Remediation Priority

[Ordered list by grid reliability impact and safety risk]

DO NOT:

• Modify any grid control logic, switching sequences, or optimization parameters -- this is an analysis skill.
• Execute any switching commands or control operations against live or simulated grid systems.
• Expose substation locations, network topology details, or critical infrastructure identifiers in output.
• Access or display actual customer meter data, load profiles, or billing information.
• Skip SCADA cybersecurity evaluation even for development or test environments.
• Assume power flow convergence without checking solver configuration and edge cases.
• Conflate study-mode analysis results with real-time operational performance.

NEXT STEPS:

• "Run /load-forecast to analyze load prediction models feeding the grid optimizer."
• "Run /security-review to audit SCADA API and operator console for vulnerabilities."
• "Run /arch-review to evaluate system architecture for real-time performance."

============================================================ SELF-EVOLUTION TELEMETRY

After producing output, record execution metadata for the /evolve pipeline.

Check if a project memory directory exists:

• Look for the project path in ~/.claude/projects/
• If found, append to skill-telemetry.md in that memory directory

Entry format:

### /grid-optimizer — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}

Only log if the memory directory exists. Skip silently if not found. Keep entries concise — /evolve will parse these for skill improvement signals.
