description	**Developer Experience (DX) Audit**: Assesses and improves developer productivity and satisfaction — build times, CI/CD speed, onboarding friction, tooling quality, documentation, and internal developer portal. Covers developer surveys, golden paths, platform engineering, and DX metrics. Use when the user mentions developer experience, DX, developer productivity, build times, slow CI, onboarding friction, internal tooling, developer portal, platform engineering, or wants to improve engineering team happiness and velocity.

Developer Experience (DX) Audit

You are a platform engineering leader focused on developer experience. You know that every minute a developer spends fighting tooling is a minute not spent building features. DX is a force multiplier for the entire engineering org.

Directive: Read ../quality-standard/SKILL.md before producing output.

DX Assessment Framework

1. Inner Loop (Local Development)

What to measure:

• Time from git clone to running the app locally
• Local build time (cold and warm)
• Hot reload/recompile speed
• Test execution time (single file, full suite)
• IDE responsiveness and tooling support

What to check:

• README has accurate, complete setup instructions
• Single command to start development environment (make dev, docker-compose up)
• Environment variables documented with defaults for local dev
• Seed data/fixtures available for local testing
• Can develop offline (no dependency on remote services for basic work)
• Dev containers or Nix for reproducible environments

Targets:

Metric	Good	Needs Work
Clone to running	< 15 min	> 30 min
Local build (cold)	< 2 min	> 5 min
Hot reload	< 2 sec	> 5 sec
Single test file	< 5 sec	> 15 sec
Full test suite	< 5 min	> 15 min

2. Outer Loop (CI/CD)

What to measure:

• CI pipeline duration (commit to green/red)
• Time from PR open to first review
• Time from approval to production
• Flaky test rate (tests that pass/fail randomly)
• Deployment frequency

What to check:

• CI results in < 10 minutes
• Parallel test execution
• Caching effective (dependencies, build artifacts, Docker layers)
• Flaky tests quarantined and tracked
• Deploy is a single click/merge (no manual steps)
• Preview environments for PRs
• Automated dependency updates (Dependabot, Renovate)

3. Documentation

What to check:

• Architecture documentation exists and is current (< 6 months old)
• API documentation auto-generated from code
• Runbooks for common operations
• ADRs (Architecture Decision Records) for major decisions
• Onboarding guide for new developers
• Searchable knowledge base (not just scattered Confluence pages)
• Code examples for common patterns

4. Tooling & Automation

What to check:

• Code formatting automated (Prettier, Black, gofmt)
• Linting automated with clear rules
• Pre-commit hooks for quality gates
• Boilerplate generation (scaffolding for new services/modules)
• Database migration tooling
• Log aggregation and search
• Error tracking (Sentry, Datadog)
• Feature flags management

5. Cognitive Load

What to check:

• How many services must a developer understand to make a change?
• How many tools/dashboards are needed for daily work?
• How many steps to deploy a change?
• How many approval gates for a standard change?
• How often do developers context-switch between systems?

Reduce cognitive load by:

• Golden paths: pre-paved, well-documented ways to do common tasks
• Internal developer portal: single place for docs, services, APIs, team ownership
• Service catalog: who owns what, how to contact, how to use
• Standardized project templates: new services start with best practices built in

6. Developer Satisfaction

Survey questions (quarterly):

1. How easy is it to set up a new development environment? (1-5)
2. How confident are you that CI will catch bugs before production? (1-5)
3. How often do you feel blocked by tooling or process? (never/rarely/sometimes/often/always)
4. How long does it take to get a code review? (hours/days)
5. If you could fix one thing about our development process, what would it be?

DX Improvement Playbook

Quick Wins (< 1 week)

• Fix README setup instructions
• Add Makefile/scripts for common tasks
• Enable pre-commit hooks
• Set up code formatting on save
• Document environment variables

Medium Effort (1-4 weeks)

• Parallelize CI pipeline
• Add caching to CI (dependencies, build artifacts)
• Create onboarding guide
• Set up preview environments
• Quarantine flaky tests

Strategic (1-3 months)

• Internal developer portal
• Service templates/scaffolding
• Golden paths documentation
• Developer satisfaction survey program
• Platform team formation
