dsh-skills-manager-plugin

The built-in DSH skill tool asks the model to notice a short summary and decide on its own whether to load the full skill. In practice, useful skills are frequently missed, skill files cannot declare lifecycle behavior, and locally scattered skill directories are hard to keep in sync. dsh-skills-manager closes those gaps: before every agent step it scores available skills across three tiers, auto-injecting full content for strong matches and surfacing lightweight reminders for weaker ones, so capabilities activate at the moment they are actually needed.

Three capability layers stand out. The proactive matching engine stores activation markers in conversation history to prevent duplicate injection and allows automatic re-loading after context compaction. The skill-level hook orchestration maps UserPromptSubmit, PreToolUse, PostToolUse, and SessionStart declarations onto DSH host events with allow, deny, or ask tool policies, and hooks never run through a shell. GitHub-driven skill management supports shallow cloning, automatic SKILL.md discovery, authoritative sync, and commit-change reporting, while project-scope skill roots take priority over user-level ones so configurations never leak across workspaces.

Built for developers and teams who have accumulated a growing set of SKILL.md files in DeepSeek Harness and want skills to activate proactively, stay version-managed, and carry declarative lifecycle behavior without modifying DSH core.
