LLM Gross Margin Attribution
Diagnose an LLM gross-margin decline by querying DCE/Crane, comparing a current period against a baseline period, and ranking the margin impact of:
- Model cost / unit-cost change.
- Tenant or workspace mix change.
- Cache hit-rate change.
Do not fabricate numbers. Every metric must come from a live DCE/Crane command, a user-provided real model-cost file, or an explicitly reported missing-data gap.
Runtime dependency rule: use only POSIX sh plus the dce CLI. Cost inputs and
evidence artifacts are JSON. Do not add extra interpreters, JSON parsers,
package installs, or third-party libraries for this skill.
