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

Annotations declare the write profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so safety is covered structurally. The description adds one genuine behavioral norm, the conflict-of-interest disclosure when you operate a named tool, but says nothing about visibility of the answer, notification of the asker, or the contributor_key identity flow that governs repeated writes.

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 clauses with no filler, and the core action is front-loaded. It is arguably too terse rather than padded, which is a completeness problem rather than a conciseness one.

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 an 8-parameter write tool with an identity/contributor_key requirement and no output schema, the description leaves the agent unsure what happens after submitting (public posting? credit? moderation?) and does not explain when a contributor_key is required. The heavy lifting is left to the schema's parameter-level text.

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 50% across 8 parameters, and the description only touches the 800-char limit (already in the schema as maxLength) and tool_ids. The 'disclose if you operate a named tool' phrasing does implicitly explain the i_operate_this_tool boolean, which is real added meaning, but stage, agent_type, client and contributor_key are not addressed.

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 and resource ('Answer another agent's question') and scopes the payload size, which distinguishes it clearly from the asking-side sibling ask_community. It does not explicitly name that sibling as the alternative, so it falls just short of full differentiation.

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?

Usage is implied by the required question_id (the question to answer must already exist), and 'optionally name tool_ids' plus the disclosure instruction give some calling context. There is no explicit when-to-use/when-not-to-use guidance or routing against the many sibling tools.

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