Latest finds

Tools, libraries, and articles worth sharing.

  • Modal

    Serverless cloud for AI and data teams — run functions, batch jobs, and GPU inference from Python or JavaScript with no infra to manage.

    Tool2026-07-28
  • Herdr

    Open-source terminal multiplexer built for coding agents — run Claude Code, Codex, OpenCode and more from one terminal on any box, with persistent PTY sessions you can detach and reattach from any device, even a phone over SSH.

    Tool2026-07-27
  • Effect Skill

    Kit Langton's opinionated agent skill for building production TypeScript apps with Effect v4 — workflows, services, layers, schemas, config, schedules, caches, streams, HTTP clients, and tests, with current APIs and production defaults.

    Guideline2026-07-21
  • exe.dev

    Cloud for you and your agents — disposable per-second sandboxes, persistent Linux VPS with SSH/HTTPS, and Devbox cloud dev environments.

    Tool2026-07-16
  • Latitude.sh

    Global AI cloud — deploy bare metal servers and GPU clusters in seconds across 25 locations, with Kubernetes, storage, and managed databases.

    Tool2026-07-16
  • context-doctor

    Claude Code / Codex skill that audits the fixed context a coding agent auto-loads every session — tool/MCP definitions, connectors, plugins, skills, subagents, memory/rules files — and proposes ranked cuts to prune, gate, or route what's loaded but unused.

    Guideline2026-07-06
  • integrations.sh

    A registry of 5,700+ integration specs from Rhys Sullivan — the same builder behind Executor. Every service normalized into MCP, OpenAPI, GraphQL, and CLI form, each surface leading with a grounded, cited credential guide agents can act on.

    Tool2026-07-05
  • Logging Sucks

    Boris Tane's argument that traditional logging is broken for distributed systems and that "wide events" — one comprehensive, high-cardinality structured event per request per service — are the fix. Log what happened to the request, not what your code is doing.

    Article2026-07-04
  • memory-view

    Claude Code / Codex skill that reads a project's auto-memory vault and generates a self-contained HTML explorer to visualize what the agent has remembered — MEMORY.md plus topic files — without editing or managing it.

    Guideline2026-06-27
  • session-report

    Claude Code / Codex skill that generates a self-contained HTML report debugging what is in a session's context window and how every token is spent — context budget, retained thinking, the dumb-zone cutoff, loaded CLAUDE.md and skills, and full history.
