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

With destructiveHint=true already declared, the description goes well beyond the annotation by spelling out the actual consequences: unpublish 'takes the page down' and noindex 'hides it from Google', both restricted to 'Seovyn-hosted sites only', and both requiring confirm. That is exactly the destructive-effect detail an agent needs before acting.

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?

Compact and front-loaded: scope first, then each action inline. The nested quoting around 'decide' { itemId, decision: keep | unpublish | noindex } is dense but each clause earns its place; no filler sentences.

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 5-param, no-output-schema, destructive tool the description covers scope, all three actions, decision semantics, the confirm gate, and the hosted-site restriction. Remaining gaps (org defaulting, what the list/review output looks like) are minor and partly covered by the schema.

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 coverage is 60% and the enums for action/decision carry no schema descriptions, so the description does real work by defining each action's behavior and each decision value's effect. Only 'org' is left to the schema, which documents it adequately.

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 defines the resource precisely as 'live articles that need a decision (thin, overlapping or not earning)' and enumerates the three actions, so an agent knows this is a triage/cleanup surface rather than a general article listing. It does not explicitly name the close siblings (seovyn_list_articles, seovyn_review_article) to draw the boundary, which keeps it at 4.

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?

Per-action guidance is explicit: 'list' is the default, 'review' is for looking over live articles now 'instead of waiting for the weekly pass', and 'decide' is for recording a decision. What's missing is any statement of when to prefer this tool over the sibling list/review tools.

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