Are you tired of AI coding agents (Claude, Cursor, Devin) ignoring your instructions, deleting the wrong files, or pushing code without tests?

Prompts are not enough. Prompt injection defence is impossible. To truly control an agent, constraints must be enforced at the OS and code level.

• Agent decides to skip writing tests because it's "too trivial".
• Agent runs rm -rf by mistake during a multi-step refactor.
• Agent outputs a feature without ever writing a design doc.
• Agent ignores your 5,000-word system prompt because its context window is full.

• MCP SecurityGuard intercepts and blocks dangerous commands at the OS level.
• MCP Reviewer forces the agent into a strict retry-loop if output doesn't match the template.yaml.
• Pre-commit Hooks ensure the agent hasn't tampered with the rules themselves.
• Inversion Pattern forces the agent to stop and ask you clarifying questions instead of hallucinating.
