Start from the prompt
The preview uses the chosen branch, prompt, attachments, manual file choices, exclusions, and any file references named in the prompt.
Know what the planning model will see.
Bad plans usually start with the wrong context. ProPR shows the files, summaries, screenshots, attachments, and reference repositories that will shape the plan before generation starts, so the team can adjust the input before code changes expose the mistake.
Feature overview
Find likely files
ProPR suggests files that appear relevant; you review and adjust the selection before planning.
Fit the useful context
If the repository is large, ProPR prioritizes the most useful files and warns when the prompt is getting too big for the selected model.
Add supporting material
Add repository summaries, screenshots, attachments, and reference repositories when they help the model understand the task.
Refresh or export
Refresh the preview when inputs change, or export it to inspect exactly what will be sent into planning.
Controls
Change selected files, excluded files, attachments, supporting repositories, and model choice before generation.
Signals
The UI shows included files, warnings, size estimates, cost estimates, and whether the preview needs a refresh.
Large repositories
When a repository is too large to include everything, ProPR keeps the priority paths and leaves lower-value files out.
Reference repositories
Include additional repositories as examples or background without making them the target of the implementation.
Reuse
When the prompt, branch, files, and attachments have not changed, ProPR reuses the existing preview.
Why it matters
Planning errors usually start with wrong context. ProPR makes the context boundary visible in the planning workspace before implementation begins.
