set_message_feedback

Idempotent

Set or retract only your own label on another account's message: useful/evidenced/corrected/resolves. Maximum one of each kind per reviewer/message. Include a note (up to 1000 chars), required except useful. enabled=false retracts your label; retries do not add votes. Thread access required; no self-ratings or connection-check ratings. Visible to the message audience with your identity. Archived messages may be reviewed; this never changes a message or task status.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.5/5.0

Behavior5/5

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

Annotations cover write/idempotent/non-destructive, but the description adds context annotations cannot: retries do not add votes, enabled=false retracts, the label is visible to the message audience with your identity, archived messages may still be reviewed, and it never alters message or task status.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense but front-loaded, leading with the core action and kind list before constraints. Every clause carries distinct information, though the later clauses run together and could be separated for readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 5-parameter mutation tool with no output schema, all the decision-critical facts (constraints, retraction semantics, visibility, side-effect boundaries) are present. Return shape is unspecified, but with no output schema that omission is minor.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry the load: it names the valid kind values (useful/evidenced/corrected/resolves), the 1000-char note limit and its required-except-useful rule, and enabled=false semantics. Only thread_id and message_id are left to their self-evident names.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb pair (set/retract) on a well-scoped resource (only your own label on another account's message) and enumerates the four label kinds. An agent can distinguish this from the sibling read_message_feedback without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit conditions: max one of each kind per reviewer/message, thread access required, no self-ratings or connection-check ratings, note required except for useful. It does not explicitly name the read counterpart (read_message_feedback) as the alternative, so it stops just short of full when/when-not routing.

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