local_ydb_start_dynamic_node

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

Annotations are already present, but description adds key behavior: 'Without confirm=true this returns a plan only.' This is a dry-run feature not indicated by annotations. It does not detail full execution side effects, leaving some ambiguity, but overall adds value beyond 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?

Three sentences, each serving a distinct purpose: purpose, usage context, behavioral note. No redundant or vague language. Efficient and front-loaded with key 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?

Given 3 parameters, high schema coverage, and clear annotations, the description covers usage and behavioral nuance. However, it does not describe output format or what exactly happens on successful execution (e.g., node becomes running). Minor gap but overall adequate.

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 adds context for 'confirm' (plan vs execute) and clarifies 'configPath' usage. This provides some added meaning, but mostly the schema descriptions are 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?

Description clearly states 'Start the configured primary dynamic tenant node for an existing CMS tenant.' It uses a specific verb and resource, and distinguishes itself from sibling tool 'local_ydb_add_dynamic_nodes' by noting that the sibling is for extra nodes.

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 says when to use: 'Use after local_ydb_create_tenant or when admin status is PENDING_RESOURCES', and when to use alternative: 'use local_ydb_add_dynamic_nodes for extra nodes'. Also explains the confirm parameter behavior.

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