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

No annotations are provided, so the description carries the full behavioral burden. It discloses the exclusive single-writer nature of the seat, but omits critical behavior for a lock-acquisition tool: what happens if the seat is already held, whether acquisition blocks or fails, auth requirements, and lease renewal/release semantics.

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

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

The description is a single, front-loaded sentence with no wasted words. It efficiently communicates the core action and scope.

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 purpose is adequately stated and the schema fully documents parameters, but with no annotations and no output schema, the description could do more to explain acquisition semantics such as conflict handling and lease behavior. It is minimally viable but leaves notable behavioral gaps.

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

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

Schema description coverage is 100%, so all four parameters are already documented in the input schema. The description adds no additional meaning about parameter formats or constraints beyond the examples already present in the schema.

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

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

The description states a specific verb ('Acquire'), resource ('execution seat'), and key scope ('exclusive single-writer', domain examples). It is clear what the tool does, but it does not explicitly differentiate itself from siblings such as release_seat or execute_domain_command.

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

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

There is no explicit guidance about when to use this tool versus alternatives like release_seat or execute_domain_command. The purpose implies claiming a seat before execution, but no conditions, prerequisites, or exclusions are stated.

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

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

With no annotations, the description carries the full behavioral burden. It discloses that a permission validation gate exists, which is genuinely useful, but says nothing about what happens on rejection, whether execution is sandboxed or destructive, timeout limits, or side effects. For a terminal-command execution tool this is a serious transparency gap.

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

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

A single front-loaded sentence with zero filler, and the permission constraint is placed where it matters. It is appropriately terse for such a short field set, though the brevity borders on under-specification for an execution tool.

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

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

For a command-execution tool with no annotations and no output schema, the description should explain safety profile, failure behavior, and return shape. None of that is present, leaving an agent unable to predict the consequences of invocation.

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

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

Schema description coverage is 100%, so all three parameters (seat_id, command_line, holder_session_id) are already documented in the schema. The description adds no parameter-level meaning beyond the schema, so the baseline 3 applies.

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

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

States a specific verb (Execute) and resource (terminal command) plus a scoping constraint (validated against seat domain boundary permissions). The seat-lifecycle siblings (claim_seat, release_seat, get_seat_status, list_seats) are distinct enough that an agent can route here without confusion, though the description never names or contrasts 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?

There is no explicit when-to-use guidance, no statement of prerequisites (e.g. must a seat be claimed first via claim_seat?), and no indication of which commands are permitted or rejected. The only implicit signal is the 'seat domain boundary permissions' phrase, which hints at validation but is not operational guidance.

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

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

No annotations are provided, so the description carries the full burden. It does disclose the returned facets (occupancy, holder session, lease, handover brief), which implies a side-effect-free read, but says nothing about authorization needs, behavior for an unknown/expired seat, or whether the lease/handover fields can be null.

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

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

A single sentence, front-loaded with the verb and resource, that packs in the four returned facets without a wasted word.

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

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

For a one-parameter read tool with no output schema, enumerating the returned fields in the description is exactly the right compensation. Only minor gaps remain (error/empty-seat behavior), so it is nearly complete.

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

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

Only one parameter and schema description coverage is 100%, with the schema documenting seat_id including an example ('domain:cli'). The description adds no extra meaning about the identifier's format or scope, so the baseline 3 applies.

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

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

Specific verb (Check) plus resource (seat) and an explicit enumeration of what is inspected: occupancy, holder session, remaining lease, handover brief. That distinguishes it from the mutating siblings claim_seat/release_seat, though it never names a sibling or contrasts itself with list_seats.

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 read-only inspection framing implies when this is useful (before claiming or releasing a seat), but there is no explicit when-to-use statement, no exclusion, and no pointer to alternatives such as list_seats for bulk status. Usage is left to inference.

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

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

With no annotations, the description carries the full behavioral burden. It implies a read and hints at return content (statuses, handover briefs), but says nothing about read-only guarantees, whether results are filtered or complete, pagination, or permissions.

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 naming the action first and the returned fields after. No filler, no restatement of the name.

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

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

For a zero-parameter read tool with no output schema and no annotations, the description is adequate but leaves the relationship to get_seat_status undefined and gives no sense of result scope or volume.

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

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

The tool takes zero parameters, so per the rubric the baseline is 4. The description correctly implies no input filtering is needed, though it adds nothing about how the result set is scoped.

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 (List) and resource (seats) plus the payload it returns (statuses, handover briefs). It is clear on its own, but it never distinguishes itself from the sibling get_seat_status, and 'available seats' sits in mild tension with also returning 'current statuses' for all seats.

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

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

There is no when-to-use guidance and no mention of the obvious alternatives (get_seat_status for a single seat, claim_seat/release_seat for mutations). The agent must infer the routing from the name alone.

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

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

With no annotations, the description carries the full burden. It usefully discloses that handover notes are treated as mandatory for the next agent session — notable since handover_notes is not in the schema's required list — but it says nothing about permissions, whether the release is reversible, what happens to the seat state, or the failure modes.

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

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

A single front-loaded sentence with no filler; the action precedes the requirement. Slightly compressed phrasing ('mandatory handover brief notes') 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?

For a three-parameter mutation tool with no annotations and no output schema, the description covers the core action and the notes requirement but omits the mutation's side effects, authorization expectations, and error behavior. Adequate, but with clear gaps an agent might need to probe.

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 100%, so all three parameters are already documented in the schema. The description reinforces handover_notes as mandatory and scopes it to 'next agent session', but adds no format or identity semantics beyond that. Baseline 3 applies when the schema does the heavy lifting.

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 (release a held seat) plus an attached requirement (handover notes). This clearly contrasts with the sibling claim_seat, though it never names siblings explicitly. An agent can tell what the tool does without opening the schema.

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

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

Usage is implied: release a seat you are holding, providing handover notes for the next session. There is no explicit statement of when NOT to use it, no mention of prerequisites (e.g. that you must be the holder) and no reference to alternative tools like get_seat_status or claim_seat.

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