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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the primary behavior (change fader by relative dB) and adds valuable detail about the sign convention: 'Use a positive delta_db to raise and a negative delta_db to lower.' This explains how the parameter affects behavior. It does not disclose error handling, clamping limits, or prerequisites, but for a simple fader adjustment this is reasonable. The description goes beyond a bare statement of action by clarifying the delta semantics.

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

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

The description is two sentences with zero redundancy. The primary action is front-loaded in the first sentence, and the second sentence provides essential guidance on delta_db sign. Every word earns its place, making it highly concise and well-structured for quick comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter tool with no schema descriptions and an output schema (not shown), the description covers the core action and delta_db semantics but leaves gaps. It does not specify the source format (string vs integer), which is crucial for correct invocation. It also omits any mention of error conditions or limits (e.g., dB range). Given the tool's simplicity and the existence of an output schema, the description is adequate but not fully complete—it would benefit from a note on how to identify the channel.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage, so the description must compensate. It fully explains delta_db with the sign convention, adding meaning beyond the schema's bare 'number' type. However, it does not clarify the 'source' parameter beyond implying it identifies a channel; the anyOf type (integer/string) is left ambiguous—whether string refers to a channel name, ID, or alias is not specified. The description adds value for one parameter but leaves the other under-specified, resulting in partial compensation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action: 'Change a channel's main mix fader by a relative amount in dB.' It specifies the verb (change), the resource (channel's main mix fader), and the nature of the change (relative, in dB). This distinguishes it from siblings like xr18_set_fader_db (absolute) and xr18_adjust_send_db (send fader), though it doesn't explicitly name them. The phrase 'main mix fader' differentiates it from send faders, 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.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool: for relative adjustments, as opposed to absolute settings. However, it does not explicitly name alternatives or state conditions for selecting this tool over xr18_set_fader_db or xr18_adjust_send_db. The word 'relative' gives context, but the guidance is implicit rather than explicit, and no exclusions or when-not-to-use conditions are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description carries the full burden of behavioral disclosure. It does reveal the sign behavior ('Positive delta_db raises the level') and the accepted bus addressing forms. But it does not address clamping, error handling for invalid source/bus, persistence, or authorization requirements.

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

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

Two sentences with no redundancy: the first front-loads the core action, and the second delivers dense parameter and sign semantics. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has no annotations and a bare schema, making the description the primary guidance. It covers the complex 'bus' addressing well and clarifies delta behavior, but the unexplained 'source' parameter and lack of limit/error behavior leave the definition incomplete for fully correct invocation in all cases. The existence of an output schema covers return value expectations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema property descriptions are at 0% coverage, so the description must teach the parameters. It richly explains 'bus' (number, bus/5, fxsend/2, monitor/wedge, configured destination) and gives meaning to 'delta_db' (positive raises). However, 'source'—a required, polymorphic parameter—is entirely unexplained, which is a significant gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action: 'Change a source send level by a relative dB amount.' It clearly identifies the resource ('source send') and the operation ('relative dB amount'), which distinguishes it from siblings like xr18_set_send_db (absolute set), xr18_get_send_db (get), and xr18_adjust_fader_db (fader adjust).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'relative dB amount' and 'Positive delta_db raises the level' imply this tool is for relative adjustments, which helps an agent choose it over absolute-setting tools. However, it does not explicitly name alternatives or state when not to use this tool, leaving the contrast to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description carries the full behavioral disclosure burden, but it only restates the action and value scale. It does not disclose behavior for out-of-range values, clamping, validation, idempotency, permissions, or what happens when the source is invalid or unresolvable.

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

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

The description is a single concise sentence with no filler. The core action and value scale are front-loaded, and every word contributes to the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

While the tool has only two parameters and no output schema, the description omits important context: how source should be specified or resolved, whether values outside 0.0-1.0 are valid, and how this differs from the dB-based fader tools. The missing source semantics and lack of annotations leave a notable completeness gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It does add meaningful semantics for normalized_value by specifying the native 0.0-1.0 range, which is not in the bare schema. However, 'source' remains underdefined; the anyOf integer/string type is not clarified by the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action ('Set a source fader') and the value scale ('native normalized 0.0-1.0'), which helps distinguish it from the dB-based fader siblings. However, 'source' is not expanded, leaving some ambiguity about whether it refers to a channel, input, or bus.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The normalized-value wording subtly implies this tool is for setting faders in the 0.0-1.0 domain rather than in dB, and sibling tools like xr18_set_fader_db confirm that alternative. Yet the description never explicitly names alternatives or states when not to use this tool, so the agent must infer the routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

There are no annotations, so the description carries the full burden of disclosing behavior. It does clarify that the operation sets or clears mute state, which helps interpret the boolean 'muted' parameter. However, it does not disclose whether the operation is idempotent, whether the source must already exist, what errors occur, or what the response is. For a simple state-set operation this is acceptable but not rich.

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

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

The description is a single, front-loaded sentence that immediately states the action. It wastes no words and communicates the core purpose efficiently. The list of supported source types is compact and useful without being verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a low-complexity tool with only two parameters and no output schema, so a short description is reasonable. It covers the core intent but leaves the source addressing format ambiguous, which is important since 'source' accepts either an integer or a string. Without referencing helpers like xr18_resolve_channel or xr18_list_channels, an agent may guess incorrectly on how to specify a source.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds meaning by enumerating possible source categories (channel, AUX, FX, bus, LR, or DCA) and by associating the boolean with mute/unmute. Yet it does not explain the exact string or integer forms accepted by 'source', nor does it clarify whether 'muted' true means mute and false means unmute explicitly, though that is strongly implied.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action, 'Mute or unmute', and identifies the resource as a channel, AUX, FX, bus, LR, or DCA source. It is easy to distinguish from sibling tools like xr18_channel_set_fader or xr18_headamp_set_phantom because the action is explicit. However, it does not precisely define the accepted source format beyond listing categories, so there is some ambiguity in how to specify a target.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or excluded cases. A user could infer from the name and description that it is for muting, but there is no explicit context, exclusions, or alternative tool routing. This is effectively a bare action statement without usage direction.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It implies a read-only operation (validation and metadata retrieval) but does not state whether it has side effects, requires special permissions, or behaves differently for invalid paths. The description also doesn't clarify error handling or whether the tool is safe to call repeatedly. This is a significant gap given zero annotation coverage.

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

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

The description is a single, concise sentence with no extraneous words. It starts with the verb 'Validate' which immediately signals the action, and the object and outcome are clearly stated. It is appropriately sized for a tool with one parameter and a simple operation, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter) and the presence of an output schema (which is not shown but noted as existing), the description does not need to explain return values. However, it lacks context about when to use this tool, what the registry metadata includes, and how it relates to the sibling commands. The description is minimally sufficient for an agent to understand the basic function but lacks enough detail to make confident usage decisions without additional probing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It mentions 'concrete OSC path', giving a hint about the expected input format, but it does not define what constitutes a valid path, provide examples, or clarify whether paths are case-sensitive or have a specific structure. The parameter 'path' is only typed as a string with no additional context, leaving the agent to guess the expected value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('validate') on a resource ('concrete OSC path') and the result ('return its registry metadata'). This is distinct from sibling tools like get/set/trigger, which perform operations rather than validation. However, it doesn't explicitly differentiate itself from xr18_list_commands, which might also return metadata, leaving some ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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. There is no mention of prerequisites, typical use cases, or conditions under which a different tool (e.g., xr18_list_commands) would be more appropriate. The agent must infer usage solely from the tool name and description, which is insufficient.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations provided, the description carries the behavioral burden. It discloses the time-limited nature of the update window and the need for repeated calls, which are the most important operational traits. It does not discuss side effects or authorization, but the core behavior is clearly exposed.

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

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

The description is a single sentence that front-loads the action and duration, then states the follow-up requirement. Every phrase adds useful information, with no filler or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool with an output schema, the description is nearly complete: it names the action, the scope, the duration, and the keep-alive requirement. The only minor gap is not explicitly stating what happens if the periodic calls stop, but the ten-second window strongly implies deactivation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, so the input schema is empty and the description needs to add no parameter-level meaning. Per the zero-parameter baseline, this is appropriately handled.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Enable XR18 remote updates'), a time bound ('for ten seconds'), and the required follow-up behavior. This clearly distinguishes it from sibling tools like xr18_get, xr18_set, and xr18_trigger.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly instructs the agent to call the tool periodically to keep remote updates active, which is the key usage context. It does not name alternatives or exclusions, but for a straightforward enable-and-maintain tool this is adequate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get', implying a read operation, but does not explicitly state it has no side effects, nor does it describe error handling, return format, or connection requirements. This is a significant gap for a hardware-interfacing tool.

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

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

The description is a single short sentence with no redundant words. It front-loads the action and the key constraint (exact native OSC value) efficiently, making it easy to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has one parameter, no output schema, and minimal annotations, the description is sparse. It does not explain what a 'mixer parameter' encompasses, what the return value looks like, or how to construct a valid OSC path. While it may suffice for an expert, an agent would need more context to invoke it correctly across the sibling tool ecosystem.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has a single 'path' parameter with zero description coverage. The description adds that the path should be an 'exact, native OSC value', which clarifies it is an OSC address, but does not give format examples or accepted patterns. This partially compensates for the 0% schema coverage but is not comprehensive.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and the resource 'mixer parameter', and specifies the use of 'exact, native OSC value', which distinguishes it from set/trigger operations. However, it does not differentiate from sibling getters like xr18_get_send_db or xr18_get_fader_db, which may be more specific wrappers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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 the many sibling getter tools. It does not mention alternatives, conditions, or exclusions, leaving the agent to infer that this is the generic low-level getter without explicit routing information.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

The description's 'Read' does correctly signal a non-mutating operation, which is the primary behavioral trait. However, with no annotations provided, the description carries the full burden and does not disclose error behavior, return value semantics, or any constraints on 'source' beyond the schema.

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

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

A single, front-loaded sentence with no wasted words. It is appropriately concise for a one-parameter read tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is too sparse for a tool with an ambiguous 'source' parameter and no annotations. It does not clarify channel referencing, usage context, or how it relates to sibling read/write tools, so an agent would need additional inference or external knowledge to call it reliably.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for the undefined 'source' parameter, but it never mentions 'source' or explains how to identify the channel (integer vs. string). This leaves the only parameter effectively undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Read') and a specific resource ('a channel's main mix fader level in dB'), making the tool's function immediately clear. It also distinguishes itself from siblings like xr18_get_send_db ('main mix' vs. send) and xr18_set_fader_db/xr18_adjust_fader_db ('Read' vs. write operations).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explain when to use this tool instead of alternatives, nor does it mention exclusions. While the read/write contrast with set/adjust tools is implied, there is no explicit guidance about using xr18_get_send_db for sends or when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations at all, the description carries the behavioral burden. It clearly discloses a read-only operation and gives meaningful detail about accepted bus reference forms. It does not discuss error behavior, but for a simple read tool with an output schema, the core behavior is adequately transparent.

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

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

Two sentences with no filler. The operation is front-loaded and the bus value-space detail earns its place. This is appropriately concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema covers return values, but the description is incomplete for actually invoking the tool: one of two required parameters, 'source', has no documented semantics. The bus parameter is well covered, but a missing half of the required input surface makes the definition insufficiently complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description is the only documentation for parameters. It thoroughly explains 'bus' but leaves 'source' completely unspecified beyond the schema's anyOf integer/string. An agent cannot know what values to pass for the required 'source' parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Read a source send level in dB.' The read operation and the send-level resource clearly distinguish it from the set/adjust siblings and from the fader-level getter, so an agent knows exactly what this tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The verb 'Read' implies when to use the tool, but the description does not explicitly say to prefer this over xr18_set_send_db or xr18_adjust_send_db for writes. The bus-format guidance is about how to call the tool, not when to select it versus alternatives, so usage guidance is only implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations are provided, so the description carries the behavioral transparency burden. It does disclose an important guardrail: 'This requires confirm=true.' However, it does not mention consequences, error behavior when confirm is false, or the physical/irreversible nature of changing phantom power beyond the word 'physical'.

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

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

Two short sentences with no filler. The primary action is front-loaded and the confirmation requirement is stated immediately after, making the most important operational detail easy to spot.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations, no output schema, and two required parameters left unexplained, the description is too minimal. An agent would struggle to know what integer to pass for 'headamp' or what 'enabled' toggles, and there is no guidance on failure modes or return values.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description must compensate for undocumented parameters. It only clarifies the confirm parameter ('requires confirm=true') and says nothing about what 'headamp' represents or how 'enabled' controls phantom power. Required parameters headamp and enabled remain effectively unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Set') and a specific resource ('physical preamp phantom power'), which clearly identifies the tool's function. It is reasonably distinguishable from sibling tools like xr18_channel_set_fader or xr18_set, though it does not explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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 such as xr18_set or channel-level fader/mute tools. The only usage-related instruction is 'requires confirm=true', which is a prerequisite rather than a when-to-use guideline.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations are provided, so the description carries the full burden. It states the tool returns identity and firmware info, which implies a read operation, but it does not disclose behavior such as whether the 'extended' parameter changes the output shape, whether it requires a connection to the mixer, or whether it has side effects. The description is minimal and leaves behavioral traits undisclosed.

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

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

The description is a single sentence with no waste, and the core purpose is front-loaded. It is concise, though it could add a brief note about the extended parameter without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has one parameter with zero schema description coverage and no annotations, the description is incomplete. It does not explain the parameter's effect, the output format, or when to use this over xr18_status. An output schema exists, which covers return values, but the parameter semantics and usage context are missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain the 'extended' parameter. The schema only provides a boolean with a default of false, leaving the agent to guess what 'extended' means. The description should clarify that extended returns additional detail, but it does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb ('Return') and resource ('mixer identity and firmware information'), which distinguishes it from sibling tools like xr18_get or xr18_status. It lacks explicit differentiation from xr18_status, which may also return device info, but the specific mention of identity and firmware makes the purpose reasonably clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus alternatives like xr18_status or xr18_get. The description implies a read-only informational use case but does not state exclusions or conditions. An agent would have to infer when this is the right choice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations are provided, so the description carries the full burden. It implies a read-only operation through 'List' and discloses what's included, which is the key behavioral trait for a list tool. However, it doesn't explicitly state non-destructiveness, doesn't warn about potentially large responses from enumerating all strips, and doesn't clarify what happens for channels with no current fader state. For a simple read-only enumeration this is adequate but not thorough.

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

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

Two sentences with zero filler. The first sentence states the core action and return content; the second sentence efficiently enumerates the channel categories. The purpose is front-loaded and every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a simple parameterless tool with an output schema present, so the description need not explain return values — the schema covers that. The description covers what is included and the unit of the fader levels (dB). The only minor gap is a lack of explicit guidance on when to prefer this over sibling listing/reading tools, but for a zero-parameter enumeration tool this is essentially complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so the baseline for parameter semantics is 4. The description adds value by clarifying what the (parameterless) call will return — every named source strip with fader level in dB — and enumerating the channel types covered. There is nothing more a description needs to do for a no-parameter tool.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('List') tied to a concrete resource ('every named source strip') and names the return content (fader level in dB). It enumerates the exact scope ('regular channels, AUX, FX returns, monitor buses, FX send masters, LR, and DCAs'), which makes it distinct from siblings like xr18_read_meters (meter values) and xr18_get_fader_db (single fader). An agent can tell exactly what this returns without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The tool's purpose and scope are clear enough that an agent can infer when to use it (enumerate all strips) versus single-channel siblings like xr18_get_fader_db or xr18_channel_set_fader. However, it never explicitly names alternatives or gives an exclusion like 'use xr18_get_fader_db for a single fader' or 'use xr18_read_meters for meter data.' The guidance is implied by the naming convention rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description carries the full burden of disclosing behavioral traits. It states the action but does not explicitly declare the operation as read-only, nor does it mention any side effects, rate limits, or output details. The prefix usage is a behavioral hint, but the description lacks transparency about safety or potential consequences.

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

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

The description is a single, concise sentence that front-loads the core action ('List documented command templates') and then provides immediate usage guidance. There is no fluff, and every word adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple with one optional parameter and has an output schema that defines the return structure. The description covers the core purpose and parameter usage, but it lacks explicit guidance on when to use this tool versus siblings and does not state that the operation is read-only. Given the presence of an output schema, the completeness is adequate but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must explain the 'prefix' parameter. It does so by showing example prefixes and implying that the prefix filters the list. This adds clear meaning beyond the bare schema (a string with default). While not exhaustive, it effectively communicates the parameter's purpose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: 'List documented command templates.' It is specific about the resource (command templates) and provides usage hints with example prefixes. This distinguishes it from sibling tools like xr18_get or xr18_describe_command, which perform different actions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives concrete usage guidance for the prefix parameter ('Use a prefix such as /ch or /routing'), implying it filters results. However, it does not explicitly state when to choose this tool over alternatives like xr18_describe_command, which might also be used for command discovery. No exclusions or comparison with siblings are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations provided, the description carries the behavioral burden. It discloses useful behavior: results are in dB and channel indexing is zero-based with a 0-31 range. It does not explicitly state that the operation is read-only or describe any other side effects, but 'Read' and the meter context imply a safe query.

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

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

Two compact sentences deliver the essential scope and the critical indexing constraint without filler. The information is front-loaded and every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool with an output schema, the description covers the key invocation requirements: valid batch range, unit, and the conditional channel requirement. It does not specify what channel means for batches 1-9 or whether it is ignored, but the schema's default null and the stated batch-0 exception make the behavior reasonably inferable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds meaningful semantics: batch_id accepts 0-9, channel is zero-based with range 0-31, and channel is required specifically when batch_id is 0. This goes beyond the bare schema by clarifying valid ranges and conditional requirements.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the action (read) and resource (meter batch 0-9 in dB), which distinguishes it from generic tools like xr18_get and other channel/snapshot commands. It could be slightly more explicit about what a 'meter batch' represents, but the core purpose is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit guidance on when to prefer this tool over alternatives, and no sibling tools are mentioned. The only usage hint is the batch-0 channel requirement, which is parameter-specific rather than decision-oriented.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description is the sole source of behavioral disclosure. It does add value by stating the legacy name is retained and the result now contains the unified source identifier, which clarifies the return contract. However, it does not disclose behavior for unknown names, case sensitivity, name formats, or potential side effects—though this seems like a pure resolution tool, the lack of these details is a gap.

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

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

Two sentences, zero filler. The primary action is front-loaded, and the compatibility note is placed second. Every clause adds information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with an output schema, the description is reasonably complete, but it leaves operational details—valid name formats, error behavior, relation to the list tool—to be discovered. It is adequate as a minimal definition but does not fully equip an agent to call it correctly on the first try.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and there is only one string parameter, so the description must explain what 'name' means. Saying 'by name' and listing channel kinds is a start, but it does not specify the expected format (e.g., 'ch01', 'AUX1', user-assigned labels) or whether numbers are accepted. An agent will still have to guess or probe valid values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: it resolves a channel by name and names the full set of channel types it covers (regular, AUX, FX, bus, LR, DCA). It also tells the result is the unified source identifier used by other tools, which helps distinguish this from the get/set/trigger siblings. A small deduction because 'resolve' and 'unified source identifier' remain somewhat abstract without seeing the output schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or alternatives are given, but the phrase 'used by the other assistant tools' implies this is a lookup/helper tool. It does not say when to call this instead of xr18_list_channels or xr18_get, and no exclusions are mentioned. The intent is inferable but not spelled out.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description carries the full behavioral burden. It discloses the important detail that float controls use normalized 0.0-1.0 values, which is essential for correct invocation. However, it does not describe side effects (e.g., persistence, immediacy) or any failure modes, leaving gaps for a mutation tool.

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

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

The description is concise and well-structured: it opens with the core purpose, then provides a critical value-format detail, and ends with a safety precaution. There is no redundant text, and every sentence adds useful guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (2 params, no output schema, no annotations), the description covers the essential points: what it does, the value protocol, and a pre-check step. The path parameter may seem underspecified, but the explicit recommendation to use xr18_describe_command fills that gap, making the tool adequately self-contained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It explains the 'value' parameter for floats (0.0-1.0) but does not elaborate on the 'path' parameter beyond implying it is the OSC path of a registered parameter. This partial coverage gives some meaning but not enough for an agent to confidently form a path without additional lookups.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (set), the resource (a registered mixer parameter), and the method (using its native OSC value). It distinguishes itself from the many specialized setters by explicitly targeting generic 'registered' parameters, so an agent can tell it apart from tools like xr18_set_fader_db.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a clear procedural guideline: use xr18_describe_command before setting unfamiliar controls. This tells the agent when a prerequisite step is needed. However, it does not explicitly state when to choose this tool over sibling setters (e.g., generic parameters vs. dedicated fader/mute tools), so it lacks exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool 'set[s]' a value, implying mutation, but offers no additional context: no mention of the 'verify' parameter's effect, no side effects, no confirmation behavior, no permissions or preconditions (e.g., remote enable). The description is purely functional and lacks any behavioral depth.

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

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

The description is a single, concise sentence that is front-loaded with the key action and object. There is no redundancy or filler. It is appropriately sized for a simple tool, even though it lacks depth.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 3 parameters, no annotations, and zero schema description coverage, this description is severely incomplete. It does not explain how to specify the channel (e.g., numeric index, channel name), what dB range is valid, what the 'verify' parameter does, or whether any setup (like enabling remote) is required. The output schema exists but the input semantics are left ambiguous, making it difficult for an agent to call correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must explain parameters. It indirectly clarifies that 'source' is the channel and 'db' is the absolute dB value, which helps. However, it does not explain the 'verify' parameter at all, nor does it specify acceptable formats for 'source' (integer vs string) or any range/units for 'db'. This is only partial compensation for the missing schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (set), the resource (a channel's main mix fader), and the value (an absolute dB level). It distinguishes this tool from siblings like xr18_get_fader_db (read) and xr18_adjust_fader_db (relative change) by explicitly saying 'absolute'. The purpose is unambiguous and specific.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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 the many sibling tools (e.g., xr18_adjust_fader_db, xr18_channel_set_fader). It does not mention any conditions, prerequisites, or exclusions. An agent has no basis to decide between this and similar tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description carries the full burden of behavioral disclosure. It states 'Set' and 'absolute dB value', implying an overwrite, but does not explain effects on the mixer, idempotency, prerequisites, or the optional 'verify' behavior.

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

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

The description is a single, well-formed sentence with no filler. It is front-loaded with the primary action and resource, though it sacrifices useful detail for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given four parameters, zero schema descriptions, no annotations, and an output schema that is not shown, this tool needs more context. The description omits parameter formats, verification behavior, and operational prerequisites, leaving an agent to guess how to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds some meaning by indicating that 'db' is an absolute dB level and that the tool operates on a 'source send level', but it does not clarify what 'source' or 'bus' accept, what values are valid, or what 'verify' does.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description is specific: it names the verb 'Set', the resource 'source send level', and the value semantics 'absolute dB value'. The word 'absolute' usefully contrasts with sibling xr18_adjust_send_db, though it does not explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given for when to choose this tool over alternatives like xr18_adjust_send_db, xr18_get_send_db, or xr18_set_fader_db. The 'absolute' wording slightly implies a use case, but no explicit conditions, exclusions, or alternatives are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations, the description must carry the behavioral disclosure burden. It clearly signals a destructive action and the confirm gate, which is useful. Yet it does not disclose irreversibility, what happens if confirm is false, or any side effects, leaving important behavioral detail unstated.

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

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

Two short sentences with no filler or repetition. The core action and the critical prerequisite are both front-loaded, making the description easy to parse and act on.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter destructive command with no output schema, the description is nearly complete: it gives the slot range and the confirm requirement. It could be more complete by noting irreversibility or the no-op behavior when confirm is false, but these are minor given the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds meaning to both parameters: slot is constrained to 1-64 and confirm must be true for deletion to proceed. This goes beyond the raw integer/boolean types in the schema, though it does not fully describe confirm's default or behavior when false.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the exact action (Delete), the target resource (snapshot slot), and the valid range (1-64). It is clearly distinct from sibling snapshot tools like load, save, set_scope, and set_name, so an agent can identify the right tool without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives one explicit usage requirement: confirm=true. However, it does not explain when to choose this tool over alternatives, when not to use it, or provide any exclusion criteria. The usage guidance is implied by the tool name and sibling context rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

There are no annotations, so the description must disclose behavioral traits itself. It does not mention that recalling a snapshot overwrites current mixer state, whether the operation is destructive or reversible, or what prerequisites or errors apply.

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

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

One short sentence contains the action, target resource, and parameter range with no filler. The information is front-loaded and every word contributes.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter command, the description covers the core invocation details. However, with no annotations and no output schema, it omits usage context and side effects, so it is only minimally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema only declares slot as an integer with no description, but the description adds the essential valid range of 1-64. For a single required parameter this is sufficient guidance for correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb, recall, and a precise resource, snapshot slot, with a valid range of 1-64. This differentiates the operation from sibling tools like snapshot_save or snapshot_delete based on the action alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus snapshot_save, snapshot_delete, snapshot_set_scope, or snapshot_set_name. The agent is left to infer the intended use from the tool name and one-line description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations are provided, so the description must disclose behavioral traits itself. It only states the action and destination, but does not mention whether existing snapshots are overwritten, if the mixer must be connected, any prerequisites, or side effects. The lack of such detail for a mutating operation is a notable gap.

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

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

The description is a single, efficient sentence that gets straight to the point. It is front-loaded with the action and target, and contains no extraneous words. It is appropriately concise for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (one parameter, no output schema), so the description covers the basic purpose and slot range. However, it omits behavioral details like overwrite behavior and does not mention any prerequisites or connection requirements. For a mutating operation, this leaves some gaps, though the simplicity keeps it from being severely incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description is expected to compensate. It does add the valid range (1-64) for the slot parameter, which is useful and not present in the schema. However, it does not explain how the slot is used beyond the range, nor any constraints like uniqueness or behavior for invalid values. This partial compensation earns a middle score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action ('Save') applied to a specific resource ('current mixer state') and identifies the destination ('snapshot slot 1-64'). It is easily distinguished from sibling tools like xr18_snapshot_load or xr18_snapshot_delete because the verb and target are explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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 initial setup, periodic saves, or comparisons with load/delete operations. There are no explicit exclusions or references to sibling tools, leaving the agent to infer usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

No annotations exist, so the description carries the burden of behavioral disclosure. It only states the action; it does not disclose whether the name is overwritten, persisted, or validated, nor what side effects occur on the device. The description adds little beyond what the tool name already implies.

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

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

The description is very short and free of filler, with the action front-loaded. It is appropriately concise for a simple setter, though the phrasing is terse enough to create ambiguity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no annotations, a complete description should clarify that slot identifies a snapshot slot and that the name is being replaced on that snapshot. The current text is a minimal phrase that leaves the snapshot-slot relationship and mutation effects implicit.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for parameter meaning. 'Indexed' loosely maps to the slot parameter and 'name' to the name parameter, but it does not explain slot indexing semantics, slot bounds, or name constraints. This is only partial compensation for the missing schema documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Set') and a specific resource ('indexed snapshot name'), which distinguishes it from snapshot load/save/delete/scope operations. The phrase 'indexed' signals that snapshots are addressed by slot, but it is slightly vague and does not explicitly name the slot parameter.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given for when to use this tool versus alternatives like xr18_set or xr18_snapshot_set_scope. There is no mention of prerequisites, exclusions, or the context in which renaming a snapshot is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

There are no annotations, so the description must fully convey behavioral impact. It only says it sets a value, which implies a write/mutation operation, but it gives no detail on what recall-scope affects, whether the change persists, error behavior, or whether the slot and scope pair have constraints beyond the stated range.

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

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

The description is a single, front-loaded sentence that communicates the core action and a key constraint with no wasted words. It is appropriately sized for a simple two-integer-parameter command.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations, output schema, and schema-level parameter descriptions, the definition is too thin. It fails to explain the role of the slot parameter, the practical meaning of recall-scope, or any expected behavior/return value, so an agent cannot fully predict the tool's behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for both parameters. It adds meaning for the scope value by giving a range, but it never explains what 'slot' refers to or how slot and scope relate, leaving one required parameter entirely undefined.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb (Set) and resource (snapshot recall-scope index) and adds an exact range (0 through 59), making the tool's purpose unambiguous. This clearly distinguishes it from sibling tools like xr18_snapshot_set_name or xr18_snapshot_load, even without explicit comparisons.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is implied by the explicit action statement: if an agent needs to set a snapshot recall-scope, this is the tool. However, it does not state when to prefer this over alternatives or describe any prerequisites or exclusions, so guidance is only at an implicit level.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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

With no annotations provided, the description carries the behavioral burden. 'Return' implies a read-only action and names the outputs, but it does not disclose network dependency, failure behavior, or whether the data comes from a live device query.

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

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

The description is a single, front-loaded sentence with no filler. Every word adds meaning, and it is appropriately sized for such a simple zero-parameter tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the zero-parameter input and the presence of an output schema, the description covers the essential invocation context. It names the exact returned data, though a brief note on when to use it over xr18_info would make it fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, and the schema description coverage is 100% since the schema is empty. There is no parameter burden for the description to carry, so the baseline 4 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Return') and a clear resource ('XR18 status, IP address, and server name'). It is clear, though it does not explicitly distinguish itself from sibling tools like xr18_info.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The usage is implied: call this tool when you need the XR18's status, IP address, or server name. However, it gives no explicit guidance about when to prefer this over siblings 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.

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals that some operations need confirmation, but it does not explain side effects, whether actions are mutating/destructive, what happens when confirm is false, or any other behavioral consequences.

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

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

The description is short and not verbose, but the opening sentence is mostly filler. The second sentence about confirm adds useful context. Overall it is minimally structured but not egregiously wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the presence of an output schema, the description is severely incomplete for a generic trigger tool with an undocumented required path parameter. An agent cannot determine what paths are valid, what values mean, or how confirm affects execution, making this inadequate for reliable invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, but it only partially explains confirm. The required path parameter and the value parameter are completely unexplained in terms of valid formats, meaning, or examples.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Trigger an action' essentially restates the tool name and provides no concrete resource or domain. It does not distinguish this tool from specialized siblings like xr18_set or xr18_snapshot_load, leaving the agent to guess what kind of action is being triggered.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only usage guidance is that console initialization and network updates require confirm=true. There is no statement about when to prefer this tool over the many sibling tools, nor any exclusions or alternative routing guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
