connect_devtools

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

With no annotations, the description must carry the behavioral burden. It does disclose the significant project-side effect of launching before connecting, but it omits what happens on failure, whether the connection is persistent, how healthCheck behaves, or whether reconnect is expected to follow. This is a meaningful gap for a connection tool.

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 short with no filler and front-loads the core purpose. However, it is a single terse sentence for a tool with a four-variant target union and two optional behavior-controlling parameters, so brevity comes at the cost of under-specification.

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?

For a complex connection tool with no annotations, no schema descriptions, and four target kinds, the description is incomplete. It does not cover how to invoke the non-project variants, what timeoutMs and healthCheck do, or how this connects to the broader lifecycle managed by sibling tools.

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%, and the description only hints at the project target variant with 'project 固定按 launch → connect 尝试'. It does not explain the target union (project, wsEndpoint, browserUrl, discover), timeoutMs, or healthCheck, so the schema remains the only source and it has no 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 action and resource: connecting to an explicit WeChat Developer Tools target, with a specific behavioral note that project targets follow a launch-then-connect flow. It is reasonably distinct from siblings like reconnect_devtools, though it does not explicitly name or contrast them.

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 gives no explicit guidance on when to use this tool versus reconnect_devtools, disconnect_devtools, or get_connection_status. The phrase 'explicit target' implies a scope, but there are no exclusions, prerequisites, or alternative-tool routing.

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