project_code_reindex

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the backend ('sentence-transformers'), notes that it is memory-safe, and implies an index mutation. However, it does not state whether existing vectors are replaced or cleared, whether the operation is expensive or blocking, or what permissions are needed.

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 compact and well-structured: a one-sentence purpose, a clear when-to-use instruction, a useful safety/backend note, and a simple Args section. Every sentence earns its place, and key information is front-loaded.

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 one-parameter tool, this is mostly adequate, but significant gaps remain because there are no annotations and no output schema. The description does not mention return values, the cost or duration of reindexing, whether the operation overwrites the existing index, or how to handle partial failures. These are relevant for a mutating indexing tool.

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?

The only parameter, 'project', is described as 'Project name or path' with concrete examples ('my-app', '~/projects/my-app'). With 0% schema description coverage, this fully compensates for the missing schema-level detail and adds real meaning beyond the parameter's title.

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 states a specific verb ('Reindex'), a specific resource ('a project's source code and docs'), and a clear target ('FalkorDB vectors'). It clearly differentiates this tool from sibling search/query tools by framing it as the index-updating operation.

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 gives a clear usage condition: 'Call this after significant code changes to update the search index.' It does not explicitly name alternatives or exclusions, but the context is clear enough for an agent to know when to select this tool.

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