How the Proactive Builder Works

TeamLead AI doesn't just tell your team what to do. It does work.

When you create a goal like "Add Stripe checkout flow," the agent:

  1. Reads your codebase to understand the architecture, file patterns, and coding style
  2. Creates a branch (feat/stripe-checkout)
  3. Writes the boilerplate — types, API route skeleton, component structure, database migration
  4. Opens a draft PR with a clear description of what's done and what needs human work
  5. Assigns the right developer with context: "I've set up the Stripe client and types. You need to implement the webhook verification and build the checkout UI."

The developer starts building on a solid foundation instead of from scratch. The boring setup is done. They focus on the business logic.

What It Builds

The agent is good at:

  • Project scaffolding: repo structure, config files, boilerplate
  • Feature skeletons: types, route handlers, component stubs with TODO comments
  • Bug fixes: simple null checks, missing imports, type errors
  • Refactors: rename consistency, code deduplication, import cleanup
  • Tests: test skeletons matching your existing test patterns

What It Never Does

The agent never:

  • Merges to main without human approval
  • Deletes code
  • Changes architecture without asking
  • Modifies business logic
  • Pushes directly to production

Everything goes through a PR. Humans always have the final say.

Style Matching

The agent analyzes your existing code to match your style:

  • File naming conventions (kebab-case, camelCase, PascalCase)
  • Import patterns (relative, aliased, barrel exports)
  • Test patterns (.test.ts, .spec.ts, __tests__/)
  • Component patterns (functional, hooks, composition)

Generated code looks like your code, not generic boilerplate.
