The Agent Skills Directory

[PERSISTENCE]: The skill records execution metadata by appending to a file at ~/.claude/projects/*/skill-telemetry.md. While intended for performance tracking, this creates a persistent side effect on the host filesystem by writing to a location outside the immediate project scope.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and analyze external codebases and user-provided arguments without explicit boundary markers or sanitization, creating a surface where malicious instructions embedded in analyzed code could influence agent behavior.
Ingestion points: Project codebase files and the $ARGUMENTS parameter.
Boundary markers: Absent; the skill lacks delimiters to distinguish between its own instructions and the content of the analyzed files.
Capability inventory: File system read (to audit code) and file system write (telemetry logging).
Sanitization: Absent; no escaping or validation is performed on the ingested content before processing.
