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

The description goes well beyond the annotations by disclosing that the tool BLOCKS until human action, that force=true ROTATES and invalidates existing keys, that an existing valid session returns immediately without changes, and that it listens on a short-lived local port. These are critical behavioral traits. There is no contradiction with the annotations.

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 front-loaded with a clear one-sentence purpose, then usage conditions, then critical warnings. Each paragraph earns its place, and nothing is redundant with the schema. The entry is moderately long but all pieces are necessary for safe invocation.

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 description fully covers the success flow, key storage location, blocking behavior, force semantics, port selection, and base_url handling. It does not explicitly state what happens if the user cancels or fails to respond, nor the exact return value format, but the absence of an output schema makes this a minor gap. Overall the agent has enough context to invoke the tool appropriately.

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?

Even though the schema already provides 100% parameter coverage, the description adds behavioral nuance: force=false does not change anything if already authenticated, the port is where the short-lived callback listener runs, and base_url should be omitted for the hosted service. This enriches the schema's semantic values rather than just repeating parameter names.

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: 'Connect a Misar.Blog account by browser consent', specifying the verb, resource, and unique method. This distinguishes it from all sibling tools, which are post-reading/publishing/analytics operations, not authentication.

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?

It gives explicit when-to-use conditions: 'Use it when status reports no key, or when a tool fails as unauthenticated.' It also gives strong when-not-to-use guidance: 'never call it speculatively or in a retry loop.' No alternatives are named, but no other sibling provides this function, so the guidance is sufficiently clear.

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