Paginated list of active markets

problee_list_markets

Read-onlyIdempotent

List prediction markets on Kellian. Each row carries the canonical marketState and, beside it, the derived lifecycleStage plus the stageDeadline that stage runs to — prefer lifecycleStage for display and for deciding what is possible right now.

Examples: List live CRYPTO markets on Base

Input Schema

TableJSON Schema

Name	Required	Description	Default
`sort`	No	Sort order. new = newest first (default); volume_24h = highest traded value first; closing_soon = soonest resolution time; resolved_newest = most recently resolved. The keyset `cursor` only applies to `new`.	new
`cursor`	No	Keyset cursor from a prior response nextCursor.
`search`	No	Free-text search over the market question.
`chainId`	No
`creator`	No	Filter to markets whose on-chain creator wallet matches this address.
`category`	No
`pageSize`	No
`marketState`	No	Exact canonical market-state filter.
`pricingModel`	No	Filter by pricing engine: 'ORDERBOOK' = central limit order book markets; 'automated' = automated-market-maker markets.
`sourceTokenId`	No	Source outcome token ID, in decimal as the source market's orders name it: lists the market that follows it, each row carrying `sourceToken.side`, the order side that is that outcome.
`sourceConditionId`	No	Source market condition ID: lists the markets whose `resolutionSource` is `{type: 'polymarket', conditionId}` with this ID.

TDQS

A3.7/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld), so the bar is lower. The description goes beyond them by explaining the relationship between the returned `marketState`, derived `lifecycleStage`, and `stageDeadline`, and by telling the agent which field to prefer — genuine behavioral guidance. It omits pagination/auth/rate-limit behavior, so not a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short blocks with the purpose front-loaded and a concrete example appended. Every sentence earns its place, though the em-dash field-preference sentence is slightly dense and could be split.

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 no explanation, and the description still adds useful field-interpretation guidance. With 11 optional filters, it says nothing about how filters combine or about the cursor-only-applies-to-`new` pagination caveat (schema-only), which keeps it short of a 5.

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 description coverage is 73%; most filters (sort, cursor, search, creator, pricingModel, sourceTokenId/ConditionId) are richly documented in the schema itself, while chainId, category, and pageSize carry none. The description adds no parameter-level meaning beyond the schema, so the adequate-but-minimal baseline applies.

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 ('List prediction markets on Kellian') and the title confirms pagination. It does not distinguish itself from siblings like problee_list_pending_resolution_markets or problee_list_related_markets, but the general-purpose listing role is unambiguous.

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?

The single example ('List live CRYPTO markets on Base') implies when the tool is useful, and the hint to prefer lifecycleStage for 'deciding what is possible right now' implies an intent. There is no explicit when-not guidance or named alternative such as problee_get_market for a single market.

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