Code Formatter: Format Code in Multiple Languages for Consistency and Readability

What Is Code Formatter?

Consistent code formatting is essential for team collaboration, code reviews, and long-term maintainability. However, every programming language has different conventions, and managing formatting across multiple languages can be overwhelming.

  • Keyword Casing: Normalize language keywords to standard casing conventions
  • Line Length Control: Break long lines intelligently based on configurable limits
  • Comment Preservation: Maintain your comments and documentation during formatting
  • Bracket Formatting: Properly align braces and parentheses for readability
  • Copy & Download: Copy formatted code or download as a file with original extension
  • No Configuration Required: Works with sensible defaults; customize when needed

Blocking rm -rf in Claude Code: A Deny Rule Stopped 14 Deletes in Two Weeks, 7 Other Spellings Still Get Through, and a Hook That Closes the Gap

To keep Claude Code from deleting things by accident, I added a deny rule, Bash(rm -rf *), to my global settings. Across my sessions from October 7 to 21 it blocked 14 deletes. After each denial the model picked a new directory name 8 times and dropped the delete 6 times. It never tried another spelling. Then I replayed 22 delete commands verbatim against Claude Code 2.1.285 through a stub. rm -fr, rm -r -f, rm -Rf and rm -r deleted the directory in manual, auto and bypass mode alike. /bin/rm, find -delete and bash -c deleted it in manual and bypass mode. In auto mode, rm -fr inside the working directory skips the classifier because it 'would be allowed in acceptEdits mode'. A second, built-in dangerous-rm check fires on targets like $D/*, even in bypass mode, but loses track of a variable assignment when a heredoc comes earlier in the same command. The post ends with a PreToolUse hook that blocks every recursive spelling in all three modes and tells the model what to do instead.

The Self-Reinforcing Flywheel Is Harder Than It Looks: 40 Days of an LLM Auto-Tuning Loop

We ran an 'LLM proposes, code decides' auto-tuning loop on a daily WeChat newsletter for 40 days: 18 versions, 8 rollbacks. Three of those rollbacks overturned decisions a human had made, and one version whose knobs were identical to its parent still got rolled back. Using our real numbers, telling apart a 20% difference needs about 25,000 reads per version. At 60 reads a day, that is more than 400 days. This postmortem covers five reasons the flywheel never turned, and what actually moved the numbers.
