I'm a contractor (AWS and web apps), so I get a lot of sometimes-ambiguous requests. I have a five-part workflow via Claude/Codex skills: discovery->implementation planning->implementation->verification->review

Each phase writes to `./.agents/plans/{plan-name}/` in the project root. All in Markdown. That way, the flow is agent-agnostic. Each phase artifact is immutable after being written.

More details:

First, I put all the information that I have (documents, client statements, any code, my own summary, etc.) into a document. Which I pass to the discovery planning skill.

The discovery phase more formally defines the project in terms of functional requirements, non-functional requirements, constraints, risks, and assumptions. This might take a few passes to get everything nailed down.

After that, I being a implementation planning phase using the discovery artifact (`discovery.md`). We define the work in terms of phases, where each phases has various tasks associated with it (all checkboxes). Again, usually requires a few passes.

After that, I have a clear idea of the work needed and can send an estimate to the client. Or, if it's a personal project, get started actually building it. I have another phase for actual implementation.

Verification and review are similarly defined. They can be done by any agent.
