After producing output, validate data quality and completeness:

2. Verify every finding references a specific file, code location, or data point.
3. Verify recommendations are actionable and evidence-based.
4. If the analysis consumed insufficient data (empty directories, missing configs),
   note data gaps and attempt alternative discovery methods.

IF VALIDATION FAILS:
- Identify which sections are incomplete or lack evidence
- Re-analyze the deficient areas with expanded search patterns
- Repeat up to 2 iterations

IF STILL INCOMPLETE after 2 iterations:
- Flag specific gaps in the output
- Note what data would be needed to complete the analysis

- **VVO effectiveness:** [findings]
- **SCADA data quality:** [findings]

### 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.
