The Agent Skills Directory

[PROMPT_INJECTION]: Indirect Prompt Injection Surface. The skill is designed to ingest and process untrusted external data, such as emails, PDFs, and legal documents, which may contain malicious instructions designed to hijack the agent's logic during extraction.
Ingestion points: Processes user-provided files, case folders, and declared sources (Step 1 and 2 in SKILL.md).
Boundary markers: The skill does not specify the use of delimiters or instructions to ignore embedded commands within the ingested content.
Capability inventory: The agent performs file read operations on various document types and write operations to the local filesystem (Step 8).
Sanitization: There is no evidence of sanitization or safety-filtering for the content extracted from external documents.
[COMMAND_EXECUTION]: Filesystem Operations and Path Construction. The skill reads from and writes to the ~/.claude/plugins/config/claude-for-legal/ directory. While this is expected for a legal plugin, the use of the user-supplied [slug] variable to construct file paths (e.g., matters/[slug]/matter.md) could lead to path traversal if the agent does not restrict the input to alphanumeric characters, potentially allowing access to files outside the intended subdirectory.
