update_package_expiration_date_and_time

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

The description discloses that expired packages and files are deleted permanently, which is critical behavioral information. It does not cover authorization, rate limits, or other side effects. With no annotations, it partially fulfills transparency but leaves some gaps.

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 concise with three sentences, front-loading the main purpose. Each sentence adds essential information (action, storage toggle, consequences), with no unnecessary 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?

The description covers the main action, parameter relationships, and the critical consequence. However, it lacks information on return values (no output schema), usage guidelines, and prerequisites, making it partially complete for the tool's moderate complexity.

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 input schema has 100% description coverage. The description adds value by clarifying that unlimited_storage enables/disables storage and stating the constraint that expiry requires unlimited_storage to be false, going beyond the schema.

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 it updates expiration date/time and toggles unlimited storage, using a specific verb and resource. It distinguishes from sibling tools like delete_package or get_package by specifying the update action on expiration and storage settings.

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 provides context about charges and permanent data loss on expiration, helping the agent understand impact. However, it does not explicitly state when to use this tool versus other package-related tools, nor does it mention alternatives or prerequisites.

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