AI Prompt Chain / Workflow Designer

How It Works

Describe the complex task and where a single prompt tends to fall short. The builder breaks it into a chain of sequential prompts, each with a clear single job, showing exactly what output from step N feeds into step N+1. You get the finished chain, a diagram of the handoffs, and a review step so errors don't flow silently through to the final output.

What to Provide

Why One Mega-Prompt Fails on Complex Tasks

A single prompt asks the model to extract, structure, write, and quality-check all at once. Each of those is a different cognitive mode, and models silently drop or blend one of them under load - usually the review step, since nothing in the prompt explicitly asks for it. The failure is invisible until you check the output against the source material.

Prompt Chain

Replace [[tokens]] with your details. This is the finished deliverable.

Step 1 - [[Gather/Extract]]

Prompt: "[[Extract the key facts from this input: {{input}}. Output as a bulleted list, one fact per line, no commentary.]]"

Output feeds into: Step 2

Step 2 - [[Structure/Analyze]]

Prompt: "[[Given this list of facts: {{step1_output}}, group them into these categories: {{categories}}. If a fact doesn't fit any category, put it under "Uncategorized" rather than forcing a fit.]]"

Output feeds into: Step 3

Step 3 - [[Draft]]

Prompt: "[[Using this structured information: {{step2_output}}, write {{deliverable}} in {{tone}} following this format: {{format}}.]]"

Output feeds into: Step 4

Step 4 - [[Review/Refine]]

Prompt: "[[Review this draft: {{step3_output}} against these criteria: {{criteria}} and the original source: {{input}}. List any gaps or unsupported claims, then produce a final revised version.]]"

Output: Final deliverable

Worked Examples

Example 1 - Turning Raw Interview Transcripts into a Case Study

Chain: Extract key quotes → Identify the narrative arc (problem/solution/result) → Draft the case study → Fact-check against the original transcript.

Why it needs 4 steps: extraction and narrative structuring are different skills than persuasive writing, and skipping the fact-check step is exactly where case studies drift into exaggeration.

Example 2 - Competitive Research Report

Chain: Extract each competitor's key features from raw research → Structure into a comparison table → Write the analysis/recommendation → Review for unsupported claims.

Handoff detail: the comparison table from step 2 becomes the single source of truth step 3 must cite from - this stops the model inventing a competitor feature that "sounds right" but was never in step 1's extraction.

Example 3 - Multi-Source Meeting Notes to Action Items

Chain: Extract decisions and owners from raw notes → De-duplicate and merge overlapping items → Format as a tracked action list with owner + due date → Flag any item with no clear owner for human follow-up.

Common Mistakes to Avoid

• Chaining when one good prompt would do - adds complexity without added quality for simple tasks; test with a single well-structured prompt first.
• No clear single job per step - steps that overlap in responsibility reintroduce the mega-prompt problem inside a smaller box.
• Losing context between steps - not passing enough of the prior output forward, forcing the model to re-guess information it already extracted.
• No final review step, letting errors from step 2 flow silently into the final output with no chance to catch them.
• Chains too long (6+ steps) where errors compound faster than quality improves - each step is a chance to introduce a new error on top of the last.

Use a chain when a task has genuinely distinct phases - not as a default for everything. If you can't name what makes step 2 different from step 1, you probably don't need two steps.

Choosing Your Handoff Format

The format you pass between steps matters as much as the steps themselves. A vague handoff ("here's what I found") forces the next step to re-interpret loosely structured text; a precise handoff (a bulleted list, a JSON object, a fixed-column table) lets the next prompt operate on exactly what it needs.

Debugging a Broken Chain

When the final output is wrong, don't just re-prompt the last step - inspect each intermediate output first. Most chain failures trace back to step 1 or 2, not the step that produced the visibly bad result.

1. Print/log every intermediate step's output, not just the final one.
2. Check step 1's extraction against the source - if facts are missing here, every downstream step inherits the gap.
3. Check step 2's structuring for silent miscategorization before blaming step 3's writing.
4. Only after 1-3 pass, tune the wording of the failing step itself.
