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

With no annotations supplied, the description carries the full burden, and it does disclose key traits: 'Public read' scope and 'Side effects: None (read-only)'. However, it says nothing about permission requirements beyond 'PUBLIC', rate limits, or the shape/size of the returned JSON, so behavioral disclosure is partial but meaningful.

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?

Two compact sentences plus a bracketed visibility tag, all front-loaded with the resource scope before the return/side-effect notes. Nothing is redundant or padded.

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 zero-parameter, read-only introspection tool this is nearly complete: it states what is inspected, that the result is system JSON, and that there are no side effects. The only minor gap is the absence of output schema, only lightly compensated by 'Returns system JSON configuration'.

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?

The tool takes zero parameters, which is the baseline case for a 4. The description correctly implies a parameterless global inspection with no scoping options, and nothing in the text contradicts that.

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 uses a specific verb ('Inspect') with clearly enumerated resources: system baseline policies (HMC, Budget, 6-Step), agent identity, and capability whitelist. This distinguishes it well from siblings like session_status or safety_guard, though it does not explicitly contrast itself with any of them.

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?

Usage is only implied: an agent infers it should call this when it needs to discover system configuration or its own identity/whitelist. There is no explicit when-to-use versus when-not, and no sibling alternative is named for overlapping needs (e.g., session_status).

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