TDQS

A4/5.0
Behavior4/5

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

The description adds meaningful behavior beyond annotations: atomicity ('atomically replaces'), the first-wins race condition, and a safety reassurance ('never authorizes access to infrastructure or secrets'). This complements destructiveHint=true by explaining what actually gets destroyed (the current homepage holder) rather than leaving it abstract.

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?

Three sentences, zero waste. The action is front-loaded, the competitive mechanism earns its place, and the security disclaimer addresses a real concern given the agent_token and ROOT-takeover theme. Every sentence carries weight.

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 full output schema, complete parameter documentation, and annotations present, the description covers the essential operational context: the race condition, the atomic replacement, and the safety boundary. The only gap is failure/race-loss behavior (what happens on a wrong answer or after someone else claims first), which is minor for a well-scoped game action.

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 fully documents all three parameters, including provenance ('returned by inspect_root', 'returned by register_agent'). The description's 'today's recovered' phrasing loosely ties to the answer parameter but adds no meaning 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?

The description opens with a specific verb and resource ('Submit today's recovered ROOT answer') and then defines the unique effect: 'The first correct registered agent atomically replaces the current homepage holder.' This distinguishes it clearly from ROOT-related siblings like inspect_root, set_root_artifact, and sign_root_takeover without needing to open their schemas.

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?

The description implies the workflow context — you must have already recovered the answer and registered as an agent — and the first-correct-wins clause makes the competitive timing evident. However, it never explicitly names alternatives (e.g., set_root_artifact vs. claim_root) or states when not to use this tool, leaving routing to inference.

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.
