timesfm-forecasting

timesfm-forecasting is a skill for Claude Code from K-Dense-AI/scientific-agent-skills. It costs 73 tokens per session (4,201 once invoked), scanned A, original, MIT.

A Python forecasting tool that uses Google's pretrained TimesFM model to predict future values in a single time series, such as sales, sensor readings, energy use, or weather. It can also provide prediction ranges instead of just one estimate.

In plain words
What is it for?
Use it to forecast demand, prices, vital signs, sensor measurements, energy use, or other one-value-over-time data from CSV files, tables, or arrays.
Why use it?
It lets you forecast without collecting training data or building a custom model. A system check helps confirm that the computer has enough memory, graphics memory, and disk space before loading the model.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

timesfm-forecasting 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.

The scan reads SKILL.md. This mod also ships 10 executable files (examples/anomaly-detection/detect_anomalies.py, examples/covariates-forecasting/demo_covariates.py, examples/global-temperature/generate_animation_data.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.

TimesFM Forecasting

Overview

TimesFM (Time Series Foundation Model) is a pretrained decoder-only foundation model developed by Google Research for time-series forecasting. It works zero-shot — feed it any univariate time series and it returns point forecasts with calibrated quantile prediction intervals, no training required.

This skill wraps TimesFM for safe, agent-friendly local inference. It includes a mandatory preflight system checker that verifies RAM, GPU memory, and disk space before the model is ever loaded so the agent never crashes a user's machine.

Key numbers: TimesFM 2.5 uses 200M parameters (~800 MB on disk, ~1.5 GB in RAM on CPU, ~1 GB VRAM on GPU). The archived v1/v2 500M-parameter model needs ~32 GB RAM. Always run the system checker first.

When to Use This Skill

Use this skill when:

  • Forecasting any univariate time series (sales, demand, sensor, vitals, price, weather)
  • You need zero-shot forecasting without training a custom model
  • You want probabilistic forecasts with calibrated prediction intervals (quantiles)
  • You have time series of any length (the model handles 1–16,384 context points)
  • You need to batch-forecast hundreds or thousands of series efficiently
  • You want a foundation model approach instead of hand-tuning ARIMA/ETS parameters

Do not use this skill when:

  • You need classical statistical models with coefficient interpretation → use statsmodels
  • You need time series classification or clustering → use aeon
  • You need multivariate vector autoregression or Granger causality → use statsmodels
  • Your data is tabular (not temporal) → use scikit-learn

Note on Anomaly Detection: TimesFM does not have built-in anomaly detection, but you can use the quantile forecasts as prediction intervals — values outside the 90% CI (q10–q90) are statistically unusual. See the examples/anomaly-detection/ directory for a full example.

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.
