Skill202 starsChanged 14 days agoMITView on GitHub

Normalizes asset filenames by splitting on common separators, stripping asset IDs and optional user strings from each segment, then joining with underscores (snake_case). Use when normalizing asset filenames, batch-renaming SFX/UI textures, file naming normalization, asset naming convention, slug normalization, or snake_case asset names.

The file

We split this skill into the rules it gives an agent

9 rules. About 0 are common, 2 are distinctive, and 7 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 7

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    When this skill applies, read and follow dependency-manager — run scripts as documented, install missing tools into .dependency/.

    line 12
  2. Very specific:

    Default: split on _, -, ., and spaces.

    line 16
  3. Very specific:

    Keep short pure-digit segments as variant indices (1, 2, 01)

    line 33
  4. Very specific:

    Remove leading digits from mixed segments (001Hero → Hero)

    line 34
  5. Very specific:

    Remove trailing digits from mixed segments (Attack02 → Attack, foisal72 → foisal)

    line 35
  6. Very specific:

    Remove user-given strings (see --strip)

    line 36
  7. Distinctive:

    Use the bundled script; do not hand-write rename loops unless the script cannot cover the case.

    line 118
  8. Very specific:

    Always run --dry-run first when normalizing many files.

    line 119
  9. Distinctive:

    Only renames files; does not rename directories.

    line 123

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

File Naming Normalization

Normalize asset filenames: split → clean each segment → join with _ (snake_case).

Rules

When this skill applies, read and follow dependency-manager — run scripts as documented, install missing tools into .dependency/.

Quick Start

Default: split on _, -, ., and spaces; strip leading/trailing digits from each segment; join with _:

.dependency/python/python .ai/file-naming-normalization/normalize.py path/to/file_or_folder

Preview without renaming:

.dependency/python/python .ai/file-naming-normalization/normalize.py Audio/SFX --dry-run

Workflow

  1. Split the filename stem (extension is preserved) on common separators: _, -, ., whitespace.
  2. Clean each segment:
    • Drop pure-digit segments with 4+ digits (asset IDs like 38126)
    • Keep short pure-digit segments as variant indices (1, 2, 01)
    • Remove leading digits from mixed segments (001Hero → Hero)
    • Remove trailing digits from mixed segments (Attack02 → Attack, foisal72 → foisal)
    • Remove user-given strings (see --strip)
  3. Drop empty segments after cleaning.
  4. Join remaining segments with _.
  5. Rename in place (or write to --output-dir).

Examples

InputOutput
001_Hero_Attack_02.wav001_Hero_Attack_02.wav (already snake_case)
001-Hero-Attack-02.wav001_Hero_Attack_02.wav
sfx-button-click.mp3sfx_button_click.mp3
UI 12 Panel Open.pngUI_12_Panel_Open.png
freesound_community-shoot-1-81135.wavfreesound_community_shoot_1.wav
SFX_001_button.wav with --strip SFX001_button.wav
# Strip custom strings (repeatable)
.dependency/python/python .ai/file-naming-normalization/normalize.py Assets --strip SFX --strip UI

# Recursive folder
.dependency/python/python .ai/file-naming-normalization/normalize.py Assets -r

# Copy normalized files to another folder (originals unchanged)
.dependency/python/python .ai/file-naming-normalization/normalize.py Assets -o normalized/ -r

Output

--dry-run preview (unchanged files such as 001_Hero_Attack_02.wav are omitted):

Assets/001-Hero-Attack-02.wav -> Assets/001_Hero_Attack_02.wav
Assets/freesound_community-shoot-1-81135.wav -> Assets/freesound_community_shoot_1.wav
Assets/sfx-button-click.mp3 -> Assets/sfx_button_click.mp3
Assets/UI 12 Panel Open.png -> Assets/UI_12_Panel_Open.png

Dry run: 4 file(s) would be renamed.

In-place rename:

Assets/001-Hero-Attack-02.wav -> Assets/001_Hero_Attack_02.wav

Renamed 1 file(s).

Nothing to change:

All filenames already normalized.

With --strip SFX:

Assets/SFX_001_button.wav -> Assets/001_button.wav

Renamed 1 file(s).

Copy to --output-dir (originals kept):

Assets/SFX_001_button.wav -> normalized/001_button.wav

Renamed 1 file(s).

Name collision (exit code 1):

Name collision: 'Assets/Hero-Attack.wav' and 'Assets/Hero.Attack.wav' both map to 'Assets/Hero_Attack.wav'

Common Flags

-r / --recursive · --strip TEXT (repeatable) · --strip-case-insensitive · -o / --output-dir · --dry-run · --overwrite

Agent Notes

  1. Use the bundled script; do not hand-write rename loops unless the script cannot cover the case.
  2. Always run --dry-run first when normalizing many files; show the user the preview.
  3. --strip removes the given substring anywhere inside each segment (not only at edges). Pass one --strip per string.
  4. Segments that become empty after cleaning are dropped (81135 alone → skipped).
  5. Collisions (two files mapping to the same name) abort with an error — resolve manually or normalize in smaller batches.
  6. Only renames files; does not rename directories.
