Context Engineering: Why the Best Prompt Engineers Are Abandoning Prompts - Featured image illustration

Last week, I rewrote a system that had taken me two months to perfect. Not because it wasn’t working—it was. The prompts I’d crafted were generating reliable outputs 94% of the time. But after reading about Wikipedia editors’ systematic approach to detecting AI-generated content, I realized something fundamental: we’ve been optimizing the wrong layer.

The Wikipedia community has spent nearly two years cataloging patterns in AI-generated text—not by looking at the prompts that created them, but by analyzing the contextual failures they expose. Their field guide to “Signs of AI writing” reveals that even sophisticated prompts produce content with characteristic tells: excessive emphasis on importance using generic terms like “a pivotal moment,” overuse of present participles to claim vague significance, and that unmistakable tone that “sounds more like the transcript of a TV commercial” than authentic human writing.

This realization changed everything. If the best AI detectors work by identifying contextual deficiencies rather than prompt artifacts, then maybe we’ve been thinking about AI interaction backwards all along.

The Shift Everyone’s Talking About
#

Two weeks ago, Forbes introduced the “collab prompting” technique—a method that transforms AI from a responsive tool into a collaborative partner. The underlying principle? Stop treating each prompt as an isolated question and start building sustained conversational contexts where the AI develops deeper understanding of your actual goals.

The technique works by explicitly requesting that the AI engage as a collaborative partner rather than a myopic responder. As researcher Lance Eliot noted in his November analysis, “the traditional mode of generative AI or large language models is to respond on a very myopic next-turn basis. This robs the human-AI conversation of becoming deep and fully productive.”

But collab prompting is just one piece of a larger transformation. Across the industry, practitioners are realizing that the single prompt—no matter how cleverly engineered—represents a fundamental bottleneck. The real breakthroughs come from designing the entire information ecosystem surrounding that prompt.

What Context Engineering Actually Means
#

Context engineering treats the prompt as one component within a larger system. Instead of asking “How do I write a better prompt?”, context engineers ask “What information does the AI need to succeed at this task?”

This shifts attention to:

Pre-prompt context: What documents, examples, constraints, and background information should the AI have access to before receiving any task? Wikipedia editors found AI content often fails because models lack specific contextual grounding—they generate plausible-sounding but generically worded content because they’re working from general training rather than specific situational knowledge.

Dynamic context loading: As AI agents become more autonomous, they need systems that intelligently load relevant context based on the current task. A prompt alone can’t handle the complexity of multi-step workflows that span different domains and require different expertise.

Context persistence: Traditional prompts are stateless—each interaction starts fresh. Context engineering builds systems that maintain relevant state across interactions, allowing AI to develop genuine understanding of ongoing projects rather than requiring complete recontextualization with every query.

Context verification: How do you confirm the AI actually understood the context provided? The Wikipedia detection patterns show that even with good prompts, AI often generates content that betrays fundamental misunderstandings of the subject matter’s actual context.

Why Wikipedia’s AI Detection Matters
#

The Wikipedia community’s systematic approach to AI detection deserves attention because it reveals the failure modes of prompt-centric thinking. Their guide identifies patterns like:

  • Vague claims of significance: AI-generated content frequently ends clauses with phrases like “emphasizing the significance of” or “reflecting the continued relevance of”—grammatically correct but contextually empty claims that no human writer with actual knowledge would make.

  • Marketing-adjacent language: Because models are trained on internet text that includes substantial marketing content, they produce prose where “landscapes are always scenic, views are always breathtaking, and everything is clean and modern.”

  • Overemphasis on notability: AI text spends excessive time arguing why a subject is important rather than simply conveying substantive information about it—a pattern that emerges from training on content where establishing importance was a key goal.

These aren’t prompt failures—they’re context failures. The AI lacks the situated understanding that would let it write naturally about a topic because it’s been given a task without the contextual grounding that would shape authentic human expertise.

The Collaborative Prompting Foundation
#

The collab prompting technique provides a bridge between traditional prompt engineering and full context engineering. Its template explicitly establishes:

  1. A collaborative relationship where both human and AI work toward shared goals
  2. Permission for the AI to ask clarifying questions rather than immediately generating responses
  3. Expectations for iterative refinement rather than single-shot generation
  4. Recognition that the AI should surface its own uncertainties and limitations

This matters because it creates a context for genuine problem-solving rather than simple task completion. When I implemented collab prompting patterns in my rewritten system, the improvement wasn’t just in output quality—it was in the entire interaction dynamic. The AI began identifying gaps in my requirements before I recognized them myself.

Practical Context Engineering Patterns
#

After three weeks of experimenting with context engineering principles, here’s what’s working:

Layered Context Architecture: Instead of cramming everything into a single prompt, organize context into layers that can be selectively loaded. Base context (always present), domain context (loaded based on task type), task context (specific to current operation), and verification context (examples of correct output for validation).

Context Priming Sequences: Before the main task prompt, send a series of context-establishing messages. Not instructions—information. Documents the AI should understand, examples of similar successful outputs, explicit statements of constraints and preferences. This creates a richer foundation for the actual task.

Feedback Loop Integration: Context engineering isn’t a one-time setup. Build systems that capture what worked and what didn’t, then use that information to refine context for future interactions. The AI’s failures are data about what context was missing.

Human-AI Context Contracts: Explicitly document what context the AI has been given and what it’s expected to infer. This prevents the common failure where AI generates plausible-sounding output that misses crucial contextual requirements that were never actually communicated.

What This Means for Prompt Engineers
#

If you’ve built expertise in prompt engineering, context engineering isn’t a threat—it’s an evolution. The skills transfer directly:

Understanding model behavior, anticipating failure modes, designing for reliability—all of this matters even more when you’re designing context systems rather than individual prompts. What changes is the scope of what you’re designing.

The prompt engineers who thrive will be those who can think systematically about information architecture, not just about linguistic tricks that manipulate model outputs. The Wikipedia detection work shows that surface-level optimization—making text sound human without giving the AI human-like contextual understanding—eventually fails. The patterns are detectable precisely because they’re contextual failures masquerading as successful outputs.

Looking Forward
#

Context engineering is still emerging. The term itself has only gained significant traction in the past month, though practitioners have been developing these approaches for longer. But the direction is clear: as AI systems become more capable and more integrated into complex workflows, the limiting factor is less often model capability and more often the quality of context those models receive.

The Wikipedia AI Cleanup project has been running since 2023, accumulating pattern knowledge that no individual prompt engineer would develop. Their collective intelligence about AI failure modes points toward a future where understanding context requirements is the primary skill, with prompt construction becoming almost incidental—a final step in a much larger design process.

For now, the practical recommendation is simple: stop thinking about your next prompt and start thinking about your entire context system. What does the AI need to know? How will it get that knowledge? How will you verify it understood? Those questions matter more than whether you should use “analyze” or “evaluate” in your instruction text.

The best prompt engineers are already making this shift. The rest of us should catch up.
