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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds the organisation-scoping constraint, which corroborates openWorldHint=false, but says nothing about ordering, pagination behavior, or what a default (unfiltered) call returns.

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 sentence with zero filler, front-loading the resource and its scope before the optional filter. Every clause earns its place.

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?

For a two-parameter read-only list tool with no output schema, the definition is minimally serviceable: it explains the filter but not the `limit` semantics, the default result set size, or the return shape. Adequate but with clear gaps an agent would need to discover by trial.

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% and neither parameter has an enum, so the description carries real weight here: it enumerates the valid status values (sealed | active | flagged | retired) that the schema omits entirely. However, the `limit` parameter is never mentioned, leaving half the inputs unexplained.

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 (List) and a precisely scoped resource (this organisation's chip-bound graded items), which separates it from the singular detail tool `graded_item` and the mutating `bind_graded_item`. It stops short of explicitly naming siblings, so an agent must infer the relationship rather than being told it.

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 only usage hint is 'optionally by status', which is really a parameter note rather than routing guidance. There is no statement of when to reach for this versus `graded_item`, `list_sandbox_chips`, or `find_unit`, and no prerequisites or exclusions are given.

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