5 automation recipes with Claude Code

Claude Code is a CLI tool that can read, write, run commands, search files and call other APIs. In the hands of someone who understands this, it becomes an automator for almost any routine.

Five real scenarios.

1. Automatic changelog from git

Task: every Friday, write a report on what the team did this week.

Solution: Claude Code reads git log for the last 7 days, groups by author, classifies PRs by category (feat/fix/chore), writes human-readable copy.

claude "Read git log for the past week, group by authors and change types,
write a short changelog in markdown format"

Saves 40 minutes every Friday.

2. Context-aware bulk refactor

Task: rename getUser to fetchUser across the entire repo — but only where it refers to an HTTP request, not an internal getter.

Solution: Claude Code greps all occurrences, analyzes the context of each, applies targeted replacements.

Plain grep-replace can't do this — it needs contextual analysis.

3. Auto-writing tests for untested code

Task: 40 utilities in the project have no tests. Cover at least the main ones.

Solution:

claude "Go through all files in src/utils/, for every one without a corresponding
.test.ts file, write unit tests with reasonable coverage"

In an hour, Claude writes dozens of tests. They need review, but the foundation is there.

4. Parsing logs and creating tickets

Task: read production server logs once a day, identify recurring errors, create tickets in Jira/Linear.

Solution: a cron job that runs Claude Code with access to logs and the Jira API.

Fully autonomous, with a human only in a reviewer role.

5. Automatic documentation updates

Task: the project README is stale, code comments don't match reality.

Solution:

claude "Walk through the public APIs in src/, check whether their real signatures
match the README. Update the README where they diverge."

Once a month — and the docs are always current.

The big picture

Claude Code isn't a replacement for a developer. It's a developer working for you in the background while you're busy with something else. Set it up properly and you get a +1 mid-level engineer on your team for $20 a month.
