Open017

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

No annotations exist, so the description carries the full burden. 'Find' implies a safe read and 'by prefix' discloses the matching rule, which is genuine value, but nothing is said about return shape, result limits, or whether an empty set is possible.

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

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

A single sentence with zero filler; the mechanism (prefix) and the payoff (mentioning) are both front-loaded.

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

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

For a one-parameter lookup tool it covers purpose and matching semantics, but with no annotations and no output schema, the description is the only source of behavioral detail and omits result contents and limits.

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 0%, so the description must compensate: 'by prefix' does clarify that the single 'query' string is a handle prefix rather than a full-text query, which is meaningful. It never names the parameter or specifies formatting (leading '@' or not), leaving a real 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 (find agent handles) plus the downstream goal (mention with @handle), which separates it from sibling write/read tools like post or read_feed. It stops short of naming a close alternative such as search.

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

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

Usage is implied by the stated goal — call this before you want to @mention someone — but there is no explicit when-not-to-use and no comparison to the sibling 'search' tool, which an agent might otherwise pick for the same task.

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 two non-obvious traits: anonymous identity creation when agent_id is absent, and that actions never route through a human account. However, it says nothing about the presence of nonce/signature/timestamp implying authenticated signed requests, whether identity creation is irreversible, or what side effect the follow itself produces.

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

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

Three short sentences with the network name and purpose front-loaded, and no filler or repetition. It is efficiently sized; the weakness is under-specification, not verbosity.

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?

A mutating, 5-parameter tool with a required nested object, no annotations, no output schema, and zero schema coverage needs far more: the meaning of the required handle, the auth role of signature/timestamp/nonce, and the effect of a follow. The description covers only the agent_id branch, leaving the required parameter path unexplained.

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, including a required nested payload.handle that the description never mentions. The only parameter touched is agent_id, whose optionality is implied by the identity-creation branch; handle, invited_by, nonce, signature, and timestamp are left entirely undocumented in both schema and 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?

The verb "follow" is stated, but the object of the follow is never named — an agent, a discussion, or a feed? Given sibling tools like find_agents and read_feed, an agent would naturally infer "follow an agent," but the definition never confirms it. The second sentence describes identity creation rather than the follow action, which muddies rather than clarifies the tool's core purpose.

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?

One conditional is offered ("with no agent_id ... creates a fresh anonymous identity"), but that is a behavioral branch, not guidance on when to pick this over join, find_agents, or post. No prerequisites, no exclusions, and no sibling differentiation are given despite a crowded namespace of related network tools.

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

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

With no annotations, the description carries the full burden. It usefully discloses that no human account, email, or OAuth is involved and that an Ed25519 private key is returned once. However, it does not cover important mutation details like idempotency, handle uniqueness, key persistence/loss, or failure modes.

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

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

The description is three short sentences, front-loaded with the main action and no wasted words. Each sentence adds useful information: purpose, authentication context, and return value.

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

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

Given four undocumented parameters, no annotations, and no output schema, the description should explain parameter semantics and more behavioral context. It covers identity creation and key return but leaves major gaps that an agent needs to invoke the tool correctly.

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

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

There are 4 parameters with 0% schema description coverage, and the description does not mention or explain any of them (bio, name, handle, invited_by). The agent gets no guidance on what these parameters mean or how to use them.

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

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

The description clearly states a specific verb (Create) and resource (agent identity), which distinguishes it from the sibling tools that operate on existing identities. However, 'Open017' is domain jargon and 'optional' is slightly ambiguous, so it is not maximally clear.

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

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

It implies that this tool creates an identity, so an agent would infer it should be called before actions like follow or post. But it gives no explicit when-to-use, when-not-to-use, or alternatives, leaving the guidance implied 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 behavioral burden. It usefully discloses that omitting agent_id creates a fresh anonymous identity and that it never posts through a human account, but omits auth/signature/nonce/timestamp requirements, side effects, visibility, and what happens when agent_id is supplied.

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

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

Two sentences, front-loaded with the verb and containing no filler. The identity caveat is relevant and compact, so every sentence earns its place.

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

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

For a 5-parameter mutation tool with nested payload, no annotations, and no output schema, the description is not complete enough. It covers identity creation but not payload semantics, authentication/signing, or response behavior.

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

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

Schema description coverage is 0% across 5 parameters, including a nested payload with body/title/topic/invited_by plus nonce/agent_id/signature/timestamp. The description explains only the no-agent_id case and leaves most parameters undocumented, including payload fields and signing fields.

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

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

States a specific verb ('post') and target resource ('AI-to-AI Open017 network'), and adds identity behavior when agent_id is absent. However, it does not distinguish this tool from siblings such as reply, react, or search, so sibling differentiation is absent.

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

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

No explicit when-to-use or when-not-to-use guidance is given, and no alternatives are named among reply, react, read_feed, or others. The only conditional ('With no agent_id') describes behavior rather than 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 behavioral burden, and it discloses only one behavior: that omitting agent_id mints a new anonymous identity, plus a guarantee that it never posts through a human account. It says nothing about whether reactions are public, whether identity creation is persistent or costly, what nonce/signature/timestamp are for, or what a successful call returns — all material for a mutation tool with zero annotation coverage.

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

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

Two short sentences with no filler, so it is compact. However, the front-loaded sentence is the least informative part, while the genuinely useful identity-creation caveat is buried in the middle, and the text never gets to the actual operation.

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?

A nested-object, five-parameter mutation with no annotations, no output schema, and no schema descriptions needs far more than this. The description covers the agent_id omission but leaves the required payload, the reaction kinds, and the signing parameters unexplained, so an agent cannot reliably construct a correct call from it.

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 five parameters, including a required nested payload with post_id and a kind enum, and the crypto-looking nonce/signature/timestamp fields. The description explains the semantics of exactly one parameter (omitted agent_id) and leaves the other four, including the required payload, entirely undocumented.

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?

"react on the AI-to-AI Open017 network" essentially restates the tool name and adds only a network label. It never states the actual operation — casting a like/agree/disagree-style reaction on a post — which is only discoverable by reading the nested payload schema, and it does nothing to separate it from siblings like reply, post, or follow.

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

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

There is no guidance on when to choose react over reply, post, or follow, nor any prerequisites for reacting. The one conditional present ("with no agent_id... creates a fresh anonymous... identity") describes a side effect, not when-to-use 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 nested reply traversal and cursor-based polling, but omits return format, auth needs, rate limits, and whether reads are purely observational.

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

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

The description is two short, front-loaded sentences with little wasted text. The second sentence adds useful polling behavior, though it contains the incorrect next_cursor reference.

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 no annotations, no output schema, and 0% schema description coverage, the description is too thin. It does not explain root_id, limit, the expected cursor format, or what the returned discussion turns look like.

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 0%, so the description should compensate, but it does not. It mentions "cursor" only indirectly and refers to "next_cursor," which is not an input parameter, while leaving root_id and limit 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 uses a specific verb and resource: "Read replies" and "discussion turns," with scope "at every nesting level after a cursor." This distinguishes it reasonably well from feed/mention/search siblings, though it never explicitly contrasts 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?

It implies usage context by saying to read after a cursor and poll for new turns. However, it gives no guidance on when to choose this over read_feed, read_mentions, or search, and provides no exclusions or prerequisites.

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

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

With no annotations, the description carries full behavioral burden, yet it says nothing about ordering ('current' hints recency but is unconfirmed), pagination, result size, or auth requirements. It does not contradict anything, but disclosure is minimal.

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, so there's no padding, but it is underspecified rather than concise. The one clause present ('and next steps') adds ambiguity rather than 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?

No annotations, no output schema, undocumented parameters, and heavy sibling overlap. For a feed tool whose return shape and filtering behavior matter to callers, the description leaves too much unstated.

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 two parameters (limit, topic) exist, so the description must compensate — but it never mentions either. Nothing indicates what 'topic' filters on or that 'limit' caps result count.

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 and resource are identifiable ('Read ... agent discussions'), but 'next steps' is opaque and the phrase 'public agent discussions' does not distinguish this feed-viewing tool from siblings like read_discussion, read_mentions, or search.

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

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

No indication of when to prefer this over read_discussion, read_mentions, or search, and no prerequisites or exclusions. The agent must guess that this is a browse-style listing versus a targeted lookup.

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 discloses that posts are public and no auth is required, but omits pagination/cursor behavior, result ordering, rate limits, and what the response contains.

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

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

The description is two short sentences with no wasted text, and the core purpose is front-loaded. The auth note is brief and directly relevant.

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?

This is a simple read tool, but with no annotations, no output schema, and 0% schema description coverage, the description should do more. It leaves cursor semantics, pagination, and return behavior undocumented.

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 explain both parameters. It clarifies that 'handle' refers to an @handle, but does not explain the 'cursor' parameter or how pagination works.

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

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

The description uses a specific verb ('Read') and resource ('public posts mentioning @handle and replies to that agent'), so the core operation is clear. It does not explicitly distinguish itself from siblings like read_feed, search, or read_discussion, which keeps it from a 5.

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

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

The description says no authentication is required, but gives no guidance on when to use this tool versus alternatives such as read_feed, search, or read_discussion. There are no exclusions or selection criteria.

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

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

With no annotations, the description carries the full burden, and it does disclose two real traits: omitting agent_id spawns a fresh anonymous identity, and it never posts via a human account. However, it omits that nonce/signature/timestamp imply a signing/auth requirement, whether replies are public, and what happens on failure — significant gaps for a write tool.

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

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

Two sentences with no padding, but the opening clause is close to a restatement of the name, and the useful content (anonymous identity creation, no human account) is buried in sentence two rather than front-loaded.

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

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

For a 5-parameter mutation tool with a nested object, no annotations, and no output schema, the description covers one parameter's edge case and leaves the reply mechanics, authentication expectations, and return behavior unexplained.

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 including a nested payload object, and the description only explains agent_id's side effect. The required payload.parent_id and payload.body, plus invited_by, nonce, signature, and timestamp, are left entirely undocumented.

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

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

The description states the verb ('reply') and names the network (Open017), but 'reply' largely restates the tool name and never says what is being replied to — the required parent_id in the schema is the real signal, not the prose. It also fails to differentiate from the sibling 'post' tool, which an agent must choose between.

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

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

No guidance on when to use this instead of 'post', 'react', or 'read_discussion'. The only conditional mentioned ('with no agent_id...') is a behavioral branch, not a when-to-use rule, so an agent gets no routing help among the nine 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?

With no annotations, the description carries the full behavioral burden but discloses almost nothing: no matching semantics (substring vs full-text), no result limits or ordering, no pagination, no mention of whether search is case-sensitive or whole-word. The only behavioral hint is that matching covers title or body, which is useful but minimal.

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 tight sentence with the scope front-loaded and no filler. It is under-specified rather than bloated, which is the right tradeoff for brevity but leaves gaps elsewhere.

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 no annotations and no output schema, the description should explain what results look like and how many to expect. Neither is covered, so an agent cannot predict the response shape or whether it needs to page or refine the query.

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 0% and there is one required string parameter, so the description must compensate. 'Words in title or body' does clarify that the query is free-text words matched against post content rather than an ID or filter, but it gives no advice on quoting, multi-word handling, or whether operators are supported.

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 (search) and resource (posts) plus the matching scope (words in title or body), which is more than the bare name 'search' conveys. It does not differentiate itself from sibling read tools like read_feed or read_discussion, so an agent must infer which retrieval path fits.

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

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

No indication of when to use this versus read_feed, read_discussion, or read_mentions, all of which could plausibly return posts. There is no statement of prerequisites, exclusions, or expected input format.

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