Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.0
Disambiguation4/5
Tools are mostly distinct, covering different data types (quotes, indices, deals, insider trading, etc.). However, the multiple bulk-deal tools (get_bulk_deals, get_latest_bulk_deals, get_top_bulk_buys, get_top_bulk_sells) could cause confusion as they overlap in purpose but differ in sorting/filtering.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern using snake_case (e.g., get_quote, search_by_symbol, get_top_gainers). There is no mixing of conventions or ambiguous naming.
Tool Count4/5
With 17 tools, the count is slightly above the typical well-scoped range, but each tool serves a clear purpose covering a breadth of NSE data. A few could be consolidated (e.g., the bulk-deal variants), but overall it's reasonable for the domain.
Completeness4/5
The tool set covers many essential NSE data points: quotes, indices, market status, top movers, bulk/block deals, insider trading, FII/DII activity, short selling, announcements, and corporate actions. Missing historical data and fundamental analysis, but the core real-time and regulatory data is well covered.
Average 3.6/5 across 17 of 17 tools scored. Lowest: 3/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, rate limits, pagination, result ordering, or any side effects. The description only covers content, not behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two informative sentences with no filler; purpose is front-loaded. Could be slightly improved by adding usage cues without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with no required parameters and no output schema, the description provides adequate purpose but lacks behavioral details and contextual completeness given the absence of annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description adds no additional meaning beyond the schema. Baseline score of 3 is appropriate as it does not repeat but also does not enhance parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves corporate announcements from NSE, listing types (board meetings, results, dividends, mergers, etc.) and draws an analogy to SEC EDGAR 8-K filings, making the tool's purpose immediately understandable and distinct from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives like search_by_symbol or get_corporate_actions. The description lacks usage context, prerequisites, or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but does not disclose behavioral traits such as read-only nature, latency, rate limits, or data freshness beyond 'today's'. It mentions fetching but lacks explicit safety or performance context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: a single sentence with an appended clause provides all key information. No wasted words, front-loaded with the core action and context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 optional params, no output schema), the description covers the main purpose, data returned, and filters. It lacks mention of time precision (e.g., real-time vs. end-of-day) or pagination, but is mostly complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with adequate descriptions for both parameters. The description adds marginal context (e.g., counterparty, quantity, trade price) beyond the schema, but does not significantly enhance parameter understanding. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb (Fetch) and resource (today's NSE block deals), with specific details about minimum value and data fields. While it does not explicitly distinguish from sibling tools like get_bulk_deals, the context of 'Block Deal Window' implies a distinct category.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, no when-not or prerequisites provided. The description only states the basic action, leaving the agent without context for appropriate invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist. Description discloses resource and metric but omits behavioral traits like output format, ordering, or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key details, no extraneous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Minimal description for a simple tool. No output schema provided, so description could elaborate on return values or sorting, but current session context is useful.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with parameter descriptions. The description adds temporal context ('current session') but does not significantly extend understanding of parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool retrieves top losing NSE stocks by percentage change for the current session within a given index, distinguishing it from siblings like get_top_gainers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when or when not to use this tool relative to siblings. Usage is only implied by the description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully cover behavioral traits. It only states the tool returns top bulk-deal sales, but does not disclose that it is read-only, the time horizon ('today's' is ambiguous), or any limitations like rate limits or authentication needs. The description is too sparse for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences with no extraneous information. It is front-loaded with the main purpose and adds a use case in the second sentence. Every word serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of sibling tools (e.g., get_bulk_deals, get_top_bulk_buys) and lack of output schema, the description is minimal. It does not explain the returned fields, data source, or whether 'today's' refers to the current trading day. The description is adequate for a simple list but lacks details needed for informed selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema for the parameters (limit and symbol). It does not explain how they affect the ranking or filtering beyond what the schema already says.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool returns 'Today's largest bulk-deal sales ranked by total trade value.' It specifies the resource (bulk-deal sales), action (get top), and sorting (by total trade value), distinguishing it from related sibling tools like get_top_bulk_buys.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'Useful for spotting institutional distribution,' which gives a use case. However, it does not explicitly state when not to use this tool or compare it to alternatives like get_bulk_deals or get_top_bulk_buys. The guidance is implied but not fully explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of disclosing behavior. It states 'current session' indicating real-time data, but does not mention data freshness, update frequency, or any limitations. No indication of read-only or destructive nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no wasted words. It is front-loaded with the key purpose and perfectly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no output schema, so the description could be more complete by explaining the return format (e.g., list of stocks with percentage change). It is adequate for a simple list but leaves the agent to guess the output structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for both parameters, so the schema already documents them fully. The description adds no additional meaning beyond what the schema provides. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly specifies the verb 'get', the resource 'top gaining stocks', the metric 'percentage change', the timeframe 'current session', and the scope 'within a given index'. It effectively distinguishes from sibling tools like 'get_top_losers' and 'get_most_active'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives. No explicit when-not or examples of preferred scenarios, despite having many sibling tools. The agent must infer usage from context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It indicates the tool is read-only and time-bound ('today's'), but lacks details like rate limits, data availability, or error conditions. Misses some behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with key action, no extra words. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, but description lists returned fields (buyer/seller, quantity, price). For a simple tool, this is fairly complete; could mention pagination or limits.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. Description adds context about 'today's' but does not enrich parameter meaning beyond schema (e.g., date format for symbol filter).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it fetches today's NSE bulk deals, explains the criteria (≥0.5% of listed shares), and distinguishes from siblings like get_block_deals. Verb is specific ('Fetch') and resource is well-defined ('NSE bulk deals').
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives such as get_block_deals or get_latest_bulk_deals. No explicit context on when not to use it or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only mentions 'current session' but fails to clarify data freshness, rate limits, pagination, or return format, leaving significant gaps for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-front-loaded sentence with no wasted words. It efficiently conveys the core function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 optional params, no output schema), the description adequately covers purpose and key metric. It lacks details on sorting order or update frequency, but remains sufficient for a basic list tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Since schema description coverage is 100% and both parameters have descriptions in the schema, the description adds no additional meaning beyond what is already provided. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'get' and the specific resource 'most actively traded NSE stocks by total traded value (₹) in the current session', distinguishing it from sibling tools like get_top_gainers or get_top_losers which focus on different metrics.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving actively traded stocks by value but does not provide explicit guidance on when to use this tool versus siblings, nor does it mention any exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; the description only states the output content, not behavioral traits like read-only nature, error handling when market closed, or rate limits. Full burden on description, which is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key information. No wasted words. Ideal conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description provides general content but lacks specific structure details. For a simple status tool, this may be adequate, but it could be more complete by describing the output format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so schema coverage is 100% trivially. The description doesn't need to add parameter info. Baseline score of 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it returns NSE market status for specific segments (Capital Market, F&O, Currency Derivatives, Commodity) and live index levels. This distinguishes it from siblings like get_quote or get_nifty_indices.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for checking overall market status, but no explicit guidance on when to use vs alternatives like search_by_symbol or get_quote. No 'when not to use' or alternatives mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It describes the data returned (price, change, etc.) and implies 'live' data, but does not disclose caching, authentication requirements, rate limits, or real-time nature. A 3 is appropriate as it offers some behavioral context but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that lists key examples and data fields. It is front-loaded with purpose, but could be more structured (e.g., separate lines for return fields). No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one optional parameter and no output schema, the description adequately explains what data is returned (price, change, 52-week range, advances/declines) and the scope (all NSE indices). It is missing details like default behavior with no filter, but overall sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (the sole parameter 'name' is fully described in the schema). The description does not add any additional semantic value beyond the schema, so it meets the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Live data for all NSE indices' and lists specific examples (Nifty 50, Nifty Bank, etc.) and data fields (price, change, 52-week range, advances/declines). This distinguishes it from siblings like get_quote or search_by_symbol, which target individual symbols or different data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for retrieving index data, but it does not explicitly state when to use this tool versus alternatives like get_quote or search_by_symbol. No usage scenarios or exclusions are provided, leaving the agent to infer from context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral aspects. It discloses the types of actions and dates included but does not mention data freshness, response size, or any limitations. It is adequate but lacks depth; 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (two sentences), front-loaded with the main purpose, and no redundant information. Every word contributes to understanding the tool's output and scope.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description effectively explains the tool returns dates for corporate actions. It covers the main use case but does not describe the response format or how to interpret the data, which would be helpful for complex actions like splits. Still, it is relatively complete for a list tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage for all three parameters (symbol, toDate, fromDate). The description adds no additional semantic value beyond the schema's own descriptions. Baseline 3 is appropriate as schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool's purpose: retrieving upcoming and recent corporate actions. It lists specific action types (dividends, stock splits, etc.) and key dates (ex-date, record date, payment date), distinguishing it from sibling tools like get_quote or search_by_symbol.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for fetching corporate actions but does not explicitly state when to use this tool versus alternatives. No guidance on when to omit or include the symbol parameter, though it is implied by the schema. Sibling tools are diverse, so more explicit differentiation would help.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description should disclose behavioral traits. It mentions that data is daily for the Indian cash market, but it does not specify latency, authentication requirements, rate limits, or how missing data is handled. This lack of detail reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, consisting of two short sentences that immediately convey the tool's purpose and context. No unnecessary words or redundant details are present.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one optional parameter and no output schema, the description adequately covers the data source (FII/DII net figures) and its significance. It could be improved by mentioning the historical nature implied by the 'limit' parameter, but it is mostly complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% coverage for the single 'limit' parameter, which is already well-documented in the schema. The description adds no additional parameter information, meeting the baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool's function: returning daily net buy/sell figures for FII and DII in the Indian cash market. It also highlights its relevance as a key macro signal, differentiating it from other sibling tools that focus on quotes, indices, or bulk deals.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description states that the tool provides a key macro signal for market direction, implying use for directional analysis. However, it does not explicitly mention when to avoid using it or compare it to alternatives, so a moderate score is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Describes read-only fetch and output fields, but lacks info on pagination, rate limits, or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with purpose, concise and no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple fetch tool with no required params and no output schema. Missing some transparency details but covers key output fields.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline 3. Description adds minimal value beyond schema (e.g., 'Filter by NSE symbol' is already in schema). Does not explain defaults or format beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it fetches SEBI PIT disclosures with specific details (promoter/insider, buy/sell, acquirer name, category, shares before/after, mode). Distinguishes from sibling tools like bulk/block deals.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use vs alternatives. Usage is implied by the tool name and description, but no guidance on when to choose over siblings like get_bulk_deals.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses that the tool returns data, sorts by trade value, and optionally filters by direction. However, it does not explicitly state that it is read-only or idempotent, nor does it mention any potential side effects, rate limits, or pagination behavior. The transparency is adequate for a simple wrapper but could be improved.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 15 words, highly concise, and front-loaded with the key phrase 'Convenience wrapper'. Every word contributes meaning; there is no redundant or extraneous text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one optional parameter, no output schema), the description adequately covers the core functionality: returning today's deals, sorted, optionally filtered. It could hint at the return structure (e.g., fields like symbol, value) but is largely complete for a wrapper. Sibling tools with more parameters may have richer descriptions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a description for 'dealType' that already explains the filtering. The description's mention of 'optionally filtered by direction' adds no new meaning beyond the schema. Thus, the description does not compensate further, scoring the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it is a convenience wrapper that returns today's bulk deals sorted by trade value, optionally filtered by direction. This specific verb and resource combination distinguishes it from siblings like 'get_bulk_deals' (which likely returns all without sorting/filtering) and 'get_top_bulk_buys'/'get_top_bulk_sells' (which filter by direction already).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'Convenience wrapper' implies it is a simplified alternative to 'get_bulk_deals', but it does not explicitly state when to use this tool versus the more specific siblings like 'get_top_bulk_buys' or 'get_top_bulk_sells'. There is no guidance on when not to use it or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It mentions the data source and reporting framework but does not disclose behavioral traits such as data recency, update frequency, or any limitations (e.g., historical depth).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-constructed sentence that efficiently conveys the tool's purpose and data source without any superfluous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (two optional parameters, no output schema) and the context of 17 sibling tools, the description provides sufficient information for an AI agent to understand the tool's role. However, it could be more complete by noting the absence of time periods or units.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both parameters. The description adds minimal extra meaning beyond the schema, stating that 'limit' returns top N by short-sold quantity and 'symbol' filters by NSE symbol. This is adequate but does not significantly enhance understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as providing NSE short-selling data, including quantity of shares sold short and second-leg covering quantities, as reported under SEBI's framework. This is specific and distinguishes it from sibling tools like search_by_symbol, get_quote, and get_top_gainers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus alternatives. It implies it is for accessing short-selling data but provides no guidance on scenarios where other tools might be more appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description carries full burden. It discloses ranking criterion and time scope ('today's'), and adds context about purpose. However, it does not mention mutability, rate limits, or data freshness, and could be more explicit about being read-only.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with core functionality in first sentence, second adds valuable context. No extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema or annotations, description adequately explains what the tool returns (top buys, ranked by value, today-only) and its utility. Could be slightly more complete by explicitly noting NSE context and that it is only for purchases, but overall strong.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Parameter descriptions in the schema already cover 'limit' and 'symbol' with default and NSE scope. The tool description adds no extra parameter information. Since schema coverage is 100%, baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it returns 'today's largest bulk-deal purchases ranked by total trade value (quantity × price)', which is specific and distinguishes from sibling tools like get_top_bulk_sells by specifying 'purchases' and 'institutional accumulation'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description provides a use case ('spotting institutional accumulation') but lacks explicit guidance on when not to use or how it compares to siblings like get_bulk_deals or get_top_bulk_sells. The usage is implied but not fully directive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It states the tool returns today's deals and recent insider trades/announcements, but does not cover authentication, error behavior, or data freshness. Basic behavioral context is present but incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that front-loads the key purpose ('Aggregate view for a single NSE stock') and efficiently lists the included data types. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 2 parameters and no output schema, the description provides a clear list of what is returned. It does not explain the return format or pagination, but for an aggregate view tool, the stated coverage of deals and announcements is fairly complete for selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond what is already in the schema (symbol required, daysBack optional). It does not clarify format or constraints beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it returns an aggregate view for a single NSE stock, listing specific data types (bulk deals, block deals, insider trades, announcements). This distinguishes it from sibling tools that focus on individual data types.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly indicates when to use: for an aggregate view of a single NSE stock. It implies that if only one data type is needed, sibling tools should be used, but it does not explicitly state exclusions or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states the source (Yahoo Finance) and currency (INR), and implies 'live' data, but does not disclose data freshness, rate limits, or potential side effects. For a read-only quote tool, this is adequate but could be more explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no unnecessary words. Front-loaded with core purpose, then specifics, then currency. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (1 param, no output schema, no annotations), the description covers the key use case and returned fields. It could mention error handling or possible delays in live data, but overall it is complete enough 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.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The lone parameter (symbol) is already well-documented in the schema (100% coverage). The description adds significant value by explaining that .NS is appended automatically and that .BO queries BSE, providing crucial usage context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides live stock quotes from Yahoo Finance for NSE-listed stocks, and lists specific data fields (price, 52-week range, volume, etc.). This distinguishes it from sibling tools like search_by_symbol or get_market_status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for getting detailed quote data for NSE stocks, but does not explicitly state when to use this tool versus alternatives (e.g., search_by_symbol for just symbols, or get_nifty_indices for index data). No guidance on exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
