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

Adds genuinely non-obvious behavior beyond the annotations: the draft is marked ready, a thread link is returned, and no post occurs. This meaningfully qualifies the destructiveHint=true declaration, which would otherwise suggest content is removed. It does not, however, say what state transition happens or whether approval is reversible.

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, zero redundancy, and the key behavioral constraint ('Soclo does not post it') is placed where it will be read.

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?

With no output schema, the description correctly supplies the return value (thread link). For a single-parameter tool it is nearly complete, though it omits error conditions and whether approval can be undone.

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?

Only one parameter, replyId, and the schema provides zero description coverage for it. The description's phrase 'a draft' hints that replyId identifies the draft, but it never states the expected identifier or where to obtain it, so it does little to compensate for the coverage gap.

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 concrete verb and resource (mark a draft ready) and immediately clarifies the scope by noting Soclo does not post the reply. That distinguishes it from posting siblings like soclo_inbox_reply and from soclo_conversations_reply_posted, though no sibling is named explicitly.

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 phrase 'so the owner can open it and post the reply themselves' implies the use case (handing off to a human), but there is no explicit when-to-use rule, prerequisite (draft must exist), or named alternative such as reply_edit or reply_posted.

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