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

Annotations already declare the mutation profile (readOnly=false, destructive=false, openWorld=false). The description adds that it returns the node id and parameters, and flags the OpenPBR limitation, but says nothing about the need for commit_material_changes/undo_material_changes or whether adding a node mutates the live material.

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?

Short, but the phrasing is fragmented and the line wrapping plus the ambiguous 'd'une copie' force the reader to re-parse. The most important constraint (no OpenPBR) is buried at the end rather than front-loaded.

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 graph-mutating tool with zero schema descriptions, the definition leaves the meaning of 'material' and 'name' and the commit/undo workflow unexplained.

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

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

Schema coverage is 0%, so the description must compensate. It does this well for 'type' (lux constants such as SHADER_TYPE_SPOTS vs. type names like 'lux_spots'), but leaves 'material' and 'name' entirely unexplained, so a third of the parameters remain 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 verb and resource: adds a node to a material graph, and names the accepted type values. It does not explicitly distinguish itself from siblings like connect_material_nodes or remove_material_node, though the verb makes the difference inferable.

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?

Gives an explicit when-not rule: no OpenPBR constant should be used here, instead copy an OpenPBR_* material from the library. That is real routing guidance, though it does not cover when to add a node versus editing parameters directly.

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 establish this is a mutating, non-read-only operation. The description adds substantial context beyond that: duplicate=true creates a shared copy that can be edited without affecting the original, duplicate=false with a library material produces a solid red appearance in background rendering, and the operation is undoable via undo_material_changes.

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 front-loaded with the core action and then explains the duplicate behavior in a compact, structured way. It includes a useful version-specific caveat without excessive length.

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 output schema exists, the description does not need to explain return values. It covers the key behavioral risks of duplication and rendering, and the undo path, which is sufficient for an agent to call this mutation tool correctly.

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

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

Schema description coverage is 0%, so the description must compensate. It explains the duplicate parameter thoroughly and says material may come from the scene or library, but it does not clarify the format or identifier expected for material or the meaning of object_ids beyond 'pièces'.

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: 'Applique un matériau ... aux pièces object_ids', and clarifies the material can come from the scene or the library. It does not explicitly distinguish itself from sibling tools like set_material_parameter or add_material_node, so it falls just 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?

It gives clear guidance on when to use the duplicate option ('défaut, recommandé') and warns against applying library materials without a copy because they render red in background renders. It also points to undo_material_changes for reversal, but does not compare the tool against other material-editing 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=false and destructiveHint=false, so the safety profile is partly covered. The description adds the crucial non-obvious trait that the undo stack is flushed, i.e. the commit is irreversible, which an agent cannot infer from the annotations alone. It still doesn't say what happens to uncommitted changes on failure, but the core risk is disclosed.

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

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

Two short sentences, zero filler, with the state-mutating effect front-loaded and the timing constraint second. Every sentence carries distinct information.

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

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

For a zero-parameter tool with an output schema and annotations, the description covers what it does, its irreversible effect, and its ordering relative to reload_bridge. Only the failure/partial-commit behavior is unstated, which is a small residual 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 there is nothing for the description to disambiguate; baseline 4 applies. The empty schema plus the description's framing ('en cours' = current pending changes) makes it clear the tool operates on ambient state rather than on arguments.

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?

Names a specific action (committing pending material changes) and states its concrete side effect: the undo stack is emptied. That distinguishes it from the sibling undo_material_changes, which obviously does the opposite. It stops short of an explicit contrast statement, but the verb+resource+effect combination 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?

Gives a concrete trigger ('quand l'utilisateur valide le résultat') and an explicit ordering constraint relative to the sibling reload_bridge, which is exactly the kind of sequencing guidance an agent needs. It does not state when to avoid calling it, but the 'validate the result' condition implicitly excludes speculative calls.

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 a non-read-only but non-destructive mutation. The description adds important behavior: an existing connection on that parameter is replaced, which is not obvious from the annotations. It does not cover permissions or error behavior, but the output schema handles returns.

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

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

Two sentences, front-loaded with the core action, and no wasted wording. The replacement behavior is stated immediately after the main operation.

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 need not be described. However, with four required undocumented parameters, the description leaves material ambiguous and does not fully specify source/target ID semantics, so it is adequate but incomplete.

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

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

Schema description coverage is 0%, so the description must compensate. It clarifies that source_id and target_id are node IDs and gives examples of valid parameter values, but material remains completely unexplained and source/target ID formats are not specified.

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: connects source node output to a target parameter and replaces any existing connection on that parameter. It distinguishes the operation from a mere add or set, though it does not name sibling alternatives.

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

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

No explicit guidance on when to use this versus disconnect_material_input, add_material_node, or set_material_parameter. Usage is only implied by the operation itself and by the note that an existing connection is replaced.

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 declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the safety profile is partly given. However, for a mutation that removes a connection, the description says nothing about side effects, whether the disconnect persists without a commit, or required state; it adds almost no behavior 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 compact, front-loaded sentence with no filler. The only friction is that it is written in French while the rest of the tool surface is English, which slightly hurts scanability.

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 3-param mutation with 0% schema coverage and an output schema present, the description is too thin: it omits the `material` argument, side effects, and the commit/persistence requirement, leaving an agent underspecified to call it correctly.

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

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

Schema description coverage is 0%, so the description must carry parameter meaning. It documents two of the three required params (`node_id` and `parameter`) but omits `material` entirely, leaving a third of the required inputs unexplained in either place.

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 (disconnects) and the target resource (the `parameter` input of node `node_id`), so an agent can tell it apart from connect/add/remove node siblings. The reference to the containing material is only implicit ('d'une copie'), leaving the scope slightly soft, but the action is clear.

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

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

There is no guidance on when to use this versus siblings such as connect_material_nodes or remove_material_node, nor any prerequisites (e.g., connect/commit workflow). 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 destructiveHint=true and readOnly=false, so the description does not need to restate that writing Python mutates the scene. It adds genuinely new behavioral facts: the tool is disabled by default at the bridge level and requires a specific config opt-in, which the annotations do not convey. It stops short of describing execution scope, timeout, or what a refusal looks like, so it is strong but not exhaustive.

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?

Three short sentences ordered by importance: what it does, how it is gated, when to prefer alternatives. The inline JSON literal for the config key is slightly noisy but is the precise, actionable form an agent would need.

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 an arbitrary-code-execution tool with an output schema (so return values need no prose), the description covers purpose, safety posture via annotations, enablement gate, and sibling routing. The remaining gap is the execution environment itself — scope, available modules beyond 'lux', and failure behavior — which matters for a tool this powerful.

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 'code' parameter, so the description must compensate. It adds one useful hint — the 'lux' module is available in the execution context — but says nothing about what namespace the code runs against, whether it must return a value, or size limits. Partial compensation only.

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 concrete verb and resource ('Exécute du Python dans KeyShot') and immediately scopes it against the whole sibling set with 'Dernier recours, quand aucun outil dédié ne convient.' An agent can tell this apart from render_image, assign_material, etc. without opening any schema.

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

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

Gives an explicit when-to-use rule (last resort, only when no dedicated tool fits) and an explicit precondition that would otherwise cause a hard failure (bridge refuses unless pont-config.json has execute_python: true). This is exactly the routing and gating information an agent needs before calling.

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?

Beyond the annotations it discloses two non-obvious traits: existing cameras are not modified, and the call is rejected unless the current view is saved, with force=true discarding that view. The data-loss warning on force=true is exactly the kind of context annotations cannot express, though it does not state what the response contains or how failure is reported.

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?

Front-loaded with the core action, then the safety constraint, then the alternative — a sensible ordering with no filler. It is dense but every clause carries information; only the 'la vue est perdue' parenthetical slightly duplicates the preceding refusal clause.

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 description covers the mutation, its side effects, and the prerequisite for node ids. Minor gaps: no guidance on behavior with an invalid node_id, and the units/semantics of `margin` are left to inference.

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

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

With 0% schema description coverage the description carries the burden and mostly does: `name`, `node_id` (valid ids from get_scene_tree detail=true), `margin` (how far to back off), and `force` (only with user consent) are all explained. The exact meaning of `margin` (multiplier vs. absolute distance) and its default of 1.15 remains implicit.

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?

Names a specific verb and resource ('Crée une caméra neuve') and states the exact framing target ('cadrée sur le nœud `node_id`'), the margin behavior, and that the result is saved. It also distinguishes itself from the sibling `set_camera` by noting existing cameras are untouched, so an agent can pick correctly without opening schemas.

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?

Explicitly recommends itself over 'un changement de cadrage manuel', states the preconditions for refusal (current view unsaved), and prescribes when the override applies ('force=true seulement avec l'accord de l'utilisateur'). It also points to `get_scene_tree detail=true` as the source of valid node ids.

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 state readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds meaningful behavior not in annotations: the editable flag only applies to bridge-created copies, and color values are read in linear 0-1 space.

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 front-loaded with the return structure and then supplies useful type-code context. It is dense but efficient, with no wasted sentences.

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, but the description still usefully explains the graph shape, editable semantics, and type mappings. The main remaining gap is that the input material parameter is not described, so an agent may know what comes back but not exactly how to request it.

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 sole material parameter. The description says it retrieves a scene material's graph but does not explain how to identify the material, such as by name, id, or path, so it does not compensate for the missing schema documentation.

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

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

The description names a specific resource, the graph of a scene material, and details the returned nodes, parameters, and input_from links. It is clearly distinct from list_materials and material-editing siblings because it describes a single material's graph structure.

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 only implied: the editable flag and the note that only bridge-created copies can be edited in the graph suggest this tool is for inspecting editable material graphs. There is no explicit guidance on when to call it versus list_materials or set_material_parameter.

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=false, so the safety profile is covered. The description adds a little by listing the exact facts returned (counts, unit, resolutions), which signals this is a summary read rather than a deep traversal, but it says nothing about cost, latency, or whether the scene must be loaded.

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 compact sentence that front-loads the most identifying facts (name and file) before the counters and settings. Nothing is padded, though the enumerated field list is partially redundant with the output schema.

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 present and zero parameters, the description does not need to explain return values, so its coverage is adequate but minimal. It leaves the reader without guidance on how this differs from other scene-inspection siblings or what environment it requires.

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 to disambiguate and the description correctly introduces no argument semantics. Baseline 4 applies for a parameterless 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?

The description names the resource and enumerates exactly what the call surfaces: scene name/file, object and triangle counts, unit, and view/render resolutions. An agent can tell it is a lightweight scene-metadata read. It does not, however, distinguish itself from nearby siblings such as get_scene_tree, list_objects, or keyshot_status, which plausibly overlap.

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 only implied: an agent can infer this is the cheap 'what scene am I in' call, but the text never says when to prefer it over get_scene_tree or keyshot_status, nor does it state any prerequisite such as an active bridge connection. No exclusions or alternatives are offered.

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, so the safety profile is covered. The description adds genuinely non-obvious context: piece, material and camera names originate from third-party CAD files and are data, never instructions — an explicit prompt-injection warning that an agent would otherwise not have. It does not, however, disclose truncation behaviour implied by max_chars/max_nodes.

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

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

Two front-loaded sentences: mode behaviour first, data-provenance caution second. No filler, and the injection warning earns its place. Slightly dense due to the mode branching being packed into one sentence.

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 readOnlyHint and an output schema present, much of the burden is already lifted, and the mode explanation plus provenance warning cover the core. The gap is the undocumented size limits (max_chars, max_nodes) on a tool whose output can be large, which an agent needs to call it correctly.

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

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

Schema description coverage is 0%, so the description must carry all parameter meaning. It explains detail thoroughly across both values, but max_chars and max_nodes — the two controls that determine whether the returned tree is complete or truncated — are never mentioned anywhere, leaving the agent unable to reason about output size.

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

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

The description states the resource (scene tree) and precisely splits behaviour by mode: detail=false returns the raw KeyShot text dump, detail=true returns the first nodes with id, type and material. That is concrete and lets an agent predict what it gets. It falls short of 5 because it never distinguishes itself from siblings like list_objects or get_scene_info.

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

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

The two-mode behaviour implies when to pick detail=true vs detail=false, but the choice is never framed as a recommendation. There is no guidance on when to prefer this tool over list_objects, get_scene_info or list_materials, which overlap substantially.

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=false, so safety is covered. The description adds that this probes both the bridge layer and the application layer, which is useful beyond the annotations, but an output schema exists and the enumerated facets largely restate what that schema returns.

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 compact sentence plus the ordering directive, with the resource named first and the call-order instruction last where it is most salient. No filler.

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 present and no parameters, the description need not explain return values, and it correctly positions itself as the entry-point probe. Only minor gap: it doesn't characterize cost or what an agent should do if the bridge reports as down.

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

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

The schema takes zero parameters, so there is nothing parameter-level to disambiguate; the baseline for a no-param tool applies. The description correctly implies a parameterless probe but adds no further semantic detail, which is acceptable 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?

Names a specific resource (bridge + KeyShot state) and enumerates the concrete facets reported: versions, whether a scene is open, realtime pause state, active renders, available commands. That sets it apart from narrower siblings like render_status or get_scene_info, though it never explicitly says how it relates to them.

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?

'À appeler en premier' gives an explicit, actionable ordering directive that an agent can follow immediately. It stops short of stating when not to call it (e.g. once state is already known) or which sibling supersedes it for a narrower question.

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=false, so safety of the call is covered; the description adds real value by explaining what unsaved_changes means and by warning that CAD-derived part/material/camera names are data, not instructions (a prompt-injection guard). It stops short of describing anything about list size, ordering, or behavior on empty scenes.

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

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

Two sentences, front-loaded with the payload contents before the data-provenance caveat; nothing is redundant. The first sentence is a bare noun phrase rather than a complete statement of action, which slightly weakens the opening.

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

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

For a zero-parameter read tool with an output schema and read-only annotations, the description covers what comes back and the injection-safety concern. It does not establish the workflow relationship to set_camera/fit_camera (e.g., that names from this list feed set_camera), leaving the agent to infer how this tool fits into camera operations.

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 has nothing to explain and the baseline of 4 applies. The description correctly introduces no parameter concepts that would need further clarification.

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 the exact resource set returned: scene cameras, the active camera, and an unsaved_changes flag, which lets an agent distinguish it from mutation siblings like set_camera or fit_camera. It lacks an explicit verb ("Lists...") and never explicitly contrasts itself with those siblings, keeping it below 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?

There is no when-to-use or when-not-to-use guidance and no named alternative, even though set_camera and fit_camera are obvious siblings an agent must choose between. Usage is only inferable from the tool name and the noun phrase describing the payload.

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=false, and an output schema exists, so safety and return shape are covered elsewhere. The description adds nothing beyond the noun phrase — no note on ordering, whether it includes default/library environments, or what 'active' means.

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?

It is very short and front-loaded, but it is an under-specified sentence fragment in a different language than the other descriptions, which may cost an agent clarity. Brevity here reflects a thin description rather than tight writing.

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

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

For a zero-parameter read-only lister with annotations and a full output schema, the description is minimally sufficient to identify the resource. It stops short of telling the agent how this pairs with set_environment when it wants to change the active environment.

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; baseline 4 applies. The fragment does at least scope the returned content (scene environments plus the active one).

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 text "Environnements de la scène et environnement actif" is a noun phrase that largely restates the tool name list_environments rather than stating a verb+resource action. It does hint that the result includes the active environment, which is slightly more than the name alone, but an agent gets no explicit 'lists all environments' framing.

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 mention of the sibling set_environment, and no stated prerequisites. Only implicit, weak inference (this reads, set_environment writes) links it to 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 cover the safety profile (readOnlyHint true, openWorldHint false), yet the description adds the non-obvious operational trait that the first call of a session loads the library and takes several seconds, plus that query matching is server-side and case-insensitive. That is real added context beyond structured fields, though nothing is said about how 'limit' truncates the ~1 000 results.

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?

Front-loaded with the resource and cardinality, then each parameter's semantics, then the one-time latency warning. Every sentence contributes a distinct, actionable fact with no filler.

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 the latency and filtering behaviors are covered. The only missing piece an agent would want is what 'limit' does relative to the ~1 000-item library.

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 carries the full burden and mostly delivers: it explains that 'filter' is a library folder that must be prefixed with 'Materials/' (with concrete examples) and that omitting the prefix yields zero results, and that 'query' is a case-insensitive server-side substring match. The third parameter, 'limit' (default 300), is never mentioned, leaving a 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 specific verb and resource ('Matériaux de la bibliothèque KeyShot') and even the corpus size (~1 000 items), so the agent knows this enumerates the stock library rather than scene materials. It never names its closest sibling (list_materials), so the distinction from scene-level material listing must be inferred from the word 'bibliothèque'.

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 the filter semantics ('Materials/Metal', 'Materials/Plastic'), which tell the agent the intended browsing pattern, and the warning that an unprefixed filter returns nothing is a genuine usage constraint. However, there is no explicit when-to-use/when-not statement versus list_materials or get_material.

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=false. The description adds a meaningful safety behavior not present in annotations: names from third-party CAD files are data, never instructions, which warns the agent about prompt-injection risk.

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

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

The description is two short sentences with no wasted text. The purpose statement comes first, followed by an important security caveat.

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 parameterless, read-only listing tool with an output schema and safety annotations, the description is mostly complete. It clarifies scene scope and warns about untrusted CAD names, though it still omits explicit routing guidance versus sibling material-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?

The tool has zero parameters and an empty input schema, so there are no parameter semantics for the description to clarify. The baseline score for 0 parameters is 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?

The description identifies the resource and scope ('Matériaux appliqués dans la scène'), which distinguishes it from library-material tools such as list_library_materials. However, it is a noun fragment with no explicit verb, so the action of listing is inferred from the tool name rather than stated in the description.

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

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

The description provides no guidance on when to use this tool versus alternatives like get_material or list_library_materials. It also does not mention prerequisites, exclusions, or typical invocation contexts.

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 closed-world, so safety of the read is covered. The description adds genuinely new context: the prompt-injection warning that CAD-derived names are data and never instructions, plus what bbox returns (world-coordinate bounding box). It does not discuss ordering or pagination for large scenes.

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?

Front-loaded with the resource and return fields, then parameter guidance, then the data-safety note. Slightly sprawling across line breaks, but each sentence (including the injection warning) carries real 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 an output schema present, the return-value burden is off the description, yet it still names key fields. For a two-optional-parameter read tool it covers purpose, both parameters, and a security caveat; only cross-tool routing guidance is missing.

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

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

Schema description coverage is 0%, so the description carries the full burden and largely succeeds: it defines material as a filter on scene parts and bbox=true as returning a world-coordinate bounding box with a concrete use case. Default behavior (bbox=false) and material matching rules (exact vs. substring) are left unstated.

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 the resource clearly (scene parts) and enumerates the returned fields (id, chemin, matériau), so the agent knows this is a parts/objects listing. It does not explicitly contrast with siblings like get_scene_tree or list_materials, so it stops 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?

Usage is only implied: the bbox explanation hints at when that flag is useful ('pour reconnaître une pièce par sa taille ou sa position'), and material implies filtering. But there is no explicit statement of when to choose this tool over get_scene_tree or get_scene_info.

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=false, so safety is covered. The description adds real value beyond that: data is read from the running KeyShot instance (implying KeyShot must be live), and detail=true expands to full docs plus class methods.

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?

Three short sentences with the core purpose first, then the detail flag, then the use case. No filler; only mild terseness in the module mention.

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 two of three parameters are covered in prose. What remains underspecified is what 'query' accepts (signature? name? wildcard?), which matters for a lookup 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 carry parameter meaning; it explains module ('lux' or 'luxmath') and detail=true (full documentation and class methods). The primary 'query' parameter is never explained, 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 clear verb-resource pair: introspecting the KeyShot scripting API (functions, classes, constants) from the live 'lux'/'luxmath' modules. It is distinguishable from execute_python by framing itself as a signature-lookup tool, though it never names the 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?

The final sentence ('Sert à vérifier une signature avant de s'en servir') gives a concrete use condition: consult before calling an API. No explicit when-not or named alternative, but the intended context relative to script execution is clear.

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?

Les annotations indiquent déjà readOnlyHint=false et destructiveHint=false ; la description ajoute deux éléments non structurés : le rechargement se fait sans « Run » de l'utilisateur (l'agent déclenche directement) et l'appel est refusé si des modifications de matériau sont en attente. Aucune mention en revanche de l'impact d'un rechargement sur l'état courant du pont ou de la scène.

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?

Deux phrases denses, sans remplissage : la mécanique du rechargement est en tête, la contrainte bloquante ensuite. Chaque proposition apporte une information exploitable pour l'appel.

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?

Pour un outil sans paramètre, annoté et doté d'un output schema (le format de retour n'a donc pas à être décrit), la définition couvre l'essentiel : déclenchement, origine du fichier, condition de refus. Il manque uniquement les conséquences du rechargement sur l'état existant du pont.

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?

Aucun paramètre (0 requis, couverture 100%) : le socle de 4 s'applique, la description n'ayant aucun argument à documenter ni à contredire.

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?

« Recharge le pont depuis son fichier dans le dossier Scripts de KeyShot » énonce un verbe et une ressource précis, avec l'origine du fichier rechargé. Le terme « pont » reste toutefois propre au domaine et n'est pas défini, ce qui empêche une distinction totalement autonome vis-à-vis d'outils comme execute_python ou les outils matériaux.

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?

Le contexte d'emploi est donné (« après une mise à jour ») et la précondition d'échec est explicite : refusé tant que les changements de matériau ne sont pas annulés ou gardés, avec les deux outils alternatifs nommés (commit_material_changes et son pendant undo_material_changes listé en sibling). Il manque seulement une indication de quand préférer reload_bridge à une autre voie (par ex. relancer l'application).

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

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

The description says the tool deletes/removes a node and its connections, which is a destructive mutation, while the annotations declare destructiveHint=false. This directly contradicts the behavioral signal in the annotations, even though the description usefully adds that root nodes are protected and branchings are also removed.

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 appropriately concise, though the phrase 'branchements' is slightly ambiguous without further context.

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 destructive mutation tool with an output schema and 0% parameter description coverage, the description is incomplete. It does not explain parameter meanings, required material context, or whether changes must be committed, and its deletion behavior conflicts with the non-destructive annotation.

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

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

Schema description coverage is 0%, so the description must explain the two parameters. It does not clarify what 'material' refers to, nor does it define the expected value for 'node_id'; it only generically mentions a node and a copy.

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

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

The description clearly states a specific verb and resource: removing a node from a graph copy and its branchings. It also adds an important scope constraint that the root cannot be removed, though it does not explicitly name the material graph context.

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

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

The description provides one clear usage boundary — the root node is excluded — but it does not explain when to use this tool versus siblings such as disconnect_material_input or undo_material_changes. Usage is implied rather than explicitly guided.

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

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

The annotations already declare this is a non-read-only, non-destructive, non-open-world operation, so the description does not need to carry the full safety burden. It adds a useful behavioral constraint that the target is a copy created by the bridge, but it does not explain permissions, reversibility, or side effects beyond that.

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

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

The description is a single short sentence with no structural waste, but it is too terse for a mutation tool with two required parameters. The brevity reflects under-specification rather than appropriately sized 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?

Although an output schema exists and annotations cover basic safety, the description does not give enough context to confidently select this tool among many sibling material tools. The meaning of "copie créée par le pont" is left unexplained, and the required parameters are not clarified.

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 two undocumented parameters. It vaguely implies renaming a copy, but never identifies the material parameter, the new_name parameter, accepted formats, or constraints. This is far from sufficient parameter 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?

The description gives a specific verb, "Renomme" (renames), and an object, "une copie créée par le pont" (a copy created by the bridge). However, it does not explicitly say this is a material copy and does not distinguish the tool from sibling material operations such as assign_material or set_material_parameter. The purpose is therefore understandable but vague.

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

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

The description provides no guidance on when to use this tool, when not to use it, or which sibling tool is the alternative. It only states the action and leaves all selection context to the agent.

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?

Goes well beyond the annotations: async non-blocking behavior, immediate job_id return, the caveat that max_time_s is indicative and scene prep adds overhead with a concrete 10s→80s example at 2560×2560, and the single-render-at-a-time limit. This is exactly the kind of behavioral context annotations cannot carry.

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?

Dense and front-loaded: purpose and async contract come first, then parameter notes, then the wait_for_render handoff and the material-change warning. Nearly every sentence earns its place, though the parameter notes are compressed into a run-on block.

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 present, the description needn't explain the return beyond noting job_id, and it covers the critical async/caveat behavior. The remaining gap is the undocumented overwrite and max_samples parameters, which matter for a tool that writes files.

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 does well for path (absolute, accepted extensions, default output folder), width/height (defaults to scene render resolution), and max_time_s (indicative semantics), but leaves overwrite and max_samples completely 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 specific verb+resource ('Lance un rendu') and immediately clarifies it is always asynchronous and returns a job_id right away. This distinguishes it cleanly from wait_for_render, render_status, and screenshot, which are adjacent 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?

Gives explicit routing ('Puis wait_for_render'), a hard concurrency constraint ('Un seul rendu à la fois'), and a usage prohibition ('Ne pas changer de matériau pendant un rendu'). The agent knows both what to do after and what not to do during.

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 closed-world, so the safety profile is covered. The description adds a genuinely useful behavioral criterion — a render is done when its file stops growing — which is not in any structured field. It omits, however, whether omitting job_id returns all jobs or errors.

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

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

Two short sentences, no filler, with the status vocabulary up front. It is terse almost to a fault, but nothing is wasted.

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 completion heuristic is covered. The unresolved optional-job_id behavior leaves an agent unsure whether this is a single-job query or a listing 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% and the single parameter job_id is never mentioned in the description, so the agent gets no guidance on what it identifies or what omitting it does. This is a real gap the description should have closed.

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?

Names the resource (render) and its status states (en_cours, termine, expire), so the agent knows this reports render progress rather than triggering one. It does not distinguish itself from the sibling wait_for_render, which covers adjacent ground.

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 poll this versus using wait_for_render or render_image, and no mention of what happens when job_id is omitted (list all renders vs. a single job). Usage must be inferred 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=false and destructiveHint=false, but the description adds real behavioral context: the collision refusal, the overwrite exception gated on user approval, and the fact that the response echoes the CMF as KeyShot stored it. Only the response shape beyond the CMF echo is left to the output schema.

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

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

The primary action and destination path are front-loaded, then constraints follow. It is dense and semicolon-heavy but every clause carries actionable information; no padding sentences.

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 mutation tool with an output schema already documenting returns and annotations covering the safety profile, the description supplies the missing pieces: collision handling, overwrite consent, path restrictions, and naming prerequisite. Adequate without redundant return-value explanation.

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

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

Schema coverage is 0%, so the description must compensate and largely does: it documents cmf with a concrete field example, restricts folder to a relative subfolder without "..", and gates overwrite behind user consent. The material parameter's own semantics (identifier vs. name) are only indirectly implied via the rename_material note.

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: saves a bridge-created copy into the KeyShot material library under Materials/<folder>/ so it can be reused in other scenes. This is clearly distinguishable from siblings like list_library_materials or assign_material, and the destination path is spelled out.

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?

Explicitly routes the agent to rename_material first ("Nommer d'abord la copie") and states the refusal condition when the material already exists, plus the exception overwrite=true only with user consent. Both when-to-use and when-not-to-use are covered with an alternative 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 destructiveHint=true, and the description adds real context beyond them: the previous version is copied into <dossier_sorties>/sauvegardes before overwrite, giving a recoverability story. It does not state the effect on a never-saved scene or whether backup can be suppressed, but the risk profile is well communicated.

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

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

Two short sentences, zero filler, with the destination default stated first and the destructive warning second. Every clause earns its place.

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

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

For a destructive two-parameter mutation with an output schema available for return values, the description covers the target file, the backup side effect and the permission threshold. The only meaningful gap is the un-documented 'backup' toggle and behaviour on a never-saved scene.

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 parameters and only partially does: it explains the default target file (clarifying that 'path' is optional) and describes the backup copy behaviour, but never ties that behaviour to the 'backup' boolean or says that setting it false disables the safety copy.

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 ('Enregistre la scène') plus the default destination ('par défaut sur son fichier .bip actuel'), so an agent knows exactly what is written and where. It does not explicitly distinguish itself from neighbours like save_material_to_library, but the scene-vs-material scoping 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?

Gives a hard usage constraint: overwriting the user's file is permitted 'seulement à sa demande explicite', which is exactly the gating condition an agent needs before invoking a destructive save. No alternative tools are named, which keeps it out of 5 territory.

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

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

The description discloses useful behavior: save=true writes a timestamped copy into <output_folder>/captures, and paused views yield a stale frame. However, this write-to-disk side effect is enabled by default while annotations declare readOnlyHint=true, which would lead an agent to assume no side effects occur. The behavioral detail is good but conflicts with the declared safety profile.

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

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

Three short clauses with the core action front-loaded, followed by the save semantics and the paused-state caveat in priority order. Efficient, with no filler, though the embedded references to other tools make it slightly dense.

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?

No output schema exists, so the description must carry the return contract, but it only says the view is 'rendered as image' without stating whether an image payload, a file path, or a reference is returned. The paused-view behavior is covered, but the return shape remains ambiguous.

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 is a single parameter with 0% schema description coverage, and the description fully compensates by defining what save=true does (timestamped copy retained in the captures folder). The default value's consequence is therefore inferable, which is more than the bare schema provides.

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: capturing the live KeyShot real-time view rendered as an image. It is distinguishable from render_image (a full render) and view_image, though it never names those siblings explicitly to sharpen the contrast. The scope is clear enough for an agent to select it correctly.

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?

Explicitly handles the main edge case: if the view is paused, the capture shows the last computed frame, and the agent is routed to keyshot_status (paused) and set_realtime. What's missing is guidance on when to choose this over render_image/view_image, but the conditional usage context is well above average.

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 only say it is a non-read-only, non-open-world, non-destructive operation; the description adds the crucial behavioral facts: the call is rejected when the current view has unsaved changes, those changes would be lost, and there is a known KeyShot quirk where a just-saved camera is flagged as modified. That is substantive disclosure 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?

Three short sentences: the action first, then the refusal condition, then the caveat about force. Nothing is padding and the most decision-relevant constraint (data loss) is surfaced early.

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 present, return values need no explanation, and the mutation's safety/authorization behavior is well covered. The remaining gap is the exact semantics of the 'name' argument (exact match, case sensitivity, source list), which would be needed for reliable invocation.

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

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

Schema coverage is 0%, so the description must carry the parameters, and it does explain force thoroughly: default false, refusal semantics, and the safe case. The required 'name' parameter is only implied by 'caméra enregistrée' — matching rules or whether it must equal a list_cameras entry are not spelled out.

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 first sentence gives a specific verb and resource ('Active une caméra enregistrée'), which clearly distinguishes it from list_cameras (enumeration) and fit_camera (creation). It does not explicitly state the contrast with those siblings up front, but the purpose is unambiguous.

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

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

It states exactly when the call is refused, what the agent should do instead (ask the user to save), and the only condition under which force=true is acceptable (with user consent, or for cameras created by fit_camera). This is explicit when/when-not guidance with an alternative path.

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=false and openWorldHint=false, so safety is covered. The description adds nothing beyond them: it does not say whether activation persists, whether the previous environment is replaced, or whether a render update is triggered.

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, but its brevity comes at the cost of under-specification rather than efficiency. It is front-loaded logically but starved of 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 described, but the definition still omits how to obtain a valid environment name, the effect of activation on the current scene, and the language mismatch (French description among English siblings) that may confuse matching. Not 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?

There is one required parameter with 0% schema description coverage; 'name' is bare in the schema and the description never clarifies that it must be an existing environment identifier (e.g. from list_environments). With low coverage, the description should compensate and it does not.

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

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

States a verb ('Active') and a resource ('un environnement de la scène'), so the operation is inferable, but it never explains what an environment is in this scene context or how it differs from sibling setters like set_camera or set_realtime. The agent must guess at the tool's effect.

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 prerequisite, and no reference to list_environments, the obvious companion tool for discovering valid values. Usage is only implied by the name and the single required argument.

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 mutating, non-readOnly, non-destructive, but the description adds non-obvious behavior: sRGB hex values are auto-converted to linear, alpha is preserved, and modifying a shared original affects multiple parts. It doesn't cover error/failure behavior (invalid parameter names, wrong node), which keeps it at 4 rather than 5.

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?

Front-loaded with the verb+resource, then node guidance, value formats, and cautions in a logical order. Dense with parenthetical detail, but every clause (conversion rule, matrix shape, copy warning) earns its place given zero schema coverage.

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, and annotations cover the safety profile. Format specs, undo path, node default, and shared-material risk are all present; only the identifier semantics for material/parameter remain thin for a mutation 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 coverage is 0%, so the description carries the burden. It richly documents value (color linear 0-1 vs #RRGGBB sRGB conversion, alpha preservation, matrix object shape with scale/rotate/translate) and states node_id defaults to root, but material and parameter are only implicitly defined — no format or naming convention is given for them.

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 ('Règle un paramètre d'un nœud du matériau') and distinguishes itself from siblings by naming get_material for parameter discovery and assign_material for copies. An agent knows exactly what operation this performs versus add_material_node or connect_material_nodes.

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?

Gives explicit conditional guidance: root node by default but useful params are often on the shader node (see get_material), undoable via undo_material_changes, and on shared originals use assign_material to a copy instead. Both the when and the when-not, plus the recovery path, are spelled out.

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

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

Annotations only declare the safety profile (not read-only, not destructive, closed-world); the description adds genuine behavioral context beyond that — this acts as a toggle and the view auto-restarts after renders when it was running before. That is non-obvious state behavior the annotations do not convey.

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

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

Two tight sentences, with the core action front-loaded before the auto-restart caveat. Nothing is padded, though the parenthetical UI reference is only marginally useful to an agent.

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 present, return values need no explanation, and the safety profile comes from annotations. For a single-boolean toggle the description covers the essential behavior; only the boolean polarity is left implicit.

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

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

Schema description coverage is 0% for the single required `paused` boolean. The description's 'met en pause ou relance' frames the toggle semantics, letting an agent infer true = pause, but it never states the mapping or the default state explicitly.

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 action (pause or resume) on a specific resource (the real-time view), and anchors it to a concrete UI control (the 'Pause' toolbar button). An agent can tell this apart from render/image siblings without opening the schema, though it never explicitly contrasts itself with any of them.

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 second sentence supplies real usage context: the bridge re-enables real-time view on its own after renders if it was previously running, so an agent knows it need not call this to restore the view after a render. There is no explicit statement of when-not-to-call or a named alternative, keeping it short of a 5.

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 and destructiveHint=false; the description adds the missing 'why' — the operation returns each object's prior state so the change can be reverted, which is the key safety fact for a mutating tool. It stops short of stating permissions, batching limits, or what happens to IDs that don't exist.

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

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

Two short sentences, front-loaded with the action and the parameter mapping before the revert behavior. No filler or repetition of the tool name beyond what is needed to define 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?

For a two-parameter mutating tool with an output schema and clear annotations this covers the essentials, but the description is in French while the tool names and parameters are English, and the term 'pièces' is never tied to the 'object' vocabulary used by siblings like list_objects and get_scene_tree, leaving a small but real gap in matching mental models.

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 meaning, and it does: 'visible=true' is explicitly tied to the boolean parameter and object_ids is sourced from list_objects. Both of the two parameters gain semantics the bare schema lacks.

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 pair with the boolean mapping inline (montre = visible=true, masque = visible=false) against a named resource (pièces). The pointer to list_objects for obtaining IDs makes the scope concrete. It does not contrast with any sibling, but the action itself 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?

Usage is implied: call it to show or hide parts, and fetch IDs via list_objects first. There is no explicit 'when not to use' or alternative route, and no note on whether visibility is per-scene, per-camera or global, so the agent must infer the context.

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

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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false; the description adds real context beyond them: the reversibility scope (materials/parameters only), the recency ordering, and the reassurance that non-undoable graph edits touch only copies. It does not mention whether there is any redo path or how far back the history goes.

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

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

Two sentences, zero filler, with the core behavior and the parameter semantics front-loaded before the scope caveat. Every clause carries 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 (return values need no explanation) and annotations cover the safety profile, so the remaining burden is scope and parameter meaning, both addressed. A minor gap: no note on how much history is retained or whether the undo can itself be reverted.

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% (the `all` boolean has no description), so the description carries the load and does it well: `all=false` means only the most recent change is reverted, implying `all=true` reverts all. One sentence fully disambiguates the only parameter.

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

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

States a specific verb (undo) applied to a specific resource (materials assigned and parameters set by the bridge), plus the ordering (most recent first). It also explicitly bounds the scope by excluding graph editing (nodes, connections), which separates it cleanly from siblings like add_material_node or connect_material_nodes.

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?

Explains the two use modes via `all` (undo everything vs. only the last change) and states a clear when-not: graph edits are not undoable, so the agent should not call this expecting to revert node/branch changes. It stops short of naming an alternative tool for that case, which keeps it from a 5.

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=false, so safety is covered. The description adds genuine context beyond that: it only reads local files, accepts only .png/.jpg, and caps at 16 MB, which is useful operational constraint disclosure.

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 compact sentence that front-loads the action and appends the format/size constraints. Nothing is wasted.

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 read-only, single-parameter tool with no output schema, the description covers purpose, formats, and size limit. The remaining gap is path format/form resolution, a minor omission given the low complexity.

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

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

Schema coverage is 0% and the single 'path' parameter is undocumented in the schema. The description partially compensates by implying the path points to a local .png/.jpg under 16 MB, but it doesn't specify absolute vs. relative path format or resolution of the path.

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 ('Montre une image locale') and clarifies the object with examples ('un rendu terminé, une capture') plus format/size constraints. It is clear what the tool does, but it doesn't explicitly distinguish it from the sibling 'screenshot' tool, leaving ambiguity about which 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?

Usage is implied by the examples ('a finished render, a screenshot'), suggesting you point it at an existing local file. However, there is no explicit when-to-use or when-not guidance, and no mention of choosing this over the 'screenshot' sibling.

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

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

The description adds useful behavior beyond the annotations by disclosing that it polls every 2 seconds and returns the final state. It does not explain timeout behavior, which matters because timeout_s defaults to 600, so an agent cannot tell what happens if the render does not finish in time.

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. The parenthetical polling interval is compact and directly relevant.

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

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

The output schema covers return values and the annotations cover read-only safety, so those do not need repeating. Still, for a blocking wait tool with an undocumented timeout parameter and no schema descriptions, the description should explain timeout semantics and job_id expectations to be fully complete.

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

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

Schema description coverage is 0%, so the description needs to compensate for both parameters. It does not explain what job_id refers to or what timeout_s controls, leaving the schema's bare titles as the only parameter information.

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: waits for the end of a render and returns its final state. The polling detail distinguishes it implicitly from a one-shot status check, but it does not name render_status as the sibling alternative.

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 polling behavior implies this is the blocking variant to use when the caller wants to wait until completion, suggesting render_status for non-blocking checks. However, that distinction is left implicit and no explicit when-to-use or when-not-to-use guidance is given.

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