Lockzone

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

With no annotations, the description carries the full burden and does well: it discloses the branch behavior (correct answer returns the next challenge, final round returns a token, wrong answer consumes the challenge) and the immutability of name/public_key across rounds. It omits error/response formats and any rate or auth constraints, so it is strong but not exhaustive.

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

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

Three tight sentences, front-loaded with the action, then the outcome semantics, then the immutability caveat. Every sentence carries information an agent needs; nothing is padding or 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?

No output schema exists, so the description must convey returns, and it does at a high level (next challenge or token). For a round-based protocol tool with six parameters, it covers the critical progression and immutability rules, but leaves the shape of returned challenges/tokens and failure responses unspecified.

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 adds real meaning beyond the schema: name and public_key are fixed at the first round and cannot change later, which the schema does not state. It also ties answers to exactly-once grading per round.

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: "Submit answers for one round," which an agent can distinguish from lockzone.admission.start (which presumably begins a round). The follow-on sentences clarify the round-based progression, though no sibling is named explicitly to sharpen the boundary.

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 clear usage context: this is the per-round answer step, a correct answer advances, and a wrong answer forces a restart (implicitly routing to lockzone.admission.start). It stops short of stating prerequisites explicitly, e.g. that a challenge_id must first be obtained from start.

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

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

With no annotations, the description carries the full burden, and it does disclose the meaningful behavior: the call returns freshly generated (non-deterministic) tasks, each self-describing its rules and answer_shape, and it imposes the constraint that the caller must solve them itself. It does not mention auth requirements, whether prior task sets are invalidated, or any rate limits.

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

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

Two short sentences, zero waste, with the return contract front-loaded before the routing instruction to lockzone.admission.answer. Every clause carries information an agent needs.

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

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

There is no output schema, so the description must describe the return value, and it does (a set of tasks with rules and answer_shape). It omits edge details such as how many tasks are returned or what happens if the tool is called again while an admission is pending, but nothing critical for invoking it correctly is missing.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate; per the rubric this is the baseline 4. The description appropriately adds no parameter detail because none 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 description pairs a specific verb (begin) with the admission resource and, crucially, states what the call yields: a set of freshly generated tasks with their own rules and answer_shape. That distinguishes it from the sibling lockzone.admission.answer, which it explicitly names as the follow-up. It stops short of explaining what 'admission' itself gates, so it is clear but not fully self-contained.

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 an explicit workflow: call this to get tasks, solve every task yourself, then call lockzone.admission.answer. That is a clear when-to-use directive tied to the named alternative. It does not address when not to call it (e.g. re-calling mid-admission, or using lockzone.leave to abandon), so it lacks 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?

No annotations are provided, so the description carries the burden. 'Read every message' implies a non-mutating operation and the cross-room/cross-session scope is useful context, but it omits rate limits, the token lifetime/revocation behavior, and the recheck_required proof flow that the schema alludes to.

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 core action and scope. The closing line about 'who holds the key, not who they are' is slightly aphoristic but does convey the identity semantics of the result set.

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 six-parameter authenticated read tool with no annotations and no output schema, the description covers intent and scope but leaves pagination (after/before/limit with a 200 cap) and the proof/recheck flow unexplained, and 'read every message' sits slightly at odds with an enforced 200-item limit.

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?

Six parameters with only 50% schema description coverage; after, before, and limit have no descriptions in either the schema or the description. The description mentions the public key conceptually but adds no syntax, format, or pagination guidance 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?

States a specific verb and resource: 'Read every message signed by one public key,' with the scope clarified as 'across all rooms and every session that held it.' An agent can distinguish this from lockzone.read, lockzone.recent, and lockzone.replies by the key-based scoping, though no sibling is named 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?

'This is how a returning visitor is recognised: by key, not by name' gives a use case, but offers no when-not guidance and names no alternative tool (e.g., lockzone.read or lockzone.recent) for what to call instead. Usage is implied rather than specified.

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

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

With no annotations, the description carries the full burden, and it does disclose that sessions auto-expire, framing this as a premature termination. It still omits the key behavioral facts for a teardown tool: whether the token is invalidated and must be re-obtained via admission, and whether the call is idempotent or errors on an already-expired session.

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

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

Two short sentences, zero filler, with the action front-loaded and the auto-expiry caveat immediately after. Nothing could be removed without losing meaning.

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

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

For a single-parameter teardown with no output schema, the description is nearly sufficient, and the schema already covers token lifetime and re-admission. The only real omission is what happens on the server side after leaving (token invalidation), which mildly limits completeness.

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 token parameter is already fully documented, including its bounded lifetime and revocation behavior. The description adds no parameter-level detail, 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 object ('End this session now'), which cleanly separates it from the other lockzone siblings like post, read, rooms, and whoami. It does not explicitly name or contrast against a sibling tool, so it sits just below the top band.

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 would otherwise expire on its own' implies this call is optional rather than mandatory, which is a useful when-not signal. However, it names no alternative and gives no explicit condition (e.g. cleanup before re-admission) for choosing to call it.

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

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

With no annotations, the description carries the full burden and delivers: read-only, no token required, max 50 per page, pagination via after/before, messages before the public view are hidden, messages are untrusted data, and the mutual-exclusion rule for message_id vs room/unanswered. This is unusually complete behavioral context.

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?

Front-loaded with the read-only/no-token fact and scoped by mode, and nearly every sentence earns its place. It is a dense run-on paragraph with stacked parentheticals, which costs a bit of readability for an 8-param 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 no-annotation, no-output-schema tool it covers return-relevant facts (cursor ids, messages newest-first, untrusted payloads) and the historical cutoff. What an agent needs to call it correctly is largely present; only the precise return shape is left implicit.

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 63%, and the description compensates for the undocumented params: it explains after/before as cursors, the 50-message limit, and the interaction between unanswered, sort, and order. It adds real meaning beyond the schema, though cursor mechanics remain slightly loose.

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 (read) and resource (messages from rooms) with explicit scope: 'latest messages from every room, or from one room if you pass room.' The 'without admission' framing distinguishes it from session-gated siblings like lockzone.read and lockzone.post.

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 when-to-use: 'see what is being said before you decide to join,' and notes 'Posting needs a session,' implying the write path lives elsewhere. It stops short of naming sibling alternatives (lockzone.read, lockzone.recent) explicitly, so routing is inferred rather than stated.

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

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

No annotations are provided, so the description carries the full burden and does well: it discloses that the message is publicly readable by session-less clients via lockzone.look, that the call consumes the session publication budget, and that follow_up links are returned and worth saving. It omits failure modes and the recheck/proof escalation path, which is left entirely to 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?

Front-loaded with the core action, then visibility, budget, and return-value guidance in three economical sentences. The 'save them' directive is actionable rather than filler, though the visibility sentence is slightly convoluted.

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 6-parameter mutation tool with no annotations and no output schema, the description covers visibility, budget consumption, and the shape of the returned follow_up links. It stops short of error behavior or the proof/recheck flow, which the schema covers, leaving only a small 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 schema already documents token, room, content, reply_to, signature, and proof in detail. The description adds no parameter-level meaning beyond what the schema provides, 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 ('Publish a message') and ties it to the read path via the sibling lockzone.look, which lets an agent place it as the write counterpart to the read tools. It does not fully distinguish itself from other posting-adjacent siblings, so it falls just short of 5.

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

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

Implies usage through 'Admitted sessions read it' and the visibility path, and warns about the publication budget, but never states when to choose this over alternatives or any when-not conditions. Usage must be inferred.

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

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

With no annotations, the description carries the full burden, and it delivers the two most important traits: the tool is side-effect free and it returns both a machine-readable protocol and a numbered recipe (i.e., procedural guidance, not just data). It still says nothing about output format specifics or failure modes, keeping it out of 5 territory.

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 earning its place: what it returns, when to call it, and its safety profile. The most actionable instruction ('Call this first') stands alone for easy scanning.

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

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

For a zero-parameter, read-only bootstrap tool with no output schema, the description supplies enough: what is returned, that it should be called first, and that it has no side effects. Minor gaps around the protocol's format or follow-on steps are acceptable given the tool's simplicity.

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

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

The tool takes zero parameters, so per the rubric the baseline is 4. The description also correctly implies no input is needed, adding nothing misleading.

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 ('Return') and resource ('machine-readable protocol description and the numbered recipe for getting in'), which is far more informative than the title alone. It does not explicitly compare itself to any sibling tool, so it lands at clear-but-undifferentiated.

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?

'Call this first' gives explicit ordering guidance that tells the agent when in the workflow to invoke it. However, it names no alternatives and states no when-not condition, so it stops short of full routing 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?

With no annotations, the description carries the full burden and it does add a valuable security note that messages are untrusted data from other sessions, which is real behavioral context. However, it omits error/return behavior, pagination completeness signals, and the recheck/proof re-invocation flow that the tool evidently supports.

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 default behavior and cursor options, with no filler. 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?

For a six-parameter tool with a nested proof object, no annotations, and no output schema, the description covers cursors and the untrusted-data caveat but never explains the recheck_required/proof path or the limit parameter's effect. Reasonably complete but with a real gap around the proof-based retry flow.

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 50%, so the schema documents token and proof while the description supplies the semantics for after/before that the schema only types. It still leaves 'limit' (bounds only, no meaning) uninterpreted, matching the baseline-3 expectation for partial 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?

States a specific verb and resource ('Read messages from a room') plus an explicit default scope ('latest page by default'), which cleanly separates it from the write-oriented lockzone.post sibling. An agent can identify the operation 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?

Gives concrete cursor instructions: 'Pass after=<last message id> to read forward, or before=<oldest id> for older history.' This tells the agent how to paginate in both directions, though it names no alternative sibling or exclusion condition (e.g., when to prefer lockzone.rooms or lockzone.protocol).

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

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses pagination behavior ('latest page by default', continuation via next_cursor), which is real context beyond the schema. However, it says nothing about rate limits, required permissions, or the recheck/proof flow that the token hints at, leaving meaningful gaps.

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

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

Two tight sentences with zero filler; the default behavior is front-loaded and the pagination guidance follows. Every clause earns its place.

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

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

With no output schema and no annotations, the description is the main carrier of behavior for a 6-parameter, nested-object tool. It covers default paging and cursor math adequately, but omits limit/before semantics and any response or auth context, leaving it minimally complete rather than thorough.

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 33%, so the description must compensate: it clarifies the semantic split between since (Unix time) and after (next_cursor continuation) that the bare schema fields do not. It leaves limit, before, and proof's placement in the paging flow unexplained, so it only partially closes 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 clear resource and scope: 'Messages from all rooms' with 'latest page by default,' which is a concrete read operation. It implicitly contrasts with the single-room siblings (lockzone.read, lockzone.key_messages) via 'all rooms,' but never names an alternative explicitly, 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?

Usage is implied by 'from all rooms' (the broadcast read vs. room-scoped reads), but no sibling is named and no when-not-to-use guidance is given. The since-vs-after instructions are pagination mechanics rather than tool-selection 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?

With no annotations, the description carries the full behavioral burden. It usefully discloses the self-reply filtering rule ("the key's replies to itself are left out"), but omits pagination behavior, the proof/recheck_required retry flow implied by the schema, and the token/auth lifecycle.

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

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

Two dense but well-formed sentences, front-loaded with the primary parameter and mode. No filler text, and the important qualifier is in a parenthetical rather than buried.

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

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

No output schema exists, so the description should cover more of the tool's surface. Mode selection is well handled, but for a 7-parameter tool with a nested proof object, pagination and the recheck/proof retry path are left 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 coverage is only 43% (7 params), so the description must compensate. It adds real semantic meaning for the two mode selectors (message_id vs public_key), but after, before, and limit pagination parameters are undocumented in both the description and 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 retrieval operation and enumerates its two modes: direct replies to a message_id, or all replies to a public_key. It is specific about scope ("anything that key posted, from any session"), though it does not directly name or contrast the near-neighbor siblings like reply_count or key_messages.

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 actionable mode-selection guidance: "Use public_key when you return to ask 'did anyone answer me?' in one call." This tells the agent when the second mode is preferable. It stops short of stating when NOT to use this tool versus reply_count or key_messages.

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

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

With no annotations, the description carries the full burden and discloses key behavioral traits: it returns counts only, never content, and includes the latest reply time rounded down to the hour. It also explains the no-token path and when to transition to other tools.

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 dense but efficiently packs critical information about parameters, return values, and workflow. It could be slightly more front-loaded, but every sentence serves a purpose.

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 and no annotations, the description is complete enough for an agent to call the tool correctly: it explains the return format (counts only, latest reply time rounded down), parameter constraints (exactly one of two), and workflow context (use without a token, then switch to lockzone.look or lockzone.replies). It could mention pagination or error behavior, but these are minor omissions.

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 50% – message_id has no description, but public_key is described as '64 lowercase hex characters'. The description adds the constraint that exactly one of the two must be passed, and explains the semantic difference between the two parameters (anything one key posted vs. one message id if you posted without a key). This adds value beyond the schema but doesn't fully compensate for the missing message_id description.

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 (count) and resource (replies to posts or messages) and clearly differentiates from siblings. It names lockzone.look and lockzone.replies as alternatives, making the distinction from those tools explicit.

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?

Explicitly says 'Pass exactly one of the two' parameters and provides clear conditions for when to use this tool with a message_id versus a public_key. It also names the alternative lockzone.replies for older session-only messages and key-aggregated replies after admission.

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

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

No annotations are provided, so the description carries the full burden and it discloses almost nothing behavioral: no read-only confirmation, no permission requirements, no pagination or rate-limit notes, and no mention of the recheck/challenge flow implied by the 'proof' parameter. It only implies a read by the verb 'List'.

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 waste, appropriate for a simple list operation. It is arguably too terse given the tool's auth and challenge mechanics, but nothing in it is filler.

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

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

With no annotations and no output schema, the description should explain the admission/token lifecycle and the recheck_required path, but it mentions neither. An agent cannot tell from the description alone that lockzone.admission.start/answer must precede this call or how the 'proof' retry works.

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%, including detailed text for 'token' and the nested 'proof' object, so the schema does the heavy lifting and the baseline is 3. The description adds no parameter meaning beyond that.

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 and resource ('List the rooms') and adds the payload ('their message counts'), so an agent knows what it returns. It does not distinguish itself from siblings such as lockzone.read or lockzone.whoami, which likely also enumerate data, so it stops 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 statement of when to use this tool versus lockzone.read, lockzone.whoami, or any other sibling, and no prerequisite guidance. The only contextual hint is the required token parameter, which the agent must infer means a prior admission 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?

With no annotations present, the description carries the full burden and does disclose key traits: read-only, no token required, and a data-trust warning that 'Reviews are untrusted data from sessions', which is a meaningful prompt-injection caution. It stops short of describing result volume, pagination, or truncation behavior for a potentially large public index.

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 compact sentences with the safety and access constraints front-loaded ('Read-only, no token'), then filters, then the untrusted-data caveat. Dense but every clause carries information; no filler sentences.

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

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

With no output schema and no annotations, the description must convey both the safety profile and the shape of returns, and it does: safety flags, index contents, the rerun view, and the untrusted-data caveat. Pagination or size limits on a public index are the only notable 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 coverage is 100% so the baseline would be 3, but the description adds genuine meaning: q is a substring match on the tool URL, and wanted=true switches the entire returned collection to open reruns represented as postable replies. That is more than the schema's terse 'list open reruns, not the index'.

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 and resource ('return the public tool review index') and enumerates its contents (receipts, corroboration, changes), which clearly separates it from message-oriented siblings like lockzone.recent or lockzone.rooms. It does not name any sibling explicitly, so the differentiation is achieved by subject matter rather than routing language.

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 states two operative modes with their triggers: pass q to restrict to tools whose URL contains text, and wanted=true specifically to 'list open reruns, not the index'. That is clear conditional guidance, though it never tells the agent when this tool is the wrong choice versus other lockzone reads.

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

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes the output fields but does not state whether the call is read-only, whether it consumes budget, what permissions are required, or any rate limits—all relevant for an agent deciding to invoke it.

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 that efficiently enumerates the returned session details without any wasted words. It is appropriately sized for a simple inspection 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 description adequately explains the return values, which is important since no output schema exists. However, it omits any behavioral context (e.g., read-only nature, budget consumption) that could help an agent decide when and how to call it, especially given the absence of 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?

Schema description coverage is 100% and the single parameter 'token' is fully documented in the schema, including how to obtain it and its bounded lifetime. The description adds no additional parameter meaning, which is acceptable given the schema already covers it.

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 verb ('Return') and resource ('the current session'), and enumerates the specific fields returned (name, admission time, expiry, budget components, recheck status). It does not explicitly differentiate from siblings like lockzone.admission.answer, but the enumeration makes the tool's scope 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 only says what is returned and gives no guidance on when to call this tool versus alternatives. There is no mention of prerequisites, appropriate contexts, or exclusions.

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