AI Analysis

●●SolidShip ItSolve My ProblemBig Brain

Spec generator that asks the right UX questions AI assistants miss—error states, offline, empty, stale paths.

Strengths

•Includes edge-case UX states (error, offline, stale, empty) that template-based prompts routinely miss, reducing back-and-forth iterations
•Right-sized architecture tiers (minimal/standard/full) default to free tier constraints, showing genuine awareness of budget reality
•Client-side generation (no LLM, pure logic) means zero data collection and instant specs—faster than waiting for API calls

Weaknesses

•Competes directly against existing prompt-engineering culture; many developers already iterate specs via Claude directly with little friction
•No evidence that generated specs actually reduce AI assistant questions or improve build outcomes vs. hand-prompt workflows

Post Description

Generates the parts of a spec you wouldn't think to prompt for -- UX states beyond the happy path (error, offline, stale, empty), content security policy per data source variant, mock data shapes, implementation checkpoints so you approve the design before real data gets wired up.

You describe an app idea, answer questions about data sources and scale, pick your hosting. Output is a markdown spec with architecture guidance, trust boundaries, and a pre-ship checklist. Three complexity tiers based on your answers: minimal (plain HTML/CSS/JS, no build tools), standard (static site + optional edge proxy), full (SSG + edge proxy + KV cache + cron). Defaults to Cloudflare free tier but the stack choices are yours.

Spec generation is entirely client-side -- conditionals and templates, no LLM. Built with Astro 5 on Cloudflare Pages + Workers. Follows the same zero-stack pattern it generates specs for.
