Metadata

  • Branch: fix/resource-type-namespaced-re-digit-start
  • Commit Message: fix(resource-type): require letter-start for namespace/name in _NAMESPACED_RE
  • Milestone: v3.7.0
  • Parent Epic: #398

Description

The spec requires that namespace and name components in the [[server:]namespace/]name format start with a letter. However, the regex patterns used for custom resource type name validation allow names and namespaces starting with digits.

Code Locations

  • src/cleveragents/domain/models/core/resource_type.py, line 48:

    _NAMESPACED_RE = re.compile(r"^[a-zA-Z0-9][a-zA-Z0-9_-]*/[a-zA-Z0-9][a-zA-Z0-9_-]*$")
    

    Uses [a-zA-Z0-9] as first character class, allowing digit-starting names.

  • src/cleveragents/domain/models/core/_resource_type_validation.py, line 14:

    _NAMESPACED_RE = re.compile(r"^[a-zA-Z0-9_-]+/[a-zA-Z0-9_-]+$")
    

    Uses [a-zA-Z0-9_-]+ which allows digit-starting names.

Note: _BUILTIN_NAME_RE in resource_type.py (line 51) correctly uses [a-zA-Z][a-zA-Z0-9_-]* requiring a letter start. The _NAMESPACED_RE pattern is inconsistent with this and with _SERVER_NS_NAME_RE in project.py.

Expected Behavior

Custom resource type names like 123abc/my-type should be rejected. The _NAMESPACED_RE patterns should require namespace and name to start with a letter, consistent with _BUILTIN_NAME_RE and the _SERVER_NS_NAME_RE pattern in project.py.

Actual Behavior

ResourceTypeSpec(name="123abc/my-type", ...) passes the _NAMESPACED_RE check in resource_type.py because [a-zA-Z0-9] allows digit-starting names.

Note: This is related to but distinct from issue #2936 which covers _TOOL_NAME_PATTERN and _SKILL_NAME_PATTERN in tool.py and skill.py.

Subtasks

  • Fix _NAMESPACED_RE in resource_type.py to use [a-zA-Z] as first character class for both namespace and name components
  • Fix _NAMESPACED_RE in _resource_type_validation.py to use [a-zA-Z] as first character class
  • Add Behave scenarios covering rejection of digit-starting custom resource type names
  • Run nox -e typecheck to confirm no type regressions
  • Run nox (all default sessions), fix any errors

Definition of Done

  • ResourceTypeSpec(name="123abc/my-type", ...) raises ValidationError
  • ResourceTypeSpec(name="local/456-type", ...) raises ValidationError
  • ResourceTypeSpec(name="local/my-type", ...) still succeeds
  • ResourceTypeSpec(name="myorg/custom-db", ...) still succeeds
  • Behave scenarios added covering the new validation
  • All nox stages pass
  • Coverage >= 97%

Starting implementation on branch fix/resource-type-namespaced-re-digit-start.

Plan:

  1. Fix _NAMESPACED_RE in resource_type.py — change [a-zA-Z0-9] to [a-zA-Z] as first character class for both namespace and name components
  2. Fix _NAMESPACED_RE in _resource_type_validation.py — change [a-zA-Z0-9_-]+ to [a-zA-Z][a-zA-Z0-9_-]* for both components
  3. Add Behave scenarios covering rejection of digit-starting custom resource type names
  4. Run nox quality gates
