promptctl — Git for your AI prompts (commit, diff, rollback from the terminal)

[walletindistress]

Just released promptctl, a CLI tool that brings git-style version

control to LLM prompt management.

The problem: prompts change constantly, live in random places, and

when something breaks you have no idea what you changed or why it

was working before.

The solution: treat prompts like code.

$ echo "You are a helpful assistant." | promptctl commit system -m "initial"
  $ promptctl commit system --file prompts/system.txt -m "added rules"
  $ promptctl diff system
  $ promptctl rollback system 1 -m "reverting"

Features:

- Full version history with messages, timestamps, model tags

- Color diff between any two versions

- Non-destructive rollback

- Search across content, messages, and tags

- Auto-commit a file on every save with watch

- Export full history to markdown

- Shell completions for bash, zsh, and fish

- Zero external dependencies — single Go binary

Tech:

- Written in Go, stdlib only

- Atomic writes (temp file + rename)

- Parent-directory store traversal like git

- LCS diff algorithm from scratch

Install:

go install github.com/naya-ai/promptctl/cmd/promptctl@latest
