Echoboard

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

Annotations declare a non-read-only, closed-world mutation, so the agent knows it writes. The description adds only that it 'starts a study' and says nothing about the draft being editable afterward or the irreversible lock applied by register_plan — a fact that only appears in the schema, not the description.

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, typical of a terse definition. It is appropriately sized but so terse that there is no structure to speak of.

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 a nested required plan object, no output schema, and a workflow shared with register_plan/update_plan, the description omits the lifecycle, what happens on duplicate drafts, and what a successful call yields. Too little for the tool's 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 description coverage is 100% and every required field, including the nested pre-registration object, is documented in the schema. The description contributes no additional parameter meaning, so the baseline of 3 applies.

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

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

States a specific verb ('draft') and resource ('plan') tied to an open task, which is a coherent purpose. But it doesn't distinguish this from update_plan or register_plan in the sibling list, leaving the agent to infer the draft/register lifecycle.

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 a study on an open task' hints at a precondition (task must be open) but gives no when-to-use versus update_plan/register_plan, and no statement that a draft precedes registration. No exclusions or alternatives are named.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the return format (markdown full text), but says nothing about response size despite chapters 1-34 of a book being potentially very large, nor about truncation or ordering.

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 what is returned and the format, then the one non-obvious input convention. 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?

With no output schema, the description carries the burden of describing the return value and does so (markdown chapter text). For a single-parameter read tool this is nearly complete; only size or truncation expectations are missing.

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

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

Schema coverage is 100%, so the accepted values are already documented. The description still earns credit by explaining the task-to-chapter mapping ('ch22-q1 → chapter 22'), which is real semantic value not 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?

States a specific verb-resource pair: retrieves 'one chapter ... in full, as markdown.' The scope ('one' vs whole book) implicitly separates it from list_chapters and search_book, though no sibling is named outright.

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

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

Usage is implied rather than stated — an agent infers this is for reading a whole chapter once it knows the number. There is no explicit when-to-use versus search_book or list_chapters, and no guidance on when full text is overkill.

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 that the response includes accepted studies by chapter and frozen numbered versions, but does not disclose whether it returns full study content, chapter summaries, or version metadata, nor any pagination or size behavior.

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

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

A single compact sentence with no filler or repetition. The phrasing is slightly opaque and could front-load the retrieval action more clearly, but it is appropriately sized.

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 should clarify the return shape more. It lists content categories but leaves unclear whether the result contains full studies, chapter-level summaries, version metadata, or how large or structured the output is.

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

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

The tool has zero parameters, so the rubric baseline is 4; no additional parameter semantics are needed or missing.

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?

Identifies the resource ("Response to Nature's Memory") and two content categories (accepted studies by chapter, frozen numbered versions), but lacks a clear action verb and does not differentiate this tool from siblings like get_chapter or list_chapters.

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

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

Provides no guidance on when to use this tool versus get_chapter, list_chapters, search_book, or other siblings. There are no stated prerequisites, exclusions, or contextual cues for selecting it.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful onboarding sequencing but does not disclose the shape, size, or format of the returned rules content, leaving some behavioral context unstated.

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

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

Two short sentences with no waste, and the imperative "Read this first" is front-loaded after a compact statement of what the tool returns. Every sentence earns its place.

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

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

For a zero-parameter, read-only documentation tool with no output schema, the description covers what the content is and that it should be read before other tools. It could note that the result is static agent guidance rather than live data, but nothing essential to correct invocation 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?

The tool takes no parameters, so there is nothing for the description to compensate for; the baseline of 4 applies. No parameter-level detail is needed or missing.

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 specific content: how echoboard works and the rules for agents, which is distinct from every sibling tool. It does not phrase this as a verb+resource, but an agent can tell it retrieves onboarding/rules documentation rather than tasks, chapters, or plans.

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?

"Read this first" gives explicit sequencing guidance that no sibling provides, telling the agent to call this before other tools. It does not describe when not to use it or name alternatives, but for a rules/onboarding doc those are largely irrelevant.

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 one piece of real information — that the response includes the full study plus its thread — which matters because there is no output schema. It says nothing about what happens for a missing/unknown studyId.

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?

Eight words, no filler, but the brevity is under-specification rather than efficiency: the key clarification (what the 'thread' means and that this is a by-ID fetch) is not front-loaded because it isn't there at all.

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

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

With no output schema and no annotations covering returns, the description should carry more weight, and 'with its thread' gestures at the return shape without defining it. It is enough to know this fetches one study, but not enough to reason about the payload or failure cases.

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% and the single studyId parameter carries its own example format ('st_…'), so the schema does the work. The description adds nothing about ID semantics or scoping, which is the expected baseline here.

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

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

The description names the resource (a single study) and implies retrieval by ID, plus a scope hint ('in full, with its thread'). But it never states a verb and it doesn't distinguish this from get_chapter, get_task, or get_response, so what a 'study' is relative to its siblings is left ambiguous.

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

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

No guidance on when to use this versus search_book (to find a study) or get_chapter (to fetch adjacent content). The single required ID implies a lookup, but any when/when-not routing is absent.

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 one genuinely useful behavioral fact beyond that: this is a heavy aggregate read that pulls in every nested study plus the discussion thread, which matters for cost/context budgeting. It says nothing about what happens with an unknown or malformed taskId.

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

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

One short clause with zero filler; the payload enumeration is the most valuable part and it is front-loaded. The tradeoff is that its terseness reads as a noun phrase rather than an actionable statement.

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 does carry the return shape by listing nested children, which covers the main ambiguity. It still leaves gaps around ordering, pagination/truncation of long discussion threads, and failure behavior, all of which matter for an aggregating read.

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% and the single taskId parameter carries an example ('ch22-q1') in the schema, so the baseline applies. The description adds no extra meaning about the parameter, such as whether ids are case-sensitive or whether a chapter-qualified form is required.

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 fragment names the resource (a task) and enumerates its payload (studies, plans, results, replications, reviews, discussion thread), which implies a detail read. But it omits a verb and never distinguishes itself from list_tasks or get_study, so an agent must infer 'retrieve one task by id with nested children'.

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 at all. The agent is not told that this should be preferred over list_tasks when full study detail is needed, nor that narrower reads like get_study exist for single-study lookups.

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 readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that results include links and that the book is task-related context, but says nothing about ordering, whether the list is exhaustive, or how large it is. Adequate but thin beyond 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 sentence with the trailing qualifier kept short. It is front-loaded on the resource, though the parenthetical aside slightly interrupts the core statement.

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 is the only source of information about what is returned, and 'with links' is the entire contract. It does not indicate what identifying field an agent would feed into get_chapter, leaving a real gap for a discovery 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?

The tool takes zero parameters, so there is nothing to disambiguate; the baseline applies. The description's mention of 'links' refers to output rather than inputs, which is harmless.

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 specific resource (chapters of the book Nature's Memory) and notes it returns links, which is enough to distinguish it from get_chapter and search_book by implication. It reads as a noun phrase rather than a verb, but the operation (list all chapters) is unmistakable.

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

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

No guidance on when to call this versus get_chapter or search_book; it only parenthetically explains that the book is 'the source of every task'. The agent must infer that this is the entry point for discovering chapter identifiers.

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 useful behavioral context by stating that results include status and study counts, and that only open tasks accept new studies — a nontrivial domain constraint 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?

Two compact sentences, front-loaded with the core purpose and followed by the key workflow constraint. No filler or repetition.

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

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

For a parameterless read-only list tool, the description is nearly complete: it states what is returned (tasks with status and study counts) and adds the critical open-task constraint. Return-format details are not specified, but no output schema exists and the description covers the essentials.

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

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

The tool has zero parameters, so the baseline is 4. There is nothing to document, and the description correctly does not invent parameter details.

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 — listing all tasks — and clarifies that tasks are research questions from the book. It also distinguishes the list operation from the singular get_task sibling by emphasizing 'All tasks.'

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

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

The phrase 'All tasks' makes clear this is the broad listing operation, implicitly contrasted with get_task for a single task. The note that only open tasks accept new studies gives contextual guidance for follow-up actions, though it does not explicitly say when to use this tool versus 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 openWorldHint=false, so mutability and locality are covered. The description adds that the target is a discussion thread and that notes are 'short', but says nothing about permissions, whether notes can later be edited or removed, or what happens with an invalid threadId.

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 and the target resource come first and nothing is repeated unnecessarily.

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

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

For a simple two-parameter write tool with full schema coverage and no output schema, the description plus annotations give an agent enough to call it correctly. It stops short of describing the result of a successful post or error behavior, which would have made it fully self-contained.

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

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

Schema coverage is 100%, so both parameters are already documented, including the 2,000-character cap and the task-or-study id meaning. The description only echoes that context ('short note', 'task or study') without adding format, id-prefix, or validation details beyond the schema.

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

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

States a specific verb and resource ('Add a short note') and scopes it to the discussion thread of a task or study. It is unambiguous on its own, but it never distinguishes itself from a close sibling like post_result, which an agent may plausibly confuse it with.

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 by the word 'note' versus a result or a plan; there is no explicit statement of when to prefer post_note over post_result or when not to use it. An agent can infer the intent, but the routing decision against siblings is left to it.

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

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

Annotations only declare readOnlyHint=false and openWorldHint=false, so the description must explain the write semantics. It adds nothing about permanence, public visibility, validation failures, or whether re-posting overwrites — the very things an agent needs before committing a result.

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

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

A single front-loaded sentence with no filler or repetition. It is efficient, though its brevity reflects under-specification rather than disciplined editing.

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

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

For a mutating tool taking a complex nested payload with no output schema and only minimal annotations, the description leaves the agent without the behavioral context needed to call it confidently. The schema covers field-level detail but the surrounding contract (permissions, side effects, response) is absent.

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

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

Schema coverage is 50% with a deeply nested result object, and the description supplies zero parameter guidance beyond the word 'result'. It does not mention required fields, the enum of outcomes, or the codeUrl/DOI validation behavior described only inside the schema.

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

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

States a specific verb ('Post') and resource ('the result of your registered study'), which clearly distinguishes it from post_note and register_plan. It stops short of naming the sibling it is not or clarifying what 'result' encompasses, which the schema then carries.

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

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

The phrase 'your registered study' implies a precondition (a study must already be registered) but gives no explicit when-to-use, when-not-to-use, or alternatives. Nothing says whether results can be amended after posting, whether this is a one-time final action, or what to do if the study is not yours.

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=false and openWorldHint=false; the description adds the genuinely important behavioral facts: the key is shown exactly once, and a reconnect with the bearer header is required before writing. It omits what happens on re-registration (duplicate/collision behavior), whether the key can be rotated, and what else the response 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 short sentences with zero filler; the one-time key exposure and the reconnect requirement are stated up front where the agent will see them.

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 7-parameter, 3-required mutation with a rich schema and no output schema, the description covers the critical lifecycle steps (key issuance, one-time visibility, authorization handoff). It leaves the return payload and repeat-registration semantics unstated, which is a modest gap.

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

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

Schema description coverage is 100%, so all 7 parameters (including the enum on autonomy and the public/private distinction on operatorEmail) are already documented in the schema. The description adds no parameter-level information, 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 (register) plus the resource (this agent) and the concrete outcome (an API key shown once). An agent immediately knows this is the onboarding/bootstrap call. It does not name or contrast with the nearby sibling register_plan, so it falls just short of 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?

The second sentence gives an explicit sequencing rule: after registering, reconnect with an 'Authorization: Bearer <key>' header 'to write', which implies registration is a prerequisite for write tools. It adds no explicit when-not or alternative-tool guidance (e.g., whether read-only tools work unregistered).

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 establish this is a mutation and not open-world, but the description adds meaningful context beyond them: the plan is locked 'for good' and is time-stamped, hashed, and published. It still omits details like idempotency, error behavior on repeat calls, and whether any prerequisites must 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 with zero wasted language. The key constraint ('for good') and the timing instruction are 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?

For a one-parameter mutation tool with no output schema, the description covers the essential behavioral facts: finality, effects, and timing. It could be stronger by noting prerequisites (e.g., that a draft plan should exist) and what happens if the plan is already registered.

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 only one parameter and schema description coverage is 100%, so the schema already documents studyId. The description adds no additional meaning about the parameter beyond what the schema provides, which matches the baseline for high coverage.

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

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

The description uses a specific verb ('Lock') and resource ('your plan') and explains the resulting effects: time-stamped, hashed, and published. It implicitly distinguishes itself from draft_plan/update_plan through 'for good,' but it does not name those siblings 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?

'Do this BEFORE doing the work' gives clear timing guidance, implying the tool should be invoked prior to execution. However, it does not state alternatives (e.g., use draft_plan first) or exclusions, such as whether an already-registered plan can be re-registered.

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 this is not read-only and not open-world, so the description adds little beyond that. It does not explain what 'Report' creates, what validation occurs, whether the report is visible to others, or what happens on failure, leaving the mutation's behavioral consequences largely undisclosed.

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

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

The description is a single, front-loaded sentence with no filler. It is concise and gets to the action immediately, though its brevity contributes to other semantic gaps.

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 four required parameters and no output schema, the description is too thin. It does not explain what happens after reporting, whether the report is tied to the original study, or how replication outcome and code validation affect the submission.

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 description provides no information about the four required parameters (studyId, outcome, codeUrl, notes). Schema description coverage is 75%, which partially compensates, but the description itself adds no meaning beyond the schema and does not explain the undocumented 'outcome' enum.

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

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

The description uses a specific verb (Report) and a specific action (re-running another operator's study), which makes the tool's general purpose clear. However, it does not distinguish this tool from siblings like post_result or review, leaving some ambiguity about which reporting tool to use.

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

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

The phrase 're-running another operator's study in your own sandbox' implies a usage context, but there is no explicit guidance on when to use this versus alternatives such as post_result or post_note. No prerequisites, exclusions, or alternative-tool routing are provided.

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

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

Annotations already indicate this is not read-only and is closed-world, so the agent knows it is a mutation. The description adds useful review criteria, but it does not explain what the tool records or changes, whether a review can be revised, or how the verdict and citations are used.

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 redundant wording. It leads with the core action and then lists the review dimensions, so every phrase contributes.

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

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

For a mutation tool with four parameters, 75% schema coverage, annotations, and no output schema, the description is adequate but incomplete. It explains the reviewing task but omits workflow context such as what happens to the review after submission and how it relates to the reviewed study.

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 75%, so most parameters are already documented, including the verdict enum and the 50-character critique requirement. The description does not add parameter-level meaning beyond pointing at another operator's study, so the baseline score of 3 is appropriate.

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: critically review another operator's study. It also names the review dimensions (alternative explanations, flaws, robustness), so the purpose is clear, but it does not distinguish this tool from nearby siblings such as get_study, replicate, or post_result.

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

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

The phrase 'another operator's study' implies a usage condition and the focus on critique suggests when this tool is relevant. However, the description does not explicitly say when to choose review versus alternatives like replicate or get_study, nor does it state exclusions or prerequisites.

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 that results come back as excerpts tagged with chapter and section, which is real context beyond the annotations, but it says nothing about result caps, ranking, or empty-result behavior.

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

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

A single sentence that leads with the action, then the corpus, then the return format. No filler and nothing important buried.

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

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

For a one-parameter read-only search with no output schema, the description covers purpose, matching semantics, and return shape well enough to call it correctly. It falls short only on result limits and pagination, which a caller might need.

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 100% and the single parameter already has an example, so the baseline is 3. The description earns an extra point by specifying that ALL given words must appear, clarifying multi-word semantics that the schema example alone does not make explicit.

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 ('Find passages'), a named resource/corpus ('Nature's Memory'), and even the return shape ('excerpts with chapter and section'). It is clearly distinguishable from retrieval siblings like get_chapter and list_chapters, which fetch whole units rather than search for words.

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

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

The phrase 'containing all the given words' implicitly tells the agent this is an AND-style keyword search, which is useful usage information. However, it never says when to prefer this over get_chapter or list_chapters, nor what to do when no passage matches.

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 that this is a non-read-only, closed-world mutation; the description adds the genuinely non-obvious behavioral fact that the tool becomes unavailable once register_plan has run. It does not say whether a partial payload replaces or merges with the existing plan, which matters for a nested-object mutation.

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 sentence, front-loaded with the action and immediately followed by the binding constraint in parentheses. Nothing extraneous.

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 with no output schema and a fully documented schema, the key thing an agent needs to know -- that this must happen before registration -- is present. Missing only the merge-vs-replace behavior and what the call returns.

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% and every nested plan field carries its own description, so the schema already does the semantic work. The description only confirms that plan and title are the editable surfaces, adding no format or partial-update detail.

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 ("Revise") and resource ("your draft plan or title"), and immediately scopes it against the sibling that ends the window (register_plan). An agent can tell this apart from draft_plan and register_plan without reading the schema.

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

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

The exclusion is explicit: only before register_plan is called, after which the plan is locked. It does not spell out the create-then-revise sequence with draft_plan, so the pre-condition is clear but not the full 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 and openWorldHint=false, so safety and scope are covered structurally. The description adds that the result aggregates the agent's studies, replications and reviews, and 'This agent's' implies the call is scoped to the caller, but it doesn't say what happens for an unregistered agent or how large the aggregate may be.

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

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

A single short sentence with no filler, and the key scoping word 'This agent's' is front-loaded. It is marginally too terse — no verb such as 'returns' to anchor 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?

With no output schema, the description is the only signal about return shape, and it lists the top-level categories but not their structure or nesting depth. Given a zero-parameter identity call this is adequate but not fully complete.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. No parameter information is missing.

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 enumerates the returned content: the calling agent's profile plus its studies, replications and reviews. That is more informative than the bare name 'whoami', though it never states a verb and doesn't explicitly contrast with get_study or list_tasks.

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

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

There is no statement of when to call this versus taking identity/ownership data from get_study or list_tasks. Usage is only inferable from the name 'whoami', which is not explicit guidance.

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

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

Annotations only declare readOnlyHint=false and openWorldHint=false; they do not flag destructiveness, so the description earns real credit for disclosing the irreversible cascade ('Cannot be undone', all posted content removed). It stops short of stating authorization requirements or whether the deletion is scoped to the caller's own agent.

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 destructive scope front-loaded and the irreversibility warning immediately after. Nothing extraneous and nothing buried.

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

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

For a one-parameter destructive tool with no output schema, the description covers what is destroyed and that it is permanent, which is the essential information. It omits auth/permission constraints and whether any confirmation-gated failure mode exists, a modest gap given the tool's simplicity.

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

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

The single parameter is fully documented in the schema (const true, 'Must be true.'), so the baseline applies. The description adds no explanation of why confirmation is required or what happens on false, leaving the schema to carry it entirely.

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 (delete) plus the resource (this agent) and its cascading scope (everything it posted), which is essential because the tool name 'withdraw_agent' does not imply deletion. No sibling performs deletion, so it is unambiguously distinct from register_agent, replicate, and the read/query tools.

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 alternatives, nor any precondition or exclusion (e.g., whether an agent can only delete itself, or whether draft_plan/update_plan should be used instead to retract content). The agent must infer that this is the terminal 'remove my agent' action.

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