The score comes from our model.

• Show HN: Hashsync – Deduplicate SSH streams against the receiver's files · score 8.0

  Hashsync is a Rust tool that transparently deduplicates SSH streams by matching data blocks at any offset against an index of files already present on the receiving host, sending references instead of repeated content. It integrates with existing tools like rsync and tar by acting as a drop-in ssh replacement, compressing non-deduplicated data with zstd and verifying all references cryptographically. The approach is novel in its flexibility and tool-agnostic design, enabling large bandwidth savings for backups, file transfers, and synchronization scenarios.

• Show HN: LLM verification pipeline against hallucinations · score 7.8

  VeriQuote is a TypeScript library and CLI that enforces LLM citation verification through a two-stage pipeline: a deterministic fuzzy matcher confirms quotes exist in sources, and an LLM judge assesses whether quotes support claims. It addresses the critical problem of hallucinated citations in retrieval-augmented generation, with extensive benchmarks showing complementary blind spots between the two checks.

• Show HN: PR-witness – run the base branch's tests against the PR's code · score 7.5

  pr-witness runs the base branch's tests against a PR's code to detect hidden regressions and test manipulations that CI misses. It introduces multiple signals like cross-run comparison, expectation changes, and coverage replacement to flag suspicious test edits. The project is well-documented with honest evaluation, a GitHub Action, and Claude Code plugin.

• Show HN: Guard hooks for Claude Code, tested against a public corpus · score 7.3

  A collection of guard hooks and skills for Claude Code that block destructive shell commands, prevent secret leakage, and automate common repository chores like commit messages and PR descriptions. It's notable for its rigorous testing methodology, including a public tamper-case corpus, unit tests, and versioned eval transcripts that demonstrate reliability and effectiveness.
