update_php_conf_file

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

With no annotations provided, the description carries the entire behavioral burden, and it discloses essentially nothing. It does not say whether the update overwrites content, requires a service restart, has permission requirements, or is destructive. 'Update' only weakly implies mutation.

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 single phrase is brief and front-loaded but is under-specified rather than genuinely concise. It leaves out information the agent needs, so the terseness is a deficit, not efficiency.

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 3-required-parameter mutation tool with no annotations and no output schema, the description is far too thin. Nothing about parameters, behavior, or selection criteria is provided, so an agent cannot use this tool correctly from the definition alone.

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 adds no parameter meaning at all. The three required parameters (id, type, content) are completely undocumented, leaving the agent unable to know what 'id' and 'type' refer to or what format 'content' expects.

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 verb and resource ('Update PHP config file'), so the basic action is identifiable. However, it does not distinguish itself from close siblings like update_php_conf, get_php_conf, and update_php_conf_file, leaving the agent to guess which config-file operation to pick.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives among the many PHP/sibling config tools. The agent gets no signal about when this file-based update is preferred over update_php_conf.

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