docker

Execute research code inside isolated Docker containers for safe replication, experiments, and benchmarks. Use when the user selects Docker as the execution environment or asks to run code safely, in isolation, or in a sandbox.

Quality

Content

76%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.

Highly actionable with executable Docker commands for the common research scenarios, but the workflow lacks validation checkpoints for safely running untrusted code, and a small amount of redundancy slightly undercuts conciseness.

Suggestions

Add an explicit validation/verification checkpoint after running commands (e.g., check container exit code or confirm expected output files exist before declaring success), especially since the skill targets untrusted research code.

Collapse the 'How it works' overview or fold it into the concrete command sections to remove redundancy and tighten the token budget.

Add brief error-recovery guidance (e.g., what to do when a build fails, package install conflicts, or GPU is not visible inside the container).

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's Docker knowledge, but the 'How it works' section repeats what the concrete command sections demonstrate, and a few explanatory lines ('This preserves installed packages across iterations') could be trimmed.

4 / 5

Actionability

Provides copy-paste-ready, fully executable commands covering the common cases (Python, Dockerfile builds, GPU workloads, persistent named containers) plus a base-image selection table and cleanup steps.

5 / 5

Workflow Clarity

The 'How it works' section gives a clear four-step sequence, but there are no validation or verification checkpoints for running untrusted/batch research code, and no error-recovery guidance.

3 / 5

Progressive Disclosure

A single self-contained file with well-organized sections and no need for external references; slightly over 50 lines and the 'How it works' overview is somewhat redundant with the detailed sections below.

Description

83%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 strong, third-person description that clearly conveys both capability and trigger conditions with concrete, natural-language terms. Minor overlap risk on the generic 'sandbox/isolation' triggers is the main weakness.

DimensionReasoningScore

Specificity

Names the domain ('research code inside isolated Docker containers') and several concrete use cases ('safe replication, experiments, and benchmarks'), but the actions are framed more as scenarios than distinct operations, leaving minor coverage gaps.

4 / 5

Completeness

Explicitly states both what it does ('Execute research code inside isolated Docker containers...') and when to use it ('Use when the user selects Docker... or asks to run code safely, in isolation, or in a sandbox') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural terms a user would say ('Docker', 'run code safely', 'in isolation', 'sandbox') with good coverage; missing a few synonyms like 'containerize'.

4 / 5

Distinctiveness Conflict Risk

Tied to a clear Docker-specific niche, but 'sandbox' and 'in isolation' triggers could overlap with other sandboxing skills, creating minor conflict risk.
