- You need to test what you built (use performing-* skills)
- Task is about configuring existing systems (use configuring-* skills)
- You need to analyze the output (use analyzing-* skills)
- Task is about implementing vendor solutions (use implementing-* skills)
- You don't have infrastructure access
- Task requires compliance validation (use auditing-* skills)
## Red Flags
- Performing actions without explicit written authorization from the asset owner
- Testing against production systems without a defined scope and rules of engagement
- Acting on threat intelligence without validating source reliability
- Sharing classified or sensitive indicators without proper handling procedures
- Alerting threat actors to detection capabilities through visible response actions
## Verification
- All steps executed successfully against a test environment before production use
- Output documented with screenshots or logs demonstrating expected behavior
- Results validated against known-good baselines or reference implementations
- Documentation complete enough for another analyst to reproduce findings
## Process
1. Analyze the task requirements
2. Apply domain expertise
3. Verify output quality
## Anti-Rationalization Table
| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
