proxy_update_rule

Update an existing interception rule to change its matcher, handler, priority, or description. Adjust how network traffic is captured, mocked, or modified without deleting and recreating the rule.

Instructions

Modify an existing interception rule.

Behavior2/5

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

No annotations provided, so description must disclose behavior. Fails to clarify if update is partial or full replacement, what happens on invalid rule_id, or whether changes take effect immediately. Lacks side-effect details.

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

Conciseness2/5

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

At 4 words, the description is too brief for a tool with 5 parameters including nested objects. It sacrifices clarity for brevity; should at least mention updatable fields or behavior.

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

Completeness2/5

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

No output schema and no return value description. Missing guidance on success/failure signals, error conditions, or what the tool returns. Incomplete for a mutation tool in a complex domain.

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

Parameters3/5

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

Input schema covers 100% of parameters with descriptions, so baseline is 3. Description adds no additional meaning beyond the schema; it does not explain partial update semantics or required fields beyond rule_id.

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

Purpose5/5

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

Description 'Modify an existing interception rule' uses a specific verb (modify) and resource (existing interception rule), clearly distinguishing from siblings like proxy_add_rule (create), proxy_remove_rule (delete), and proxy_enable_rule/proxy_disable_rule.

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

Usage Guidelines2/5

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

No guidance on when to use this tool vs alternatives. Does not mention that proxy_add_rule should be used for new rules or proxy_remove_rule for deletion. Lacks context on prerequisites or best practices.

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