Codex install prompt
Install the "use-case" agent skill from https://github.com/ai-driven-dev/framework/tree/main/cli/.claude/skills/use-case. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Creates or modifies application use-cases in src/application/use-cases/. Use when implementing business orchestration for a new feature, extracting a reusable shared use-case, adding a capability sub-use-case, or wiring a PostInstallPipeline delegation. Do NOT use for creating a new CLI command surface — use `command` instead. Do NOT use for I/O translation — use `adapter` instead. Do NOT use for domain type definitions — use `domain-model` instead.

Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.
