Project preset

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

Annotations mark it non-readOnly, idempotent, non-destructive, closed-world. The description adds valuable detail beyond that: it writes a file (.grok-mcp.json) only when a preset is supplied, otherwise it's a read. This dual mode is not derivable from the idempotent/non-destructive hints. Minor gap: doesn't say which permissions or whether it errors on missing file.

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?

Three tight sentences, front-loaded with the operation and value domain. No wasted words, but the telegraphic style ('it reports/writes') is slightly terse for an agent needing precision.

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, 3 params with 0% schema coverage, so the description carries responsibility. It covers the core read/write semantics and trigger condition but omits what 'reports' returns and what 'project_root'/'note' do, leaving gaps an agent might need. Just adequate.

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%, so the description must compensate, but it only names the enum values (off/cheap/standard/max) implicitly via 'preset' and never explains 'project_root' or 'note'. Baseline of 3 is appropriate since the enum is the key semantic and the description implies its role, but the two undocumented non-enum params remain unexplained.

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 dual-purpose operation (read or set the project's Grok preset) named after the config file it manages. The name 'grok_agent_project' is generic, but the description clarifies the resource is the '.grok-mcp.json' preset. Distinguishable from siblings like grok_agent_status/economy, though not explicitly compared.

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?

Explicit triggering condition: 'Use first when a job tool returns PROJECT_NOT_ENABLED,' which is strong actionable guidance. Also clarifies the read-vs-write behavior: 'Without preset it reports; with preset it writes.' No explicit exclusions of alternatives named, but the context is clear.

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