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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions pagination, which is useful, but fails to describe critical traits: whether this is a read-only operation, if it requires specific permissions, rate limits, or what the return format looks like (e.g., structured logs). For a tool with no annotation coverage, this is a significant gap 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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by a structured 'Args:' section. There is no wasted text, and each sentence earns its place by providing essential information concisely.

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 (a tool for retrieving syscall logs with pagination), no annotations, and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., read-only nature, error handling), output format, and usage context. This leaves significant gaps for the agent to understand how to invoke and interpret results effectively.

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 must compensate. It adds meaningful semantics for all three parameters: 'session_id' is explained as 'The session ID', 'offset' as 'Start index (default 0)', and 'limit' as 'Max entries to return (default 100)'. This clarifies purpose and defaults beyond the bare schema, effectively compensating for the lack of 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 tool's purpose: 'Get recorded syscall invocations with pagination.' It specifies the verb ('Get') and resource ('recorded syscall invocations'), and mentions pagination as a key feature. However, it does not explicitly differentiate from sibling tools like 'get_trace' or 'diff_trace', which might also involve syscall data, leaving some ambiguity in sibling context.

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 no guidance on when to use this tool versus alternatives. It lacks context about prerequisites (e.g., needing an active session or enabled tracing), exclusions, or comparisons to siblings such as 'get_trace' or 'hook_syscall'. This absence leaves the agent without clear usage directives.

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