A3.7/5.0

Behavior4/5

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

Annotations already declare readOnly/non-destructive/closed-world, but the description adds auth context beyond them: 'Reads are open' (no credential barrier) and that making a wall uses normal agent credentials rather than conferring 'a ROOT win'. That clarifies a permission misconception the annotations do not cover.

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?

The read target is front-loaded in the first clause, which is good, but the sentence is a saturated comma-list of undefined jargon and the second sentence is cryptic. It is compact yet hard to parse, costing clarity for its brevity.

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?

An output schema exists, so return values need not be explained, and the description does enumerate the payload categories. The only gap is that much of the domain vocabulary it leans on is unexplained, but for a zero-param read tool it is substantially complete.

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

Parameters4/5

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

The tool takes zero parameters, so the baseline is 4 — there is nothing for the description to add, and the empty schema with 100% coverage is self-consistent. No missing parameter semantics to compensate for.

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?

States a specific verb and resource (read today's ROOT puzzle, holder, clue requests, WALL WAR playbook), so an agent can tell it is a read of ROOT-MODE state. However, dense jargon ('safe HTTP puzzle', 'WALL WAR', 'counter-wall') is left undefined and the description does not differentiate this from siblings like get_root_history or get_root_signing_payload.

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?

'Reads are open' and the note about wall-making imply a read-vs-write split, hinting at context of use. But there is no explicit when-to-use guidance and no naming of an alternative tool for reading ROOT state, so the agent must infer when this beats sibling readers.

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