The score comes from our model.

• Show HN: How many tokens are you wasting in your context window? · score 7.8

  context-autopsy analyzes local coding-agent transcripts to break down where tokens are spent in the context window, across many agents like Claude Code and Cursor. It distinguishes one-time token additions from 'processed' tokens (multiplied by model calls), highlighting waste from build logs, failed commands, and repeated content. The project provides actionable insights and shareable summaries to help developers optimize their agent usage and costs.

• Show HN: Dbprint – Database Context for Agents · score 7.0

  dbprint profiles live database schemas and data to generate committed plain-text artifacts (DDL, statistics, join graphs, annotations) that coding agents can read offline via an MCP server or CLI, avoiding repeated warehouse queries. It combines multi-engine profiling, agent-assisted annotation of ambiguous values, and CI-checkable data drift detection into a Git-native context layer for AI coding agents.

• Show HN: Code-mode – keep MCP tool results out of Claude Code's context · score 7.0

  Code-mode is a Claude Code plugin that lets the AI write a single JavaScript program to call multiple MCP tools in a sandbox, filtering and joining results before returning only the final answer to the model. This reduces context window usage and token costs, with measured benchmarks showing lower cost per task. It's interesting because it addresses a real pain point in agentic workflows where raw tool outputs flood the context.

• Show HN: Deterministic security scanner for Model Context Protocol · score 7.0

  LIFE FORGE is a deterministic security scanner and behavioral regression testing framework for AI agents using Model Context Protocol (MCP). It builds a simulated digital twin of an agent's tools, uses a MAP-Elites quality-diversity search to find failure scenarios (e.g., unauthorized financial transactions, data leaks), and converts findings into replayable regression tests for CI. The project stands out for judging side effects rather than text and for its native MCP integration.
