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 is an extremely weak description that provides virtually no useful information for skill selection. It reads more like a stub or placeholder than a functional description. It fails on every dimension: no concrete actions, no natural trigger terms, no 'what/when' guidance, and no distinctiveness.
Suggestions
Describe specific concrete actions the skill performs, e.g., 'Generates step-by-step migration plans for database schema changes, including rollback strategies and data transformation scripts.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks about migrating databases, upgrading schemas, planning data moves, or creating migration roadmaps.'
Specify the domain of migration (database, cloud, platform, code, etc.) to make the skill clearly distinguishable from other potential migration-related skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description contains no concrete actions whatsoever. 'Agent skill for migration-plan' is entirely vague—it doesn't describe what the skill actually does, what kind of migration, or any specific capabilities. | 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 'Use when...' clause or equivalent trigger guidance. | 1 / 3 |
Trigger Term Quality | The only potentially relevant keyword is 'migration-plan', which is a hyphenated technical term rather than natural language a user would say. There are no natural trigger terms like 'migrate', 'database migration', 'upgrade', 'move data', etc. | 1 / 3 |
Distinctiveness Conflict Risk | 'Migration-plan' is extremely generic—it could refer to database migration, cloud migration, code migration, data migration, platform migration, or any number of other domains. There is nothing to distinguish this skill from other migration-related skills. | 1 / 3 |

Implementation
14%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 extremely verbose migration reference document that repeats the same YAML agent definition pattern 20+ times inline, consuming massive token budget without proportional value. The actual actionable migration workflow is buried at the bottom in 5 vague steps with no validation or error recovery. The content would be far more effective as a concise template + mapping table with agent definitions split into separate files.
Suggestions
Replace the 20+ inline YAML blocks with a single template example and a summary table mapping command paths to agent names/roles/key tools, moving full definitions to separate files
Expand the 'Migration Steps' section with executable commands (e.g., mkdir commands, file creation scripts) and add explicit validation checkpoints after each step
Add a concrete verification workflow: how to test that a migrated agent works correctly, with specific commands to run and expected outputs to check
Remove explanatory text about what agents, tool restrictions, and inter-agent communication are — focus only on the specific migration procedure and format requirements
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose at 500+ lines, mostly repetitive YAML blocks that follow the same pattern. The document explains obvious concepts (what agents do, what tool restrictions mean) and could be reduced to a template + table mapping commands to agents. Most content is redundant boilerplate. | 1 / 3 |
Actionability | The YAML agent definitions are concrete and specific, providing exact tool names, trigger patterns, and role definitions. However, the actual migration steps (section 4) are vague ('Create directory structure', 'Test agent interactions') with no executable commands or concrete examples of how to perform the migration itself. | 2 / 3 |
Workflow Clarity | The migration steps in section 4 are a brief 5-item list with no validation checkpoints, no error recovery, and no verification that migration succeeded. For a destructive operation like system migration, this completely lacks the feedback loops and validation steps needed. The monitoring section lists metrics but provides no concrete way to measure them. | 1 / 3 |
Progressive Disclosure | This is a monolithic wall of text with 20+ nearly identical YAML blocks inlined. The agent definitions should be in separate files or a reference document, with the SKILL.md providing just the template format, migration workflow, and a summary table mapping commands to agents. | 1 / 3 |
