Server Quality Checklist

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

Latest release: v0.3.1
Disambiguation5/5
All 29 tools have distinctly different purposes, covering a wide range of embedded calculations without overlap. Each tool's description clearly defines its specific function, making it unambiguous for an agent to select the correct tool.
Naming Consistency5/5
Every tool follows the 'embedcalc_' prefix with a descriptive snake_case name (e.g., 'embedcalc_can_bit_timing', 'embedcalc_microstrip_impedance'). The naming pattern is consistent and predictable across all tools.
Tool Count4/5
With 29 tools, the count is on the high side but justified by the broad scope of embedded engineering calculations. Each tool provides a unique and useful calculation, and the number is reasonable for a comprehensive utility server.
Completeness4/5
The tool set covers many common embedded design domains (communications, power, signal integrity, component selection, etc.). Minor gaps exist (e.g., filter design, battery life), but the overall coverage is thorough and the most critical calculations are present.
Average 4.5/5 across 29 of 29 tools scored.

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

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral context beyond the annotations: it discloses that the result is rounded up to a power of two and provides a computed example. The annotations already indicate idempotent, read-only, non-destructive behavior, so the description complements them well 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 4 sentences, beginning with the core purpose, followed by parameters and an example. It is front-loaded and every sentence contributes meaning. No wasted 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 explains the computation, input parameters, and output structure. The output schema exists and covers return fields, so the description is complete for a calculator tool with this 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 coverage is 100%, so the baseline is 3. The description repeats parameter explanations but adds a concrete example demonstrating usage, which provides slight added 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 uses a specific verb ('Size') and resource ('ring buffer / DMA buffer'), and clearly distinguishes from sibling calculators by stating the computation formula. It is unambiguous and directly states the tool's function.
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 the tool should be used for sizing buffers from data rate and latency, and the sibling tools are all different calculators, so there is no confusion. However, it does not explicitly state when not to use it or mention alternatives, which prevents a 5.
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?
The description aligns with annotations (readOnlyHint, idempotentHint, destructiveHint) by presenting the tool as a calculation function with no side effects. It adds behavioral context: returns structured output, operates in CCM, and requires specific inputs. 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?
The description is concise, with a clear purpose statement, a parameter list, output format, and an example. Every sentence adds value. Slightly more structured formatting could improve readability, but it is effective.
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?

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 listing arguments compactly with defaults, explaining ripple_current_pct as a percentage of Iout, and providing a concrete example that clarifies units and expected values. This enriches the schema information.
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?

It specifies the operating mode (CCM) and distinguishes it from other embedcalc tools that handle different domains like resistors or wire.
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, nor does it provide exclusion criteria (e.g., for DCM). However, it gives a concrete example and references a sibling tool (embedcalc_eseries_nearest) for rounding, implying a workflow. This is adequate but not explicit.
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 readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description reinforces this by describing a pure computation and adds context about the estimate nature and verification recommendation, which is valuable beyond structured fields.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

The description clearly states it computes I2C pull-up resistor range, SCL timing budget, and STM32 TIMINGR register estimate. The verb 'Compute' and specific resources ('Rp min/max', 'SCL high/low', 'TIMINGR') make the purpose unambiguous. Among sibling calculators, this is distinct as the only I2C timing tool.
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 an example, lists arguments, and notes that the TIMINGR value is an estimate requiring production verification. However, it does not explicitly state when not to use this tool or compare to other calculators, which is acceptable for a specialized calculator.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Convert between float and signed Qm.n fixed point', specifying the verb, resource, and format. It distinguishes itself from sibling tools like IEEE754 converter by focusing on Q-format, making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context on the conversion direction and requirement to provide exactly one of value or raw_int. Examples further clarify usage. However, it does not explicitly address when to use this tool versus alternatives (e.g., for other fixed-point or floating-point conversions), though the name and title already imply its niche.
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?
Beyond annotations (readOnlyHint, destructiveHint, idempotentHint), the description explains the computational behavior: it applies 32-bit MCU model rules, returns structured output with offsets, padding, and nesting relative offsets. 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 appropriately sized: two paragraphs front-loading the core purpose and behavior, followed by clear arg/return details. Every sentence adds value.
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 of the tool, the description covers input format, supported features, output structure, and a usage warning. The output schema exists, which is not strictly needed but complements the description.
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 single parameter 'code' has 100% schema coverage, but the description adds meaning by specifying acceptable formats (member declarations or full struct), providing examples, and listing supported constructs (nested, arrays, pointers, bit-fields).
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 it computes memory layout of C struct/union, including member offsets, padding, bit-field packing, total size, and alignment. It specifies the target model (ARM Cortex-M style), distinguishing it from all sibling tools which are other calculator types.
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 context on when to use (when accurate memory layout is needed) and includes a warning against guessing sizes. It does not explicitly list alternatives, but no sibling tool serves the same purpose, so exclusion is unnecessary.
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?
Beyond annotations (readOnly, idempotent, non-destructive), the description discloses the search algorithm, tie-breaking rules, register encoding (BRP/TS 1-based, subtraction already applied), and null handling for no exact divisor. 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?
Well-structured with purpose first, then algorithm, arguments, return type, examples, and warning. Slightly long (~150 words) but justified by complexity; only minor redundancy in register encoding explanation.
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?
Comprehensive for a multi-controller timing calculator: covers algorithm, tie-breaking, register format, null returns, and example usage. Output schema exists, so return fields are not required in description. No gaps 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 coverage is 100% but description adds value: explains clock_hz per controller type (APB1 vs kernel vs Fosc), bitrate up to 1 Mbps for classic CAN, and sample_point_percent with CiA 301 recommendation (87.5). Examples illustrate realistic parameter 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 verb 'Compute exact CAN bit timing' and specifies three target controllers (STM32 bxCAN, FDCAN, MCP2515), distinguishing it from sibling calculation tools like embedcalc_spi_timing or embedcalc_uart_baud.
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 describes when to use (exact timing from clock, bitrate, sample point), what the algorithm does (searches all combinations, ties broken by TQ then BRP), and what null returns mean (change clock/bitrate). Warns 'Do not guess CAN timing registers — call this tool.'
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?
Discloses that the generated code embeds a check value for verification, and that it returns a structured object with check_hex, config, and c_code. Annotations (readOnlyHint, idempotentHint, destructiveHint) are consistent and not contradicted.
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?
Well-structured with clear sections: main purpose, usage, args, returns, examples. Every sentence adds value; no fluff.
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 (7 params, custom vs preset logic) and that an output schema exists, the description covers all necessary details: behavior, parameters, return format, and examples.
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?
While schema already covers 100% of parameters, the description adds meaningful context: explains the Rocksoft model, shows examples like poly_hex '0x1021', and clarifies that preset overrides all other args.
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 it generates a complete C implementation for CRC-8/16/32, including the standard check value. It uses specific verbs and resources, and distinguishes from other sibling embedcalc tools.
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 tells when to use a preset vs custom parameters, provides examples like 'MODBUS RTU CRC in C' mapping to 'CRC-16/MODBUS', and warns not to estimate CRCs but to call this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
