Prompt Engineer

Comprehensive prompt and context engineering. Every non-obvious recommendation must be evidence-scoped.

Canonical Vocabulary

Use these terms exactly throughout all modes:

Term	Definition
system prompt	The top-level instruction block sent before user messages; sets model behavior
context window	The full token budget: system prompt + conversation history + tool results + retrieved docs
context engineering	Designing the entire context window, not just the prompt text — write, select, compress, isolate
template	A reusable prompt structure with variable slots (`{{input}}`, named placeholders, or runtime arguments)
rubric	A scoring framework with dimensions, levels (1-5), and concrete examples per level
few-shot example	An input/output pair included in the prompt to demonstrate desired behavior
chain-of-thought (CoT)	Explicit step-by-step reasoning scaffolding; beneficial for instruction-following models, harmful for reasoning models
model class	Either "instruction-following" or "reasoning" — determines which techniques apply
injection	Untrusted input that manipulates model behavior outside intended boundaries
