Quality

Content

100%

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

A tight, highly actionable skill body with executable commands, a well-sequenced example workflow that includes a confirmation checkpoint before sending, and clean section organization suited to a single-purpose CLI tool.

DimensionReasoningScore

Conciseness

The body is lean — concrete commands and flags with no explaining of what iMessage is or how messaging libraries work — and every section earns its place, matching the anchor for lean, efficient content that assumes Claude's competence.

3 / 3

Actionability

Provides fully executable, copy-paste-ready commands (e.g. 'imsg send --to "+14155551212" --text "Hello!"') with real flags and a worked jq example, matching the anchor for fully executable code and specific examples.

3 / 3

Workflow Clarity

The Example Workflow lays out a clear find-chat → confirm-with-user → send sequence with an explicit confirmation checkpoint before the irreversible send operation, reinforced by the Safety Rules; matches the anchor for a clear sequence with validation steps.

3 / 3

Progressive Disclosure

No bundle files exist, so the single-file body is appropriately self-contained for this simple CLI skill, organized into clearly labeled sections (When to Use, Commands, Service Options, Safety Rules, Example Workflow) that make navigation easy.

Description

82%

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

A specific, well-targeted description that clearly conveys what the skill does and occupies a distinct niche, but it is missing an explicit 'Use when...' trigger clause, which caps its completeness.

Suggestions

Add an explicit trigger clause, e.g. 'Use when the user asks to send or read iMessage/SMS, check Messages.app chats, or text a contact.'

Include the common natural term 'text/texting' alongside iMessage/SMS to broaden trigger coverage.

DimensionReasoningScore

Specificity

Names a concrete tool (CLI) and multiple specific actions — 'listing chats, history, and sending messages' — matching the anchor for listing multiple specific concrete actions; not level 2 because the actions are concrete and comprehensive rather than partial.

3 / 3

Completeness

Clearly states what the skill does but lacks any explicit 'Use when...' trigger clause, so per the judging guidelines completeness is capped at 2; not level 1 because the 'what' is clearly and specifically stated.

2 / 3

Trigger Term Quality

Includes natural terms users say — 'iMessage', 'SMS', 'chats', 'messages' — giving good coverage, though it omits the common variation 'text/texting' which keeps it from being unimpeachable.

3 / 3

Distinctiveness Conflict Risk

The macOS-specific 'iMessage/SMS CLI' and 'Messages.app' framing carves a clear niche distinct from other messaging channels, making it unlikely to trigger for the wrong skill.
