The Agent Skills Directory

[PROMPT_INJECTION]: The skill possesses an indirect prompt injection attack surface because it ingests untrusted external data from multiple sources to perform its analysis.
Ingestion points: The skill reads transactions.json, tb_adjusted.json, and various Markdown files within the workpapers/ directory (SKILL.md).
Boundary markers: The instructions do not define delimiters or specific boundary markers to separate data from instructions during processing.
Capability inventory: The skill has the capability to write to the file system, specifically updating engagement_state.json and creating workpapers/qc_report.md (SKILL.md).
Sanitization: There is no evidence of data sanitization, escaping, or validation of the contents of the processed financial files before they are interpreted by the agent.
[DATA_EXFILTRATION]: The skill accesses highly sensitive financial information, including trial balances, transaction logs, and engagement state files. While the skill documentation states there is no external send, the access to these files is a necessary data exposure for the accounting QC process.
[COMMAND_EXECUTION]: The skill performs file system write operations to record QC results. No patterns of arbitrary shell command execution or unauthorized system modifications were detected.
