List pending mempool transaction hashes via DERO.GetTxPool.
When to call: when checking unconfirmed activity, watching for a specific tx to land, or estimating mempool pressure. NOTE: tx_hashes may be null or an empty array when the mempool is empty — treat both as "no pending".
Input Requirements: none.
Output: { tx_hashes: string[] | null }.

Changes observed during successful MCP inspections.
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds valuable behavioral detail about possible null/empty tx_hashes, but doesn't disclose other traits like rate limits or pagination, which are not needed for this simple 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?
Extremely concise: three short paragraphs covering purpose, when to call, input/output. Every sentence adds value. Front-loaded with the core action.
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 zero parameters, existing annotations, and no output schema, the description fully covers the tool's behavior, output format, and edge cases. Nothing missing.
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?
No parameters exist, so baseline is 4. The description correctly notes 'Input Requirements: none' and schema coverage is 100% (vacuous). No further parameter info needed.
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 'List pending mempool transaction hashes' using a specific verb and resource, distinguishing it from sibling tools that deal with blocks, transactions, or other data.
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?
Provides explicit when-to-use scenarios: 'when checking unconfirmed activity, watching for a specific tx to land, or estimating mempool pressure.' Also explains how to handle null/empty response.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
