computer-health-check

Run a comprehensive, read-only health check on the user's computer and return a scored chat summary with prioritized, plain-English recommendations and safe cleanup suggestions. Use this whenever the user wants to check their computer's health, speed it up, free up / reclaim disk space, find what's eating CPU / memory / storage, check battery health and wear, audit login & startup items, see pending updates, or asks for a "tune-up", "checkup", "system report", "health check", or "is my Mac/PC/laptop healthy". Trigger even on casual phrasing like "my laptop feels slow", "why is my fan so loud", "my computer is laggy", "running out of space", or "clean up my machine". Works on macOS, Windows, and Linux. This is a Desktop Commander skill: it relies on a real local shell (start_process / interact_with_process) and is strictly read-only by default — it never needs sudo and only performs cleanups the user explicitly approves.

Quality

Content

78%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.

A well-structured, actionable skill body with a clear multi-step workflow, strong safety framing, and excellent progressive disclosure via three parallel OS reference files. The main improvement area is trimming light motivational prose for token efficiency.

Suggestions

Tighten rhetorical padding such as 'the way a good technician would: look first, explain plainly, fix only with permission' and 'This is the part that makes users trust the skill, so honor it strictly' to the bare safety rules, saving tokens without weakening the contract.

Consider inlining the score formula's edge cases (e.g., what counts toward the floor-0 cap when many categories are 🔴) so Claude does not have to infer the cap behavior on large red counts.

Add a one-line explicit validation/re-confirmation step after each approved cleanup (the body mentions re-running the storage check as 'a nice confirmation' — promote it to a required checkpoint for consistency).

DimensionReasoningScore

Conciseness

Mostly efficient and assumes Claude's competence (no basic explanations of disks, batteries, or processes), but contains light motivational padding ('the way a good technician would', 'This is the part that makes users trust the skill, so honor it strictly') that could be trimmed without losing the safety contract.

4 / 5

Actionability

Provides a concrete report template, an exact scoring formula (100 - 8 per 🟡 - 18 per 🔴), and specific cleanup commands (e.g. 'brew cleanup', 'Clear-RecycleBin -Force'); the bulk of executable collection scripts lives in the referenced files rather than inline, leaving minor gaps in the body itself.

4 / 5

Workflow Clarity

A clear five-step sequence (Detect OS -> Collect -> Score -> Report -> Suggest/Execute) with explicit safety checkpoints and approval gates; partial-data and error handling are addressed ('If a single command errors... continue'). It lacks a formal validate->fix->retry feedback loop, but the operations are read-only/batched with approval-based execution rather than destructive edits, so the destructive-cap exception does not apply.

4 / 5

Progressive Disclosure

The body is a concise overview that delegates OS-specific command sets to three clearly signaled, one-level-deep reference files via markdown links, with an explicit 'read only the one that matches' instruction; the referenced files exist and mirror the same categories, giving easy navigation.

Description

100%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.

An exemplary description: concrete capabilities, rich natural trigger terms, explicit what-and-when guidance, and a clearly scoped niche with minimal conflict risk. It also bakes in safety framing (read-only, no sudo, opt-in cleanups) without sacrificing brevity.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('run a comprehensive, read-only health check', 'return a scored chat summary with prioritized... recommendations and safe cleanup suggestions') and enumerates specific audit areas (CPU/memory/storage, battery health and wear, login & startup items, pending updates), giving comprehensive coverage.

5 / 5

Completeness

Explicitly answers both 'what' (read-only health check returning a scored summary with recommendations and cleanup suggestions) and 'when' ('Use this whenever the user wants to check their computer's health, speed it up...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural phrasings including casual forms users actually say ('my laptop feels slow', 'why is my fan so loud', 'running out of space') plus named trigger words ('tune-up', 'checkup', 'system report', 'health check', 'is my Mac/PC/laptop healthy') and synonyms across platforms.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (cross-platform computer health check) with distinct, OS-specific triggers and an explicit scope statement ('This is a Desktop Commander skill... strictly read-only by default') that minimizes overlap with general system or file skills.
