would be great if claude code could watch for github actions / pr comments and reacts automatically (on my local machine) and only pings if decisions are required

Just used Beans for Claude Code for a smallish refactoring - and I quite like it. Simple, markdown files, nice TUI to see what's going on and potentially even edit stuff. Claude Code and the TUI on split screen.

It's so much fun to leave `beans tui` running in a separate window. It'll automatically pick up changes in the filesystem and update itself accordingly.

Beans and Claude are such a great team. Instead of whipping up a plan that will be long forgotten the very next session, just put it into a bean, and it'll stick around until you want to iterate on or implement it.

title: Refactor prompt command to use text/template
status: todo
type: task
created_at: 2025-12-08T20:16:08Z
updated_at: 2025-12-08T20:16:08Z
---
## Summary
Refactor the `beans prompt` generation to use Go's `text/template` package instead of
string builders and manual string concatenation.
## Motivation
The current implementation likely uses `strings.Builder` or similar manual string
construction, which can be harder to read, maintain, and modify. Using `text/template` would:
- Make the output format more declarative and easier to understand
- Separate the template structure from the data logic
- Make it easier to customize or extend the prompt format in the future
- Follow Go best practices for text generation
## Checklist
- [ ] Review the current `beans prompt` implementation to understand its structure
- [ ] Create a template file or embedded template string for the prompt output
- [ ] Refactor the command to use `text/template` with appropriate data structures
- [ ] Ensure the output remains identical to the current implementation
- [ ] Add/update tests to verify the refactored code produces correct output](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:r5vna26rxavzyk5iuyqumdrg/bafkreifvo6tfvjhnqzmc5thhyoi2cvv2jcazaemjfgto3umlyhr5cgwbvi@jpeg)

Migrated an entire Sendgrid account to a new account using Claude Code.
Gave it both API keys and told it to extract everything from A and recreate it in B. Templates, sender identities, the works.
No API docs, no migration scripts, no clicking through dashboards.
