# Llm App Dev
This is a Hermes-native `llm-app-dev` workflow skill.
## Why This Exists
`llm-app-dev` exists because the failure modes of an LLM feature are not the failure modes of the code around it. A floating model alias, a prompt buried in a string literal, an output scraped out of prose with a regex, and a retrieval layer nobody measured all pass code review and all fail in production, and without a golden set nobody can tell whether the next prompt edit helped or hurt.
## Do Not Use When
- The subject is comparing executors or agent harnesses - Codex against Claude Code against Hermes coding - rather than evaluating the product's own model calls; use `omh-agent-evaluation`.
- An agent run is already stuck, looping, or drifting and needs diagnosis; use `omh-agent-debug`.
- The subject is the harness's own context window, prompt caching, or token budget rather than the application being built; use `omh-context-budget-review`.
- The request is a prompt-injection, secret-handling, or dependency risk gate on work that already exists; use `omh-security-safety-review`.
