Decide Build Primitive

Analyze, compare, and recommend a Codex build primitive. Use when the user is packaging or automating a workflow and the right primitive is unclear.

Philosophy

• Keep the workflow evidence-first and bounded to the requested scope.
• Prefer the smallest reversible step that proves or disproves the current assumption.
• Preserve user work and repo-native contracts before introducing new machinery.

When To Use

• Deciding between Skill, Custom Prompt, and Agent automation.
• Packaging a repeated workflow.
• Documenting tradeoffs for a durable automation choice.

Avoid

• Unrelated work that belongs to a more specific skill.
• Broad rewrites before the first blocker or decision point is understood.
• Claiming success without command, artifact, or decision evidence.
