A sustainability skill gives an AI agent a repeatable way to review software for visible resource-efficiency problems. It focuses on recognizable signals in code, configuration, APIs, and architecture rather than broad product judgments. section 8.5.2
Use the skill as a three-stage review:
- Analyze the resources involved, including CPU, memory, storage, network, package size, and hardware pressure. section 8.5.2
- Audit the project against lean packaging, lean storage, lean communication, efficient execution, and memory efficiency. section 8.5.2
- Report findings with severity, confidence, and assumption flags, while proposing the smallest safe improvement. section 8.5.2
Visible review signals
The skill can identify unused dependencies, oversized payloads, inefficient queries, unbounded caches, and datasets loaded entirely into memory. It should avoid treating every optimization as worthwhile: readability, legal retention obligations, and system context can outweigh small resource savings. section 8.5.2
