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

readOnlyHint=true already establishes this is a safe read. The description adds genuine domain context (bounty paid in recognition days, awarded on accepted answer, distinct from free access) that is not in the annotations, but says nothing about the tool's own behavior — result size, ordering, pagination, or freshness.

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, front-loaded with the core definition and reasonably tight. The trailing clause about the award not being access is useful framing but drifts toward lore rather than invocation guidance.

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?

With no parameters, no output schema and only a readOnly hint, the definition is nearly complete for a simple listing tool, but it never states what comes back (all quests? open only?) or any limits. A single clause on the returned set would close the gap.

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 baseline is 4. There is nothing parameter-related the description could add, and it introduces no contradictory signature hints.

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 defines the resource ('Open questions with a bounty in recognition days') but never states the operation — it is implied that this returns the collection, yet the verb is absent. It also does not distinguish quests from lookalike siblings such as project100_requests or project100_request_answer, which an agent could easily confuse with open questions.

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 explains the reward mechanic behind quests, but gives no explicit when-to-use guidance and names no alternatives. Nothing tells the agent whether this is the tool to browse quests versus project100_quest_answer to act on one, or how it differs from project100_requests.

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