Validation for skill structure
Activation
7%This description is severely underdeveloped, essentially just restating the skill name without providing any useful information about capabilities or usage triggers. It fails to help Claude understand when to select this skill over others and provides no concrete actions or natural language triggers that users would employ.
Suggestions
Add specific actions the skill performs, e.g., 'Creates optimized Dockerfiles for applications, configures multi-stage builds, sets up base images and dependencies'
Add a 'Use when...' clause with natural trigger terms like 'create dockerfile', 'containerize application', 'docker image', 'container setup', 'docker build configuration'
Remove the redundant duplicate trigger term and replace with varied, natural phrases users would actually say when needing Dockerfile help
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the tool ('Dockerfile Generator') without describing any concrete actions. It doesn't explain what the skill actually does - no mention of creating, configuring, optimizing, or any specific Dockerfile operations. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name, and the 'when' clause is just a redundant repetition of the skill name rather than meaningful trigger guidance. No explicit 'Use when...' clause with actionable triggers. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'dockerfile generator' repeated twice. Missing natural variations users would say like 'create dockerfile', 'docker image', 'containerize', 'docker build', or 'container configuration'. | 1 / 3 |
Distinctiveness Conflict Risk | While 'Dockerfile' is somewhat specific to container technology, the lack of detail about what aspects of Dockerfiles it handles (creation vs optimization vs debugging) could cause overlap with other Docker-related skills. | 2 / 3 |

Implementation
0%This skill content is essentially a placeholder template with no actual Dockerfile generation guidance. It contains only generic meta-descriptions about what the skill supposedly does without providing any concrete instructions, code examples, or actionable content. The entire body could be replaced with actual Dockerfile patterns, multi-stage build examples, and best practices.
Suggestions
Add concrete Dockerfile examples showing common patterns (e.g., Python app, Node.js app, multi-stage builds) with executable, copy-paste ready code
Include specific best practices with examples: layer ordering, .dockerignore usage, security considerations, image size optimization
Provide a clear workflow for Dockerfile generation: 1) Identify base image, 2) Define build steps, 3) Configure runtime, 4) Validate with docker build
Remove all generic boilerplate text ('provides automated assistance', 'follows industry best practices') and replace with actual technical content
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is padded with generic boilerplate that explains nothing Claude doesn't already know. Phrases like 'provides automated assistance' and 'follows industry best practices' are meaningless filler with no actual Dockerfile-specific content. | 1 / 3 |
Actionability | There is zero concrete guidance - no Dockerfile syntax, no code examples, no specific commands, no actual instructions for generating Dockerfiles. The content describes rather than instructs. | 1 / 3 |
Workflow Clarity | No workflow is defined at all. There are no steps, no sequence, no validation checkpoints - just vague claims about 'step-by-step guidance' without actually providing any. | 1 / 3 |
Progressive Disclosure | The content is a monolithic block of generic text with no structure pointing to detailed materials, no references to examples or advanced topics, and no useful organization for a Dockerfile generation skill. | 1 / 3 |
