+    explanation: >
+      This skill's description is present, so it passes the empty-description
+      check, but the text is a placeholder stub ("TODO", "TBD", "FIXME",
+      "placeholder", "no description", "does stuff") rather than a real
+      account of what the skill does. Claude Code always loads the description
+      into context and uses it to decide whether to auto-invoke the skill; a
+      stub gives the model no selection signal and a reviewer no basis for
+      judging the skill's tool grants — functionally the same as no
+      description at all, except CSKILL-070 never sees it.
+    fix: >
+      Replace the placeholder in the SKILL.md `description:` field with a
+      real one-to-two-sentence summary of what the skill does, which tools it
+      uses, and any side effects it may have. For example: "Summarises the
+      current git diff and posts a draft PR description. Uses Bash
+      (read-only git commands) and WebFetch."
