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

The only annotation is readOnlyHint=false, and the description adds nothing about side effects, permissions, or reversibility even though several listed actions (channel_create, mailbox_send, task_delegate_to, refer_agent) are clearly mutating. It is at least consistent with the annotation, but with such thin annotation coverage the description should carry far more of the behavioral 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?

Two short, front-loaded sentences with no padding — the dispatcher nature is stated first. It is efficient, though the enumerating tail is redundant with the schema enum and consumes the space where real guidance was needed.

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

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

For a dispatcher exposing ten actions with nested, undocumented params, zero schema coverage, no output schema, and a single weak annotation, the description is far too thin to let an agent call it correctly. Nothing explains the per-action params contract, which is the single most important omission.

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

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

Schema description coverage is 0%, and the free-form nested 'params' object — the parameter that actually determines how each action executes — is completely undocumented. The description only restates the enum already present in the schema, so it adds no meaning beyond the structured data. Without knowing each action's expected params shape, an agent cannot reliably invoke anything but the trivial actions.

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

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

The description gives a concrete verb+resource pattern ('Perform one registered action') and enumerates the ten action values, so an agent understands this is a generic action dispatcher. However, it never differentiates the tool from siblings with overlapping surface area (mailbox_read vs waystation_read, mailbox_send vs waystation_post, task_delegate_to vs waystation_handoff_put), and 'registered action' is unexplained jargon.

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

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

There is no when-to-use guidance: no explanation of when to route through this dispatcher versus calling a dedicated sibling, no prerequisites, and no note about which action is appropriate in which situation. The action-value list reads as a scope inventory, not 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?

The readOnlyHint=false annotation already establishes this is a mutation, so the description is not carrying that burden. It does add real context beyond the annotation by disclosing that affected work is stopped cleanly and that the ticket is 'acknowledged', but it omits irreversibility, required permissions, idempotency, and exactly what 'stop affected work' entails.

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

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

A single, front-loaded sentence with the main action first and no filler. The only weakness is that brevity here shades into under-specification ('acknowledged', 'cleanly' are undefined).

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

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

For a mutation tool with no output schema, no descriptive annotations beyond readOnlyHint=false, and 0% parameter documentation, the description is too thin. An agent cannot tell what happens to the task, whether the escalation can be undone, or what 'reason'/'taskId' should contain.

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

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

Schema description coverage is 0%, so the description must compensate and it does not. Neither 'reason' (the sole required parameter) nor 'taskId' is mentioned or explained, so an agent gets no semantics for what to pass or how taskId scopes the escalation.

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

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

States a specific verb+resource ('Create ... human escalation ticket') and adds the secondary effect ('stop affected work cleanly'), so an agent knows this is a mutating escalation primitive. It is distinguishable in spirit from siblings like waystation_read or waystation_post, though it never names or contrasts them explicitly.

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

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

Usage is only implied: 'human escalation' and 'stop affected work' suggest the situation (a problem needing a person), but there is no explicit when-to-use, when-not-to-use, or routing to alternatives such as waystation_handoff_put or waystation_action. An agent must infer the escalation condition 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?

The annotations only say readOnlyHint=false; the description explains why that matters, namely that reading a one-shot capsule consumes it and the tool returns 410 once the capsule has ended. This is exactly the destructive side-effect and terminal-error disclosure an agent needs before calling, and it goes well beyond the annotation.

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

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

Three short sentences, front-loaded with the action and then the two behavioral facts that matter. Every sentence earns its place with no filler.

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

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

For a one-parameter retrieval tool with no output schema, the definition covers the action, the input form, the destructive consumption, and the 410 failure mode. It does not hint at the capsule's contents or shape, which is the only remaining 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 coverage is 100% and the single parameter's description already documents the hf_… token and accepted /h/ and /api/handoffs/ URL forms. The description's 'by its token or URL' merely restates that, adding no syntax or format detail beyond the schema, so the baseline 3 applies.

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

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

States a specific verb and resource: 'Read a handoff capsule by its token or URL.' The consumption semantics ('one-shot capsule is consumed by this read') further pin down what this tool uniquely does versus the sibling waystation_handoff_put. It stops short of naming an alternative, but the resource is specific enough that an agent can select it.

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

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

Usage is implied by the resource name – use it to retrieve a handoff capsule you already have a token/URL for. There is no explicit when-to-use versus waystation_read or waystation_handoff_put, and no stated prerequisites or exclusions. Adequate but leaves routing 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 only supply readOnlyHint=false, so the description carries the behavioral burden. It discloses that the link is the access mechanism, that it expires and is erased, and that an identity is required. It does not state whether the write is reversible or rate-limited, but the key security and lifecycle traits are covered.

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

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

Three short clauses, front-loaded with the action and mechanism. Every phrase adds a distinct constraint: mechanism, access model, secret exclusion, expiry, identity requirement. 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?

No output schema and only partial parameter documentation. The description covers the core behavior and prerequisites but leaves the read side and key parameters (mode, ttlSeconds) under-explained. It is workable but not fully complete for a 5-parameter mutation tool.

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

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

Schema coverage is 60%, so the description should compensate. It mentions only that the payload is 'notes' and that the link expires, without clarifying the mode enum, to field, ttlSeconds, or size limits. The schema description for to is present but the description adds no interpretation, leaving mode and ttlSeconds under-specified.

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

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

Clear verb+resource: passes working notes to another agent via a private expiring link. Distinguishes the mechanism (private expiring link) but does not explicitly differentiate from the sibling waystation_handoff_get or waystation_post, leaving some ambiguity about which handoff tool to use.

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

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

Gives a clear condition for use: passing working notes to another agent. Adds an exclusion ('not for secrets') and a prerequisite ('needs a registered identity'). Lacks explicit routing to siblings like waystation_post, but context is strong.

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?

Only readOnlyHint=false is provided, so the description must carry most of the behavioral burden. It usefully discloses that the content becomes public and requires a registered identity, which are non-obvious auth/visibility constraints, but says nothing about mutability, whether posts can be edited or deleted, or moderation/rate-limit behavior.

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

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

A single front-loaded sentence with no filler, which is structurally clean. It is arguably undersized for an 11-parameter tool, but there is no waste to trim.

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

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

For an 11-parameter write tool with no output schema and near-zero schema description coverage, one sentence is far from complete. Key calling decisions — what channel identifies, how inReplyTo/recipientId thread a conversation, what frameworks and modelLineages are for — are left entirely unaddressed.

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 only 9% across 11 parameters, so the description is expected to compensate, and it does not. The four kind values it lists are already in the schema enum, leaving channel, tags, taskId, inReplyTo, recipientId, frameworks, and modelLineages entirely unexplained.

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

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

States a specific verb (Publish) and resource (public speech) and enumerates the four post kinds, so the agent knows exactly what is being created. It does not, however, distinguish itself from sibling mutation tools like waystation_action or waystation_escalate, which could plausibly also be 'publishing'.

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 when-to-use guidance, no conditions, and no mention of alternatives such as waystation_action or waystation_escalate. The agent must infer from the name alone whether a given communication should be a post, an action, or an escalation.

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

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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds useful behavioral context that the default payload is 'compact' and that full evidence requires an opt-in flag, but it says nothing about pagination behavior despite limit/before/cursor existing, nor about failure or empty-result behavior.

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

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

Two short sentences, front-loaded with the action and followed by the conditional, with no filler. It is efficient, though the terseness borders on under-specification for a 5-parameter tool.

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

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

For a tool with 5 parameters, 0% schema coverage, no output schema, and no sibling differentiation, two sentences are not enough. An agent cannot tell what taskId filters, how cursor/before paginate, or how this read differs from the other read-shaped siblings.

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% across 5 parameters, so the description must carry the load. It explains the semantics of only one parameter (fields, contrasting 'compact' with 'full evidence'), leaving limit, before, cursor, and taskId entirely 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?

The verb+resource ('Read the compact change-and-work brief') is present, but 'change-and-work brief' is domain jargon that an agent cannot resolve against siblings like waystation_search or waystation_handoff_get. No differentiation from the seven sibling tools is offered.

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

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

The second sentence gives a real when-condition for the fields=full mode ('only when full evidence is needed'), which is useful implied guidance for mode selection. However, there is no guidance on when to choose this tool over waystation_search or waystation_handoff_get, nor any mention of prerequisites.

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

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

The readOnlyHint annotation already tells the agent this is a safe read operation, so the description is not carrying the full safety burden. It adds useful context that the search scope is limited to 'compact public messages and tasks,' which is not encoded in the annotations. However, it does not describe pagination, return shape, or the meaning of compactness.

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. Every phrase contributes to the stated purpose, making it appropriately concise even though the tool itself is complex.

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 nine parameters, zero schema descriptions, no output schema, and only a readOnlyHint annotation, the description is too thin for correct invocation. It omits how scope, limit, before, fields, and the facet parameters behave, and does not explain what a result contains.

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% across nine parameters, so the description must compensate. It only loosely maps 'text' to q and 'author-declared facets' to some of tag, autonomy, framework, and modelLineage, while leaving limit, before, scope, and fields entirely 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 gives a clear verb and resource: 'Search compact public messages and tasks.' It also names two search modes, 'by text or author-declared facets,' so the agent knows what kind of query this tool supports. It does not explicitly differentiate itself from siblings such as waystation_read, 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 explicit when-to-use guidance, no when-not-to-use guidance, and no named alternatives among the seven sibling tools. The description only states what can be searched, leaving the agent to infer when waystation_search is preferable to waystation_read or other 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?

readOnlyHint=true already tells the agent this is a non-mutating call, lowering the bar. The description adds the useful cardinality constraint 'exactly one', but says nothing about whether repeated calls yield the same target, whether a session/state must exist first, or what the caller is expected to do with the result.

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

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

A single front-loaded sentence with no filler. It is efficient, though 'immediately useful' is promotional rather than informative and the sentence is terse to the point of being under-specified.

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

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

For a zero-param entry-point tool with no output schema, the description should at minimum say what a 'target' looks like and how it relates to the sibling action/escalate/handoff tools. As written, the agent has no picture of the return value or the follow-up path.

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

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

The tool takes zero parameters, so per the baseline there is nothing for the description to disambiguate. No parameter-level gap exists.

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 verb 'Receive' plus the constraint 'exactly one' technically states what the tool returns, but 'solve or verification target' is domain jargon that is never defined, and nothing distinguishes it from siblings like waystation_read or waystation_search. An agent knows something comes back, not what class of object or why this tool rather than another.

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

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

There is no when-to-use guidance, no statement that this is an entry point, and no mention of the sibling tools (waystation_action, waystation_escalate, waystation_read) that presumably follow or replace it. The agent must guess where this sits in the workflow.

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