  2. First observedv2.0.0

TDQS

C2.9/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the mutation profile is covered. The description adds genuinely new context: the confirm=true gate, the fact that it changes account state, and the OAuth scope requirement (posts:write). It is consistent with, not contradicted by, the annotations.

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

Conciseness3/5

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

Three short sentences, front-loaded with constraints, so there is no padding. However, the opening sentence "Update post." earns nothing and could have been spent on scope detail, making the brevity partly under-specification rather than tightness.

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

Completeness3/5

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

For a high-complexity destructive mutation with no output schema and 31 parameters, the description covers the safety-critical bits (confirm, auth scope) but is silent on the tool's actual scope, the blocks-vs-body_content exclusivity, and the payload variants. The rich schema compensates for much of the parameter detail, keeping this at a minimum-viable level.

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

Parameters2/5

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

Schema coverage is 65%, so a meaningful share of the 31 parameters are undocumented. The description only touches confirm, and its phrasing duplicates the schema's own confirm description ("Set true only when the user asked for exactly this action"). It adds no syntax, format, or constraint detail for title, blocks, status, payload, or the other body flags.

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

Purpose3/5

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

"Update post" names a specific verb+resource and distinguishes it from create_post/delete_post/get_post, but the sentence is essentially a restatement of the name and says nothing about what aspects of a post can be updated. For a tool with a 31-parameter surface, this is vague rather than specific.

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

Usage Guidelines2/5

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

The description gives a conditional rule (confirm=true for the user-requested action) but no guidance on when to use update_post versus siblings like create_post, delete_post, or the payload/payload_file variants. No when-not conditions or alternative routing are offered.

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