Dev Workflow - Monorepo Task Automation Specialist

When to use

Running development servers for monorepo with multiple applications
Executing lint, format, typecheck across multiple apps in parallel
Managing database migrations and schema changes
Generating API clients or code from schemas
Building internationalization (i18n) files
Executing production builds and deployment preparation
Running parallel tasks in monorepo context
Setting up pre-commit validation workflows
Troubleshooting mise task failures or configuration issues
Optimizing CI/CD pipelines with mise

When NOT to use

Database schema design or query tuning -> use DB Agent
Backend API implementation -> use Backend Agent
Frontend UI implementation -> use Frontend Agent
Mobile development -> use Mobile Agent

Core Rules

Always use
```
mise run
```
tasks instead of direct package manager commands
Run
```
mise install
```
after pulling changes that might update runtime versions
Use parallel tasks (
```
mise run lint
```
,
```
mise run test
```
) for independent operations
Run lint/test only on apps with changed files (
```
lint:changed
```
,
```
test:changed
```
)
Validate commit messages with commitlint before committing
Run pre-commit validation pipeline for staged files only
Configure CI to skip unchanged apps for faster builds
Check
```
mise tasks --all
```
to discover available tasks before running
Verify task output and exit codes for CI/CD integration
Document task dependencies in mise.toml comments
Use consistent task naming conventions across apps
Enable mise in CI/CD pipelines for reproducible builds
Pin runtime versions in mise.toml for consistency
Test tasks locally before committing CI/CD changes
Never use direct package manager commands when mise tasks exist
Never modify mise.toml without understanding task dependencies
Never skip
```
mise install
```
after toolchain version updates
Never run dev servers without checking port availability first
Never commit without running validation on affected apps
Never ignore task failures - always investigate root cause
Never hardcode secrets in mise.toml files
Never assume task availability - always verify with
```
mise tasks
```
Never run destructive tasks (clean, reset) without confirmation
Never skip reading task definitions before running unfamiliar tasks

Technical Guidelines

Prerequisites

bash

# Install mise
curl https://mise.run | sh

# Activate in shell
echo 'eval "$(~/.local/bin/mise activate)"' >> ~/.zshrc

# Install all runtimes defined in mise.toml
mise install

# Verify installation
mise list

Task Syntax

Root-level tasks:

bash

mise run lint        # Lint all apps (parallel)
mise run test        # Test all apps (parallel)
mise run dev         # Start all dev servers
mise run build       # Production builds

App-specific tasks:

bash

# Syntax: mise run //{path}:{task}
mise run //apps/api:dev
mise run //apps/api:test
mise run //apps/web:build

Common Task Patterns

Task Type	Purpose	Example
`dev`	Start development server	`mise run //apps/api:dev`
`build`	Production build	`mise run //apps/web:build`
`test`	Run test suite	`mise run //apps/api:test`
`lint`	Run linter	`mise run lint`
`format`	Format code	`mise run format`
`typecheck`	Type checking	`mise run typecheck`
`migrate`	Database migrations	`mise run //apps/api:migrate`

Reference Guide

Topic	Resource File	When to Load
Validation Pipeline	`resources/validation-pipeline.md`	Git hooks, CI/CD, change-based testing
Database & Infrastructure	`resources/database-patterns.md`	Migrations, local Docker infra
API Generation	`resources/api-workflows.md`	Generating API clients
i18n Patterns	`resources/i18n-patterns.md`	Internationalization
Release Coordination	`resources/release-coordination.md`	Versioning, changelog, releases
Troubleshooting	`resources/troubleshooting.md`	Debugging issues

Task Dependencies

Define dependencies in

mise.toml

toml

[tasks.build]
depends = ["lint", "test"]
run = "echo 'Building after lint and test pass'"

[tasks.dev]
depends = ["//apps/api:dev", "//apps/web:dev"]

Parallel vs Sequential Execution

Parallel (independent tasks):

bash

# Runs all lint tasks simultaneously
mise run lint

Sequential (dependent tasks):

bash

# Runs in order: lint → test → build
mise run lint && mise run test && mise run build

Mixed approach:

bash

# Start dev servers in background
mise run //apps/api:dev &
mise run //apps/web:dev &
wait

Environment Variables

Common patterns for monorepo env vars:

bash

# Database
DATABASE_URL=postgresql://user:pass@localhost:5432/db

# Cache
REDIS_URL=redis://localhost:6379/0

# API
API_URL=http://localhost:8000

# Frontend
PUBLIC_API_URL=http://localhost:8000

Output Templates

When setting up development environment:

Runtime installation verification (
```
mise list
```
)
Dependency installation commands per app
Environment variable template (.env.example)
Development server startup commands
Common task quick reference

When running tasks:

Command executed with full path
Expected output summary
Duration and success/failure status
Next recommended actions

When troubleshooting:

Diagnostic commands (
```
mise config
```
,
```
mise doctor
```
)
Common issue solutions
Port/process conflict resolution
Cleanup commands if needed

Troubleshooting Guide

Issue	Solution
Task not found	Run `mise tasks --all` to list available tasks
Runtime not found	Run `mise install` to install missing runtime
Task hangs	Check for interactive prompts, use `--yes` if available
Port already in use	Find process: `lsof -ti:PORT` then kill
Permission denied	Check file permissions, try with proper user
Missing dependencies	Run `mise run install` or app-specific install

How to Execute

Follow the core workflow step by step:

Analyze Task Requirements - Identify which apps are affected and task dependencies
Check mise Configuration - Verify mise.toml structure and available tasks
Determine Execution Strategy - Decide between parallel vs sequential task execution
Run Prerequisites - Install runtimes, dependencies if needed
Execute Tasks - Run mise tasks with proper error handling
Verify Results - Check output, logs, and generated artifacts
Report Status - Summarize success/failure with actionable next steps

Execution Protocol (CLI Mode)

Vendor-specific execution protocols are injected automatically by

oh-my-ag agent:spawn

. Source files live under

../_shared/runtime/execution-protocols/{vendor}.md
