Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.10.0
Disambiguation5/5
Each tool has a clearly distinct purpose, targeting different resources such as oracle health, contracts, feed values, events, visions, and subscriptions. No two tools are easily confused.
Naming Consistency5/5
All tool names follow a consistent snake_case verb_noun pattern (e.g., get_feed_value, list_tokens, lookup_event_feed), making the set predictable and easy to navigate.
Tool Count4/5
17 tools is on the higher end but still well-scoped given the broad domain covering oracle health, contracts, feeds, events, visions, and subscriptions. Each tool has a specific, non-redundant role.
Completeness4/5
The tool surface covers core domain operations like health checks, feed values, event management, and vision data. Minor gaps exist, such as no tool for historical feed values or direct subscription cancellation, but the overall coverage is strong.
Average 4.2/5 across 17 of 17 tools scored. Lowest: 3.6/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It mentions 'recent' and 'pattern breakdown and stats' but does not explain what constitutes 'recent', pagination, or whether the operation is read-only. No disclosure on auth or rate limits.
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?
Description is concise and front-loaded, with no filler. However, it could be better structured (e.g., separate sections for purpose and args). Still, it's efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given an output schema exists, description needn't detail return format, but it misses context on time range for 'recent' and what 'pattern breakdown' entails. Parameter docs are good, but overall completeness is moderate.
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 0%, but the description adds meaning: token default is explained, case-insensitivity noted, and currently supported values listed (BTC, ETH). This goes beyond the schema's minimal info.
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 the tool retrieves recent Pythia Visions for a token, with specifics on pattern breakdown and stats. It distinguishes itself from siblings like get_visions_info or get_vision_payload by focusing on history and breakdown.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for checking recent visions by token but lacks explicit guidance on when to use this vs alternatives like get_visions_info or get_vision_payload. No when-not-to-use or prerequisite context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It indicates this is a retrieval of code (no mutation implied), but does not disclose any potential side effects, authentication needs, or rate limits. It adds minimal context beyond the basic purpose.
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?
Two sentences plus an args line: concise and to the point. No wasteful words. Could benefit from structured formatting, but overall efficient.
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 one optional parameter and an existing output schema, the description covers the essential purpose and parameter values. It does not need to explain return values since output schema exists. Completeness is adequate for a simple retrieval 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?
The schema has 0% description coverage for the 'tier' parameter. The description adds meaning by listing the allowed values: 'discovery', 'analysis', 'speed', or 'complete'. This helps the agent understand valid inputs beyond the schema's type-only specification.
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 states exactly what the tool does: 'Get Solidity code to integrate Pythia into a smart contract.' It uses a specific verb ('Get') and clearly identifies the resource, distinguishing it from siblings like get_contracts or get_events_guide.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or differentiation from sibling tools like get_contracts or get_events_guide.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It describes the return data categories but does not disclose behavioral traits such as authentication requirements, rate limits, or side effects. The read-only nature is implied but not stated explicitly, and the description lacks details on data freshness or system impact.
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?
The description is four sentences long, front-loads the main purpose, and provides essential details without extraneous information. Every sentence adds value, making it efficient and easy to parse.
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 parameters and presence of an output schema, the description is fairly complete. It explains the tool's purpose and output categories. However, it does not mention any prerequisites, such as authentication or data latency, which would enhance completeness for a system health overview 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?
The tool has zero parameters, and the schema coverage is 100%. According to guidelines, 0 parameters yields a baseline of 4. The description adds no parameter information, but none is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves a summary of all tokens with an operational overview. It lists specific outputs (system-wide stats, tokens grouped by status, etc.), which makes the purpose clear. However, it does not explicitly differentiate from sibling tools like get_token_feeds or check_oracle_health, which could provide overlapping information.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions the tool is 'useful for quickly understanding what Pythia covers and whether the system is healthy,' which implies when to use it. However, it does not provide explicit guidance on when not to use it or mention alternatives among the 16 sibling tools, leaving the agent to infer usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description only mentions that prices are live, lacking details on rate limits, authentication, or other behavioral traits.
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?
Two concise sentences with front-loaded key information, though slightly terse.
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 no parameters and an output schema, the description adequately covers the tool's purpose; could mention return structure but output schema fills that gap.
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?
No parameters exist, so schema coverage is complete; the description adds no param info but is not required since there are none.
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 the verb 'Get' and the resource 'Pythia pricing tiers and free trial info', and distinguishes from siblings which focus on oracles, contracts, or events.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use or when-not-to-use guidance; usage is implied for fetching pricing data, but no alternatives are discussed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only says 'Plan... with cost and exact calls', which is vague about side effects (read vs write). It does not disclose whether a subscription is created, if there are costs incurred, or any authentication or rate limits. Minimal behavioral transparency.
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?
The description is concise: a short introductory sentence followed by a clear, bullet-like list for each parameter. No redundant information. Every sentence adds value, and the key purpose is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters and no annotations, the description covers the basics but lacks behavioral context (e.g., whether it's a read or write operation). An output schema exists but is not referenced, though that is acceptable per guidelines. The description does not address the presence of many sibling tools, leaving potential confusion about when to use this one.
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?
The description compensates for 0% schema coverage by providing clear explanations for each parameter: feed_name with examples, condition with enum mapping (0-3), and days with range. This adds significant meaning beyond the raw schema, making it easy for an agent to understand parameter usage.
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 starts with a specific verb 'Plan' and resource 'Pythia Events subscription', clearly indicating the tool's purpose. It mentions cost and exact calls, providing further clarity. This distinguishes it from sibling tools like list_subscriptions (listing) and get_events_info (retrieving info).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage through examples and parameter definitions, but does not explicitly state when to use this tool versus alternatives. For instance, it does not contrast with list_subscriptions or get_events_info. Usage context is implicit, not explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description partially discloses behavior by listing returned data, but does not mention side effects, read-only nature, or potential limitations, leaving some behavioral traits unclear.
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?
The description is extremely concise—two sentences plus a clarifying line—with the purpose front-loaded. Every sentence adds value without redundancy.
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 simple, parameterless tool with an output schema, the description covers the tool's purpose, return categories, and conceptual context (event subscriptions). It is complete enough for agent invocation.
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?
The tool has zero parameters, so baseline is 4. The description adds value by clarifying the tool's purpose and output, which is sufficient given no parameters to describe.

Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter engine_id is explained with examples ('bitcoin', 'solana', etc.) and a reference to list_tokens() for valid values. This adds significant value over the schema, which has 0% description coverage.
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 'Get all available indicator feeds for a specific token', providing a specific verb and resource. It distinguishes from siblings by focusing on listing available feeds rather than fetching values or managing subscriptions.
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?
It explains that feed names are used for oracle requests and instructs to use list_tokens() for engine IDs. However, it does not explicitly specify when to use this tool over alternatives like get_feed_value.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility. It discloses key behavioral traits: returns per-token 30-day uptime sorted worst-first, daily history, data source health, and infrastructure status. No contradictions present.
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?
Two sentences with zero waste: first sentence states core purpose, second lists what is returned. Front-loaded and efficient, every sentence earns its place.
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 zero parameters, presence of output schema, and the tool's simple nature, the description provides all necessary context: what it checks, what data it returns, and when to use it. Complete and sufficient.
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?
The input schema has no parameters, so description does not need to explain them. It adds value by detailing the output components, effectively compensating for the lack of parameters. Baseline is 4 due to high schema coverage (100%).
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 the tool checks the reliability and uptime of Pythia's oracle system, using specific verbs and a distinct resource. It differentiates from sibling tools which focus on contracts, events, feeds, etc., leaving no ambiguity about its role as a health check.
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?
Explicitly advises using this tool to verify reliability before integrating or relying on data. While it does not give when-not-to-use or alternative tools, the context is clear and sufficient for the agent to decide.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It transparently states it returns only active subscriptions and defines 'active' (not yet fired, expired, or cancelled). It also outlines return sections. Lacks details on side effects or rate limits, but for a read operation, it is sufficient.
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?
The description is well-structured with clear paragraphs and Args/Returns sections. It is concise, providing all necessary information without superfluous 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 the tool's simplicity (one parameter, single purpose), the description comprehensively covers purpose, parameter, return value, and use case. The presence of an output schema further reduces the burden.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides only title and type for 'owner_address', with 0% schema description coverage. The description compensates fully by explaining it is the subscriber wallet address and case-insensitive, adding critical semantic meaning.
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 the tool enumerates active Pythia Event subscriptions for an address, specifying the resource (subscriptions), action (enumerate), and scope (active=true). It distinguishes from the alternative of replaying logs, making the purpose unambiguous.
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 explains when to use the tool (to discover current subscriptions) and provides context on the inefficiency of alternatives (replaying logs). While it doesn't explicitly list when not to use or compare with sibling tools like 'subscribe_info', it gives clear usage guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses that the tool returns a multi-section text report and how it handles missing vision_ids. While it doesn't mention side effects, authentication, or rate limits, the description is sufficiently transparent for a read-only data retrieval tool.
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?
The description is well-structured with separate sections for what the tool returns, comparison to alternatives, args, and return behavior. It is concise yet comprehensive, with no wasted sentences.
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 that the tool has an output schema (context indicates it exists), the description does not need to fully detail return values. It summarizes the output effectively and explains fallback behavior. The description fully covers the necessary context for a single-parameter 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?
The single parameter vision_id has 0% schema description coverage. The description adds meaning by stating it is an integer id returned by get_vision_history, which provides extraction source. This compensates for the lack of schema description.
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 explicitly states the tool gets the full enriched object for a fired Pythia Vision by id. It details the contents (pattern metadata, failure profile, etc.) and clearly distinguishes between lightweight on-chain consumers and AI agents, the latter being the intended audience. This provides a specific verb-resource combination with differentiation from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance: 'AI agents reasoning about a specific Vision should use this tool' and contrasts it with on-chain decoding. It also notes that if vision_id is not in the recent window, the tool returns a helpful pointer to history. This tells the agent when to use this tool and what to expect.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses reading from live cache updated every cycle, describes return structure (value, computed_at, chain, multi-chain behavior), and explains diagnostic pointers for missing values. This fully informs the agent of behavior.
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?
The description is concise yet comprehensive, using clear sections and bullet points. Every sentence adds value without verbosity. Front-loaded with purpose and immediately useful examples.
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 single-parameter tool with an output schema (indicated by context signals), the description covers purpose, usage, parameter format, and return behavior completely. No gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description fully compensates by providing explicit examples ('bitcoin_RSI_1H_14', 'pol_EMA_5M_20') and clarifying the 'full feed name' format. This adds significant meaning beyond the schema's simple type and title.
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 'Get the latest computed value of a Pythia indicator feed' with a specific verb and resource. It distinguishes from sibling tools like get_market_summary and get_vision_payload by targeting feed values specifically, and contrasts with on-chain usage.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when off-chain AI agents should use this tool (reasoning about Vision context, choosing Event thresholds, sanity-checking) and provides a clear alternative for on-chain consumers (oracle.request() via get_integration_guide). This is excellent guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
