__unlock_blockchain_analysis__

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

The description adds significant behavioral context beyond annotations: it explains that all tools remain locked until this is called, that it returns essential rules for blockchain interactions, and that it provides a catalog of data sources. While annotations indicate read-only and non-destructive behavior, the description enriches understanding of the initialization mechanism and post-call requirements.

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 well-structured with clear sections: purpose, mandatory nature, and data sources. Each sentence adds value, though it could be slightly more concise by combining some of the imperative warnings. The information is front-loaded with the core purpose in the first sentence.

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 zero-parameter initialization tool with annotations covering safety (readOnlyHint, destructiveHint), the description is complete: it explains the prerequisite role, consequences of skipping it, what it returns (rules and data source catalog), and how it enables other tools. No output schema exists, but the description adequately covers expected outcomes.

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 0 parameters and 100% schema coverage, the baseline would be 4. The description adds value by explaining why there are no parameters (it's a simple unlock/initialization function) and what happens when called, which goes beyond the empty schema.

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 purpose as 'Unlocks access to other MCP tools' and explains it initializes the session to prevent 'Session Not Initialized' errors. It distinguishes itself from all sibling tools by being the mandatory initialization step rather than a data retrieval or analysis function.

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 provides explicit usage guidance: 'MANDATORY FOR AI AGENTS' indicates this must be called first, 'Skipping this explicit initialization step will cause all subsequent tool calls to fail' explains the consequence of not using it, and it implicitly positions this as a prerequisite to all other blockchain tools in the sibling list.

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