# Domain metaphor nouns Part of [The AI Tells Index](https://feedsquad.com/ai-tells). A tell signals low effort. It does not identify an author. Skilled writers produce every shape listed here, some of them daily, and automated detectors misread those writers for it at rates measured above 60 percent on non-native English prose. Nothing in this index proves that a machine wrote anything. Read an entry as one piece of evidence to weigh against the false-positive notes printed beside it. ## Facts - Id: domain-metaphor-noun - Category: Lexical (lexical) - Subcategory: metaphor-nouns - Also known as: the competitive landscape, the AI landscape, ecosystem, arena, sphere, frontier - Status: Contested. Credible people dispute that this signals anything at all. - Severity: low - Evidence grade: corroborated (named independently by multiple credible secondary sources) - Languages: en - Added: 2026-08-15 - Updated: 2026-08-17 - Page: https://feedsquad.com/ai-tells/domain-metaphor-noun ## Description A spatial or biological metaphor noun standing in where the plain name of the subject would go. The competitive landscape, the developer ecosystem and similar phrases name a shape rather than a set of companies, products or people. The status here is contested, and it should be. Strategy consultants and platform economists coined several of these usages and use them as terms of art with a definition behind them. ## Why it reads as machine-written The metaphor lets a sentence be about a whole field without knowing anything specific about it. That is a useful property when the writer has no particulars, and a wasteful one when they do. ## Detection Type: deterministic (a regular expression, run as written) Scope: sentence ECMAScript regular expression. The build validator compiles it and tests it against this entry's own specimens. ```regex \bthe\s+(?:competitive|AI|digital|marketing|business)\s+landscape\b(?!\s+of\b)|\bthe\s+(?:startup|developer|content|partner|creator)\s+ecosystem\b ``` Flags: gi ## Examples Constructed specimens. Written for this index. Never quoted from anyone's posts. ### Specimen 1 Before, exhibiting the tell: > The competitive landscape for scheduling tools shifted again this quarter, and the developer ecosystem is responding in the ways you would expect it to. Consolidation follows attention, attention has not been in short supply, and where any of it settles is a question most of the people watching closely have already answered for themselves without waiting for the evidence. After, repaired: > Two scheduling tools shipped an agent that drafts and publishes without a human step this quarter. Both charge per seat for it. Nobody has published what happens when the agent posts something wrong. Note: The repair replaces the shape word with the two things that actually moved. ## False positives Who legitimately writes this way. Biologists use ecosystem literally, and have since 1935. Platform economists and strategy researchers use it as a defined term for a set of firms with complementary products, and a paper in that field will use it forty times without a single one being decoration. Competitive landscape has been standard consulting and equity-research vocabulary since long before any language model existed. The pattern only fires on business-modified forms, and it explicitly excludes the opener phrase in the ever-evolving landscape of, which belongs to the scene-setting entry rather than this one. A reviewer should ask whether the writer could have named the members of the ecosystem, and treat the hit as a prompt to ask, never as a finding. ## Model attribution Not attributed. Wikipedia editors observe era drift in this vocabulary, and that periodisation is editor observation rather than measurement. ## Platform notes - wikipedia: The maintained list carries this family with the standing rule that a word being overused does not implicate its synonyms. ## Sources 1.

A retired tell keeps its id and its page. - 2026-08-15, Contested: Contested from the start. Wikipedia lists the family, vale-ai-tells ships rules for it and the LexA per-language data carries the vocabulary, but ecosystem is a defined technical term in two separate fields and the phrase has a documented pre-2022 business register. Listed because the metaphor is worth noticing, graded so that nobody treats a single hit as meaning anything. ## License CC BY 4.0. https://creativecommons.org/licenses/by/4.0/ Attribution: The AI Tells Index, feedsquad.com/ai-tells Reuse the data, including commercially.
