t3 · Using Coding Agents

AutoMigrate

A multi-agent pipeline that modernises a real legacy codebase - CommonJS to TypeScript and ESM, or Python 2-style to modern Python 3 with type hints - with minimal manual intervention.

0/0

Modernise a real legacy codebase with a multi-agent pipeline, moving from hand-held single-file edits to an orchestrated planner/implementer/reviewer loop. The skill being built is not prompting - it is knowing what may safely be delegated, and building the verifiers that make delegation safe.

Phases
p1

Foundation: scoped, spec-driven single-agent tasks

Migrate three files by hand-steering an agent, and learn precisely where it goes wrong by recording every intervention.

[0/6]20–30h
p2

Applied: verification loops and autonomous iteration

Build the verifiers first, then let the agent iterate against them without you in the loop.

[0/6]24–34h
p3

Advanced: multi-agent orchestration

A planner/implementer/reviewer pipeline you could point at a different codebase and reasonably expect to work.
