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

With no annotations, the description fully relies on itself to disclose behavior. It explicitly mentions that a timestamped backup is written before deletion unless checkpoint=false, which is key behavioral detail. However, it does not mention error handling or side effects like file modification.

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 very concise and well-structured: a one-sentence purpose, a key behavioral note about backups, then a clean parameter list. No unnecessary words or redundancy.

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 tool's complexity (3 parameters, no annotations, output schema exists), the description adequately covers the main action, backup behavior, and parameter meanings. It lacks information about return values (though output schema exists) and potential errors, but is fairly complete for a simple deletion tool.

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

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

The description compensates for 0% schema coverage by providing clear, complete explanations for all three parameters: notebook_path (relative path), cell_index (zero-based), and checkpoint (default true with backup behavior). This adds significant value over the raw 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 deletes a cell from a notebook, specifying the action and resource. It distinguishes itself from siblings like notebook_edit_cell or notebook_insert_cell, which have different purposes.

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 deletion but does not explicitly differentiate from alternatives (e.g., editing or clearing a cell) or state when not to use the tool. No guidance on prerequisites or context is given.

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 provided, the description carries the full burden. It discloses the backup behavior (timestamped .checkpoint_*.ipynb) and the checkpoint parameter to disable it. However, it does not mention potential side effects like kernel state changes, file locking, or error scenarios, leaving gaps in transparency.

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: two sentences plus bullet-pointed args. Every sentence adds value. The action is front-loaded, and the args are clearly listed with context. No wasted words.

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

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

The tool has an output schema (not shown) which likely documents return values, reducing the burden on the description. The description covers the main behavioral aspect (backup) and parameter semantics. It lacks details on error handling, permission requirements, or cell existence checks, but overall provides sufficient context for a write operation.

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 0% description coverage, but the tool description adds valuable semantics for all parameters: notebook_path is relative to workspace root, cell_index is zero-based, source is new text, checkpoint defaults to true and controls backup. This compensates fully for the schema's lack of 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 starts with 'Replace the source of a cell', a clear verb-resource action. The verb 'replace' and resource 'source of a cell' accurately describe the core function, and it distinguishes from sibling tools like notebook_delete_cell or notebook_edit_cell_metadata.

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

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

No explicit guidance on when to use this tool versus alternatives. For instance, it does not mention that notebook_edit_cell_metadata should be used for metadata edits, or that notebook_read_cell is for reading. The absence of when-not or alternative recommendations reduces agent decision quality.

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 mentions the 'checkpoint' parameter for backups and describes merge behavior, but does not cover error handling, permissions, or whether the merge is deep or shallow. Some behavioral aspects are disclosed but not comprehensively.

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

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 that an output schema exists, the description covers core functionality and parameters well. However, it lacks details on edge cases like invalid cell_index or notebook_path, and does not explain the return behavior beyond the output schema's presumed role.

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

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

Schema description coverage is 0%, so the description fully compensates. Each parameter (notebook_path, cell_index, updates, checkpoint) has a clear, descriptive explanation that adds meaning beyond type and name, including examples and defaults.

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 merges a JSON object into a cell's metadata, with an example for pipeline tags. The name 'notebook_edit_cell_metadata' combined with the description makes the purpose clear, but it does not explicitly distinguish from sibling tools like 'notebook_edit_metadata' which edits notebook-level metadata.

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?

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 3 parameters, no annotations, but an output schema exists. The description covers parameters and side effects (backup). It is mostly complete, though missing error handling and path validation details. Return values are handled by the output schema, so no deduction needed.

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 descriptions are missing (0% coverage), so the description compensates well. It explains notebook_path (relative path), updates (JSON string for top-level keys), and checkpoint (boolean for backup). Could be more precise on updates structure, but it adds value beyond the schema.

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

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

The description implies usage by detailing the operation (insert) and behavioral notes (shifting, appending), but it does not explicitly mention when to use this tool versus alternatives or provide exclusions.

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

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

With no annotations provided, the description carries full burden. It mentions the output (absolute paths) but does not disclose any behavioral traits like side effects, performance, or whether it is read-only. For a 0-parameter list operation, this is adequate but not exhaustive.

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 consists of two concise, front-loaded sentences. Every sentence adds value: the first explains the purpose, the second details the return format.

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 tool has 0 parameters and an output schema exists, the description is sufficiently complete. It clearly defines what the tool does and what it returns, leaving no major gaps.

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

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

The description clearly states the verb 'list', the resource 'notebooks with running kernels', and the scope 'in this session'. It also specifies the return value (absolute resolved paths), which distinguishes it from siblings like notebook_list_kernels.

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 when needing to find notebooks with active kernels, but does not explicitly state when to use this tool versus alternatives such as notebook_list_kernels. No guidance on when-not-to-use is provided.

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 description carries full burden. While it implies a read-only list operation, it does not explicitly state that no side effects occur or that it is safe to call multiple times. More explicit safety disclosure would improve score.

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

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

Two short sentences plus an argument description. Front-loaded with key result details. No wasted words.

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 specific verb 'list every cell' and identifies the resource as a notebook, detailing what is returned (index, type, tags, first line). This clearly distinguishes it from sibling tools that modify or read individual cells.

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 states 'Call this first to understand the structure before reading or editing specific cells,' providing clear when-to-use guidance and implied exclusion of direct cell manipulation.

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 provided, so description carries full burden. It discloses return format (dict of name to display name) and potential module issues with solution. However, it doesn't mention any permissions or failure modes beyond that.

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 covers the core purpose and parameter semantics, but does not address error conditions (e.g., file not found, invalid notebook) or result structure. An output schema exists, mitigating return format concerns, but error handling is missing. For a simple read tool, it is adequate but not fully 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 schema provides only type and required for the single parameter. The description adds clear meaning: 'Path to the .ipynb file, relative to the workspace root.' This compensates fully for the missing schema 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 verb 'Read' and the resource 'top-level notebook metadata' with examples (kernelspec, language_info). This distinguishes it from sibling tools like notebook_edit_metadata (write) and notebook_read_cell (read cell content).

For a simple tool with one required parameter and an output schema, the description fully explains the action, behavioral nuance, and parameter meaning. 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?

The schema has 0% description coverage, so the description must compensate. It defines the parameter 'notebook_path' as path to the .ipynb file, which adds clarity beyond the schema's title 'Notebook Path'.

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 'Restart the kernel for a notebook, clearing all variables and imports.' This is specific and distinct from sibling tools like cell editing or pipeline runs.

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?

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

The description discloses key behaviors: it saves outputs back to the notebook file (save_outputs), stops on error by default (stop_on_error), and has per-cell timeout. Since no annotations are provided, the description carries the full burden and covers important side effects (writing to file) and execution semantics.

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 highly concise: a single sentence defining the tool's purpose followed by a bullet list of all five parameters with defaults and explanations. No redundant text; every sentence adds value. Information is 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?

Given the tool has 5 parameters, no annotations, and an output schema (assumed to cover return values), the description adequately explains all parameters and core behavior. However, it lacks details on output format, error handling beyond stop_on_error, and any performance or state implications (e.g., kernel reset).

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?

While the description attempts to explain each parameter, it inaccurately states the default for kernel_name as 'python3' when the input schema specifies default null. This contradiction misleads the agent about the tool's actual default behavior. Schema description coverage is 0%, so accurate parameter documentation is critical.

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 'Execute every cell in the notebook in order and return all outputs,' which specifies the verb (execute), resource (every cell in the notebook), and scope (in order, all outputs).

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 does not provide any guidance on when to use this tool versus alternatives. It lacks explicit 'when-to-use' or 'when-not-to-use' conditions, and does not mention any prerequisites or context for preferring full notebook execution over running individual cells or ranges.

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 burden. It discloses that kernel state is preserved, outputs are returned, and save_outputs controls writing back to file. It does not explicitly state if the operation is destructive, but the nature of executing code implies mutation. The description adequately covers 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.

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 many sibling tools, the description clearly identifies this tool's role. It covers key aspects: execution behavior, parameter details, and output. The presence of an output schema means return values need not be explained. The description is sufficiently complete for correct tool selection and 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 description coverage is 0%, but the description fully explains each parameter in the Args section, adding meaning beyond the schema. It clarifies paths, indices, kernel options, timeout, and save behavior, which is excellent compensation.

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 executes a single code cell and returns outputs, which is a specific verb+resource. It distinguishes from siblings like notebook_run_all or notebook_run_range.

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 explains that kernel state is preserved and cells can depend on earlier ones, providing context for when to use. It also suggests using notebook_list_kernels for kernel options. However, it does not explicitly mention when not to use this tool compared to alternatives like run_range.

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 that the tool runs cells in notebook order, optionally saves outputs back to the file (save_outputs), stops on error (stop_on_error), and uses a specified kernel. It does not mention any destructive actions beyond saving outputs, which is explicitly controlled by a parameter.

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 introductory sentence, a note on setting tags, a sibling tool reference, and a clear 'Args:' section. It is efficient, but could be slightly more condensed without losing clarity. Still, it earns its sentences and is 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?

Given the tool's complexity (6 parameters, 2 required) and the presence of an output schema, the description is fairly complete. It explains all parameters, the execution order, and provides a pointer to a related tool. It does not cover return values, but that is acceptable since an output schema exists. Minor gaps like error handling beyond stop_on_error are covered by the parameter description.

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 0% description coverage, so the tool description compensates fully. It provides clear, meaningful explanations for all six parameters, including defaults (e.g., 'Kernel to use (default: 'python3')') and behavior ('Stop at first failing cell (default: true)'). This adds essential context beyond the schema alone.

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 'Run all cells tagged with a pipeline stage, in notebook order.' It specifies the verb (run), resource (cells tagged with a stage), and behavior (order). It also explains how to set tags and distinguishes itself from siblings like notebook_run_all and notebook_run_cell.

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 explicit guidance to 'Use notebook_list_stages to see what stages exist in a notebook,' indicating when to use this tool versus that alternative. It does not explicitly state when not to use the tool, but the sibling context and the detailed parameter explanations imply appropriate usage.

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

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

Describes default stop_on_error, timeout, and save_outputs behavior. Lacks details on kernel instantiation, side effects (e.g., kernel state), and output format. Adequate but not thorough.

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 lead sentences plus a clear bulleted arg list. Every sentence adds value; no redundancy. Well-structured for quick scanning.

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

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

Covers core functionality and all parameters. Does not describe output schema or kernel prerequisites, but output schema exists externally. Slightly incomplete for a parameter-rich 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?

With 0% schema coverage, the description explains all 7 parameters with defaults and semantics (e.g., 'relative to workspace root,' 'per-cell timeout'). Adds value but lacks some format constraints.

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

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

The description clearly states 'Execute cells from start to end (inclusive) and return all outputs,' specifying verb, object, and range. This distinguishes it from siblings like notebook_run_all and notebook_run_cell.

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

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

No explicit guidance on when to use this tool versus alternatives (e.g., notebook_run_all, notebook_run_cell). Does not explain trade-offs or exclusion conditions.

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