🟡 CHANGED Inspect Devframe

Devframe plugin providing inspection UI and tools for inspecting runtime state, functions, and agent manifests.

• plugins/inspect/app/components/AgentView.vue:1-135

View

• Architecture lens
• Data flow lens
• Expand every detail
• Show unchanged neighbours

Tip

Would you rather run it from CI on a key of your own? Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and a model key in your repository secrets, say GEMINI_API_KEY. The Action asks Gemini by default, or OpenAI and any endpoint speaking /chat/completions through its provider input.

🪧 More tips

• Run PR Lens on your own machine: npx skills add coldteadotai/pr-lens installs the agent skill. Then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
• Draw a diff before it is even a pull request: npx @coldtea/pr-lens-cli analyze --base origin/main reads the diff with your own model key, and npx @coldtea/pr-lens-cli render .pr-lens/graph.json draws the same lenses on your machine.
• The boxes under View are live. Tick Architecture lens or Data flow lens to choose which diagrams appear, or Expand every detail to open every drill-down at once. The comment redraws in place a few seconds later.
• Show unchanged neighbours lists the components this change did not touch alongside the ones it did, so the drill-down shows what the changed code sits next to.
• GitHub will not let you zoom an image in a comment. The link under each diagram opens it on an interactive canvas, where you can zoom, pan and step through the flow.
• The CLI's render picks up .github/pr-lens.yml automatically and applies your corrections (renames, exclusions, lane pins) at draw time.
• PR Lens is free for open source. A star on the repository is what keeps it going.
• Push a new commit and the whole comment re-renders for the new head. An older run never overwrites a newer one, so a slow render cannot put a stale diagram back.
• The diagrams follow your GitHub theme, so dark mode gets the dark render and light mode the light one, and the moving dots show this pull request's data in motion.

🟡 Changes recommended

The new error element id generation is based on a lossy tool-name transform and can create duplicate DOM ids, breaking the intended aria-describedby association.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR improves the Inspect devframe’s Agent tab by surfacing malformed JSON argument parsing errors inline, tying them to the arguments textarea for accessibility, and clearing the error state on edits or successful parses.

Changes:

• Added per-tool parsing error state (invokeErrors) and changed invocation to report JSON parse failures inline instead of throwing.
• Improved textarea accessibility with aria-invalid and aria-describedby, and added an inline error alert UI via FeedbackTip.

Actually, we could redo this view completely with better async state handling, filters, auto discovery of values, etc
