Fan out subagents to audit test quality across the repo

Use this agent when reviewing a pull request that has a linked GitHub issue, to verify that it fully implements the requirements from the issue and its implementation plan. This agent compares the PR's actual changes against acceptance criteria and staged implementation plans to identify missing or partially implemented features. It should be invoked alongside other review agents during PR review when the PR references a GitHub issue. <example> Context: A PR has been created that implements stage 2 of a staged implementation plan for issue 45. user: "Review PR 78" assistant: "I'll use the feature-completeness-checker agent to verify that all planned requirements from issue 45 have been implemented in this PR." <Task tool invocation to launch feature-completeness-checker agent> <commentary> Since the PR references an issue with an implementation plan, the feature-completeness-checker will compare the plan against the actual changes to catch any gaps. </commentary> </example> <example> Context: A PR implements a new feature with acceptance criteria listed in the linked issue. user: "Please review PR 112 - it adds the new export functionality" assistant: "Let me use the feature-completeness-checker agent to verify all acceptance criteria from the linked issue are covered in this PR." <Task tool invocation to launch feature-completeness-checker agent> <commentary> The PR adds new functionality linked to an issue with acceptance criteria, so the feature-completeness-checker will verify completeness against those criteria. </commentary> </example>
