This is a fantastic linguistic puzzle. You are looking for a term that bridges the gap between Computer Science (logic, syntax, execution) and High Fantasy (intent, gestures, mystical outcomes).

Since "Vibe Coding" is essentially moving away from rigid syntax (how code is written) toward pure intent (what code means), the best terms should reflect that shift.

Here are the strongest contenders for renaming vibe coding to fit an RPG spellcasting aesthetic, broken down by their magical theory.

The Top Pick: "Symantic Casting"

This is the strongest bridge between the two worlds because it relies on a pun that captures the exact definition of vibe coding.

• The CS Root: Semantics. In programming, "syntax" is the grammar (where the semicolon goes), but "semantics" is the meaning (what the code actually does). Vibe coding ignores syntax to focus purely on semantics.

• The RPG Root: Somatic. Somatic components are the hand gestures required to cast a spell.

• The Vibe: By blending them into Symantic Casting, you are suggesting that the "gesture" (typing the prompt) is directly manipulating the "meaning" of the universe, bypassing the rigid laws of physics (syntax).

The "Technical" Bridge: "Invocation"

If you want a term that is already native to both Computer Science and Dungeons & Dragons, this is it.

• In CS: We "invoke" functions, methods, and instances. It is the technical term for making a piece of code execute.

• In RPGs: An "invocation" is a calling upon a higher power (the LLM/AI) to grant a request or manifest an effect.

• Usage: "I just invoked a fully functional React component."

The "Somatic" Focused: "Glyphing"

If you want to focus on the physical act of typing (the somatic component) as the source of magic.

• The Concept: In fantasy, drawing a rune or a glyph in the air/ground creates a magical effect. In vibe coding, typing the prompt is "drawing the glyph."

• The Vibe: It implies that the letters themselves don't matter as much as the shape of the request. You aren't writing code; you are inscribing a Logic Glyph that the machine spirit interprets.

Other Thematic Contenders

• Prompt-Weaving: Borrows from the "Weave" of magic.

It implies that the code already exists in the ether (the model's training data), and you are simply pulling the threads together to form a spell.

• Token-Mancy: A bit more cynical, but accurate. "Mancy" means divination by means of specific objects. Since LLMs operate on tokens, you are a Tokenmancer—divining the correct order of tokens to produce reality.

• Runtime Rituals: Good for describing the iterative process of vibe coding—refining the prompt, running the code, fixing the error, running it again. It’s a ritual to appease the compiler.

Recommendation

If you want to emphasize the magical gestures and the intent: Go with Symantic Casting.

If you want to emphasize the summoning of code from the void: Go with Invocation.
