SpecShip
A spec-driven autonomous engineering workflow, packaged as a Kiro Power, that walks an AI coding agent through reverse-engineering existing code, planning, test-driven building, adversarial validation and shipping a pull request.
SpecShip runs AI agents through four phases plus an optional brownfield recon step. Recon reverse-engineers existing code into a repo map, stack, components, APIs, data models and business flows before planning begins; Plan brainstorms, does real web research, writes a sprint contract, pre-generates test cases and produces requirements, design and task documents; Build executes the task list milestone by milestone in parallel batches, following a write-failing-test-then-implement cycle with a hard gate that blocks a milestone until typechecking, tests and the build all pass.
Validate runs up to seven adversarial validators in parallel as independent subagents covering code, security, integration, browser, design, alignment and, when a performance requirement exists, load, each producing a typed verdict that is aggregated into a decision to merge, recover or escalate; Ship produces a pull request, changelog and archive with a report of timing, bugs caught and milestone breakdown, or prepares the change locally with push instructions if there is no git remote.
