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.

A4.8/5.0
Behavior5/5

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

Adds detailed behavioral context beyond annotations: walks order book ladder, returns specific fields (top_of_book, vwap, slippage, verdict, etc.), and explains risks like thin legs and forced directional risk. No contradiction with readOnlyHint, destructiveHint, idempotentHint.

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 substantial but well-organized with sections and bullet-like lists. Every sentence adds value, though it could be slightly more concise. Front-loaded with 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?

Given no output schema, the description fully explains return values for both modes, including edge cases like thin legs and partial fills. Covers all necessary context for an agent to use the tool 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?

Schema has 100% coverage, but description enhances understanding by explaining parameter roles in different modes, defaults, and interactions (e.g., side default logic, size_usd interpretation). Adds moderate value over 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?

Clearly defines the tool as a realizable-vs-theoretical edge check against live order-book depth, with explicit single-market and basket modes. Distinguishes itself from siblings by stating use before polymarket_arbitrage signals or large trades.

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 states when to use: before acting on polymarket_arbitrage signals or trades above ~$500. Warns about partial basket fills converting arb to unhedged position, providing clear context for usage.

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

A3.5/5.0
Disambiguation2/5

The set has several near-duplicate tools: ask_pipeworx and ask_pipeworx_beta are explicitly designed to be identical right now, and ask_pipeworx_grounded, deep_research, and bet_research all overlap on routed data lookup. The three Reddit tools are distinct, but they are dwarfed by a large cluster of unrelated Pipeworx/Polymarket tools, making the actual purpose of the set hard to pin down.

Naming Consistency2/5

Naming conventions are wildly mixed: some tools use verb_noun (get_post, subscribe, suggest_questions), some use noun phrases (entity_profile, recent_alerts, pipeworx_trending), and some use ad-hoc names (ask_pipeworx, bet_research, scan_dependency). Within sub-families (polymarket_*, ask_pipeworx_*) names are consistent, but overall there is no single predictable pattern.

Tool Count1/5

34 tools is excessive for a server named 'Reddit' when only 3 of them (get_post, get_subreddit, search_posts) actually relate to Reddit. The remaining 31 tools cover unrelated domains like Pipeworx data routing, Polymarket betting, memory management, and npm dependency scanning—an extreme scope mismatch for the advertised server name.

Completeness1/5

The Reddit surface is severely incomplete: it offers read-only post/subreddit/search functionality with no create, edit, delete, vote, comment, or user-profile operations. Conversely, the Pipeworx tooling is over-complete relative to the 'Reddit' name, covering data lookups, prediction markets, subscriptions, and memory—none of which belong in a Reddit server.
