Polymarket Edge Tracker

polymarket_edge_tracker
Read-onlyIdempotent

Edge persistence and decay telemetry built from daily polymarket_edges snapshots. Answers "how long has this edge existed and is it shrinking?" — a fresh wide edge and a 3-week-old wide edge are different trades (the latter is wide for a reason nobody is willing to take). Args: days (lookback, default 14, max 30), window (snapshot family, default "1wk"). RESPONSE: tracked[] = every opportunity in the LATEST snapshot with its full edge_pp_net time-series across prior snapshots, first_seen, trend (new | widening | stable | decaying) and decay_pp_per_day (both computed on |edge_pp_net| — the value itself is signed by trade direction, negative = SELL YES); expired[] = opportunities that appeared in earlier snapshots but are GONE from the latest (closed, resolved, or arbed away) with their lifespan_days — the median lifespan is your competition clock; snapshot_dates[] = which days actually have data (snapshots are written when polymarket_edges runs on a cache-miss, so gaps mean nobody scanned that day). LIMITS: history depth is bounded by the 60-day snapshot TTL and starts from when snapshotting was enabled; decay numbers come from daily closes of edge_pp_net (net of default slippage), not intraday.

A4.6/5.0
Behavior5/5

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

Annotations already indicate readOnly, openWorld, idempotent, and non-destructive behavior. The description adds substantial context beyond these: snapshots are only written on cache-miss (gaps mean no scan), history is bounded by a 60-day TTL, and decay is computed from daily closes net of default slippage. This clearly explains temporal quirks and data semantics, going well beyond the annotation hints.

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 dense but well-organized with an opening summary, 'Args', 'RESPONSE', and 'LIMITS' sections. Every sentence contributes useful information, though the illustrative analogy about fresh vs. 3-week-old edges could be trimmed without losing core content. The length is justified given the complexity and lack of an output schema.

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?

With no output schema, the description thoroughly documents the response structure: tracked[], expired[], and snapshot_dates[], including field meanings like edge_pp_net sign convention and decay metrics. It also covers data gaps, TTL limits, and computation basis, making it complete enough for an agent to understand what results to expect and how to interpret them.

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 covers both parameters fully with defaults and clamps. The description adds meaning by explaining that 'window' selects the snapshot family (24hr | 1wk | 1mo) and 'days' controls lookback, reinforcing real-world significance. It does not introduce new schema fields but clarifies the role of parameters in the context of snapshotting behavior.

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's purpose: edge persistence and decay telemetry built from daily polymarket_edges snapshots. It explicitly names the core question it answers ('how long has this edge existed and is it shrinking?') and distinguishes it from sibling tools like polymarket_edges by focusing on time-series trends and lifecycle rather than current edge values.

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 provides clear context on when to use the tool: to analyze edge persistence over time and detect decay. It implicitly contrasts with fresh edge data via the example of a 3-week-old wide edge. However, it does not explicitly name alternative tools or state 'use X instead when,' so exclusions are only implied rather than direct.

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

Multiple tools have unclear boundaries: ask_pipeworx_beta currently behaves identically to ask_pipeworx, and the five Polymarket tools (arbitrage, edges, bet_research, fill_risk, edge_tracker) overlap heavily in the 'should I bet on X' use case. The detailed descriptions help, but an agent could easily misselect between these clusters.

Naming Consistency2/5

Naming is highly inconsistent: verb_noun (ask_pipeworx, compare_entities, resolve_entity), noun_noun (entity_profile, table_meta, polymarket_edges), single verbs (remember, forget, recall), and brand-prefixed compounds (pipeworx_trending, polymarket_kalshi_spread) are all mixed together. The server name 'Stat Gl' also doesn't align with the Pipeworx-heavy tool set.

Tool Count2/5

34 tools is well beyond the 25+ threshold that signals an oversized surface, and the set spans disparate domains: data querying, prediction markets, entity research, memory, subscriptions, and even niche utilities like generate_llms_txt and scan_dependency. While each tool has a described purpose, the count feels bloated for a coherent server.

Completeness4/5

Within its actual domains, coverage is strong: query, grounded verification, deep research, claim validation, entity profiles, comparisons, memory CRUD, and subscription lifecycle are all present, plus a complete Statistics Greenland browse/schema/query trio. Minor gaps exist (e.g., limited subscription event types, US-centric company profiles), but agents can typically find a working path without dead ends.
