Polymarket Fill Risk

polymarket_fill_risk
Read-onlyIdempotent

Realizable-vs-theoretical edge check against live CLOB order-book depth. REQUIRES one of market (single-market mode) or event (basket/partition mode). SINGLE-MARKET: pass a market slug/URL + side (buy_yes|sell_yes|buy_no|sell_no, default buy_yes) + size_usd (default 1000 — max spend on buys, target proceeds on sells); walks the ladder and returns top_of_book, vwap_fill_price, slippage_pp, shares_filled, max_fillable_usd, and a verdict (clean|degraded|cannot_fill). BASKET: pass an event slug/URL + side (sell_yes = capture overround by selling every leg, buy_yes = capture underround; default auto from partition sum) + size_usd interpreted as settlement notional S (shares per leg; each share pays $1); returns theoretical_sum vs realizable_sum (top-of-book vs VWAP across all legs), capture_ratio, profit_usd at executed size, per-leg fill detail, thin_legs[], max_clean_notional_usd, and forced_directional_risk naming the legs most likely to strand you unhedged. USE THIS before acting on any polymarket_arbitrage SELL/BUY-EVERY-LEG signal or any polymarket_edges trade above ~$500 — theoretical overround on thin books is not capturable, and partial basket fills convert an arb into an unhedged directional position (the dominant loss mode in real arb-bot P&L).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sideNoSingle-market: buy_yes | sell_yes | buy_no | sell_no (default buy_yes). Basket: sell_yes | buy_yes (default auto — sell if partition sum > 1, buy if < 1).
eventNoBasket mode: event slug or full polymarket.com URL — checks every leg of the partition.
marketNoSingle-market mode: market slug or full polymarket.com URL.
size_usdNoSingle-market: USD to spend (buys) or target proceeds (sells). Basket: settlement notional — shares per leg, each paying $1 at resolution. Default 1000, clamp 10–1,000,000.

A4.7/5.0
Behavior5/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint (false). The description adds significant behavioral context: it explains how the tool walks the order book, returns a verdict (clean|degraded|cannot_fill), and warns about partial basket fills converting an arb into an unhedged directional position. No contradiction with annotations.

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?

The description is structured with clear sections for SINGLE-MARKET and BASKET modes, using bold labels. While it is somewhat verbose, every sentence adds necessary detail. It could be slightly more concise, but it remains well-organized.

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?

Given the tool's complexity (two modes, many return fields, no output schema), the description covers key return values (top_of_book, vwap_fill_price, slippage_pp, verdict, etc. for single-market; theoretical_sum, capture_ratio, thin_legs, etc. for basket). It also explains the risk of partial fills. However, it lacks details on error handling or invalid input behavior.

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?

Schema coverage is 100% with descriptions for each parameter, but the description adds value by clarifying mode-specific interpretations (e.g., size_usd meaning varies for single-market vs basket). It also explains default behaviors (e.g., side default auto in basket mode).

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 explicitly states the tool performs a 'realizable-vs-theoretical edge check against live CLOB order-book depth.' It distinguishes two modes (single-market and basket) and clearly differentiates from sibling tools like polymarket_arbitrage and polymarket_edges.

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?

The description provides explicit usage guidance: 'USE THIS before acting on any polymarket_arbitrage SELL/BUY-EVERY-LEG signal or any polymarket_edges trade above ~$500.' It explains why (theoretical overround on thin books is not capturable and partial fills create directional risk).

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

There are several near-duplicate clusters: ask_pipeworx, ask_pipeworx_beta (explicitly described as currently identical), ask_pipeworx_grounded, deep_research, and validate_claim all route to the same underlying data; the six Polymarket tools (bet_research, arbitrage, edges, edge_tracker, fill_risk, kalshi_spread) heavily overlap in purpose and are easy to confuse. Even detailed descriptions do not fully resolve which tool an agent should pick first.

Naming Consistency3/5

All names use snake_case and many follow a verb_noun pattern (search_filings, get_filing, list_issue_codes, resolve_entity), but there is a mix of verb-first names (ask_pipeworx, compare_entities, generate_llms_txt), noun-first names (recent_changes, entity_profile, pipeworx_trending), and brand-prefixed families (pipeworx_*, polymarket_*). The naming is readable but not a single predictable pattern.

Tool Count2/5

A server named 'Senate Lobbying' exposes 34 tools, but only three (search_filings, get_filing, list_issue_codes) relate to LDA lobbying data. The remaining 31 cover generic Pipeworx data lookup, prediction markets, memory, subscriptions, AI visibility, and npm package audits—an extreme overreach for the apparent scope and likely to confuse an agent expecting a focused lobbying toolkit.

Completeness2/5

For the lobbying domain implied by the server name, only search, get-one-filing, and issue-code enumeration exist; there is no aggregation/stats tool, no lobbyist/client entity resolution for LDA, no registrant or foreign-entity browsing, and no coverage of related concepts like lobbying firm hierarchies or spending trends. The generic Pipeworx tools fill a different domain, so the lobbying-specific surface has significant gaps.
