Measure preserved by the flow

Tracking stock levels, managing reservations, handling stock movements, and providing forecasting for e-commerce operations with real-time updates, multi-warehouse support, and low stock alerts.

When the user wants to optimize inventory levels, calculate safety stock, determine reorder points, or minimize inventory costs. Also use when the user mentions "inventory management," "safety stock," "EOQ," "reorder point," "service level," "stockout prevention," "ABC analysis," "inventory turns," or "working capital reduction." For warehouse slotting, see warehouse-slotting-optimization. For multi-echelon systems, see multi-echelon-inventory.

You carry pointers. When you set them down, they become real.

Align architecture and team structure using inverse Conway maneuver

Solve problems by thinking backwards. Use when forward thinking is stuck, you need to identify risks, or find non-obvious solutions. Not for straightforward implementation tasks or simple bug fixes.

When writing, reviewing, or validating user stories. Used by ARCHITECT-AGENT and PRODUCT-OWNER.

Deep bug investigation using consultant agent. Identifies root causes and fix suggestions.

Conduct thorough dependency audits to identify redundant code, unused features, and improper usage patterns. Examines each import to ensure we're leveraging existing capabilities rather than reinventing functionality.

Investigate platform incidents, perform RCA, create incident documentation, and follow alert runbooks in the Kagenti platform

Automatically investigate logs when errors occur, debugging issues, or troubleshooting problems. Check frontend logs (LogViewer) and backend logs (daily log files) for error patterns. Use when user reports bugs, errors appear, or functionality isn't working as expected.

Investigate merkle root mismatch alerts between relayer and validators. Use when alerts mention "merkle root mismatch", "checkpoint root does not match canonical root", or when asked to debug relayer merkle tree issues for a chain. This skill only investigates - use /fix-merkle-root-mismatch to apply fixes.

Use for root cause analysis of bugs or issues. Systematically investigates problems to identify underlying causes.

Investigate stuck messages in relayer queue. Use when alerts mention "queue length > 0", to diagnose why messages are stuck, or to get message IDs for denylisting.

Expert guidance for deep security investigations. Use this when the user asks to "investigate" a case, entity, or incident.

Use when planning or designing features and need to understand current codebase state, find existing patterns, or verify assumptions about what exists - prevents hallucination by grounding plans in reality

Automatically activated when user asks how something works, wants to understand unfamiliar code, needs to explore a new codebase, or asks questions like "where is X implemented?", "how does Y work?", or "explain the Z component"

Investigates HEC-HMS internals through decompiled Java classes. Provides JythonHms API reference, CLI options, version-specific differences (3.x vs 4.x), and guides on-demand decompilation for new discoveries. Use when debugging HMS behavior, discovering undocumented features, understanding version differences, validating automation approaches, or investigating HMS API capabilities. Includes complete JythonHms method reference, Python 2 vs 3 syntax differences, and decompilation tooling. Comp...

Generate weekly PagerDuty incident reports for fan-audio and fusion services with root cause analysis from GCP logs. Outputs a Word document ready to paste into Slack.

Don't dismiss warnings without understanding them - investigate to determine if they indicate bugs, misconfigurations, or are cosmetic, then document findings either way

Analyze feature requests, refactor plans, or technical decisions to determine investment value and provide recommendations. Use when user mentions investigating, analyzing, or asks "should we build this".

Create investigations from security events, detections, or LCQL queries. Performs HOLISTIC investigations - not just process trees, but initial access hunting, org-wide scope assessment, lateral movement detection, and full host context. Builds Investigation Hive records documenting findings with events, detections, entities, and analyst notes. Use for incident investigation, threat hunting, alert triage, or building SOC working reports.

Use when there are 2+ consecutive failures, repeated errors, or the work feels stuck - pauses implementation, switches to root-cause investigation, gathers evidence, and resumes only after a verified plan and options

This skill should be used when the user asks to "investigate code", "analyze implementation", "find patterns", "understand codebase", "debug issue", "find bug", "troubleshoot", or needs evidence-based code analysis and debugging. Provides systematic investigation and debugging methodology.

6-phase investigation workflow for understanding existing systems. Auto-activates for research tasks. Optimized for exploration and understanding, not implementation. Includes parallel agent deployment for efficient deep dives and automatic knowledge capture to prevent repeat investigations.

Scaffolds a structured investigation in scratch/ for empirical research and documentation. Use when the user says "start an investigation" or wants to: trace code paths or data flow ("trace from X to Y", "what touches X", "follow the wiring"), document system architecture comprehensively ("document how the system works", "archeology"), investigate bugs ("figure out why X happens"), explore technical feasibility ("can we do X?"), or explore design options ("explore the API", "gather context", ...
