bind_serve_stale_status

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

Annotations already declare readOnlyHint=true, and the '[READ]' prefix merely restates that rather than adding context. The description says nothing about whether the result reflects configuration vs runtime counters, whether it requires a live server connection, or how the answer is presented — and there is no output schema to fall back on.

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?

One short, front-loaded sentence with no filler; the key concept (stale DNS answers) appears immediately. Minor waste in the '[READ]' tag, which duplicates the readOnlyHint annotation.

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 output schema, the description carries the burden of explaining what comes back, but it does not say whether the tool reports enablement, active serve-stale responses, or counts. Combined with an undocumented 'target' parameter, the definition is too thin for correct invocation.

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 single optional parameter 'target' has 0% schema description coverage and is never mentioned in the description. An agent cannot tell whether target means a server, a view, a zone, or a network endpoint, and the description does nothing to compensate for that gap.

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 verb-plus-resource is concrete: 'Show whether stale DNS answers are currently served' names the specific BIND serve-stale feature state being queried. It is distinguishable from most siblings (zone transfers, timeouts, keys), though it does not explicitly contrast with adjacent status tools like bind_status or bind_zone_status.

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?

There is no guidance on when to call this versus the many other status siblings, no note on prerequisites (is serve-stale required to be enabled/configured first?), and no exclusions. The agent must infer usage entirely from the name.

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