Turborepo

This skill explains how Turborepo is used throughout the hr-skills monorepo. It covers workspace orchestration, task execution, caching, package filtering, and development workflows.

Turborepo coordinates tasks across every workspace package while Bun provides the runtime and package management.

Supported tasks

• Explain how Turborepo is used within this repository
• Run workspace tasks from the repository root
• Build workspace packages
• Validate HR skills and repository metadata
• Synchronize generated repository artifacts
• Generate the skill maturity matrix
• Run tests and TypeScript type checking
• Execute filtered workspace tasks
• Recommend efficient development workflows
• Explain Turborepo caching behavior
• Generate CI workflows using Turborepo

Repository usage

This repository uses Turborepo to orchestrate workspace tasks.

Current pipeline tasks include:

• build
• dev
• test
• typecheck
• validate
• sync
• matrix

Repository scripts invoke Turborepo from the workspace root while package-level scripts provide the implementation.

Workspace orchestration

Workspace packages define their own scripts.

Examples include:

• packages/hr-skills-build
• packages/hr-skills-ref

Turborepo automatically coordinates task execution, dependency ordering, and caching across these packages.

Common commands

Run all workspace builds.

bun run build

Run development tasks.

bun run dev

Run repository validation.

bun run validate

Synchronize repository metadata.

bun run sync

Generate the skill maturity matrix.

bun run matrix

Generate the machine-readable skill registry.

bun run registry

Generate usage-informed relevance signals from evaluation golden fixtures.

bun run signals

Search the generated registry by text or domain.

bun run discover "<query>"

Get related-skill recommendations for a skill ID.

bun run recommend <skill-id>

Generate an execution plan for a user intent.

bun run plan "<intent>"

Generate a plan and run it through the workflow runtime.

bun run execute "<intent>"

Run the evaluation framework against eval/datasets.

bun run evaluate

Run every test suite.

bun run test

Run TypeScript type checking.

bun run typecheck

Execute a task directly with Turborepo.

turbo run build

Run a task for a single package.

turbo run build --filter=hr-skills-ref

Run validation for the build package only.

turbo run validate --filter=hr-skills-build

Pipeline overview

Current repository tasks include:

Task	Purpose
build	Build workspace packages
dev	Run development tasks
test	Execute package test suites
typecheck	Run TypeScript type checking
validate	Validate HR skills and repository metadata
sync	Synchronize generated repository artifacts
matrix	Generate docs/engineering/skill-matrix.md skill maturity snapshot
registry	Generate the machine-readable skill registry (registry/skills.json)
signals	Generate usage-informed relevance signals from evaluation golden fixtures
discover	Search the generated registry by text or domain
recommend	Get related-skill recommendations for a skill ID
plan	Generate an execution plan for a user intent
execute	Generate a plan and run it through the workflow runtime
evaluate	Run the evaluation framework against eval/datasets

Examples

Build every workspace package.

bun run build

Validate the repository.

bun run validate

Synchronize generated files.

bun run sync

Generate the skill maturity matrix.

bun run matrix

Build only one package.

turbo run build --filter=hr-skills-ref

Run validation only for the build package.

turbo run validate --filter=hr-skills-build

CI recommendations

A typical validation workflow is:

bun install --frozen-lockfile
bun run typecheck
bun run validate
bun run matrix
bun run test
bun run build

Use Turborepo caching to avoid rebuilding unchanged packages.

Tasks such as sync and matrix intentionally disable caching because they always operate on the latest repository state and write files as a side effect. validate is cacheable (it only depends on ^build) — a repeat run with no source changes replays cached results instead of re-validating.

Tips

• Execute workspace tasks from the repository root.
• Prefer repository scripts (bun run ...) over invoking package scripts directly.
• Use --filter during development to reduce execution time.
• Let Turborepo determine task execution order.
• Keep task outputs deterministic to maximize cache effectiveness.

Common issues

• Running package scripts directly instead of using repository commands.
• Forgetting to use --filter for package-specific development.
• Expecting cached results from tasks that explicitly disable caching.
• Running Turborepo outside the repository root.
• Defining inconsistent task names across workspace packages.

Best practices

• Use repository scripts for everyday development.
• Reserve direct turbo run commands for advanced workflows.
• Keep task names consistent across every workspace package.
• Enable caching only for deterministic tasks.
• Use package filters to shorten development feedback loops.
• Allow Turborepo to manage workspace execution and dependency ordering.
