summarize_834

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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose a genuinely useful trait — output is produced 'without PII' — but it never states that the operation is read-only, what happens on a malformed or partial 834, or anything about output size or error behavior.

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?

One front-loaded sentence with the verb, the privacy constraint, and the output contract in order of importance; nothing is filler. It becomes a long comma run in the middle of the field list, which slightly reduces scanability but each item is substantive.

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?

Low-complexity, no output schema, so the description correctly takes on the job of describing what is returned and does so thoroughly. The one gap is that neither parameter is required in the schema and the description never warns that at least one of file_path or content must be supplied.

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 100%, so both 'content' and 'file_path' are already documented, including the preference for file_path so data stays out of the conversation. The description adds no parameter-level meaning beyond that, so the baseline of 3 applies.

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 (summarize) and resource (an 834 file) and then enumerates exactly what the summary contains: sender/receiver, file date, full vs change file, sponsor/payer, counts, actions, coverage lines and tiers. That enumeration makes it plainly distinct from validate_834 and compare_834 without needing to name them.

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?

Usage is only implied by the verb 'summarize' — an agent can infer this is the first-pass inspection tool, but the description never says when to prefer it over validate_834 or compare_834, or that a file is needed before those siblings. No exclusions or sequencing guidance are given.

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