# Cyber Defense Team Skill
Orchestrate a 4-agent pipeline that analyzes log files for security threats and produces an incident report.
## Pipeline Architecture
```
[You] → Team Lead (this skill)
│
├─[1]─→ log-ingestor (haiku) → cyber-defense-events.json
│
├─[2]─→ anomaly-detector (sonnet) → cyber-defense-anomalies.json
│ (reads events.json)
├─[3]─→ risk-classifier (sonnet) → cyber-defense-risk.json
│ (reads anomalies.json)
└─[4]─→ threat-reporter (sonnet) → cyber-defense-report.md
(reads all 3 JSON files)
```
Stages 2 and 3 are sequential (each depends on previous output). Stage 4 runs after all data is ready.
## Execution Steps
### Step 1 — Validate Input
Check that the log file exists (or that log content was provided inline). If the path doesn't exist, tell the user immediately — don't proceed.
### Step 2 — Spawn Log Ingestor
Use the Agent tool to spawn the `log-ingestor` agent:
```
Task: Parse the log file at [log_path] and write structured events to cyber-defense-events.json.
Log path: [log_path]
```
Wait for completion. Confirm `cyber-defense-events.json` was created.
### Step 3 — Spawn Anomaly Detector
Use the Agent tool to spawn the `anomaly-detector` agent:
```
Task: Read cyber-defense-events.json and detect anomalies. Write results to cyber-defense-anomalies.json.
```
Wait for completion. If `anomalies_found: 0`, skip to Step 5 (reporter still runs).
### Step 4 — Spawn Risk Classifier
Use the Agent tool to spawn the `risk-classifier` agent:
```
Task: Read cyber-defense-anomalies.json and classify overall risk. Write result to cyber-defense-risk.json.
```
### Step 5 — Spawn Threat Reporter
Use the Agent tool to spawn the `threat-reporter` agent:
```
Task: Read cyber-defense-events.json, cyber-defense-anomalies.json, and cyber-defense-risk.json. Generate a complete incident report and save it to cyber-defense-report.md.
```
### Step 6 — Summarize for User
Read `cyber-defense-risk.json` and present:
```
✅ Analysis complete
Risk Level : HIGH
Score : 74/100
Threats : 2 anomalies detected
Report : cyber-defense-report.md
Primary threat: Brute force attack from 192.168.1.105
Immediate action required: [first recommended_action]
```
## Error Handling
- Agent fails at step 2: Tell user, stop pipeline, show raw error.
- Agent fails at step 3+: Show partial results, note which stage failed.
- Log file not found: "File [path] not found. Provide a valid path or paste log content."
## Cost Estimate
| Stage | Model | Typical tokens |
|-------|-------|----------------|
| log-ingestor | haiku | ~2K |
| anomaly-detector | sonnet | ~3K |
| risk-classifier | sonnet | ~2K |
| threat-reporter | sonnet | ~3K |
| **Total** | | **~10K** |
For large log files (>10K lines), log-ingestor may use up to 20K tokens.
## Example Usage
```
/cyber-defense-team /var/log/nginx/access.log
/cyber-defense-team /tmp/auth.log
```
