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.

A4.3/5.0
Behavior5/5

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

Annotations declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description goes beyond by detailing that the tool reads from daily snapshots, provides time-series data, computes trends (new, widening, stable, decaying) and decay rates, tracks expired opportunities, and mentions limitations like the 60-day TTL and that decay numbers are from daily closes, not intraday. This adds significant behavioral context.

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 fairly concise given the complexity of the output. It is front-loaded with the core purpose, then details parameters, response structure, and limitations. Some sentences are dense, but every part adds value. Could be slightly shorter, but overall well-structured.

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?

Given the absence of an output schema, the description thoroughly explains the response fields: tracked[], expired[], and snapshot_dates[]. It covers limitations and data sources. However, it does not define 'edge_pp_net' in detail (only mentions 'net of default slippage'), which might be insufficient for complete understanding. Otherwise, it is comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The tool description repeats the parameter names and defaults, adding slight context (e.g., 'max 30' for days, but schema already says 'clamp 2-30'). It does not elaborate further on parameter usage or formats beyond what the schema provides, so no extra value beyond baseline.

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 that the tool provides 'edge persistence and decay telemetry' and answers 'how long has this edge existed and is it shrinking?', using a specific verb ('track') and resource (edges over time). It distinguishes from sibling tools like polymarket_edges by focusing on time-series analysis 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 implies when to use the tool: to assess whether an edge is stale by checking its history. It includes the example that a 3-week-old wide edge is different from a fresh one. However, it does not explicitly state when not to use it or name alternative tools, though the context with siblings and the described limitations provide some guidance.

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

A4/5.0
Disambiguation3/5

Several tools have overlapping purposes: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are very similar, as are the suite of polymarket_* tools. While descriptions help differentiate, an agent may struggle to choose the correct one without careful reading.

Naming Consistency3/5

All tool names use snake_case, but they mix verb-first patterns (ask_pipeworx, compare_entities, validate_claim) with noun-first patterns (bet_research, entity_profile, pipeworx_feedback). This inconsistency makes it harder to guess tool names by convention.

Tool Count3/5

35 tools is on the high side but not unreasonable for a platform covering vulnerability queries, data retrieval, prediction markets, and utilities. However, the server name 'Osv' suggests a narrow focus, making the large count feel bloated.

Completeness4/5

The tool set covers a wide range of operations: querying data, comparing entities, managing user data, monitoring subscriptions, and even onboarding. Minor gaps exist (e.g., no direct API for updating user profiles), but overall it is well-rounded for its domain.
