Review an existing functional design against its modeling Spec and canonical quality Rule before technical design begins. Evaluative atomic skill; outputs findings without rewriting.

The file

We split this skill into the rules it gives an agent

10 rules. About 0 are common, 10 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈10

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Skill: Review Functional Design

Purpose

Evaluate an existing functional design against functional-design-modeling and functional-design-quality. This is a pre-coding business-behavior gate, not an architecture review and not a meta-skill.

Core objective

Determine whether business modules, workflows, states, permissions, exceptions and acceptance criteria are complete and traceable enough for technical design.

Scope boundaries

This Skill reviews one functional-design artifact and its requirement references. It does not create the design, make technical choices, review implementation or aggregate other Skills.

Use cases

  • After functional design is drafted and before technical design
  • After business workflow, state or permission changes
  • Before accepting a functional design imported from another system

Behavior

  1. Load the active modeling Spec and quality Rule.
  2. Verify artifact identity, approved parent, required sections and all conditional sections, including UI and interaction flow, against the loaded Spec and Rule. A sufficient existing design needs no external reference. Use the UI design decisions guide for reference evidence and handoff context.
  3. Check workflow closure, exception behavior, business boundaries and acceptance traceability without introducing technical implementation detail.
  4. Emit one finding per violation with category functional-design-quality and a precise section or flow/state location.
  5. Report zero findings as ready for technical design, without invoking it.

Input and output

Input is one existing functional-design path or full content. Output follows findings-list.

Restrictions

  • Do not rewrite the design or requirement.
  • Do not demand database, API or deployment detail in this layer.
  • Do not restate business rules that should be cited from the requirement.

Self-Check

  • Both canonical assets were loaded.
  • Conditional state, permission and UI sections were evaluated, including legitimate UI skip reasons.
  • Every finding is grounded and uses category functional-design-quality.
  • No technical-design criterion was introduced.

Examples

Example 1: approval roles differ

If two roles have different operation permissions and no permission matrix exists, emit the matching conditional-section finding.

Example 2: purely technical refactor

If the input is an ADR-authorized refactor with no user-visible behavior, stop and redirect to technical design; a functional design is not required.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
