What it does
Sla Impact Calculator is an agent skill from revfactory/harness-100. Calculation models and business impact matrices for quantitatively assessing incident impact based on SLA/SLO. Use this skill for 'SLA impact', 'SLO violation', 'impact assessment', 'revenue loss estimation', 'error budget', 'availability calculation', 'incident cost assessment', and other tasks quantifying the business impact of incidents. Enhances the impact assessment capabilities of impact-assessor. Note: incident cause analysis and remediation planning are outside the scope of this skill.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud, covering Site reliability engineering. The licence is Apache-2.0.
When your agent uses it
- Impact assessment
- Revenue loss estimation
- Availability calculation
- Incident cost assessment
Example prompts
- “SLA impact”
- “SLO violation”
- “impact assessment”
- “/sla-impact-calculator”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sla Impact Calculator loads about 1.2k tokens when it runs. Until then it costs about 130 tokens; SKILL.md has 161 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SLA Impact Calculator — SLA/SLO-based Impact Assessment Guide
A framework for quantitatively measuring and reporting the business impact of incidents.
SLA/SLO/SLI Framework
SLI (Service Level Indicator): Measurement metric
e.g.: Request success rate = Successful requests / Total requests
SLO (Service Level Objective): Internal target
e.g.: Request success rate >= 99.95% (30-day basis)
SLA (Service Level Agreement): External contract
e.g.: Availability < 99.9% -> 10% credit refund on monthly feeAllowed Downtime by Availability Level
| Availability | Annual Downtime | Monthly | Weekly | Daily |
|---|---|---|---|---|
| 99% | 3d 15h | 7h 18m | 1h 41m | 14m 24s |
| 99.5% | 1d 19h | 3h 39m | 50m 24s | 7m 12s |
| 99.9% | 8h 46m | 43m 50s | 10m 5s | 1m 26s |
| 99.95% | 4h 23m | 21m 55s | 5m 2s | 43s |
| 99.99% | 52m 36s | 4m 23s | 1m | 8.6s |
| 99.999% | 5m 16s | 26s | 6s | 0.86s |
Error Budget Consumption Calculation
Monthly error budget = (1 - SLO) x 30 days x 24 hours x 60 minutes
Example: SLO = 99.95%
Error budget = 0.0005 x 30 x 24 x 60 = 21.6 minutes/month
When a 30-minute incident occurs:
+-- Budget exceeded: 30 min - 21.6 min = 8.4 min over
+-- Consumption rate: 30 / 21.6 = 138.9% (exceeded!)
+-- Remaining budget: -8.4 min (no additional incidents allowed for the rest of the period)Business Impact Matrix
Revenue Loss Estimation
Per-minute revenue loss = Daily average revenue / (24 x 60)
Example: Daily average revenue = $100,000
Per-minute revenue loss = 100,000 / 1,440 = $69.44/min
30-minute incident:
+-- Direct loss: $69.44 x 30 = $2,083
+-- Peak hour adjustment: x 2.5 (if during peak hours)
| -> $5,208
+-- Churn estimate (5% of affected customers churn):
| Affected customers x 5% x Customer Lifetime Value (CLV)
+-- Total estimated loss: Direct + Churn + Recovery costsImpact Severity Levels
| Level | Criteria | Example | Escalation |
|---|---|---|---|
| SEV-1 (Critical) | Core service complete outage | Payments down, entire site down | Immediate -> C-level |
| SEV-2 (Major) | Core feature partial outage | Specific payment method unavailable | Within 30 min -> VP |
| SEV-3 (Minor) | Non-core feature outage | Recommendation system malfunction | Within 1 hour -> Manager |
| SEV-4 (Low) | User experience degradation | Slow page loading | Next business day |
User Impact Scope Calculation
Estimating affected users:
1. Normal traffic for the incident timeframe: DAU x (incident_hours/24)
2. Based on error logs: Unique users receiving 5xx responses
3. Feature usage rate: DAU percentage for the affected feature
Example:
DAU = 100,000
Incident time = 14:00-14:30 (peak)
Time window ratio = 8% (peak hour adjustment)
Affected users = 100,000 x 0.08 x (30/60) = 4,000Financial Impact of SLA Violations
SLA penalty calculation:
Basic structure:
+-- Tier 1: Availability < SLA by 0.1%p -> 10% credit on monthly fee
+-- Tier 2: Availability < SLA by 1.0%p -> 25% credit on monthly fee
+-- Tier 3: Availability < SLA by 5.0%p -> 50% credit on monthly fee
Example: Monthly contract $10,000, SLA 99.9%, actual 99.5%
Shortfall: 0.4%p -> Tier 1
Credit: $10,000 x 10% = $1,000Composite SLA Calculation
Serial system: SLA_total = SLA_A x SLA_B x SLA_C
e.g.: 99.9% x 99.9% x 99.9% = 99.7% (0.3% = 2h 11m/month)
Parallel system: SLA_total = 1 - (1-SLA_A) x (1-SLA_B)
e.g.: 1 - (0.001 x 0.001) = 99.9999%
Real system:
API Gateway(99.99%) -> [App Server(99.95%) || App Server(99.95%)] -> DB(99.99%)
= 99.99% x (1-(0.0005)^2) x 99.99%
= 99.99% x 99.99975% x 99.99%
