scan_bottoms

Scan the market and return coins currently at a bottom (most oversold / strongest buy), ranked most-bottom first. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free pitch tool tells you HOW MANY are at a bottom right now; this names them.

A4.5/5.0
Behavior4/5

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

No annotations provided, so description carries full burden. Discloses payment, trial, no account requirement, retry mechanism. Does not mention rate limits or side effects, but as a read-only scan, transparency is high.

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

Conciseness5/5

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

Every sentence serves a purpose: core function, payment, cold start, sibling tool relationship. Front-loaded with action, no redundant words.

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 complexity (payment, trial, tool relationships), description fully covers usage flow, prerequisites, and integration with 'pitch'. No output schema is needed for this tool.

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. Description adds value by explaining cold-start behavior (no symbol needed) and confirming defaults (limit 5, max 50), slightly clarifying 'symbols' parameter.

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?

Description uses specific verb ('scan') and resource ('coins at a bottom'), explicitly states ranking order ('most-bottom first'), and differentiates from siblings like 'scan_tops' and 'pitch'.

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 usage context: cold start without symbol, relationship to 'pitch' for count, and payment model. Lacks explicit when-not-to-use but effectively guides selection.

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
Disambiguation5/5

Each tool has a clearly distinct purpose: pitch for introduction, rate for feedback, subscribe for subscription management, evaluate_symbol for single-symbol analysis, and scan_bottoms/scan_tops for market-wide scans. No overlapping functionality.

Naming Consistency4/5

Most tools use a verb or verb_noun pattern with lowercase and underscores where needed (evaluate_symbol, scan_bottoms). pitch, rate, and subscribe are single-word verbs, which is consistent in style. The mix is minor and still readable.

Tool Count5/5

With 6 tools, the set covers the essential actions for a crypto signal service: introduction, single evaluation, market scanning, feedback, and subscription management. This is well-scoped and not overwhelming.

Completeness4/5

The major workflows are covered, including getting signals, scanning the market, and managing subscriptions. A minor gap is the lack of an explicit cancellation tool for subscriptions, but the existing tools provide a complete basic surface.
