Read-onlyIdempotent

Retrieve a value previously saved via remember, or list all saved keys (omit the key argument). Use to look up context the agent stored earlier — the user's target ticker, an address, prior research notes — without re-deriving it from scratch. Scoped to your identifier (anonymous IP, BYO key hash, or account ID). Pair with remember to save, forget to delete.

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds context about scoping (anonymous IP, BYO key hash, or account ID) and mentions pairing with remember/forget, which provides additional behavioral insight beyond the annotations.

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, front-loaded with core function, no unnecessary words. Every sentence adds value: purpose, usage examples, and pairing with other tools.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given one optional parameter, no output schema, and rich annotations, the description covers all necessary context: what the tool does, when to use it, and how it relates to sibling tools. It is complete for its complexity.

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 coverage is 100% with a single optional parameter 'key' described. The description adds that omitting the key lists all keys, but this is already evident from the schema's optional nature. No additional parameter semantics are provided beyond what the schema offers.

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 states the tool's purpose: 'Retrieve a value previously saved via remember, or list all saved keys (omit the key argument).' It specifies the verb and resource, and distinguishes itself from siblings like remember and forget.

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 concrete usage scenarios: 'Use to look up context the agent stored earlier — the user's target ticker, an address, prior research notes — without re-deriving it from scratch.' It also notes scoping and pairing with other tools, but lacks explicit when-not-to-use guidance.

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

A3.6/5.0
Disambiguation2/5

The tool set mixes tools from multiple unrelated domains (HathiTrust, Pipeworx data platform, Polymarket, npm, etc.), making it unclear which tool to use for a given task. Overlap exists between ask_pipeworx and ask_pipeworx_grounded, and between several Polymarket tools, while the HathiTrust-specific tools are few and buried among many others, causing confusion.

Naming Consistency2/5

Naming conventions are inconsistent across the tool set. Some tools use verb_noun (check_full_view, lookup_by_identifier), others use noun_verb (entity_profile, deep_research), and some are single verbs (forget, remember, subscribe). There is no predictable pattern, making it harder for an agent to guess tool names.

Tool Count1/5

With 33 tools, the count is high, but only 3 (get_record, lookup_by_identifier, check_full_view) are relevant to the server's stated purpose (HathiTrust). The remaining 30 tools appear to be from unrelated domains (Pipeworx data platform, Polymarket, npm, etc.), making the tool count severely mismatched with the server name.

Completeness2/5

For the HathiTrust domain, the tool surface is severely incomplete: only three basic lookup tools with no search, browse, or management capabilities. The broader set includes tools for many other domains, but that does not compensate for the lack of coverage of the server's primary purpose.
