Instructions

Slack connector operation me_message (platform tool slack.me_message).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Claimed read or write effect; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

D1.3/5.0
Behavior2/5

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

Annotations indicate destructiveHint true and idempotentHint true, but the description does not disclose any side effects or destructive potential. The 'effect' parameter mentions a claimed read or write effect, but the description never explains the actual behavior or consequences. This lack of disclosure leaves the agent unaware of risks.

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

Conciseness2/5

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

The description is short but not concise in a useful way; it repeats generic routing language without conveying substantive information. Every sentence is vague boilerplate, so brevity does not aid clarity. It reads more like a template than a purpose-built description.

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

Completeness1/5

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

The tool lacks any context about its intended Slack operation, expected arguments, or relationship to sibling tools. Although an output schema is mentioned in the signals, it is not provided in the description, so the agent cannot infer return behavior. The description is wholly insufficient for correct invocation.

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

Parameters1/5

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

Schema coverage is 0%, and the description provides no explanations for any of the seven parameters. The 'arguments' field is a JSON string whose contents are undefined, and the other parameters are generic context fields without meaning. The description fails to compensate for the missing schema details.

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

Purpose1/5

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

The description is entirely boilerplate and does not state what the 'me_message' operation actually does. It only mentions routing through connector authority, leaving the tool's function ambiguous. The name hints at sending a message to oneself, but the description provides no confirmation.

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

Usage Guidelines1/5

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

No guidance is given on when to use this tool compared to the many sibling Slack tools like slack_post_message or slack_open_dm. The description is generic and does not differentiate this wrapper from alternatives. There is no indication of prerequisites or recommended invocation patterns.

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