pi-stretch

cc-stretch — the Claude Code stretchtext plugin — as a pi extension. Replies arrive short; click a linked phrase and it grows right where it stands.

pi install npm:@mikefreno/pi-stretch

• Guide: before_agent_start adds cc-stretch's stretchtext guide to the system prompt as a stretchtext section, so the model writes replies as {{short|long}} stretchtext.
• Inline: a markdown transformer draws each closed stretch as a link on its short form and each open one with a « after it. A click grows the long form in place in the transcript, the view scrolling down with the growth and back up as « shrinks it — until the reader scrolls, which hands the view back to them. Stretches nest, and any reply in the transcript can be read this way, not only the last.
• Streaming: while a reply streams, its stretches show as their short forms.
• Feedback: with the reader's next message, the model is told which stretches they opened since its last reply, so it never assumes they read a long form they did not open. The note is spliced into that request alone, right after the reader's message, and pi restores the transcript once the request is sent: nothing is written to the session, so the history tree, exports and compaction summaries never see it.

Clicks need pi's fullscreen mode (the default tuiMode) and a terminal that draws OSC 8 hyperlinks. pi answers a click on a hyperlink by handing its URL to the TUI's openUrl; the extension wraps that, so its own https://pi-stretch.invalid/… links open and close stretches and every other link still opens in the browser. Where a click cannot land (regular mode, or no hyperlinks), every stretch is drawn open, as cc-stretch does on Claude Code's classic renderer.

Off the terminal: The Nook

The Nook puts every coding agent you run (pi, Claude Code, Codex and more, local or over SSH) in your Mac's notch, on your iPhone and on your Apple Watch, and it reads stretchtext from both pi-stretch and cc-stretch exactly as the terminal does. Stretches open and close on a tap in the Mac's session detail and the iPhone's message view, compact cards and previews show only the short forms, and the watch shows each reply with every stretch open.

parse.ts, grow.ts and guide.ts are cc-stretch's, vendored unchanged; inline.ts writes stretches into pi's markdown. npm test drives the extension against pi-tui's own Markdown; npm run typecheck checks it against the installed pi.
