Summary

This pull request (PR) adds a Python script that scans for unused images and deletes them. There are two just recipes that use the script:

  • just find-unused-images
  • just delete-unused-images

This is pre-work for restructuring the docs site. Fewer files means less validation work when moving things around.

In general though, it's a best practice in tech docs to prune unused assets on a periodic basis.

We can choose to keep unused images when we feel like it's necessary, but none of the images I'm seeing in this round look like they're worth keeping around.

Summary by CodeRabbit

  • New Features

    • Added scanning for unreferenced images in documentation assets and image directories.
    • Added detection of references between SVG assets.
    • Added optional deletion of unused images.
    • Added configurable paths, image locations, extensions, and searchable files.
  • Bug Fixes

    • Improved error reporting for unreadable files with an appropriate failure status.
  • Chores

    • Added convenient commands for finding and deleting unused documentation images.

Walkthrough

The PR updates the unused-image scanner to detect SVG references and stop on unreadable searchable files. It also adds justfile targets for scanning and deleting unreferenced documentation images.

Changes

Unused Image Cleanup

Layer / File(s) Summary
Image scanner and CLI
scripts/find_unused_images.py
The scanner supports SVG image files, propagates read errors, reports failures with status 2, and supports reporting or deleting unused images.
Justfile cleanup commands
justfile
The new targets run the scanner in report or deletion mode with strict Bash error handling. The OpenAPI comment now refers to the “BloodHound stage branch.”

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 2bee5

The new image-cleanup commands can miss some unused SVGs and may report success when scanning encounters errors, which could leave cleanup incomplete or hide failures from automation. The PR is otherwise mergeable with explicit owner awareness and follow-up on these bounded command-behavior issues.

failure instead of returning empty text, and ensure the scan exits with a
non-zero status when any searchable file raises OSError, preventing unused-image
classification or deletion from continuing.
- Line 27: Add “.svg” to the SEARCH_EXTS collection used by
iter_searchable_files so SVG references are scanned before unused-image
detection and deletion.

Exclude the candidate SVG from searchable files.

Because .svg is in SEARCH_EXTS, each candidate SVG is searched for its own filename. An otherwise unused SVG that contains its basename in metadata or embedded text is marked as referenced, so --delete does not remove it. Exclude image_path when checking references.
