summarize-skill: Task Summarization, Simplification, and Handover for DSH Coding Agents

The DSH plugin `gtbwpkwjnb-alt/summarize-skill` is a task summarization skill designed for coding agents, used for status confirmation, context compression, and cross-task handoffs in long sessions. Based on the MIT license, the plugin defaults to read-only and does not automatically modify files or system states; it only writes to local files when explicitly instructed to "save". Its core functions include generating high-density fact-based reports, categorizing issues by priority, and conducting evidence-based risk observations. The plugin supports various trigger phrases such as "summarize", "condense", "handover", and "diagnose", and introduces a fact-layering mechanism to differentiate the credibility of information such as observations, confirmations, and inferences. It can be added via the `dsh plugin` command during installation and can be lazily loaded in settings after restarting. Typical scenarios include quickly checking progress, compressing the current session context, and generating copyable summaries.
