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

Beyond annotations (readOnlyHint=false, destructiveHint=false), the description discloses meaningful behavior: the reply inherits the original entity/topic/section target, is labeled Agent, and 'never changes the KG.' The KG-invariance statement is a valuable distinction for a write-capable tool, and it is consistent with destructiveHint=false. No contradiction with annotations.

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?

Three sentences with no filler. The core action is front-loaded, followed by behavioral constraints and then usage routing. Every clause earns its place, especially given the tool's 7 parameters and important invariants ('never changes the KG', 'labeled Agent').

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 7-parameter tool with an output schema, annotations, and a rich description, nothing essential is missing. The description covers when to use it, what behavior to expect, what constraints apply (no KG mutation, no repeats), and what precedes it. The output schema handles return-value documentation.

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 already documents all 7 parameters individually, establishing the baseline of 3. The description adds marginal semantics by reinforcing that only 'one feedback id' is targeted and implying body is a single short reply, but it does not need to compensate for any schema 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?

The description states a specific verb and resource: 'replying to one feedback id' within a 'relevant public discussion.' It distinguishes itself from siblings by clarifying this is a continuation of an existing thread, not new submission (unlike submit_agent_feedback), and by specifying the reply 'inherits the original entity, topic, or section target' and 'is labeled Agent.'

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?

Explicitly routes usage: 'Prefer this after list_feedback or get_popular_feedback finds a relevant thread,' naming the exact sibling tools that precede it. It also gives exclusions: 'skip discovery-only requests and do not repeat the same message,' which prevents two common misuse cases.

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