Check status

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds the useful behavioral fact that this is a preflight auth/identity probe with no arguments, though it doesn't state what is returned or that it performs no network mutation beyond an auth lookup.

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?

Two sentences, zero waste, with the core purpose front-loaded and the sequencing advice second. Every clause earns its place for a tool this small.

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 parameterless, non-destructive status probe the description covers purpose, sequencing and identity scope adequately. The only gap is that no output schema exists and the description doesn't say what the check returns (authenticated flag and account identity), which an agent must discover at call time.

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 the schema baseline of 4 applies; there is nothing for the description to disambiguate. No parameter text is needed or missing.

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?

States a specific check (is the caller authenticated) and a specific resource (Misar.Blog account), which is precise enough for an agent to know it will not return content. It does not explicitly contrast itself with the sibling 'login' tool, which is the nearest ambiguity, so it stops short of 5.

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?

'Run this first to verify your connection' gives an explicit ordering rule, which is real usage guidance rather than vague implication. It omits the complementary branch (what to do when the check fails, e.g. call login), so no explicit alternative is named.

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