A helper skill for the Vibe Coding IDE extension that provides code completion suggestions based on active file content and cursor position
Single tool 'assist_vibe_coding' has critical definition gaps. Tool name lacks action verb (should be 'get_code_completion' or 'suggest_code'). Description is present but generic (48 chars, below 50-200 char baseline for LLM optimization). Input schema visible with two parameters, both typed (string, integer) and described, but output schema is NOT documented, LLMs cannot plan downstream actions. No error handling guidance, no parameter constraints (e.g., cursor_line bounds), no indication of what happens on invalid input. Tool appears to be a stub returning hardcoded JavaScript snippet regardless of input, suggesting incomplete implementation. No evidence of idempotency, pagination, or composition with other tools.
Provides code completion suggestions based on active file content and cursor line position
Tool name 'assist_vibe_coding' does not start with action verb. Should be 'get_code_completion', 'suggest_code', or 'generate_completion' to signal intent to LLM.
Output schema not documented. Tool returns dict with 'completion_suggestion' and 'confidence' fields, but LLM has no formal schema to plan downstream actions or validate response structure.
No error handling or recovery guidance. Tool provides no indication of failure modes (e.g., invalid cursor_line, empty file content) or what LLM should do if completion fails.
Input parameters lack constraints. 'cursor_line' integer has no documented bounds (min/max). Description does not specify valid range, format, or behavior for edge cases (line 0, negative, beyond file length).

Tool description is generic (48 chars). Does not explain WHEN to use it vs. alternatives, what confidence score means, or whether suggestions are deterministic. Below 50-200 char LLM-optimization baseline.
