nexus_finalize_exploration

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

With no annotations provided, the description carries full burden but is insufficient. It mentions output files but doesn't disclose critical behavioral traits such as whether this is a read-only or destructive operation, what permissions are required, if it's idempotent, or how errors are handled. The description adds minimal context beyond basic purpose.

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 a single, efficient sentence that front-loads the core action and outputs. It avoids unnecessary words, though it could be slightly more structured by separating purpose from context. Every part earns its place, making it appropriately concise.

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 has an output schema (which should document return values), the description doesn't need to explain outputs. However, with no annotations and 2 parameters (one with an enum), the description is incomplete—it lacks behavioral details and parameter explanations. It's minimally adequate but has clear gaps for a tool that likely performs significant operations.

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 does not. It provides no information about the session_id or mode parameters beyond what the schema shows (e.g., mode has enum values 'terrain_only' and 'full'). The baseline is 3 because the schema covers parameters structurally, but the description adds no semantic meaning to clarify their roles.

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 ('Finalize an exploration session') and specifies the output files (coarse_terrain.json plus optional phantom_gem.json and shimmering_terrain.json). It distinguishes from siblings like nexus_explore_step or nexus_start_exploration by indicating this is a finalization step, though it doesn't explicitly contrast with all related tools.

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 implies usage context by mentioning 'for use with NEXUS JEWELSTORM and WEAVE,' suggesting when the outputs are needed. However, it lacks explicit guidance on when to choose this tool over alternatives like nexus_resume_exploration or nexus_anchor_gems, and doesn't specify prerequisites or exclusions.

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