register_visitors_from_file

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

With no annotations, the description carries the full behavioral burden. It does disclose the important mutation-control trait (dry_run=true means nothing is submitted) and the column-fallback rule, which is genuinely beyond the schema. It is silent on permissions, row-level validation/error behavior, duplicate handling, and whether partial failures roll back.

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?

Core behavior is front-loaded in the first sentence, with the date/time fallback and dry_run clause following in tight order. The trailing keyword block is long but functional for retrieval; little is wasted otherwise.

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. For a 7-parameter bulk mutation tool with zero annotation coverage, though, the description should say more about expected file columns and what happens to invalid rows; three parameters and the failure model remain undocumented.

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%, so the description must compensate. It explains default_visit_date/default_visit_time (and dry_run), roughly half the parameters, but leaves default_floor, default_purpose, and participation entirely undefined in both description and schema, so the agent cannot tell what values those accept or what they default to semantically.

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 a specific verb+resource (bulk-register visitors read from a file) and enumerates the accepted formats (Excel/CSV/TSV), which cleanly separates it from the single-visitor sibling register_visitor and from the text-based register_visitors_from_text. It never names the preview counterpart preview_visitors_from_file, so sibling routing is implied rather than explicit.

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?

Gives two concrete usage conditions: supply default_visit_date/default_visit_time when the file lacks date/time columns, and dry_run=true to avoid submission. However it never states when to prefer this over preview_visitors_from_file or register_visitors_from_text, and no prerequisites are mentioned.

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