The Agent Skills Directory

Command Execution: The skill includes a Python script (scripts/review_state.py) and associated tests that utilize subprocess.check_output to execute Git commands. These operations are used to retrieve repository status, diffs, and file metadata to generate cryptographic fingerprints. The commands are constructed using list-based arguments, which prevents shell injection, and input validation is performed on user-supplied pathspecs to ensure they are well-formed.
Data Integrity and Fingerprinting: The system generates SHA-256 fingerprints of the repository's content (including files, symlinks, and gitlinks). This is a security-positive feature designed to 'freeze' the task-owned content during review, ensuring that reviewers are inspecting the exact state of the code and that any subsequent changes invalidate the review credit.
Secure Auditing Workflow: The instructions in SKILL.md define a 'risk-tiered' review process that mandates independent review for elevated-risk changes (e.g., security, persistence, or concurrency modifications). It includes detailed inventories for contract surfaces and data flows, encouraging a deep security-focused analysis of code changes.
Trusted Origin: The skill is authored by a trusted vendor, and all included scripts and instructions are consistent with professional development and auditing tools. The internal tests (test_review_state.py and test_skill_contract.py) further verify the consistency and correctness of the fingerprinting logic and the instruction set.
