sdd-steering

name	sdd-steering
description	Creates or updates reusable project steering documents in .ai/steering for product context, tech stack, conventions, and domain-specific guidance. Use when shared AI context needs to be established or corrected, but confirm before saving durable/global steering changes. Do not use for feature-level requirements or implementation.

AI Steering

Create or update reusable project context in .ai/steering/.

Purpose

Steering documents capture stable project guidance that many skills can reuse. They are not SDD feature artifacts; they describe the broader product, stack, principles, conventions, and domain rules that should guide IDEA, PLAN, PRD, SPEC, TASKS, EXEC, REVIEW, and other AI workflows. Because steering is durable project-wide context, draft freely but confirm before saving or changing global guidance.

Workflow

1. Load references.

   • Read ../_shared/references/sdd-practical.md.
   • Apply the Language Policy: respond and write artifacts in the user's initial chat language while keeping skill instructions and templates in EN-US.
   • Read ../_shared/references/templates.md when drafting artifacts.
   • Use package-level templates/steering-*.md files as user-facing examples when available.

2. Establish the steering workspace.

   • Use .ai/steering/.
   • Create .ai/steering/ if it does not exist.
   • Read existing .ai/steering/*.md before changing them.
   • Briefly inspect project README, package files, docs, and source tree when useful.

3. Determine which steering docs are needed.

   • product.md for product vision, users, value, boundaries, success metrics, glossary.
   • tech-stack.md for runtime, frameworks, libraries, infrastructure, verification commands, constraints.
   • conventions.md for code style, architecture patterns, naming, testing, accessibility/security, workflow.
   • principles.md for project principles, MUST/SHOULD rules, decision rules, review expectations, and governance-like guidance.
   • Domain-specific docs such as lp.md, payments.md, brand.md, or content.md when the user wants reusable guidance for a specific workflow.

4. Clarify missing context.

   • Ask one question at a time.
   • Prefer multiple-choice questions when useful.
   • Do not over-interrogate; use existing project evidence when reliable.
   • Mark uncertain items as Open Questions rather than inventing durable rules.

5. Draft or update steering.

   • Use the Steering Templates from ../_shared/references/templates.md.
   • Keep docs concise and stable.
   • Separate facts from preferences and open questions.
   • For principles.md, prefer practical MUST, SHOULD, and MAY rules over legalistic language such as "constitution".
   • For principles.md, help non-technical users choose principles with guided options and examples instead of asking broad governance questions.
   • Do not duplicate feature-level requirements from .ai/sdd/specs/.

6. Review with the user.

   • Present the proposed steering content or diff summary.
   • Ask for explicit approval before writing or overwriting durable steering docs.
   • If updating existing files, preserve useful existing content.

7. Save.

   • Save approved docs under .ai/steering/.
   • Recommend next SDD action if relevant, such as /skill:sdd-idea, /skill:sdd-plan, or /skill:sdd-prd.

Output

Common outputs:

• .ai/steering/product.md
• .ai/steering/tech-stack.md
• .ai/steering/conventions.md
• .ai/steering/principles.md
• Optional .ai/steering/<domain>.md

Quality Bar

• Steering must be reusable across features and skills.
• Steering must be concise enough to remain useful as context.
• Stack and verification commands should be based on actual project files when possible.
• Conventions should describe existing patterns, not aspirational rewrites, unless the user explicitly approves a new convention.
• Principles should be stable, actionable, and easy to evaluate during PRD, SPEC, TASKS, EXEC, and REVIEW.
• Open Questions should remain visible instead of being guessed.

Critical Rules

• Do not write feature-specific requirements, design, tasks, or implementation code in this skill.
• Do not overwrite existing steering without reviewing it first.
• Do not invent project facts that are not provided by the user or repository evidence.
• Do not treat steering as higher priority than explicit user instructions or approved SDD artifacts; surface conflicts and ask.
