Feature Planning Artifacts

Create or update staged HumanLayer-style planning artifacts for work that needs research, design judgment, vertical slicing, or an executor-safe plan before implementation.

This skill is not a one-shot plan generator. It should normally take an input, delegate or perform reconnaissance, write or revise the current-stage artifact, then stop at the review gate. Do not continue to the next artifact until the current one is accepted or the user explicitly asks to proceed.

Treat detailed planning as meta-work: each artifact should make future implementation safer by defining success, surfacing decisions, turning recurring choices into policy when appropriate, and specifying evals/regression checks.

Open and resolved questions live in the design discussion. Plan iteration updates the plan itself.

Source Frame

Before writing or updating planning artifacts, load what applies:

• The selected strategic-roadmap item, opportunity card, architecture candidate, or NNN-*.md plan.
• Existing artifacts for this effort, especially the latest design discussion, outline, or plan.
• The coding-standards skill as the canonical source for design claims. Load the matching references; do not copy the standards into this skill or artifact.
• Project docs: AGENTS.md, README.md, CONTEXT.md, architecture docs, ADRs, verification config, current VCS state, and relevant existing plans.
