The Builder's Stack
Prompt → Agent → Eval. All three products, fully integrated. Save $38 vs. buying separately.
**Prompt → Agent → Eval. The three primitives every AI builder ships.**
The Builder's Stack is all three of our products — Prompt Foundry, Agent Blueprints, and Eval Kit — packaged together with an onboarding walkthrough that wires them end-to-end.
Individual sum: $167. Bundle: **$129** (save $38). One-time purchase. Commercial license. Lifetime updates on every product (v1.1 of each is free).
The story behind it
## Why these three, together
The stack is designed for integration:
- **Prompt Foundry** ships 32 XML-tagged prompts, each with a `.jsonl` of golden eval cases. - **Agent Blueprints** ships 6 production agents whose system prompts follow the Foundry conventions and whose eval sets follow the same `.jsonl` shape. - **Eval Kit** auto-discovers both. Drop the `evals/` directories in; everything runs through one CI workflow.
You can wire the entire prompt → agent → eval pipeline in one Friday afternoon. The Stack Onboarding walkthrough script (delivered now, video to follow) shows you exactly how.
