by pluginagentmarketplace
Agile product management, Scrum practices, and team collaboration for iterative product development.
executor
by mrsknetwork
Strictly and autonomously implements a single task item from a planner-generated checklist. Enforces the rule of exploring before writing, applying atomic edits, running self-validation, and reporting status. Use this skill when a specific task item is ready to be implemented. Always use executor for individual checklist items rather than trying to implement everything in one shot.
llm-jailbreaking
