nav_implementations

Navigate to all implementations of an interface or abstract method. Uses language server ground truth for precise, live results.

Instructions

Live 'go to implementations' for an interface/abstract method (language-server ground truth). Same usage pattern as nav_definition: get an exact position first via resolve or map_search + resolve.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "file": "<file>",
      "line": "<line>"
    },
    "name": "nav_implementations"
  }
}

TDQS

A3.8/5.0
Behavior2/5

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

No annotations are provided, so the description carries full burden. It mentions 'language-server ground truth' and 'Live', but fails to disclose behavioral traits like destructive potential, authentication requirements, rate limits, or return format. This is insufficient for a tool with zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with the core purpose and usage pattern. No unnecessary words, making it efficient for an agent to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a navigation tool with no output schema and no annotations, the description is reasonably complete. It covers what the tool does and how to use it. Missing some behavioral details, but for this type of tool it suffices.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all parameters. The description adds minimal extra meaning (only references usage pattern). Baseline 3 is appropriate as the description does not significantly enhance understanding beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool navigates to implementations of an interface or abstract method, using language-server ground truth. It specifies the exact resource and action, and distinguishes itself from siblings like nav_definition by targeting implementations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly provides usage pattern: same as nav_definition, requiring a position from resolve or map_search+resolve. It does not explicitly state when not to use it, but the guidance on prerequisite steps is clear and actionable, earning a 4.

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