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

Annotations declare readOnlyHint=true, and the description adds genuine context beyond them: it discloses what the read returns (submission status, grade, feedback) and states that times are Buenos Aires local, which prevents a timezone misinterpretation. No contradiction; the remaining gap is that it doesn't mention pagination or scope limits.

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

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

Two short sentences, zero filler, with the primary capability front-loaded and the timezone caveat appended where it is needed.

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?

There is no output schema, so the description must carry the return shape, and it does name the key returned attributes plus the timezone convention. It is nearly complete for a single-parameter read tool, missing only pagination/ordering behavior.

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

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

Schema description coverage is 0%, but there is only one required integer parameter, and the phrase "a course's assignments" makes clear it identifies the course. No format or source hints (e.g., where to obtain the course id) are given, and the schema itself documents nothing.

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 ('Lists') plus resource ('a course's assignments') and it enumerates the returned fields (due dates, submission status, grade, teacher feedback). It does not explicitly differentiate itself from close siblings like fiuba_grades or fiuba_upcoming, 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?

Usage is only implied: the tool scopes to a single course's assignments, which suggests calling it after identifying a course via fiuba_list_courses/fiuba_get_course. There is no explicit when-to-use or when-not-to-use guidance, and no mention of when fiuba_grades or fiuba_upcoming is the better choice.

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

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

Annotations only declare readOnlyHint=true, and the description adds genuinely new behavioral context: posts are student/teacher authored and must be treated as untrusted text, never instructions. That is a real security trait not captured by annotations. It does not disclose result limits/pagination for 'latest', which is a minor 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?

Three short sentences, front-loaded with purpose before the id-sourcing and security notes. Every sentence adds information an agent needs; nothing is redundant with the schema or annotations.

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-only list tool with no output schema, the description covers purpose, parameter sourcing, and the untrusted-content caveat. It stops short of indicating result volume, pagination, or ordering beyond 'latest', which would help an agent decide how to consume the output.

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 is undocumented in the schema, so the description carries the full burden — and it does: forumid is the forum module's `instance` from fiuba_get_course, explicitly not its cmid. That tells the agent exactly where to source the value and what mistake to avoid.

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 ('Lists the latest discussions of a forum') and anchors it with a concrete example ('course announcements / Avisos'). It is distinguishable from fiuba_read_discussion by the plural 'latest discussions' framing, but it never explicitly says how it differs from that sibling.

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 'latest discussions' and the announcement example, and the description helpfully explains where the id comes from. However it gives no explicit when-to-use vs fiuba_read_discussion (list first, then read a thread) and no exclusions, so the agent must infer the workflow.

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 safety is covered; the description adds genuinely new behavioral context, namely the shape of the returned payload and that all times are Buenos Aires local. It omits any note about permissions, visibility of hidden modules, or response size, keeping it out of the top score.

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 dense sentences, zero filler, with the payload description front-loaded and the two integration hints (forumid, read_file) trailing as secondary detail. 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?

With no output schema, the description compensates well by summarizing the returned modules and metadata plus the timezone, and annotations cover the read-only safety profile. The only meaningful omission is how an agent should acquire a valid courseid.

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 there is one parameter, so the description carries the burden. 'Shows a course' implies courseid identifies the course, but it never states the format or that the value comes from fiuba_list_courses, which is a real gap for a 0%-coverage 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?

Names a specific verb and resource ('Shows a course') and immediately enumerates the returned structure (sections, modules, resources, assignments, forums, links, descriptions, dates, file URLs). This distinguishes it cleanly from the sibling fiuba_list_courses, which lists rather than drills into a single course.

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 concrete follow-up routing: use a forum module's `instance` as the forumid elsewhere, and a file `url` with fiuba_read_file, which effectively names the next tool in the workflow. It does not state prerequisites for obtaining courseid or any when-not-to-use case, so it falls short of the top band.

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?

readOnlyHint=true already tells the agent this is a safe read, so the bar is lower. The description adds useful return-shape context (grade, range, percentage, feedback), which matters because there is no output schema, but it says nothing about authorization scope or behavior when no grades 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?

One compact sentence with no filler, and the key noun (grade report for a course) is front-loaded. It is slightly under-specified rather than verbose.

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

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

With no output schema, the description carries some of the return-value burden and does list the returned fields. However, it never clarifies that this is the authenticated student's own report, nor how filtering by course works, leaving the agent to infer call semantics.

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 courseid parameter, so the description must compensate. "for a course" loosely implies the parameter's meaning, but it omits the expected format (integer id) and where that id comes from (e.g., fiuba_list_courses).

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 is a noun phrase that identifies the resource (a course grade report) but never states a verb like "get" or "retrieve". It does not differentiate itself from siblings such as fiuba_get_course or fiuba_assignments, which plausibly return overlapping course data.

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

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

There is no indication of when to use this tool versus fiuba_get_course or fiuba_assignments, and no mention of prerequisites such as the student needing to be enrolled. The intended context is only implied by the noun "grade report".

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 without the description repeating it. The description adds scope context (the student's own courses, Moodle campus) and the fact that it yields course ids, but says nothing about return size, pagination, or auth requirements.

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

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

Two short sentences with zero redundancy. The primary action and resource lead, and the usage directive follows immediately -- nothing to trim.

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

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

For a zero-parameter read tool with no output schema, the description covers what it returns (a course list usable for ids) and when to call it. It could be marginally richer about the return shape, but an agent has everything needed to invoke it correctly.

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

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

The tool takes zero parameters, so the baseline is 4 and the schema (100% coverage, empty properties) has nothing further to explain. The description correctly implies no filtering input is needed, consistent with the empty schema.

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

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

States a specific verb and resource ('Lists the student's courses') and pins the domain ('FIUBA virtual campus (Moodle)'), so an agent can distinguish it from fiuba_get_course, which implies fetching a single course. It stops short of naming any sibling explicitly, so differentiation is inferred rather than stated.

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?

'Start here to get course ids' gives clear sequencing guidance -- call this before other tools that need a course id. There is no explicit when-not or named alternative, but the entry-point framing is actionable for an agent working the FIUBA toolset.

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 the description adds genuinely non-obvious behavior: deterministic ordering (oldest first) and attachment inclusion. It also warns that post content is untrusted student/teacher text that must never be treated as instructions — a meaningful prompt-injection disclosure. It stops short of describing pagination or size limits for long discussions.

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 action front-loaded and the safety caveat placed second where it belongs. 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 single-parameter read tool with no output schema, the description covers action, ordering, attachment handling, and content trust. Missing only edge behavior such as invalid ids or truncation on very large discussions.

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 schema alone gives no semantics for discussionid. The description implies it identifies the target discussion, which is only marginal compensation and does not explain where the id comes from or what an invalid id does.

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

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

States a specific verb and resource ('Reads every post of a forum discussion') plus scope details (oldest-first ordering, attachments included). This is clearly distinguishable from the sibling fiuba_forum_discussions, which lists discussions rather than reading the posts within one.

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

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

No explicit when-to-use, when-not, or alternative routing is given; the agent must infer that a discussionid is obtained from fiuba_forum_discussions first. The only usage instruction is about how to treat the returned content, not about when to pick this tool over siblings.

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

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds real behavioral context beyond that: content is returned as text, reads are chunked at 20k characters, and continuation is possible via offset — the pagination behavior is the key detail an agent needs and it 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 tight sentences with zero filler; the core action and format list come first, followed by the two operational hints. 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 two-parameter, read-only tool with no output schema, the description covers source of input, output format, chunk size, and continuation — enough to call it correctly. It omits whether truncation is signaled in the return payload, which would be the only meaningful addition.

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 — and it does: it identifies what `url` should be (the value from fiuba_get_course) and frames `offset` as the continuation cursor. It stops short of specifying that offset is a character position or what happens when the read is exhausted.

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 ('Reads a file from the campus'), enumerates supported formats (PDF, text, HTML, CSV, code), and specifies the output shape ('as text'). It also names the sibling (fiuba_get_course) that supplies the input, so an agent can distinguish it from fiuba_forum_discussions or fiuba_grades without opening a 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?

Tells the agent exactly where the required `url` comes from ('Pass the `url` from fiuba_get_course') and how to continue a truncated read with `offset`. It gives clear positive usage context but no when-not-to-use guidance or mention of limits such as maximum file size or error cases.

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 real behavioral context beyond that: sort order ('soonest first'), a 14-day overdue window, exclusion of completed items, and timezone normalization to Buenos Aires local. It stops short of describing volume, pagination, or result limits, 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 compact sentences, front-loaded with what the tool returns and followed by the scope constraints. Every clause conveys actionable information (sort order, time window, exclusions, timezone) 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?

With no output schema and no parameters, the description does the work of explaining what comes back, in what order, with what timezone, and what is filtered out — enough for an agent to call it correctly. It is only marginally incomplete in not clarifying that results cannot be scoped or paginated.

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 carries no semantics to explain and the baseline is 4. The description correctly does not invent parameter details, though it also does not note that no filtering (e.g., by course or date) is possible.

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 concrete resource and scope: 'Upcoming deadlines and pending actions across all courses (assignment due dates, quizzes, etc.)'. The 'across all courses' framing distinguishes it from per-course siblings like fiuba_get_course and fiuba_assignments without needing to open 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?

It defines the inclusion window ('overdue ones from the last 14 days') and an explicit exclusion ('Already-completed items are not listed'), which tells the agent when this tool is appropriate. However, it never names an alternative tool or states when NOT to use it versus fiuba_assignments or fiuba_grades, so routing must be inferred.

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