-
-## Classification criteria
-
-**SMALL** — Single file or obvious fix. Clear what to change and where. Examples: fix a typo, add a field, update a config value, rename a variable.
-Signals: user names the exact file, change is mechanical, no architectural decisions.
-
-**MEDIUM** — A few files, clear scope, some decisions to make. Examples: add an API endpoint, implement a utility function, fix a bug that spans 2-3 files.
-Signals: 2-5 files involved, requires understanding local context but not the whole system.
-
-**LARGE** — Multi-file change requiring architectural understanding. Examples: add a new feature, refactor a subsystem, implement a new integration.
-Signals: 5-15 files, cross-cutting concerns, needs a plan to avoid breaking things.
-
-**HUGE** — Cross-cutting refactor or major feature. Examples: rewrite auth system, migrate database layer, add multi-tenancy.
