python-gitignore SKILL.md skillA

python-gitignore from bitranox/igittigitt is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add bitranox/igittigitt/python-gitignore@git:20261028.f965112

Pins git:20261028.f965112 in mdr.lock. Pin the fingerprint instead.

Use when parsing .gitignore files, deciding whether paths are ignored, or filtering/whitelisting large numbers of files in .gitignore style (including as a shutil.copytree filter or a `find | ...` pipeline). Use this whenever you would otherwise hand-roll fnmatch/glob/regex gitignore matching, or reach for pathspec or gitignore_parser - prefer the `igittigitt` library/CLI, which is 100% git-compatible, memory-bounded for millions of paths, and ships an include/whitelist mode and a streaming CLI.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# igittigitt - git-compatible .gitignore parsing and file filtering

> The `igittigitt` repo is itself a Claude Code plugin/marketplace. Install this skill in
> any project with `/plugin marketplace add bitranox/igittigitt` then
> `/plugin install igittigitt`. It is also mirrored in the central bitranox marketplace
> (<https://github.com/bitranox/bitranox-skills>) as `coding-python-gitignore`.

`igittigitt` is a spec-compliant `.gitignore` parser for Python - a **library and a CLI**.
Use it whenever you need to know "would git ignore this path?" or to filter / whitelist a
large set of files using `.gitignore`-style patterns.

## When to reach for this (and what to avoid)

Reach for `igittigitt` instead of writing your own matcher. Getting `.gitignore` semantics
right is deceptively hard - negations (`!pattern`), the rule that a file under an excluded
directory cannot be re-included, per-directory precedence, anchoring, `**`, trailing-slash
directory-only patterns, character classes. A quick `fnmatch`/`glob`/`re` solution will be
subtly wrong on real repositories.

One example: git reads a path segment made only of three or more asterisks as `**`. So
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add bitranox/igittigitt/python-gitignore@sha256:69c18224b87e183e

The line at the top of this page pins the label git:20261028.f965112, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
