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

With no annotations, the description carries full burden but only states it 'checks' components. It does not disclose whether the tool modifies state, requires specific permissions, or how it handles failures. For a test tool, this behavioral opacity is a significant gap.

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 consists of two concise sentences that immediately state the tool's purpose and scope. Every word adds value, and there is no extraneous information.

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 the lack of output schema, annotations, and parameters, the description should provide more context about test results, error handling, or prerequisites. As a diagnostic tool, it is incomplete without clarifying what 'end to end' means or how to interpret 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?

The input schema has no parameters, so schema coverage is 100%. The description need not explain parameters and does not miss anything. A baseline of 4 is appropriate as the schema already provides all necessary 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 purpose: testing AgenticBTC payments end-to-end by checking API, Lightning, channels, and liquidity. It is a specific verb-resource combination and distinguishes itself from sibling setup tools focused on configuration rather than testing.

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?

No guidance is provided on when to use this tool versus alternatives. Siblings include many setup_* tools, but there is no mention of prerequisites, sequence, or contrast with other diagnostic tools like 'setup_diagnose_issues'.

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