The Agent Skills Directory

[DATA_EXFILTRATION]: The skill explicitly reads ~/.claude/history.jsonl, a sensitive local file containing the user's entire interaction history with the AI agent. This file often contains proprietary code, business logic, and sensitive project information.
[DATA_EXFILTRATION]: Content derived from the chat history is transmitted to an external Slack workspace using the RUBE_MULTI_EXECUTE_TOOL. This creates a network exfiltration path for data originally stored in a private, local log file.
[CREDENTIALS_UNSAFE]: Local chat history files commonly contain API keys, session tokens, or environment variables that users may have pasted during debugging or development. The skill's process of reading and summarizing this file risks exposing these credentials in the final Slack report.
[INDIRECT_PROMPT_INJECTION]: The skill ingests data from two untrusted sources: the local chat history (which could contain malicious instructions from previous sessions) and HackerNews search results.
Ingestion points: ~/.claude/history.jsonl (Instruction 1) and HackerNews via RUBE_SEARCH_TOOLS (Instruction 5).
Boundary markers: The skill lacks explicit boundary markers or instructions to ignore embedded commands within the ingested text.
Capability inventory: The skill possesses the capability to send formatted messages to external Slack DMs via RUBE_MULTI_EXECUTE_TOOL.
Sanitization: No sanitization, filtering, or escaping logic is present to prevent sensitive data or malicious instructions from being processed and forwarded.
