 # Changelog
 
+## v1.18.26-dev missing unchecked function argument diagnostic
+
+- Added a focused negative `claro typecheck` fixture for calling a simple function without its declared argument, such as `TEACH greet name` followed by `DO greet`.
+- Improved the static arity check so simple functions without `CHECK TYPE` hints still report a beginner-facing missing-argument diagnostic.
+- Wired the fixture into the typecheck diagnostics validator and `claro validate`.

 ## v1.18.26-dev CI release validation coverage
 
 - Added `tools/validate_ci_workflow.py` to assert that Forgejo/Gitea CI keeps running Claro's current release gates.

 This slice is intentionally small: it covers direct `NEW Class object` plus `SET object.field value` cases in one file. Field declarations are collected even when a learner writes a simple method before a later `HAS` field, so the type checker can still report the field's declared type. Broader object flows, aliases, method return checks, and richer object signatures remain future work.
 
+Simple functions also get an arity check before running. If a learner defines `TEACH greet name` and then writes `DO greet` without the `name` argument, `claro typecheck` reports:

 ## Status
 
 This is currently a static checker feature. It improves `claro typecheck` and validation confidence for `DO` and compatibility `CALL ... WITH` function calls, simple `DO object.method ...` calls where the object was created with `NEW Class name`, and direct assignments to known object fields. Runtime enforcement for every container mutation and richer function/object signatures can be added later after the syntax is classroom-tested.
