Server Quality Checklist

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

Latest release: v0.1.0
Disambiguation5/5
Each tool targets a very specific circuit design or analysis task, with detailed descriptions that prevent overlap. For example, edge_metrics, periodic_metrics, and pulse_response each handle distinct transient phenomena. Even tools that might seem similar, like simulation_summary and measurement_stats, serve different purposes (overview vs. aggregated .MEAS results).
Naming Consistency4/5
Names follow a mostly consistent verb_noun pattern for actions (add_component, run_simulation) but analysis tools use varied suffixes (_metrics, _stats, _summary) or are single words (resonance). The mix is still readable and predictable, with only minor deviations from a uniform pattern.
Tool Count2/5
48 tools is well beyond the typical 3-15 for a well-scoped server, indicating possible redundancy or over-specification. While the LTspice domain is complex, many tools could be merged or streamlined without losing functionality, e.g., combining several metrics tools into a single configurable analysis tool.
Completeness5/5
The tool surface covers the entire LTspice workflow: schematic editing, netlist creation, simulation setup and execution, result analysis (transient, AC, sweeps, Monte Carlo), library management, and validation. There are no obvious gaps; advanced features like diffing circuits and tracing nets are included. The set feels complete for the domain.
Average 4.2/5 across 48 of 48 tools scored. Lowest: 3.1/5.

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?
Annotations indicate idempotency and non-destructiveness, but the description adds no behavioral context beyond 'read or write'. It fails to disclose side effects like whether writing creates new directives or requires existing ones, leaving the agent unaware of important constraints.
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 a single concise sentence that efficiently communicates the core functionality with no wasted words. It is front-loaded with the verb and resource.
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 that an output schema exists and schema coverage is complete, the description is adequate but lacks important behavioral distinctions. It does not explain the conditional behavior of reading vs writing based on parameter presence, which is relevant for a dual-purpose tool.
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?
With 100% schema coverage, the baseline is 3. The description adds no parameter-specific meaning beyond what the schema already provides; the interaction between 'name' and 'value' (e.g., reading vs writing) is not clarified beyond the schema definitions.
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 reads or writes .PARAM directive values in circuit files, using a specific verb and resource. However, it does not explicitly distinguish from sibling tools like 'edit_directive' which might handle similar operations on other directives.
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?
The description provides no guidance on when to use this tool versus alternatives. It does not mention scenarios such as creating new parameters vs updating existing ones, or how it differs from editing directives via 'edit_directive'.
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?
Annotations indicate a write operation but no destructive behavior. Description adds no details about error conditions (e.g., duplicate reference), side effects, or need for prior schematic existence.
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?
Single clear sentence, front-loaded. Efficient but could benefit from a brief note on behavior or response format.
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 9 parameters and output schema present, description covers basic purpose but lacks constraints, error handling, and output description. Adequate but not comprehensive.
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 good parameter descriptions. The description adds no extra meaning beyond the schema, so baseline 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 description clearly states the action (add), the resource (component to .asc schematic), and the positioning (at specified grid position). It distinguishes from siblings like remove_component and move_component.
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 on when to use this vs alternatives (e.g., set_component_value, create_schematic). No prerequisites or context for selection.
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?
Description adds context that the label is placed 'at a wire junction' beyond annotations (idempotentHint, non-destructive). However, it lacks details on side effects, error conditions, or behavior of removing a label. Annotations already indicate idempotency and non-destructiveness.
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?
Single sentence efficiently states purpose and resource. Could include brief usage hint but remains front-loaded and to the point.
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?
Describes core action adequately but misses guidance on coordinate vs. pin usage, action parameter behavior, and no output schema. Sufficient for a simple tool but gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 67%, but description does not elaborate on parameters beyond schema. For example, 'path' parameter lacks schema description and is not mentioned in tool description. The description ties 'net' parameter to 'ground flag' but adds no new 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?
Description clearly states verb 'Add', resource 'net label or ground flag', and context 'to an .asc schematic at a wire junction'. It distinguishes from sibling tools like 'connect' or 'trace_net' by specifying the operation on net labels.
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 on when to use this tool versus alternatives like 'connect' or 'trace_net'. Does not mention when to use 'add' vs. 'remove' action, nor any prerequisites or constraints.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true, indicating a safe read operation. The description adds no behavioral context beyond what the schema and annotations provide. It does not mention pagination behavior, performance considerations, or error cases.
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 a single sentence of 18 words, front-loaded with the core functionality. Every word earns its place; there is no repetition or 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?
With 6 parameters, an output schema, and several sibling tools, the description is concise but lacks depth. It does not explain the two modes (list vs. single lookup) in detail, nor does it provide guidance on response structure or pagination. The presence of an output schema partially compensates, but the description could be more complete for agent decision-making.
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 adds context for 'prefix' (filter by type) and 'reference' (single component lookup), which aligns with the schema descriptions. It does not add meaning for 'path', 'offset', 'limit', or 'format' beyond what the schema provides.
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 it lists components in a circuit file with optional filtering by prefix or single component lookup. The verb 'List' and resource 'components' are specific. However, it does not explicitly distinguish itself from sibling tools like 'component_info' or 'query_value', but the purpose is still clear.
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 gives guidance on when to use filtering versus single lookup, but it does not mention when not to use this tool or provide alternatives. For example, it does not say to use 'component_info' for detailed component information or when to prefer 'list_components' over other listing tools.
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, destructiveHint=false, and idempotentHint=true, so the safety profile is clear. The description adds the scope of data returned, but no further behavioral traits (e.g., error handling beyond the schema note on 'step', performance, or output size). With strong annotations, the description does not need extensive behavioral disclosure, but it does not add significant value beyond them.
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 a single, well-structured sentence that immediately conveys the tool's core function. No wasted words, and it is front-loaded with the action and result. It is appropriately sized for its purpose.
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 is minimal but sufficient given the existence of a thorough input schema and annotations. It covers the essence of what the tool does. However, it could mention the requirement for a .raw file (though schema already marks 'raw_file' as required) or clarify the context of 'operating point' (e.g., from .OP simulation). The presence of an output schema helps, but a small addition would make it more 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 description coverage is 100%, so the schema already documents the three parameters thoroughly ('raw_file', 'step' with default and error behavior, 'format' with enum options). The tool description does not add any parameter-specific information beyond what the schema provides. Baseline score of 3 is appropriate.
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 uses a specific verb 'Read' and resource 'DC operating point data showing all node voltages and branch currents', clearly indicating what the tool returns. It is distinct from sibling read tools like 'component_info' or 'simulation_summary' by specifying the scope of the data. However, it does not explicitly differentiate from similar tools, and the title is null, so a slight deduction for not leveraging the title.
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?
The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or situations where another tool (e.g., 'simulation_summary' for summary metrics) might be more appropriate. The agent must rely on context and sibling names to infer usage.
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 indicate idempotentHint=true, readOnlyHint=false, destructiveHint=false. The description adds it returns a config_id but doesn't elaborate on side effects, persistence, or prerequisites.
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 single-sentence description is concise and front-loaded with the verb and resource, but could be slightly improved by noting the sibling relationship.
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?
Given the complexity (7 parameters, nested objects, no output schema), the description is too brief. It lacks an overview of the tolerance types and workflow, relying entirely on parameter descriptions.
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 thorough parameter descriptions, so the description doesn't need to add detail. It provides no additional meaning beyond the 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?
The description clearly states the verb 'configure' and the resource 'Monte Carlo analysis', and distinguishes from the sibling 'run_montecarlo' by noting it returns a config_id for later execution.
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 that this tool should be used before 'run_montecarlo', but lacks explicit guidance on when to use vs. alternatives (e.g., configure_sweep) or when not to use it.
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 destructiveHint=false, so the description's mention of 'Get' aligns. It adds that warnings are included but no further behavioral traits (e.g., about data freshness, caching, or performance). Given annotation coverage, the description provides modest additional context.
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?
Single sentence, front-loaded with key purpose and content list. Every word earns its place; no 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?
Given the complexity (5 parameters, output schema exists), the description adequately lists all major output components. No critical gaps for a summary tool.
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?
The input schema has 100% description coverage, so all parameters are documented there. The description does not add extra meaning beyond the schema, so baseline of 3 is appropriate.
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 it retrieves a comprehensive simulation summary with specific content types (type, signal list, data size, etc.), making the purpose evident. However, it does not explicitly distinguish itself from related sibling tools like bode_metrics or measurement_stats, which are more specialized.
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 on when to use this tool versus alternatives. The description implies it is for obtaining a broad summary after simulation, but lacks explicit context about preferred scenarios or exclusions.
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?
Description aligns with annotations (idempotentHint true, destructiveHint false). No additional behavioral context provided (e.g., permissions, file mutation details). Annotations already shed some light, so description adds minimal new insight.
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?
Single sentence, no wasted words. Front-loaded with key info. Could be slightly more structured but efficient overall.
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 4 parameters fully described in schema and no output schema, the description captures the core purpose. However, lacks details like file modification behavior or return value, which would improve completeness for a mutation tool.
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 covers 100% of parameters with descriptions. Description adds context about single vs batch mode, which maps to the parameters (reference/value vs values dict). Provides some added meaning but not extensive.
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?
Clearly states the verb 'Set' and the resource 'component value(s) in a circuit file'. Mentions two modes (single or batch), differentiating it from sibling tools like add_component or list_components.
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?
Implies batch vs single mode usage but lacks explicit guidance on when to use this tool over alternatives like set_component_attribute or batch_results. With many siblings, more direction would be beneficial.
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 destructive=true; description adds key behavior: automatic appending of .END if missing. No 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?
Short and to the point with two sentences, no wasted words. Could front-load more detail about overwrite behavior.
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?
Adequate for a simple tool but lacks mention of error handling, return value, or how it relates to sibling tools like validate_netlist.
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?

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?
Clearly states it creates a new SPICE netlist file from content string, and adds specific behavior (auto-appending .END). Distinguishes from sibling tools like export_netlist and schematic_from_netlist.
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?
Implies usage for creating netlist files, but does not explicitly clarify when to use this vs other creation methods or alternatives among siblings.
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 indicate destructiveHint=true and idempotentHint=true. The description adds that it uses LTspice, but does not explain what 'destructive' entails (e.g., file creation). Behavioral context is minimal beyond the schema and 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?
The description is a single concise sentence that conveys the essential information without any fluff. Every word is purposeful.
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 is largely complete: it explains the transformation (from .asc to .net). It could mention the output format more explicitly, but it is adequate.
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?
The only parameter 'path' has a clear description in the input schema ('Path to .asc schematic to export'), and the tool description repeats this without adding new meaning. With 100% schema coverage, the description adds no additional semantics.
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 exports an .asc schematic to a SPICE netlist (.net) using LTspice. It uses a specific verb ('Export') and resource ('.asc schematic') and distinguishes from siblings like create_netlist and schematic_from_netlist.
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 does not explicitly state when to use this tool versus alternatives like create_netlist or validate_netlist. The purpose is clear, but no guidance on when not to use it or context for choosing it over siblings.
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 provide minimal info; description adds loading into session but omits side effects like overwriting or cumulative 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?
Single sentence, no wasted words, clearly front-loaded with verb and resource.
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?

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers path with description; baseline 3. Description adds file extensions but no further parameter details.
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?
Clearly states the action (Load), resource (SPICE library file or directory), and context (into the session). Differentiates from siblings like list_libraries and unload_library.
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 guidance on when to use vs alternatives. Lacks prerequisites or exclusions; only describes behavior.
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 destructiveHint=true, and the description confirms the removal action. The description adds no contradictions but also does not elaborate on side effects beyond what the cleanup_wires parameter description covers. It is sufficiently transparent for a destructive operation.
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?

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 three parameters and no output schema, the description adequately states the core purpose. However, it could be improved by noting its relationship to sibling tools or specifying that removal is permanent.
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 schema already documents all parameters. The description does not add any additional meaning beyond the schema, so the baseline score 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 description clearly states the tool removes a component from a schematic by reference designator, which is a specific verb-resource pair that distinguishes it from sibling tools like add_component or move_component.
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, nor are there any prerequisites or exclusions mentioned. The description lacks context for decision-making.
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 provide idempotentHint=true; description adds 'previously loaded' context. No mention of side effects, permissions, or errors. Adds some value 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?

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'Unload', resource 'library', and context 'from the session'. Distinguishes from siblings like 'load_library' and 'list_libraries'.
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?
Implies usage after loading a library, but no explicit when-to-use, prerequisites, or alternatives provided.
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 provide idempotentHint=true and destructiveHint=false. The description adds the key behavioral detail that the tool returns a config_id for later execution, which is not in annotations. No contradictions.
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 a single, clear sentence that front-loads the purpose without any wasted words or redundancy.
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 adequately explains the tool's purpose and output given its two required parameters and no output schema. It could mention that the config_id is used with run_sweep, but the sibling tool list provides that context.
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 input schema already fully documents both parameters. The description adds no additional parameter semantics beyond what the 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 configures a multi-parameter sweep for a netlist and returns a config_id for later execution. It uses a specific verb and resource, and distinguishes itself from execution tools like run_sweep and configure_montecarlo.
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 this tool is for configuration, not execution, by mentioning 'return a config_id for later execution.' However, it does not explicitly state when to use this tool versus run_sweep or configure_montecarlo, leaving some ambiguity.
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?
The description discloses that the tool modifies files (add/remove) and specifies constraints like .asc-only for comments and remove behavior. However, with annotations providing no safety hints (all false), the description could add more about idempotency or side effects.
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 at three sentences, front-loaded with the main action, and contains no unnecessary words or repetition.
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 tool has 7 parameters (3 required) and no output schema, the description covers the essential high-level behavior and constraints. The schema fills in parameter details, making the overall definition adequately complete for an LLM agent.
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 adds little beyond the schema: it reiterates default kind and remove matching behavior, but does not provide new semantics for parameters not already covered in the schema descriptions.
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 adds or removes a SPICE directive or .asc free-text comment, with specific verbs and resources, distinguishing it from sibling tools that deal with components or other schematic elements.
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 provides useful context on when to use the tool, such as file type restrictions (.cir/.net vs .asc) and behavior differences for 'remove' action (matches both directives and comments). However, it does not explicitly compare with alternatives or state when not to use it.
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?
Discloses asynchronous execution and immediate job_id return, adding value beyond minimal annotations. No contradiction with 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?
Single sentence, front-loaded with verb and resource, zero waste. Perfectly concise.
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?
Covers purpose, async nature, and return value. No output schema, but description explains job_id. Could mention how to use job_id later (e.g., check_job), but not necessary.
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 already documents both parameters. Description adds slight context (source of config_id and default for max_parallel), but does not significantly enhance 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?
Clearly states the verb 'execute', the resource 'configured Monte Carlo analysis', and key details (asynchronously, returns job_id). Distinguishes from sibling tools like configure_montecarlo and run_sweep.
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?
Implies the tool requires prior configuration (previously configured), but does not explicitly list when to use vs. alternatives (e.g., run_sweep) or when not to use.
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 indicate this is a write operation (readOnlyHint=false) but not destructive (destructiveHint=false) and not idempotent (idempotentHint=false). The description adds the async behavior and immediate job_id return. However, it does not disclose that each call creates a new job, nor the lifecycle of the job or what happens if the config_id is invalid.
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?
Single sentence, 13 words, front-loads the core purpose and outcome. No redundant 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?
Given a simple tool with two well-documented parameters and annotations covering safety, the description is mostly complete. It lacks specification of the return format (e.g., job_id as string) and explicit linkage to check_job for monitoring, but still informative enough for an agent.
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?
Input schema has 100% coverage with descriptions for both parameters. The description does not add extra meaning beyond the schema; it mentions 'previously configured' aligning with config_id but doesn't elaborate on max_parallel beyond the schema's default note.
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 clearly states the tool executes a previously configured parameter sweep asynchronously and returns a job_id. The verb 'execute' and resource 'previously configured sweep' are specific. Differentiates from 'configure_sweep' (configuration) and 'run_montecarlo' (different simulation type).
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 that a sweep must be configured first (using configure_sweep) and that the execution is asynchronous, suggesting the user should later poll with check_job. However, it does not explicitly state when not to use this tool or mention alternatives like run_simulation for non-sweep runs.
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, destructiveHint=false, idempotentHint=true. The description adds that absolute positions can be optionally computed, which is useful context, but does not significantly expand beyond what annotations imply.

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema (not shown) and comprehensive annotations, the description adequately covers the tool's behavior. It mentions key return types and optional computation, though 'description' could be slightly ambiguous.
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 80% and most parameters have clear descriptions. The description adds meaning by explaining that x, y, and rotation are used for optional absolute position computation, clarifying their purpose beyond basic 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?
The description clearly states the tool retrieves symbol pin positions, bounding box, and description, with optional absolute position computation. This distinguishes it from sibling tools like component_info by specifying the exact data returned.
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?

It covers both modes, the filter, and implies the output includes status/results. The output schema handles return value details, so no further elaboration 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 description coverage is 100%, so the schema already documents each parameter. The description adds contextual meaning (e.g., job_id is returned by run_simulation, status filter options), but this is largely redundant with the schema descriptions. It does not provide new semantic information beyond what the schema already offers.
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?

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 destructive and idempotent behavior. The description adds important context: it kills simulator processes and marks the job as cancelled, which goes beyond the annotations. It does not mention error handling or side effects, but the core behavior is well communicated.
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 a single sentence with a parenthetical clarification. It is front-loaded with the action and resource, and every word adds value. No wasted or redundant content.

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 guidance: when to use each mode, when to use all_steps, when to use job_id vs raw_file, and directs to sibling tools for other analyses.
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?
The description provides extensive behavioral details beyond the destructiveHint annotation: it parses netlists, places components on a grid, connects via net labels, carries over directives, and notes label-based rather than routed wiring. It also explains the round-trip capability and how unsupported elements are handled. No contradictions with 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?
The description is a single, dense paragraph that front-loads the main purpose, then covers process, limitations, and round-trip capability in logical order. Every sentence adds value without redundancy, achieving high conciseness while maintaining 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?
Given the tool's moderate complexity (4 parameters, output schema exists), the description covers all essential aspects: what it does, input format, supported/unsupported elements, output characteristics, and response format options. The mention of skipped elements and round-trip integration with read_circuit provides adequate context for an agent to invoke it correctly.
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. The description adds value by explaining that the first non-blank line of 'content' is treated as a title and ignored, and lists supported element types. It also clarifies the 'name' parameter exclusion of '.asc' extension and the default behavior of 'overwrite'. This exceeds the schema descriptions.
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 generates an .asc schematic from SPICE netlist text, specifying verb (Generate), resource (.asc schematic), and input (SPICE netlist text). It distinguishes itself from siblings like 'create_schematic' by detailing its automated placement and connection process, and explicitly lists unsupported elements that are returned for manual handling.
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 this tool (to automatically generate a schematic from a netlist) and when not (for multi-terminal/subcircuit elements that require manual placement). It mentions round-tripping with read_circuit but does not explicitly compare to sibling tools like 'create_schematic' or provide 'when not to use' guidance, though the limitations are clear.
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 indicate read-only and idempotent behavior, but the description adds critical behavioral details: fuzzy matching behavior, return structure (ranked candidates with similarity score and .include directive), port and parameter inclusion, and a performance warning for include_builtin. No contradictions.
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 (5 sentences) and front-loaded with the primary purpose. Every sentence adds value, and the structure flows logically from purpose to behavior to parameter details. No wasted 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 output schema exists, the description still covers return values adequately (candidates, similarity score, .include directive, ports, params, optional full content). All 7 parameters are fully documented in schema, and the description provides necessary behavioral context for effective use.
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 description coverage is 100%, but the description adds significant meaning beyond the schema: it explains how fuzzy matching works, that exact=true bypasses fuzzy scoring, that limit/cutoff are ignored when exact=true, and that full=true merges the old model_info tool. This reduces cognitive load for the agent.
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 uses a specific verb ('Find') and clearly identifies the resource ('model/subcircuit candidates across loaded and optionally built-in libraries'). It distinguishes between fuzzy and exact modes, making the tool's primary function 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 explicitly states when to use fuzzy matching (default) vs exact matching (pass exact=true), and explains parameters like limit and cutoff are ignored when exact=true. It does not directly contrast with sibling tools, but the usage context is clearly implied within the domain of component search.
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?
The description adds behavioral details beyond annotations: what outputs are returned (min, max, mean, etc.), how axis choice works, and edge cases (single run with n=1). No contradiction with 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?

Parameters4/5
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 adds significant extra meaning: explains the difference between log_file and job_id, clarifies the measurement parameter, and describes histogram_bins' effect.
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 'aggregate' and resource '.MEAS scalar results', and distinguishes from sibling tools like simulation_summary by noting when to use each. Example questions ('worst-case rise time?') provide concrete context.
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 (aggregating across sweep or Monte Carlo) and when not to (use simulation_summary for plain single runs). Also explains axis choice and job type handling.
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 indicate readOnlyHint, destructiveHint, idempotentHint. The description adds crucial behavioral context: threshold crossing algorithm, auto midpoint behavior, rejection of AC analysis, and conditions for null duty_cycle_pct. No contradictions.
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?

Given 8 parameters, output schema exists, and complexity of periodic measurements, the description covers purpose, usage, edge cases, and behavioral details comprehensively. No gaps identified.
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. The description adds practical meaning beyond schema: e.g., threshold auto = midpoint, min_periods guards against 1-edge windows, t_start/t_end intended to skip startup transient. Adds moderate 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 tool is for oscillating transient signals to extract period, frequency, duty cycle, pulse widths, and jitter. It explicitly differentiates from the sibling tool edge_metrics ('For a single edge... use edge_metrics').
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 (periodic signals) and when-not (single edge), along with practical tips like skipping startup transient via t_start/t_end, setting explicit threshold for DC drift, and using min_periods to avoid insufficient data.
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 indicate read-only, non-destructive, idempotent. Description adds key behaviors: no interpolation, exact_match flagging, AC return structure (magnitude_linear). Minor omission: no mention of response format constraints beyond schema.
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?
Three concise paragraphs front-loading core purpose and behavior, then handling specific modes. No redundant text; every sentence adds essential context.
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?
Covers all major usage modes (standalone, step sweeps, AC, job runs) for a 9-parameter tool. Output schema exists, so return value details are adequately supplemented by the description's AC specifics.
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 100%, but description explains parameter relationships (e.g., step_axis+step_value, job_id+run_index) and runtime behavior (nearest step selection, AC return details), adding significant value beyond schema descriptions.
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 a signal value at a specific time or frequency, with 'nearest without interpolation'. It distinguishes from siblings by specifying the exact query operation.

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 structured with a summary followed by per-analysis sections, front-loading the purpose. While somewhat lengthy, the detail is justified by the complexity of four analysis types. 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 the complexity (four analysis types), full schema coverage, and presence of an output schema, the description covers all necessary aspects: what each analysis returns, parameter validity, and integration details. It is complete and reduces ambiguity.
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. The description adds extra semantic value by explaining how parameters like t_start/t_end behave differently depending on analysis type (e.g., rejected for AC), which goes beyond schema definitions.

Given the tool has an output schema, the description adequately covers return format and main behavior. It doesn't mention error conditions or edge cases like signals not found, but for a measurement tool with clear annotations and good parameter descriptions, it is sufficiently 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?
Schema covers 83% of parameters with descriptions. The description adds contextual meaning: explains that threshold_pct is applied per signal, direction parameters can be set independently (e.g., rising input to falling output). While helpful, it doesn't add substantial new information beyond schema for most parameters.
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 is for measuring propagation delay/skew between two signals, with specific examples like input-to-output delay and clock-to-Q. This differentiates it from sibling tools like edge_metrics or periodic_metrics that are for single-signal or repeated metrics.
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 usage context: 'Use when you need propagation delay / skew between TWO signals'. It also details prerequisites (transient .raw with both signals on shared time axis) and gives advice for handling multiple edges (tighten window). This clearly guides when to use and how to use effectively.
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?
The description discloses essential behaviors: expects a one-step transition in a transient .raw file, auto-detects initial/final values but allows explicit override if contaminated by ringing, defines metrics (overshoot/undershoot concepts), and notes that settling_time may be null if never settled. This adds substantial value beyond the readOnlyHint and idempotentHint 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

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 (9 parameters, 2 required, output schema present), the description is comprehensive. It covers input requirements, output fields, definitions of metrics, edge cases (auto-detection contamination, AC rejection), and alternatives. With an output schema existing, the description does not need to detail return structure but does so adequately.
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 descriptions are already detailed, but the tool description adds meaning by explaining the auto-detection logic (first/last 10% of window), the definition of overshoot and undershoot, and the interpretation of overshoot_pct=0 as measured overdamped. It also clarifies the role of settling_tolerance_pct with common values.
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 provides step-response quality metrics (overshoot, undershoot, settling time, peak value and peak time). It distinguishes itself from the sibling tool edge_metrics by noting that tool is for rise/fall time without overshoot.
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 to use the tool (need step-response metrics) and when not (for rise/fall time without overshoot, use edge_metrics). It also mentions that it rejects AC analysis, providing clear usage boundaries.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
