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.
