From skills-for-humanity
Audits a fictional world for internal consistency, texture, economy, and constraint-story alignment. Use when a world feels thin, generic, or like a backdrop.

Worlds fail when they are described rather than inhabited. The difference is texture. A described world tells you what things are — "a dystopian future where technology controls society." An inhabited world shows you what it costs to live there: what people eat, what they fear, what they fight over, what they take for granted, what they lie about. The first is a category. The second is a place.

The second is a place.
The test of a well-built world is not comprehensiveness — it's necessity. Does the world create the story's conflict, or is it merely a backdrop? In a well-integrated world, the story's central problem could only happen in this world, in this configuration. The colony's resource scarcity creates the political structure that creates the protagonist's impossible choice. Remove the world, and the story doesn't exist. In a backdrop world, you could set the same story in contemporary New York without changing anything essential.
The second test: specificity of texture. The world must feel inhabited not through encyclopaedic exposition, but through specific, surprising detail that implies a larger reality. One specific food item, one specific ritual, one specific slang term tells the reader more about the world than three pages of history. The detail does double duty — it characterises the world and implies the systems that produced it.
Step 1: Rules Map the world's governing systems: physical, social, technological, magical, or political. What are the rules that cannot be broken? Are they internally consistent — does the magic system create loopholes the story conveniently exploits? Does the technology appear and disappear based on plot convenience? Rules only function as worldbuilding if they constrain the story.
Framing check: Confirm the specific world being audited before continuing. State what you've identified — the fictional world, its genre/setting, and the story context it operates within — in one sentence, then use AskUserQuestion:
Step 2: History What happened before the story? How does it shape present conditions? The world's history should be visible in the present: in architecture, language, prejudice, ritual, scar tissue. If the history is not visible in the present, it has no function — it's backstory for the author, not texture for the world.
Step 3: Economy How do people survive? How is power acquired and maintained? What do people trade, compete for, hoard, or sacrifice? Economy is the hidden architecture of any world — it determines who has leverage over whom, what choices are available to which people, and what the stakes of any conflict actually are. Worlds without a legible economy feel arbitrary.
Step 4: Texture Specific details that make the world inhabited — not the large-scale facts, but the granular particulars: food, clothing, speech patterns, rituals, insults, jokes, signs, smells. For each world zone (a location, a social class, a faction), identify what specific sensory details are present and what is missing. The test: could these details only exist in this world, or are they generic?
Step 5: Constraint-Story Alignment Does the world's structure create the story's conflict, or is the world irrelevant to the plot? This is the integration test. Map the connection: world rule → social consequence → character situation → story problem. If the chain breaks at any point, the world is decorative rather than load-bearing.
Before proceeding, use the AskUserQuestion tool. State your interpretation of the situation in 1–2 sentences — what is being analyzed and what the core question is — then ask:
Proceed based on their selection. If the user reframes, incorporate the correction before running any analysis.
Rules Inventory: [Physical / social / technological / magical governing rules — internal consistency check — loopholes or conveniences flagged]
History: [Pre-story events + how they're visible in the present / missing historical presence flagged]
Economy: [Survival mechanisms / power acquisition / what is competed over / leverage structures / gaps or arbitrary elements]
Texture: [Present specific details — per zone if relevant / Missing sensory/cultural particulars / World-specific vs. generic details distinguished]
Constraint-Story Alignment: [The chain: world rule → social consequence → character situation → story problem / Where the chain breaks]
Gaps and Inconsistencies: [Internal contradictions / rules violated by plot convenience / areas requiring further development]
