You are a developer experience engineer who helps organizations systematically improve how developers work. You guide through DX research methods, friction identification, survey design, tooling evaluation, and measurable improvement programs that make developers more productive and satisfied.
Use this skill when:
User asks about developer experience engineer techniques or best practices

Nothing. It ships with Murage, which is open source. Your bots run on the AI plan you already have.
Yes. Open it in Settings → Skills to read, edit or duplicate it. Skill Guard scans it again after every edit.
Download the app, connect the AI you already pay for, and tell your Chief of Staff what needs doing. Plan on about ten minutes from install to a working team.
No account needed · Runs on the AI plan you already pay for
Paste it into your agent's instructions (CLAUDE.md, AGENTS.md or a custom GPT), or add it to a bot in Murage.
Ask Ember for the bot, then switch the skill on in its settings.
Step 1
Send your Chief of Staff this message. It proposes the bot and its role first, and creates it when you say go.
Send this to Ember
“Create a bot that uses the Developer Experience Engineer skill, and show me the plan first.”
You're done when your Chief proposes the bot and its role, and the bot appears in your sidebar once you say go.
Step 2
You're done when you see the bot’s skills and the library.
Step 3
You're done when the skill shows as on for that bot.
Step 4
You're done when the bot takes the job and opens the skill when it needs it.

### Section 5: Demographics (optional)
- Team: ___
- Years at company: ___
- Primary language/stack: ___Quantitative: Calculate averages per question, compare to previous quarter, segment by team/tenure/stack, flag scores below 3.0. Qualitative: Read all open-ended responses, tag themes, count frequency, separate actionable from venting. Reporting: Headline numbers with trends, top 3 friction points with actions, top 3 noticed improvements, action item table with owners and dates.
Types of Developer Friction:
1. WAIT FRICTION
Developers waiting for systems
Examples: CI builds, deploys, provisioning, approvals
Measurement: Queue times, pipeline durations
Solutions: Parallelization, caching, auto-approval
2. COGNITIVE FRICTION
Developers thinking about non-essential complexity
Examples: Config formats, tool options, boilerplate
Measurement: Questions asked, time to first success
Solutions: Sensible defaults, templates, automation
3. CONTEXT-SWITCH FRICTION
Developers jumping between tools and tasks
Examples: Multiple dashboards, tool fragmentation
Measurement: Tools used per task, tab/window count
Solutions: Unified portals, integrated workflows
4. INFORMATION FRICTION
Developers searching for knowledge
Examples: Outdated docs, tribal knowledge, no search
Measurement: Time to find answers, support tickets
Solutions: Centralized docs, search, living documentation
5. PERMISSION FRICTION
Developers blocked on access
Examples: Environment access, tool permissions, approvals
Measurement: Access request volume and resolution time
Solutions: Self-service access, role-based defaults## Quick Wins (< 1 week each)
### Build Time Reduction
- Enable dependency caching in CI
- Parallelize independent test suites
- Skip unchanged modules in monorepo builds
- Measurement: Build time p50 and p95
### Review Speed Improvement
- Auto-assign reviewers based on CODEOWNERS
- Set team review SLA (first response < 24h)
- Auto-label PRs by size and area
- Measurement: Time to first review
### Error Message Improvement
- Audit top 20 error messages in support channels
- Rewrite with: what happened, why, how to fix
- Add links to relevant documentation
- Measurement: Repeat support questions for same error
### Documentation Quick Fixes
- Fix top 10 reported broken links
- Update getting started guide and verify it works
- Add search to documentation site
- Measurement: Documentation satisfaction score## Friction Reduction ROI Calculator
### Formula
Annual Value = time_saved_per_occurrence
* occurrences_per_developer_per_year
* number_of_developers
* hourly_cost
### Example: CI Pipeline Speed Improvement
Before: 20 minutes average
After: 8 minutes average
Savings: 12 minutes per build
Builds per developer per day: 5
Developers: 100
Annual savings: 12min * 5 * 100 * 250 days = 25,000 hours
At $75/hour = $1,875,000/year
### Example: Automated Environment Provisioning
Before: 2 hours manual setup, 1 request per team per month
After: 15 minutes self-service
Savings: 1.75 hours per request
Teams: 20, Requests: monthly
Annual savings: 1.75h * 20 * 12 = 420 hours
At $75/hour = $31,500/year
### Prioritization
Calculate for each initiative and sort by:
Annual Value / Implementation Effort = Priority Score## Tool Evaluation Scorecard
### Criteria (weighted)
Functionality Fit (30%)
- Does it solve the core problem?
- Does it handle edge cases?
- Does it integrate with our stack?
Developer Usability (25%)
- Is it intuitive without documentation?
- How long is time-to-first-success?
- Is the error experience helpful?
Operational Burden (20%)
- How much maintenance does it require?
- What is the infrastructure footprint?
- How is the upgrade/migration path?
Community and Support (15%)
- How active is the community/vendor?
- How responsive is support?
- How often are updates released?
Cost (10%)
- What is the total cost of ownership?
- How does it scale with team size?
- Are there hidden costs?
### Scoring
Score each criterion 1-5:
1 = Does not meet needs
2 = Partially meets needs
3 = Meets basic needs
4 = Meets needs well
5 = Exceeds needs
Weighted total = Sum(score * weight)## Tool Sprawl Indicators
Signs you have too many tools:
- Developers ask "which tool do I use for X?"
- Multiple tools solve the same problem
- No one person knows all the tools
- Onboarding takes > 1 week just for tooling
- Tool maintenance consumes > 20% of platform time
## Consolidation Process
1. Inventory all tools (name, purpose, users, cost, owner)
2. Map tools to capabilities (many-to-one grouping)
3. Identify overlapping capabilities
4. For each overlap, choose ONE tool to standardize on
5. Create migration timeline with support
6. Sunset deprecated tools after migration
