The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes several local git commands to manage the repository state.
git fetch --prune is used to update the local tracking info.
git branch -vv is parsed by a local script to identify branches marked as 'gone'.
git worktree remove and git branch -D are used to perform cleanups.
All destructive operations are explicitly gated by a user confirmation step to prevent unintended data loss.
[EXTERNAL_DOWNLOADS]: The skill performs a git fetch operation to synchronize with the remote repository. This is a standard and expected behavior for a branch management tool.
[INDIRECT_PROMPT_INJECTION]: The skill processes branch names originating from a remote repository, which represents a potential injection surface.
Ingestion points: Branch names are fetched from the remote and parsed in scripts/clean-gone.
Boundary markers: The skill presents the list to the user for confirmation but does not use specific delimiters or instructions to the agent to ignore embedded commands in branch names.
Capability inventory: The agent has the capability to delete files via git branch -D and git worktree remove.
Sanitization: The helper script validates that branch names are not empty and do not look like raw hashes, providing basic structural validation.
