Read-onlyIdempotent

Machine-readable manifest of this server: available tools, knowledge domains, current kb_snapshot, determinism guarantees, and limits. Call this first to self-configure.

A4.4/5.0

Behavior4/5

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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds useful context beyond annotations, such as returning current kb_snapshot, determinism guarantees, and limits, and positions the tool as a self-configuration mechanism. It does not detail output format, but the risk profile is low and well-covered.

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 a scannable colon-delimited content list and a direct action instruction. Every word contributes value; there is no redundancy or filler.

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 simple zero-argument manifest endpoint, the description sufficiently covers purpose, content categories, and invocation order. The phrase 'machine-readable manifest' hints at the return format, and given the tool's simplicity, the description is adequately 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 has zero parameters and an empty input schema, so the baseline of 4 applies. The description correctly omits parameter details because there is nothing to document; no additional semantic burden exists.

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 clearly identifies the tool as a 'machine-readable manifest of this server' and enumerates its contents (available tools, knowledge domains, kb_snapshot, determinism guarantees, limits). It is immediately distinguishable from operational siblings like search or browse by framing itself as an entry-point/self-configuration resource.

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 provides explicit timing guidance: 'Call this first to self-configure.' This clearly implies invocation before other tools. It does not name alternatives or exclusions, but the entry-point role is clear enough for a zero-parameter discovery tool.

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