rentals_v3_by_player

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

No annotations provided, so the description carries the full burden. It discloses pagination behavior (one GET, no auto paging), limits (100 rows, 256 KiB) and truncation/refusal handling, preserves numeric strings, and warns that some filters may be ineffective. Includes some noisy test observations (e.g., 'Two pages of two matched four rows'), but overall gives useful behavioral context.

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 overly long and rambling, mixing testing observations ('Two pages of two matched four rows; amount asc/desc changed the observed ordering') with operational details. Repeats the no-paging fact twice. Not front-loaded beyond the first sentence; much of the content is tangential or redundant.

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?

With 8 parameters, no annotations, and no output schema, the description should provide full parameter semantics and return expectations. It covers pagination and limits but omits explanation for offset, sort, order, and counterparty, and never describes the return structure. The warning that filters may be ineffective is not a substitute for documentation.

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 explain all 8 parameters. It only vaguely addresses role and status (e.g., 'Borrower/lender roles were checked', 'status 0 and 1'), and explicitly states that other filters are 'forwarded as supplied; their effectiveness is not implied'. Offset, sort, order, and counterparty semantics are largely unexplained or dismissed.

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 ('Read'), resource ('public SPSP delegation rental records'), and scope ('for an explicit player'). Clearly distinguishes from siblings like rentals_v3_by_role and clarifies it is token delegations, not card-worker rentals. An agent can tell what this tool does and what it does not cover.

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?

Implies when to use it: when querying rentals for a specific player. Mentions it is token delegations, not card-worker rentals, providing a distinction. However, it does not explicitly name alternative tools like rentals_v3_by_role or give a when-not-to-use condition, only indirect context.

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