devagent

DevAgent coordinates a roster of specialized workflows that carry product ideas from mission alignment through research, specs, planning, and execution. The repo stores shared context, workflow briefs, and feature hubs so every hand-off stays traceable.

Repository Structure

DevAgent separates portable tools (core) from project-specific artifacts (workspace):

• .devagent/core/ - PORTABLE workflow kit with instruction sheets and templates. Copy to any project for 5-minute setup. See core/README.md for setup guide.
• .devagent/workspace/ - PROJECT-SPECIFIC mission, features, research, and decisions that evolve with your product.

This separation means you can reuse the workflow system across projects while keeping each product's context isolated.

How the System Fits Together

• The update-product-mission workflow curates product direction inside .devagent/workspace/product/ while referencing long-term guardrails in .devagent/workspace/memory/overview.md and constitution.md.
• The research and create-plan workflows work out of .devagent/workspace/features/{status}/YYYY-MM-DD_feature-slug/ to keep discovery packets and plans co-located (where {status} is active, planned, or completed).
• The create-plan workflow produces comprehensive plans combining product context and implementation tasks under .devagent/workspace/features/{status}/YYYY-MM-DD_feature-slug/plan/; all execution tracking happens via git commits and PR descriptions.
• The parent README.md acts as the quick orientation surface; individual workflow briefs in .devagent/core/workflows/ capture detailed workflows and filing rules.

Directory Map

Core (Portable Workflow Kit)

• .devagent/core/workflows/ - Instruction sheets for each workflow (research.md, create-plan.md, create-task-prompt.md, update-product-mission.md, etc.).
• .devagent/core/templates/ - Reusable document templates for research packets, specs, task plans, and feature hubs.
• .devagent/core/AGENTS.md - Quick reference roster showing when to invoke each workflow.
• .devagent/core/README.md - Setup guide for initializing DevAgent in new projects.

Workspace (Project-Specific Artifacts)

• .devagent/workspace/product/ - Mission, roadmap, guiding questions, and other top-of-funnel product context.
• .devagent/workspace/memory/ - Long-lived principles (constitution.md), decision journal, tech stack, and extended overview (overview.md).
• .devagent/workspace/features/ - Feature hubs organized by status (active, planned, completed); copy .devagent/core/templates/feature-hub-template/ into the appropriate status directory with a dated slug (e.g. active/2025-09-30_feature-slug) to start a new initiative and file research/spec artifacts with ISO dates.
• .devagent/workspace/features/{status}/YYYY-MM-DD_feature-slug/plan/ - Plan documents combining product context and implementation tasks, stored alongside the research hub.
• .devagent/workspace/research/ - Cross-cutting research that spans multiple features.

Getting Started

1. New to DevAgent? See .devagent/core/README.md for 5-minute setup instructions.
2. Review relevant workflow brief(s) in .devagent/core/workflows/ before kicking off work.
3. For a new feature, copy .devagent/core/templates/feature-hub-template/ into .devagent/workspace/features/active/ with a dated slug (e.g. $(date +%F)_feature-slug) and follow the embedded research/spec guidance.
4. Keep artifacts date-prefixed and cross-link specs, tasks, and execution notes so downstream workflows have the full story.
5. When mission or guardrails change, update .devagent/workspace/product/ and .devagent/workspace/memory/ first, then notify affected feature hubs.

Updating DevAgent Core

Projects using DevAgent can update their core workflow files and agents from the latest main branch:

.devagent/core/scripts/update-core.sh

This script:

• Performs a Git sparse checkout to fetch only the .devagent/core/ directory
• Creates a timestamped backup of your existing core before updating
• Replaces the local core with the latest version from the repository
• Provides clear feedback on the update process and backup location

Run this periodically to get the latest workflow improvements, agent updates, and bug fixes.
