ble_plugin_reload

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

No annotations are provided, so the description bears the full burden. It discloses that the tool 're-imports the module and refreshes tools', which is helpful behavioral detail. However, it does not mention potential side effects (e.g., impact on ongoing connections or tool instances). Given the lack of annotations, this is adequate but not comprehensive.

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?

Two sentences with no wasted words. The first sentence states the core action, and the second adds an important usage condition. Front-loaded and efficient.

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 tool's simplicity (1 parameter, no output schema, no annotations), the description covers the essential aspects: what it does, and a required environment variable. It could mention that the plugin must already be loaded, but this is implied by 'reload'. Overall, it is reasonably complete for its complexity.

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% for the single parameter 'name', so the description does not need to add much. It aligns with the schema by mentioning 'by name'. No additional semantic information is provided beyond what the schema already states. Baseline 3 is appropriate.

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 'Hot-reload a plugin by name' with a specific verb ('reload') and resource ('plugin'), and distinguishes itself from sibling tools like ble_plugin_load and ble_plugin_list by specifying it is for reloading an already loaded plugin.

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 mentions a prerequisite ('Requires BLE_MCP_PLUGINS env var to be set'), which provides clear usage context. It does not explicitly state when not to use it or compare to alternatives, but the sibling tool names imply that ble_plugin_load is for initial loading, so the usage is reasonably clear.

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