 name: using-projects-meta
+author: ours
 version: 1.2.0
 description: Use when working across multiple projects on one or many machines — cross-project task aggregation (`mcp__projects-meta__tasks_*`), shared Gitea-backed wiki query / ingest (`mcp__projects-meta__knowledge_*`), or sync diagnostics (`mcp__projects-meta__meta_status`). Triggers on phrases like "across all projects", "what's on the boards", "check shared wiki", "search projects-wiki", "ingest into shared wiki", "что у меня на досках", "по всем проектам", "общая вики", "cross-project status", or any time the user wants to see / mutate state in another repo than the current cwd. v1.1.0 mandates a Step 0 freshness gate (probe `meta_status`, sync if stale, pull `projects-wiki` before shared-wiki writes) — see SKILL body. Mutation tools require two-step preview → confirm. Skip for the **current** project's tasks/wiki — those live on disk in `.tasks/` / `.wiki/`.
