Lists multiple specific concrete actions: installing the CLI, enabling desktop app integration, signing in (single or multi-account), reading/injecting/running secrets via op. These are distinct, actionable capabilities.

Clearly answers both what ('Set up and use 1Password CLI') and when ('Use when installing the CLI, enabling desktop app integration, signing in, or reading/injecting/running secrets via op'). The 'Use when...' clause is explicit with specific trigger scenarios.

Includes strong natural keywords users would say: '1Password', 'CLI', 'op', 'secrets', 'signing in', 'desktop app integration', 'injecting'. Covers both the product name and the command-line tool name, which are the most natural trigger terms.

Highly distinctive — 1Password CLI (op) is a very specific tool, and the description names it explicitly along with its unique operations. Unlikely to conflict with other skills unless there's another 1Password-specific skill.

The content is lean and efficient. It doesn't explain what 1Password is or how CLIs work. Every section serves a purpose—workflow steps, tmux requirement, guardrails—with no padding or unnecessary exposition.

Provides fully executable bash commands for the tmux session setup, specific CLI commands for each workflow step (op --version, op signin, op whoami), and concrete guidance on error recovery and multi-account handling.

Clear numbered sequence with explicit validation checkpoints (step 2: verify CLI, step 6: op whoami must succeed before proceeding). Includes error recovery guidance (re-run op signin if not signed in) and a hard gate requiring tmux for all op commands.

References to `references/get-started.md` and `references/cli-examples.md` are clearly signaled and one level deep, which is good structure. However, no bundle files were provided, so we cannot verify these references exist or are useful. The tmux skill cross-reference is also unverifiable. The SKILL.md itself is well-organized but the lack of actual bundle files limits confidence.
