host-computer-use-linux

Backend-specific Linux guidance for `computer_use_remote`. Load after `status` or `start_session` reports backend_family `linux`, backend_id `wayland`, or AT-SPI features. Covers AT-SPI structural targeting, Wayland portal caveats, and screenshot verification.

Quality

Content

82%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.

The body is a tight, highly actionable guide with concrete tool-call examples and pervasive validation/feedback loops for risky computer-use actions. It is well-structured but kept entirely inline with no external references.

DimensionReasoningScore

Conciseness

Lean and directive with no concept-explanation padding and concrete tool calls throughout, but a few explanatory sentences ('Use it to choose a target, not as final visual proof') could be trimmed.

4 / 5

Actionability

Copy-paste-ready JSON tool-call examples for ax_snapshot and ax_action, concrete operation lists, explicit targeting options, named error codes, and specific shortcuts cover the common cases fully.

5 / 5

Workflow Clarity

Explicit validation checkpoints (screenshot proof after every state change, focus_verified=true) and error-recovery feedback loops ('take a fresh snapshot before trying coordinates') are present, though the sequence is distributed across sections rather than a single ordered checklist.

4 / 5

Progressive Disclosure

Well-organized into clear sections (AT-SPI Targeting, Wayland Notes, Permissions) with no bundle files to reference, but the ~90-line single-file body has minor organization gaps versus an ideal split.

Description

80%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.

The description is highly specific and distinctive with explicit load-trigger guidance and clear capability coverage. Its main weakness is that trigger terms are technical tool-state phrases rather than natural user language.

DimensionReasoningScore

Specificity

Lists several concrete capabilities ('AT-SPI structural targeting, Wayland portal caveats, and screenshot verification') with minor coverage gaps rather than a fully comprehensive action list.

4 / 5

Completeness

Explicitly answers both what ('Backend-specific Linux guidance... Covers AT-SPI structural targeting, Wayland portal caveats, and screenshot verification') and when ('Load after status or start_session reports backend_family linux...'), with concrete trigger guidance.

5 / 5

Trigger Term Quality

Relevant keywords appear (Linux, Wayland, AT-SPI) but they are tool-state/technical terms rather than the natural phrases a user would say, missing common variations.

3 / 5

Distinctiveness Conflict Risk

A clear niche (Linux/Wayland AT-SPI backend) with distinct, tool-reported triggers and implicit exclusion of other backends, giving minimal conflict risk.
