The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses standard git commands such as git log, git diff, and git show to retrieve information about recent code changes. These operations are conducted locally and are essential for the skill's stated purpose of backfilling documentation.
[COMMAND_EXECUTION]: It performs file writing operations to create documentation files in the docs/plans/ and ~/.claude/plans/ directories, followed by git add and git commit to persist these changes. These are expected behaviors for a documentation automation tool.
[PROMPT_INJECTION]: The skill exhibits an attack surface for indirect prompt injection as it processes untrusted data from git commit messages and source code comments. If these sources contain malicious instructions, the agent might inadvertently follow them while generating summaries. However, this is a known limitation of LLM-based summarization tasks and does not indicate malicious intent within the skill itself.
[DATA_EXPOSURE]: The skill reads project source code and history. While this involves accessing potentially sensitive logic, the data remains within the local environment and is used solely for the intended purpose of documentation.
