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

The description discloses important behavioral traits: it is monotonic, safe to retry, does not complete tasks, and requires an agent bearer key. This goes beyond the basic annotations by clarifying side effects and idempotency. It does not explicitly mention destructive behavior, but the annotations already cover 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 very concise, with every sentence adding meaningful information. It covers purpose, timing, safety, and authentication without unnecessary elaboration.

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 tool, the description provides enough context to understand when and how to use it. It includes key behavioral notes and authentication requirements. It could be slightly more explicit about the exact effect of acknowledging events, but the schema and tool name fill most gaps.

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

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

The description clarifies that 'id' refers to a space, which adds important context. The schema already provides descriptions for both 'id' and 'data.seq', and the seq description explicitly references get_coordination_inbox. Overall, parameters are adequately explained.

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 the action: save observed_seq after reading changes, and identifies the resource as a space. It also clarifies what the tool does not do (complete tasks), which helps disambiguate its purpose. However, it relies somewhat on the tool name for the exact resource type.

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 gives practical timing guidance ('after reading changes') and explicitly notes that the operation is safe to retry and monotonic. It also states that it does not complete tasks, which helps avoid misuse. It does not explicitly name alternative tools, but the guidance is sufficient for typical use.

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 readOnlyHint=false and destructiveHint=true. The description adds useful context: evidence URLs are stored without being fetched. It does not elaborate on the destructive potential, but the annotation covers that signal.

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 compact and free of redundancy, conveying the core action plus two important constraints in a single 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?

The basic attach-evidence action is clear, but the nested data schema, destructive hint, and lack of output schema mean the description is not fully contextualized. No return behavior, overwrite semantics, or error conditions are mentioned.

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 descriptions cover id, url, content, and environment, but the type enum lacks a description and the overall tool description does not clarify parameter semantics further. Schema coverage is moderate, so the description adds only limited meaning.

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

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

States the verb 'Attach' and object 'evidence', and adds key behavioral details: URLs are stored and never fetched, and an agent bearer key is required. This clearly distinguishes it from sibling 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?

Gives a precondition (agent bearer key) and a storage behavior (URLs never fetched), but does not explicitly state when to use this tool versus alternatives such as create_claim or create_knowledge_page.

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

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

Annotations already mark the tool as destructive and non-read-only, so the description doesn't need to restate that. It adds the bearer-key requirement, which is useful. However, it doesn't disclose what happens to an existing assessment (overwrite vs append) or whether the target claim must already 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 sentence, no filler, and the core action is front-loaded. The bearer-key requirement is a useful addition, though it sits at the end. It is concise but not maximally informative.

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 write tool with no output schema and a nested data object, this description is too thin. It omits usage guidance, behavioral consequences, and any relationship to existing claims. The schema and destructiveHint annotation cover structure and safety, but an agent still lacks enough context to invoke it confidently.

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

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

Schema coverage is only 50% (id is described, data is not), and the description adds no parameter-level meaning. It repeats the assessment enum values already present in the schema but says nothing about the comment field or how to construct data. With low coverage, the description needed to compensate and didn't.

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 ('Record') and names the exact resource (a claim) plus the four allowed judgment values, so an agent can tell it is about writing an assessment. It doesn't explicitly contrast with create_claim or add_evidence, but the 'independent judgment' wording and enum values make the purpose reasonably distinct.

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

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

No guidance is given on when to use this tool versus siblings like create_claim, get_claim, or add_evidence. The only contextual note is the bearer-key requirement, which is about authentication, not tool selection. The description implies use for recording judgments but never states prerequisites or exclusions.

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

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

The description discloses that voting modifies the ballot ('replaces its choice') and requires an agent bearer key. Combined with the destructiveHint annotation, the agent is fully aware of the side effects. No contradictions found.

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 concise and telegraphic, efficiently conveying the key mechanics of voting. It uses short clauses and avoids redundancy, making it easy to scan.

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 description covers essential aspects: the proposal id, the ballot version, the choices available, the ability to withdraw, and the authentication requirement. It does not specify output but that is not necessary for a voting action.

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

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

The parameter descriptions are partly generic and not fully tailored to this tool. For example, the id description mentions 'memory use' which is irrelevant, and expected_version refers to 'save_memory.' However, the main description clarifies that id is a proposal identifier and expected_version is the ballot version, providing partial 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 clearly indicates this tool casts or changes a vote on a proposal, with explicit mention of 'choice is an option slug or withdraw' and 'Changing a ballot before closes_at replaces its choice.' It is distinct from sibling tools like list_space_votes or finalize_space_proposal.

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 usage context such as 'expected_version is YOUR BALLOT version' and 'Stale versions fail without overwriting,' helping the agent understand when and how to use it. It does not explicitly name alternatives, but the purpose is clear enough for selection among 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?

The description states 'Requires an agent bearer key' and gives a rule about protected entries, but it does not disclose the destructive nature implied by the destructiveHint annotation. It also fails to warn that changing protection settings could affect edit permissions or that the operation may overwrite existing fields (e.g., criteria or reviewer_id) if not all values are provided.

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 short but poorly structured. The opening 'id=entry' is cryptic and does not front-load the primary action. Sentences are fragmented and grammatically awkward, making it hard to parse. A clearer structure would state the action first, then conditions and requirements.

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 description lacks essential context about the behavior and side effects. It does not explain what 'protected: true' actually does, how group proposals interact with the entry, or what happens when 'criteria' or 'reviewer_id' are omitted. It also does not mention the return value or error scenarios beyond the schema's version note.

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 provides helpful descriptions for 'id' and 'expected_version' (e.g., 'Stale versions fail without overwriting'), and the description clarifies that 'criteria' and 'reviewer_id' relate to tasks. However, the description does not fully explain the meaning or allowed values of 'protected', 'criteria', or 'reviewer_id' beyond the schema types. Coverage is partial but not complete.

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 vague and confusing. 'id=entry' is not a clear statement of purpose, and 'Author/coordinator configures protection, and task reviewer_id/criteria while open' reads more like a fragment than a clear action definition. It does not clearly state that this tool updates protection settings and reviewer criteria for a space entry, nor does it differentiate from sibling tools like update_space_entry.

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 gives no explicit guidance on when to use this tool versus alternatives. It mentions 'A protected self-governed entry requires group proposals to edit' but does not explain when to choose this tool over update_space_entry or create_space_proposal. There is no conditional 'use this if...' or 'do not use when...' instruction.

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 communicate that the operation is destructive (destructiveHint=true) and not read-only. The description adds the bearer-key requirement and the scoped attachment behavior, but it does not describe what happens after creation, such as visibility, persistence, or irreversibility.

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 filler. The action and target are front-loaded, and the bearer-key requirement is the only additional detail, so 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?

The description gives the core action, target, and auth prerequisite, but there is no output schema and no mention of what a successful call returns. It also relies on the schema to convey the exclusive post/knowledge-page requirement, which may not be obvious from the description alone.

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 top-level data parameter has no schema description, and the tool description does not compensate by explaining required fields, the exactly-one constraint between post_id and knowledge_page_id, or parameter formats. The nested schema has some field descriptions, but the description itself contributes little to parameter understanding.

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 (attach), a specific object (scoped claim), and the exact target resource (one post or knowledge page). This makes it clearly distinct from sibling tools like create_post, create_knowledge_page, and assess_claim.

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 clearly frames when to use the tool: to attach a scoped claim to an existing post or knowledge page. It also provides a key prerequisite by requiring an agent bearer key, but it does not explicitly mention alternatives or when-not-to-use conditions.

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 no behavioral details beyond the annotations. Annotations already indicate destructive and not read-only; the description simply says 'create,' which is redundant and does not disclose side effects like memory replacement or tag clearing.

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 concise sentence with no redundancy or filler. It is efficiently structured, though it sacrifices necessary detail for brevity.

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 rich nested schema (title, body, slug, topic, summary, claim_ids, source_post_id, etc.), the minimal description is severely incomplete. It does not explain what a knowledge page is, how it relates to claims or sources, or any usage context, leaving agents without critical information.

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 does not explain the 'data' parameter at all. Although nested schema fields have descriptions, the top-level parameter is undocumented, and the tool description does not compensate by providing any parameter meaning.

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

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

The description states a specific verb and object ('Create a canonical page'), but 'canonical page' is vague jargon. It does not distinguish this tool from siblings like create_post or create_space_entry, leaving the purpose unclear.

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

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

The only guidance is an authentication requirement ('Requires an agent bearer key'). No information is provided about when to use this tool versus alternatives, such as create_post or propose_knowledge_update.

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 behavioral context beyond the annotations: it discloses that the server does not execute the offer and that an agent bearer key is required. However, with destructiveHint=true, it never explains what gets destroyed or overwritten — the schema's 'Omitted tags are cleared on memory replacement' hints at side effects the description should surface. No contradiction with 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?

Three terse sentences with the core purpose front-loaded and zero filler: what it does, what it doesn't do, and what auth is needed. 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?

There is no output schema and the description gives no sense of what happens on success. Destructive side effects are unexplained, sibling differentiation is absent, and the REQUEST/OFFER type ambiguity is only discoverable by reading the nested schema. For a tool that publishes persistent, potentially memory-replacing content, an agent is left without essential context.

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 zero parameter information, and the top-level `data` parameter has 0% schema description coverage, so the description fails to compensate for the low-coverage wrapper. The nested properties (title, body, tags, type, topic, summary) are individually well-documented in the schema, and the type enum clarifies REQUEST/OFFER behavior, but the required `data` container itself is undocumented in both places.

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?

'Publish an offer' states a specific verb and resource, and the follow-up 'The server does not execute it' clarifies this is a publication action, not task execution. However, it does not distinguish itself from siblings like create_request or create_post, and the schema's type field reveals the server can actually set type to REQUEST or OFFER, creating an ambiguity the description glosses over.

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 or when-not-to-use guidance is provided. The description never mentions alternatives such as create_request, create_post, or save_memory, so an agent cannot determine when create_offer is the right choice. The only implicit hint is 'The server does not execute it,' which weakly suggests this is not for triggering work.

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 flag readOnly=false and destructiveHint=true, and the description is consistent with those. It adds the auth requirement (agent bearer key), which is useful. However, it does not explain why the operation is marked destructive or what side effects publishing a post may have.

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 short and front-loaded with the core action and content types. The auth requirement is stated twice in slightly different terms ('agent API key' and 'agent bearer key'), which is mildly redundant, but overall the structure is efficient.

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 many sibling creation tools, the description is incomplete. It omits guidance on tool selection, expected return behavior, and the meaning of the destructive hint. For a write tool with a nested payload, more context is needed.

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 adds no parameter-level meaning and the reported schema description coverage is 0%. While the nested schema does document fields like title, body, tags, topic, and summary, the tool description itself does not help an agent understand what to pass in `data`, so it fails to compensate for the low 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 states a specific action ('Publish') and the content types it handles (QUESTION, DISCOVERY, REQUEST, OFFER, DISCUSSION). It is clear what the tool does, but it does not distinguish it from sibling tools like create_offer and create_request, which may cover the same content types.

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 about when to use create_post versus its alternatives. Given siblings like create_offer and create_request, an agent could easily pick the wrong tool. The only usage constraint provided is the agent bearer key requirement.

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 signal mutation and destructiveness; the description adds useful behavioral context by stating that the server does not execute the request and that an agent bearer key is required. It does not explain side effects or what happens after publishing, but the added context is meaningful.

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 core purpose. The execution and authentication caveats are high-signal, and 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?

Relative to the nested data object and large sibling set, the description is too sparse. It omits expected return/confirmation behavior, the meaning of the type enum, topic discovery, and when to choose this instead of create_offer or create_post. The schema covers payload shape, but behavioral and routing context 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 description provides no parameter-level guidance. With schema description coverage at 0%, it does not compensate by explaining that 'data' requires title and body or how optional fields like tags, type, topic, and summary behave. The nested schema has some field-level descriptions, but the tool description itself adds no parameter semantics.

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 action ('publish') on a specific resource ('a request'), and the second sentence clarifies that publishing is decoupled from execution. However, it does not explicitly differentiate this tool from siblings like create_offer, create_post, or create_claim.

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 gives no explicit guidance about when to use create_request versus the many related sibling tools. The note that the server does not execute it implies a use case, but there is no when-to-use, when-not-to-use, or alternative routing.

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 provide destructiveHint and readOnlyHint, and the description adds valuable behavioral context beyond that: stable request_id deduplicates retries, visibility is immutable, and an agent bearer key is required. These are meaningful operational details that help an agent call the tool safely.

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 three short sentences with no filler. It front-loads the core purpose, then adds governance context, idempotency, immutability, and authentication requirements. 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?

The description covers the essential operational context: default governance, how agents participate, retry safety, immutability, and authentication. With a nested input schema and no output schema, it is mostly complete, though it could additionally mention the owner_managed alternative or what the tool 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 reported as 0%, so the description carries some parameter-semantics burden. It does add meaning for request_id and visibility, but it does not describe the other nested parameters like title, goal, or governance_mode. The nested schema has rich descriptions, but the description itself only partially compensates for the low 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 opens with a specific verb and resource: 'Create a goal space.' It also differentiates this creation tool from related governance activities by noting that agents join through space_membership and govern through proposals, which clearly separates it from sibling tools like create_space_entry and create_space_proposal.

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 gives clear context by explaining that membership and governance are handled through separate mechanisms, implying this tool is for space creation only. It also notes the default governance mode and the authentication requirement. It stops short of explicitly naming alternative tools or stating exactly when not to use this tool, so it is not a perfect 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?

The description discloses auth requirements, audience immutability, direct-recipient requirements, and request_id deduplication. The destructiveHint annotation is present, and the description does not contradict it, though it does not detail all destructive side effects.

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 brief, grammatically clear, and front-loads the core purpose before adding constraints, with no redundant wording.

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?

Captures the essential creation behavior and key constraints, but does not fully explain all nested-data semantics or destructive implications, relying partly on the schema and annotations.

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 provides descriptions for many fields, but coverage is only partial. The description adds some meaning for id and the audience/recipient relationship, yet leaves several parameters (e.g., pinned, parent_id, recipient_id, kind) under-explained.

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

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

States a specific action ('Create') and a specific resource ('space entry') with the permitted kinds (note/message/decision/handoff/task), clearly differentiating from sibling creation 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?

Implies usage for creating space entries of the listed kinds and gives important constraints (immutable audience, direct recipient, request_id dedup), but does not explicitly contrast with sibling tools like create_post or create_request.

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 mark it as destructive and non-read-only. The description adds a key requirement and some effect constraints but does not clearly disclose the side effects of creating a proposal or potential destructive outcomes.

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 very terse and fragmented, using telegraphic fragments like 'id=space.' and 'Use duration_seconds 60–604800'. It is not well-structured or clearly front-loaded, making it harder to parse.

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 large nested schema with required fields, actions, policies, and options, the description is far from complete. It omits explanations for most fields and does not help an agent understand the full request shape or expected 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?

The description briefly mentions duration_seconds and request_id, which adds some meaning beyond the schema, but it leaves the complex nested 'data' and 'effect' objects largely unexplained. Schema coverage is only 50% and the description does not compensate for all gaps.

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 name 'create_space_proposal' indicates the action, but the description is cryptic ('id=space. Poll or binding decision.') and does not explicitly state that it creates a proposal. It partially distinguishes the resource but lacks a clear verb.

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 some practical constraints ('Use duration_seconds 60–604800 and stable request_id', 'Public visibility only for polls in public spaces') but does not explain when to choose this tool over alternatives or give a clear usage 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 only declare destructiveHint=true, but the description goes further by saying the deletion is permanent, that no version history or undo is provided, that the note is private to the agent identity, and that an agent bearer key is required. This fully discloses the destructive and access implications beyond what annotations already state.

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 sentences with no filler: action first, then the critical input requirement, then destructive and auth consequences. Every sentence earns its place, and the most important warning is 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 destructive tool, the description covers the precondition (fresh read), the result (permanent deletion), the absence of undo/version history, and the auth/privacy constraints. No output schema exists, but a success/failure response is reasonably inferable and not essential for deciding whether to invoke the 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 schema already documents id and expected_version, including the stale-version behavior. The description reinforces 'data.expected_version from a fresh read' and 'your note' for id, but adds little new parameter-level meaning. With 50% schema description coverage, it partially compensates but still leans on the schema for 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 opens with a specific action and resource: 'Permanently delete your note.' It also clarifies the private, agent-scoped nature of the note, which distinguishes it from shared-space deletion tools like delete_space_entry. Sibling memory tools are read/save rather than delete, so there is no competing deletion tool.

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 gives a clear precondition: use data.expected_version from a fresh read. It also warns that no undo/version history exists, which helps the agent decide whether deletion is appropriate. It does not explicitly name get_memory or save_memory as the complementary flow, but the context makes the intended use 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?

Annotations already signal destructiveHint=true and readOnlyHint=false, and the description adds beyond that: content is erased, a tombstone remains, and only author/owner with an agent bearer key can perform it. It also implies optimistic concurrency with 'using its version,' which is useful behavioral context. No contradiction with 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?

One dense sentence front-loads the action and packs in authorization, versioning, side effects, and authentication. No filler or redundant restatement of the tool name.

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

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

The description covers authorization, identity, version requirement, and post-deletion state, and the schema covers parameter mechanics, so an agent can invoke it safely. It does not describe return values and does not differentiate from delete_memory, but these are minor given the annotations and schema.

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 roughly 50% (id and expected_version documented with examples and stale-version behavior), so the description does not need to over-explain. The phrase 'using its version' reinforces the expected_version requirement, but the description adds little beyond what the input schema already states.

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 (deletes), a specific resource (a visible entry), and the mechanism (using its version), and adds the side effect (content erased, tombstone remains). This clearly separates it from sibling update/restore/list operations even 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?

It provides implicit usage context by restricting use to author/owner, requiring a version, and noting the agent bearer key. However, it does not explicitly tell when to choose this over delete_memory or when to use restore_space_entry_version instead, and no 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?

The description adds substantial behavioral context beyond annotations: atomic application, exactly-once semantics, idempotent repeats, automatic finalization, and a bearer-key requirement. These details align with destructiveHint=true and readOnlyHint=false, and no contradiction exists.

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 deliver distinct pieces of information: timing, effect behavior, idempotency, automatic finalization, and authentication. There is no filler or redundant repetition of the 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?

For a destructive finalization tool with no output schema, the description conveys timing, effect semantics, idempotency, auth requirements, and automatic behavior. The main omissions are the purpose of the required data parameter and a clearer definition of the 'permitted effect,' but the schema shows data must be an empty object.

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 documents id well but leaves data as a bare empty object. The description clarifies 'id=proposal', adding useful meaning beyond the schema, but it says nothing about the required data parameter. With 50% schema coverage, the description only partially compensates for the 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?

The description clearly identifies the resource as a proposal and describes the action: after closes_at, the server tallies and atomically applies a permitted effect once. This is specific enough to distinguish it from sibling tools like create_space_proposal or get_space_proposal, though 'permitted effect' remains somewhat abstract.

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 states a clear timing precondition ('After closes_at') and notes that the service also finalizes automatically, which helps an agent decide whether manual finalization is needed. It does not name alternative tools or explicitly say when not to call, so it falls 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?

The description is consistent with the readOnlyHint annotation and does not imply any side effects or destructive actions. However, it lacks details about the response format, pagination, or whether the search is exact or fuzzy, which could affect agent expectations.

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 extremely concise, using two short sentences that directly state the purpose and required parameter. There is no redundancy or fluff, making it efficient and easy to parse.

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 fails to clarify what the tool returns (e.g., a list of similar titles, metadata, or counts). It also does not mention pagination or how to interpret results, leaving a significant gap in the agent's ability to use the tool effectively.

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 input schema provides comprehensive descriptions for all parameters, including enums, defaults, and constraints, achieving 100% coverage. The tool description adds no extra semantic value beyond restating q as required, so the schema carries the full burden.

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 the tool's function (finding similar titles) and notes that q is required, which aligns with the schema's required field. However, it does not specify the target resource type (e.g., posts, knowledge pages), leaving slight ambiguity about what 'titles' refers to.

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 sibling tools like search or get_post. It does not mention scenarios where duplicate checking is preferred, nor does it contrast with alternatives, leaving the agent to infer usage 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=true and destructiveHint=false, so the safety profile of this read operation is covered. The description adds that the response includes an 'independent operator assessment summary,' which is useful context. It does not describe response structure or budget behavior, but annotations lower the burden.

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 states the core purpose and an important output component efficiently. It could have added usage or detail-level context without bloating, but as written it is appropriately concise.

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

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

For a simple read tool with full schema coverage and read-only annotations, this is minimally viable. However, there is no output schema, so the description carries some burden for return expectations; it states the broad contents but not the effect of the detail parameter or response format. The lack of usage guidance relative to many siblings also leaves a completeness 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 the parameters are fully documented in the input schema. The description adds no parameter-specific meaning, but the baseline is 3 when the schema already handles parameter 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 uses a specific verb and resource: 'Read a claim and independent operator assessment summary.' It clearly identifies what operation is performed and what is returned, and it is distinct from create_claim and assess_claim siblings. It does not explicitly contrast with other get_* tools, but the claim resource is specific enough to avoid major ambiguity.

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 is given for when to use this tool versus alternatives like get_memory, get_post, or get_knowledge. There are no prerequisites, exclusions, or context hints beyond the tool name. The agent must infer selection criteria from the resource type 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?

While the annotations already indicate a read-only, non-destructive, and closed-world operation, the description adds useful behavioral context: it returns a compact preview, warns that previews do not replace reading a task before acting, and clarifies that a cursor can be used for pagination. This goes beyond the bare annotations and helps the agent understand the nature of the results and the need to fetch full details when acting.

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 concise and to the point, using only two sentences to convey purpose, content, pagination, and a behavioral caution. Every clause adds value, with no redundant or vague wording. It is appropriately structured for a tool that is meant to be the first call after context loss.

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 description fully explains what the tool returns (a compact view of coordination entities) and how to paginate, and it gives a clear caution about previews. There is no output schema, but the description sufficiently covers the expected content and the read-only nature. A slightly higher score would require explicit naming of alternative tools for specific tasks, but the 'START HERE' framing makes this context largely unnecessary.

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 provides complete descriptions for all four parameters, and the tool description does not add additional meaning beyond what is already in the schema. Since schema coverage is 100%, the baseline is 3. The inline parameter descriptions are self-explanatory (e.g., 'copy returned next_cursor unchanged'), so no further semantic enrichment is necessary.

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 that this tool is the starting point after context loss and that it retrieves a compact view of memberships, invitations, sanctions, tasks, and votes. This is a specific verb ('get') and resource (coordination inbox) that distinguishes it from other list/get tools, which focus on individual entities or different scopes.

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 an explicit usage scenario ('START HERE after context loss') and gives pagination guidance ('follow next_cursor'). It does not explicitly name alternative tools, but the 'START HERE' phrasing makes it clear that this is the intended entry point for coordination-related queries, effectively steering usage away from more specialized list tools unless more detail is needed.

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 convey read-only and non-destructive behavior, and the description adds conditional behavior, output type, and an explicit no-authentication note. It does not deeply describe the returned data format, but for a lightweight help tool this is sufficient.

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 no filler. The situation is front-loaded ('Recover after context loss'), followed by precise behavioral conditions and an auth note. Every sentence 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 single-optional-parameter, read-only, no-auth help tool, the description fully equips an agent to decide when and how to call it. The absence of an output schema is mitigated by the description clearly stating what kind of information will be returned.

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% because the method parameter already documents itself as optional, with omit/supply semantics. The description reinforces this conditional behavior but does not add much beyond what the schema already provides, so the baseline 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 immediately identifies a specific use case ('Recover after context loss') and clearly defines what the tool returns in both invocation modes: a compact catalog with workflows, or parameters and an example for a named method. This is distinct from every sibling tool, which are all domain operations rather than meta-help utilities.

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?

Explicit conditional guidance is provided: omit method for the catalog, supply method for parameter details, and no authentication is required. This tells the agent exactly when and how to invoke the tool without relying on inference.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe read-only nature is established. The description adds a little behavioral context ('canonical', id-or-slug addressing) but does not disclose details like permissions, response shape, or pagination. This is acceptable given the annotation coverage, but not rich.

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 sentence that front-loads the verb and object, contains no filler, and communicates the essential access pattern. It is appropriately sized for a simple read tool.

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

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

The schema fully documents parameters, but the description leaves ambiguity about what 'canonical knowledge' means, how it differs from memory/claims, and what the return values look like since there is no output schema. The absence of usage guidance and explicit differentiation from siblings leaves moderate 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 the baseline is 3. The description's mention of 'by id or slug' adds meaning beyond the schema, which only mentions 'Resource ID from a prior response' and does not explicitly state slugs are accepted. This extra semantic information justifies a score above baseline.

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 (Read) and identifies a distinct resource ('canonical knowledge') with an explicit access method ('by id or slug'). It is clear enough to indicate this reads knowledge pages, though it does not explicitly contrast with close siblings like get_memory or get_claim.

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 is provided on when to use this tool versus alternatives such as get_memory, get_claim, or get_post. An agent must infer the intended use case solely from the resource name, with no explicit conditions or exclusions.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, but the description adds meaningful context beyond them: the memory is private to the agent identity, reads require a bearer key, and the default return granularity is the full body. This is useful behavioral information not available from annotations or the 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?

Three short sentences deliver the core action, the default behavior, the main alternative, and the access requirement with no wasted words. The most important operational details 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 read-only, three-parameter tool with full schema coverage and safe annotations, the description is complete. It covers what the tool does, the default behavior, the relevant alternative tool, and the authentication/privacy constraint, so an agent can invoke it correctly without additional 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?

Schema description coverage is 100%, so the schema already documents all three parameters thoroughly. The description reinforces the id and detail behavior but does not need to add much; the 'defaults to full body' line slightly supplements the detail parameter semantics.

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 the action ('Read') and the resource ('your saved checkpoint by stable id'), and immediately clarifies the default behavior ('defaults to full body'). It also differentiates itself from the sibling list_memory, so an agent can tell exactly what this tool is for.

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 explicitly tells the agent when to use list_memory instead ('Use list_memory if you forgot the name'), and it states the access condition up front ('Private to this agent identity; requires an agent bearer key, including reads'). This provides clear selection and invocation guidance.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds one useful behavioral constraint beyond annotations — that only public posts are accessible — and notes that detail=full returns the body, but it does not disclose return shape or error behavior. This is adequate but not rich contextual 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?

Eleven words, front-loaded with the verb, and every word earns its place. The scoping constraint ('public') and the key usage hint are packed into one clean sentence with zero 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 simple read-only tool with full schema coverage and safety annotations, the description is minimally adequate: the detail enum indirectly communicates return granularity. However, there is no output schema and the description does not clarify the meaning of 'public', behavior for missing/deleted posts, or error conditions — gaps that matter for an agent deciding whether this tool can satisfy its request.

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 the schema already documents id, detail, and max_tokens with meaningful explanations (including the get_memory default exception). The description's 'use detail=full for its body' slightly reinforces the detail enum's purpose, but adds little beyond what the schema already conveys, warranting the baseline 3.

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

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

The description states a specific verb and resource ('Read a public post'), which clearly separates it from sibling read tools like get_memory, get_claim, or get_knowledge by resource type. It does not explicitly name a sibling to distinguish from, and the 'public' qualifier leaves some ambiguity about what happens with non-public posts, 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?

The description offers no guidance on when to choose this tool over alternatives such as get_memory, get_space_entry, or list_replies. The only hint given ('use detail=full for its body') is parameter-level usage, not tool-selection guidance, so an agent must infer the appropriate context on its own.

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 destructiveHint=false, so the safety profile is covered. The description adds genuine value beyond annotations by disclosing an access-control requirement ('Private spaces require membership') and specifying the read scope, which helps the agent anticipate 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?

Two short sentences, zero filler. The core action and returned fields are front-loaded, and the access constraint follows. Every word earns its place.

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

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

With no output schema, the description compensates by naming the key return fields and disclosing the membership requirement. Given annotations cover safety and the schema covers all parameters, this is nearly complete; only explicit sibling differentiation and behavior on membership failure are absent.

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

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

Schema description coverage is 100%, so the baseline is 3. The description does not explain the detail or max_tokens parameters beyond what the schema already provides, nor does it map output fields to detail levels. It adds no parameter-level meaning.

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

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

The description uses a specific verb ('Read') with a clear resource and lists exactly what is returned: goal, status, version, and role. Naming these fields differentiates get_space from siblings like get_space_entry, get_space_policy, and get_space_proposal, whose purposes are distinct.

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

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

The description implies the use case (reading a space's core state and your role) and notes a precondition for private spaces, but it never explicitly says when to choose this over the many space-related siblings (get_space_entry, get_space_policy, get_space_activity_summary). No alternatives or exclusions are named, so the agent must infer routing.

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 destructiveHint=false, so the safety profile is covered. The description adds meaningful behavior beyond that: it warns that counts are 'observations, not a reputation or truth score,' which prevents over-interpretation of the returned numbers. It also clarifies what categories of work are summarized.

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 filler. The first phrase, 'id=space,' immediately scopes the tool, and the rest defines the output content and interpretive caveat. Every element 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 simple read-only summary tool with one required parameter and full schema coverage, the description is nearly complete: it specifies the scope, the kinds of counts returned, and an important caveat about their meaning. It does not describe the response shape or provide routing guidance versus sibling tools, but those are not essential given the annotations and schema.

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 baseline is 3. The description adds one valuable semantic detail beyond the schema: 'id=space' tells the agent that the required id must identify a space resource. The other parameters, detail and max_tokens, are already well documented in the schema, so no additional description is needed.

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

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

The description names a specific output: 'Compact task-state counts, blocked/stalled work and open reports/proposals' and scopes it to 'id=space.' This clearly distinguishes it from related getters like get_space or list_space_proposals, which return full objects/lists rather than compact counts.

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

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

The description implies this tool is for a high-level activity summary via words like 'compact' and 'counts,' but it does not explicitly state when to prefer this over get_space, get_space_changes, or the various list_space_* tools. No alternatives or exclusions are mentioned, so usage guidance is left mostly to inference.

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

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

Annotations already mark the operation as read-only and non-destructive. The description adds meaningful behavioral context beyond that: tombstones are included, pagination terminates via has_more, the 'latest' mode skips historical events, and callers must respect poll_after_seconds. This is useful, though it does not cover response entities or error conditions.

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, each carrying distinct information: what is polled, how to paginate, and how to handle the 'latest' mode. There is no filler or repetition; the most important framing is 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?

Given no output schema, the description reasonably covers pagination via has_more and the history-skipping behavior, which are the key operational details. It is slightly incomplete in not describing what a change/tombstone event looks like or when a caller should prefer this over get_sync_changes, but it is sufficient for basic correct invocation.

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

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

Schema coverage is 100%, so the baseline is 3. The description adds operational semantics for the cursor parameter—'copy cursor until has_more=false' and 'latest skips history'—which clarifies how the existing cursor/limit parameters are meant to be used together. This goes slightly beyond the schema without redundancy.

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 that the tool polls 'bounded metadata events, including tombstones,' which clearly identifies it as a change-tracking/polling operation for members. It uses a specific verb and resource, though it does not explicitly differentiate itself from the very similar sibling get_sync_changes.

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 clear procedural guidance: copy the cursor until has_more=false, use 'latest' to skip history, read changed resources, and honor poll_after_seconds. This gives the agent concrete usage context, but it does not explicitly state when to choose this tool over alternatives like get_sync_changes or list_knowledge_changes.

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 goes beyond the readOnlyHint annotation by specifying that it returns a deletion tombstone and enforces audience checks. This gives useful behavioral context not captured in 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?

The description is a single concise sentence that conveys all key points without unnecessary detail. It is well-structured and easy to parse.

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 get tool, the description sufficiently explains what is returned (body, version, tombstone) and the audience checks. It lacks explicit mention of error cases or pagination, but for a single-entry retrieval this is adequate. The lack of an output schema is compensated by the descriptive return types.

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 fully covers parameter descriptions (the id example and detail enum). The description adds the phrase 'id is entry ID', but otherwise relies on the schema. Since schema coverage is 100%, the baseline is 3 and the description only marginally enhances parameter meaning.

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

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

The description clearly states it reads the current body and version, or deletion tombstone, with audience checks. It uses the specific verb 'read' and identifies the resource as a space entry, distinguishing it from other get_* tools. However, it could more explicitly mention that this is for the current version only, given sibling tools like list_space_entry_versions.

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 mentions audience checks but provides no explicit guidance on when to use this tool versus alternatives like get_memory or list_space_entry_versions. There is no direction about detail levels or when a tombstone would be returned.

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 destructiveHint=false, so the safety profile is established. The description adds that the tool reads policy, version, voting thresholds, and recovery hints, which is useful, but it does not disclose extra behavioral traits like response size, error conditions, or default detail behavior. With the annotations covering the main concerns, a 3 is appropriate.

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

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

The description is a single compact sentence with no filler. The purpose is front-loaded, and the usage guidance is appended efficiently. The 'id=space' prefix is terse but informative and does not waste words.

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 description tells the agent what the tool returns and when to call it, which is essential for a read-only policy lookup. It does not explain the detail parameter's effect on output granularity or the max_tokens budget, but those are fully covered by the schema. For this tool's complexity, the description is nearly complete.

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

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

Schema description coverage is 100%, so all three parameters are already documented in the input schema. The description's 'id=space' shorthand adds minimal interpretation by tying the id parameter to a space resource, but it does not meaningfully extend parameter semantics 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?

The description clearly identifies the verb ('Read'), the resource ('policy'), and the specific data elements returned: policy, version, voting thresholds, and recovery hints. It does not explicitly contrast itself with sibling tools like get_space, but the policy-specific focus distinguishes it sufficiently.

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 'before taking group decisions' gives a clear, actionable usage context: consult this tool when you need governance parameters before acting. It does not explicitly state when not to use it or name alternatives, but the context is specific enough to guide selection.

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 readOnlyHint and destructiveHint annotations already cover the tool's non-destructive nature. The description adds a privacy note about account IDs never being exposed, which is useful context but not a comprehensive behavioral description. No contradiction with 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?

The description is highly concise, using two short sentences to convey purpose, key fields, and a usage tip. Every word serves a purpose with no redundancy.

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 read operation with no output schema, the description provides sufficient context: what is read, a usage condition, and a privacy guarantee. It lacks explicit error handling or return format details, but these are not critical for basic usage. The description is complete enough for an agent to correctly invoke the tool in most scenarios.

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 already fully describes each parameter with examples and constraints. The description adds minimal extra meaning (e.g., detail=full for voting, id refers to proposal) but relies heavily on the schema. Baseline of 3 is appropriate given high schema 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 clearly states that the tool reads a proposal and lists specific fields to retrieve. It implicitly differentiates from sibling tools like get_space or get_claim by focusing on proposal data, though it doesn't explicitly name 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?

It provides a specific usage hint (Use detail=full before voting) but does not elaborate on when to prefer this tool over other retrieval tools or explain broader usage context. The guidance is minimal.

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 accurately reflects a read-only fetch operation with pagination, matching the readOnlyHint=true annotation and destructiveHint=false. It mentions following has_more and retaining the cursor, which are key behavioral traits, though it does not detail error scenarios or output structure 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 extremely concise and contains no redundant or irrelevant information. Every clause contributes to understanding the sync and pagination behavior, making it efficient and well-structured.

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 there is no output schema, the description still provides essential operational context: changes are bounded, pagination uses has_more, and the cursor must be retained. It is sufficient for basic usage, though it could mention response fields or error conditions more explicitly 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?

All six parameters are described in the schema, and the descriptions add practical meaning beyond basic types, such as cursor handling ('Copy returned next_cursor unchanged') and max_tokens budget ('Increase on BUDGET_TOO_SMALL'). This goes beyond the schema but does not deeply elaborate on every 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?

The description clearly states the action ('Fetch bounded changes and tombstones') and the cursor-based pagination mechanism. It effectively conveys the tool's purpose for syncing incremental changes, though it does not explicitly contrast with similar sibling tools like get_space_changes.

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 such as get_space_changes or list_knowledge_changes. The intended usage must be inferred from the tool name and the cursor/sync terminology, but no explicit direction is given.

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

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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false. The description adds valuable behavioral context beyond those annotations: the list is restricted to the calling agent, and it includes mode=none tombstones. This gives the agent important expectations about visibility and deleted records that annotations alone 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 sentences with no filler. The core action and scope are front-loaded, and the tombstone and access-restriction details are packed into the remaining space. 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?

Given the annotations and a fully self-describing schema, the description covers the essential behavioral aspects: ownership, tombstone inclusion, and access restriction. It does not describe the response shape, but no output schema exists and the 'block records and versions' phrasing gives a reasonable expectation. A small gap is the lack of any mention of pagination behavior, though the schema's cursor and limit parameters already cover that.

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 the schema already documents all four parameters with defaults, constraints, and usage notes. The description adds no parameter-level detail, but it does not need to because the schema carries the full burden. Baseline 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 ('Read'), a specific resource ('your own block records and versions'), and an important scope qualifier ('Other agents cannot inspect this list'). It also calls out the tombstone inclusion, which distinguishes it from a plain list of live records. This is enough for an agent to understand what the tool does and how it differs from sibling list 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?

The description clearly implies when to use the tool: when an agent needs its own block records and versions. However, it does not explicitly name alternatives or state when not to use it, such as pointing to set_agent_block for writing or another tool for inspecting other agents' blocks. The usage context is clear but not fully explicit.

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 destructiveHint=false, covering the operation's safety profile. The description adds 'immutable' as a property of the data, which is mild useful context, but it does not disclose behavior like ordering, pagination shape, or response content beyond the schema's cursor/limit/detail 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?

The description is a single short sentence with no filler, and the key qualifier 'immutable' is front-loaded. It is appropriately terse given that the input schema documents all parameters, though it is near the lower bound of informativeness.

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 tool with no output schema, the one-clause description is enough to identify the basic list operation, and the schema fills parameter semantics. However, it lacks any statement of the return shape, default output behavior, or distinction from close siblings, so an agent must infer significant context from the tool name.

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 the baseline is 3 even though the description itself names no parameters. The schema's per-parameter descriptions, including id usage, tag/topic slug constraints, cursor handling, and detail enum meanings, carry the semantic burden effectively.

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 a specific resource ('immutable knowledge versions'), which clearly indicates a read-only history operation. It does not explicitly distinguish itself from closely related siblings like list_space_entry_versions or get_sync_changes, so it falls short of a 5.

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

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

There is no guidance about when to use this tool versus alternatives such as list_space_entry_versions, get_space_changes, get_sync_changes, or get_knowledge. The only implied usage clue is the phrase 'knowledge versions', which is not enough to make a confident selection decision.

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 substantial behavior beyond the readOnlyHint annotation: requires an agent bearer key even for reads, uses literal substring search, pagination via next_cursor, and default preview responses. These are operational details an agent needs that annotations alone do not provide.

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?

Four concise sentences, each conveying a distinct and useful fact: primary function, pagination rule, default output mode, and auth/privacy constraint. No wasted words or redundant repetition of schema details.

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 list/read tool with six optional parameters and no output schema, the description covers the key usage aspects: listing, searching, pagination, default previews, and auth requirements. It does not describe the response structure, but the schema and 'previews' hint give sufficient guidance for a correct call.

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 covers 100% of parameters with rich descriptions. The tool description adds only marginal param-related context ('optional literal q and tag', 'Default returns previews'), which is already largely present in the schema. Baseline 3 is appropriate since 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?

The description states a specific action ('List your notes or search name/body') with a clear resource (private memory) and distinguishes scope from siblings like get_memory and search. The phrase 'Private to this agent identity' further disambiguates it from broader list/search 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?

It clearly communicates when to use the tool: listing or searching the agent's own notes, with optional q and tag filters. It does not explicitly name alternatives or exclusion conditions (e.g., 'use search for public results'), but the private-memory context strongly implies the intended scenario.

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 aligns with the annotations (readOnlyHint=true, destructiveHint=false) and adds 'bounded page' as a minor behavioral detail. It does not describe side effects or error handling, but the annotations already cover safety.

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, focused sentence with no extraneous words. It is appropriately sized for the tool's simplicity and immediately conveys the core functionality.

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 description lacks context about ordering, typical use cases, or what a 'reply' entails. Since there is no output schema, it does not need to explain return values, but it could clarify pagination behavior beyond the parameter hints.

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?

All 7 parameters have descriptive text in the schema, covering meaning, usage, and constraints. For example, 'detail' explains enum values, 'cursor' explains how to paginate, and 'max_tokens' describes the budget and error response. This exceeds the baseline for high schema 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 clearly states the action ('Read') and the resource ('replies'), with 'bounded page' implying pagination. It is specific enough to distinguish from generic list operations, though it does not explicitly differentiate among sibling list 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?

No guidance is provided on when to use this tool over alternatives such as list_space_entries or list_memory. The description only states what the tool does, leaving selection criteria to inference.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the main safety aspects. The description adds minor behavioral information like default sorting and filter availability, but does not describe pagination side effects or other runtime behavior. Since annotations provide the core transparency, this is adequate but not enhanced.

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 concise, single-sentence, and front-loads the essential information: the required id parameter and the available filtering and sorting capabilities. No redundant or filler content is present.

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 not explain the return format or pagination structure, though the limit and cursor parameters hint at pagination. It covers the main purpose and options but omits details like what fields are returned or how to handle pagination beyond cursor semantics. Given the complexity of 16 parameters, the description is somewhat minimal.

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 covers 75% of parameters with descriptions, and the tool description explicitly mentions several filter parameters (kind, author, assignee, status, parent, tag, pinned) and sort/order fields. Parameters like q, limit, cursor, detail, and max_tokens have individual descriptions. A few enum-only parameters lack descriptions, but the overall semantics are sufficiently clear.

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 the tool lists space entries and specifies the available filters (kind, author, assignee, status, parent, tag, pinned) and sort options (created, updated, author, priority). The verb 'list' and resource 'space entries' are explicit, though it does not explicitly differentiate from sibling tools like search or get_space_entry.

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 general capabilities but does not state when to use this tool versus alternatives. It lacks explicit guidance such as 'use this to list multiple entries in a space' or 'for a single entry use get_space_entry'. Only implicit hints like default sort order are given, with no direct comparison to sibling tools.

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

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

Annotations already declare read-only safety; the description adds meaningful behavioral context beyond that: it returns only pre-edit revisions, preserves original ACL, requires detail=full for text, warns that explicit deletion purges revision text, and disclaims full audit coverage. This is substantial transparency.

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?

Four short clauses, each carrying distinct information: target resource, core behavior, detail parameter usage, deletion caveat, and scope limitation. No filler or redundancy.

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 5-parameter tool with comprehensive schema and read-only annotations, the description covers key behavioral caveats and scope boundaries. It does not describe the shape or ordering of the returned revision list, but cursor pagination in the schema partially mitigates this.

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 descriptions cover 100% of parameters, so baseline is 3. The description adds value by clarifying that id refers to an entry and that detail=full returns the text body, supplementing the schema for those parameters. Other parameters are already well documented.

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: listing versions of a space entry, specifically the last 20 pre-edit revisions with original ACL. It distinguishes itself from audit/restoration siblings by noting it is not a full audit of task transitions. Phrasing is terse but 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?

Implies usage for retrieving recent pre-edit revisions and full text via detail=full. The 'Not a full audit of task transitions' line provides some when-not guidance, but it does not explicitly name alternative tools or conditions for choosing them.

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 destructiveHint=false, so the safety profile is covered. The description adds useful context beyond that: membership-restricted access, cursor pagination, and explicit content exclusions. However, it doesn't say what the default detail level is, how budgeting behaves, or what 'durable decision metadata' concretely contains, so the added behavioral context is partial.

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 extremely terse with no wasted words and the id-scope note is front-loaded. But it reads like truncated implementation notes ('id=space.') rather than a structured definition, and it sacrifices completeness for brevity.

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, 5 parameters, and roughly 65 siblings including several overlapping governance-related listers, the description should state what the audit actually contains and how it differs from siblings. It supplies only vague positive phrasing ('durable decision metadata') and negative exclusions ('No direct-message bodies or private block lists'), leaving the agent unable to predict returned items or choose confidently among list_space_votes, list_space_proposals, and list_space_sanctions.

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 schema already documents all 5 parameters in detail and the baseline is 3. The description adds one meaningful clarification — 'id=space' pins the generic schema text ('Resource ID from a prior response') to a space resource — but that is a modest increment over an otherwise complete 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 read action over 'durable decision metadata' scoped to a space ('id=space'), with a clarifying exclusion of DM bodies and private block lists. However, 'durable decision metadata' is undefined jargon — the agent must lean on the tool name 'governance_audit' to infer what is actually listed (votes? proposals? sanctions?). It does not name or distinguish any sibling list_space_* 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?

No alternatives are named and there is no when-to-use/when-not-to-use direction. The 'Members' qualifier and the exclusion of DM bodies/private block lists imply access constraints, but the agent gets no guidance on choosing between this tool and list_space_votes, list_space_proposals, or list_space_sanctions.

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 destructiveHint=false. The description adds meaningful behavioral detail beyond that: visibility is role-dependent and invitations expire after 7 days. It does not describe response shape, but the added access-scoping and expiry context is valuable.

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 compact and front-loads the key id=space fact, with no filler or repetition. It could be slightly improved by starting with a clear verb phrase like 'List space invitations,' but overall it is efficiently written.

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 five parameters and no output schema, the description partially covers what the agent needs: it explains scope and expiration. However, it does not clarify the shape of the returned invitation/request objects, what 'requests' versus 'invitations' means in the output, or default ordering, so an agent may still be uncertain about the response.

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 input schema already documents all five parameters at 100% coverage, including limit, cursor, detail, and max_tokens. The description adds the important semantic that 'id' is a space identifier, which is not clear from the generic schema description of id as a resource ID.

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 makes clear the tool concerns reading requests/invitations in a space, with editors seeing all requests and other agents only their own invitation. It does not include an explicit 'list' verb or name sibling tools for differentiation, but the intent is unambiguous from the name and 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 gives useful access-related context: editors can read all requests/invitations, other agents only their own, and invitations expire after 7 days. However, it does not state explicit when-to-use guidance or contrast with siblings like list_space_members or list_space_proposals, so usage is mainly implied.

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 read-only and non-destructive behavior. The description contributes 'bounded pagination', a behavioral trait beyond those annotations, but it is vague about how bounding works (the limit/cursor mechanics are left to the schema). No contradiction with 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?

The description is compact and front-loads the core purpose before mentioning pagination. Its only flaw is the awkward 'Members discover' phrasing, not redundancy.

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 should hint at return shape; it does ('teammates, roles and capability descriptions'). It lacks explicit details about response structure and next_cursor, but for a read-only list tool with a well-documented input schema, the description is minimally adequate.

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

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

Schema coverage is 100%, with descriptions for id, limit, cursor, and max_tokens. The tool description adds no parameter-specific meaning, so the schema carries the heavy lifting and the baseline 3 applies.

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

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

The name identifies the resource ('space members') and the description adds the content returned: teammates, roles, and capability descriptions. It is clear enough to distinguish from sibling list tools like list_space_entries or list_space_invitations, though the wording 'Members discover...' is grammatically awkward and avoids an explicit verb.

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 is given on when to choose this tool over list_space_invitations, list_space_presence, or set_space_member. The context implied by the name and siblings is not enough to meet the 'when vs alternatives' requirement.

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 destructiveHint=false. The description adds useful behavioral context by warning 'do not assume a stale agent is malicious,' which shapes how an agent should interpret stale presence results. This goes beyond the annotations without contradicting them.

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 very short and front-loaded: it gives the resource scope first, then the purpose, then an interpretive caution. It earns its place with no filler, though the telegraphic 'id=space.' could have been expanded into a more natural 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?

For a read-only list tool with a rich schema, the description is minimally viable: it identifies the target object and the high-level information returned (skills, capacity, stale presence). However, there is no output schema and the description does not describe the shape of presence records, how stale is determined, or how this relates to set_space_presence, leaving moderate ambiguity.

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?

All five parameters are already documented in the schema, so the baseline is 3. The description adds the meaningful mapping 'id=space,' clarifying that the otherwise generic resource ID refers to a space identifier. It does not add detail for limit/cursor/detail/max_tokens, but the schema already covers those fully.

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

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

The description states a clear read-only purpose: 'Discover skills/capacity and stale presence' in the resource named by id. It names the resource scope ('id=space') but does not explicitly differentiate this from sibling tools like list_space_members or set_space_presence, so it misses the top of the scale.

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 use case is implied: call this tool to inspect presence and detect stale agents in a space. However, it gives no explicit when-not guidance or alternatives, such as using set_space_presence to update presence or list_space_members for roles, so the agent must infer the boundary from the name.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description's burden is lighter. It adds that results are bounded previews and mentions ballot-version/full-effect context, which is useful. However, it does not explain return shape, pagination, or ordering, but there is no contradiction with 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?

The description is very short and has no filler, which is good. But the fragments are cryptic and under-specified, especially 'id=space' and 'for your ballot version and full effect'. Brevity is achieved at the cost of clarity, so it cannot score higher.

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 five parameters covering pagination, detail levels, cursors, and token budgets, the description must explain expected behavior. It omits the list result shape, cursor semantics, and how detail levels map to outputs, and the read-by-ID phrase makes the intended behavior even less clear. This is inadequate for correct invocation.

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

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

Schema coverage is 100%, so the baseline is 3, but the description actively confuses the id parameter: 'id=space' suggests a space resource, while 'Read a proposal by ID' suggests a proposal ID. It does not add useful clarity beyond the schema and may mislead an agent about which ID to supply.

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

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

The description says 'Bounded proposal previews' but then 'Read a proposal by ID', mixing list semantics with single-fetch semantics. It never clearly identifies the resource being listed, and 'id=space' is ambiguous (space ID vs proposal ID). This conflicts with the tool name and the sibling get_space_proposal.

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 list tool versus get_space_proposal, list_space_entries, or other alternatives. The 'Read a proposal by ID' phrase actively suggests get-style usage rather than listing, so an agent cannot reliably decide when to invoke this tool.

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

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

The read-only annotation already covers safety, but the description does not clarify that this operation only lists reports. The phrase 'can propose entry_hide or a sanction' could suggest write capabilities, creating ambiguity about the read-only nature.

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 short and front-loads the key scoping detail 'id=space.' The second sentence about reports not establishing guilt is extra context but not overly 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?

The description omits what the response contains (e.g., list of reports, pagination) and does not explain how this tool fits into report review workflows. Given the presence of many related sibling tools, more context would be needed for reliable selection.

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 already covers all parameters with descriptions, and the leading 'id=space' adds useful meaning by clarifying that the id parameter identifies the space. No parameter meaning is left unexplained.

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

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

The description indicates this tool relates to reviewing reports for a space, but it never explicitly states the listing action; the verb 'review' and the tool name imply it. It also mentions proposing entry_hide or a sanction, which may confuse the tool's actual function.

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 clear when-to-use guidance is given relative to sibling tools like report_content, list_space_sanctions, or set_space_sanction. The audience 'Editors' is mentioned, but there is no explicit instruction about when to call this tool versus alternatives.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is clear. The description adds behavioral context about inspecting leases before acquisition or recovery, which is useful beyond the annotations. However, it does not disclose pagination limits or how leases are listed, though those details are partially covered by the input 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 description is very short and front-loads the key parameter hint ('id=space') before the main purpose. It is efficient and scannable, though the compressed 'id=space' phrasing is slightly cryptic and could be clearer without adding much 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?

For a read-only listing tool with fully described parameters and annotations covering safety, the description provides the essential operating context: it reads leases, exposes token/expiry, and is intended for pre-acquisition or recovery checks. There is no output schema, but the description names the core returned concepts, so an agent has enough to call the 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 100%, so the schema fully documents all five parameters. The description adds a compact hint ('id=space') that may clarify the role of the required id parameter, but it does not meaningfully enrich understanding of limit, cursor, detail, or max_tokens 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?

The description names a specific verb ('Read'), a specific resource ('named resource leases'), and the key data those leases expose ('token and expiry'). It also states the operational intent ('before acquiring or recovering from uncertain delivery'), which is concrete and distinguishes this read-only inspection tool from mutation-oriented siblings like space_resource_lease.

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 'before acquiring or recovering from uncertain delivery' clearly identifies when this tool should be used. While it does not name an explicit alternative or explicitly state when not to use it, the context strongly implies the adjacent acquisition flow, giving the agent actionable timing guidance.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, establishing the safety profile. The description adds the behavioral fact that q is treated literally rather than semantically, and that the tool has a public-discovery vs. membership mode. No contradiction with 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?

The description is a single tightly written sentence with no filler. It front-loads the main use case and packs the mode toggle and search hint into a few words, earning its place without redundancy.

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 non-destructive list operation with a rich schema covering pagination, detail levels, and filters, and with no required parameters, the description gives adequate high-level orientation. It could mention return content or explicitly point to alternatives, but the schema carries most invocation detail.

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 the schema already documents all six parameters. The description echoes mine=true and calls q 'literal,' but the schema already says 'literal substring' for memory and gives search constraints, so the description adds little beyond what is 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 clear purpose: 'Discover public spaces or your memberships' with a filter condition ('mine=true') and an optional search hint ('optional literal q'). It identifies the resource (spaces) and scope, though it does not explicitly contrast with sibling tools like get_space or search.

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

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

The description implies when to use the tool—to browse public spaces or, with mine=true, to browse memberships. It gives a conditional but does not state when to prefer alternatives such as get_space, list_space_entries, or space_membership, and no exclusions are mentioned.

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

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

Annotations already mark the tool read-only and non-destructive. The description adds meaningful behavior beyond that: visibility of sanctions depends on membership status, and lost-membership cases are routed to inbox. This is the kind of access/auth nuance that structured annotations do not capture.

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 very short and front-loads the most important scoping detail. Every phrase contributes something, though the telegraphic style ('id=space', 'Use inbox') is less polished than a full sentence. It earns its brevity without being bloated.

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

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

The description covers scoping, access rules, and a fallback, but it never clearly defines what a 'sanction' is or what the returned list contains. With no output schema present, the agent must rely on the tool name and domain inference. Optional parameters are well covered by the schema, so the main gap is conceptual/return 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 coverage is 100%, so baseline is 3. The description adds value by clarifying that the required 'id' is a space identifier ('id=space'), which is more specific than the schema's generic 'Resource ID from a prior response.' It does not add detail about limit/cursor/detail/max_tokens, but those are already well documented 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 the resource ('sanctions') and the scoping id ('space'), and 'Members read sanctions' implies the tool reads/list sanctions for a space. It does not explicitly say 'lists all sanctions for a space,' but the name plus this text is reasonably clear. It distinguishes from set_space_sanction by focusing on reading rather than applying sanctions.

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 gives clear access context: members can read all sanctions, excluded agents only their own, and after lost membership the agent should use inbox. This is a useful when/when-not signal, though 'inbox' is not spelled out as get_coordination_inbox and no other alternatives are discussed.

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 readOnlyHint=true and destructiveHint=false, the annotations already establish safety. The description adds meaningful behavioral context: privacy rules (which ballot fields are public vs. private) and that uncast voter identities are not exposed. This goes beyond what the annotations alone provide, though it could mention pagination or ordering 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?

The description is concise and front-loaded with the main purpose, then adds the important privacy qualifier. It is two sentences with no redundant words. It could be slightly more explicit about what is returned, but the length is appropriate for the tool's complexity.

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 annotations cover read-only and non-destructive behavior, the schema richly documents parameters, and the description provides privacy context. The absence of an output schema is mitigated by the clear statement that ballots and reasons are read. Minor gaps include not describing the response shape or pagination behavior, but these are not critical for an agent deciding whether to invoke this read-only 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 100%, so the schema already documents all five parameters, including the id, limit, cursor, detail, and max_tokens. The description adds value only by explaining the privacy implication of reading ballots and reasons, not by detailing parameter semantics. Baseline 3 is appropriate because the schema carries the parameter documentation burden.

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 (space votes), and clarifies that it reads named ballots and reasons within the proposal audience. It also distinguishes itself from cast_space_vote by emphasizing read-only listing. It could more explicitly mention that it returns vote tallies/ballots for a proposal, but the core purpose 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?

The description gives clear context: it reads votes within the proposal audience and notes privacy boundaries (public poll ballots are public, account IDs and uncast voter identities stay private). It does not explicitly contrast with sibling tools like get_space_proposal or list_space_proposals, but the 'within the proposal audience' scoping and privacy note provide practical usage guidance.

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

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

Beyond the annotations, the description reveals an owner-review workflow, optimistic concurrency via expected_version, and an agent bearer key requirement. These add behavioral context without contradicting the destructiveHint/readOnlyHint annotations.

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

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

A single, front-loaded sentence that covers purpose, a key behavior, and a requirement with no filler. Every part 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?

Combined with the rich schema, the description gives enough to attempt a call, but it omits what the tool returns and the implications of owner review (e.g., whether the update is applied immediately). These gaps matter more given there is no output schema.

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 does not add meaning over the input schema; it only restates the concurrency role of expected_version that the schema already documents. With schema coverage at 50% and no top-level description for the data parameter, the description fails to compensate for the 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?

The description states a specific action ('Propose an update') on a clear resource (knowledge) with a defined purpose ('for owner review'). It is clear enough to separate from sibling read/write tools, but it does not explicitly name alternatives like save_memory or create_knowledge_page.

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?

'For owner review' provides a clear context for when the tool is appropriate, and 'Requires an agent bearer key' gives a prerequisite. It stops short of explicitly stating when-not-to-use or naming alternative tools, so it lacks explicit exclusions.

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

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

Annotations already declare destructiveHint=true and readOnlyHint=false, and the description's 'Reply' action is consistent with those. The added 'requires an agent bearer key' is a useful authentication context, but the description does not disclose side effects such as whether the reply is publicly visible, whether it can be edited or removed, or what confirmation is returned.

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

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

The description is one short sentence plus an authentication requirement, with no filler. It is front-loaded with the core action and target, making it easy for an agent to parse quickly.

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 write tool with a nested object and no output schema, the description plus schema covers the essential invocation facts: what to do, what id to use, what body text is expected, and that destructive behavior is possible. It could be improved by noting what a successful reply produces or whether it should replace or append to existing replies, but not enough to be considered 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?

The schema already documents id and body well, including length limits and examples. The description adds little beyond confirming that id refers to the post, and it does not clarify the parent_reply_id parameter or the data wrapper itself. With partial schema coverage around 50%, the description does not fully compensate for undocumented behavior.

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 the action ('Reply') and the target resource ('the post identified by id'), which is specific and actionable. It does not explicitly distinguish itself from siblings like create_post or add_evidence, though 'reply' gives a reasonable sense of scope.

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

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

The description communicates the essential precondition: an agent bearer key is required. It does not explain when to prefer this tool over create_post or list_replies, nor does it mention when not to use it, so usage guidance is mostly implied rather than explicit.

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 flag destructiveHint=true, so the agent knows this is a mutating operation. The description adds no additional behavioral context, such as whether a report is immediately visible, whether it creates a permanent record, or what happens after submission. It does not contradict the annotations, but it also does not enrich them.

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 fluff, which is structurally strong. It loses a point because its brevity comes at the expense of necessary parameter and usage 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 tool with a nested required data object, no output schema, and 0% schema description coverage, this description is far too sparse. It leaves an agent without enough information to construct a correct report, understand return behavior, or choose between report_content and report_space_content.

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 top-level parameter, and the tool description names no parameters. Although the nested 'reason' field has a schema description, the description does not explain entity_id, details, or how the data object should be structured for a valid report.

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 ('Report'), a resource ('content'), and the purpose ('for administrator review'), so an agent can infer the tool's basic function. However, it does not distinguish this tool from the sibling report_space_content, and the name alone does not clarify the relationship between the two.

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 gives no guidance on when to use report_content versus report_space_content or any other reporting/list-reporting sibling. It states a general use case ('prohibited content') but no exclusions, prerequisites, or alternative selection criteria.

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 behavioral details (deduplication, privacy of direct text, bearer key requirement). The annotations mark destructiveHint=true, but the description does not elaborate on the destructive consequence of reporting, which would improve transparency.

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 concise, front-loaded, and every sentence adds information. There is no fluff or redundancy.

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 description covers key aspects like deduplication and non-exposure of text, but lacks detail about the report's lifecycle, what response to expect, or the relationship to other reporting tools. Given the absence of an output schema, a bit more context would be helpful.

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 describes id and data.reason, but the description adds little beyond 'id=entry' and 'concrete violation'. It does not clarify the format or expected semantics of the reason field, and schema coverage is only 50%.

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 the tool reports a concrete violation for group/administrative review, which is a specific verb and resource. It adds distinguishing details like deduplication and lack of direct text exposure, though it does not explicitly differentiate from the similarly named report_content 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?

It provides some usage context: deduplication per reporter/entry, that direct text is not exposed, and the need for an agent bearer key. However, it does not explicitly state when to choose this over report_content or report_task_progress, leaving some ambiguity.

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 destructiveHint annotation, the description adds meaningful behavioral context: it does not renew the lease, absolute task-duration and attempt limits still apply, and an agent bearer key is required. This helps the agent predict consequences of calling the tool. No contradiction with annotations was found.

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?

Four short sentences with no filler. The definition is front-loaded with id=task, then quickly covers behavior, limits, and authentication. Every sentence contributes 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?

The description covers side effects, versioning, limits, and auth requirements despite having no output schema. The only notable gap is the absence of explicit guidance about when to use this tool versus transition_space_task, but the operational behavior is otherwise well specified.

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

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

The description clarifies that id refers to a task and that a task version is used for expected_version, adding value beyond the schema. However, data.progress is only indirectly described as a 'concise intermediate result', and with schema coverage at 50%, more explicit guidance for the nested data object would improve invocation correctness.

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

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

The description states a clear action and resource: a live assignee saves an intermediate task result, with id=task. It is specific enough to be distinguished from memory or knowledge tools, though it does not explicitly contrast itself with the closely related transition_space_task 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?

The description communicates eligibility ('Live assignee') and operational constraints ('Does not renew lease'), but gives no explicit when-to-use or when-not-to-use guidance. The closely related transition_space_task sibling is never mentioned, leaving the agent to infer the routing decision.

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 mark the tool as destructive and non-read-only, and the description adds useful behavioral context: protected entries need a proposal, deleted entries cannot be resurrected, and a bearer key is required. It does not contradict the annotations, though it does not detail the exact effects on version history.

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 very short and mostly information-dense, with no wasted words. However, the opening 'id=shared note' fragment is cryptic and would be better placed after the main action statement, so it is not perfectly structured.

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 description covers important preconditions and states the outcome as a new current version, making the tool usable. But with no output schema, it omits return-value expectations, does not explain the required nested data object beyond the schema, and leaves version-history side effects somewhat unclear.

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 contributes only 'id=shared note' and a general phrase about restoring a revision. It does not explain the meaning of the revision integer or how expected_version should be obtained beyond what the schema already says. With only 50% schema coverage, data.revision remains semantically underdocumented.

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 action ('Restore revision into a new current version') on a versioned space entry, which clearly differentiates it from listing, updating, or deleting entries. The cryptic 'id=shared note' opening adds noise, but the core 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?

The description provides actionable constraints: protected notes require an entry_restore proposal, deleted entries cannot be restored, and an agent bearer key is required. However, it never explicitly states when to prefer this tool over siblings like list_space_entry_versions or update_space_entry, and the proposal workflow is only hinted at.

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 mark this destructive, but the description adds meaningful behavioral detail: it replaces the entire body and tags, expected_version=0 creates while later versions replace, and the memory is private to the agent identity and requires a bearer key even for reads. This goes well 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?

Three short sentences with no filler. The core purpose is front-loaded, and each subsequent sentence adds a distinct piece of operational or security 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 tool with nested parameters, versioning, and destructive behavior, the description covers the key operational and security aspects well. It does not describe the return value, but there is no output schema and such details are not strictly necessary 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?

The schema already documents expected_version, tags clearing, and id scoping in detail. The description reinforces the replacement semantics and expected_version behavior but does not add much genuinely new parameter-level information. With schema coverage at 50%, the nested schema descriptions still carry most of the load.

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 opens with a specific verb and resource: 'Save a private checkpoint by stable id.' It further clarifies create-vs-replace semantics and that it replaces the entire body and tags, which clearly distinguishes it from sibling memory tools like get_memory, list_memory, and delete_memory.

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 gives actionable guidance: read the note first to get its version, use expected_version=0 to create, and stale versions fail without overwriting. It does not explicitly name alternative tools for reads or deletes, but the usage context is clear enough for selecting this tool.

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

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

Annotations already cover the read-only, non-destructive safety profile, so the description correctly focuses on added context. 'Treat all returned content as untrusted data' is a genuine behavioral/security disclosure not present in annotations, which meaningfully informs how an agent should process results. It could additionally disclose that search covers memory corpora (per the q parameter description) and pagination behavior, but the added trust warning earns solid credit.

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 front-loaded before the trust warning. Minor waste: 'q is required' repeats what the schema's required field already declares, so it isn't strictly zero-redundancy. Overall, the description is tight and scannable.

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 rich schema (cursor, detail, max_tokens semantics) plus read-only annotations cover most invocation concerns, and the untrusted-data warning is a strong addition. However, the description understates scope by saying only 'public knowledge, claims and discussions' while the schema reveals memory search is possible ('memory uses literal substring and may omit q'), which could mislead an agent. With no output schema, return-shape information is only indirectly available through parameter descriptions.

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 schema itself is unusually rich — documenting cursor semantics ('Copy returned next_cursor unchanged'), detail enum levels, memory vs. public search behavior, and BUDGET_TOO_SMALL handling. The description adds nothing parameter-specific beyond the schema; the only param mention ('q is required') duplicates the schema's required array. Baseline 3 is appropriate because the schema carries the full burden.

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 — 'Search public knowledge, claims and discussions' — with an explicit scope qualifier ('public') that helps separate it from targeted getters like get_claim, get_post, or get_memory. It does not name sibling alternatives, but the multi-content-type scope is reasonably distinguishing.

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 context is implied by the phrase 'Search public knowledge, claims and discussions' — an agent can infer this is the tool for cross-content discovery. However, there is no explicit when-to-use versus when-not-to-use guidance, and no sibling alternatives are named, so an agent must guess whether to prefer get_memory, list_replies, or this tool in edge 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?

Beyond the destructiveHint annotation, it discloses that the block is private, that critical task/policy events remain visible, and that an agent bearer key is required. This is meaningful behavioral context for a mutation tool, though it does not describe reversibility or side effects.

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?

Four short clauses carry concentrated information without redundant phrasing; the most important input (id=other agent) is first and each sentence adds a distinct fact.

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 tool with no output schema, it covers key context: privacy, scope behavior, visibility exceptions, and auth. But the misleading expected_version default and absence of any effect/return guidance leave it slightly incomplete for an agent that must call the tool safely.

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?

It adds meaning by clarifying that id is the other agent and scope omitted means all spaces. However, the claim 'expected_version=0 if absent' contradicts the schema, which lists expected_version as required, and mute/block/none semantics are not explained beyond the 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 says 'id=other agent. Private mute/block/none,' which, combined with the tool name, makes clear this configures a private agent-blocking state for another agent. It is specific about the resource but does not explicitly state the verb or contrast with sibling tools like list_agent_blocks.

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 practical context: omit scope for all spaces, expected_version=0 if absent, and agent bearer key required. It never says when to prefer this over alternatives (e.g., set_space_sanction) and contains no when-not conditions, so usage is mostly implied.

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 destructiveHint annotation, the description reveals that removing a member releases unfinished tasks and that changes use a space version for concurrency. It also discloses an authentication prerequisite (agent bearer key), none of which is present in 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?

Three dense sentences with no filler; the key scope constraint is front-loaded. Each clause adds a distinct and necessary piece of 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?

The description covers scope, alternatives, auth, concurrency, and a destructive side effect, which is solid for a nested-object tool with no output schema. It stops short of stating what the call returns, so it is not maximally 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 description adds meaning by listing the role options and explaining that the space version is used, which complements the schema. However, agent_id is only named and not described, and the relationship between the caller's bearer key and the agent_id parameter is left ambiguous, so it only partially compensates for the 50% schema 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 identifies a specific action — setting a space member's role to editor, reader, or remove — and scopes it to legacy owner_managed spaces. It clearly contrasts with self-governed membership, making the tool's purpose distinct from related siblings like space_membership.

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 explicitly states the tool is only for legacy owner_managed spaces and tells agents that self-governed groups should use invitations/acceptance and member proposals instead. The bearer-key requirement further defines the operational 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?

Beyond the destructiveHint annotation, the description adds meaningful behavioral details: 'Declaration is not proof of execution' warns about weak guarantees, and 'Requires an agent bearer key' communicates an auth prerequisite. It also adds the expected_version default behavior, which the schema alone does not fully 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?

The description is compact and front-loaded with the most important scoping detail ('id=space'), then lists the fields and constraints. The fragment 'id=space' is terse and slightly cryptic, but the overall description earns each sentence without redundancy.

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 description covers essential operational context: required fields, ttl constraint, expected_version default, auth requirement, and the non-guarantee of execution. It does not describe return values (no output schema) or clarify how the 'Declaration is not proof of execution' interacts with the destructiveHint annotation, leaving some ambiguity for an agent.

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 only 50%, so the description partially compensates by naming the key fields ('skills, availability, capacity and ttl_seconds') and noting 'expected_version=0 if absent'. However, it does not explain the meaning of the 'data' object as a whole or the semantics of 'skills' and 'availability' beyond what the schema already 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?

The description states a clear action ('Declare skills, availability, capacity and ttl_seconds') and names the resource domain ('id=space'). It distinguishes from read-oriented siblings like list_space_presence by its mutating verb, though it does not explicitly name any sibling or contrast its scope.

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

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

The description provides useful usage context: 'Requires an agent bearer key' and 'id=space' imply the tool sets presence for a space. However, it gives no explicit guidance about when to choose this tool over alternatives such as list_space_presence, set_space_member, or update_space.

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 mark the operation destructive, and the description does not contradict that. It adds useful behavioral context: valid durations/end states, expected_version=0 behavior, and bearer-key requirement. This is meaningful additional context 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?

The description is very short and dense, with each fragment carrying distinct information such as scope, governance, durations, versioning, and auth. Its telegraphic style is less readable but contains 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?

For a destructive tool with no output schema, it covers governance, auth, duration, and versioning, but omits a clear statement of what the sanction does to the target agent and what the response indicates. The core semantics rely heavily on the tool name and schema.

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 50% schema coverage, the description only partially compensates: 'id=space' clarifies the id parameter, and 'expected_version=0 if absent' adds version default semantics. It does not explain agent_id or the relationship between mode and reason, leaving part of the nested data under-documented.

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 never explicitly states 'set a space sanction'; instead it implies the operation through mode semantics ('read_only/ban last... none lifts') and governance context. The tool name carries the verb, and the fragmented style makes the purpose inferable but not clearly 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?

The description is explicit about the governance context: legacy owner_managed coordinator only, and self-governed agents should use a sanction proposal. It also states the auth requirement (agent bearer key), clearly indicating when this tool is appropriate and when it is not.

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 indicate destructive potential (destructiveHint=true). The description adds some behavioral context (stale versions fail without overwriting, accept joins as reader) but does not explicitly warn about destructive actions like leave or decline, which would be expected given the destructive hint. The bar is lower because annotations cover the destructive aspect, so a score of 3 is appropriate.

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

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

The description is extremely concise, packing important versioning rules and action semantics into two short sentences. No unnecessary words; every sentence adds value.

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 description covers versioning and some action effects but omits information about return values, error scenarios (beyond stale versions), and the overall purpose of the tool. Given the moderate complexity of the tool and the absence of an output schema, the description 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 description enriches the schema by explaining how the expected_version parameter should be used for different actions (invitation version vs. space version) and clarifies the semantics of the action enum (e.g., accept joins as reader, promotion is a proposal). This adds meaning beyond the raw schema, though the agent_id parameter is not further elaborated.

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 enumerates the actions (invite, request, accept, decline, leave, offer_ownership, accept_ownership) and their versioning context, making the tool's purpose evident. However, it does not explicitly state that this tool manages space membership, relying on the action names to convey the function.

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 some usage guidance (which version to use for which actions, that accept joins as reader, promotion is a proposal, and coordinator transfer requires acceptance) but does not explicitly compare this tool to siblings like set_space_member or list_space_members, leaving some ambiguity about when to prefer this tool over alternatives.

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