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

Annotations already establish the safety profile (not read-only, not destructive, idempotent, closed-world), so the bar is lower. The description does add an authorization constraint — only stories owned by the connected account can be renamed — which is genuine context beyond annotations, but it omits the fact that a user-approved flag is mandatory for the call to succeed.

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 zero filler. It is efficient, though its brevity also means it under-specifies the operation relative to what the tool requires.

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 annotations covering safety and the schema documenting the required approval flag, the core is present. However, for a mutation tool with no output schema, omitting the mandatory user-approval prerequisite and any title constraints leaves an agent with a partially complete picture.

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 coverage is only 33%: the schema describes approvedChange well but leaves title and storyId undocumented. The description implies that 'title' is the new value and 'story' identifies the target, but adds no format, uniqueness, or constraint detail to compensate for the coverage 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?

States a specific verb (change) and targeted field (title) on a clearly identified resource (a story), and adds the ownership scope 'owned by the connected account'. It does not explicitly differentiate itself from siblings like replace_story_page_text or create_story, but the operation is unambiguous.

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?

No when-to-use guidance and no mention of alternatives. An agent gets no signal about when renaming is appropriate versus using replace_story_page_text, or what preconditions must hold. Usage is only inferable from the name.

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