m2m_get_service_status

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, covering the safety profile. The description adds scope by specifying what exact statuses are returned and clarifying exclusions, but does not disclose additional behavioral traits like output format or failure modes. With annotations present, the description adds some context but not a rich behavioral picture.

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 two sentences with no filler. It front-loads the core purpose and then immediately provides an exclusion, making it highly scannable for an agent.

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 there are no parameters, no output schema, and rich annotations, the description provides enough context for an agent to decide whether to call it and what to expect. It enumerates the three status areas and clarifies exclusions. However, the lack of output schema means the exact response format is not described, which could be a minor gap, but the description compensates by listing the data categories.

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 is empty with zero parameters, so schema coverage is trivially 100%. Per the baseline for zero-parameter tools, the description earns a 4; there are no parameters to describe, and the description adds no misleading 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 fetches operational status, upstream Base RPC quorum status, and persistence availability for M2M Sentinel infrastructure. It also explicitly states what it does not return (blockchain or market telemetry), which distinguishes it from sibling tools like m2m_get_token_price and m2m_get_dex_liquidity.

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 implicit usage guidance: it is for infrastructure health checks, not for blockchain or market data. However, it does not explicitly name alternative tools or state 'use this when you need operational status,' so the context is implied rather than explicit.

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