The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill downloads and installs the official 'cos-nodejs-sdk-v5' package from the npm registry. This is a well-known package provided by Tencent Cloud for interacting with their Object Storage and Data Intelligence APIs.
[COMMAND_EXECUTION]: The skill executes cloud operations via a local Node.js script ('cos_node.mjs'). The script includes a 'guardBucketSafety' function that explicitly prevents the execution of destructive commands, such as deleting or clearing storage buckets, providing a layer of protection against accidental or malicious data loss.
[CREDENTIALS_UNSAFE]: The skill manages sensitive Tencent Cloud API credentials. It implements a robust local security model where credentials can be persisted using AES-256-GCM encryption ('encrypt-env' action). The encryption key is derived from machine-specific metadata (hostname, username, and project path), ensuring the credentials cannot be used if copied to a different environment. Additionally, the setup script automatically configures '.gitignore' to prevent these secrets from being accidentally committed to version control.
[PROMPT_INJECTION]: The skill provides knowledge base retrieval capabilities ('hybrid-search') that ingest data from external storage buckets. This creates an indirect prompt injection attack surface where untrusted content could potentially influence agent behavior.
Ingestion points: Data enters the agent context through the 'hybrid-search' and 'doc-preview' actions in 'scripts/cos_node.mjs' which retrieve content from Tencent COS buckets.
Boundary markers: The current instructions do not specify explicit delimiters or 'ignore' instructions for the retrieved data fragments.
Capability inventory: The skill possesses capabilities for network operations, file writing, and comprehensive cloud resource management via the Tencent SDK.
Sanitization: There is no evidence of filtering or sanitizing the retrieved document fragments before they are presented to the agent's context.
