sharepoint_read_file

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

No annotations are provided, so the description carries the full burden. It signals a read-only operation and constrains input to text files, which is useful. However it says nothing about permissions/auth requirements, file-size limits, encoding handling, or what happens with binary or missing files.

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?

It is short, but only because the sentence is truncated mid-thought ('`file` its path...'). An incomplete sentence does not earn its place; it leaves the reader guessing at the missing clause.

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?

For a no-annotation, no-output-schema read tool, the description would need to explain inputs, return content, and failure modes. Instead it is a fragment that references parameters absent from the empty schema, so an agent cannot confidently construct a call.

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?

Parameter count is 0, which normally sets a baseline of 4, but the description refers to `library` and `file` arguments that do not exist in the schema — the call signature is inconsistent with the structured definition. It does add provenance meaning (library obtained from sharepoint_list_files) but the mismatch undermines confidence.

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?

Specific and sibling-aware, but the truncated ending weakens it.

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?

It implies a workflow by noting that `library` comes from sharepoint_list_files, which tells the agent to list first. There is no explicit when-not guidance, no mention of alternatives such as file_read/onedrive_read_file, and no statement about which files (text only?) are in scope beyond the passing phrase 'text file'.

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