• The repository root detection logic requires the command to be run from within the qsv repository directory tree. This creates a usability issue: users who install qsv via package managers (brew, cargo install, etc.) will have the binary installed in a different location and won't have the repository checked out. The documentation suggests users can simply run qsv --update-mcp-skills from anywhere, but this will fail unless they're in the repository directory.

Consider either:

1. Adding an environment variable or CLI argument to specify the repository path (e.g., --repo-path /path/to/qsv)
2. Using the binary's own location to determine a default skills output directory (e.g., in user config directory)
3. Clearly documenting in AUTO_UPDATE.md that this command must be run from within the qsv repository directory

This affects the auto-regeneration feature as well, since it spawns qsv --update-mcp-skills which would fail if the current working directory isn't within the repository.

• The error message on line 618 calls std::env::current_dir()? again, which could potentially fail differently than the original call on line 603 if the directory was deleted or permissions changed during execution. This would result in a propagated error instead of the intended error message.

Consider storing the original current directory path before the loop and using that in the error message, or handle the potential error from the second current_dir() call explicitly.
src/mcp_skills_gen.rs:621

• The repository root detection logic has a potential issue with symlinks. If the current directory contains symlinks in its path, repo_root.pop() might fail to navigate correctly through the directory tree, or it might exit the repository without finding Cargo.toml.

Additionally, on some filesystems or configurations, repeatedly calling pop() until it returns false could reach the root directory ("/") and continue checking, which is inefficient. Consider adding a maximum iteration count or checking for the filesystem root explicitly.
src/mcp_skills_gen.rs:599

• The commands vector is hardcoded and manually maintained. If new commands are added to qsv or existing commands are renamed/removed, this list needs to be manually updated. This creates a maintenance burden and risk of the list becoming stale.

Consider either:

1. Dynamically discovering command files by reading the src/cmd directory
2. Adding a comment with instructions for how to regenerate this list
3. Adding a test that verifies all .rs files in src/cmd (except mod.rs) are included in this list

This would make the code more maintainable and less error-prone as the project evolves.

src/mcp_skills_gen.rs:614

• The loop logic has a subtle bug: the iteration counter is incremented before checking if the repository root was found, which means the loop can execute MAX_ITERATIONS + 1 times instead of MAX_ITERATIONS times.

The iteration count should be incremented after the check on line 610-612, not before attempting to pop the path. This ensures the loop executes exactly MAX_ITERATIONS times before failing.
src/mcp_skills_gen.rs:643

• The repository root detection logic has a potential issue: after incrementing iterations and checking MAX_ITERATIONS (line 614-629), the code then checks if pop() fails (line 631-643). However, the error message at line 631-643 will never be reached because if we've hit MAX_ITERATIONS, we've already returned an error on line 616.

The condition at line 631 should be checked before incrementing and checking MAX_ITERATIONS to provide a more accurate error message when the filesystem root is reached without finding the repository.
