The description is verbose (over 300 words) but well-structured with sections (segments, knobs, response). It front-loads the core purpose but includes detailed model parameters and α values that could be condensed. Conciseness could be improved.

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?

Despite having no output schema, the description fully specifies the response structure (by_segment, fed_candidates, _diagnostics) and explains each opportunity field. It also mentions caching. For a complex tool with 9 parameters, this provides complete context for autonomous invocation.

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

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

Schema coverage is 100% with good descriptions. The tool description adds further context for knobs (e.g., min_liquidity, max_spread_pp, min_partition_leg_kelly) explaining how they filter opportunities. This extra value beyond schema justifies a score of 4.

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

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

The description clearly states the tool's purpose: 'Scan top Polymarket markets and return opportunities where Pipeworx data disagrees with market price.' It is specific to finding betting edges and distinguishes from siblings like polymarket_arbitrage and polymarket_kalshi_spread.

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

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

The description implies usage context ('Built for "what should I bet on today"') and mentions 'agents discover opportunities without paging hundreds of markets.' However, it does not explicitly state when not to use this tool or compare against alternative tools like polymarket_arbitrage.

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

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

The description extensively explains behavior beyond annotations: snapshots are written on cache-miss, gaps indicate no scans, edge_pp_net includes default slippage, decay uses daily closes, and trend/decay computation details. No contradictions with annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint=false).

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 well-structured with a clear opening purpose, then args, response structure, and limits. It is slightly lengthy but each sentence adds value, with no redundancy. A more concise version could exist, but this is well-organized for its detail.

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

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

Given the complexity (multiple array fields, trend/decay computation, expired opportunities) and no output schema, the description is fully complete. It explains all response fields, edge cases like expired items and snapshot gaps, and limitations like TTL bounds. No gaps remain.

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?

Input schema covers both parameters with descriptions (100% coverage). The description additionally provides default values, clamping for 'days', and clarification that 'window' is a snapshot family (24hr/1wk/1mo). This adds meaningful guidance beyond the schema.

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

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

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

The description gives clear context on when to use the tool (e.g., comparing fresh vs. old wide edges) and provides LIMITS on history depth. However, it does not explicitly state when not to use it or mention alternatives among sibling tools, which would have earned 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 indicate readOnlyHint=true and destructiveHint=false, which the description supports by detailing read-only operations (walking the order book ladder). It adds behavioral context: returns specific fields (top_of_book, vwap_fill_price, slippage_pp, verdict, etc.), explains basket mode details (thin_legs, forced_directional_risk), and warns about partial fills converting arb into unhedged positions. No contradiction with annotations.

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

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

The description is long (~200 words) but front-loaded with the core purpose, then breaks into single-market and basket modes. Every sentence provides necessary context for the complex dual-mode functionality. Minor redundancy could be trimmed, but overall structure is efficient for the complexity.

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

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

No output schema, so the description fully covers return values for both modes (top_of_book, vwap_fill_price, shares_filled, verdict, etc. for single; theoretical_sum, realizable_sum, capture_ratio, profit_usd, per-leg fill detail, thin_legs, etc. for basket). It integrates with sibling tools by warning about partial fills and directional risk, making it complete for an agent to understand when and why to call this 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?

Input schema has 100% parameter description coverage, providing baseline 3. The description adds value by clarifying the default side for basket mode (auto based on partition sum) and the interpretation of size_usd as settlement notional in basket mode, which goes beyond the schema's descriptions.

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

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

The description clearly states it performs a realizable-vs-theoretical edge check against live CLOB order-book depth, distinguishing between single-market and basket modes. It specifies the resource (Polymarket markets/events) and the action (check fill risk), which differentiates it from sibling tools like polymarket_arbitrage and polymarket_edges.

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 explicitly states 'USE THIS before acting on any polymarket_arbitrage SELL/BUY-EVERY-LEG signal or any polymarket_edges trade above ~$500'.

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?

Adds significant meaning beyond schema: explains type-specific parameter structures (e.g., sec_8k items codes, polymarket_edge topics, fred_series series_id) and delivery options with constraints (email, SMS with verification, webhook with signing).

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?

Description clearly states it creates a proactive monitoring subscription to a live-data event stream and returns the subscription id. Distinguishes from sibling tools like list_subscriptions and unsubscribe.

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

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

Provides context on when to use (requires Pipeworx OAuth account, anonymous/BYO cannot persist) and type-specific constraints. Does not explicitly state when not to use or directly name alternatives, but the prerequisites and limitations are clear.

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

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

Annotations already declare safe read-only, non-destructive behavior. The description adds that the tool returns category-bucketed example questions with exact tool+argument shapes, drawn from a live catalog. This provides transparency about the output format and behavior beyond what annotations offer, with no contradictions.

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 well-organized with front-loaded key phrases, examples, and use cases. While slightly long, every sentence serves a purpose: explaining the tool's role, listing categories, and providing usage guidance. It is structured effectively for an agent.

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?

Despite no output schema, the description fully explains the return type (category-bucketed example questions) and covers all aspects: purpose, parameters, usage context, and output. For a simple tool with one optional parameter, it is comprehensive and leaves no gaps.

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

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

Schema coverage is 100% with a clear description. The description adds meaningful examples ('finance', 'pharma', 'betting') and clarifies the effect of omitting the parameter vs. providing a topic. This significantly enhances understanding beyond the schema.

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

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

The description clearly states the tool returns category-bucketed example questions about Pipeworx, serving as an onboarding entry point. It distinguishes from siblings by specifying it's for when the agent doesn't know what Pipeworx can do. The verb 'suggest questions' and resource 'Pipeworx' are specific and actionable.

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 advises 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools'. It also explains when to pass the 'topic' argument vs. calling with no arguments. While it doesn't explicitly state when not to use, the guidance is clear and sufficient.

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, openWorldHint, idempotentHint. Description adds that it returns dimensions with codes and value lists, and requires path ending in '.px', which provides useful behavioral context beyond 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?

Two sentences: first establishes purpose, second gives usage and example. No unnecessary words, highly efficient.

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

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

Despite lack of output schema, description fully explains return type and usage context. Complete for its simple purpose.

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% for one parameter, but the description adds example and format detail (path must end in .px) that enhances understanding, exceeding baseline 3.

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

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

The description clearly states the tool fetches dimension definitions and valid coded values for a MakStat PxWeb table, with a specific verb (fetch) and resource. It distinguishes from siblings like query_table.

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 tells when to use this tool: to build the selection body for query_table, providing clear usage context and linking to a sibling tool.

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

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

The description discloses important behavioral details beyond annotations: the row is deactivated (not deleted) and historical events remain available via recent_alerts. Annotations already indicate destructiveHint=false, but the description adds specific context on what happens.

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 efficiently convey the purpose, constraint, and behavioral effect. Every sentence is essential and 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 simple one-parameter tool with no output schema, the description adequately covers the action, ownership constraint, and deactivation behavior, making it complete for an agent to use 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?

The input schema has 100% coverage with a clear description of the 'id' parameter. The description adds only 'by id', which is redundant, and does not provide additional semantic meaning beyond the schema.

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

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

The description uses the specific verb 'Cancel' and resource 'a subscription by id', clearly distinguishing it from sibling tools like 'subscribe' and 'list_subscriptions'.

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

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

The description provides clear context that ownership is enforced (you can only cancel your own subscriptions), but does not explicitly state when not to use or suggest alternatives.

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

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds valuable behavioral context: returns verdict types, extracted structured form, actual value with citation, percent delta, and notes it replaces multiple sequential calls. No contradiction.

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?

Description is dense (approx. 150 words) but well-structured: core function first, then usage guidance, then scope, then output details. Every sentence adds value; no fluff.

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 tool with comprehensive annotations and no output schema, the description fully covers what the tool does, when to use it, its scope, and output format. Complete and 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?

Schema has 100% coverage for the single parameter 'claim' with a good description. The tool description reinforces by providing example claim formats and clarifying scope (company-financial). Adds value beyond schema.

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

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

The description clearly states it verifies natural-language claims against authoritative sources, provides example trigger phrases, and specifies it handles company-financial claims. This distinctly sets it apart from sibling tools like 'ask_pipeworx_grounded' or 'entity_profile'.

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 'Use whenever the agent needs to check whether something a user said is factually correct.' It defines the scope (company-financial claims for US public companies), implying when not to use. Could be more explicit about exclusions, but adequate.

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