Connect S3 media bucket

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

Beyond annotations (readOnlyHint=false, openWorldHint=true, destructiveHint=false), the description adds meaningful behavioral context by mentioning 'credential/signing safety notes' and 'adapter source', signaling important security and integration details. It does not contradict the annotations and provides extra depth about the scaffold's contents.

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 sentence that front-loads the primary action and resource, then lists included features. It is concise and efficient, though slightly dense with compound items; overall no wasted 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?

With 10 optional parameters and no output schema, the description captures the scaffold's purpose and key components, but it lacks guidance on configuration choices and the meaning of several parameters. It is adequate as a high-level summary but not complete enough for an agent to confidently decide how to use the tool without additional schema exploration.

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% (name and parent_path), so the description must compensate for the other eight parameters. It references cache_policy, adapter_mode, and manifest-related concepts, but it does not explain parameters like provider, prefix, or active. The vague term 'ingest status' does not map directly to a schema field, so parameter meaning remains under-specified.

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 the specific verb 'Create' and clearly identifies the resource as an 'S3-compatible media-bucket scaffold'. It enumerates constituent elements (manifest rows, cache policy, ingest status, adapter source, credential/signing safety notes), making it distinct from sibling connect_* tools that target different systems. The purpose is unmistakable.

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 use when an S3 media-bucket scaffold is needed, but it offers no explicit when-to-use or when-not-to-use guidance. It does not name alternatives or exclusions, leaving the agent to infer applicability from the name and description alone.

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