All Skills

Python dataclass best practices: slots, frozen, validation. Trigger when optimizing dataclasses or creating config classes.

Use when tuning predator-prey dynamics, regime detection coefficients, or cooldown mechanisms

Extended hours trading support for pre-market and after-hours sessions via Alpaca

Debugging constant Markov regime features in RL observations - when HMM probabilities show uniform values instead of dynamic regime estimates

SUPERSEDED by persistent-cache-gap-filling (v2.8.0). Cache data during symbol selection for instant repeat runs.

Globus CLI workflow for staging HuBMAP CODEX datasets from remote endpoints to HiPerGator

Batch signal isolation for Phenocycler spleen channels using matched blank pairs and kintsugi.signal

Windows Console Unicode Compatibility

Diagnosing and fixing bimodal matching score distributions in MaxFuse

End-to-end review of agent validation system for live trader readiness. Audits gating thresholds, model health wiring, live feedback loop, notebook consistency.

GPU-accelerated correlation matrix computation with persistent SQLite caching to eliminate bottleneck at correlation calculation during symbol selection

Use when implementing unified position sizing, Kelly criterion, or combining GARCH+Capital+Portfolio risk systems

Integrate Claude agents into training and live trading (v3.0). Trigger when: (1) setting up multi-agent training, (2) adding agent consultation to live trading, (3) configuring orchestrator, (4) understanding agent roles and safety mechanisms.

Mandatory training archive with model gating (APPROVED/REVIEW/DROP). Trigger when: (1) training run completes, (2) need to decide which models to deploy, (3) want historical training reference, (4) need checkpoint recommendations for overfitting.

Training Data Lifecycle Management (v5.4.2)

Convert single-channel TIF directories to pyramidal OME-TIFF with SubIFDs

GPU-safe parallel processing patterns for KINTSUGI to prevent OOM crashes and ensure Jupyter-compatible progress output

Detect processed data produced with old/buggy KINTSUGI code via timestamp forensics

Per-channel skip-existing checks in Snakemake wrapper scripts for resuming interrupted SLURM jobs. Trigger: Snakemake interrupted job, skip existing channels, resume incomplete cycle, sentinel missing but outputs exist, per-channel completeness check, wrapper script resume logic.

Efficient development testing workflow for HPC environments with VS Code tunneling. Trigger: testing code changes on HPC, development workflow with external data directories, VS Code Remote SSH development

Alpaca broker limitations: crypto shorts blocked (broker doesn't support), stock shorts allowed. Trigger when: (1) shorting gate blocks wrong assets, (2) SELL signals blocked, (3) order type confusion.

Integration fixes between backtest engine, FastAPI dashboard, Vue.js frontend, and live trader

MCP (Model Context Protocol) server configuration for Claude Code integration with trading platform. Trigger when setting up MCP servers, fixing alpaca-mcp-server issues, or adding new integrations.

DEPRECATED in v5.6.0 — see joint-multi-tf-v560 skill. Documents the v5.2.0 dual-model approach (train separate 15Min/1Hour models, combine via weighted voting). Still relevant for: (1) loading legacy v5.5.0 dual models, (2) understanding the historical aggregation layer, (3) resampling pattern via origin='start'.

Risk managers should SIZE trades, not BLOCK them. Trigger when: (1) capital manager blocks trades, (2) risk manager rejects orders, (3) trades fail due to 'exceeds limit', (4) components don't work in harmony.

Fix MCP server 'Executable not found' by resolving absolute paths in .mcp.json

Multi-project signal isolation with cascading recipe resolution

Sentinel Validation & Project Promotion

VALIS registration for CODEX: rigid + non-rigid with tuned smoothing. Earlier 'rigid-only' conclusion was caused by a parameter passing bug — all non-rigid tests ran with unsmoothed OpticalFlowWarper.

Pattern for separating repository code from user data and notebooks. Trigger: organizing scientific pipelines, separating code from data

Scale alignment for RNA-protein cross-modal integration - BOTH modalities must be z-scored

GPU-aware PPO training configuration for A100/H100. Trigger when training is slow or GPU utilization is low.

CPI/GDP/retail sales date awareness and VIX regime scaling for calendar features

Cache yfinance sector data permanently to avoid Yahoo Finance rate limits. Trigger when: (1) 401 errors during sector fetching, (2) sector updates take too long, (3) need selective sector refresh.

Patterns for H5AD-backed Shiny apps with Excel fallback, groovy data in .uns, scVI QC validation, Leiden clustering merge, per-donor tissue extraction
