ipc_monitor

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

Annotations already declare the safe/idempotent profile (destructiveHint=false, idempotentHint=true), so the description adds value by disclosing scope: it captures invoke() calls via window.__TAURI__.core and excludes bridge-internal commands (plugin:mcp-bridge|*). It does not describe what 'stop' does to buffered captures or how captured data is retrieved, leaving a small gap.

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?

Dense and front-loaded: the domain constraint leads, prerequisites follow, then capture scope, then the alternative. Every clause carries information and nothing is redundant.

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?

No output schema exists, yet the description never explains how captured calls are surfaced (presumably via ipc_get_captured), which an agent needs to complete the start/monitor/retrieve workflow. Otherwise prerequisites, scope, and exclusions are sufficient for a 2-parameter tool.

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 100%, so the schema already documents both 'action' (start/stop enum) and 'appIdentifier'. The description adds no parameter-level meaning beyond that, so the baseline of 3 applies.

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?

States a specific verb and resource ('Monitor Tauri IPC calls between frontend and Rust backend') and immediately marks the domain with '[Tauri Apps Only]'. An agent can distinguish it from siblings like ipc_execute_command or ipc_get_captured without opening the schema.

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?

Gives clear prerequisites ('Requires active driver_session') and a routing exclusion ('for browser network monitoring, use Chrome DevTools MCP'). It does not explicitly contrast with the closest siblings (ipc_get_captured, ipc_execute_command), so it stops short of full alternative-routing guidance.

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