Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds product scope ('active products', 'Hermes Plant catalog') but does not disclose any additional behavioral traits like pagination, ordering, or filtering. This is consistent with annotations and acceptable for a simple list tool.
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 sentence that immediately states the action and object. It is concise, front-loaded, and contains no filler.
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?
The tool has no parameters, has an output schema, and annotations cover safety. The description is sufficient for an agent to understand when to invoke the tool and what to expect at a high level.
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 has zero parameters, so the schema provides full coverage. The baseline for 0 params is 4, and the description does not need to compensate for any missing parameter information.
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 tool's function: 'List active products' from a specific catalog. The verb 'List' and resource 'active products from the Hermes Plant catalog' are specific, and the plural 'products' distinguishes it from the sibling 'get_product'.
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 context is clear: use this tool to retrieve a list of active products. It does not explicitly mention alternatives like 'get_product' for single-product retrieval, but the naming and description make the use case obvious.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes. Some overlap exists (e.g., dealanalyzer_analyze combines CashflowLens and WaterfallLens; action_safety_run includes DestructGuard evidence), but descriptions explicitly clarify scope so an agent can choose correctly.
Naming patterns are mixed: some verbs precede nouns (get_product, purchase_with_x402), others follow nouns (bond_analyze, portfolioguard_score), and some are multi-word (action_safety_quick_gate). This inconsistency makes tool selection less predictable.
At 25 tools, the server is at the heavy end and spans diverse subdomains (safety, payments, financial analytics, storefront). While each tool serves a purpose, the broad scope makes it feel overloaded for a single server.
Core assurance workflows (safety, payment, verification) are covered, but gaps exist: no refund/cancellation tools, no attestation lookup, and no way to retrieve 30-day action-safety status records. Financial analytics also have limited coverage (no equities).
