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.

A4.4/5.0
Behavior5/5

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

Beyond the readOnlyHint/idempotentHint annotations, the description discloses behavioral details: snapshot-based data collection, cache-miss writing behavior, 60-day TTL, daily close basis for decay numbers, and signed edge values. This gives the agent a full understanding of what the tool returns and its limitations.

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?

Long but efficiently structured: purpose, args, response, limits in separate blocks. Each sentence adds functional value; no filler. The length is justified by the complexity of the response shape and edge cases.

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?

For a complex tool with no output schema, the description provides a comprehensive breakdown of the response fields (tracked[], expired[], snapshot_dates[]), field semantics (trend, decay_pp_per_day, lifespan_days), and limitations (TTL, sampling). This fully compensates for the lack of an output schema.

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 covers 100% of parameters, including defaults and valid ranges. The description restates 'days (lookback, default 14, max 30)' and 'window (snapshot family, default 1wk)' without adding new semantic meaning, so it doesn't elevate beyond the schema's thorough documentation.

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 defines the tool's function with a specific verb phrase ('Edge persistence and decay telemetry') and answers a concrete question ('how long has this edge existed and is it shrinking?'). It distinguishes itself from sibling tools like polymarket_edges by focusing on time-series persistence 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?

Provides clear context for when to use: when you need to assess edge age and decay trends, framing the distinction between fresh and stale edges. It gives response interpretation guidance ('median lifespan is your competition clock') but does not explicitly exclude alternatives for scenarios like current edge discovery, though that is implied by the existence of siblings.

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

Several tools have overlapping purposes: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, validate_claim, and bet_research all route questions to the same underlying engine, and ask_pipeworx_beta is explicitly identical to ask_pipeworx right now. The polymarket_* family also has many closely-related entry points, though descriptions do help differentiate them.

Naming Consistency4/5

Names consistently use snake_case with descriptive verb-first patterns (ask_, lookup_, scan_, validate_, resolve_, subscribe) and a clear polymarket_ family prefix. Minor inconsistency exists between lookup_city/lookup_zipcode and resolve_entity, and between noun-style names like entity_profile vs verb-style names like compare_entities, but the overall style is predictable.

Tool Count2/5

33 tools is heavy for a single server, and multiple could be consolidated: the ask_pipeworx variants and deep_research largely overlap, and the memory/subscription categories could be collapsed. For a data-platform gateway the breadth is arguably justified, but the visible redundancy makes the surface feel bloated rather than well-scoped.

Completeness4/5

The core domains are well covered: question answering has multiple modes, entity lookup has resolution and profiling, prediction markets have research/edge/arb/fill-risk coverage, and the memory (remember/recall/forget) and subscription (subscribe/list/unsubscribe/recent_alerts) lifecycles are complete. Minor gaps exist such as no direct tool to fetch a pipeworx:// record by URI, relying instead on MCP resources.
