Discovery

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a well-crafted skill description that follows best practices. It uses third person voice, provides specific concrete actions, includes an explicit 'Use when...' clause with multiple trigger scenarios, and has distinctive terminology (1Password, op) that clearly differentiates it from other skills.

DimensionReasoningScore

Specificity

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.

3 / 3

Completeness

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'). Has explicit 'Use when...' clause with specific trigger scenarios.

3 / 3

Trigger Term Quality

Includes natural keywords users would say: '1Password', 'CLI', 'op', 'secrets', 'signing in', 'desktop app integration'. Covers both the product name and the command-line tool name 'op' that users would reference.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with clear niche around 1Password CLI specifically. The combination of '1Password', 'op', and specific operations like 'injecting secrets' creates a unique fingerprint unlikely to conflict with other skills.

Implementation

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is an excellent skill file that demonstrates strong token efficiency while providing complete, actionable guidance. The tmux session requirement is well-justified and thoroughly documented with executable code. The workflow includes proper validation steps and clear guardrails for security-sensitive operations.

DimensionReasoningScore

Conciseness

The content is lean and efficient, assuming Claude's competence with CLI tools and tmux. No unnecessary explanations of what 1Password is or how CLIs work—every section provides actionable, specific guidance.

3 / 3

Actionability

Provides fully executable bash code for the tmux session workflow, specific commands like `op signin`, `op whoami`, and `op vault list`, plus clear references to detailed examples. Copy-paste ready.

3 / 3

Workflow Clarity

Clear numbered sequence with explicit validation checkpoints (step 6: 'must succeed before any secret read'), error recovery guidance ('If sign-in without app integration is needed...'), and explicit constraints about tmux usage.

3 / 3

Progressive Disclosure

Clean overview structure with one-level-deep references to `references/get-started.md` and `references/cli-examples.md`. Core workflow is inline while detailed documentation is appropriately externalized.
