Band: time left on the warm cache, hit rate, context as weather with its trend over 12 turns, plan limits, compact and keep-warm buttons; stops one send to a cold cache and names its cost (Cache Tax runs inside).

After every git push, follows the GitHub Actions runs (via gh) until they finish; with an open pull request (also after gh pr create, or /ci pr ) all its checks, other CI included, and whether it is ready to merge. On red it shows the failed step log.

/handoff writes a handoff note to .claude/handoff.local.md; a new session offers to continue from it.

Before Claude installs or runs a package (npm, pnpm, yarn, bun, npx, pip, uv, poetry, pipx, cargo), asks the public registry about it. Holds the command when the package does not exist (a made-up name), is under 14 days old, or looks like a well-known package and is young or thin (typosquatting). Allow in the band or with /pkg-allow.

A little companion on the Windows desktop, always on top: a cardboard box or one of twelve figures (cat, dog, fox, bunny, hamster, owl, penguin, frog, axolotl, dragon, robot, ghost; cat, dog and bunny in nine coats). It says in a speech bubble what Claude is doing, shows permission requests, and lets you click Claude's questions and Next Steps' suggestions right in the bubble. Drag it...

Holds a whole-file Read (no offset/limit) of a file above the limit, a lockfile, minified code or a source map, and the same via cat, type or Get-Content in the shell; tells Claude the size, a token estimate and a better way (Grep, offset/limit). A second try at the same file goes through, and so does a Read with allow_large. Claude Code itself stops only at about 25,000 tokens.

For screen sharing and recordings: hides API keys, tokens, private keys, e-mail addresses, IP addresses, your login name in paths and any names you list. Only the display changes; Claude still reads the original. Nothing leaves the machine. /mask switches it.

Stops before Claude writes API keys, tokens, private keys or a non-ignored .env into files, git add or commits. Exceptions for test keys and example files: /secret-allow.

Spots Windows builds (cargo --release, dotnet publish, go build, pyinstaller, tauri, electron-builder, msbuild) and signs the new .exe/.msi/.msix with your own signing script.

Search subagents (Explore) that were given no model of their own run on a cheaper one instead of the main model. An explicit model, forks, teammates and plugin agents stay untouched. With Claude Code's own CLAUDE_CODE_SUBAGENT_MODEL set (for all subagents), the mod stays out.
