This paper describes the agentTool Process Editor (APE), an Eclipse plug-in based on the Eclipse Process Framework. The aim of APE is to facilitate the design, verification, and management of custom agent-oriented software development processes. APE provides five basic structures. The Library is a repository of agent-oriented method fragments. A Process Editor allows the management of tailored processes. Task Constraints help process engineers specify guidelines to constrain how tasks can be assembled, while a Process Consistency mechanism verifies the consistency of tailored processes against those constraints. Finally, the Process Management integrates APE with the agentTool III development environment and provides a way to measure project progress using Earned Value Analysis.
