read_assignment_feedback_file

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

Annotations already convey idempotence and non-destructiveness; the description adds that only the current user's response determines the feedback owner and that the attachment is published. However, the non-read side effects implied by 'index' and 'download' are not explained despite readOnlyHint=false.

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?

Two sentences with purpose front-loaded; every clause earns its place. There is no filler or redundant restating of the tool name.

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 no output schema and six parameters, the description leaves optional behavior (offset, download, maxChars) unexplained and does not describe what the tool returns in read versus download/index modes. It covers basic call prerequisites but not enough for confident invocation of all modes.

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 covers only 3 of 6 parameters (50%), and the description compensates only for file/course/assignment IDs via 'Exact Brightspace numeric identifier from another tool' plus the get_assignment_feedback source. offset, download, and maxChars remain undocumented in both schema and description.

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?

States three specific actions ('Read, index or download') on a clearly named resource ('published feedback attachment') and identifies the ID source ('File IDs come from get_assignment feedback'). This distinguishes it from sibling attachment readers such as read_assignment_attachment or read_announcement_attachment.

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?

Provides clear context for when to use it: reading published feedback attachments for assignments or group assignments, with a prerequisite ('File IDs come from get_assignment feedback') and owner scoping. It does not explicitly name alternatives or exclusion conditions, so it falls short of a 5.

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