Checkly Cli Skills

· v1.0.1

Medium Risk

Comprehensive Checkly CLI command reference and Monitoring as Code workflows. Use when user mentions Checkly CLI, monitoring as code, synthetic monitoring, API checks, browser checks, Playwright testing, check deployment, or npx checkly commands. Routes to specialized sub-skills for auth, config, checks, testing, deployment, imports, constructs, and advanced patterns. Triggers on checkly, monitoring as code, synthetic monitoring, checkly cli, npx checkly.

🔒 Containment

Level: maximum

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Unauthorized tool use: INSTRUCTED_BINARY_INSTALL, MCP_SYS_CRITICAL_ACCESS high

Mitigation: Avoid instructing agents to install arbitrary binaries; bundle dependencies or use sandboxed environments

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Tool poisoning: hidden behaviors detected (MCP_TOOL_POISONING_SENSITIVE_DATA) high

Mitigation: Remove references to sensitive data collection.

Data exfiltration patterns: MCP_EXFIL_EXTERNAL_UPLOAD high

Mitigation: Document all external data transfers. Remove suspicious upload references.
