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.

TDQS

A4.9/5.0
Behavior5/5

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

Annotations already indicate safe read-only, idempotent behavior. Description adds that it checks live order-book depth, returns a verdict (clean|degraded|cannot_fill), and reveals the critical risk of partial fills converting arbs to directional positions—value beyond what annotations provide.

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?

Description is long but well-structured with headings (SINGLE-MARKET, BASKET) and clear sections for parameters and returns. Every sentence adds value, though slightly more concise phrasing could be possible. Front-loaded with the core purpose.

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?

Despite no output schema, the description thoroughly explains return fields for both modes (top_of_book, vwap_fill_price, slippage, verdict, etc.) and covers edge cases like thin_legs and forced_directional_risk. Agents have sufficient information to understand tool behavior and consequences.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but description adds meaning: default values for 'side' (auto in basket), interpretation of 'size_usd' as settlement notional in basket mode, clamp range 10–1,000,000, and specifies that 'market' and 'event' are mutually exclusive but one is required. Adds significant semantic context.

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?

Clearly states it performs a realizable-vs-theoretical edge check against live order-book depth, distinguishes single-market and basket modes, and provides verdicts. Explicitly contrasts with sibling tools by stating when to use this tool before acting on arb signals.

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?

Explicitly says 'USE THIS before acting on any polymarket_arbitrage SELL/BUY-EVERY-LEG signal or any polymarket_edges trade above ~$500', providing clear when-to-use context and implicit when-not-to-use. Also warns about partial fills converting to directional positions, guiding appropriate invocation.

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
Disambiguation2/5

ask_pipeworx and ask_pipeworx_beta are explicitly described as functionally identical right now, making them near-duplicates. ai_visibility_check and scan_competitor_ai_presence also heavily overlap, and deep_research vs ask_pipeworx requires careful reading to know which to pick.

Naming Consistency4/5

Most tools follow a clear snake_case verb_noun pattern (list_templates, create_*, validate_claim). However, a few bare verbs break the pattern: compose, forget, recall, and remember.

Tool Count1/5

34 tools is already heavy, but the server is named 'Gitignore' and only 3 of 34 tools relate to .gitignore templates. The other 31 tools form a completely unrelated data platform, making the count an extreme mismatch for the apparent scope.

Completeness3/5

As a data platform, the surface is broad but has notable gaps: citations return pipeworx:// URIs yet no fetch/read-by-URI tool exists, and subscriptions support subscribe/unsubscribe/list but not update. For the gitignore name, only basic template list/get/compose is present, with the rest irrelevant to the stated purpose.
