Polymarket Arbitrage

polymarket_arbitrage
Read-onlyIdempotent

Find arbitrage opportunities on Polymarket via monotonicity violations + partition-sum checks. Call with NO args for a trending_scan of the top ~200 markets by weekly volume; pass event for the strongest per-event partition_check, or topic for a themed cross-event scan. event (recommended for a specific market): pass a Polymarket event slug like "fed-decision-may-2026" or "when-will-bitcoin-hit-150k"; walks child markets, checks date-axis / threshold-axis ordering AND computes the partition_check (sum of YES prices across mutually-exclusive legs — should ≈1; deviations >3pp emit a BUY/SELL EVERY LEG signal). topic (for cross-event scanning): pass a seed question like "Strait of Hormuz traffic returns to normal" or "Fed rate decision"; searches related events across the platform, flattens markets, runs the comparator on the union. Cross-event mode catches "...by May 31" vs "...by Jun 30" patterns that single-event misses. SEMANTIC ANCHOR: cross-event pairs require ≥0.30 Jaccard similarity on question tokens (prevents Powell-Fed-Pause being paired with Powell-DOJ-probe); skipped_low_similarity surfaces the rejected pair count. PARTITION FILTER: drops will-person-X / will-manager-Y / will-someone-else- placeholder slugs; partitions with >20% placeholder fraction return null arb signal. Response: opportunities[] (gap_pp, suggested_trade, reasoning, monotonicity violation context), and in event mode partition_check{sum_yes_prices, gap_from_1, placeholders_filtered, suggested_trade}. FILL CHECK: when the partition signal fires, arbitrage.fill_check prices it against live CLOB depth (theoretical_edge_pp_at_book vs realizable_edge_pp at 1000 shares/leg, thin_legs[]) — realizable_edge_pp ≤ 0 means the overround exists only at last-trade, not in the book; do not trade it. For custom sizing use polymarket_fill_risk.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
eventNoSingle-event mode (use this if you know the specific Polymarket event): event slug like "fed-decision-may-2026" or "when-will-bitcoin-hit-150k". Full Polymarket URLs also accepted.
topicNoCross-event mode (use this if you want to scan related events across the platform): a topic or seed question like "Fed rate decision" or "Strait of Hormuz traffic returns to normal". Tool searches Polymarket for related events and checks monotonicity across them.

A4.6/5.0
Behavior5/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true, but the description adds substantial behavioral context: Jaccard similarity threshold (≥0.30), placeholder-slug filtering, partition-check deviation threshold (>3pp), and the fill-check pricing process (theoretical vs realizable edge at 1000 shares/leg). It even warns not to trade when realizable_edge_pp ≤ 0. This goes well beyond the structured 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 long but densely packed with valuable directives, examples, and caveats. It is front-loaded with the primary purpose and uses capitalized section headers (SEMANTIC ANCHOR, PARTITION FILTER, FILL CHECK) to aid scanning. A few sentences could be trimmed, but nothing feels extraneous.

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?

The tool has no output schema, but the description compensates by specifying the response shape: opportunities[] with fields like gap_pp, suggested_trade, reasoning, and partition_check details. It covers edge cases (placeholder filters, low-similarity skips, fill-check overround) and points to polymarket_fill_risk for sizing, making the tool fully usable with the information provided.

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?

The input schema already provides full descriptions and 100% coverage for both parameters. The description adds extra meaning with concrete slug examples, URL acceptance, mode recommendations ('recommended for a specific market'), and behavior details like 'walks child markets' and 'searches related events', making the parameters more actionable than the schema alone.

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 opens with a specific action ('Find arbitrage opportunities on Polymarket') and the method ('monotonicity violations + partition-sum checks'), clearly distinguishing it from generic search or monitoring tools. It also contrasts with sibling polymarket_fill_risk by mentioning custom sizing, reinforcing its role as the arbitrage-detection tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit when-to-use guidance for each parameter mode: 'event (recommended for a specific market)' and 'topic (for cross-event scanning)', with examples and trade-offs like 'Cross-event mode catches patterns that single-event misses.' It also points to polymarket_fill_risk for custom sizing, though it does not explicitly discuss alternatives like polymarket_edges or polymarket_edge_tracker.

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

B3.3/5.0
Disambiguation2/5

The tools span vastly different domains (AI visibility, data querying, prediction markets, GIS) with clear descriptions individually, but the set lacks a coherent focus. An agent looking for ArcGIS functionality would be distracted by many unrelated tools, causing confusion in tool selection.

Naming Consistency2/5

Most tool names use snake_case, but there is no consistent verb_noun pattern. Some names are verbs (remember, forget), others are noun phrases (entity_profile, layer_info), and some include underscores inconsistently (generate_llms_txt vs. bet_research). The naming feels arbitrary.

Tool Count1/5

With 33 tools, the count is high, but the vast majority are from Pipeworx and unrelated to the server's stated purpose (Arcgis Roanoke). Only 3-4 tools actually relate to GIS. The tool count is extremely inappropriate for the server's focus.

Completeness1/5

For the implied domain of ArcGIS Roanoke, the tool surface is severely incomplete, lacking CRUD for map layers, spatial queries, or data management. Conversely, the Pipeworx subset is also incomplete on its own (e.g., missing many data sources). The overall surface fails to serve any single domain well.
