# Og Life > Oil and gas lifecycle management for Beep.OilandGas.LifeCycle. Use when modifying or adding lifecycle process workflows, entity state transitions, PPDM status tables, process/lifecycle services, DTOs, or orchestration across Exploration/Development/Production/Decommissioning phases. Use when this capability is needed. - Skill: `tomevault-io/og-life` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/og-life` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/og-life/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/og-life --- # Og Life ## Overview Enable process/workflow orchestration and entity lifecycle state management for the Beep.OilandGas.LifeCycle solution, including PPDM integration and phase services. ## Quick start 1. Identify the change type: process workflow, entity lifecycle state, integration/orchestration, or database schema. 2. Read `references/lifecycle-overview.md` for service map and dependencies. 3. Apply changes in the correct layer; keep process status and entity status in sync. 4. Update DTOs, integration helpers, and docs if the API surface changes. ## Task playbooks ### Add or modify a process workflow - Update definitions and steps in `Beep.OilandGas.LifeCycle/Services/Processes/ProcessDefinitionInitializer.cs`. - Add or change orchestration methods in `Beep.OilandGas.LifeCycle/Services//Processes/*ProcessService.cs`. - Keep validation rules in `Beep.OilandGas.LifeCycle/Services/Processes/ProcessValidator.cs`. - Extend DTO mappings in `Beep.OilandGas.PPDM39/Core/DTOs/ProcessDTOs.cs` and `Beep.OilandGas.LifeCycle/Services/Processes/ProcessServiceExtensions.cs` when new inputs or outputs appear. - Ensure process tables match changes in `Beep.OilandGas.LifeCycle/Scripts/ProcessWorkflowTables.sql`. ### Add or modify entity lifecycle states - Update state transitions and history in `Beep.OilandGas.LifeCycle/Services/Lifecycle/*LifecycleService.cs`. - Align PPDM status tables and model classes in `Beep.OilandGas.PPDM39/Scripts/Sqlserver/` and `Beep.OilandGas.PPDM.Models/39/`. - Keep state validation consistent with process workflows. ### Integrate process services and orchestration - Register services in API DI (see references). - Use `Beep.OilandGas.LifeCycle/Services/Processes/ProcessIntegrationHelper.cs` to coordinate process execution with state transitions. - Update `FieldOrchestrator` or phase services to use process services where needed. ### Database and schema updates - Process workflow schema: `Beep.OilandGas.LifeCycle/Scripts/ProcessWorkflowTables.sql`. - PPDM entity status schema: `Beep.OilandGas.PPDM39/Scripts/Sqlserver/` plus matching model classes. ## Resources ### references/ - `references/lifecycle-overview.md` - project scope, services, dependencies, migration notes. - `references/processes-guide.md` - workflow architecture, available processes, entity states, setup. - `references/implementation-status.md` - current progress and next steps. - `references/implementation-summary.md` - component inventory and file map. - `references/solution-readme.md` - solution-wide architecture, data patterns, and service conventions. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/the-tech-idea) — claim your Tome and manage your conversions.
