v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: it does not say whether the alias is fully equivalent to hpe_fill_slots, whether it is deprecated, or whether output is identical. For an alias tool the key behavioral fact is the equivalence and deprecation status, and neither is stated.
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?
A single short sentence with no filler, and the alias relationship is front-loaded. It is efficient, though the brevity is partly under-specification rather than pure conciseness.
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?
An output schema exists, so return values need not be explained, and as a thin alias the description is arguably adequate. Still, an agent deciding between this and hpe_fill_slots needs deprecation/equivalence guidance that is missing, and the 0%-documented parameters are unaddressed.
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 description coverage is 0% across 4 parameters (pdf_path, output_path, page_number, operations_json), and the description adds no parameter meaning at all. The alias reference weakly implies the parameters mirror hpe_fill_slots, but that requires the agent to consult another tool's docs and is not stated.
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?
"Backward compatibility alias for hpe_fill_slots" tells the agent this tool is a duplicate of a named sibling, which aids disambiguation, but it never states the actual verb+resource — filling slots in a PDF page. The purpose is only inferable by looking up the canonical tool.
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 word "alias" plus "backward compatibility" implicitly signals this is for legacy callers and that hpe_fill_slots is the preferred entry point, which is useful routing. However it never explicitly says "prefer hpe_fill_slots" or states whether this tool is deprecated or scheduled for removal.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
