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.

A4.5/5.0
Behavior4/5

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

Annotations cover read-only, idempotent, destructive hints, and the description adds behavioral context: key-value scoping by identifier, persistence differences between authenticated and anonymous users (24-hour retention), and session-crossing capability. It does not contradict annotations, though it could detail overwrite behavior, which is implied by idempotentHint.

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 four sentences, each serving a distinct purpose: main action, usage context, storage/retention details, and pairing with related tools. It is front-loaded with the core purpose and contains no filler.

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 tool with no output schema, the description covers all essential aspects: what, when, how (key-value), scoping, persistence, and complementary tools. It provides sufficient context for an agent to use it correctly without any gaps.

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%, so baseline is 3. The description mentions key-value pair but does not add significant parameter-specific meaning beyond the schema's examples and descriptions. It reinforces that 'value' is free text, matching the schema.

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 saves data for later reuse with specific verb 'Save' and resource 'data'. It distinguishes from siblings by explicitly pairing with recall for retrieval and forget for deletion.

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 provides explicit when-to-use guidance: 'Use when you discover something worth carrying forward' with concrete examples. It names alternatives (recall, forget) and explains the pairing, making it clear when to use this tool vs others.

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

A4/5.0
Disambiguation3/5

Descriptions are unusually explicit about when to use each tool (single lookup vs grounded vs deep research), but the set still contains several genuinely overlapping tools: ask_pipeworx_beta is explicitly identical to ask_pipeworx, scan_competitor_ai_presence wraps ai_visibility, and six polymarket_* tools share the same 'edge/arbitrage' conceptual space. An agent can usually pick the right tool but faces real ambiguity in several clusters.

Naming Consistency4/5

Names are uniformly snake_case and readable, and there are coherent prefix families (ask_pipeworx_*, polymarket_*, pipeworx_*). However the verb placement is inconsistent: verb_noun (ask_pipeworx, validate_claim, discover_tools) coexists with noun-first names (recent_changes, entity_compare, layer_info, polymarket_edges), and bet_research sits outside the polymarket_* family despite being a prediction-market tool.

Tool Count2/5

34 tools is well past the 'feels heavy' threshold, and more importantly the set mixes what looks like three different servers: a tiny ArcGIS/Longview GIS slice (layer_info, query_layer, search_datasets), a massive general-purpose data-research platform from Pipeworx, and a Polymarket prediction-market toolkit. Most tools earn their place for the platform, but far too few belong to the named domain.

Completeness4/5

The research surface is remarkably complete: a router, grounded and beta variants, deep multi-source research, claim verification, entity/profile/change resolution, discovery and suggestion helpers, memory (remember/recall/forget), subscriptions (subscribe/unsubscribe/recent_alerts), and feedback — no obvious lifecycle dead ends. Minute gaps exist on the GIS side (no dataset editing, no metadata browsing, no named export/view ops) and a few nooks like screen- leisure tools have no progress/status endpoints, but these are workaroundable.
