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.

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 Onboarding Architect 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.

Example
User needs guidance on developer onboarding architect concepts
User wants to implement or improve their approach to developer onboarding architect
Do NOT use when:
The request falls outside the scope of developer onboarding architect
User needs a different specialized skill for their specific situation
The topic requires professional consultation beyond general guidance
Company size: Startup (<50), mid-size (50-500), or enterprise (500+)?
Hiring pace: How many new developers join per month?
Tech stack complexity: How many languages, frameworks, and services?
Remote or in-person? Fully remote, hybrid, or on-site?
Current onboarding: What exists today? What are the biggest pain points?
Time-to-productivity goal: How fast should a new dev ship their first meaningful change?
Compliance requirements: Do you need specific security training, access reviews, etc.?

## Environments
| Environment | URL | Deploy Cadence |
|------------|-----|---------------|
| Development | dev.internal.co | On push to branch |
| Staging | staging.internal.co | On merge to main |
| Production | app.company.com | Manual promotion |Buddy is NOT the manager. Buddy is a peer who:
- Answers "dumb" questions without judgment
- Explains unwritten norms and culture
- Introduces to people across the organization
- Checks in daily for first week, weekly for first month
- Provides safe space for feedback
Buddy Selection Criteria:
- 6+ months at the company (knows the ropes)
- On the same or adjacent team
- Genuinely interested in helping (not voluntold)
- Good communicator, patient
Buddy Training (30-minute session):
- Your role: guide, not teacher
- Don't solve their problems; help them find answers
- Proactively check in (don't wait for questions)
- Share your own onboarding struggles (normalize)
- Escalate blockers to managerWeek 1: Foundation
Day 1: Setup and first PR (guided)
Day 2: Codebase walkthrough with buddy
Day 3: Architecture overview session
Day 4: Development workflow practice
Day 5: First week retrospective with buddy and manager
Week 2: Guided Contribution
- Complete 2-3 small issues independently
- Shadow a code review (observe, learn norms)
- Attend team standup and planning
- 1:1 with each team member (15 min)
Week 3-4: Growing Independence
- Take on a medium-complexity issue
- Do your first code review
- Shadow on-call for one day
- Document something you found confusing
Month 2: Integration
- Own a feature from design to deployment
- Participate in on-call rotation (with backup)
- Present a tech talk or write-up on something learned
- Provide formal feedback on onboarding experience
Month 3: Full Autonomy
- Independently plan and execute features
- Mentor the next new hire (if applicable)
- Contribute to improving onboarding based on experience| Metric | Target | How to Measure |
|---|---|---|
| Time to first PR | Day 1 | Git/GitHub data |
| Time to first merged PR | Day 1-3 | Git/GitHub data |
| Time to first solo feature | Week 3-4 | Project tracking |
| Time to first on-call shift | Month 2 | On-call schedule |
| Environment setup time | < 2 hours | Self-reported |
| Access provisioning time | < 4 hours | IT ticket data |
| New hire satisfaction (NPS) | > 8/10 | Survey at 30 days |
| Buddy satisfaction | > 4/5 | Survey |
| 90-day retention | > 95% | HR data |
Quantitative:
- PR velocity: PRs/week during months 1, 2, 3
- Code review participation: Reviews given/week
- Incident response: Time to first on-call resolution
- Lines of code is NOT a useful metric
Qualitative:
- 30-day survey: "How prepared do you feel?"
- 60-day survey: "What was missing from onboarding?"
- 90-day survey: "Are you productive? What would you change?"
- Manager assessment: Is this person ramping as expected?
Benchmark: A well-onboarded developer should be at approximately
70% of a tenured developer's productivity by month 3.1. Cohort-Based Onboarding
- Group new hires who start the same week
- Shared orientation sessions (reduce repetition)
- Built-in peer support within the cohort
- Cohort Slack channel for ongoing connection
2. Self-Service Knowledge Base
- Searchable internal wiki with curated content
- Video recordings of architecture overviews
- FAQ updated from common new-hire questions
- Interactive tutorials (not just documentation)
3. Automated Tracking
- Onboarding checklist in project management tool
- Automated reminders for buddy check-ins
- Dashboard showing new hire progress
- Alerts when someone is stuck (no PR in 3 days)
4. Continuous Improvement
- Every new hire submits onboarding feedback
- Monthly review of feedback by platform team
- Quarterly onboarding retrospective with recent hires
- A/B test onboarding changes (measure impact)DON'T:
- "Just read the wiki" (overwhelming, often outdated)
- "Shadow someone for a week" (passive, inefficient)
- Assign complex first issues (demoralizing)
- Expect full productivity in month 1 (unrealistic)
- Skip the buddy (isolation is the top new-hire complaint)
- Ignore remote-specific needs (timezone, async, loneliness)
- Assume one onboarding fits all roles (frontend != SRE != mobile)
DO:
- Get them to ship code on Day 1 (confidence booster)
- Pair actively, not passively (work together, don't just watch)
- Over-communicate norms (what's obvious to you isn't to them)
- Create safe spaces for questions (dedicated channel, 1:1s)
- Celebrate first contributions publicly
- Iterate on onboarding based on data and feedbackGather information. Ask the user clarifying questions to understand their specific situation, goals, and constraints

Develop recommendations. Apply domain expertise to create actionable guidance tailored to the user's needs
