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

The read-only, idempotent, non-destructive profile is covered by annotations, and the description adds content expectations such as MUST/MUST_NOT rules, legacy session/workday treatment, and probe guidance. However, the phrase 'Share with other agent runtimes' is ambiguous about whether this is an agent directive or a tool side effect, which slightly muddy the behavioral picture.

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 short and front-loaded with the protocol name and purpose, but it packs in cryptic phrases like 'Pilot Challenge Exact $100 wealth path' and 'LEGACY Session/Workday OFF TABLE as primary' that are hard to parse and may confuse agents. The 'Share with other agent runtimes' sentence adds little tool-selection value.

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?

Given no parameters, rich safety annotations, and a provided output schema, the description is adequate for a low-complexity read-only protocol tool. However, with 23 sibling tools, clearer guidance on when to fetch this protocol versus using other sqlguard tools would make the definition more complete.

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?

There are zero parameters and the schema is complete, so no parameter documentation is needed. The description does not need to compensate for schema gaps because none exist.

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 states a concrete deliverable ('Returns MUST/MUST_NOT rules') and identifies the resource as the ABMP normative protocol with SQLGuard as reference implementation. It conveys an information-retrieval tool rather than a mutating one, though some listed contents are cryptic and sibling boundaries are not explicitly drawn.

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?

No explicit when-to-use guidance or alternatives are provided. 'Share with other agent runtimes' is an instruction about handling output, not a criterion for choosing this tool over siblings like sqlguard_probe, sqlguard_gate, or sqlguard_require.

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