
    - Dependency ordering between slices
    - Verification commands per slice
    - Commit message convention
    - Parallel-Safety section (in plan-1.md only if multi-plan)
</outputs>

<discipline>
  TDD vertical-slice MANDATE per Lock 8: one test → one impl →
  repeat. NEVER horizontal (all tests then all impl). Horizontal
  slicing produces crap tests that test shape instead of behavior.

  No open questions in the final plan. Spot-check user review only
  (alignment already done in D/S).

Plans are locked. The handoff routes to worktree-setup (for the first plan to execute, per the parallel-safety determination) and then to code-implement.
