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.

A4.8/5.0
Behavior5/5

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

The description exceeds what annotations provide by disclosing data freshness nuances (snapshots written on cache-miss, gaps mean no scan), the 60-day TTL history depth limit, and that decay is computed on the absolute value of edge_pp_net from daily closes rather than intraday. These are important behavioral traits for interpreting results.

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?

The description is well-structured with an introduction, a detailed RESPONSE section, and a LIMITS section. Every sentence contributes to understanding the tool's purpose, output, or caveats, and it is front-loaded with the core concept before diving into response structure.

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 fully compensates by detailing the response fields (tracked[], expired[], snapshot_dates[]) and their semantic meaning. It also covers data accrual, TTL, and decay methodology, making the tool's behavior comprehensible without needing to inspect code or other tools.

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?

Although schema coverage is 100%, the description adds meaning by explaining the days parameter as a lookback with default 14 and max 30 (aligned with the schema), and window as the snapshot family (24hr|1wk|1mo). It further clarifies that snapshots are written conditionally, aiding interpretation of the days/window interplay.

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 provides edge persistence and decay telemetry from daily polymarket_edges snapshots, answering a specific question about how long an edge has existed and whether it is shrinking. It distinguishes itself from the sibling polymarket_edges by focusing on historical time-series rather than current edges.

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 for when to use the tool, contrasting fresh vs. old edges ('the latter is wide for a reason nobody is willing to take') and explaining the response's purpose. It does not explicitly name alternative tools, but openly states the tool is built from daily snapshots and covers edge persistence, making usage context clear.

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

A4/5.0
Disambiguation4/5

Most tools have clearly distinct purposes with detailed usage guidance, but the several query entry points (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research) overlap conceptually and require careful reading to select correctly. Notably, ask_pipeworx_beta currently behaves identically to ask_pipeworx, which could cause confusion.

Naming Consistency3/5

Tool names mix verb-first (remember, resolve_entity) and noun-first (entity_profile, deep_research) patterns, with some using prefixes like 'polymarket_' or 'ask_pipeworx'. While all are snake_case and readable, the lack of a single consistent convention makes the set feel less coherent than it could be.

Tool Count3/5

33 tools is on the high end for a single server, though the broad domain (data retrieval, prediction markets, memory, subscriptions, web scraping) justifies much of the sprawl. Still, the count borders on heavy, and some tools could potentially be consolidated (e.g., the ask_pipeworx variants).

Completeness4/5

The toolset provides comprehensive coverage for its core data querying and analysis domain, with lifecycle coverage for memory and subscriptions. Minor gaps exist, such as no generic 'fetch page content' tool despite having get_metadata and take_screenshot, but these do not undermine the primary functionality.
