Diagnose "that skill doesn't exist" when the skill is installed and working. Use when: (1) the Skill tool refuses a skill name the user just typed as `/name`, (2) a skill named in CLAUDE.md or a docs file is absent from the available-skills listing, (3) `find ~/.claude/plugins -maxdepth 4 -iname "*skill*"` returns nothing for a plugin skill you know is installed, (4) a skill works for the operator but not for the agent, (5) a skill is present in the plugin cache and still unreachable. Three independent mechanisms make a present skill unreachable — `disable-model-invocation: true` frontmatter, plugin-cache directory depth, and project-level `skillOverrides` — and each produces the same symptom. Includes the verification commands for all three and the rule for documenting a skill list so this cannot recur.
