host-computer-use

Beta desktop control through the connected A0 CLI host. Use for the user's host/local computer screenshots, screen inspection, menus, native app UI, OS-level clicking, scrolling, typing, or checking computer_use_remote status. Use instead of linux-desktop for host/local machine control. Do not use for ordinary browser navigation; host browser requests should use the browser tool.

Quality

Content

100%

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

The body is a lean, highly actionable operating manual: it gives an exact tool contract, a numbered workflow with validation checkpoints, and clear backend-skill escalation paths. It avoids concept re-explanation and verbose padding while remaining complete.

DimensionReasoningScore

Conciseness

The body is dense and operational with no padding and no explanation of concepts Claude already knows — every line is a concrete contract or operating rule, so it earns the 'lean and efficient; every token earns its place' anchor rather than the mostly-efficient level 2.

3 / 3

Actionability

Provides a concrete JSON tool contract, exact argument values, a specific rearm signal (COMPUTER_USE_REARM_REQUIRED), and exact user commands (/computer-use on, chrome://inspect/#remote-debugging), making the guidance copy-paste executable rather than the pseudocode level 2.

3 / 3

Workflow Clarity

The 10-step core loop has explicit validation checkpoints (decide success from the latest screenshot, stop on rearm, switch strategy after two failed attempts), giving clear feedback loops for risky operations rather than the sequence-with-gaps level 2.

3 / 3

Progressive Disclosure

With no bundle files present the skill is organized into well-signaled sections and one-level-deep sibling-skill references (host-computer-use-linux/macos/windows), meeting the scoring note that well-organized skills without external references can score 3 rather than the inline-bulk level 2.

Description

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.

The description is specific, trigger-rich, and explicitly frames both what the skill does and when to use it, while drawing clear boundaries against adjacent skills. It is concise yet complete, with no vague fluff or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'screenshots, screen inspection, menus, native app UI, OS-level clicking, scrolling, typing, or checking computer_use_remote status' — matching the 'lists multiple specific concrete actions' anchor rather than the domain-only level 2.

3 / 3

Completeness

Explicitly answers both what ('Beta desktop control through the connected A0 CLI host') and when ('Use for the user's host/local computer... Use instead of linux-desktop... Do not use for ordinary browser navigation'), satisfying the 'clearly answers both what AND when' anchor and the guideline requiring an explicit 'Use when...' clause.

3 / 3

Trigger Term Quality

Natural user phrasing is well covered ('host computer', 'local computer', 'host browser', 'my screen'), reinforced by the frontmatter triggers list, so it is not the jargon-heavy level 1 or the partial-coverage level 2.

3 / 3

Distinctiveness Conflict Risk

It carves out a clear niche (connected A0 CLI host desktop control) and actively distinguishes from linux-desktop and the browser tool, so it is unlikely to trigger for the wrong skill rather than the overlapping level 2.
