TypeScript Strict Mode

TypeScript Strict Mode is an agent skill that teaches any connected AI model how to write and review TypeScript under the strictest compiler settings — strictNullChecks, noImplicitAny, strictFunctionTypes, and the rest of the strict family enabled together. Rather than producing code that merely compiles, the skill encodes patterns for generics, conditional types, mapped and utility types (Partial, Pick, Record, Omit, and custom variants), and discriminated unions so that agents generate type-safe APIs, hooks, and data models instead of loosely typed shims. It's built for teams who treat TypeScript strict mode as a non-negotiable baseline and want every agent — Claude, GPT, or Gemini — to honor that baseline consistently, whether it's scaffolding a new module, refactoring a legacy file, or reviewing a pull request.

On BusinessMCP.com, this skill is connected once to your hosted MCP server and then becomes available to every AI agent your teams already use, through a single /api/mcp endpoint secured with a Bearer mcph_* key. That means your coding agents, internal tooling, and any custom integrations all draw from the same TypeScript strict-mode logic instead of each maintaining its own drifted interpretation of "strict." Because BusinessMCP is model-agnostic, you're not locked into a single vendor's coding assistant — swap or mix Claude, GPT, or Gemini behind the same endpoint and the strict-mode conventions travel with the request, not the model.

Typical use is during active development: an agent asked to add a new API route can use the skill to infer generic response types and avoid `any`; an agent refactoring an older service can apply conditional types to narrow union-heavy code paths; a reviewer agent can flag places where strict null checks are silently bypassed with non-null assertions. The skill is equally useful for onboarding — new contributors (human or AI) inherit the same type-safe API conventions without a written style guide, and generated utility types stay consistent with how the rest of the codebase already models data.

Because it lives inside BusinessMCP's unified MCP layer, TypeScript Strict Mode sits alongside your other developer-tools skills and your business-intelligence dashboard rather than as an isolated plugin. Pairing it with framework-specific skills (for React or Next.js components, Prisma models, or Supabase queries) lets agents apply strict typing across the full stack — from database schema to UI props — while your BI dashboard gives visibility into how these skills are actually being invoked across teams. Add a git workflow or TDD skill on top and agents can generate strictly typed code, test it, and commit it through the same governed, cookieless, GDPR-friendly pipeline, with one Bearer key controlling access instead of scattered API credentials per tool.

For engineering leads standardizing on strict TypeScript, this skill removes the repetitive correction cycle where agents produce loosely typed code that then needs manual tightening. Instead, generic constraints, conditional type narrowing, and utility-type composition are baked into how the agent reasons about the problem from the first draft, which is especially valuable in larger codebases where type-safe APIs at module boundaries prevent cascading `any` leakage into consumers.
