How does this skill prevent rework compared to standard AI coding prompts?

This skill acts as a mandatory checkpoint that prevents your AI agent from writing code until the architecture is approved. It solves the problem of 'scope drift' and wasted compute time by forcing a structured design phase, uncovering hidden constraints before implementation begins.

Is this skill compatible with my specific tech stack or frontend framework?

The skill is platform-agnostic and works with any programming language or framework. It generates standard Markdown documentation and Mermaid.js diagrams, ensuring your design specs are readable by both humans and other AI planning tools.

What exactly is included in my purchase?

You receive the full Concept Exploration & Design Gate skill definition, ready to be imported into your AI agent's environment. It includes the logic for the multi-stage discovery loop, design template structures, and the automated documentation workflow.

Does this skill generate the final source code after I approve the design?

No, this is a dedicated 'design gate' focused on alignment and architecture. Once a design is approved and committed to your repo, you should hand the resulting specs over to an implementation-focused skill like 'writing-plans' or a standard coding agent.

What is the setup process like for integrating this into my existing workflow?

Setup is minimal; once added to your agent's library, you simply trigger it when starting a new feature. It automatically begins by scanning your current codebase and recent commits to ensure any new design exploration is contextually aware of your existing architecture.

Concept Exploration & Design Gate

Example session with this skill installed

I want to add a bulk invoice export feature to our billing app (Rails 7, Postgres, in /home/me/billing). Customers keep asking to download invoices as PDF and CSV, and I imagine an Export button on the invoices page. The repo has a README, some half-finished reports code, and recent commits around payment webhooks. Before anyone writes code, run the full concept exploration on this: inspect the project context, interview me one question at a time about what actually matters, compare the realistic approaches with trade-offs and a recommendation, get my sign-off section by section, write the final design doc under docs/designs/, and then move into implementation planning.

Compiled the concept exploration

Summary

Concept exploration for the bulk invoice export feature is complete. Requirements were locked through six sequential questions, three approaches were compared, and the approved design is committed to docs/designs/2026-09-14-invoice-export.md. No code was written — implementation is ready to plan.

Item	Before	After
Scope	'add PDF export'	CSV + PDF, up to 10k rows, async job
Open questions	7 unresolved	0 — all answered
Approaches	none	3 compared, 1 recommended
Design record	none	docs/designs/2026-09-14-invoice-export.md (commit a41f9c2)

Key decisions

Async background job chosen over synchronous download: p95 for 10k rows exceeds request timeout
Reuses the existing ReportService queue instead of introducing Celery
YAGNI: email-delivery option dropped; users download from the UI

Next steps

Invoke writing-plans to convert the approved design into a phased roadmap
Review the committed design doc before the plan starts
Revisit success criteria (export under 45s per 1k rows) at acceptance testing

About this skill

Stop wasting hours on rework caused by misunderstood requirements and scope drift. This skill enforces a design-first workflow, ensuring every feature, refactor, or component is fully architected and approved before a single line of code is written. It transforms vague requests into structured technical documentation through systematic inquiry.

What it does

Intent clarification by asking sequential, focused questions to uncover hidden constraints and success criteria.
Approach exploration by generating 2-3 distinct solution paths with analyzed trade-offs and expert recommendations.
Incremental validation through section-by-section design presentations that require explicit user sign-off.
Automated documentation by generating and committing design specs to docs/designs/ for permanent record.
Implementation handoff by preparing the context needed to transition directly into detailed planning skills.

How it works

Context discovery scans your current codebase and recent commits to understand the existing state.
Clarification loops use structured, often multiple-choice questions to define the "why" and "what" without ambiguity.
Design drafting presents the architecture, data flow, and error handling for your review.
Final approval triggers the creation of a dated design markdown file and its commit to your repository.

Frameworks & tools

This skill is platform-agnostic and works with any tech stack. It utilizes Mermaid.js for flowcharts and follows YAGNI principles to ensure lean architecture.

Why this beats prompting it yourself

Generic prompts often jump straight to code, missing edge cases and integration impacts. This skill enforces a strict gate, preventing the AI from "hallucinating" an implementation plan before you have agreed on the fundamental architecture.

Use cases

Defining the architecture for a new microservice or API endpoint.
Mapping out complex state management changes in a frontend application.
Evaluating trade-offs between different third-party library integrations.
Establishing a shared source of truth for a feature before team execution.

Known limitations

Does not perform the actual coding or implementation; it is strictly a design and alignment gate. Requires the writing-plans skill for the subsequent implementation roadmap.
