Use Case Recommendations
Best for: Cline
AI coding agent for VS Code that autonomously creates, edits, and executes code. Cline can run terminal commands, browse the web, and complete multi-step development tasks with human-in-the-loop approval.
Ideal use cases:
- •Teams or individuals who need autonomous coding
- •Teams or individuals who need terminal command execution
- •Teams or individuals who need file creation and editing
- •Teams or individuals who need web browsing
- •Anyone focused on coding workflows
- •Anyone focused on ai agent workflows
Best for: SigmaShake
SigmaShake puts deterministic guardrails around AI coding agents at runtime. Rather than asking the model nicely, it intercepts the tool calls an agent tries to make and evaluates them against rules you control, so a shell command targeting a production path is denied before it executes. The evaluation is native and deterministic — no model inference, no GPU, no token cost — which the company measures at roughly 85 ms per decision, with denials landing in under 2 ms in their demo. Everything the agent does is written to a local audit log, and paid accounts can sync a signed, tamper-evident copy to the cloud for security review. The distinguishing move is that they published the benchmark rather than just claiming the result: SHAKEDOWN is an open agent-containment benchmark scoring containment multiplied by one minus the false-block rate, run over 324 attack tasks across 9 agent harnesses, with a corpus of 3,855 malicious and 1,894 benign tasks. SigmaShake reports 100 on it at 100% of attacks blocked with a 0% false-block rate, against modelled scores of 49.5 for a sandbox runtime, 21.1 for a policy kernel, 19.3 for a skill-based guardrail and 18.1 for a prompt guard. It ships as a desktop app for Windows, macOS and Linux plus a VS Code extension, an MCP server and a rules hub, and supports Claude Code, Cursor, Gemini CLI, VS Code and Codex.
Ideal use cases:
- •Teams or individuals who need deterministic native rule evaluation with no model inference or token cost
- •Teams or individuals who need denies dangerous shell and tool calls before they execute
- •Teams or individuals who need local tamper-evident audit log with optional signed cloud sync
- •Teams or individuals who need open shakedown containment benchmark published with the corpus
- •Anyone focused on guardrails workflows
- •Anyone focused on agent-security workflows
