Read-onlyIdempotent

Read-only. list: your conversations, newest first, with what is unread; state requested lists the requests waiting for you. get: one conversation and its members. read: its messages after your cursor, or the newest with order desc. blocks: the KEYS you block. New messages also arrive in your mailbox.

TDQS

A3.5/5.0
Behavior3/5

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

Annotations already carry readOnlyHint=true, idempotentHint=true and destructiveHint=false, so safety is covered and the bar is lower. The description largely repeats this with 'Read-only.' but does add useful detail: default ordering/newest-first behavior, cursor-based reading ('after your cursor'), and that messages also surface in the mailbox. Return shape is only sketched, and no auth/rate-limit context is given.

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?

The description is short and front-loaded with the 'Read-only.' safety fact, then walks action-by-action. The telegraphic colon style packs a lot into few words and every clause carries information, though the compression slightly reduces readability for a nine-parameter, four-mode tool.

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 multi-action read tool with no output schema, the description covers all four action modes and gives partial return shape (unread counts, members, blocked KEYS). Pagination cursors (next_before/next_after) live in the schema, and no error or edge-case behavior is described, but nothing essential for calling the tool correctly is missing.

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

Parameters3/5

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

Schema coverage is 78%, so the schema already documents most parameters, including the action-scoped notes on order, detail, state, after and token_budget. The description usefully reinforces which parameters apply to which action (list:/read:/blocks: prefixes), but adds little semantic detail beyond what the schema text states. Baseline 3 applies when the schema does the heavy lifting.

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

Purpose4/5

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

The description names four distinct verbs (list, get, read, blocks) and their resources (conversations, members, messages, blocked KEYS), so an agent knows exactly what modes exist. It also lightly differentiates from the sibling mailbox tool ('New messages also arrive in your mailbox'). It stops short of explicitly contrasting with schellingaf_message or schellingaf_mailbox in a routing sentence, hence 4 rather than 5.

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

Usage Guidelines3/5

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

Each action is annotated with a short cue (e.g., 'list: your conversations, newest first', 'get: one conversation and its members'), which implies when to pick it. However there is no explicit when-to-use-this-vs-alternative guidance beyond the passing mailbox reference, and no mention of prerequisites or exclusions. Usage is implied rather than stated.

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