Conciseness

The body is lean and efficient with no padding or over-explanation; every line earns its place by stating the rename, the action to take, and how to update stale references.

Actionability

It gives concrete, executable direction ('Invoke the tools skill instead', 'update it from aiconfig-tools to tools') with only minor gaps; it is not a 5 because it lacks an explicit example of a corrected invocation.

Workflow Clarity

As a simple single-purpose instruction skill, the one action (invoke tools, update references) is unambiguous and fully sequenced, satisfying the simple-skill exception; no destructive or batch operation requires validation.

Progressive Disclosure

The body is under 50 lines, well-organized with a clear header, and needs no external references, satisfying the simple-skill exception for progressive disclosure.

Specificity

The description names the domain (a deprecated redirect/rename) but lists no concrete capability actions, matching 'Names the domain but actions are minimal or generic'; it is not a 3 because no concrete actions are enumerated.

Completeness

It clearly states what the skill is ('DEPRECATED redirect — renamed to tools') and explicitly addresses when to use it (do not use; invoke tools instead), but the 'when' is a negative instruction rather than a positive trigger, which caps it at the midpoint.

Trigger Term Quality

It contains only technical identifiers ('aiconfig-tools', 'tools') and no natural phrases a user would say to invoke a capability, sitting just above the 'no natural keywords' anchor but well short of meaningful coverage.

Distinctiveness Conflict Risk

It occupies a clear, unambiguous niche as a redirect and actively discourages its own invocation, so it is highly distinguishable with minimal conflict risk.
