Model Safety MCP

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'heuristic inspection' which implies analysis rather than modification, but doesn't specify whether this is read-only, what permissions are needed, what happens during inspection, or what the output format might be. The description is too vague about the actual behavior beyond the high-level purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that gets straight to the point without unnecessary words. It's appropriately sized for the complexity level, though it could benefit from being more informative while maintaining brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 2 parameters, no annotations, no output schema, and 0% schema description coverage, the description is inadequate. It doesn't explain what the tool actually returns, how to interpret results, or provide any context about the inspection process beyond the high-level purpose.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage and 2 parameters (path, url), the description provides no information about what these parameters mean, their relationship, or usage. The description doesn't mention parameters at all, leaving the agent to guess whether to provide a path, URL, or both for the inspection.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Run heuristic inspection') and target ('risky file types and embedded pickle members'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'modelscan_scan' or 'picklescan_scan', which appear related to scanning/inspection tasks.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus the sibling tools (artifact_safety_report, modelscan_scan, picklescan_scan, scan_directory_tool). There's no mention of prerequisites, alternatives, or specific contexts where this inspection method is preferred over others.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
