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

With no annotations provided, the description carries the burden of behavioral disclosure. It clearly states that it returns scores for five dimensions and detects First Principles indicators, with definitions for each dimension. This gives the agent an accurate understanding of what the tool computes and outputs, though it doesn't explicitly state that it's a read-only operation.

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 and front-loaded with the primary purpose, followed by a clear bulleted list of dimensions. It is slightly redundant in mentioning 'First Principles' indicators after already covering 'Building from Scratch' in the bullet list, but overall each 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?

The tool has an output schema, so return values are covered separately. The description adds context about the scoring dimensions, making it clear what the analysis emphasizes. It is sufficiently complete for a non-destructive analysis tool, though it could mention potential limitations or data sources beyond GitHub.

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

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

Schema description coverage is 100%, so the input schema already fully documents all four parameters. The description adds no additional parameter-specific details beyond the schema, which is acceptable given high schema coverage, but it does not enhance parameter understanding.

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 ('Analyze') and a well-defined resource ('GitHub contributions against the Andrej Karpathy Skills framework'). It clearly differentiates from sibling tools by covering all five skill dimensions at once, whereas siblings like scan_first_principles and detect_attention_to_detail focus on single dimensions.

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: it is for analyzing contributions against the full Karpathy framework, which implies when to use it. However, it does not explicitly mention when NOT to use it or point to alternative sibling tools, so it stops short of full 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?

No annotations are provided, so the description carries the full burden. It discloses the evaluation criteria (7 checks) and the return format (bonus points, anti-pattern flags, checklist), which is useful behavioral context. However, it does not state whether the tool is read-only, requires any authentication, or has side effects, leaving a notable gap 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.

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

The description is well-structured with a brief intro followed by a bulleted checklist. It is front-loaded with the purpose, and every line adds value. No fluff or redundant 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?

The description explains what the tool does, what exact checks it performs, and what it returns. Since an output schema exists, return details are covered elsewhere. The main missing element is usage guidance and explicit caveats, but overall the description covers the core behavior quite well for a moderately complex analysis 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?

Schema description coverage is 100%, meaning every parameter already has a description. The tool description adds no additional semantics about how parameters like 'repo', 'since', 'until', or 'username' influence the analysis. Per the guideline, baseline 3 applies when schema does the heavy lifting.

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 opens with a specific verb ('detect') and resource ('attention-to-detail'), then enumerates a concrete checklist of criteria (README, CHANGELOG, tests, commit messages, etc.). This makes the tool's purpose highly specific and clearly distinguishes it from sibling analysis tools like get_contribution_metrics or analyze_karpathy_alignment.

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 checklist implies the tool is used to assess thoroughness of code changes, which gives some contextual hint. However, there is no explicit guidance on when to use this tool versus siblings, nor any exclusions or alternative tool mentions. It is only implicitly usable.

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 must carry the burden. It explains the tool analyzes the last N weeks and returns per-dimension scores plus trends, which is useful behavioral context. However, it does not explicitly state whether the operation is read-only, has side effects, or requires any permissions.

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 sentences long, front-loaded with the main purpose, and every sentence adds value. It is concise, well-structured, and free of redundant phrasing.

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

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

The output schema exists, so return values are documented. The description covers the tool's purpose, behavior, and intended use case (feeding the dashboard). Given the tool's moderate complexity and available structured data, the description is complete.

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

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

The input schema has 100% coverage with clear descriptions for all three parameters (repo, weeks, username). The description adds a slight clarification by mentioning 'last N weeks', which maps to the weeks parameter, but this does not go beyond the schema's existing 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 the tool exports Karpathy skill evolution data for Spider Chart visualization. It specifies the resource (evolution data), the verb (Export), and adds scope with weekly analysis and trend detection, distinguishing it from siblings like get_contribution_metrics.

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 for generating spider chart visualizations and feeding the Next.js dashboard, but it does not explicitly state when to use this vs alternatives or mention any exclusions. It lacks direct comparison to sibling 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?

No annotations are provided, so the description carries the full burden. It discloses the output format (Markdown report with specific sections) but does not mention data sources, authentication requirements, or whether it performs any side effects. For a report generator, the output description adds value, but more transparency would be beneficial.

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 sentence, a targeted audience note, and a bulleted list of output sections. Every sentence adds value and the content is front-loaded, making it easy to scan.

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 report generation tool with 5 optional parameters, no annotations, and an output schema, the description covers the purpose, audience, and output structure. It lacks explicit mention of data dependencies but is otherwise complete for a tool of this complexity.

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 already provides 100% description coverage for all parameters (repo, since, until, username, client_name) with clear defaults and formats. The tool description adds no additional meaning beyond the schema, so a baseline of 3 is appropriate.

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

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

The description clearly states the tool generates a client-facing delivery report that translates technical contributions into business value, using a specific verb and resource. It distinguishes itself from sibling tools by emphasizing the audience (non-technical stakeholders) and the output format (Markdown with sections).

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 identifies the target users (freelancers, MEI, consultants) and the scenario (communicating value to non-technical stakeholders), providing clear usage context. It does not explicitly name alternatives or exclusions, but the intended use case is 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?

No annotations are present, so the description carries the burden of behavioral disclosure. It describes the report structure and that it consolidates weekly activities, which suggests a non-mutating aggregation, but it does not explicitly state side-effect safety, required permissions, or behavior when filters are omitted.

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 front-loaded with a one-sentence purpose followed by a scannable bullet list of report components. Every sentence/line adds meaningful detail and there is no filler.

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

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

For a tool with three optional parameters and a rich output schema, the description gives a solid understanding of intended use and output sections. It omits edge cases like an empty week, but the schema and output schema cover most parameter and return semantics.

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 already describes all three optional parameters with 100% coverage, so the baseline is 3. The description adds little beyond the word 'weekly' aligning with week_offset, and does not explain how repo or username would influence the summary content.

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

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

The description opens with a specific action ('Generate an executive weekly impact summary for stakeholders') and enumerates distinct deliverables (key achievements, Karpathy Skills, metrics, business value translations, spider chart data). This clearly differentiates it from siblings like get_contribution_metrics or generate_client_report.

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 context is clear: this is for a weekly executive stakeholder summary, implying a recurring cadence. However, it does not explicitly mention alternatives or state when not to use this tool versus siblings like generate_client_report.

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 does disclose the analysis nature ('identify', 'assess') and details the return structure, which is useful. However, it omits any mention of authentication, rate limits, or side effects, though the tool appears to be a read-only query. It adds some context but not rich behavioral detail.

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 concise and front-loaded with the main purpose. However, the first sentence lists three contribution types that are immediately repeated in the bullet list with the full set of seven, creating minor redundancy. Overall, it is efficiently structured.

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

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

The description adequately captures the tool's core functionality and return values, complementing the rich input schema and output schema. It lacks comparisons to sibling tools and notes on permissions or limitations, but for an analysis tool this is a minor gap.

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

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

Schema coverage is 100%, so the baseline is 3. The description does not add meaning beyond the schema's parameter descriptions (e.g., repo filter, date range), but the schema itself is clear and self-sufficient.

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 specific function: identifying contribution types and assessing their impact on codebase health. It lists detailed output fields (classification, impact level, health delta, complexity, first principles) that distinguish it from generic analytics tools like get_contribution_metrics.

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 offers no explicit guidance on when to use this tool versus its siblings (e.g., get_contribution_metrics, scan_first_principles). It only describes the output without mentioning alternatives, exclusions, or typical use cases, leaving the agent to infer.

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 that the operation is a retrieval and that returns are aggregated, which is helpful. However, there is no annotation context and the description does not mention authentication, rate limits, pagination, or potential side effects. The use of 'raw' followed by 'aggregated data' also introduces ambiguity about the true nature of the output.

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 compact: two sentences that state purpose, return content, and use case. It is front-loaded with the verb and resource, and no sentence is wasted. The minor 'raw/aggregated' tension is a semantic concern, not a structural one.

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

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

With an output schema present and full parameter documentation in the schema, the description provides sufficient context for basic use. It names the key data categories and the primary use case. It lacks explicit alternative tool references and does not clarify the 'raw' vs 'aggregated' distinction, but the presence of a robust schema compensates.

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

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

Schema coverage is 100%, so the parameters are already well-documented in the input schema. The description does add a general 'filtered by time period' clue, but it does not provide additional meaning beyond what the schema already gives for each parameter. This meets the baseline for high schema coverage.

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

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

The description opens with a clear verb ('Retrieve'), a specific resource ('raw GitHub contribution metrics'), and a scoping mechanism ('filtered by time period'). It immediately distinguishes this from sibling tools like generate_weekly_impact_summary or analyze_karpathy_alignment by emphasizing raw retrieval and specific metric categories (commits, PRs, reviews, code changes).

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 phrase 'Useful for understanding contribution volume and patterns' provides clear context on when to use the tool. However, it does not explicitly mention when not to use it or point to alternative sibling tools, so it falls short of the highest bar.

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 of behavioral disclosure. It transparently lists what it analyzes and the exact return metrics with semantics (e.g., 'Dependency Delta (negative = fewer deps = positive)'), but it does not explicitly state read-only behavior or auth requirements, though the verb 'Scan' implies non-destructive action.

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 succinct: a one-line summary, a four-item bullet list of analysis criteria, and a five-item bullet list of returns. It front-loads the primary purpose and uses structured bullets without unnecessary prose, making it easy for an agent to parse quickly.

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

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

The description provides both the analysis criteria and the return metrics, giving a complete picture of what the tool does and what to expect. Since an output schema exists, the return values are also structured, but the description alone is sufficient for an agent to decide whether to invoke 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?

All four parameters have descriptions in the schema (100% coverage), so the description does not need to re-explain them. The description does not add parameter-specific semantics beyond the schema, providing only the general context of scanning contributions. This meets the baseline for high schema coverage.

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

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

The description opens with 'Scan contributions for first-principles thinking patterns,' which is a specific verb+resource combination. The bulleted list details the exact patterns analyzed and the output metrics, clearly distinguishing this tool from siblings like 'get_contribution_metrics' and 'analyze_karpathy_alignment'.

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 clearly implies when to use the tool: to analyze PRs for first-principles thinking, listing the exact signals it looks for. However, it does not explicitly state when not to use it or mention alternative sibling tools for related analyses, so it stops short of full usage guidance.

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