create-app

Guided journey from a raw app idea to a validated, cleanly architected first version that ships on a sustainable cadence. Orchestrates ten skills phase by phase - lean-startup, design-sprint, clean-architecture, domain-driven-design, clean-code, pragmatic-programmer, system-design, ios-hig-design, 37signals-way, software-design-philosophy - asking the user questions at every decision point and recording results in the project docs/ folder (PRODUCT.md, ARCHITECTURE.md, EXPERIMENTS.md, CREATE-APP-PLAN.md) so the journey resumes across sessions. Use when the user wants to build a new app, validate an idea before writing code, architect an MVP that will not need a rewrite, or says 'help me build my app the right way'. App already exists: use improve-app or grow-app. Business idea not yet validated: run create-business first. Marketing site only: use create-website. Architecture-only question: design-code-architecture. For one framework in isolation, invoke that skill directly.

Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured orchestrator body that sequences ten phases with concrete artifacts, explicit validation checkpoints, and a real one-level-deep reference for templates. Its only weakness is mild over-explanation in the per-phase methodology fallbacks.

Suggestions

Tighten the per-phase Brief fallbacks: distill each to the few non-obvious rules Claude would not already know, since the named constituent skills are expected to carry the full method.

Consider moving the longer methodology fallbacks (e.g. Phase 7 capacity math, Phase 8 HIG detail) into references/ so the SKILL.md body stays a lean overview.

Confirm the Briefs are explicitly framed as fallback-only so it is clear they are the minimum viable method, not the primary path.

DimensionReasoningScore

Conciseness

Mostly efficient with no generic concept padding, but the per-phase Brief fallbacks re-summarize methodology Claude largely already knows (lean-startup, clean-architecture, DDD, HIG, 37signals) at a length that could be trimmed without losing the fallback value.

4 / 5

Actionability

Highly concrete and actionable for an instruction-only skill: every phase specifies exact docs files, section headings (e.g. "Create docs/PRODUCT.md with `## Vision` and `## MVP Definition`"), tracker statuses, decision points, and a "Done when" criterion.

5 / 5

Workflow Clarity

Clear ten-phase sequence (Journey Map table plus numbered phases) with explicit validation checkpoints — sign-off before writing artifacts, the `awaiting-evidence` feedback loop, and a closing exit checklist — providing the feedback loops the rubric rewards.

5 / 5

Progressive Disclosure

SKILL.md is a well-organized overview with a single well-signaled, one-level-deep reference ([references/artifact-templates.md]) that actually exists in the bundle, with content appropriately split out of the main file.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly states what the skill does, when to use it via concrete trigger phrases, and how it differs from sibling skills. It is comprehensive without padding and names specific artifacts and constituent skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Orchestrates ten skills phase by phase", "asking the user questions at every decision point", "recording results in the project docs/ folder" — and names concrete artifacts (PRODUCT.md, ARCHITECTURE.md, EXPERIMENTS.md, CREATE-APP-PLAN.md), giving comprehensive coverage of what it does.

5 / 5

Completeness

Explicitly answers both what ("Guided journey from a raw app idea to a validated, cleanly architected first version", orchestrating ten skills, recording results) and when ("Use when the user wants to build a new app, validate an idea before writing code, architect an MVP...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural-language triggers users would actually say — "build a new app", "validate an idea before writing code", "architect an MVP that will not need a rewrite", and the direct quote "help me build my app the right way" — plus synonym-style routing variants.

5 / 5

Distinctiveness Conflict Risk

Clear niche (new-app creation via a ten-phase journey) with explicit sibling-skill disambiguation — "App already exists: use improve-app or grow-app", "Business idea not yet validated: run create-business first", "Marketing site only: use create-website", "Architecture-only question: design-code-architecture" — minimizing conflict risk.
