The Agent Skills Directory

[PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection by design, as it parses untrusted conversation history to generate instructions for future agent tasks.
Ingestion points: Analyzes the current conversation history (Step 1) to extract steps and patterns.
Boundary markers: The skill does not define strict boundary markers or sanitization logic to prevent malicious instructions embedded in the conversation from being included in the generated playbook.
Capability inventory: The skill uses Bash and Write to create and store the resulting playbooks.
Sanitization: There is no explicit sanitization of the extracted content beyond filtering for the 'successful path'.
[COMMAND_EXECUTION]: The skill uses the Bash tool to perform filesystem operations.
Evidence: Step 10 executes mkdir -p and cat to create and verify the new playbook files in .claude/skills/ or ~/.claude/skills/.
[DATA_EXPOSURE]: The skill processes the entire conversation history, which may contain sensitive data disclosed during the workflow.
Evidence: Step 1 explicitly reviews goals, read/written files, and API calls from the history to construct the playbook.
