get_latest_manifest

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

The description discloses recursive search behavior and file type filter (CSV with 'manifest'), but no annotations exist. It does not specify error handling (e.g., if no manifest is found), authentication needs, or whether the output is just a path or includes content. These are gaps for a mutation-free read tool.

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: two sentences plus an args section. Every part is relevant, no extraneous information. It is front-loaded with the main action.

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 tool's simplicity (one parameter, straightforward operation), the description covers the core functionality and search strategy. The presence of an output schema reduces the need to document return details, but missing error scenarios slightly lower completeness.

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 lone parameter 's3_path' is described with an example and clarification that it is the path to search. Since schema description coverage is 0%, the description adds meaningful context beyond the bare 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 tool name and description clearly state it retrieves the latest manifest file path from an S3 bucket. The description specifies recursive search for CSV files containing 'manifest', distinguishing it from siblings like browse_s3 or validate_manifest.

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 usage when the latest manifest path is needed, but does not explicitly state when to use versus alternatives (e.g., browse_s3 for listing files, validate_manifest for validation). No when-not-to-use guidance is provided.

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