Tip

Click the link under each diagram to open it on a canvas you can zoom, pan and step through

🪧 More tips

• Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
• Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists
• Untick Architecture lens or Data flow lens under View to hide a diagram, or tick Expand every detail to open every section. The comment redraws in a few seconds
• The diagrams are links. Click one to open it on the canvas, then press W or click play to walk through the change
• Open a diagram on the canvas, then press W or click play to walk through the change one step at a time
• The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
• Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs on every push
• Set github.draw: on-demand in .github/pr-lens.yml and PR Lens stops drawing every push. Comment @pr-lens draw on a pull request when you want that one drawn
• Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works
• Push a commit and the comment redraws for the new head. A slow older run never overwrites a newer one
• Switch GitHub to dark mode and the diagrams follow. The moving dots are this pull request's data in motion
