  3. tokuin

    CLI tool – estimates LLM tokens/costs and runs provider-aware load tests for OpenAI, Anthropic, OpenRouter, or custom endpoints.

    Project mention: Show HN: Tokuin – CLI load tester and token estimator for LLM APIs | news.ycombinator.com | 2025-11-08

  4. rllm

    Use multiple LLM backends in a single crate, simple builder-based configuration, and built-in prompt chaining & templating. (by graniet)

  5. skillfile

    One-stop shop for AI skills and agents. Search 110K+ community skills, install and track them declaratively, and deploy across all major AI coding tools (Claude Code, Codex, Cursor, Antigravity and more)

    Project mention: Skillfile, the declarative skill manager, now auto-discovers skills in repos | news.ycombinator.com | 2026-03-19

  6. mdscript

    A template language for composable LLM prompt engineering. Write prompts with variables, loops, conditionals, functions, and imports, then compile to clean Markdown.

    Project mention: Compose your agent prompts once, compile them to every harness | dev.to | 2026-07-06

    If you compose or generate prompts for agents today, whether by hand, with Jinja, or with a Makefile like wshobson's, I'd like to know whether compiling them ahead of time fits your workflow. The repo is github.com/dean0x/mdscript. Issues and stars both help me prioritize.

  7. llm386

    Rust runtime that manages external state for LLM agents — persistent block storage, retrieval, paging into a model-specific token budget, and deterministic prompt assembly.

    Project mention: Reading list (27th April to May 12th) | dev.to | 2026-05-12

    Borrowing from concepts like memory paging that we used to use back in the 32bit CPU architecture era to access larger memory spaces by paging in/out memory, comes a new approach to memory management for your LLMs - link [tool] - ( Added: 2026-05-04 11:16:55 )
