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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the session is local and that OAuth credentials are not exposed, which is useful but thin for a status tool; it says nothing about what state is reported or failure 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?

A single front-loaded sentence with no filler; the resource and the security constraint are both stated up front.

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 parameters and an output schema present, the description need not explain return values, and it is adequate for a simple status probe. The only minor gap is not indicating when the result should influence the agent's next action.

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 takes zero parameters, so the baseline is 4; there are no parameter semantics for the description to clarify. Schema coverage is 100% and there is nothing to compensate for.

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?

States a specific verb (Check) and resource (local TIDAL session), which is clearly distinct from the dozens of content-fetching siblings. It does not explicitly name a sibling it differs from, but the auth/status focus makes the scope obvious.

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 says what it checks but never says when to call it — e.g., before committing actions, or after an auth failure. No alternative tool or condition is mentioned, so usage must be inferred from the name alone.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, and an output schema exists, so the description carries a lower burden. Still, it adds nothing beyond those structured fields: no note about whether content is personalized, region-dependent, or requires authentication, which matters for an openWorld browse endpoint.

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 short sentence with no bloat and the action front-loaded. Its brevity is appropriate in form, though the sentence itself carries very little 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?

With zero parameters, an output schema, and safety annotations, the mechanical gaps are covered. What is missing is the distinguishing context against the many sibling browse pages (Home, For You, Genres, Hires, Mixes, Moods), which is exactly the information an agent needs to choose 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?

The tool takes zero parameters, so the baseline of 4 applies. There is nothing parameter-related for the description to compensate for.

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 (return the Explore page), but it essentially restates the tool name and gives no differentiation from near-identical siblings such as tidal_browse_home, tidal_browse_for_you, tidal_browse_genres, or tidal_browse_mixes. An agent cannot tell from this text why it would pick Explore over Home.

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 guidance on when to use this tool versus the other browse_* siblings, which is the central selection problem here given roughly ten browse tools in the list. No prerequisites, no conditions, no alternatives named.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds no behavioral context beyond the obvious read action—no mention of authentication requirements, rate limits, or what 'personalized' entails (e.g., depends on user history). It essentially restates the title.

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 sized for a simple, parameterless tool, though it could have included a brief usage hint without becoming bloated.

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?

An output schema exists, so return values need not be explained. However, with over 100 sibling tools including multiple browse endpoints, the description is too minimal to route an agent reliably—it lacks any indication of when the For You page is preferable to browse_home, browse_explore, or browse_mixes.

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?

There are zero parameters, so the baseline is 4. The description correctly does not introduce unnecessary parameter details, and the empty schema is self-explanatory.

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 a specific resource 'the personalized For You page', distinguishing it from generic browse tools by emphasizing personalization. However, it does not explicitly differentiate itself from the many sibling browse tools (browse_home, browse_explore, browse_mixes, etc.) beyond the 'For You' label.

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 offers no guidance on when to use this tool versus alternatives like tidal_browse_home, tidal_browse_explore, or tidal_recommend_tracks. An agent must infer that 'For You' is the right choice for personalized content without any explicit conditions or 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered by structured fields. The description adds nothing behavioral beyond that – no note on pagination, auth requirements, or what the hub page contains – and does not contradict the annotations.

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 short sentence with no filler, and the key info (genre-hub page) is front-loaded. It is efficient but nearly too terse to convey anything an agent couldn't read off the title.

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 annotations covering safety and an output schema covering return values, the description needn't explain results. But for a tool sitting among several similar genre/browse endpoints, the absence of any disambiguation or usage context leaves a real 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?

The tool takes zero parameters, so per the rubric the baseline is 4. There is no parameter syntax for the description to clarify.

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?

States a specific verb ('Return') and resource ('TIDAL's genre-hub page'), so the agent knows it fetches a curated genre page. However, it gives no differentiation from near-twin siblings like tidal_browse_local_genres, tidal_list_genres, or tidal_get_genre_items, leaving the agent to guess which genre endpoint it wants.

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 statement of when to use this versus the many other browse/list tools (tidal_browse_explore, tidal_browse_moods, tidal_list_genres). Usage must be inferred entirely from the name.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, and an output schema exists, so the safety and return-shape burden is largely carried by structured fields. The description adds nothing behavioral beyond that - no note on pagination, freshness, or what the page contains - leaving it at the minimum-viable level.

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 zero wasted words; it is efficient. It is slightly abrupt in that the one sentence carries no supporting detail, but it is not padded or redundant.

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-param browse call whose annotations and output schema cover safety and return structure, the definition is functional but thin: it does not say what the hi-res page yields or why an agent would pick it over browse_home, browse_explore, or a search. Given the size of the sibling set, a distinguishing clause would materially help.

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 takes zero parameters, so there is no parameter semantics to document and the baseline is 4. Schema coverage is 100% and there is nothing the description could add here.

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 names a specific verb and resource ('Return TIDAL's high-resolution audio page'), so the agent knows it retrieves a curated hi-res listing. However, it offers no differentiation from the large family of sibling browse tools (tidal_browse_home, tidal_browse_explore, tidal_browse_genres), so the agent must infer the distinction from the name 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?

There is no when-to-use guidance, no stated conditions, and no mention of alternatives such as tidal_browse_home or tidal_browse_mixes. With over a hundred siblings, the absence of any routing cue is a real gap.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The word 'personalized' hints that results depend on the authenticated user's context, which is mildly useful, but the description says nothing about auth requirements or the nature/scope of the content returned.

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 short sentence with no wasted words, appropriately sized for a zero-parameter call. It is front-loaded with the operation, though it is arguably under-specified rather than tight.

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?

An output schema exists, so return values need not be explained. However, for a personalized tool sitting among many similar browse siblings and requiring user context, the description leaves the critical routing question ('when Home vs for_you vs explore') unanswered.

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 takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. Schema coverage is 100% and no enum or nested-object complexity exists.

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 names a specific resource (the personalized Home page) with a clear verb, but it largely restates the tool name 'tidal_browse_home' and adds only the word 'personalized'. It gives no signal to distinguish it from close siblings such as tidal_browse_for_you or tidal_browse_explore, which are also curated/personalized browse surfaces.

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 when-to-use guidance at all. With a dense cluster of sibling browse tools (explore, for you, genres, hires, mixes, moods), the description never says why an agent should pick Home over those alternatives.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the vague term "localized" without explaining what localization means, whether authentication is required, or how the returned page behaves.

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. It is concise, though its brevity contributes to the ambiguity rather than resolving it.

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 many sibling browse tools, the definition is incomplete: it does not explain what a "localized genre page" contains or how it differs from tidal_browse_genres, tidal_list_genres, or tidal_get_genre_items. An output schema exists so return details are not required, but the missing sibling differentiation is a significant 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?

There are no parameters, and the rubric baseline for zero parameters is 4. The schema is empty and no additional parameter meaning is needed.

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 says the tool returns a "localized genre page," giving a verb and resource, but "localized genre page" is vague and is essentially a restatement of the tool name/title. It does not differentiate this tool from siblings like tidal_browse_genres or tidal_list_genres, leaving the agent to guess what makes this page distinct.

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 offers no guidance on when to use this tool versus alternatives such as tidal_browse_genres, tidal_list_genres, or tidal_get_genre_items. There is no explicit context, prerequisite, or exclusion 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and openness are covered. The description adds nothing beyond that: no statement about pagination, freshness, ordering, or what personalization depends on (auth/user context), which is the kind of context that would actually earn credit here.

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 short sentence with no filler and the key noun front-loaded. It is efficient, though its brevity comes at the cost of the differentiation noted elsewhere.

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 parameters, an output schema covering the return shape, and annotations covering safety, the description is minimally sufficient — an agent can invoke it correctly. It still leaves the agent unable to distinguish this browse entry point from the similar personalized-mix siblings, which is the main missing piece.

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 takes zero parameters, so there is nothing for the description to clarify; baseline 4 applies. The schema is empty and the description correctly implies a no-argument call.

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?

States a specific verb and resource ('Return the personalized mixes page'), so an agent knows this yields personalized mixes. However, it gives no differentiation from close siblings like tidal_browse_for_you, tidal_list_favorite_mixes, or tidal_get_mix, and 'page' is vague about whether it's a list, a hub, or a single mix.

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 when-to-use guidance, no prerequisites, and no mention of the many sibling alternatives (browse_for_you, list_favorite_mixes, get_mix). An agent must guess whether this or a sibling is the right entry point.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds no behavioral context at all – no mention of what the mood page contains, pagination, or result shape – leaving it purely a restatement of the resource.

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 waste, which is appropriate for a zero-parameter browse call. It is efficient, though arguably under-specified rather than maximally 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?

An output schema exists, so return values need not be explained. But for a browse tool sitting among dozens of similar browse siblings, the description gives an agent nothing to route on beyond the resource name, which is a real gap in completeness.

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 takes zero parameters, so there are no parameter semantics to document; the baseline of 4 applies. Nothing in the description could add detail here.

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?

States a specific verb and resource ("Return TIDAL's mood page"), so an agent knows this fetches the mood browsing page. However, it offers no differentiation from adjacent browse siblings such as tidal_browse_genres, tidal_browse_home, or tidal_browse_explore.

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 indication of when to use this tool versus the many other browse tools in the sibling list. No prerequisites, no exclusions, no alternatives named.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds no behavioral detail such as authentication needs, pagination, personalization, or what 'page' means in practice; it merely restates the title.

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 wasted words. It is efficient, though its extreme brevity means it carries very little information beyond the tool name.

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?

Because the tool has no parameters and an output schema exists, the description need not explain return values or arguments. However, in a suite of 100+ siblings with many browse_* and video-specific tools, it provides no help in deciding when this page is the correct one to call, leaving a major selection 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?

The tool takes zero parameters, so the schema is empty and there are no parameter semantics to document. Per the rubric, zero parameters establish a baseline of 4.

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?

States a verb ('Return') and a resource ('TIDAL's video page'), but the purpose is vague: it does not clarify what the video page contains or how it differs from siblings like tidal_get_video, tidal_get_artist_videos, or other tidal_browse_* pages. It is more than a bare tautology but still leaves the agent guessing at the actual scope.

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?

Provides no when-to-use guidance, no alternatives, and no prerequisites for choosing this browse page over the many other browse and video-related tools. The agent must infer usage entirely from the tool name.

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?

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=true, so the safety profile is covered. The description adds genuinely useful context beyond them by explaining the replay semantics in plain language ('a successful replay returns the stored result') and stressing that the commit targets one exact draft, which tells the agent the call is safe to retry.

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 padding; the commit action leads and the replay behavior follows. It is efficient, though the compressed phrasing ('action draft') is slightly cryptic without prior knowledge of the preview/commit pattern.

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?

An output schema exists, so return values need not be detailed, and the annotations carry the destructive/idempotent profile. Still missing for a generic, destructive commit endpoint is any indication of which action types it accepts or how it relates to tidal_commit_create_playlist, leaving an agent to guess about scope.

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?

Only one parameter, and the schema already documents it at 100% coverage ('Token from an exact preview'). The phrase 'one exact action draft' reinforces that the token selects a specific previously-previewed operation, but adds no format or sourcing detail beyond the schema, so the baseline of 3 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?

States a specific verb ('Commit') and resource ('one exact action draft'), making it clear this finalizes a previously previewed action rather than performing a read. It does not, however, differentiate itself from the sibling tidal_commit_create_playlist, nor does it hint at the range of actions commit covers, so an agent still has to infer the split from naming patterns.

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 guidance is given: it never says this must follow a tidal_preview_* call, nor when to prefer tidal_commit_create_playlist over this generic commit. The link to previews is only inferable from the schema's 'Token from an exact preview' note, not from the description itself.

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?

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered structurally. The description adds the genuinely useful nuance that this is a legacy compatibility path limited to create_playlist drafts, but it never explains what the commit alters or consumes, so the added context is thin.

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 short sentence with no filler, and the constraining clause ('restricted to create_playlist drafts') is placed where it is read. It is efficient, though its brevity shades into under-specification rather than pure conciseness.

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?

An output schema, annotations, and full param coverage mean the description can stay lean, and it mostly does. Still, for a destructive open-world commit that ties into a preview/commit workflow, the absence of any workflow or state-change explanation leaves a meaningful 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?

With a single parameter at 100% schema description coverage ('Token from playlist preview'), the schema carries the semantic load. The description adds nothing about the approval_token's origin or lifecycle, so the baseline 3 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 names a commit operation scoped to create_playlist drafts, and the title reinforces it, so the basic purpose is recoverable. However it leans on jargon ('backward-compatible commit alias') and never plainly says it finalizes a previously previewed playlist creation, leaving the agent to infer the semantics.

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 when-to-use guidance. The word 'alias' hints that tidal_commit_action is the modern counterpart and schema notes suggest a preview step precedes it, but the description never states that a draft must first come from tidal_preview_create_playlist or when to choose this tool over tidal_commit_action.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds that only public metadata is returned and that the lookup is exact (no fuzzy matching), which is useful but modest additional context; it does not discuss failures like invalid or unknown IDs.

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 efficient, though on the terse side given the large sibling surface it must be distinguished from.

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?

An output schema exists, so return values need not be described, and annotations cover the safety profile. What is present (public metadata, exact ID requirement) is adequate for a one-parameter read tool, though guidance on where to obtain an album ID is absent.

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% for the single album_id parameter, so the description must compensate. "exact album ID" usefully signals that an opaque ID is expected rather than a title string, but it gives no format example, source, or length guidance.

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?

States a specific verb (return), resource (public metadata for an album), and scope (one exact album ID). It is clearly distinct from the many get_album_* siblings like tidal_get_album_tracks or tidal_get_album_review, though it never names them explicitly.

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?

"one exact album ID" implicitly tells the agent this is an ID-based lookup rather than a name/browse entry point, so an agent lacking an ID would infer it should use tidal_search. However, there is no explicit when-to-use statement or exclusion against sibling album 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds that the payload is bit-depth/sample-rate pairs, which is modest extra context, but says nothing about the individual_tracks flag's effect or whether all tracks are covered.

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 zero filler, which is appropriately sized. It is arguably too terse given the undocumented parameter, but it is structurally clean.

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?

An output schema exists, so return values need not be described in prose. However, with a fully undocumented optional parameter and no usage context, the definition is only minimally sufficient for correct 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% and neither parameter is explained in the description. The required album_id is obvious by name, but the optional 'individual_tracks' boolean is completely opaque — the description gives no hint whether it changes the returned shape to per-track resolutions.

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?

States a specific verb ('Return') and resource ('bit-depth and sample-rate pairs for an album'), which is unambiguous. It implicitly distinguishes itself from the near-identical sibling tidal_get_track_audio_resolution via the album scope, but never names that sibling explicitly.

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 guidance on when to use this tool versus alternatives such as tidal_get_track_audio_resolution, nor any mention of prerequisites (e.g. auth or that album_id must be valid). The agent must infer usage entirely from the name.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe read. The description adds that the returned image is square and sized on request, which is useful context beyond the annotations, but says nothing about auth requirements, caching, or how the URL is consumed.

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 that states the resource and the size behavior. Efficient and free of filler, though it is arguably terse to the point of under-specification.

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?

An output schema exists, so return-value detail is unnecessary, and the annotations cover the safety profile. For a simple two-parameter state-read tool the description is nearly sufficient, with the only real omission being nothing critical.

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. "Requested square size" maps to the dimensions parameter and clarifies it is a square, but it omits the allowed range (80-3000) and default (1280) that the schema encodes only structurally. Album_id is implied by the tool name and schema requirement.

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?

States a specific verb and resource: it returns an album-cover URL, which cleanly separates it from metadata siblings like tidal_get_album. It does not explicitly contrast itself with adjacent image tools such as tidal_get_artist_image or tidal_get_video_image, but the resource (album-cover) 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 guidance on when to use this tool versus alternatives such as tidal_get_album (which may already carry cover data) or the other *_get_*_image tools. Usage is only implied by the tool name and 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds the useful facts that results are paginated and that the item list mixes in videos, but says nothing about ordering, page boundaries, or the sparse_album 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?

A single short sentence with the scope qualifier front-loaded; nothing is padded or restated from the title.

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?

An output schema exists so return values need no explanation, but for a 4-parameter paginated tool with zero schema description coverage, the description omits pagination semantics (defaults, max, how offset interacts with limit) and leaves sparse_album's purpose unclear. It is not adequate for correct 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% for all four parameters, so the description carries the burden and mostly fails: only 'page through' implicitly gestures at limit/offset, while album_id and especially the non-obvious sparse_album flag are left entirely 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?

States a clear verb+resource ('page through every album item') and adds a meaningful scope qualifier ('including videos') that distinguishes it from the track-only sibling tidal_get_album_tracks. It stops short of naming that sibling explicitly, so it is clear but not fully differentiated.

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 statement of when to use this versus tidal_get_album_tracks, tidal_get_album_video, or tidal_get_album_page. The 'including videos' clause is a scope hint the agent must infer into a selection rule rather than explicit guidance.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it does not say what a 'page' contains, whether it requires an authenticated session, or how it differs behaviorally from the plain album fetch.

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 filler; nothing redundant or padded. It is efficient, though the brevity comes at the cost of substance rather than being tight-but-complete.

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?

An output schema exists, so return-value documentation is not required, but the definition still leaves the core concept ('page') and the undocumented album_id unresolved. For a read tool with sibling overlap, it does not supply enough to call it correctly and confidently.

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 sole parameter album_id carries no description in the schema. The description does not compensate by explaining what form the album_id takes (TIDAL numeric ID vs. string) despite a 160-char maxLength hinting at a non-trivial identifier.

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?

States a verb ("Return") and a resource ("structured TIDAL page associated with an album"), so the basic action is identifiable. However, "page" is undefined jargon and the definition never distinguishes this from close siblings like tidal_get_album, tidal_get_album_items, or tidal_get_album_tracks, leaving an agent unsure what extra payload a 'page' provides.

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 when-to-use guidance and no alternative named. With three sibling tools operating on the same album_id concept, the agent gets no cue for choosing this tool over tidal_get_album or tidal_get_album_items.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one genuinely useful behavioral signal, 'when available', warning the agent that the review may be absent, but says nothing about whether the result is empty, null, or an error in that case, nor about any auth requirement.

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, front-loaded with the verb and resource, with zero filler. Nothing to trim and nothing buried.

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?

An output schema exists, so return structure needn't be described, and annotations cover the read-only, open-world nature. The only real gap is not telling the agent how this differs from tidal_get_album, which also takes an album_id, but for a simple single-param getter the definition is nearly 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 technically should compensate, but the single parameter is named album_id and is self-explanatory given the tool name. The description adds no format, source, or ID-provenance detail beyond what the name implies, so it lands at a baseline 3.

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?

States a specific verb and resource ('Return TIDAL editorial review text'), which is unambiguous and clearly separable from the many album-metadata siblings like tidal_get_album or tidal_get_album_tracks. It does not explicitly name an alternative sibling or clarify whether review text is also included in tidal_get_album, so a 5 is not warranted.

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 guidance on when to call this versus tidal_get_album or any other album tool, nor any prerequisites (e.g. does the album need to exist, is auth required). The only contextual hint is 'when available', which is a return-value caveat rather than usage guidance.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and external-query profile is covered. The description adds only a minimal behavioral detail: matches are resolved exactly and may return multiple albums ('matching albums'), with no mention of pagination, auth, or rate limits.

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

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

A single sentence that is front-loaded, contains no filler, and communicates the core action and input format efficiently. It is appropriately sized for a simple lookup 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, has an output schema for return values, and annotations cover its safety profile. However, with 0% parameter description coverage, the description should at least clarify pagination or usage boundaries; it currently leaves the agent to infer limit/offset behavior and does not distinguish the tool from other album retrieval methods.

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 should compensate for all three parameters. It meaningfully describes 'barcode' as an exact UPC/EAN, but says nothing about 'limit' or 'offset', leaving pagination semantics entirely undocumented in both schema and 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 gives a specific verb ('Resolve') and resource ('matching albums') with the identifying input ('exact UPC/EAN barcode'), making the tool's purpose unambiguous. It does not explicitly mention sibling alternatives like tidal_search or tidal_get_album, so it falls just short of the top score.

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 'exact UPC/EAN barcode' implies this tool should be used when the agent has a precise barcode rather than free-text search, but it offers no explicit when-to-use guidance, prerequisites, or named alternatives. Usage is inferred 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and openness profile is covered. The description adds the useful nuance that similarity is TIDAL's own determination (not a transparent genre/attribute match), but says nothing about result ordering, pagination behavior with limit/offset, or whether results can be empty.

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 filler; every word earns its place. It is efficient, though the brevity borders on under-specification rather than optimal conciseness.

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?

An output schema exists, so return values need not be described, and annotations cover safety. Still, with undocumented parameters and no usage routing, the definition is only minimally complete for a seed-plus-paging tool.

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 only implicitly maps 'seed album' to album_id and gives no meaning for limit or offset, leaving the paging parameters documented nowhere.

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 gives a specific verb (List) and resource (albums similar to a seed album), and the word 'similar' clearly signals algorithmic recommendations rather than album metadata. It does not, however, explicitly distinguish itself from the very close sibling tidal_get_artist_similar, leaving the agent to infer that this one is album-seeded.

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 guidance on when to reach for this tool versus tidal_get_artist_similar, tidal_get_track_radio, or tidal_browse_for_you. No prerequisites (e.g., needing a valid album_id) or exclusion conditions are 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the notion of paging, which is already implied by the limit/offset schema fields, and says nothing about defaults, ordering, or maximum paging 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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though its brevity reflects under-specification rather than disciplined editing, which is penalized in the other dimensions.

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?

An output schema exists, so return values need not be described. However, for a paginated read tool the description never clarifies pagination semantics or the sparse_album flag, and it gives no basis for choosing it over tidal_get_album_items.

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% across four parameters, so the description must compensate and does not. album_id, limit and offset are self-explanatory, but sparse_album is entirely opaque and is documented in neither the schema nor 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?

States a specific action and resource: paging through audio tracks belonging to one album. The word 'audio' implicitly separates it from tidal_get_album_video, but it does not distinguish it from the very similar sibling tidal_get_album_items or explain what 'page through' means beyond the pagination params.

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 when-to-use guidance and no mention of alternatives such as tidal_get_album_items or tidal_get_track. An agent must infer from the name alone that this is the tool for listing an album's track list.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one genuine behavioral fact — the URL may not exist ('when available') — but says nothing about auth requirements, rate limits, or fallback behavior when the video-art is absent.

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 tight sentence with no filler, and the qualifier 'when available' is placed where it matters. It is efficient, though efficiency here comes partly from omitting necessary detail rather than from disciplined editing.

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?

An output schema exists so return-value explanation is not needed, but the tool has an undocumented 'dimensions' parameter and is surrounded by many similar lookup tools with no differentiation. For a 2-parameter tool with zero schema coverage, the description is too thin.

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 carries the full burden and fails: it never mentions the 'dimensions' parameter (default 1280, range 80-3000) that controls the returned image size, nor the constraints on album_id. 'The album's' only loosely implies the album_id input.

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?

States a specific verb and resource: returns the album's video-art URL. However it does not distinguish itself from near-identical siblings such as tidal_get_album_image or tidal_get_video_image, and the phrase 'album video-art' remains ambiguous versus a regular album image.

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 cue is 'when available', which describes a possible outcome rather than a usage condition. There is no guidance on when to prefer this over tidal_get_album_image, tidal_get_video_image, or tidal_get_video_url.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that only 'public' metadata is returned, a useful scope note, but says nothing about auth requirements, rate limits, or behavior on missing IDs. With annotations carrying the burden, a mid score is appropriate.

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 tight sentence with the resource and scope front-loaded and no filler. It is efficient, though its brevity is partly the source of the coverage gaps elsewhere.

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?

An output schema exists, so return values need not be explained, and annotations cover safety. However, for a lookup tool sitting among ~15 other artist-scoped getters, the description does not help the agent route among them or state how to obtain the required ID, leaving meaningful gaps.

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 single artist_id parameter has 0% schema description coverage, so the description must compensate. 'one exact artist ID' usefully clarifies that the input is an exact internal identifier rather than a name or search term, adding meaning beyond the bare string type, though it omits the format/length expectations already present in the schema's constraints.

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?

States a specific verb and resource ('Return public metadata') scoped to 'one exact artist ID', which is clearer than a bare name restatement. It does not, however, distinguish itself from the many artist-scoped siblings like tidal_get_artist_bio, tidal_get_artist_page, or tidal_get_artist_top_tracks.

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 'one exact artist ID' implies the agent must already hold a resolved ID (e.g. obtained from tidal_search) rather than a name, which is a weak usage hint. There is no explicit when-to-use, exclusion, or named alternative for the artist-lookup siblings.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and network behavior. The description adds the pagination behavior ('Page through'), which is useful context beyond annotations, but omits auth needs, rate limits, or response structure.

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 that earns its place with no filler. It conveys the tool action and pagination scope efficiently.

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 list tool with an output schema and safety annotations, the description is minimally complete. However, with 0% schema description coverage, it should say more about pagination parameters and differentiate from sibling album-listing tools.

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 carry parameter meaning. It only implies pagination through 'Page through,' but does not explain limit, offset, defaults, or the artist_id format, leaving most parameter semantics to inference from names and constraints.

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 ('Page through') and resource ('an artist's main album discography'), which distinguishes it from sibling tools for EPs/singles and other albums. It does not explicitly name those siblings, but the scope is specific enough to identify the tool's job.

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?

Usage is implied by 'main album discography' and 'Page through,' suggesting this tool is for main albums with pagination. It does not explicitly state when to use it versus alternatives like tidal_get_artist_ep_singles or tidal_get_artist_other_albums, leaving the agent to infer.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network scope are covered. The description adds one genuinely useful trait — the biography may not exist ('when available') — but says nothing about auth requirements, empty-result shape, or whether it hits a remote source.

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, front-loaded sentence with zero filler. It is efficient, though so terse that it omits information the tool actually needs.

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?

An output schema exists, so return values need not be explained, and annotations cover the read-only profile. What is missing for a simple one-param tool is any guidance on argument sourcing and differentiation from the large set of sibling artist tools.

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 single parameter has 0% schema description coverage, so the description carries the burden and contributes nothing: it never explains that artist_id is a TIDAL artist identifier or where one obtains it. Only the parameter's name hints at its meaning.

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?

States a specific verb and resource: return the artist biography text. That is unambiguous on its own, but it does nothing to distinguish itself from the many other tidal_get_artist_* siblings (get_artist, get_artist_page, get_artist_image), so an agent still has to infer which one answers 'tell me about this artist'.

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 when-to-use or when-not-to-use guidance and no named alternative. The only usage signal is the implicit 'when available', which tells the agent the result may be absent but not when to prefer this over tidal_get_artist or tidal_get_artist_page.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a small amount of value by signaling pagination ('page through'), which aligns with the limit/offset params, but it discloses nothing about ordering, empty results, or result shape beyond what the output schema provides.

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 filler. It is efficient, though arguably under-specified for a tool with three params and many near-identical siblings.

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?

An output schema exists, so return values need not be explained, and the read-only annotation covers mutation risk. However, for a paginated list tool surrounded by many similar artist-catalog tools, the absence of any usage distinction or param context leaves the definition at minimum viable.

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 carry the burden for limit, offset, and artist_id, and it says nothing about any of them. The parameter names are largely self-explanatory, which prevents a 1, but the description adds no semantics (e.g., valid ID source, default page size) beyond the schema.

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?

States a specific verb ('page through') and resource ('an artist's EPs and singles'), which distinguishes it from siblings like tidal_get_artist_albums, tidal_get_artist_other_albums, and tidal_get_artist_top_tracks. It is clear what subset of an artist's catalog this returns, though it doesn't explicitly contrast itself against those siblings.

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 guidance on when to use this versus the many closely-named siblings (get_artist_albums, get_artist_other_albums, get_artist_top_tracks). The agent must infer the distinction purely from the tool name and the phrase 'EPs and singles'.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the result is a URL and that the size is square, which is modest extra context, but says nothing about missing-image behavior, URL expiry, or fallback sizes.

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 filler; the resource and the size semantics are both stated up front.

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 read-only lookup with an output schema, the description covers the essential behavior (returns a URL at a given square size). The gaps are minor: no note on what happens when no image exists and no artist_id guidance.

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. 'Square size' usefully clarifies that the dimensions parameter applies to both width and height rather than one axis, which is not stated in the schema. However, it says nothing about the artist_id parameter or the 80–3000 bounds and 750 default, so compensation is only partial.

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?

States a specific verb and resource ('Return an artist-image URL'), and the resource name distinguishes it from the many sibling image tools (album_image, playlist_image, video_image, mix_image). It doesn't explicitly differentiate itself from those siblings in prose, but the resource 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 guidance on when to use this tool versus alternatives (e.g. tidal_get_artist, tidal_get_artist_page, which likely also surface images) or any precondition such as needing a valid artist_id from a search. The agent must infer usage entirely.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a minor behavioral hint via 'Page through', which aligns with the limit/offset parameters, but it discloses nothing about auth needs, rate limits, or result ordering. With annotations carrying the safety burden, a 3 is appropriate.

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 efficient sentence with no filler, and the resource is front-loaded. It is appropriately short, though arguably too terse given the gaps it leaves unaddressed.

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?

Output schema exists, so return values needn't be explained, but the definition still leaves key gaps: no sibling differentiation, no explanation of the required artist_id, and no usage context. For a tool with 0% schema coverage and many look-alike siblings, this is under-specified.

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 three undocumented parameters (artist_id, limit, offset). It only loosely gestures at pagination with 'Page through' and never mentions which artist is being scoped or the meaning of the id. It adds little meaning beyond the schema field names.

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 gives a verb ('Page through') and a resource ('compilations and other album appearances'), which is somewhat specific. However, it never states that results are scoped to a single artist, and it does nothing to distinguish itself from close siblings like tidal_get_artist_albums or tidal_get_artist_ep_singles. The purpose is implied rather than sharp.

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 guidance on when to use this tool versus tidal_get_artist_albums, tidal_get_artist_ep_singles, or the other artist-scoped listers. No prerequisites (e.g., needing an artist_id) or exclusions are stated. The agent must infer usage entirely from the name.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it doesn't say what a 'page' payload contains, whether it is a composite layout response, or how it relates to the other artist endpoints. For a tool whose main ambiguity is its output shape, this is thin.

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 front-loaded sentence with no filler or redundancy. It is appropriately sized, though its brevity edges toward under-specification rather than efficiency.

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?

An output schema exists, so return values need not be spelled out, but the description still leaves the tool's core distinction from tidal_get_artist unresolved and gives no guidance on the required artist_id. For a 1-parameter, open-world read tool in a dense sibling cluster, it is not complete enough to route 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% and the single required parameter artist_id has no description in the schema or the description text. The description never mentions the ID, its expected format, or where to obtain it, so it fails to compensate for the coverage 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?

States a verb ('Return') and a resource ('the structured TIDAL page associated with an artist'), but the key term 'structured page' is never defined, leaving it unclear how this differs from tidal_get_artist or tidal_get_album_page. An agent cannot confidently tell what a 'page' object is versus the plain artist resource from this sentence 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?

There is no when-to-use guidance, no exclusion, and no reference to any of the many sibling tools that also return artist data (tidal_get_artist, tidal_get_artist_bio, tidal_get_artist_albums). The agent is left to infer the selection criteria entirely.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the description is not the primary source of behavioral facts. The phrase 'page through' hints at pagination, but the description adds no operational detail about ordering, rate limits, or what an empty result means, so it earns little beyond the annotations.

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 filler or redundancy. It is efficient, though its brevity borders on under-specification rather than being a model of dense, informative concision.

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 relieves the description of explaining return values, but with three parameters at 0% schema coverage and no differentiation from the radio_mix sibling, the definition is too thin for an agent to call it confidently. More is needed about paging and variant choice.

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 three undocumented parameters. It mentions 'for an artist' (loosely mapping to artist_id) but says nothing about limit or offset semantics, leaving the paging parameters entirely 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 gives a clear verb ('Page through') and resource ('radio tracks for an artist'), which is enough to separate it from most siblings like bio, albums, or top_tracks. However, it fails to distinguish itself from the very close sibling tidal_get_artist_radio_mix, leaving the agent to guess which 'artist radio' variant applies.

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 statement of when to use this tool versus alternatives such as tidal_get_artist_radio_mix or tidal_get_artist_top_tracks, nor any prerequisites or exclusions. 'Page through' vaguely implies list-style retrieval but no selection guidance is given.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the notion that the mix is 'reusable' and 'powers artist radio' — no auth requirements, rate limits, or behavioral traits beyond the 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.

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

A single efficient sentence with no filler and the key concept front-loaded. It is appropriately sized, though brevity here comes at the cost of the missing differentiation noted above.

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?

An output schema exists, so return values need not be explained, and annotations carry the safety profile. However, the description fails to disambiguate from tidal_get_artist_radio and provides no parameter guidance, leaving meaningful holes for such a crowded sibling set.

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 single required parameter artist_id has 0% schema description coverage, and the description says nothing about it — no format, no source (artist ID from search, or a TIDAL-specific ID?), no validation notes. The description does not compensate for the documentation 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?

States a verb ('Return') and a resource ('the reusable mix that powers artist radio'), which is more than a tautology, but the phrase is vague about what the returned object actually is (a mix entity? a radio seed?). Critically, it does not distinguish this tool from the near-identical sibling tidal_get_artist_radio, leaving the agent unable to tell them apart.

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 when-to-use guidance, no prerequisites, and no mention of any alternative. With siblings like tidal_get_artist_radio, tidal_get_track_radio_mix, tidal_get_mix and tidal_get_mix_v2 in the same namespace, the omission is a real routing hazard rather than a minor gap.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and external-lookup behavior are covered. The description adds the pagination behavior ('page through'), which is useful context, but says nothing about result ordering, similarity basis, or rate limits.

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

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

A single short sentence with the resource front-loaded and no wasted words. It is efficient, though the brevity comes partly at the cost of missing detail rather than from tight editing of richer content.

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?

An output schema exists, so return values need not be explained. However, for a read tool with three undocumented parameters and no usage guidance, the description is only minimally adequate 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 carries the full burden, yet it only vaguely implies an artist_id ('seed artist') and pagination ('page through'). It does not explain limit defaults/caps, offset semantics, or the artist_id format expected by the API.

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?

States a specific verb ('page through') and resource ('artists related to a seed artist'), which is enough to distinguish it from siblings like tidal_get_artist_albums or tidal_get_artist_top_tracks. It is clear but does not explicitly differentiate itself from nearby tools such as tidal_get_artist_radio or tidal_get_artist_radio_mix.

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 indication of when to use this versus the many other artist-related siblings (radio, mixes, top tracks, page). The word 'seed' implies an artist_id is required, but there is no explicit when/when-not guidance.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the pagination behaviour ('page through'), which is genuinely useful context, but says nothing about ranking basis, region/catalog dependence, or empty-result behaviour.

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 short, front-loaded sentence with no wasted wording. It is efficient, though the terseness is close to under-specification rather than deliberate concision.

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?

An output schema exists, so return values need not be described, and the schema covers limit/offset bounds. However, for a required-param, paginated list tool the definition omits what 'top' is ranked by and how the required artist_id is obtained, leaving gaps an agent must guess at.

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% for three parameters. 'Page through' gestures at limit/offset semantics but gives no default/bound context beyond what the schema already declares, and the required artist_id parameter is completely unaddressed (format, source, length constraints).

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 identifies the resource ('an artist's most prominent tracks') and implies a list/read operation, but 'most prominent' is a loose paraphrase of the tool name's 'top tracks' and the phrase 'page through' is vague about what is actually returned. It does not differentiate this from siblings like tidal_get_artist_radio, tidal_get_artist_albums, or tidal_get_artist_videos.

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 hint is the word 'page through', which suggests browsing rather than a one-shot fetch, but there is no statement of when to choose this over tidal_get_artist_radio, tidal_get_artist_similar, or the general search tools. No prerequisites (artist_id must resolve) are mentioned.

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?

Annotations already declare readOnlyHint and openWorldHint, covering the safety profile. The description adds the pagination behavior ('Page through'), which is useful context beyond annotations, but it does not disclose ordering, rate limits, or error 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?

A single, front-loaded sentence with no wasted words. It is appropriately concise, though its extreme brevity contributes to the completeness gap.

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?

Output schema exists and annotations cover safety, so return values need not be explained. However, for a three-parameter tool with 0% schema description coverage, the description is too thin: it should at least clarify artist_id format and limit/offset meaning.

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 carries the full burden. It mentions 'an artist's videos' (implying artist_id) and paging (implying limit/offset), but never names or explains any parameter, leaving limit and offset semantics 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?

States a specific action ('Page through') and resource ('artist's videos'), distinguishing it from single-video or generic browse tools by name. However, it does not explicitly differentiate from siblings like tidal_browse_videos or tidal_get_video, so it falls short of a 5.

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 when-to-use guidance, no alternatives named, and no prerequisites. An agent must infer that this is for a known artist ID and that it differs from tidal_browse_videos from the tool name alone.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The word 'exact' hints that these are authoritative totals rather than paginated estimates, which is genuinely useful, but nothing is said about authentication requirements, whose favorites are counted, or failure modes when unauthenticated.

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 tight sentence with the outcome front-loaded and no filler. Every word earns its place and there is nothing to trim.

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?

An output schema exists, so the description does not need to explain return values, and with no parameters and read-only annotations the surface is small. It is nearly complete, with only the implicit assumption that counts are scoped to the authenticated user left unstated.

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 takes zero parameters, so there is nothing for the description to clarify; the baseline for a no-parameter tool is 4. No misleading hints about inputs are present.

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 gives a specific verb ('Return') and a precise resource ('exact saved track, album, artist, playlist, and video counts'), enumerating all five favorite categories. This separates it from the many list_favorite_* siblings, which return items rather than aggregate numbers. It stops short of explicitly naming that alternative, so it is clear but not fully differentiated.

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?

Usage is implied rather than stated: an agent can infer this is the tool to call when only totals are needed instead of full lists. No when-not conditions, no named alternatives (e.g. 'use tidal_list_favorite_tracks if you need the items themselves'), and no note that it reflects the authenticated user's favorites. Minimum viable guidance.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one useful behavioral fact – that only 'public' metadata is returned – but says nothing about auth requirements or error behavior for invalid IDs.

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 tightly-scoped sentence with zero waste, front-loading the return action and the scope constraint.

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?

An output schema exists, so return values need not be explained, and a single required param keeps the call simple. However, with no usage guidance distinguishing it from the folder-listing siblings, the definition 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?

Schema coverage is 0%, so the description must carry the single param. It clarifies the ID is a playlist-folder identifier and that it is an exact-match lookup, which adds some meaning, but gives no format, length, or example beyond the schema's min/max length.

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?

States a specific verb ('Return') and resource ('playlist-folder metadata') scoped to a single exact ID. The word 'exact' implies single-item retrieval versus the sibling list tool, though it never names tidal_list_playlist_folders or tidal_list_folder_items explicitly.

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 when-to-use, prerequisites, or alternatives are given. The agent can infer it is used when a folder ID is already known, but nothing routes it away from tidal_list_playlist_folders or toward tidal_list_folder_items for content.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The word 'Page through' usefully signals paginated browsing, which aligns with the limit/offset params, but no additional behavioral detail (rate limits, auth needs, pagination bounds) is given. With annotation coverage this warrants a modest 3.

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 sentence, front-loaded with the verb and resource, with zero filler. It is efficient, though arguably too terse for the tool's parameter complexity rather than 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?

An output schema exists, so return values need no explanation, and annotations cover the safety profile. However, for a paginated, enum-driven browse tool, the missing genre_path format guidance and absent routing versus sibling genre/item tools leave the definition only marginally 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 must carry the load. It enumerates the `kind` values, which partially covers the enum, but the required `genre_path` format (name, slash-delimited path, or ID?) is unexplained, as are limit/offset semantics. For a 4-param tool with a required, format-ambiguous parameter, this 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?

States a clear verb-and-resource ('Page through tracks, albums, artists, playlists, or videos in one genre'), and the enumerated kinds match the `kind` enum. It is distinguishable from genre-listing siblings like tidal_list_genres, but it never names a sibling explicitly, so differentiation rests on the agent's own inference.

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 when-to-use or when-not-to-use guidance. The description does not explain how this differs from tidal_list_genres, tidal_browse_genres, or per-resource item tools like tidal_get_album_items, nor does it state prerequisites (e.g. that a valid genre_path must first come from a genre-listing 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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds only that the payload is 'public metadata' and that the ID is 'legacy', which is modest added context but no auth, rate-limit, or failure 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?

A single front-loaded sentence with no filler; the key scoping word 'legacy' arrives early. Nothing could be trimmed without losing 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?

An output schema exists so return values needn't be described, and the read-only annotations cover safety. What remains missing is the sibling disambiguation (legacy vs v2 mix) and any hint about the ID format, which leaves the agent under-informed for a tool with 0% schema description coverage.

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 carry the parameter. It tells the agent the value must be an exact legacy mix ID, but gives no format, prefix, or example, and the schema only constrains length to 1-160 characters.

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?

States a specific verb (return) and resource (metadata for one mix) and adds the scoping word 'legacy' that hints at the distinction from tidal_get_mix_v2. However, it never names the sibling, so an agent still has to infer which of the near-identical mix tools to pick.

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 'one exact legacy mix ID' implies you must already hold an ID rather than browse, but there is no explicit when-to-use, no when-not-to-use, and crucially no routing to tidal_get_mix_v2 or tidal_browse_mixes. Given how many mix siblings exist, this omission is significant.

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?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds the useful nuance that the returned URL is legacy-format and constrained to supported sizes, but says nothing about expiration of the URL or what 'legacy' implies behaviorally.

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 that states the return value and its size constraint with no filler. It is efficient, though extremely terse for a tool with an enum parameter.

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?

An output schema exists so return values need not be explained, and annotations cover safety. However, for a tool sitting next to both tidal_get_mix_v2_image and tidal_get_mix, the description omits the routing guidance and any mention of the three supported sizes, leaving meaningful gaps.

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% for two parameters, so the description carries the burden. It only alludes to the dimensions parameter via 'at a supported size' without listing the 320/640/1500 values, and gives no detail on mix_id format. Partial compensation, so a middling 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?

States a specific verb and resource ('Return a ... mix image URL'), and the word 'legacy' implicitly distinguishes it from the newer tidal_get_mix_v2_image sibling. It does not name that sibling explicitly, so the agent must infer the distinction from 'legacy' 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?

There is no statement of when to use this tool versus tidal_get_mix_v2_image or tidal_get_mix, nor any prerequisite such as authentication or mix availability. 'Legacy' hints at older mixes but leaves the selection decision entirely 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?

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds pagination behavior ('Page through') and the returned entity types (tracks and videos), but does not disclose auth needs, rate limits, or ordering, leaving moderate gaps.

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 that states the action and resource without any filler. 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?

With an output schema covering return values and annotations covering read-only/open-world behavior, the description only needs to explain purpose and parameters. It covers purpose, but omits parameter semantics and usage context, leaving it minimally adequate.

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% for all three parameters (mix_id, limit, offset). The description hints at a mix identifier and pagination but never names or explains any parameter, default, or range, so it does not compensate for the schema's lack of 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?

States a specific verb ('Page through') and resource ('tracks and videos in a TIDAL mix'), which separates it from tidal_get_mix (metadata) and tidal_get_playlist_tracks (playlist scope). It does not explicitly name alternatives, so it is clear but not fully sibling-differentiating.

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 the tool is for enumerating a mix's contents, but it gives no explicit when-to-use or when-not-to-use guidance and names no alternative sibling. Adequate implied usage only.

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