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

Annotations cover the safety profile (not read-only, open-world, non-idempotent), so the description correctly focuses on what they cannot convey: that this only starts the flow and returns an authorization_url the user must open in a browser. That workflow detail is genuinely additive, though it omits what happens if the flow is abandoned or that repeated calls yield fresh URLs.

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, both front-loaded and purposeful: the first defines the action, the second defines the return value and required user follow-up. No filler or restatement of the title.

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 tool with no output schema and full annotation coverage, the description supplies the essential missing piece — the authorization_url return value and the browser step. It stops short of describing post-authorization behavior or how to verify the connection succeeded, which would make it fully self-contained.

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 per the rubric the baseline is 4. There is nothing for the description to disambiguate, and it correctly avoids inventing parameter detail.

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 states a specific verb and resource — 'Start the OAuth flow for a LinkedIn profile account' — which pins down both the action and the platform. Against siblings like chirpie_connect_bluesky or chirpie_connect_x, the platform-specific naming makes it unambiguous which tool to pick.

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 implies when to use it (to initiate a LinkedIn connection) and describes the follow-up step the user must take, but it names no alternative or exclusion — e.g., whether an existing connection should be checked via chirpie_list_accounts first or how this differs from chirpie_disconnect_account. Usage is inferable but not guided.

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