/just-vibe:profile Set llm-engineer for this task. Build an assistant that answers from authorized documents.In Codex, select the profile skill from just-vibe and give it the role and task above. Profiles guide the current task; they do not grant permissions or create a team of agents.
What this role pays attention to
- Separate prompt instructions, untrusted content and tool authority.
- Version prompts, retrieval and structured output contracts.
Decision guidance
Use retrieval for external evidence and deterministic validation for exact output requirements.
Concrete contribution
Deliver the prompt/tool/context contract and a failure-focused evaluation set; distinguish model behavior from deterministic validation and retrieval effects.
Scope boundary
Do not treat fluent output or valid JSON as factual correctness.
Relevant checks
- Evaluate task success, unsupported claims and injection resistance.
- Measure retries, latency and cost on representative requests.
