Discovery
7%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 placeholder with no substantive content. It repeats the skill name as its only trigger term, provides no concrete actions or capabilities, and lacks any explicit guidance on when Claude should select this skill. It would be nearly indistinguishable from any other backend scheduling skill.
Suggestions
Add specific concrete actions such as 'Creates and validates cron expressions, configures scheduled tasks, parses crontab syntax, and manages recurring job schedules.'
Add a 'Use when...' clause with natural trigger terms like 'Use when the user asks about crontab, scheduled tasks, recurring jobs, cron expressions, task scheduling, or periodic execution.'
Remove the duplicate trigger term and expand with natural language variations users would actually say, such as 'crontab', 'schedule a task', 'recurring job', 'periodic task', 'cron syntax'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the domain ('Cron Job Scheduler') without listing any concrete actions. There are no specific capabilities described such as 'create cron expressions', 'schedule tasks', 'parse crontab syntax', etc. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name itself, and there is no explicit 'when to use' clause. The 'Triggers on' line is just a duplicate of the skill name, not meaningful trigger guidance. | 1 / 3 |
Trigger Term Quality | The only trigger term listed is 'cron job scheduler' repeated twice. It misses natural variations users would say like 'crontab', 'scheduled task', 'cron expression', 'recurring job', 'task scheduling', or 'cron syntax'. | 1 / 3 |
Distinctiveness Conflict Risk | The term 'cron job scheduler' is somewhat specific to a niche domain, which provides some distinctiveness. However, the lack of concrete actions and the generic 'Backend Development' category could cause overlap with other backend-related skills. | 2 / 3 |

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 template with no substantive content about cron job scheduling. It contains only generic boilerplate text that provides no actionable guidance, no code examples, no cron syntax reference, and no workflow for creating or managing cron jobs. It would need to be completely rewritten to be useful.
Suggestions
Add concrete cron syntax reference (e.g., `* * * * *` field meanings) and executable code examples for common schedulers like node-cron, APScheduler, or Go's robfig/cron
Include a clear workflow for setting up a cron job: define schedule → implement handler → add logging/error handling → validate with dry run → deploy → monitor
Add production-ready patterns such as distributed locking to prevent duplicate execution, idempotency, failure alerting, and graceful shutdown handling
Remove all generic boilerplate sections ('When to Use', 'Example Triggers', 'Capabilities') and replace with actual technical content that Claude doesn't already know
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and boilerplate. It explains nothing Claude doesn't already know, contains no domain-specific information about cron jobs, and every section is generic template text that could apply to any skill. | 1 / 3 |
Actionability | There is zero concrete guidance—no cron syntax, no code examples, no commands, no library recommendations, no configuration snippets. It describes rather than instructs, offering only vague phrases like 'provides step-by-step guidance' without actually providing any. | 1 / 3 |
Workflow Clarity | No workflow, steps, or process is defined at all. There is no sequence of actions, no validation checkpoints, and no error handling guidance for setting up or managing cron jobs. | 1 / 3 |
Progressive Disclosure | The content is a monolithic block of generic text with no references to supporting files, no structured navigation, and no separation of overview from detailed content. There are no bundle files to reference either. | 1 / 3 |
