Server Quality Checklist

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

Latest release: v1.0.1
Disambiguation4/5
Most tools have clear, distinct purposes, with detailed descriptions that help differentiate them. However, there are some overlapping pairs (e.g., base_columnDescription vs base_columnMetadata, base_tableList vs base_tablePreview) that could cause confusion if not read carefully.
Naming Consistency4/5
Tools follow a mostly consistent prefix_snake_case pattern (base_, dba_, graph_, plot_, qlty_, rag_, sec_, sql_). Minor inconsistencies in capitalization (e.g., rag_Execute_Workflow, sql_Analyze_Cluster_Stats) break the pattern slightly.
Tool Count2/5
With 47 tools, the server covers many distinct domains, but the count is excessive for a single MCP server. It exceeds the 'too many' threshold (25+) and could be simplified or split into multiple servers for better coherence.
Completeness4/5
The tool set covers a wide range of Teradata management tasks, including metadata, DBA operations, data quality, graph analysis, visualization, RAG, security, and SQL optimization. There are no major gaps for the intended purpose.
Average 4.4/5 across 47 of 47 tools scored. Lowest: 3.5/5.

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

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states that if persist=True, it 'materializes result as a volatile table and returns table name', implying a write side effect. However, annotations declare readOnlyHint=true and idempotentHint=true. The description contradicts these annotations by describing a potentially state-changing behavior. According to scoring rules, this contradiction results in a score of 1.
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 two paragraphs: first for purpose/usage, second for arguments. It is reasonably concise and front-loaded, though the argument list is redundant with the schema. No unnecessary sentences. Slightly verbose but acceptable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description omits what the summary statistics actually contain; it only says 'summary statistics for ALL columns' without specifying which statistics (mean, count, etc.). Since there is no output schema, the description should elaborate on the return format. Additionally, the contradiction with annotations creates confusion about the tool's side effects. For a tool with no output schema and a complex return, more detail is needed.
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 coverage is 100% (all three parameters described in schema). The description lists the arguments but only restates information from the schema without adding new semantics. Baseline is 3, and the description does not exceed this.
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 summary statistics for ALL columns in a table in a single call' and distinguishes from the sibling tool qlty_univariateStatistics for single column stats. The verb 'Get' and resource 'summary statistics for all columns' are specific and unambiguous.
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?
Explicitly provides when to use: 'when the user asks for an overview, profile, or summary of every field in a table.' Also provides when not to use and alternative: 'For detailed statistics on a SINGLE specific column... use qlty_univariateStatistics instead.' 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.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states it saves a file to disk, which is a write side effect, but annotations set readOnlyHint=true and idempotentHint=true, creating a contradiction. This undermines trust in the tool's 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 efficient: one sentence for purpose, one for usage rules, then argument list, then return info. Front-loaded with critical information, no fluff.
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?
The description covers purpose, arguments, and return format, and distinguishes sibling. However, the annotation contradiction undermines completeness, as the agent cannot trust whether the tool is read-only or not. Without output schema, the return description is adequate but not detailed.
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 description coverage is 0%, so the description compensates well. It explains each parameter (database_name, table_name with comma-separated bulk, object_type with defaults, output_dir with default) beyond the schema's just type and defaults. However, it could add more detail on acceptable values for object_type.
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 extracts DDL and saves it as a .sql file, distinguishing it from base_tableDDL which only displays DDL. The verb 'save' and resource 'DDL' are specific, and the sibling differentiation is explicit.
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 says to use this tool when the user wants to export/write/download/persist DDL to a file, and not to display/view DDL (use base_tableDDL instead). It also provides argument details and defaults, giving clear context.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true, indicating a safe, read-only operation. The description adds behavioral details beyond annotations, such as the ability to persist results as a volatile table via the 'persist' parameter, and the date range constraint.
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 concise with a clear purpose statement and usage guideline, followed by parameter definitions. It is front-loaded with the main purpose. Could be slightly more structured (e.g., separate sections), but it is efficient with no wasted words.
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?
The description explains what the tool does and its parameters, but does not describe the output format or content of the report (e.g., list of features, counts, etc.). With no output schema, additional detail on return value would improve completeness. The persist behavior is explained, but the default output is vague.
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 coverage is 100%, so the schema fully documents all parameters. The description repeats the parameter definitions, adding minimal value beyond a concise summary. It does not provide additional semantics or examples for parameters like start_date and end_date beyond format 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 clearly states the action ('Report') and the resource ('Teradata product features used during a specified date range'). It also lists specific use cases, effectively distinguishing it from sibling tools like other dba_ tools which focus on space, version, sessions, etc.
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 explicitly states when to use the tool: 'Use when the user asks about feature adoption, which Teradata capabilities are being used, or how feature utilization has changed over a period.' It provides clear context, though it does not explicitly mention when not to use it or direct to alternatives.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true. Description adds that persist=True materializes as volatile table and returns table name. 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.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is front-loaded with purpose and usage guidelines but then repeats parameter descriptions already present in the schema. Could be more concise by omitting the parameter list.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema. Description only hints at return value for persist=True. For default (persist=False), it does not explain what the tool returns. Missing details on result format or any limits.
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 coverage is 100% with each parameter having a description. The description repeats the same information for each parameter, adding no new meaning beyond the schema. Baseline 3 applies.
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?
First sentence clearly states the tool's purpose: 'Identify which users and tables are driving the most query and resource activity within a specific Teradata database.' This distinguishes it from sibling tools like dba_resusageSummary.
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?
Explicitly specifies when to use: 'Use when the user asks who is hitting a named database hardest' and when not to, with a direct alternative: 'For system-wide CPU, IO, and memory metrics... use dba_resusageSummary instead.' Also requires database name and advises to ask for clarification if missing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description implies write operations (e.g., 'Creates vector store', 'Creates cluster statistics'), but annotations set readOnlyHint: true and idempotentHint: true. This is a direct contradiction. The description does not disclose that the tool writes to the database, despite mentioning sufficient space in feature_ext_db.
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 long but well-structured with sections, bold headers, and bullet points. It front-loads the purpose and workflow. Some redundancy could be trimmed, but overall it's organized for readability.
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 complexity (multi-step pipeline), minimal input schema, and no output schema, the description provides extensive context: full workflow steps, performance metrics explanations, configuration details, prerequisites, and follow-up tools. It is highly complete.
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 0% description coverage, but the description explains that optimal_k controls the number of clusters and max_queries limits the top queries by CPU time. It provides meaning beyond the schema's raw parameter definitions.
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 'executes the entire SQL query clustering workflow' to identify high CPU usage queries. It distinguishes itself from siblings by detailing the full pipeline and referencing subsequent tools like sql_Analyze_Cluster_Stats and sql_Retrieve_Cluster_Queries as follow-ups.
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 includes an 'OPTIMIZATION WORKFLOW' section that explicitly tells when to use this tool and what tools to use after (e.g., sql_Analyze_Cluster_Stats). It also lists use cases and prerequisites, providing clear guidance on appropriate usage.
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?
Description adds behavioral context such as revealing natural JOIN relationships and data affinity patterns, and explains the persist parameter's effect of materializing a volatile table. Annotations already declare readOnlyHint and idempotentHint, so the description complements them without contradiction.
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 concise, front-loaded with the purpose, and includes usage guidelines and argument list in a clear structure. A small improvement could be organizing the argument list more formally.
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?
The description covers purpose, usage, and parameters, but lacks details about the output format or example results. With no output schema, more descriptive output would enhance completeness.
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%, so the baseline is 3. The description repeats parameter names and purpose but adds no additional meaning beyond what the schema already provides.
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 identifies co-occurring tables in SQL queries, revealing JOIN relationships and affinity patterns. It uses a specific verb 'Identify' and distinguishes from sibling tool base_tableUsage.
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?
Explicitly states when to use (queries about tables queried together, related tables, common workflows) and when not to (access frequency, query counts, per-user stats), directing to base_tableUsage as alternative.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true. Description adds context about the persist parameter materializing as a volatile table. No additional behavioral details beyond that, which is sufficient given the safety profile.
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?
Multi-line structure with clear main point and parameter details. Not overly verbose, though could be slightly more structured. Front-loaded with tool action.
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?
No output schema, so description should describe return format. It only mentions for persist case. For default list, no output description is provided, leaving the agent unaware of result structure (e.g., columns).
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?
Input schema has 100% description coverage. Description largely repeats schema but adds the clarifying question guidance for database_name, enhancing semantic value beyond schema.
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?
Verb 'List' + resource 'tables and views' + scope 'within a specific Teradata database or schema'. Distinct from sibling tools like base_databaseList (list databases) and base_tableDDL (get DDL).
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?
Explicit guidance on when to pass database_name vs omit, with a caution to ask clarifying question to avoid querying all databases. Lacks comparison to sibling tools but provides clear context.
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?
Annotations already declare readOnlyHint and idempotentHint. Description adds that persist materializes into a volatile table, providing extra behavioral context beyond annotations.
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 plus one argument description, all front-loaded. No wasted words; every sentence adds value.
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?
For a simple tool with one parameter and no output schema, the description adequately covers purpose and usage. Minor omission: does not explain what 'release information' includes, but acceptable.
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 coverage is 100% and the description repeats the same information as the schema parameter description. No additional meaning added beyond what schema provides.
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 returns Teradata database version and release information with a specific verb and resource. It distinguishes from siblings as no other dba tool focuses on version.
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 states when to use: 'Use when the user asks what version of Teradata is running on the system.' No exclusions or alternatives provided, but context is clear.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description need not repeat that. The description adds no additional behavioral context beyond the parameter effect (which is parameter semantics). A score of 3 is appropriate given the low burden but no extra disclosure.
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 (three sentences), front-loads the purpose, and uses clear structure. No unnecessary words.
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?
The description covers purpose, usage guidelines, and parameter. However, it omits what the tool returns when persist=False (presumably direct results but not stated). Given the tool's simplicity and lack of output schema, this is a minor gap.
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 coverage is 100% and the description's parameter explanation is identical to the schema's description. No added value beyond what the schema already provides. Baseline 3 for high 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 the tool shows total disk space usage across the entire Teradata system, aggregated over all databases. It differentiates from siblings by specifying use cases for system-wide vs. per-database vs. per-table queries.
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?
Explicitly states when to use this tool (warehouse-wide storage questions) and when to use alternatives (dba_databaseSpace for single database, dba_tableSpace for table-level). No ambiguity.
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?
Annotations declare readOnlyHint and idempotentHint, which the description does not contradict. The description adds detail on the persist parameter: 'materializes result as a volatile table and returns table name,' which is behavioral context beyond annotations. No additional traits like side effects or auth needs are discussed, but annotations already cover safety.
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: a concise purpose paragraph followed by a bulleted argument list. It is front-loaded with the main action. While slightly longer than necessary due to repeated parameter info, it remains readable and 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 no output schema, the description does not explain the return format (columns, structure) for the normal case. For persist, it notes returns table name. While annotations and schema cover safety and parameters, the missing output description leaves some ambiguity for the agent about what to expect from the response.
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%, so the baseline is 3. The description duplicates parameter docs in an Arguments section, reinforcing requirements like 'database_name - Required — do not pass empty string' and defaults. However, it adds no new semantic meaning beyond the schema; the persist description is identical.
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 'Show table-level disk space usage within a specific Teradata database, ranked by size.' It distinguishes from sibling tools by mentioning 'Use when the user asks which tables are largest' and contrasts with dba_databaseSpace and dba_systemSpace.
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?
Provides explicit when-to-use: 'Use when the user asks which tables are largest or consuming the most storage within a named database.' Also gives when-not-to-use: 'NEVER call this tool with an empty database_name' and instructs to ask for database if not provided. Alternatives are named: dba_databaseSpace and dba_systemSpace.
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?
Annotations already indicate read-only and idempotent. The description adds behavioral context about the 'persist' parameter materializing a volatile table and returning its name, which is useful beyond the annotations. However, it does not discuss authentication, rate limits, or other constraints.
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 a purpose paragraph and a parameter list. It is concise but covers essential points; could be slightly tighter but is effective.
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?
With no output schema, the description does not explain the return format (e.g., whether it includes timestamps, SQL text). While the purpose and usage are clear, a bit more detail on what the result contains would improve completeness. The parameters are fully described.
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%, so baseline is 3. The description repeats parameter names and gives brief explanations, which are nearly identical to the schema descriptions, adding minimal extra value.
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 action ('Retrieve SQL statements') and resource ('against a specific named table'). It distinguishes from the sibling tool 'dba_userSqlList' by specifying that this tool is for table-specific history, not user-specific history.
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?
Explicit guidance is given on when to use (user asks about queries on a particular table), when not to use (if table name not explicit, ask for clarification), and alternative tool (dba_userSqlList for user-specific SQL history).
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?
Given annotations already indicate readOnlyHint and idempotentHint, the description adds valuable context: it reads directly from the table without pre-fetching, and instructs not to use base_readQuery. This goes beyond mere restatement.
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 concise with 4 sentences, front-loading the purpose. It uses backticks for parameters and includes usage guidance. It is slightly longer than necessary but still efficient.
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 3-parameter tool with rich annotations, the description fully covers purpose, usage, parameters, and alternatives. It leaves little ambiguity for the agent, making it 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?
Schema coverage is 100% and the schema descriptions already specify each parameter's role. The main description integrates these roles but adds no new semantic information beyond what the schema provides. Baseline score of 3 applies.
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 'Generate a pie chart that reads directly from a Teradata table' with specific verb and resource. It distinguishes from siblings by explicitly referencing plot_polar_chart and plot_line_chart for alternative purposes.
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 tells when to use: 'when the user asks for proportions, shares, or how a total breaks down by category'. It provides explicit alternatives for polar and line charts, and warns against using base_readQuery. However, it does not exhaustively cover all sibling tools.
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?
Annotations declare readOnlyHint=true and idempotentHint=true, which the description does not contradict. The description adds behavioral context such as returning a list of affected column names and the effect of the persist parameter (materializing as a volatile table).
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 with two paragraphs: the first states purpose and usage, the second lists parameters in a clear format. No unnecessary words, front-loaded with key information.
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?
The tool has 3 parameters, one required, and no output schema. The description explains the return value (list of affected column names), the persist behavior, and usage context. It is sufficiently complete for the tool's complexity.
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%, so the baseline is 3. The description restates the parameter docs from the schema without adding new semantics beyond what is already in the structured field.

The description is well-structured with clear sections: purpose, performance, use cases, arguments, return format, and examples. It is front-loaded. However, it is relatively long; some redundancy exists in the performance section, but it's justified by the tool's complexity.
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?
Despite no output schema, the description includes a detailed return format with JSON example. All parameters are documented. The tool's relationship to siblings (composite vs individual) is clear. Context signals (6 params, no output schema) are fully addressed.
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?
Schema coverage is 0%, but the description compensates fully: each parameter is explained with types, defaults, examples, and critical warnings (e.g., container_pattern must be string, not array). The edge_repository parameter is described with a reference to another tool. This is exemplary.
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 as a composite graph analysis combining four individual analyses into one call, with a specific verb ('runs') and resource ('graph analyses'). It distinguishes from siblings (e.g., graph_bfsLevels) by highlighting the composite nature and shared edge fetch.
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?
Explicitly lists use cases such as full migration readiness assessment and dashboard data population. Contrasts with individual tools by noting performance benefits and suggests using this when 3+ individual calls would be needed. Includes example calls with different scenarios.
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?
Annotations already declare readOnly and idempotent. The description adds implementation details (pure-Python, Union-Find, single SQL SELECT) and clarifies no stored procedure, going beyond 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?
Well-structured with sections, parameters, and return structure. Every sentence adds value, though slightly verbose; could be trimmed slightly without losing clarity.
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?
