microsoft_download_file

Read-onlyIdempotent

Download a specified file from Microsoft using the project-bound connector account, routing through the governed connector authority for authenticated access.

Instructions

Microsoft connector operation download_file (platform tool microsoft.download_file).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the operation routes only through the exact project/account governed connector authority and that `effect` must be 'read' and is verified by Spring, which is useful but does not go further into request/response behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loads the operation identity and routing constraint. The argument list is organized and terse, with little wasted wording, though some phrasing like 'Microsoft connector operation' and 'platform tool' is slightly redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is incomplete for a 7-parameter, 0%-schema-coverage tool. It fails to explain what to place in the `arguments` JSON, what file is being downloaded, how to reference it, or what output to expect, despite the presence of an output schema. The annotation-provided safety profile helps, but the operational specifics needed for correct invocation are largely absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry the burden of explaining parameters. It provides brief meanings for `project_id`, `project_ref`, `connector_account_ref`, `idempotency_key`, and `effect`, but the central `arguments` parameter is only described as a 'JSON string of arguments' with no indication of what keys or values the download operation requires, such as file identifiers or paths. This leaves the agent without enough information to correctly invoke the operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies a specific operation (`download_file`) on the Microsoft connector and names the platform tool (`microsoft.download_file`). The verb and resource are clear from the tool name and description, though the description does not explicitly state 'downloads a file from Microsoft' or differentiate it from sibling Microsoft tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like `microsoft_list_drive_files`, `microsoft_upload_file`, or `microsoft_update_file`. The only contextual statement is about routing through the governed connector authority, which explains a constraint but not when the tool should be selected.

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