Bug Report

Feature Area: Namespacing — Namespace Format Validation
Tested by: UAT tester instance uat-namespacing

What Was Tested

Code analysis of src/cleveragents/domain/models/core/plan.py — the NamespacedName class used as the identity type for actions and plans.

Expected Behavior (from spec)

Per ADR-002 (Namespace System) and the spec's namespace rules, namespace and name components must start with a letter. The parse_namespaced_name() function in project.py uses the regex r"^(?:(?P<server>[a-zA-Z][a-zA-Z0-9_-]*):)?(?P<namespace>[a-zA-Z][a-zA-Z0-9_-]*)/(?P<name>[a-zA-Z][a-zA-Z0-9_-]*)$" which correctly enforces this.

The existing BDD feature file features/plan_namespaced_name_validation.feature also documents this requirement (scenarios tagged @skip referencing issues #2145/#2147):

Scenario: NamespacedName.parse() rejects namespace starting with a digit
  When I parse the namespaced name "123abc/my-action" expecting an error
  Then a ValueError should be raised
  And the error message should contain "must start with a letter"

Actual Behavior

NamespacedName.validate_namespace() in plan.py (line 219–228) only checks that the namespace is alphanumeric with hyphens — it does not enforce that the namespace must start with a letter:

@field_validator("namespace")
@classmethod
def validate_namespace(cls: type[NamespacedName], v: str) -> str:
    """Validate namespace format."""
    if not v:
        return "local"
    # Namespace should be lowercase alphanumeric with hyphens
    if not all(c.isalnum() or c == "-" for c in v):
        raise ValueError("Namespace must be alphanumeric with hyphens only")
    return v.lower()

Similarly, validate_name() (line 230–236) does not enforce that the name must start with a letter:

@field_validator("name")
@classmethod
def validate_name(cls: type[NamespacedName], v: str) -> str:
    """Validate name format (kebab-case recommended)."""
    if not v.replace("-", "").replace("_", "").isalnum():
        raise ValueError("Name must be alphanumeric with hyphens or underscores")
    return v.lower()

This means NamespacedName(namespace="123abc", name="my-action") and NamespacedName.parse("123abc/my-action") succeed silently, creating invalid namespaced names.

The BDD tests that would catch this are tagged @skip (referencing issues #2145/#2147), meaning the validation gap is known but unresolved.

Code Location

  • src/cleveragents/domain/models/core/plan.py, lines 219–236 (validate_namespace, validate_name)
  • features/plan_namespaced_name_validation.feature — skipped scenarios
  • Compare with correct implementation: src/cleveragents/domain/models/core/project.py, lines 32–36 (_SERVER_NS_NAME_RE)

Steps to Reproduce

from cleveragents.domain.models.core.plan import NamespacedName

# Should raise ValueError but doesn't:
nn = NamespacedName(namespace="123abc", name="my-action")
print(nn)  # "123abc/my-action" — accepted incorrectly

nn2 = NamespacedName.parse("123abc/my-action")
print(nn2)  # "123abc/my-action" — accepted incorrectly

Fix

Update validate_namespace() and validate_name() to use a regex that requires the first character to be a letter, matching the pattern already used in project.py:

import re
_NS_PATTERN = re.compile(r"^[a-zA-Z][a-zA-Z0-9_-]*$")

@field_validator("namespace")
@classmethod
def validate_namespace(cls, v: str) -> str:
    if not v:
        return "local"
    if not _NS_PATTERN.match(v):
        raise ValueError("Namespace must start with a letter and contain only alphanumeric characters, hyphens, or underscores")
    return v.lower()

Then un-skip the BDD scenarios in features/plan_namespaced_name_validation.feature.
