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

Annotations already cover readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is established. The description's 'Store' verb is confusing in light of readOnlyHint=true — it hints at a write operation for an explicitly read-only tool. Beyond that, the description adds little behavioral context (no pagination, no response shape). Not a hard contradiction, but the wording undermines clarity rather than adding value.

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 compact sentence with no filler, and the flagging criteria are stated up front. It earns a high conciseness score, though the misused verb 'Store' slightly undercuts the efficiency.

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?

Parameters are fully documented and an output schema exists, so the main call-time details are covered. However, the description doesn't explain what 'running' the audit entails or how results are shaped beyond the schema, and for an audit tool some prose on returned findings would help. Adequate but minimal.

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 the schema fully documents limit, stale_days, and min_body_chars with defaults, bounds, and purposes. The description adds zero parameter-level detail, so it rests entirely on the schema — the correct baseline for full coverage.

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The description identifies the resource (pages) and the flagging criteria (content thinness, unpublished status, staleness), which distinguishes it from seo/content-related siblings like run_seo_metadata_audit. However, the verb 'Store' is vague and misleading for an audit tool — it doesn't clearly say the tool analyzes/returns flagged pages. The name suggests 'audit' but the description never confirms the evaluation or reporting behavior.

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 description states what pages get flagged but gives no when-to-use or when-not-to-use guidance, no alternatives, and no prerequisites. An agent cannot tell from the description when to pick this over run_seo_metadata_audit or run_product_completeness_score beyond guessing from the criteria.

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