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

Annotations already declare this a safe, idempotent, closed-world read, so the description's job is to add context — and it does, disclosing sort order, the per-item record shape (date, status, source links), and the status taxonomy (official/reported/community). It stops short of saying whether the list is curated/static or how large the corpus is, so not a 5.

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 sentence, front-loaded with the resource and ordering, with no filler. Every clause (ordering, status values, source links) carries information the agent would otherwise have to discover.

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 takes on return-shape disclosure and does it well for a simple, single-optional-parameter read tool. The only residual gap is whether the timeline is a fixed curated set or refreshed, which affects how an agent should present results.

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 100% and the single parameter already explains 'newest first' and its bounds. The description's mention of 'newest first' merely echoes the schema rather than adding meaning, so the baseline 3 applies.

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 names the resource precisely (major GTA VI announcements) and its ordering (newest first), which cleanly separates it from siblings like get_game_info or get_launch_info. The verb is only implicit ('announcements... each with'), so it reads as a content summary rather than an explicit retrieval action, keeping it just below a 5.

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 statement of when to use this tool versus get_launch_info, get_game_info, or any other sibling, and no preconditions or exclusions are given. The agent must infer usage purely from the resource name.

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