ChatGPT has 5 tools and zero construction context. Foreman has 396 skills, three memory files, and a 30-chapter manual on Cornerstone PM's data model baked into every conversation.
This is why it actually works.
Every conversation Foreman has starts with all 183KB of this loaded into context. No vector search. No retrieval lag. No “let me look that up” pauses.
Every feature, workflow, role guide, and data model in Cornerstone PM — documented in prose Foreman can reason over. When you say “cascade the schedule when the foundation inspector confirms,”Foreman knows what a cascade is, how scheduling templates work, which webhook fires, and which downstream tasks unlock. It's not guessing — it's reading the manual.
Construction math, baked into the agent. Give Foreman the dimensions and it returns accurate quantities and rough cost — no calculator, no spreadsheet, no“ChatGPT, what's a board-foot again?” detour.
Pre-built setup prompts for the design center. Copy a prompt, swap in your vendor and brand names, hit enter. Foreman builds your entire product catalog — OptionClasses, attribute values, pricing modifiers, tier access — in one conversation turn.
This is what powers the 75-action chain.
Not generated code. Not vibe-driven function calling. Every skill is a typed TypeScript function with input validation, ACL checks, and structured returns — sitting in our codebase waiting to be called.
The knowledge base isn't a marketing flex. It's the reason Foreman can do things other construction AI tools can't.
Generic AI caps at 3–5 tool calls per turn because it drifts after a few steps. Foreman doesn't drift — it knows the system. So we let it run 75.
Skills are typed functions with input validation. The model picks from a menu; it doesn't write SQL. No DELETE FROM homes by accident.
Skills hit Prisma + Postgres directly. No HTTP middleman. 75 calls execute in under 4 seconds. The bottleneck is the model thinking, not the tools running.
396 skills. 20 categories. 24,500 words of construction expertise. 39 estimating formulas. 3 memory files.
One AI that doesn't just talk — it builds.
