安全使用建议
This skill appears to be a safe, read-only informational module about Discover Card. It asks for no credentials and performs no installs. If you plan to let agents act autonomously, be aware the agent platform (not this skill) might fetch live web data to verify or update facts; that network activity is outside the skill's provided instructions. If you need sourcing or live data, request the skill author add explicit, narrow instructions (e.g., which APIs to call) rather than enabling broad web searches.

Purpose & Capability
The skill's name/description match the SKILL.md content (historical, business, and factual notes about Discover). It does not request unrelated capabilities or credentials.
Instruction Scope
SKILL.md is purely informational (timeline, business model, facts). It does not instruct the agent to read system files, access environment variables, call external endpoints, or exfiltrate data.
Install Mechanism
No install specification or code files are present; this is instruction-only, which minimizes disk writes and execution risk.
Credentials
The skill declares no required environment variables, credentials, or config paths. Nothing asks for secrets or unrelated service keys.
Persistence & Privilege
always is false (default) and the skill does not request elevated or persistent privileges. Autonomous invocation is allowed by platform default but the skill itself has no operations that would abuse that.
