Install

From the author

Use when the user asks about content in their OpenKB knowledge base — research topics, concepts compiled from their documents, cross-document synthesis — or mentions `openkb`, an `.openkb/` directory, or a `wiki/` tree generated by openkb. The user may invoke you from any working directory; the active KB resolves via `openkb status`. Do NOT use for arbitrary Markdown directories, Obsidian vaults, or documentation sites not built by openkb.

Install

Each tab says whether it installs commit 13f93d9, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

If Claude Code was already running and this created the skills folder, run /reload-skills.

Pinned to commit 13f93d9, the one we checked.

Skills in the Claude apps belong to your account rather than to a project.

Make openkb.zip, with the skill folder at the top level:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/yuezhiai/jonex.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 13f93d97c838df42d9c0a370c70ddd81f4b72386 &&
  git -C "$tmp" sparse-checkout set -- Reference/OpenKB/skills/openkb &&
  git -C "$tmp" checkout -q 13f93d97c838df42d9c0a370c70ddd81f4b72386 &&
  out="$(mktemp -d)" &&
  cp -R "$tmp"/Reference/OpenKB/skills/openkb "$out"/openkb &&
  (cd "$out" && zip -qr - openkb) > openkb.zip &&
  rm -rf "$tmp" "$out"

In Claude, open Customize > Skills, select +, then + Create skill > Upload a skill, and choose openkb.zip.

On Free, Pro and Max plans, turn on Code execution and file creation (Create and edit files in newer settings) under Settings > Capabilities.

Or install it with gh skill, which also installs the commit we checked. Needs GitHub CLI 2.90 or later.

gh skill install yuezhiai/jonex Reference/OpenKB/skills/openkb/SKILL.md@13f93d97c838df42d9c0a370c70ddd81f4b72386 --agent github-copilot --scope project

Gemini CLI docs

Pinned to commit 13f93d9, the one we checked.

Codex, Cursor, Copilot, VS Code, Gemini CLI, OpenCode, Goose, Amp and Zed all read .agents/skills; Claude Code and Kiro list only their own folders.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/yuezhiai/jonex.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 13f93d97c838df42d9c0a370c70ddd81f4b72386 &&
  git -C "$tmp" sparse-checkout set -- Reference/OpenKB/skills/openkb &&
  git -C "$tmp" checkout -q 13f93d97c838df42d9c0a370c70ddd81f4b72386 &&
  mkdir -p .agents/skills &&
  mkdir .agents/skills/openkb &&
  cp -R "$tmp"/Reference/OpenKB/skills/openkb/. .agents/skills/openkb/ &&
  rm -rf "$tmp"

Or use the skills CLI from skills.sh. Installs the latest version, not the one we checked. The skills CLI reports installs to skills.sh unless you set DISABLE_TELEMETRY=1.

Agent Skills docs

What it can touch

From the files and frontmatter at commit 13f93d9. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

Runs shell commands
Its instructions or files give the agent commands to run on your computer.

We checked every text file in this skill, at commit 13f93d9 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check works Report an incorrect finding

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Note
  There is no license field, so readers can't tell whether they may reuse the skill. O2
  Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Note
  Reference files over 100 lines with no table of contents at the top: references/wiki-schema.md (144 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
  Reference files over 100 lines with no table of contents at the top: references/wiki-schema.md (144 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
  The description is 443 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
  Reference files over 100 lines with no table of contents at the top: references/wiki-schema.md (144 lines). B5
  Fix: Add a short list of the sections at the top of each.
OpenAI (Codex & API)Passes

openkb-deck-editorial
yuezhiai/jonex
Use when the user asks the openkb chat to make a deck / slide presentation / PPT / slides / 演示稿 / 幻灯片 from their compiled KB content. Generates a polished single-file HTML deck in the Editorial Monocle visual direction (warm cream background, serif type, brick-red accent) — designed to be opened in a browser, full-screened, and shared. Does NOT apply to generating skills (that's `openkb skill new`), long-form research reports, or interactive prototypes.

openkb-deck-neon
yuezhiai/jonex
Use when the user asks the openkb chat to make a deck / slide presentation / PPT / slides / 演示稿 / 幻灯片 from their compiled KB content AND wants a dark, high-tech, neon / glow / glassmorphism look (赛博 / 科技风 / 暗色 / 霓虹 / 炫酷). Generates a polished single-file HTML deck in the Aurora Glass visual direction (near-black background, teal/sky/magenta/amber neon accents, glassmorphism panels, aurora gradient atmosphere) — opened in a browser, full-screened, shared. For the warm, printed, serif look use openkb-deck-editorial instead. Does NOT apply to generating skills (`openkb skill new`), research reports, or scrolling long-form documents.

openkb-html-critic
yuezhiai/jonex
Use to review a generated HTML deck or single-page artifact for visual quality and structural correctness. Especially good at catching CSS specificity bugs where slide-modifier classes (.divider, .center, .q, .flow etc.) accidentally override the base .slide{display:none} and cause one slide to stack on top of every other. Also catches missing keyboard navigation, bullet-dump / wall-of-text failure modes, broken self-containment (external link/script/img). Patches the file in place; never changes the original content (slide text, numbers, named entities are the author's work, not yours).
