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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered externally. The description adds no behavioral context of its own — nothing about pagination, result volume, or whether 'pending' means unapproved or unscheduled. The claim of a GET read operation is consistent with annotations, so no contradiction.

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 first two sentences are identical duplicates — pure waste. The only content-bearing clause is the operation ID and the describe_operation pointer, and none of it is front-loaded meaningfully.

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?

No output schema exists, so the description would need to characterize the return shape of a list endpoint, and it does not. For a tool with a nested-object query parameter and zero schema documentation, an agent is left unable to call it correctly without first consulting describe_operation.

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?

Two parameters (query, params) exist with 0% schema description coverage, so the description must compensate and does not. Pointing to describe_operation and 'native request schemas' offers a route to the information but supplies no meaning for the generic query object or the empty params object.

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 is a verbatim repeat of the endpoint path 'GET /api/modifications/pending', which is already the title. It implies retrieval of pending modification records but never states in plain language what the tool returns or how it differs from the sibling get_leases_by_leaseId_modifications or get_modifications_by_modificationId.

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?

No guidance on when to use this versus alternatives. The only actionable cue is the pointer to describe_operation for request schemas, which is a schema-lookup hint rather than a usage condition or exclusion.

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