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

With no annotations provided, the description carries the full burden; it does disclose the permission requirement and the pagination ceiling (max 100), which are real behavioral facts. It stops short of clarifying what 'unused' means, whether counts are grouped in the response, or how large a pantry can be, which matters for a read tool with no output schema.

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?

Two short sentences with the core purpose front-loaded, then the permission and pagination facts. Slightly telegraphic ('Requires play permission; offset/limit...') but no wasted clauses.

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 annotations and no output schema, the definition covers invocation adequately but leaves the return shape thin — 'counts by type' does not tell the agent what fields an entry has or how truncation manifests.

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 carry parameter meaning — and it does name both limit and offset and frames them as pagination, with the default 25 and max 100 called out. Some of this duplicates schema defaults/maximums, but the framing as offset/limit pagination is genuine added meaning.

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 resource (unused garden harvest ingredients) plus the return shape (counts by type), which is more than a restatement of the name kitchen_pantry. It does not, however, distinguish this from close siblings like inventory, ingredient_catalog, or garden_status, leaving the agent to guess which list is which.

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 one prerequisite stated — 'Requires play permission' — is useful, and 'unused' hints at the filter scope. But there is no explicit guidance on when to pick this over inventory or ingredient_catalog, so the agent must infer the boundary.

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