10 Mistral Large 4 Prompts Built for Token Efficiency

Mistral Large 4 scores the same as GLM-5.3 on the Artificial Analysis Coding Agent Index while using 47% fewer tokens per task. That efficiency is easy to give back with sloppy prompting. These ten are written to keep it: each one bounds the output, states the stopping condition, and asks the model to refuse rather than guess. Reasoning effort defaults to high and cannot be disabled, so the saving has to come from the prompt rather than the setting.

1
Bound the output before you start
Cost control
Before producing anything, state in one line what the finished output will contain and roughly how long it will be. Wait for me to confirm. Do not begin until I reply.\n\nTask: [TASK]
2
Refuse rather than guess
Accuracy
Answer only from what I have given you. If a detail is missing, stop and name the missing detail instead of inferring it. A short answer that names a gap is worth more to me than a complete answer built on assumptions.\n\nQuestion: [QUESTION]
3
One file at a time
Cost control
We are changing [N] files. Do one file per turn. For each: show only the changed lines with three lines of context either side, never the whole file. Stop after each file and wait.
4
State the stopping condition
Agentic work
Work on [TASK] until [EXPLICIT CONDITION] is true. The moment it is true, stop and say so. Do not continue improving, do not add polish, do not suggest next steps.
5
Plan without prose
Cost control
Give me the plan as a numbered list of actions only. No preamble, no rationale, no summary at the end. If an action needs a decision from me, mark it DECISION and stop there.\n\nGoal: [GOAL]
6
Cite the line, not the file
Accuracy
When you reference existing code, quote the specific lines you are talking about rather than describing where they are. If you cannot quote it, say you could not find it instead of describing it from memory.
7
Terminal work with a budget
Agentic work
Complete [TASK] in no more than [N] commands. Before running anything, list the commands you intend to run. If the task cannot be done within that budget, say so and tell me what the real number is.
8
Multimodal: describe before you conclude
Accuracy
Describe exactly what is in the attached image in plain terms first. Then, in a separate paragraph, answer my question about it. Keep the two apart so I can tell a misreading from a wrong conclusion.\n\nQuestion: [QUESTION]
9
Diff review without the essay
Agentic work
Review the attached diff. Output only defects, one line each, in the form FILE:LINE problem. No summary, no praise, no style opinions unless they cause a bug. If there are no defects, reply with the single word NONE.
10
Long context, narrow answer
Cost control
I am giving you a large document. Answer only this question from it: [QUESTION]. Quote the passages you used, give the answer in under 100 words, and ignore everything else in the document however interesting it is.
