lightgbm

lightgbm is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 16 tokens per session (235 once invoked), scanned A, original, MIT.

A machine-learning library from Microsoft that builds predictions by combining many decision trees. Its tree-building and histogram methods are designed for large datasets and lower memory use.

In plain words
What is it for?
Use it for classification, prediction, large-scale tabular data, and ranking search or recommendation results.
Why use it?
It provides a way to train models efficiently when datasets are large or when ordinary tree-based training is too slow. It also supports ranking, which orders results for search or recommendation systems.

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

lightgbm 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 9d 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

LightGBM

LightGBM is Microsoft's gradient boosting library. It is often faster and uses less memory than XGBoost due to leaf-wise tree growth.

When to Use

  • Huge Datasets: Optimized for efficiency.
  • Ranking: LGBMRanker is excellent for search/recommendation systems.

Core Concepts

Leaf-wise Growth

Grows the tree by splitting the leaf with max loss delta (creates deeper, unbalanced trees) vs Level-wise (balanced).

Histogram-based

Buckets continuous values into discrete bins for speed.

Best Practices (2025)

Do:

  • Tune num_leaves: The most important parameter for controlling complexity.
  • Use Categorical Features: Pass indexes of categorical columns directly.

Don't:

  • Don't overfit: Leaf-wise growth overfits easily on small data. Limit max_depth.

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.

lightgbm is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 16 tokens to every session and 235 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
