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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains that 'Executing each command creates a new bash process' and describes the asynchronous nature, but lacks details about error handling, security implications, resource consumption, or what the tool returns. It mentions 'Synchronous execution requires to wait the scripts completed' which helps contrast behaviors, but more operational transparency would be beneficial for a tool executing arbitrary shell scripts.

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 appropriately sized at 6 sentences. It's front-loaded with the core purpose, then explains the asynchronous nature and benefits, and ends with usage guidance. Some sentences could be more concise (e.g., 'Synchronous execution requires to wait the scripts completed' could be simplified), but overall it's well-structured with minimal 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 complexity of executing arbitrary shell scripts with no annotations and no output schema, the description is incomplete. It explains the asynchronous nature and provides usage guidance, but lacks critical information about security considerations, error handling, return values, or execution environment. For a tool that could have significant side effects, more comprehensive context is needed despite the good usage guidelines.

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 50% (only 'command' has a description in the schema, while 'options' and its nested properties lack schema descriptions). The tool description provides no parameter information beyond what's implied by the tool's purpose. The description doesn't mention any parameters, their meanings, or how they affect execution, so it doesn't compensate for the schema coverage gap. With 2 parameters and low schema coverage, this represents a significant documentation gap.

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

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

The description clearly states the tool 'executes shell scripts asynchronously in bash', providing a specific verb ('executes') and resource ('shell scripts'). It distinguishes from the sibling tool 'execute-bash-script-sync' by mentioning it in the last sentence, though the differentiation is more about usage preference than functional distinction. The purpose is clear but could be more specific about what 'asynchronously' means operationally.

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 on when to use this tool versus alternatives. It states 'Avoid using execute-bash-script-sync tool unless you really need to, and use this execute-bash-script-async tool whenever possible.' It also explains the benefit of asynchronous execution for parallel processing and reducing waiting time, giving clear context for when this approach is advantageous.

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 full burden. It discloses key behavioral traits: 'Executing each command creates a new bash process' and 'Synchronous execution requires to wait the scripts completed.' However, it lacks details about error handling, output format, security implications, or system resource usage. For a potentially dangerous tool like bash script execution with no annotations, this is a moderate disclosure level.

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 6 sentences with some redundancy ('synchronous execution' mentioned twice) and could be more front-loaded. The first sentence states the purpose clearly, but subsequent sentences mix behavioral details with usage guidelines in a somewhat disorganized way. It's not excessively verbose but could be more 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?

Given this is a potentially dangerous tool (bash script execution) with no annotations and no output schema, the description provides moderate context. It covers the synchronous nature and sibling comparison well, but lacks critical details like what happens on script failure, what output is returned, security warnings, or performance implications. For a tool with this complexity and risk profile, the description should do more.

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 50% (2 parameters total, with 'command' well-described but 'options' object lacking overall description). The description adds no parameter semantics beyond what's in the schema - it doesn't explain what 'command' should contain or how 'options' affect execution. With moderate schema coverage, the description doesn't compensate enough, resulting in a baseline 3 score.

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 shell scripts synchronously in bash' with specific verb+resource. It distinguishes from the sibling tool by mentioning 'synchronous execution requires to wait the scripts completed' and contrasting with 'asynchronous execution makes it possible to execute multiple scripts in parallel.' However, it doesn't explicitly name the sibling tool in the purpose statement, keeping it at 4 rather than 5.

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

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

The description provides explicit guidance on when to use this tool vs alternatives: 'Avoid using this execute-bash-script-sync tool unless you really need to, and use the execute-bash-script-async tool whenever possible.' It also explains the trade-off: synchronous execution requires waiting, while asynchronous allows parallel execution to reduce waiting time. This is comprehensive guidance with clear alternatives.

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