parse_xer_file

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

No annotations are provided, so the description carries full burden. It indicates a read-only parse operation returning basic data, but lacks details on side effects, performance implications for large files, or error handling. The list of returned items gives some transparency.

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 efficiently conveys the action and output, with no redundant words. However, it could be improved by front-loading the action more explicitly.

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 one parameter and no output schema, the description provides a useful list of returned data types but lacks detail on data structure or that parsing is a prerequisite for sibling query tools. The agent may need additional context to fully utilize the output.

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 single parameter `file_path` has 0% schema description coverage, and the description adds no semantics beyond its name. It does not clarify path format, required file existence, or supported storage locations, leaving the agent to infer.

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 clearly specifies the action: parse a Primavera P6 XER file. It lists the specific information returned (project list, status breakdowns, activities, resources, etc.), distinguishing it from sibling tools that query already parsed data.

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 this tool is used as a first step to load project data, but it does not explicitly state when to use it versus alternatives (e.g., when data is not yet parsed) or provide any exclusion conditions.

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