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

Annotations already mark readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds useful behavioral context: real-time synthesis from live sources, a signed receipt proving which sources were consulted, and a $1.00 USDC cost. It does not disclose rate limits or latency, but the provenance and pricing details go beyond what annotations provide.

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 sentences, front-loaded with the core purpose and agency coverage, followed by output specifics and cost. There is no filler; each clause adds functional information.

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 output schema, the description does at least say what is returned: synthesized developments and a signed receipt. It omits return format, error conditions, pagination, and parameter interplay, and with so many sibling get_* tools, some routing guidance would help. It is adequate but not comprehensive.

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 schema description coverage at 0%, the description carries the full burden. It identifies 'topic or agency' and lists SEC, FTC, OCC, CFPB, FDA as agency options, giving some semantic anchoring. However, it never clarifies whether agency is optional, whether both topic and agency can be combined, accepted formats, or the relationship between the two, leaving an agent uncertain on invocation.

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 names a specific action (real-time synthesis) and resource (regulatory news for a topic or agency), and it lists the covered agencies (SEC, FTC, OCC, CFPB, FDA). It also states the output: enforcement and rule-change developments with a signed receipt. It does not explicitly distinguish itself from similar siblings like get_ftc_enforcement_history or get_legislative_intelligence_synthesis, so it falls just short of a 5.

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 real-time/current/live sources language implies the tool is for up-to-the-minute synthesis rather than historical record lookup. However, the description never says when not to use it, nor does it name alternatives such as get_sec_beneficial_ownership or get_ftc_enforcement_history. Usage must be inferred, not prescribed.

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