The reason we build Loadout is pretty simple:

1) more than coding, I want more from Codex or Claude Code.

Key details

  • I want them to do some real jobs for me.
  • However, without connections to the real tools they need, they'd stop at planning and talking but not shipping the real result.
  • So, we built Loadout so they can find and use the tools they need without configuring APIs, MCPs or CLIs.

    2) Then, we realized something even worse: it's a nightmare for me to configure an account for every tool the agents need.

  • I have to register accounts, set up payment, and pay for subscriptions for each tool that agents need.

arXiv:2608.05944v1 Announce Type: cross Abstract: We report operational experience full-fine-tuning a 32.76B-parameter dense model (Qwen3-32B) on 16 x NVIDIA B300 (two nodes, FSDP / ZeRO-3) -- among the first published field accounts on this accelerator.

Key details

  • The individual mechanisms we use are established practice; our contribution is the integrated field experience and a set of calibrated measurements on new hardware.
  • Concretely we offer four practitioner artifacts.
  • (1) A B300-calibrated power-draw triage table that distinguishes compute / communication / data-starvation / checkpoint-or-deadlock / idle by board wattage (utilization% reads 100% during an NCCL hang).
  • (2) A set of honest negative results that dispel common optimization folklore at this scale: a controlled A/B in which per-step NFS reading matches a pretokenized local cache (~53k tok/s) because the corpus fits in page cache and the job is compute-bound; a...

Limitations / unknowns

  • (4) A worked failure case -- an epoch-end NCCL deadlock from per-rank token-packing imbalance -- together with a 2.7-second pre-run invariant gate and an external watcher that turn multi-hour silent failures into instant rejections.
  • This deadlock and its remedy correspond to PyTorch's documented Join / equalize-to-minimum practice; we position our instantiation against that prior art and report the GPU-hours the failure cost and the gate saves.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

Key details

  • My agent skills that I use every day to do real engineering - not vibe coding.
  • Developing real applications is hard.
  • Approaches like GSD, BMAD, and Spec-Kit try to help by owning the process.
  • But while doing so, they take away your control and make bugs in the process hard to resolve.

  • This repository is closer to a museum exhibit than a product pitch, a crustacean-run artifact kept alive by clawed gajaes, swept and labeled by agents, and automatically maintained according to the harnesses above.
  • As already described in the project philosophy, this is not meant to be hand-operated like a normal product repo.
  • It is an agent-managed exhibit: the harnesses plan, execute, verify, label, and preserve the artifact while the crabs keep the tank running.

As a result, models trained with standard approaches inherit these omissions, learning to under-report findings themselves.

Key details

  • For example, prior studies show that cardiomegaly may be omitted from ICU chest X-ray reports when the imaging request is focused on monitoring support device placement.
  • As a result, models trained with standard approaches inherit these omissions, learning to under-report findings themselves.
  • We propose PU-DPO, a preference optimization framework to prevent omission noise from corrupting the preference signal.
  • We reformulate the objective under a positive-unlabeled (PU) learning framework, treating absent mentions as unlabeled rather than truly negative.
