opn_update_dnsmasq_range

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

With no annotations, the description discloses that after update the service is automatically reconfigured and changes take effect immediately. It also explains that only provided parameters are changed. No mention of permissions or error handling, but the behavioral impact is clear.

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?

Well-structured: opening statement, usage note, parameter list, return info. The parameter list is somewhat lengthy but each entry is necessary. Conciseness could be improved by grouping optional params, but overall it's readable.

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 (9 params, no annotations, update operation), the description is thorough. It covers partial update semantics, service reconfiguration, use of UUID, and return value. Only minor gaps like error handling, but sufficient for an agent.

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 9 parameters are listed with explanations and examples (e.g., 'lease_time: lease duration (e.g. '24h', '1h')'). Since the schema has no descriptions, the description fully compensates with meaningful semantics.

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 'Update a dnsmasq DHCP range by UUID and apply the configuration.' It specifies the verb (update), resource (dnsmasq DHCP range), and distinguishes from siblings like add and delete by focusing on change.

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 'Use this when you need to change...' and advises to 'Use opn_list_dnsmasq_ranges first to find the UUID.' It mentions partial updates ('Only parameters you provide are changed'). However, it does not explicitly state when not to use it or compare to related tools like opn_reconfigure_dnsmasq.

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