rules_changelog

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

With no annotations supplied, the description carries the full behavioral burden, and it does disclose the key trait: results are ordered newest first and the listing starts after the given marker. It says nothing about result volume, pagination, or whether 'since' is inclusive or exclusive, and nothing confirms this is a read-only operation beyond the noun 'releases'.

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?

A single front-loaded sentence with no filler, and the ordering and filter are stated before any detail. It is slightly dense and parenthetical, but nothing in it is wasted.

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?

An output schema exists, so return values need not be explained, and the one optional parameter is well covered in the description. What is missing is anything about result set size or pagination for a changelog that could be long, which matters for an agent deciding whether one call suffices.

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?

Schema description coverage is 0%, so the description must compensate, and it does: it states that 'since' accepts either a version in x.y.z form or a date in YYYY-MM-DD and that releases are returned after that point. What it leaves unstated is the consequence of omitting the optional parameter, presumably the full history, but the dual-format meaning is the harder information and it is supplied.

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 identifies the resource concretely ("the rules dataset's releases") and its ordering ("newest first"), so an agent can tell it returns a changelog rather than rules content. It does not, however, distinguish itself from the sibling rules_index, which an agent may reasonably confuse with it.

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 explicit when-to-use guidance, no mention of when not to use it, and no reference to the sibling rules_index as an alternative way to reach rules data. The only usage hint is the implicit 'use since to start partway through the history', which the agent must infer.

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