Preliminary Cost Estimate Report
Security checks for vulnerabilities and agentic risk
Overview
This skill is a markdown-only guide for producing draft preliminary construction cost estimates and does not request unsafe system access or hidden actions.
This appears suitable to install if you need help drafting preliminary cost estimate reports. Treat outputs as planning drafts only: verify rates, indices, escalation, and assumptions with a qualified QS or cost manager before using them for budgeting or owner presentation.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
