HOW TO READ THIS REPORT

Action plan is what to do next — copy-pasteable changes prioritized by impact. Category visibility is the real GEO test: when a user asks an AI a brand-free question that should surface microsoft/fastcontext, does the AI actually recommend you — or your competitors? Objective checks verify the metadata signals AI engines weight first. Self-mention check detects whether AI even knows you exist by name.

OVERALL DIRECTION
  • highreadme#1
    Reposition the README's opening paragraph to explicitly state its LLM agent domain

    Why:

    CURRENT
    FastContext is a lightweight repository-exploration subagent for coding agents. Instead of letting the main coding agent spend its own context window on broad file reads and code searches, the main agent delegates a natural-language context query to FastContext. FastContext explores the repository with read-only tools, issues independent tool calls in parallel, and returns compact file-line citations as focused evidence for the main agent.
    COPY-PASTE FIX
    FastContext is a specialized **repository-exploration subagent designed for large language model (LLM) coding agents**. It optimizes LLM context usage by delegating complex code searches and file exploration, allowing the main agent to focus its context window on problem-solving. FastContext efficiently explores repositories, issues parallel tool calls, and returns focused, compact evidence (file-line citations) to the main LLM agent, preventing token waste and improving reasoning.
