nlp-pretraining

nlp-pretraining is a skill for Claude Code, Codex from aiming-lab/AutoResearchClaw. It costs 26 tokens per session (321 once invoked), scanned A, original, MIT.

A guide to preparing and fine-tuning language models, which are systems trained to understand and generate text.

In plain words
What is it for?
Use it when writing or reviewing NLP training code, choosing optimizers and learning schedules, applying LoRA or adapters, and evaluating text models.
Why use it?
It helps avoid common training choices that can waste compute or produce unreliable results, and defines suitable evaluation measures.

About the project

AutoResearchClaw is a system that turns a research idea into a scientific paper through autonomous and collaborative AI research workflows. It is for researchers who want agents to investigate questions, run experiments, and produce papers, with optional human guidance. Catalogue skills and agents provide parts of its research workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nlp-pretraining scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

NLP Pretraining/Fine-tuning Best Practice

Fine-tuning recipe:

  • Use pre-trained checkpoints (HuggingFace hub)
  • AdamW optimizer, lr=2e-5 to 5e-5
  • Linear warmup (6% of total steps) + linear decay
  • Batch size: 16-32 (use gradient accumulation for larger effective batch)
  • 3-5 epochs for classification, 1-2 for generation
  • Weight decay: 0.01

Parameter-efficient methods:

  • LoRA: r=8-64, alpha=16-128, apply to q/v projections
  • Prefix tuning: 10-20 prefix tokens
  • Adapters: bottleneck dimension 64-256

Evaluation:

  • Classification: accuracy, F1 (macro for imbalanced)
  • Generation: perplexity, BLEU/ROUGE, human evaluation
  • Use multiple seeds and report mean +/- std
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
