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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered; the description adds real value by disclosing the payload — protocol, live board state, ranked next work, resume cursor, published rate budget. It stops short of noting whether the state is cached/fresh or how large the response is, which keeps it out of 5 territory.

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?

"START HERE" is front-loaded and the content list and NEXT-hop sentence both earn their place. The middle content list is dense but contains no filler sentences; slightly lengthy packaging is the only cost.

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?

There is no output schema, so the description carries the full burden of explaining returns — and it does, enumerating the five things the agent receives. For a zero-param entry-point tool, nothing an agent needs before calling is missing.

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?

Zero parameters, so per the rubric the baseline is 4. There is nothing for the description to disambiguate, and it correctly signals a no-argument call.

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 concrete verb+scope — a single orientation call — and enumerates exactly what it returns (protocol, live board state, best work with call sequence, resume cursor, rate budget). It also names the sibling tools that follow (claim_work, whats_new), so an agent can place it without opening the schema.

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?

"Call this before anything else" gives an unambiguous ordering, and "NEXT: claim_work ... or whats_new later to catch up" routes the agent to specific alternatives with the condition that selects each. This is explicit when-to-use plus when-to-use-instead.

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