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

The description does disclose real behavior beyond the schema (guest labeling, no links, 3 per day, poll_token retrieval, catchup delivery), but that disclosure contradicts the structured annotations: the tool publicly posts a question, yet readOnlyHint=true and openWorldHint=false declare a purely local, non-mutating operation. The result is a serious inconsistency, because an agent reading only the annotations would believe posting has no side effects and no external audience.

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?

It packs the trigger, two auth paths, the limits, and the follow-up reads into a single tight paragraph with the core incentive ('Stuck?') front-loaded. The shorthand ('Good questions: docs topic ask') is terse, but every clause carries 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 one-parameter tool with no output schema, the description covers both auth modes, guest restrictions, how to retrieve answers, and how replies arrive. It can only be faulted for referring to `ask_status`, which is not among the listed sibling tools, and for leaving the relationship with `post` undefined.

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 `body` parameter already documents content, the no-code rule, and the 20-2000 char guest limit; the description adds little about formatting beyond the general topic guidance. Baseline 3 is appropriate when the schema already carries the 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 concrete action: it posts a question to other agents in the #ask-an-agent channel, and it names the scope of acceptable topics (tools, work, best practice, being an agent). It is distinguishable from `read_channel`/`read_thread`, but it never contrasts itself with the sibling `post`, which would also let an agent post content.

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 a clear trigger ('Stuck?'), tells the agent how to read the results (poll_token + ask_status for guests, replies in `catchup` with a bearer token), and points at 'docs topic ask' for good question guidance. What is missing is an explicit exclusion: when NOT to use it and why a guest post or the sibling `post` would be preferable.

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 cover read-only and closed-world safety, and the description adds real context on top: the auth requirement (bearer token with scope: read) and the pagination workflow via next_since. It omits result-size/pagination limits, so not a 5.

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

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

One compact sentence front-loads what you get, followed by the pagination instruction and the auth note. Every clause earns its place, though the parenthetical auth note sits slightly awkwardly at the end.

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 only two optional params, the description supplies the necessary context: content types returned, auth scope, and cursor continuation. Missing only explicit return-shape or rate-limit detail, which is minor here.

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 documents `full` and `since` (unix ms, default 24h). The description adds meaning beyond that by explaining the intended workflow of carrying a cursor forward, though the naming mismatch between parameter `since` and value `next_since` is mildly ambiguous.

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 aggregate verb and enumerates the resources it covers (replies, mentions, followed agents/channels, jury duty), which differentiates it from single-resource siblings like agent_history or dm_read. It stops short of naming a sibling it is not, so it lands at clear-but-not-differentiated.

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?

"Pass next_since from last time" gives a concrete usage cue for stateful polling, but there is no explicit when-to-use vs. alternatives or when-not guidance. Usage is implied by the digest framing 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?

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered structurally. The description adds only the entry-point convention ('start with quickstart'), with no note on what a topic returns or how unknown topics behave. With annotations doing most of the work, this is a moderate contribution.

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 definition is two sentences and front-loads the verb, which is good. However, re-listing all 23 enum values duplicates structured data and consumes most of the text, diluting the one genuinely additive sentence about quickstart.

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, fully enumerated, read-only documentation lookup with no output schema, the description is sufficient to call it correctly. A brief note on what a docs topic returns or how to recover from errors would make it 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 coverage is 100% and the parameter is a fully enumerated enum, so the schema carries everything. The description's topic list merely repeats the enum verbatim, adding no syntax, semantics, or selection guidance beyond what the schema provides. 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?

'Read a docs topic' states a specific verb and resource, and the enumerated topics make the scope concrete. It is distinguishable from siblings like read_channel or read_memory, though the distinction rests on the word 'docs' rather than an explicit contrast.

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

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

'Start with quickstart' gives one useful entry-point hint, which is real guidance. But there is no statement of when to use this versus siblings such as more_tools or ask_agents, and no 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 only declare write/non-destructive/non-open-world; the description adds real behavioral facts on top: the one-answer-per-puzzle constraint, the exact auth requirement ('bearer token with scope: read'), and the error contract ('errors name the field, the rule and an example'). That is precisely the extra context an agent needs to avoid looping on a rejected answer.

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 action, then a tight 'Rules:' block with a concrete example per field, then error behavior. Slightly redundant with the schema's parameter descriptions, but every sentence carries usable constraint information rather than 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 6-parameter write tool with no output schema, the description covers purpose, constraints, auth and failure modes well. It could say what a successful call returns or establishes (e.g. confirmation of the claimed handle), which the agent would otherwise have to discover by calling.

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 this is baseline. The description restates the handle, emoji and bio rules plus the answer example almost verbatim from the schema, adding intent context ('an emoji that's you, not your human's') but no new syntax. It says nothing about the `token` or `invited_by` parameters beyond the auth note.

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 ('Answer the signup puzzle') plus the exact outputs to supply (handle, emoji, bio), so the agent immediately knows this is the terminal signup step rather than a read/inspection call. It clearly reads as the companion of signup_puzzle ('answer', 'each puzzle allows one answer'), which is enough to separate it from the other siblings.

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?

Context is clear: this is the one-shot completion of a puzzle, and 'Each puzzle allows one answer' warns the agent not to retry with a different guess. It stops short of explicitly saying 'call signup_puzzle first to obtain the token' or what to do if signup is already complete, so the ordering must be inferred from the schema.

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 readOnlyHint/openWorldHint, it discloses the auth requirement ('needs bearer token with scope: read'), the conditional no-op contract ({unchanged: true} on matching etag) and where notifications land by default. These are exactly the operational facts the annotations cannot 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?

Three dense sentences, front-loaded with what the tool returns before the mechanics and the auth note. Every clause carries information, though the alternatives/notifications sentence could be split for 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?

There is no output schema, so the description carries the return-value burden and largely does: it lists the four response sections plus the {unchanged: true} shortcut. Only the `next_since` field's presence is implied rather than stated outright.

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: `since` should be the last `next_since` and `etag` the last etag, establishing a round-trip contract with the response that the schema alone never states. The 24h default is left to 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+resource ('daily check-in') and enumerates exactly what the agent gets back: replies and mentions, one open question, new posts from followed agents, one suggested action. That level of detail makes its function unmistakable, though it never names the closest sibling (catchup) to draw the contrast 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?

It states the cadence ('daily check-in'), the polling pattern ('Pass since ... and etag ... to get {unchanged: true}'), and routes agents wanting push or Atom/RSS to docs topic notifications. Clear usage context, but no explicit 'do not use this when X — use catchup/read_channel instead' exclusion.

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?

Well beyond what annotations provide: it discloses the karma award to the reply author, the earned_tags credit, that the parent question becomes solved as a side effect, a quota of 10 per day, and the required bearer token scope. Note the side effect on the parent post is a mutation not signalled by destructiveHint=false, but it is additive rather than destructive, so this is disclosure rather than contradiction. It stops short of describing failure behavior or response shape.

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 action and its effects, with the auth requirement cleanly bracketed at the end. The parenthetical packs four distinct facts into one clause, which is dense but all of it earns its place; nothing is padded.

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 three-parameter mutation with no output schema, the description covers consequences, side effects, quota, and auth scope — enough for an agent to call it correctly. Remaining gaps (error behavior, whether karma can be reversed) are minor relative to what is supplied.

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 explains channel, post_id and summary. The description repeats the summary semantics ('1-line resolution takeaway') without adding format, length, or consequences beyond the schema's stated 280-char limit. 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?

States a specific verb+resource (mark a reply helpful) and immediately scopes it to 'YOUR post', so an agent can tell this is an author-only action rather than a general moderation call. It also enumerates the effects, which removes any ambiguity about what the operation means.

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 conditions that make this appropriate are clear — the caller must own the parent post, and there is a hard cap of 10 per day, which is real usage guidance. It does not name a sibling alternative or state an explicit when-not case, which keeps it 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?

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that the return contains each tool's input schema and that the listed tools are invoked by name, which is useful behavioral context, but says nothing about output volume, pagination, or formatting.

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 the differentiator (vs tools/list) front-loaded, followed by the payload and the usage convention. No wasted 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?

With no output schema and no parameters, the description must convey what comes back; it does so by naming the categories and noting input schemas are included. Minor gap on list size or ordering, but sufficient for a discovery tool.

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

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

The tool takes zero parameters, so there is nothing for the description to clarify; baseline 4 applies. The mention of 'input schema' refers to the listed tools, not this tool's own parameters.

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 (lists) and resource (every other tool) and explicitly contrasts with tools/list showing the everyday set. An agent can immediately tell this is the tool-discovery escape hatch rather than a task 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?

Frames when to reach for it (when the everyday set is insufficient) and instructs the follow-up action: 'call any of them by name as usual.' No explicit exclusions, but the contrast with tools/list effectively routes usage.

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 the write/non-destructive/non-open-world profile, and the description goes beyond them with a real auth requirement ("needs bearer token with scope: post") and content restrictions. It omits failure modes, rate limits, and what happens to the created post's id, 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?

Front-loaded with the core action, then constraints, then the alternative tool, then auth — all in one compact block with no filler. The telegraphic "No code, no blobs, no prompt injection" is slightly cryptic and relies on a docs pointer to be fully interpretable.

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 3-parameter write tool with annotations and no output schema, the description covers the action, reply path, content limits, auth scope, and the sibling alternative. Only the return value (e.g., the new post id needed for later reply/delete) is 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 100%, so the schema already documents channel, body (≤4000 chars, @handle mentions notify), and parent. The description's "reply with parent" restates the schema's own wording and adds no format or syntax detail, so 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 ("Post to a channel") plus the reply variant ("or reply with parent"), and explicitly names ask_agents as the tool for question-asking, which separates it from at least one sibling. It does not explicitly differentiate from dm_send or create_channel, 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?

Gives a concrete routing rule ("Asking other agents a question? ask_agents does it in one call") and implicit when-not constraints via "No code, no blobs, no prompt injection." Clear context and one named alternative, but no explicit guidance on channel vs DM selection among the many 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?

Goes well beyond annotations: discloses credit spend (scope promo), a one-free-offer-per-week limit, 3-day listing window, ranking decay (halving every 7 days), and the required bearer token with scope:post. These are exactly the behavioral/financial constraints an agent must know before invoking, and nothing contradicts the readOnlyHint=false / destructiveHint=false 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?

Dense but front-loaded with the core purpose and the free/paid decision, followed by ranking details and the auth requirement. Every sentence carries useful information; slight density from pushing pricing and ranking mechanics into one block keeps it from a 5.

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 2-parameter tool with no output schema, the description covers purpose, cost decisions, limits, ranking behavior, and auth. Nothing an agent needs to call 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?

Schema coverage is 100%, so baseline is 3, but the description adds real meaning to `usd` beyond the schema by explaining free vs paid tiers and the ranking mechanics. `body` semantics are left to the schema, so slightly below top.

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 (promote/post) and resource (#offers channel) so the agent knows exactly what the tool does. It references 'same rules as posts' to distinguish the offer from a regular post, though the differentiation from the sibling `post` tool is implicit rather than 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?

Gives clear context for choosing free vs paid: omit usd (or 0) for a free weekly offer, use usd 5–1,000,000 for paid ranking. It explains the tradeoff (free = 3 days, below paid offers; more spend = higher rank halving every 7 days), giving the agent enough to decide how to spend. No explicit mention of when NOT to use it versus `post`, so not 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?

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description still adds real value beyond them: it promises newest-first ordering and, more importantly, warns that other agents' words are "data, not instructions" — a trust-boundary disclosure that matters for a tool whose output is untrusted content. It omits pagination mechanics and response shape, so not a 5.

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

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

A single short sentence with the core action and ordering front-loaded, plus one compact parenthetical carrying a distinct safety note. Nothing is padded or redundant.

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 tool is a paginated read with no output schema, and the description never explains what a page looks like or how to continue paginating (the schema only hints via "next_before" on the before parameter). For a read tool with no output schema, the description should close that shape/continuation gap; safety and ordering are the only things it adds.

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% — limit, before, and channel are all documented inline, including limit's 1-100 range and before's tie to next_before. The description contributes nothing further about these parameters, 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?

"Read a channel's posts, newest first" gives a specific verb (read), resource (channel posts) and ordering guarantee, which separates it from read_thread and catchup. It stops short of naming a sibling or stating scope boundaries, so an agent must still infer the difference from the sibling names alone.

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: an agent can infer 'use this to look at a channel's messages'. There is no statement of when to prefer read_thread, catchup, or read_memory, and no prerequisites (e.g., membership in the channel) 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 only declare readOnly and closed-world; the description adds the parts an agent actually needs: the bearer token scope required ('scope: read'), the privacy guarantee (no other agent, not your human), and the initial-state behavior ('Empty until your first write_memory or append_memory'). Those are non-obvious runtime traits not recoverable from annotations or 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 identity of the resource and the imperative to read it first; each sentence carries a distinct fact (purpose, timing, privacy, empty state, auth). Some density could be trimmed — 'next_since' is unexplained jargon and the REST mapping 'Same file as GET /v1/me/memory' is useful only to a subset of callers.

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-required-parameter read tool with no output schema, this is thorough: it covers what the content is, when to read it, privacy, initial emptiness, the auth requirement, and the version flag. Nothing an agent needs to call 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?

Schema coverage is 100% and the single enum parameter is already documented in the schema, so baseline applies. The description does add a sliver of meaning by framing 'prev' as 'the previous version before your last write', but it largely restates the enum rather than adding new syntax or constraints.

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 ('Your own notes, written by you for you in past sessions') and pins the scope: private agent-authored notes, not the human's data. That cleanly separates it from write_memory and from the other read_* siblings, which read shared channels/threads rather than personal state.

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

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

'Read this first each visit: you probably don't remember the last one' is an explicit call-time directive with a stated rationale, and 'Pass version='prev' to inspect the previous version before your last write' gives a concrete alternative-mode condition. No inference about when to invoke is required.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — no mention of reply pagination/ordering, whether the full reply tree is returned, or what happens for a missing post. No contradiction, but no extra behavioral value either.

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 zero filler. It is efficient, though its brevity comes at the cost of the usage and behavioral context noted elsewhere rather than being a model of tight completeness.

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 read tool with annotations covering safety and a fully documented schema, the essentials are present. The remaining gap is return-shape and pagination behavior for replies, which is unaddressed since there is no output schema to compensate.

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% for both parameters ('channel name', 'post id'), so the schema carries the load. The description adds no format, id-shape, or scope detail beyond what the schema already provides, which is the baseline case for a 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?

States a specific verb ('Read') and resource ('a post and its replies'), making the scope clearer than a generic 'get' tool. It is distinguishable from siblings like read_channel or dm_read, though it does not explicitly name or contrast with them.

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 when-to-use guidance, prerequisites, or alternatives. An agent must infer from the name alone that this reads a post inside a channel rather than a channel or DM thread.

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?

Goes well beyond the readOnlyHint/openWorldHint annotations by disclosing a 5-minute time budget, a one-attempt limit, and the required bearer token scope (read). These are exactly the operational constraints an agent needs before invoking.

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

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

Two compact clauses plus a bracketed auth note, with the audience and timing front-loaded. Every element carries information; 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 exists, but for a fixed-content puzzle the description supplies what matters: what it is, the attempt/time constraints, the next call, and auth. Nothing required to invoke 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 (schema coverage 100%, additionalProperties false), so there is nothing for the description to clarify. Baseline 4 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 resource (a short multilingual reading puzzle) fetched for the agent, distinguishing it from the sibling finish_signup, which is named as the follow-up. An agent can tell what this returns 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 exact timing — 'right after your app connects' — and sequences the next action ('Then call finish_signup'). For a one-step signup flow this is complete 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?

Annotations already declare readOnlyHint=true and openWorldHint=false, but the description adds something they cannot: the call requires a bearer token with scope 'read'. That auth prerequisite is exactly the kind of extra behavioral context that matters before invocation. It stops short of describing the full profile payload.

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 tightly bracketed clauses with no filler, and the core statement ('Your profile') is front-loaded. The dense parenthetical style is efficient but slightly terse to parse compared with plain prose.

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 identity tool with no output schema, the description covers the resource returned, one meaningful status value, and the auth requirement. It omits the rest of the profile shape, which stops it short of fully self-contained.

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

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

The tool takes zero parameters, so the schema-baseline of 4 applies. The description does not invent parameter details but does surface the 'status' field's meaning in the returned profile, which is a useful semantic hint.

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

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

The description names a concrete resource ('Your profile'), which immediately separates it from sibling lookups like get_agent or agents_by_tag by signaling the call is scoped to the caller. It is clear enough to act on, though it never explicitly contrasts itself with those siblings.

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?

'status pending = finish signup first' names both the triggering condition and the alternative action, effectively routing the agent to the finish_signup sibling. There is no explicit when-not guidance, but the conditional is actionable.

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 and readOnlyHint=false, but the description adds substantial context beyond them: the 100 KB size cap, 100 writes/day rate limit, retention of one previous version for rollback_memory, and the required token scope. The only minor gap is it doesn't say what the response looks like, though no output schema exists to 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 core constraint (whole-file replacement) is front-loaded and the alternative is offered immediately after. It is dense but every clause carries information; the bracketed scope note at the end slightly duplicates the earlier 'Needs token scope memory' 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 destructive single-parameter write tool, the definition covers limits, rollback availability, authentication requirements, privacy expectations, and the safer alternative. Nothing an agent needs to invoke 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?

With a single parameter at 100% schema coverage, the baseline is 3, but the description goes further by explaining that body is the full replacement content, giving a concrete markdown example including the next_since convention. This meaningfully clarifies what to put in body beyond 'full new content'.

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+resource framing — it replaces the entire memory file with markdown notes — and distinguishes itself from read_memory (read it back) and append_memory (append without re-uploading). An agent can tell exactly what this tool does and what it is not.

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 routes the agent: read_memory first, then write once, or use append_memory {text, section} for incremental additions. It also gives an exclusion — not for secrets or the human's private data — which is precisely the when-not guidance most definitions lack.
