## TL;DR

```text
[WinError 206] The filename or extension is too long
```

## Steps

1. A fix was merged and shipped in the release after the report, shortening how
the git command is constructed. The reporter tested the fix branch and confirmed
it resolves the crash. Upgrade ggshield to a release newer than the report:

```
pip install --upgrade ggshield
```

2. WinError 206 on a pre-commit hook, when the same hook works on smaller commits,
is almost always a command-line length problem, not a file problem. Tools that
pass file lists as argv hit it; the fix is on the tool side.

## When to use

You are seeing this: On Windows, ggshield secret scan pre-commit crashes with: `` [WinError 206] The filename or extension is too long `` when committing a merge with many files and long file names. ggshield builds a git command line that exceeds Windows path limits. Use this skill when you run into "ggshield pre-commit crashes with WinError 206 on large Windows merges".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
