Prompt references and teaching repos that help builders turn loose instructions into stricter agent workflows.
Who it helps
- • Founders learning prompt and context patterns
- • Builders converting prompt examples into versioned skills or eval cases
What to compare
- • Educational depth versus copy-paste breadth
- • How clearly examples state context and constraints
- • Whether prompts can become repeatable workflows
Trust checks
- • Do not ship unsupported claims from a prompt
- • Add your own source material and eval cases
- • Treat examples as patterns to adapt
