project_delete_setting

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

With no annotations, the description carries the full burden and gives partial coverage: it discloses the return value and that deletion targets either a key or a list element by index. It omits error behavior for a missing pointer, whether the file is mutated in place, and any permission/prerequisite context.

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, verb-led and front-loaded, with essentially no waste. The second sentence is mildly redundant given an output schema exists, which keeps it just short of a 5.

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 mutation tool with zero annotations and 0% schema coverage, the description leaves the 'stage' parameter unexplained and says nothing about failure modes. The output schema covers return details, so the missing piece is primarily parameter and error context rather than return format.

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 0%, so the description should compensate. It meaningfully clarifies the 'pointer' parameter (JSON Pointer), ties parameters_file to ProjectParameters.json, and explains key-vs-index targeting, but the 'stage' parameter is never mentioned and no format examples are given for the file path.

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 (Delete) plus resource (a key or list item by index) with the target artifact (ProjectParameters.json) and mechanism (JSON Pointer). An agent can distinguish it from project_get_setting/project_set_setting. It stops short of explicitly naming a sibling to prefer for alternate operations.

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 explicit when-to-use or when-not-to-use guidance. It never routes the agent between this and relatives like project_remove_process or project_set_setting, so the agent must infer the boundary. The 'or list item by index' hint is about mechanics, not selection between tools.

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