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 annotations (readOnlyHint, idempotentHint, non-destructive), the description discloses important behavioral traits: snapshots are written only on cache-miss (leading to gaps), history is bounded by a 60-day TTL, and decay is computed from daily closes, not intraday data. This is substantial context that annotations alone do not provide.

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 well-structured with clear sections (purpose, args, response, limits) and every sentence contributes unique information. While it is longer than the two-sentence ideal, the elaborate phrasing reinforces the use case without redundancy, earning a high but not perfect score.

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?

Given the absence of an output schema, the description fully specifies the response structure: tracked[], expired[], snapshot_dates[], including field meanings and derived metrics. It also explains data freshness limitations and TTL, making the tool self-contained and complete for an agent to use correctly.

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%, and the description's parameter notes (defaults, max/clamp) essentially mirror the input schema. It adds no new semantic information about the parameters, so it sits at the baseline 3 for high-coverage schemas.

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 a specific question: 'how long has this edge existed and is it shrinking?' This is a distinct verb+resource with clear scope, and it differentiates from sibling tools like polymarket_edges by focusing on time-series persistence rather than current edge listings.

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 establishes its use case with the question 'how long has this edge existed and is it shrinking?' and explains why edge age matters, implicitly positioning it as a companion to polymarket_edges. However, it does not explicitly name alternatives or provide exclusion criteria, so it lacks the direct 'when-not-to-use' guidance that would earn a 5.

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

A3.5/5.0
Disambiguation2/5

Many tools have heavily overlapping purposes—ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are nearly identical, while entity_profile, compare_entities, and recent_changes all pull overlapping company data. The server is named 'Movies' but only 4 of 35 tools relate to movies, making it impossible to infer what the tool set is actually for.

Naming Consistency2/5

Naming is a mix of verb_noun (search_movies, get_tv_schedule), bare nouns (remember, recall), brand prefixes (pipeworx_*, polymarket_*), and ad-hoc verbs (ask_pipeworx vs validate_claim). There is no consistent convention; even the pipeworx family uses ask_ vs grounded vs beta suffixes that don't follow a predictable pattern.

Tool Count2/5

35 tools is heavy for a single server, and for a 'Movies' server it is extreme overkill since the vast majority have nothing to do with movies. Even if the intent was a general data/betting server, 35 tools exceed the upper bound of the well-scoped range and would be better split into focused servers.

Completeness2/5

As a movies/TV server it is severely incomplete: there is no get_movie, no reviews, no watchlist, no person/actor search—only search_movies, search_tv_shows, get_tv_show, and get_tv_schedule. If instead the domain is Pipeworx data, coverage is better but still lacks mutation tools (e.g., no create/update for subscriptions beyond subscribe/unsubscribe) and the movie tools become dead weight.
