Discovery
0%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is essentially a title and category label with no substantive content. It lacks any concrete actions, natural trigger terms, explicit usage guidance, or distinguishing details. It would be nearly useless for Claude to select this skill appropriately from a pool of available skills.
Suggestions
Add specific concrete actions the skill covers, e.g., 'Creates Dockerfiles, builds and runs containers, manages images, troubleshoots container issues.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks about Docker, containers, Dockerfiles, docker run, docker build, container orchestration basics, or .dockerfile files.'
Remove the duplicate trigger term 'docker container basics' and replace with varied natural keywords users would actually say, such as 'Docker', 'container', 'image', 'Dockerfile', 'docker-compose'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description contains no concrete actions whatsoever. It merely names the topic 'Docker Container Basics' without describing what the skill actually does (e.g., create containers, manage images, write Dockerfiles). | 1 / 3 |
Completeness | The description fails to answer both 'what does this do' and 'when should Claude use it.' There is no explanation of capabilities and no explicit 'Use when...' clause or equivalent trigger guidance. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'docker container basics' repeated twice. There are no natural keyword variations a user might say, such as 'Dockerfile', 'docker run', 'container', 'image', 'docker-compose', etc. | 1 / 3 |
Distinctiveness Conflict Risk | The description is extremely generic — 'Docker Container Basics' could overlap with any Docker-related skill. There are no distinct triggers or specific scope boundaries to differentiate it from other DevOps or Docker skills. | 1 / 3 |
Total | 4 / 12 Passed |
Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty shell—a template of meta-descriptions with no actual Docker container content. It contains no commands, no code, no Dockerfiles, no examples, and no actionable guidance whatsoever. It would provide Claude with zero useful information for helping users with Docker container tasks.
Suggestions
Replace the meta-description sections with actual Docker content: key commands (docker run, docker build, docker ps, docker exec), a minimal Dockerfile example, and container lifecycle management.
Add concrete, executable code examples such as a sample Dockerfile and docker-compose.yml with copy-paste ready commands.
Include a workflow for building and running containers with validation steps (e.g., checking container health, verifying port mappings, inspecting logs for errors).
Remove all self-referential boilerplate ('This skill activates when...', 'Example Triggers') and replace with lean, actionable Docker knowledge that Claude doesn't already know.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and meta-description. It explains what the skill does in abstract terms without providing any actual Docker container knowledge, commands, or configurations. Every token is wasted on boilerplate that teaches Claude nothing. | 1 / 3 |
Actionability | There is zero concrete guidance—no Docker commands, no Dockerfiles, no code examples, no specific instructions. The content only describes itself rather than instructing Claude on how to perform any Docker-related task. | 1 / 3 |
Workflow Clarity | No workflow, steps, or processes are defined. Claims like 'provides step-by-step guidance' and 'validates outputs' are made but never substantiated with any actual steps or validation procedures. | 1 / 3 |
Progressive Disclosure | The content has section headers but they contain only vague descriptions. There are no references to detailed files, no structured navigation, and no meaningful content to organize in the first place. | 1 / 3 |
Total | 4 / 12 Passed |
Validation
81%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
