Yes — Claude Code skills are isolated by filename, so installing both is safe. They only conflict if they share the same trigger phrase, which is rare. Read each SKILL.md before installing to confirm the trigger patterns don't collide.

Are these skills free?

Yes — every skill listed on ClaudSkills is free to install. The catalog itself is published under CC BY 4.0; per-skill SKILL.md license is set by the original author. Check each skill page's Attribution section for the upstream license.

expect vs scope-appropriate-architecture

Q: What's the difference between expect and scope-appropriate-architecture?

Both are Claude Code skills in the Engineering category. expect: Diff-aware AI browser testing — analyzes git changes, generates targeted test plans, and executes them via agent-browser (Rust daemon + CDP, ARIA-tree-first). Reads git diff to determine what changed, maps changes to… scope-appropriate-architecture: Right-sizes architecture to project scope. Prevents over-engineering by classifying projects into 6 tiers and constraining pattern choices accordingly. Use when designing architecture, selecting patterns, or when… Compare the side-by-side metadata and sample code on this page to pick the right one for your workflow.

Two Engineering Claude Code skills, side by side. Pick the right skill for your workflow with a side-by-side look at metadata, sample code, and install commands.

Sample code from each SKILL.md

expect

/ork:expect                              # Auto-detect changes, test affected pages
/ork:expect -m "test the checkout flow"  # Specific instruction
/ork:expect --flow login                 # Replay a saved test flow
/ork:expect --target branch              # Test all changes on current branch vs main
/ork:expect -y                           # Skip plan review, run immediately

scope-appropriate-architecture

Tier 2 (Prototype) → Tier 3 (MVP)
  Add: Postgres, basic auth, error boundaries, CI

Tier 3 (MVP) → Tier 4 (Growth)
  Add: Redis cache, background jobs, monitoring, module boundaries

Tier 4 (Growth) → Tier 5 (Enterprise)
  Add: DI, bounded contexts, message queues, full observability
  Extract: First microservice (only the proven bottleneck)

Both are free to install. If you're unsure, install both — Claude Code skills are isolated by filename and only collide if their trigger phrases overlap (rare). The richest signal is the SKILL.md body itself — open both skill pages and read the first paragraph of each.
