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 fails to describe any concrete capabilities, lacks natural trigger terms users would use, and provides no guidance on when Claude should select this skill. It would be nearly useless for skill selection in a multi-skill environment.
Suggestions
Add specific concrete actions the skill covers, e.g., 'Creates Dockerfiles, builds images, runs and manages containers, configures port mappings and volumes.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks about Docker, containers, Dockerfiles, docker-compose, images, docker run, or container orchestration basics.'
Remove the redundant duplicate trigger term and replace with varied natural language terms users would actually say (e.g., 'Dockerfile', 'docker build', 'container setup', 'docker image').
| 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 | Neither the 'what does this do' nor the 'when should Claude use it' questions are meaningfully answered. There is no 'Use when...' clause and no description of capabilities. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are the redundant 'docker container basics' repeated twice. It misses natural user terms like 'Dockerfile', 'docker run', 'docker compose', 'containers', 'images', 'docker build', 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 scoping details 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 with placeholder text that provides no actual Docker container knowledge or guidance. It contains no commands, no code, no examples, and no actionable instructions. It reads as auto-generated boilerplate that describes what a skill should do without actually doing it.
Suggestions
Replace the meta-description sections with actual Docker commands and examples (e.g., `docker run`, `docker build`, `docker ps`, Dockerfile syntax with a concrete example)
Add a quick-start workflow with concrete steps: write a Dockerfile, build an image, run a container, verify it's running, with exact commands for each step
Include at least one complete, executable Dockerfile example with a build and run command pair
Add common troubleshooting patterns (e.g., container won't start, port conflicts, volume mounting issues) with specific diagnostic commands
| 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 describing the skill rather than teaching anything. | 1 / 3 |
Actionability | There is zero concrete guidance—no Docker commands, no code examples, no Dockerfiles, no configurations. The content only describes what it could do ('provides step-by-step guidance') without actually providing any. | 1 / 3 |
Workflow Clarity | No workflow, steps, or processes are defined. There are no sequences, no validation checkpoints, and no actual instructions for any Docker container task. | 1 / 3 |
Progressive Disclosure | The content has section headers but they contain no substantive information. There are no references to detailed files, no examples to navigate to, and the structure is purely cosmetic with no real content to organize. | 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.
