A4.1/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so safety is covered. The description adds genuinely useful context beyond them: keyless operation against any public instance, that data is live, and a concrete $0.05 per call cost — none of which appear in the structured fields.

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?

Front-loaded with the resource, then modes, then usage, then inputs and cost — a sensible ordering with no filler sentences. It is dense, and the trailing enumeration of return fields is somewhat list-heavy, but nothing is wasted.

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-mode, 9-parameter read tool this covers what an agent needs: the modes, their parameters, keyless access, live data and cost. Since an output schema exists, the return-field listing is largely redundant, which is the only real gap in an otherwise complete definition.

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 description coverage is 100%, so every parameter is already documented with its mode and limits. The description restates the mode list and the tag/acct/query pairing but adds no syntax, default or edge-case detail beyond what the schema provides — baseline 3 is appropriate.

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 resource (Mastodon data) with the four concrete modes it covers (hashtag timeline, account, search, trends) and the per-post payload. An agent can distinguish this from hubvibe_social_bluesky and hubvibe_social_x_pulse by the fediverse/Mastodon scoping alone.

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 a clear use case ('social listening and trend tracking in the fediverse') and enumerates the modes with their required inputs. However, it never names the sibling social tools as alternatives, so routing between Mastodon, Bluesky and X remains inferential.

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