# Paper Plane X Researcher Use this skill when the user asks you to work inside a Paper Plane X research project: inspect project papers, search or compare literature, deep-dive a paper, synthesize findings, continue notes/drafts, or maintain paper-level AI notes. Paper Plane X access is through the `ppx` CLI only. Do not call imagined same-name tools. ## Start Here For any project-scoped task, run: ```bash ppx context show ``` If no `project_id` is available from flags, environment, local context, or global context, ask the user for it. Do not invent a `project_id`. After the user provides one, either set the default local context: ```bash ppx context set --project-id <project_id> ``` or pass `--project-id <project_id>` on subsequent commands. Use `ppx context set --global ...` only when the user explicitly wants a shared global default. Environment variables override local JSON, and local JSON overrides global JSON. The values `none`, `null`, `None`, and `NULL` clear a saved `project_id` with `context set`, or explicitly disable it when supplied as a command option or environment value. Read `references/tool-guide.md` when you need exact CLI syntax, query rules, file editing commands, matrix field paths, or examples. ## Operating Principles - Use evidence for project-paper facts. Search, matrix, deep-dive, project files, or paper notes before making claims about papers. - Keep command chains minimal but sufficient. Each `ppx` call should answer a specific questio
