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.

TDQS

A4.9/5.0
Behavior5/5

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

Discloses detailed behavior beyond annotations: scanning logic, semantic anchor (Jaccard similarity, skipped pairs), partition filter (placeholder fraction), fill check with book depth analysis, and references to sibling tools for sizing. No contradictions 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?

Descriptive and well-organized with clear sections, but somewhat lengthy. Every sentence adds value, though slight verbosity in technical details could be tightened without losing clarity.

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?

Comprehensive coverage for a complex tool with no output schema: explains response fields (opportunities[], partition_check), fill check logic, and edge cases (deviations >3pp, placeholder filtering, realizable edge). No missing context.

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?

Adds extensive meaning beyond schema descriptions: explains each parameter's mode, gives example values, describes internal behavior (e.g., walk child markets, compute partition_check), and clarifies outputs and conditions.

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 clearly states the tool finds arbitrage opportunities via monotonicity violations and partition-sum checks on Polymarket, distinguishing it from sibling tools like polymarket_fill_risk by mentioning its integration and comparison.

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 explains three modes (no args, event, topic) with examples and when to use each, including recommendations (e.g., 'event recommended for a specific market') and warnings about when not to trade based on fill check results.

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

Many tools have overlapping purposes, especially in the prediction market domain (e.g., bet_research, polymarket_edges, polymarket_arbitrage, polymarket_fill_risk) and data querying (ask_pipeworx, ask_pipeworx_grounded, deep_research). This overlap creates confusion for an agent selecting the right tool.

Naming Consistency2/5

Naming is inconsistent: most tools use snake_case but some start with a verb (ask_, bet_, compare_) while others start with a noun (entity_profile, pipeworx_feedback, polymarket_*). There is no uniform pattern, making it harder to predict tool names.

Tool Count2/5

With 32 tools, the server is overstuffed for a single focus. It bundles checksums, AI visibility, data queries, prediction market analysis, subscriptions, memory, and more, which would be better split into separate, more focused servers.

Completeness2/5

Despite the large tool count, the server lacks completeness in key areas: no tool to place prediction market trades, no direct SEC filing detail extraction (only through generic queries), and only two checksum tools despite the server name 'Crc'. The surface feels scattershot rather than comprehensive.
