diffs
The diffs tool generates shareable unified diffs in multiple formats: interactive viewer URLs, file artifacts (PNG or PDF), or both combined. Use this skill when presenting code changes, edits, or comparisons that require visual clarity beyond written summaries, particularly for code reviews, documentation of changes, or delivery to users through message or canvas tools.

When you need to show edits as a real diff, prefer the `diffs` tool instead of writing a manual summary. The `diffs` tool accepts either `before` + `after` text, or a unified `patch` string. Use `mode=view` when you want an interactive gateway-hosted viewer. After the tool returns, use `details.viewerUrl` with the canvas tool via `canvas present` or `canvas navigate`. Use `mode=file` when you need a rendered file artifact. Set `fileFormat=png` (default) or `fileFormat=pdf`. The tool result includes `details.filePath`. For large or high-fidelity files, use `fileQuality` (`standard`|`hq`|`print`) and optionally override `fileScale`/`fileMaxWidth`. When you need to deliver the rendered file to a user or channel, do not rely on the raw tool-result renderer. Instead, call the `message` tool and pass `details.filePath` through `path` or `filePath`. Use `mode=both` when you want both the gateway viewer URL and the rendered artifact. If the user has configured diffs plugin defaults, prefer omitting `mode`, `theme`, `layout`, and related presentation options unless you need to override them for this specific diff. Include `path` for before/after text when you know the file name.
Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Transparent, rigorous research with full methodology — not a black-box API wrapper. Conducts exhaustive investigation through mandated 2-cycle research per theme, APA 7th citations, evidence hierarchy, and 3 user checkpoints. Self-contained using native OpenClaw tools (web_search, web_fetch, sessions_spawn). Use for literature reviews, competitive intelligence, or any research requiring academic rigor and reproducibility.
# Academic Literature Search — 学术文献检索与引用管理
Route plain-language requests for Pi, Claude Code, Codex, OpenCode, Gemini CLI, or ACP harness work into either OpenClaw ACP runtime sessions or direct acpx-driven sessions ("telephone game" flow). For coding-agent thread requests, read this skill first, then use only `sessions_spawn` for thread creation.
Manage Apple Notes via the `memo` CLI on macOS (create, view, edit, delete, search, move, and export notes). Use when a user asks OpenClaw to add a note, list notes, search notes, or manage note folders.
Manage Apple Reminders via remindctl CLI (list, add, edit, complete, delete). Supports lists, date filters, and JSON/plain output.
Write articles, guides, blog posts, tutorials, newsletter issues, and other long-form content in a distinctive voice derived from supplied examples or brand guidance. Use when the user wants polished written content longer than a paragraph, especially when voice consistency, structure, and credibility matter.
Search and retrieve preprints from arXiv via the Atom API. Use this skill when searching for papers in physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering, or economics by keywords, authors, arXiv IDs, date ranges, or categories.
