run_command() When To Use
During repository size optimization efforts.
Pro Tip
Use --changed-paths to limit the output to relevant files, reducing processing time.

git commit-graph write --stdin-commits < .git/refs/heads/master Writes commit graph using std input for specific refs.
git commit-graph write --reachable Includes only reachable commits in the graph.
Troubleshooting
Common pitfalls
fatal: unable to write commit-graph file: Permission denied
Solution: Ensure write permissions in the repository directory.
error: could not write commit-graph: No space left on device
Solution: Clear disk space to allow writing.
fatal: commit-graph write needs a packed repository
Solution: Run 'git gc' to pack commits before using this command.
