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.

A5/5.0
Behavior5/5

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

Even with annotations declaring readOnly/idempotent/non-destructive, the description adds substantial behavioral detail: how partition_check sums YES prices, the >3pp threshold for emitting a signal, placeholder-slug filtering, Jaccard similarity anchors, and the fill-check caveat that a positive theoretical edge does not guarantee a realizable edge in the book. It openly warns 'do not trade it' when realizable_edge_pp ≤ 0.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Although long, the description is densely informative with clear section labels (SEMANTIC ANCHOR, PARTITION FILTER, FILL CHECK) and front-loads the core purpose in the first sentence. Every section adds operational nuance without redundant phrasing, earning its place.

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 the tool's complexity, no output schema, and zero required parameters, the description fully compensates by specifying the response shape (opportunities[], partition_check fields), mode-specific outputs, and the fill-check pricing behavior. It leaves no major behavioral gap for an agent to guess.

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 the description adds examples for both parameters ('fed-decision-may-2026' for event, 'Strait of Hormuz traffic returns to normal' for topic) and clarifies mode-specific behavior. It explains what happens with no args and characterizes event as 'recommended' for specific markets, going well beyond the schema's property descriptions.

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 clear verb+resource: 'Find arbitrage opportunities on Polymarket via monotonicity violations + partition-sum checks.' It distinguishes three distinct modes (trending_scan, event, topic) and differentiates from sibling tools like polymarket_edges and polymarket_fill_risk by explicitly positioning arb detection versus fill-risk pricing.

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?

It explicitly states when to call with no args ('trending_scan'), when to use 'event' ('recommended for a specific market'), and when to use 'topic' ('for cross-event scanning'). It also names an alternative tool ('For custom sizing use polymarket_fill_risk') and explains that cross-event mode catches patterns single-event misses.

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

A3.7/5.0
Disambiguation3/5

Most tools are distinctly named and the descriptions are unusually specific, but the set contains overlapping families: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, and deep_research all route to the same underlying data, and the beta variant is currently an exact duplicate. The entity/company lookup, AI-visibility, and Polymarket clusters also require reading the long descriptions to choose correctly.

Naming Consistency3/5

All names are lowercase snake_case and readable, with useful prefixes like ask_pipeworx, polymarket_, and pipeworx_. However the macro pattern is mixed: many are verb-first (compare_entities, resolve_entity), many are noun phrases (entity_profile, polymarket_edge_tracker, recent_alerts), and one puts the verb last (linkedin_humblebrag_generate).

Tool Count2/5

32 tools is far too many for a server whose apparent name and stated LinkedIn-humblebrag purpose are served by exactly one tool. Even viewed as a general Pipeworx/research utility, the surface is bloated: duplicate ask variants, multiple meta-tools, and a sprawling prediction-market family push the count well past the 25-tool threshold.

Completeness2/5

For the domain implied by the server name, the surface is severely incomplete: only generation exists, with no way to list, edit, delete, publish, or manage LinkedIn-humblebrag posts. The de facto Pipeworx research domain is much better covered, but the overall set has serious dead ends because the one LinkedIn tool is isolated and the core tools are oriented toward a different, unrelated workflow.
