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?

The description extensively discloses behavior beyond the read-only annotations. It explains the response structure (tracked, expired, snapshot_dates), the meaning of expired (closed/resolved/arbed away), the signed nature of edge_pp_net (negative = SELL YES), and limitations (60-day TTL, daily closes not intraday). This goes well beyond the safety profile provided by the annotations.

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 intentionally organized into purpose, args, response, and limits. It is dense but every sentence provides value. While slightly long, the structure and front-loading make it efficient. The response key explanations justify the length.

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?

There is no output schema, so the description must fully explain the return format, which it does with field-by-field detail. It also covers edge cases (snapshot gaps, TTL bound) and the signed interpretation of the metric. For a complex telemetry tool, this is highly complete.

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?

Both parameters have 100% schema coverage. The description reiterates defaults and adds 'snapshot family' context for window, but this is marginal. It does not significantly deepen the understanding beyond the schema, so the baseline of 3 is appropriate.

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 opening sentence clearly states the tool's function: 'Edge persistence and decay telemetry built from daily polymarket_edges snapshots.' The rhetorical question 'how long has this edge existed and is it shrinking?' sharpens the intent, and the contrast with sibling tools like polymarket_edges is implicit through its focus 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 implies when to use the tool: to distinguish fresh edges from stale ones ('a fresh wide edge and a 3-week-old wide edge are different trades'). It also gives strategic context ('median lifespan is your competition clock'). However, it does not explicitly name alternative tools or state when not to use this one, so it stops short of a 5.

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

B3.4/5.0
Disambiguation1/5

The server is named 'Phishtank' but only one tool (check_url) relates to phishing. The remaining 31 tools cover a wide range of unrelated topics (data research, prediction markets, memory, etc.), many with overlapping purposes (e.g., ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research). This makes it extremely difficult for an agent to select the right tool.

Naming Consistency2/5

Tool names mix conventions inconsistently: some use underscores (ai_visibility_check, check_url), some are camelCase (ask_pipeworx, bet_research), and others are compound phrases. There is no predictable pattern across the set.

Tool Count1/5

With 32 tools, the count is high, but only one aligns with the server name 'Phishtank' (check_url). The vast majority belong to an entirely different domain (Pipeworx tools), making the tool count severely inappropriate for the server's stated purpose.

Completeness1/5

For a phishing detection server, the tool surface is severely incomplete. It lacks essential tools like report_phish, verify_phish, get_stats, etc. The single phishing tool (check_url) is insufficient, while the other 31 tools are completely out of scope.
