A developer released Perspica, a semantic diff tool for reviewing code, on Hacker News' Show HN. Perspica uses an LLM run to produce semantic groupings of code changes and why they were made, and can …
A developer built TokenCap, a refactoring tool that uses deterministic tree-sitter AST traversal instead of LLM token prediction to perform code transformations such as renaming symbols across a call …
Zerikai Memory, a local code-memory MCP server from developer KikeVen, added Jev, TypeSafe AI's System One judgment model, which scores per-passage relevance, evidence, contradiction and prompt-inject…
A developer built `ivar graph`, a cross-repository code graph for coding agents that keeps a shared SQLite base index of each repo's default branch and per-feature layers holding only changed files, s…
An open-source project called Gortex indexes a codebase into a persistent knowledge graph and exposes it to AI coding agents through MCP, letting agents query for specific functions instead of dumping…
A developer built Sentinel-IR, a deterministic machine-oriented intermediate representation that extracts security-relevant facts from source code — HTTP routes, environment variable reads, file write…
Graphify, an open-source tool launched in April 2026 under dual MIT and Apache-2.0 licenses, converts codebases, documents, and unstructured data into queryable multimodal knowledge graphs to give AI …
Maki v0.5.5, an AI coding agent built by developer tontinton, topped the FrontierHarness Eval benchmark, according to a report published September 19, 2026. Maki's index tool uses tree-sitter to parse…
A developer built Enhanciar, a codebase Q&A tool that forces every generated answer to cite wiki-style page handles resolving to specific repo files and lines, then re-reads each cited source to grade…
Maki, a Rust-based coding agent, parses 15 languages into structural skeletons via tree-sitter, costing 59 tokens per turn while saving 224 tokens on reads, according to the project's documentation. M…
Nanonets released Graft, an MIT-licensed open source CLI tool that builds a queryable code graph for AI coding agents, distributed as the @nanonets/graft package and requiring Node 20 or newer, with v…
A developer built CodeRift, an automated code review platform that analyzes every GitLab merge request through a seven-step pipeline combining TOML-based regex rules, tree-sitter AST analysis, and par…
Graphify, an open-source tool from YC Summer 2026, reduces token usage for AI coding assistants by converting codebases into queryable knowledge graphs, achieving up to 71.5x token reduction in benchm…
Dan Eble released Keel, an open-source harness for coding agents that provides auditable stopping conditions and durable memory, installable via `cargo install keel-harness`. Keel introduces falsifiab…
Celmis, a self-hosted code intelligence tool, builds a deterministic symbol graph of repositories using tree-sitter, enabling cross-repository queries and code review without model involvement. The to…
A developer building a tool to verify claims in bug reports fabricated a security report against one of their own projects, inventing a CVE number that turned out to be a real Linux kernel vulnerabili…
LiuHe, a code-operation toolchain designed for LLM agents, has cut repo-wide symbol indexing from tens of seconds to 98ms. The project, built by developer wulun811, uses a Rust tree-sitter parse daemo…
Graphify-Labs has released graphify, an open-source tool that converts entire codebases into structured knowledge graphs to reduce AI token consumption by up to 71.5x. The tool uses tree-sitter for lo…
A developer built a custom Model Context Protocol (MCP) server using Python to extend AI agents with structured codebase tools. The server, named codebase-memory-mcp, combines SQLite with embeddings a…
Pi, an extension for the earendil-works coding agent, now prompts users for confirmation before executing dangerous shell commands such as `rm -rf`, `terraform destroy`, and destructive Git operations…
