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.

A4.2/5.0
Behavior4/5

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

Annotations already cover read-only, idempotent, not destructive. The description adds important behavioral details: how decay is computed (from daily closes, not intraday), response structure including tracked, expired, snapshot_dates, and gaps in snapshot data. No contradictions.

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

Conciseness3/5

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

The description is long but front-loaded with the core question. It contains useful detail on response format and limitations, but could be more concise. Every sentence adds value, but overall length is high.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

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 explains the return structure (tracked, expired, snapshot_dates) and edge cases (gaps, TTL). It addresses the complexity of the tool well.

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?

Schema coverage is 100%, so baseline is 3. The description adds context beyond schema: days default 14 max 30, window default '1wk', and explains their role in snapshot lookback and family. This adds meaningful value.

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 it provides edge persistence and decay telemetry from daily polymarket_edges snapshots. It distinguishes from sibling tool polymarket_edges by focusing on time-series analysis and answering 'how long has this edge existed and is it shrinking?'

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?

It explicitly provides context for when to use: to distinguish between a fresh wide edge and an old wide edge. It mentions limits like 60-day snapshot TTL and that snapshots run on cache-miss. While it doesn't explicitly say when not to use, the context is clear.

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

A4.3/5.0
Disambiguation4/5

Most tools have clearly distinct purposes, but there is some overlap among data query tools like ask_pipeworx, ask_pipeworx_grounded, deep_research, entity_profile, compare_entities, and recent_changes. However, detailed descriptions and different use cases help an agent distinguish them, so it is mostly clear.

Naming Consistency5/5

All tool names follow a consistent lower_snake_case pattern with a verb_noun style (e.g., ask_pipeworx, list_subscriptions, validate_claim). There are no mixed conventions, making it predictable and easy to understand.

Tool Count4/5

With 31 tools, the server covers a broad domain of data queries, prediction markets, memory, and subscriptions. While slightly more than typical, each tool earns its place and the count is reasonable for the comprehensive platform scope.

Completeness5/5

The tool surface is extensive, covering data querying, analysis, entity resolution, comparison, change tracking, memory, subscriptions, and more. There are no obvious gaps; it supports a wide range of user intents for the server's purpose.
