Connect S3 media bucket

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

Annotations already indicate write, open-world, non-destructive behavior. The description adds context by listing scaffold components and mentions 'credential/signing safety notes', which hints at auth handling. However, it does not clarify whether the tool actually connects to an external S3 service or just creates a local scaffold, leaving a behavioral gap.

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, well-front-loaded sentence with no redundant words. It efficiently conveys the core purpose and key elements, earning its place without any fluff.

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 10 parameters, no output schema, and only sparse annotations, the description is too short to fully inform an agent. It lacks crucial details such as whether an actual S3 connection is established, how credentials are handled, or what the scaffold's manifest and cache policy entail. The tool is complex enough to require a richer description.

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 only 20% (2 of 10 params described). The description does not map its mentioned features (e.g., 'cache policy', 'adapter source') to specific parameters like cache_policy or adapter_mode. It provides minimal semantic help; the burden falls on the schema, which is mostly undocumented.

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 uses a specific verb ('Create') and clearly identifies the resource ('S3-compatible media-bucket scaffold') and key deliverables ('manifest rows, cache policy, ingest status, adapter source, credential/signing safety notes'). This distinguishes it from sibling tools, which are mostly about other connections or scene creation.

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 implies the tool is used when you need to set up an S3-compatible media bucket, but it does not explicitly state when to use it vs alternatives, nor does it mention prerequisites or exclusions. Context is clear but guidance is not explicit.

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