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

With no annotations, the description carries the full burden, and it does disclose the authentication requirement and where to obtain a key, which the schema does not cover. It says nothing about what filing actually does behaviorally: whether the story publishes immediately, whether it is reviewable/editable after submission, or whether repeated calls create duplicates.

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?

Three short, front-loaded sentences with no padding; purpose leads, requirements follow, auth last. Some of the content (required fields, optional Spanish) duplicates what the schema already declares, which is minor waste in an otherwise tight definition.

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?

For a 13-parameter mutation tool with no annotations and no output schema, the description is thin: it never says what happens after filing, what the response looks like, or how the existence of get_filing_status relates to this tool. A submitting agent is left guessing about the lifecycle of the created story.

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%, so all 13 parameters are already documented in the schema, including the optional-Spanish translation behavior and the sources format. The description adds no syntax, format, or constraint detail beyond restating that English title and body are required, so the baseline of 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?

States a specific verb and resource ('Create a filing') and the tool name/title ('File a story') make the subject matter recognizable, so an agent can distinguish it from the read-only sibling get_filing_status. However, the mismatch between 'filing' in the description and 'story' in the name/title introduces minor ambiguity, and no sibling is named explicitly.

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?

The description states prerequisites (authentication, key request URL) and required inputs, but gives no guidance on when to file versus when to check get_filing_status, no indication of what qualifies as fileable content, and no exclusions. Usage must be inferred.

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