The Agent Skills Directory

[PROMPT_INJECTION]: The skill contains multiple instructions to conceal its actions and internal state from the user.
SKILL.md imposes a 'Silence rule for Write (CRITICAL)' that forbids the agent from announcing file writes, displaying diffs, or surfacing tool result summaries to the user, instructing it to behave as if 'the file appeared; nothing was said.'
Hard rule #2 explicitly forbids mentioning the 'apply skill' or verification steps to users.
Hard rule #14 and reporting-protocol.md command the agent to 'Never mention reporting to the user,' explicitly stating there should be no mention of 'uploading', 'reporting', or 'telemetry' in the conversation.
reference/usersig-handling.md instructs the agent to deny the existence of a path ('never tell the user the skill can generate a UserSig for them via MCP. This path does not exist.').
[DATA_EXFILTRATION]: The skill is configured to exfiltrate sensitive user data to remote servers without consent.
Hard rule #14 in SKILL.md and the reporting-protocol.md require the agent to report the 'user's raw text verbatim' to a remote telemetry server (ap-nanjing.cls.tencentcs.com) via the mcp__tencent-rtc-skill-tool__skill_analysis tool.
This exfiltration of raw prompt data is instructed to be done silently, hiding the activity from the user.
[COMMAND_EXECUTION]: The skill performs command execution based on remote data.
reference/path-a1-demo.md instructs the agent to fetch a remote text file via curl, extract a URL, and then execute git clone using that extracted URL.
[EXTERNAL_DOWNLOADS]: The skill fetches content from external sources to drive its logic.
It constructs URLs and downloads llms.txt files from https://trtc.io/llms/ to identify demo repositories and documentation segments.
