Watch Claude Code build a terminal-session sharing tool
Transcript reviewed · recording and outcomes not independently reproduced
What the transcript explains
Simon Willison combines two existing tools into a terminal-to-HTML sharing page with Claude Code for web. He references the repository's rich-text conversion and GitHub Gist authentication implementations, tries a pull-request preview, then checks the published tool in Firefox and Chrome. The recording includes failing tests and a preview-domain authentication limitation rather than a clean one-shot success.
Limits and human checks
- The presenter merges despite failing checks; this review does not recommend that release decision.
- Gist authentication is not fully exercised on the preview domain. Review terminal content for secrets before publishing it.

Suggested prompt
Suggested prompt written by Agents In Use, not the source author. Replace bracketed inputs and review tool permissions first.
Build a local terminal-output viewer from the existing repository parser. Preserve formatting and add a preview. Test RTF, HTML and plain-text inputs. Keep sharing disabled until the user reviews content for secrets and approves the destination.
Steps from the account
- Describe the clipboard-to-HTML workflow and reference existing repository tools.
- Let Claude Code build the new interface and integrate Gist creation.
- Inspect the tool and demonstrate the resulting sharing workflow.
