Use this skill when the user needs help creating, testing, validating, or troubleshooting Detection & Response (D&R) rules in LimaCharlie.

Draft a Conventional Commits message from either a short summary of changes or by inspecting the local git diff. Use when the user wants a commit message formatted as type(scope): subject, with optional body and footers for breaking changes or issue references.

Create and script actions for the Drafts app. Use this skill when the user needs help creating custom Drafts actions, understanding action steps, using template tags, scripting with JavaScript, or configuring action workflows for automation and productivity.

Guide for writing Drasi continuous queries using Cypher. Use this when asked to create, modify, or troubleshoot Drasi queries.

Create well-designed posters, layouts, and graphics using DrawBot with automatic enforcement of typography principles from Hochuli, Bringhurst, and Müller-Brockmann. Use when users request posters, layouts, graphics, editorial designs, or mention DrawBot, typography, grid systems, or programmatic design.

Drawer and floating panel system for TMNL. Invoke when implementing drawer stacks, floating panels, drag/resize behaviors, or parallax animations. Provides Rolodex stack, stx-powered state, and container query patterns.

Document patterns for crawling dribl.com fixtures website using playwright-core to extract clubs and fixtures data with Cloudflare protection. Covers extraction (crawling with API interception) and transformation (Zod validation, data merging) phases.

Knowledge and patterns for analyzing project state, detecting plan drift, and creating prioritized reconstruction plans.

Detect documentation drift (docs out of sync with code). Use after changes, periodically, or when something feels wrong. Returns severity-rated findings with specific fixes.

Google Drive management via DriveACSet schema with GF(3) triadic routing. Transforms files/folders into typed Interactions, routes to queue fibers, detects saturation for organized-drive-as-condensed-state.

Preview command effects without making changes. Simulates file writes, git operations, agent spawns, and state changes. All reads execute normally for accurate preview. Use --dry-run flag on any command.

Subagent delegation for data analysis. Dispatches fresh Task agents with output-first verification.

REQUIRED Phase 3 of /ds workflow. Enforces output-first verification at each step.

REQUIRED Phase 2 of /ds workflow. Profiles data and creates analysis task breakdown.

Design system intelligence. Search AntD, Material-UI, Figma, Bootstrap, Tailwind specs. Generate compliant CSS code. Audit for violations. Components, colors, typography, spacing, tokens. Actions: search, generate, audit, review, fix, implement, migrate. Projects: React, Vue, web apps, dashboards, admin panels.

This skill should be used when running Phase 4 of the /ds workflow to review methodology, data quality, and statistical validity. Provides structured review checklists, confidence scoring, and issue identification for data analysis validation.

This skill should be used when the user asks to 'verify analysis results', 'check reproducibility', 'validate data science output', 'confirm completion', or as Phase 5 of the /ds workflow (final). Enforces reproducibility demonstration and user acceptance before completion claims.
