Changes observed during successful MCP inspections.
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations supplied, the description carries the full burden, and 'verify ... from genesis to head' does usefully disclose that this is a full-sweep operation rather than a spot check. However, it does not state whether the call is read-only, whether it can be expensive on long ledgers, or what happens when the chain is broken (error vs. a falsy result). Failure semantics are the significant gap for a verification tool with no output schema.
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?
A single front-loaded sentence with zero filler. The key scope constraint ('genesis to head') is placed where it will be read first, and nothing in the wording is redundant.
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 is simple (no inputs), but with no annotations and no output schema, the description leaves the caller unsure what a verification result looks like and whether a negative outcome surfaces as an error. For an integrity-verification tool, one clause about the result shape or failure behavior would close the remaining gap.
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 takes zero parameters, so there is nothing for the description to disambiguate beyond confirming the call is argument-free. Baseline 4 applies for a parameterless tool; the description correctly adds no spurious parameter talk.
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 combination: verifying the SHA-256 hash chain integrity of the ledger. It also scopes the operation to the full chain ('genesis to head'), so an agent knows exactly what is being checked. It does not explicitly contrast itself with the other trust/safety-adjacent siblings such as check_action_safety or query_graph, but the purpose is unmistakable.
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?
There is no guidance on when to invoke this versus alternatives, no stated prerequisites, and no warning about cost or duration despite the full-chain scope. An agent must infer that this is an audit/integrity check to run on demand rather than a routine read. No when-not-to-use conditions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
