host-computer-use-macos

Backend-specific macOS guidance for `computer_use_remote`. Load after `status` or `start_session` reports backend_family/backend_id `macos` or Accessibility-tree features. Covers AX structural targeting, macOS window actions, and screenshot verification.

Quality

Content

96%Weight 40%Scale 1-5

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

An exemplary single-file skill: fully executable JSON examples, feature-conditional decision trees, and explicit screenshot-verification feedback loops on every state-changing action. The only structural note is that everything lives in SKILL.md with no reference files, which is acceptable at this size but leaves navigation flat.

DimensionReasoningScore

Conciseness

The body is entirely directive backend-specific constraints (feature flags, dispatch semantics, error codes) with zero explanations of concepts Claude already knows; nothing is trimmable without losing information.

5 / 5

Actionability

Three complete copy-paste-ready JSON tool invocations (`element_action`, `ax_snapshot`, `ax_action`), an enumerated operations list (`press`/`focus`/`set_value`), concrete targeting decision rules, and exact error-code remediation ("run `/computer-use on` in the A0 Launcher chat").

5 / 5

Workflow Clarity

Sequences are explicit with feedback loops: "If an action reports ambiguity, take a fresh snapshot and narrow the target", "After any hide or minimize shortcut, inspect the fresh screenshot", and "stop immediately and ask the user" on rearm errors — matching the validate-then-retry checkpoint pattern.

5 / 5

Progressive Disclosure

Sections (AX Targeting, Window Actions, Permissions) are clear and everything in the single file belongs there, but the ~100-line body has no reference split, so it matches the good-structure anchor rather than the reference-organized top anchor.

Description

87%Weight 40%Scale 1-5

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 tightly scoped, third-person description that names its parent tool, its platform niche, its three capability areas, and an explicit backend-report-based load condition. It is nearly ideal; the only gaps are a few missing natural synonyms (e.g., "Mac") and unmentioned capabilities like permission handling.

DimensionReasoningScore

Specificity

"Covers AX structural targeting, macOS window actions, and screenshot verification" lists several concrete capabilities, matching the several-specific-actions anchor; not 5 because coverage gaps exist (permissions handling and dispatch semantics are unmentioned in the description).

4 / 5

Completeness

"Backend-specific macOS guidance for `computer_use_remote`" answers what, and "Load after `status` or `start_session` reports backend_family/backend_id `macos` or Accessibility-tree features" answers when with concrete trigger conditions.

5 / 5

Trigger Term Quality

Terms "macOS", "computer_use_remote", "Accessibility-tree", "AX", "window actions", and "screenshot" give good natural keyword coverage; not 5 because common synonyms like "Mac" or "Apple" are absent.

4 / 5

Distinctiveness Conflict Risk

The description carves a clear niche (the macOS backend of one specific tool) with an explicit machine-checked load condition, so overlap with generic computer-use or other-platform skills is minimal.
