ai-ml-timeseries

ai-ml-timeseries is a skill for Codex from vasilyu1983/AI-Agents-public. It costs 31 tokens per session (3,625 once invoked), scanned A, original, MIT.

A forecasting guide for data recorded in time order, such as daily sales, sensor readings, or demand over future periods.

In plain words
What is it for?
Use it to build and compare local, panel, hierarchical, probabilistic, and time-series foundation-model forecasts with leakage-safe backtesting.
Why use it?
It helps avoid common forecasting mistakes such as using future information during testing or judging predictions as if the data were unrelated rows.

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

ai-ml-timeseries 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ts_evaluator.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Time Series Forecasting - Production Patterns

Scope note: This skill covers forecasting system construction and evaluation. It is not part of the LLM-build or LLM-training stack — route LLM lifecycle, prompting, or provider questions to ai-llm.

July 2026 posture: define a cutoff timestamp before modelling, start with strong baselines, prefer horizon-aware validation over IID thinking, treat known-future covariates explicitly, and verify fast-moving tooling against current official docs before recommending it.

This skill is the implementation guide for forecasting systems:

  • timestamp integrity, frequency checks, and point-in-time feature design
  • local, global/panel, and hierarchical forecasting workflows
  • leakage-safe backtesting, horizon-wise evaluation, and business-loss alignment
  • probabilistic forecasting, calibration, and interval quality
  • time-series foundation models (TSFMs) and zero-shot benchmark patterns
  • forecasting-specific handoff, fallback, and lineage requirements

Use this skill for forecasting depth. Use sibling skills for general data science, generic LLM strategy, or full production operations.

When To Use This Skill

Activate this skill when the user asks for:

  • building or reviewing a forecast model
  • choosing between local, global/panel, hierarchical, or foundation-model approaches
  • creating lag, rolling, calendar, or known-future covariate features
  • designing a rolling-origin backtest or fixing temporal leakage
  • selecting forecasting metrics by horizon, segment, or business cost
  • adding prediction intervals, quantiles, or conformal calibration
  • comparing Chronos-2, Chronos-Bolt, Toto, TimesFM, AutoGluon TimeSeries, MLForecast, skforecast, or classical baselines
  • defining forecast-specific fallback, lineage, and handoff requirements

Scope Boundaries

  • General EDA, tabular modelling, experiment design, or reusable DS workflow -> ai-ml-data-science
  • Deployment architecture, monitoring stack, release gates, incident playbooks -> ai-mlops
  • Generic LLM lifecycle, prompting, or provider selection -> ai-llm
  • RAG and search systems -> ai-rag

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.

ai-ml-timeseries is a skill published in the GitHub repository vasilyu1983/AI-Agents-public (87 stars, last pushed 10d ago), licensed MIT. It adds 31 tokens to every session and 3,625 once invoked, about $0.0002 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.
