Pull request overview
This PR introduces a new Claude plugin, junior-dev, under Claude/plugins/junior-dev/, bundling a research → plan → implement workflow into an installable unit with its own agents, skills, and plugin manifest.
Changes:
- Added a plugin manifest (
.claude-plugin/plugin.json) wiring commands and agents for the workflow. - Added four workflow agents (orchestrator, researcher, planner, implementer) with model tiering.
- Added three workflow skills (research/plan/implement) defining the process expectations for each phase.

- In the
research.md Schemaexample, the markdown table uses||prefixes (e.g.,|| File | Role |), which is not valid table syntax and will likely be copied verbatim into outputs. Update the example to standard markdown table formatting (| File | Role |,| --- | --- |, etc.) to avoid generating malformed research files.

- This constraint conflicts with the implement skill’s rule that says to create missing referenced files (implement skill: “If a task's file references do not exist, create them”). Here the implementer says to stop and report when encountering a missing file. Clarify/align the behavior so the implementer doesn’t receive contradictory instructions (e.g., only stop for missing dependencies not referenced by the plan, but allow creating files explicitly listed in the task’s
Files:section).
## Constraints
- Implement exactly what the plan specifies — do not add, remove, or change scope
- Follow all patterns and conventions referenced in each task's context
- If you encounter something the plan did not anticipate (a missing file, an import conflict, an unexpected dependency), stop and report it to the user before continuing — do not improvise a solution
