Idempotent

Save data the agent will need to reuse later — across this conversation or across sessions. Use when you discover something worth carrying forward (a resolved ticker, a target address, a user preference, a research subject) so you don't have to look it up again. Stored as a key-value pair scoped by your identifier. Authenticated users get persistent memory; anonymous sessions retain memory for 24 hours. Pair with recall to retrieve later, forget to delete.

A4.9/5.0
Behavior5/5

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

Beyond annotations, the description discloses scoping ('scoped by your identifier') and persistence differences ('Authenticated users get persistent memory; anonymous sessions retain memory for 24 hours'). It also explains the write nature and storage format, adding significant value beyond the readOnlyHint/idempotentHint annotations. No contradiction found.

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 five well-structured sentences, each serving a purpose: main action, usage guidance, storage mechanism, persistence behavior, and companion tools. It is front-loaded with the primary function and wastes no words.

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?

For a simple write operation with two parameters and no output schema, the description fully covers purpose, usage, storage semantics, persistence, and tool integration. The annotations already address safety (non-destructive, idempotent), so the description is complete enough for an agent to select and invoke correctly.

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 schema already has clear descriptions for both parameters with examples. The description adds extra semantic value by mentioning key-value scoping by identifier, and provides additional examples of keys/values (resolved ticker, target address). This goes slightly beyond the schema's coverage, so a 4 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 begins with a specific verb and resource: 'Save data the agent will need to reuse later.' It clearly distinguishes itself from siblings by mentioning complementary tools (recall, forget) and explains the key-value storage model. The purpose is unambiguous and covers cross-session persistence.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly states when to use: 'Use when you discover something worth carrying forward...' and provides concrete examples. It also ties to alternatives by saying 'Pair with recall to retrieve later, forget to delete,' giving clear usage context and tool relationships.

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
Disambiguation4/5

Descriptions are exceptionally detailed and differentiate tools well; the ask_pipeworx family (stable/beta/grounded), polymarket tools, and npm lookup tools each have clear separation of intent. Minor overlap exists between polymarket_edges and polymarket_arbitrage (both surface opportunities) and between discover_tools, suggest_questions, and pipeworx_trending (all aid discovery), but descriptions mostly resolve the ambiguity.

Naming Consistency3/5

All names are snake_case and several families are consistent (get_*, list_*, search_*, ask_pipeworx, polymarket_*), but the convention is inconsistent: verb-first names (resolve_entity, validate_claim, scan_dependency) coexist with noun-first or noun-only names (entity_profile, deep_research, bet_research, recent_alerts, ai_visibility_check, pipeworx_trending, polymarket_arbitrage). No clear governing pattern beyond snake_case.

Tool Count2/5

36 tools is well over the 25-tool heavy threshold, and the majority (~29) are unrelated to the server's declared 'npm' identity — they are Pipeworx data-query, prediction-market, memory, and subscription tools. Only about 7 tools (search_packages, get_package, get_version_info, list_versions, get_downloads, scan_dependency, generate_llms_txt) actually pertain to npm. The scope is a kitchen-sink mismatch with the server name.

Completeness3/5

For npm, the read-side surface is reasonably complete: search, inspect package metadata, version listings, download counts, and a dependency-safety composite check. However, there are no lifecycle operations (publish, unpublish, deprecate, set versions/tags), leaving a notable gap, and the bulk of the server's functionality (data queries, prediction bets) belongs to an entirely different domain that can't be cohesively evaluated against the npm purpose.
