expect vs python-backend

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.

Side-by-side

Sample code from each SKILL.md

/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

When to choose each

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…

python-backend — Production Python async patterns including asyncio TaskGroup, FastAPI dependency injection and middleware, SQLAlchemy 2.0 async sessions, and database connection pool tuning. Python 3.11+ examples with structured error…

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.
