Using Architecture Compiler

Security checks for vulnerabilities and agentic risk

Overview

This is a small routing skill for architecture workflows, with no bundled executable code or hidden data access.

Before installing, confirm you trust the Architecture Compiler repo and understand that this package expects companion local files and skills to be present; the reviewed file itself is only routing guidance.

A.I.G

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

Skill Enumeration

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

## Routing Rule

Use `skills/compiling-architecture/SKILL.md` when:
- the user wants to turn requirements into architecture decisions
- the user wants to write or refine a spec
- the user wants to compile, recompile, inspect pattern selection, or finalise an architecture

- any later decision would change `constraints.*`, `constraints.saas-providers`, top-level `patterns.*`, or accepted risk posture
- the user wants existing prototype choices to replace approved providers, boundaries, or selected patterns

Use `skills/implementing-architecture/SKILL.md` when:
- `docs/architecture/architecture.yaml` exists
- it is approved
- the task is to write code that follows that architecture
