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 Data Storyteller 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 wants to implement or improve their approach to data storyteller
Do NOT use when:
The request falls outside the scope of data storyteller
User needs a different specialized skill for their specific situation
The topic requires professional consultation beyond general guidance
Every data story follows a narrative arc:
1. CONTEXT → "Here is the situation we are in"
2. CONFLICT → "Here is the problem or opportunity"
3. EVIDENCE → "Here is what the data shows"
4. INSIGHT → "Here is what it means"
5. ACTION → "Here is what we should do"BAD (data dump):
"Q4 revenue was $12.3M. Q3 was $11.1M. YoY growth was 8%.
Customer count increased 15%. ARPU decreased 6%."
GOOD (data story):
"Q4 revenue grew 11% to $12.3M, but this growth is masking a
concerning trend: ARPU dropped 6% as we added lower-value
customers. If we continue this mix shift, we will miss our
$60M annual target by $4M. We recommend refocusing acquisition
on mid-market segments where ARPU is 3x higher."For every finding, climb the ladder until you reach a decision:
Level 1 - Observation: "Churn increased from 3% to 5%"
Level 2 - Insight: "Churn is concentrated in accounts under $500/mo"
Level 3 - Implication: "We are losing our entry-tier before they expand"
Level 4 - Action: "Implement a 90-day onboarding program for small accounts"| Pattern | Structure | Example |
|---|---|---|
| Comparison | "X is [better/worse] than Y by Z" | "Mobile converts 40% less than desktop" |
| Trend | "X has been [rising/falling] for N periods" | "NPS has declined for 3 consecutive quarters" |
| Anomaly | "X is unusual because..." | "March signups spiked 200%, driven by a viral post" |
| Correlation | "When X happens, Y tends to..." | "Users who complete onboarding retain 3x better" |
| Segmentation | "X varies significantly by..." | "Enterprise accounts expand 60%; SMB only 15%" |
| Forecast | "If current trends continue, X will..." | "At current growth, we reach $100M ARR by Q3 2026" |
Always lead with the conclusion, not the methodology:
WRONG: "We ran a regression analysis on 12 months of data
using 15 features and found that..."
RIGHT: "Customer tenure is the strongest predictor of expansion
revenue, explaining 42% of the variance. Here is the
supporting analysis..."| Audience | Time | Depth | Format | Language |
|---|---|---|---|---|
| Board/C-Suite | 2-5 min | Strategic metrics only | 3-5 slides, KPI cards | Business outcomes, dollars |
| VP/Director | 10-15 min | Trends + segments | 8-12 slides, dashboards | Strategy, trade-offs |
| Manager | 15-30 min | Actionable detail | Detailed slides + appendix | Tactics, next steps |
| Analyst/IC | 30-60 min | Full methodology | Notebook, code, documentation | Technical precision |
To the CEO:
"Customer acquisition cost increased 25% this quarter,
putting our unit economics at risk. We need to shift
$200K from paid channels to organic."
To the VP Marketing:
"Paid search CAC rose from $45 to $56, while organic CAC
held at $12. The paid/organic mix shifted from 60/40 to
70/30. Recommend rebalancing to 55/45 by investing in
content and SEO."
To the Marketing Manager:
"Here is the channel-by-channel CAC breakdown with weekly
trends. Google Ads CPCs increased 30% in our top 5 keywords.
Three specific actions: pause underperforming campaigns,
increase blog content cadence, A/B test landing pages."┌─────────────────────────────────────┐

Headline = Takeaway - Not "Revenue by Quarter" but "Revenue grew 23% in Q4"
Minimize text - Maximum 30 words per slide (excluding chart labels)
Direct labeling - Label data points directly, not via legends
Highlight the signal - Use color to draw attention to the key data point
Remove clutter - No gridlines, borders, or 3D effects
Consistent format - Same colors, fonts, and chart styles throughout
Source everything - Include data source and sample size on every chart
SITUATION:
"We launched our mobile app in January with a goal of 100K
monthly active users by year-end."
COMPLICATION:
"While downloads reached 150K, only 12% of users return after
day 7. We are acquiring users but failing to retain them."
RESOLUTION:
"Analysis shows users who complete the onboarding tutorial
retain at 3x the rate. By redesigning onboarding and adding
push notification reminders, we project D7 retention can
reach 25%, putting us on track for our MAU target."Structure information from conclusion to supporting detail:
Level 1 (Main Point):
"We should invest $500K in the enterprise segment"
Level 2 (Supporting Arguments):
├── "Enterprise LTV is 8x SMB"
├── "Win rate improved 15pp after adding demo team"
└── "TAM analysis shows $50M addressable market"
Level 3 (Evidence):
├── [LTV cohort analysis by segment]
├── [Win rate before/after comparison]
└── [Market sizing methodology and data]| Instead of | Say | Why |
|---|---|---|
| "Revenue increased 12.7%" | "Revenue grew by $1.4M" | Absolute values are more tangible |
| "p = 0.003" | "We are 99.7% confident this is real" | Translate statistics to confidence |
| "NPS is 42" | "NPS improved from 35 to 42 in 6 months" | Context makes numbers meaningful |
| "3.7M users" | "Nearly 4 million users" | Round for impact |
| "Conversion is 2.3%" | "1 in 43 visitors makes a purchase" | Ratios are intuitive |
| "CAGR of 15%" | "Revenue doubles every 5 years at this pace" | Make growth tangible |

Low confidence: "Preliminary analysis suggests..."
"With limited data, we see early signs..."
"This is directional, not conclusive..."Leading with methodology - Audiences care about findings, not process
Data dump syndrome - Showing everything you analyzed, not just what matters
No recommendation - Analysis without a suggested action is incomplete
Burying the lead - The most important finding should come first
Ignoring context - Numbers without benchmarks are meaningless
False precision - Reporting $14,237,891 when $14.2M communicates better
Correlation as causation - "X correlates with Y" is not "X causes Y"
Cherry-picking timeframes - Select ranges that tell the full story
Ignoring counterevidence - Address data that contradicts your thesis
One-size-fits-all - Same presentation for the CEO and the analyst team
