Context Retrieval Optimizer

The expensive reality that most AI coding agents retrieve 10-100x more code context than needed, burning through token budgets while actually degrading performance through noise.

App Concept

  • Machine learning system that analyzes your codebase structure, git history, and agent interaction patterns to predict minimal sufficient context
  • Real-time monitoring of agent requests that identifies over-fetching patterns and suggests optimized retrieval strategies
  • Reinforcement learning engine (inspired by SWE-Grep) that experiments with different context selection approaches and learns from success/failure
  • Automated refactoring suggestions for repository structure to make context retrieval more efficient
  • Budget allocation system that dynamically adjusts context depth based on query complexity and available token budget

Core Mechanism

  • Integration layer that sits between your AI agent and codebase, intercepting context retrieval requests
  • Pattern recognition that identifies common query types (bug fix, feature addition, refactor) and applies learned retrieval strategies
  • Multi-turn conversation tracker that maintains context across interactions, avoiding redundant fetches
  • A/B testing framework that continuously experiments with retrieval strategies and measures impact on task success
  • Self-healing context maps (inspired by HN stateful browser agent post) that adapt when codebase structure changes
  • Real-time cost dashboard showing token savings and performance improvements vs baseline retrieval

Monetization Strategy

  • Free tier for individual developers with up to 1K agent interactions/month
  • Team tier ($79/mo per repo) with advanced analytics and custom retrieval strategies
  • Enterprise tier ($499/mo unlimited repos) with dedicated optimization support and SLA
  • Pay-as-you-go option charging $0.10 per 1K optimized retrievals for variable usage patterns
  • Additional revenue from consulting services helping teams restructure codebases for optimal AI interaction

Viral Growth Angle

  • Viral "before/after" screenshots showing 80% cost reduction on identical tasks drives social sharing
  • Integration with popular AI coding tools (Cursor, Continue, Aider) creates natural distribution
  • Weekly "optimization report" email showing cumulative savings creates habit formation
  • Public case studies from well-known open source projects demonstrating impact
  • Developer tool podcasts/newsletters naturally cover cost-saving infrastructure

Existing projects

  • SWE-Grep - Cognition's RL-based retrieval system (on HN today) but proprietary
  • Aider - AI coding assistant with basic context management, not optimized
  • Continue - VS Code AI extension with manual context selection
  • Cursor - AI code editor with proprietary context retrieval
  • Sourcegraph Cody - Code AI with semantic search but no optimization layer
  • Tabnine - Code completion focused, not multi-turn context

Evaluation Criteria

  • Emotional Trigger: Limit risk - developers fear runaway AI costs and want predictable budgets
  • Idea Quality: Rank: 9/10 - Directly inspired by SWE-Grep on HN today; addresses urgent cost pain point
  • Need Category: Foundational Needs - budget for experimentation and access to compute resources
  • Market Size: $800M+ addressable market (every team using AI coding agents needs cost optimization)
  • Build Complexity: High - requires ML pipeline, codebase analysis, and real-time optimization engine
  • Time to MVP: 12-14 weeks with AI coding agents for basic pattern recognition and cost tracking
  • Key Differentiator: Only tool using RL to learn optimal retrieval vs static heuristics; works across all AI coding tools
