Walks through discovery, type selection, and configuration with detailed guidance and examples for each skill type. </purpose>

<output>
  A complete skill directory at .vera/skills/{skill_id}/ containing:
  - skill.yaml (vera-cli artifact descriptor)
  - head.md (the `--- name/description ---` frontmatter that surfaces in
    OpenCode's skill picker)
  - skill-overview.md (the workflow-engine-consumed body with overview,
    workflow steps, completion)
  - references/steps/step-NN-*.xml files (one per workflow step)
  - references/{additional}.md (skill-local references such as severity
    ladders, dispatch tables, format specs)
  - references/scripts/*.py (PEP 723 self-contained scripts when needed)
</output>

<key-responsibility>
  Two critical decisions shape every skill:

  1. SKILL TYPE — Determines structure and interaction:
     - workflow: Multi-step, checkpoint-driven, produces output
       incrementally. Has step files under references/steps/.
     - exec: Single-shot execution, returns result. No step files.
     - data: Reference material loaded on demand. No workflow,
       no scripts. Examples in dubstack: context-md-format,
       decision-record-format.

  2. SCRIPTS — Apply script-first mentality:
     If anything CAN be a script, it probably SHOULD be a script.
     Scripts are deterministic, token-efficient, and reliably
     repeatable. Dubstack scripts use PEP 723 inline metadata so they
     are self-contained — agents invoke them via `uv run`.

  Authoring discipline: references carry OPERATIONAL DATA only, not
  meta-commentary. No "this reference is consumed by skill X" intros.
  No "per Lock N" attributions on every sub-statement. No "What this
  table is NOT" meta-sections. Skill prompts carry intent; references
  carry data.
</key-responsibility>

</overview> <workflow>

<step n="1" title="Discovery and Context">
  <action>Load and execute: references/steps/step-01-discovery.xml</action>
  <note>
    Gather requirements: what the skill does, which agent owns it, and
    whether there's a workflow spec (e.g., a ticketsmith / codesmith
    lock) the skill must conform to.
  </note>
</step>

<step n="2" title="Skill Type and Architecture" critical="true">
  <action>Load and execute: references/steps/step-02-type.xml</action>
  <note>
    THIS IS THE MOST CRITICAL STEP. Decisions made here:
    - Skill type (workflow / exec / data)
    - Script-first analysis (what SHOULD be scripts)
    - Script designs (name, purpose, inputs, outputs)
    - Reusable content plan (scripts, references, attachments)
  </note>
</step>

<step n="3" title="Scaffold Skill">
  <action>Load and execute: references/steps/step-03-scaffold.xml</action>
  <note>
    Create the skill directory and initial files following the dubstack
    layout. For workflow skills: skill.yaml + head.md + skill-overview.md
    + references/steps/. For exec: skill.yaml + head.md + skill-overview.md.
    For data: skill.yaml + SKILL.md (flat layout — see context-md-format).
    If shared/workflow-engine.md is missing in the project and the new
    skill is type=workflow, copy from bundled reference.
  </note>
</step>

<step n="4" title="Skill Identity">
  <action>Load and execute: references/steps/step-04-identity.xml</action>
  <note>
    Define name and description in head.md. The description is critical
    for discoverability — it helps the orchestrating agent know when to
    invoke this skill. Be specific about inputs, outputs, and the
    decision shape the skill resolves.
  </note>
</step>

<step n="5" title="Build Configuration">
  <action>Load and execute: references/steps/step-05-build-config.xml</action>
  <note>
    Configure skill.yaml: type/id/destination/file_name, includes
    (head.md + shared/workflow-engine.md + skill-overview.md for
    workflow skills; head.md + skill-overview.md for exec; SKILL.md
    for data), attachments (references/ for skill-local resources;
    shared/scripts/ if the skill invokes any shared script;
    shared/references/{namespace}/ for any cross-skill reference).
  </note>
</step>

<step n="6" title="Create Scripts" if="scripts_planned">
  <action>Load and execute: references/steps/step-06-create-scripts.xml</action>
  <note>
    Generate script files based on designs from Step 2. Each script
    gets PEP 723 header, docstring, and function stubs. Dubstack
    convention: scripts that are reusable across skills live in
    .vera/shared/scripts/; skill-local scripts live at
    references/scripts/. Both invoke `thoughts` CLI internally rather
    than asking the agent to pass thoughts metadata.
  </note>
</step>

<step n="7" title="Workflow Design" if="skill_type == 'workflow'">
  <action>Load and execute: references/steps/step-07-workflow-design.xml</action>
  <note>
    Design the workflow steps. Only for workflow-type skills. This is
    where we plan the user journey through the skill. Each step should
    have a clear purpose and produce a visible artifact or transition.
  </note>
</step>

<step n="8" title="Create Step Files" if="skill_type == 'workflow'">
  <action>Load and execute: references/steps/step-08-step-files.xml</action>
  <note>
    Generate the individual step files under references/steps/. Each
    step file uses the workflow-engine tag vocabulary (action, check,
    ask, invoke-skill, invoke-agent, template-output, goto). Follow the
    ticketsmith / codesmith step-file conventions for cross-skill
    consistency.
  </note>
</step>

<step n="9" title="Validate and Complete">
  <action>Load and execute: references/steps/step-09-validate.xml</action>
  <note>
    Run validation on the completed files. Verify skill.yaml includes
    resolve. Verify step files reference real action types. Update the
    relevant build group in .vera/vera.manifest.yaml.
  </note>
</step>

</workflow> <completion> <action> After all steps complete, present the user with: 1. Location of the created skill files under .vera/skills/{skill_id}/ 2. Summary of the skill's type and structure 3. Manifest update status 4. Next steps: build, test, add to agent menu </action>

<next-steps>
  <step>Build dubstack: `vera build`</step>
  <step>Add skill to the owning agent's frontmatter.md permission map and agent-body.md menu</step>
  <step>Test by invoking from the agent</step>
</next-steps>

</completion> </skill>
