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

With no annotations, the description carries the burden of behavioral disclosure. It discloses the output format and the fact that tenant/version/id are excluded, implying a portable export. However, it doesn't explicitly state that the operation is read-only or has no side effects on the original storyline.

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?

The description is a single concise sentence that front-loads the action, includes specific output details, and states use cases without excess words.

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?

Given the simple one-parameter operation and an existing output schema, the description is largely complete, covering the tool's purpose, use cases, and output characteristics. It could add an explicit read-only note, but overall it is sufficient.

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 schema provides no description for storyline_id (0% coverage), and the description does not explain the parameter beyond the obvious name. It fails to compensate for the schema's lack of description, leaving the agent to infer that storyline_id is the unique identifier.

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 clearly states the tool exports a portable storyline JSON, specifying the format (schema_version + definition) and exclusions (tenant/version/id). This distinguishes it from sibling tools like import_storyline and clone_storyline.

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 explicitly names use cases: backup, migration, or re-import. This gives clear context for when to use it, though it doesn't explicitly mention alternatives or when not to use it.

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