35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill reads more like an architectural decision guide than an actionable skill file. It clearly articulates when to use which API surface and what anti-patterns to avoid, which is valuable framing. However, it critically lacks any executable code examples—no FileProvider XML configuration, no Photo Picker ActivityResultContract setup, no share intent construction—making it difficult for Claude to produce correct implementations from this skill alone.
Suggestions
Add concrete, executable code examples for the core APIs: Photo Picker registration with ActivityResultContracts.PickVisualMedia, FileProvider XML setup and URI generation, and share-sheet Intent construction with FLAG_GRANT_READ_URI_PERMISSION.
Include a minimal FileProvider XML configuration snippet (file_paths.xml + AndroidManifest provider declaration) since this is a common source of errors.
Add explicit validation steps with concrete checks, e.g., verifying the returned URI is non-null, checking grantUriPermission success, and testing MIME type resolution before sharing.
Consider creating a companion REFERENCE.md with full code samples for each API surface (Photo Picker, SAF, FileProvider, chooser) and link to it from the main skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is reasonably efficient but includes some sections that are more descriptive than instructive (e.g., the Guardrails and Anti-Patterns sections overlap significantly in content). The workflow section describes principles rather than concrete steps, adding some verbosity without proportional value. | 2 / 3 |
Actionability | The skill lacks any concrete code examples, specific commands for implementation, or executable snippets. It describes what to do conceptually (e.g., 'Choose the narrowest platform surface first') but never shows how—no FileProvider XML config, no Kotlin/Java code for Photo Picker, no manifest snippets, no share intent construction. The example commands reference project directories but don't teach anything actionable about the APIs themselves. | 1 / 3 |
Workflow Clarity | The workflow has a numbered sequence with a logical progression from asset selection through validation, but the steps are abstract principles rather than concrete actions. There are no explicit validation checkpoints with commands or code—step 4 mentions validating return flows but doesn't show how. For a skill involving URI grants and file sharing (which can fail silently), the lack of concrete validation steps is a gap. | 2 / 3 |
Progressive Disclosure | The skill references handoff skills and official documentation links, which is good. However, it doesn't reference any detailed companion files (e.g., a REFERENCE.md for FileProvider XML templates, or an EXAMPLES.md with full code samples). The examples section points to project directories but doesn't explain what's in them. The content that is present could benefit from splitting detailed API guidance into referenced files. | 2 / 3 |
