New Claude Code Tool Reveals Hidden Power To Delete Your Digital Clutter
By 813 Staff
What does it actually mean for an AI coding assistant to clean up after itself? That’s the question rippling through developer circles this morning after Boris Cherny (@bcherny) posted a cryptic look at a new feature shipping inside Claude Code. The tweet, dated July 8, 2026, reveals a command called `/checkup` designed to, in Cherny’s words, “clean up unused” resources. Engineers close to the project say the feature is more than a trivial housekeeping tool—internal documents show it’s built to scan for deprecated dependencies, orphaned configuration files, and stale code paths that accumulate during long sessions of AI-assisted development.
The timing is noteworthy. Claude Code has been rolling out aggressively to enterprise teams since late 2025, and the rollout has been anything but smooth. Early adopters reported bloated project directories and phantom imports left behind after iterative refactoring cycles. One senior engineer at a mid-size SaaS firm, who spoke on condition of anonymity, described spending nearly as much time undoing Claude’s mess as they saved using it. `/checkup` appears to be Anthropic’s direct response to that feedback—a self-repair mechanism baked into the agent itself.
According to sources who have tested the feature in private preview, `/checkup` runs a targeted audit of the current workspace, flagging files that aren’t referenced anywhere in the active dependency graph. It then presents a diff-like summary for the user to review before deletion. Unlike broader linters or `npm prune` equivalents, it’s context-aware: it understands which parts of the codebase were generated or modified by Claude during the current session versus pre-existing project code. That distinction matters. The last thing anyone wants is an AI accidentally trashing a legacy module it didn’t write.
What’s less clear is how `/checkup` handles edge cases like dynamically imported modules or files referenced through string concatenation. Anthropic has not published a formal changelog for this feature, and company spokespeople declined to comment on a timeline for general availability. However, given that Cherny—a well-known TypeScript advocate and former engineering lead—is publicly teasing it, I’d expect a wider release within weeks. For now, developers using Claude Code should watch for the command in upcoming nightly builds. If it works as promised, it could finally answer the industry’s lingering question about whether AI coding tools can be trusted to clean up their own workspace.
