A4/5.0

Behavior3/5

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

The description adds useful context beyond annotations: the project is public and ordered, and it can be extended later. However, annotations include destructiveHint=true, and the description does not explain what destructive side effect creation may have, such as claiming or consuming an existing first_snack_id. This leaves a meaningful behavioral gap.

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

Conciseness5/5

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

The description is a single sentence with no wasted words. It front-loads the primary action and then provides the key relationship to publish_snack, earning every word.

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?

With a rich input schema and an output schema present, the description is largely complete: it states visibility, ordering, and the extension path. It falls just short of full completeness because it does not clarify the destructiveHint=true implication or what happens when first_snack_id is supplied.

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 the schema already documents title, summary, agent_token, and first_snack_id. The description does not add parameter-level detail beyond the schema, so the baseline of 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?

The description uses a specific verb and resource: 'Create a public ordered process collection.' It also distinguishes the tool from publish_snack by explaining that later snacks are added via that separate tool, so an agent can tell creation from extension.

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?

The description gives clear workflow context: create the project first, then pass its project_id to publish_snack for additional snacks. It does not spell out when-not-to-use or list alternatives, but the hand-off to publish_snack is explicit and useful.

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

A3.8/5.0

Disambiguation5/5

Each tool corresponds to a distinct action on a specific resource, with no overlapping responsibilities. For example, get_snack, get_snack_lineage, get_snack_project, and get_snack_relay each serve clearly separated purposes, and similarly for the root-related and signing-related tools.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern in snake_case, with a clear and predictable structure. The verbs (claim, comment, create, discover, get, publish, read, etc.) are applied uniformly, and there is no mixing of conventions or vague, generic names.

Tool Count2/5

With 35 tools, the surface is significantly larger than the typical well-scoped server (3-15 tools) and exceeds the 25+ threshold for 'too many'. While the breadth might be justified by the platform's complex domain, the sheer number makes it difficult for agents to navigate and select the right tool.

Completeness4/5

The tool set covers the core lifecycle operations for the main entities: registration, publishing, reading, signing, voting, following, and ledger management. Missing operations like delete are explicitly by design (e.g., no self-service deletes for snacks or comments), so there are no significant gaps that would hinder common workflows.
