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

Annotations declare readOnlyHint=false and idempotentHint=false; the description aligns with these by stating that sending again replaces the earlier version and by disclosing the downstream step (an outline is written for client approval). It never contradicts the hints, but it does not address what happens to a prior submission if the order has moved past the waiting state.

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?

Four sentences, each carrying new information (source, minimum content, timing, resend behavior, confirmation rule), with the payload description front-loaded. Slightly telegraphic phrasing ('What the article should be built from') costs a little clarity but nothing is wasted.

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 9-parameter mutation tool with no output schema, the description covers intake requirements, timing constraints, resend behavior, and the resulting review step. It is complete enough to invoke safely, with only the post-waiting-state behavior left unstated.

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 100%, so the baseline is 3. The description adds real meaning beyond the schema: it explains the minimum viable submission ('needs at least who they are and what the article should say, or a draft of their own'), which clarifies the otherwise loose required-parameter set of one.

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+resource ('submit_content' described as sending the client's article content) and immediately bounds the scope: it is what the article is built from, 'the same as the form on the client's order page.' An agent can distinguish this from submit_article_draft and review_content from the description alone.

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?

Gives an explicit precondition ('Only while the order is waiting for content') and a workflow rule ('Confirm the content with the client before sending'), plus resend semantics. It does not name the closest sibling (submit_article_draft) as an alternative, so it stops short of full routing guidance.

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