lexicon.jargon-undefined

What it flags

Domain-specific terms used without definition. Jargon is contextual: acceptable among specialists, exclusionary otherwise. Like acronyms, jargon creates reading interruptions for the non-specialist; unlike acronyms, these are content words, not uppercase sequences.

At a glance

Detection

1. Maintain multiple jargon lists per domain (tech, legal, medical, admin).
2. User activates the relevant lists via profile.
3. Flag each occurrence of a listed term.

Profile activation

Configuration

In v0.2, the active lists are set by the profile and are not yet user-overridable from lucid-lint.toml. Per-rule TOML overrides — adding custom domain terms, silencing specific entries, or activating a non-default list combination — are tracked as F126 on the roadmap.
