Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, covering the safety profile. The description adds valuable behavioral context: verification is 'independent' (likely a direct chain query rather than cached data) and specifies the exact return contents, including an ABI summary of deposit/release/verify signatures.
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, information-dense sentence that front-loads the core action ('Independently verify the EscrowVault on-chain') and then lists concrete return fields. No filler or redundancy.
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 no-argument, read-only verification tool with a rich output schema, the description covers the essential behavioral and output details. The absence of explicit failure conditions or rate-limit notes is acceptable given the low complexity and strong annotation coverage.
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 baseline is 4. The input schema already states 'No arguments — the owner is derived from the authenticated principal,' which fully covers parameter semantics; the description has no need to add more.
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 verb and resource: 'verify the EscrowVault on-chain' and enumerates the exact outputs (address, chain id, RPC, explorer link, USDC token, ABI summary). This distinguishes it from generic contract tools and clearly communicates its scope.
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 implies when to use it: when an agent needs to independently verify the EscrowVault contract details on-chain. However, it does not explicitly contrast this with sibling tools like get_agent_contract or state when not to use it, leaving some inference to the agent.
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.
The data_session_* cluster has six closely related purchase-stage tools, and a2awire_guide/get_recommended_action/onboard_start all provide orientation guidance, creating some overlap. However, the descriptions are detailed enough to distinguish most tools, and the buyer vs. seller agent tools are fairly clear.
Most tools follow a readable snake_case verb_noun pattern such as check_earnings, discover_agents, and verify_contract, with a consistent data_session_* prefix. Exceptions like a2awire_guide and data_preview are noun-first, and hire_and_execute is a compound verb, so the pattern is not fully uniform.
Sixteen tools is borderline heavy, and the set includes a lot of A2AWire agent-marketplace plumbing that is not obviously needed for a server named after US economic releases. The data-session purchase flow is well represented, but many tools feel like platform infrastructure rather than focused economic-data functionality.
The per-query purchase flow is covered (preview, open, fund, attach escrow, query), but there is no obvious way to discover or list available CPI/Payrolls/Fed data listings. Session management is also thin, with no close, refund, or balance-inspection tool, and no direct economic-release-specific query surface.
