OpenKit Skills

OpenKit's collection of Agent Skills — reusable, model-invoked capabilities built on the open SKILL.md standard, so they work across Claude (Code, Cowork, claude.ai), Codex / ChatGPT, Cursor, Gemini CLI, Copilot, and any other agent that reads SKILL.md.

This repo is set up so the same GitHub repo works for both the cross-tool npx skills installer and the native Claude Code plugin marketplace. Pick whichever route your users prefer.

⬇️ Download the skills (no repo to clone, no sifting)

One link, skills only. Unzipping gives a flat list of three .md files — one per skill, nothing to click through.

Download — the link for the website:

https://github.com/OpenKit-Ltd/skills/releases/latest/download/openkit-inbox-skills.zip

Unzip and you get, side by side:

build-user-context.md
inbox-triage.md
build-inbox-voice.md

In Claude's web/desktop app, add each one under Customize → Skills (start with build-user-context — the other two build on it). For Claude Code, use npx skills add or /plugin from the Install section below instead; those pull straight from the repo.

Claude Cowork plugin file — openkit-tools-plugin.zip installs all three as one plugin via Cowork's "upload a custom plugin file":

https://github.com/OpenKit-Ltd/skills/releases/latest/download/openkit-tools-plugin.zip

These releases/latest/download/… URLs are permanent — they always serve the newest release, so hard-code them on the OpenKit site once and never touch them again. A new release is cut whenever a v* tag is pushed (CI rebuilds these artifacts). See CONTRIBUTING.md.

Install

Option 1 — npx skills (easiest, works across 30+ agents)

npx skills add OpenKit-Ltd/skills

No Claude session required, no restart — it drops the skills into the right place for whichever agent you have installed. Add -g for a global (all-projects) install, or --list to preview what's in the repo first.

Option 2 — Claude Code plugin marketplace (versioned + auto-updating)

/plugin marketplace add OpenKit-Ltd/skills
/plugin install openkit-tools@openkit

Then run a skill directly, e.g. /openkit-tools:inbox-triage. Update later with /plugin marketplace update openkit.

Option 3 — Claude web & desktop (no CLI, no commands)

No commands — you add each skill through the UI:

1. Download openkit-inbox-skills.zip (link at the top) and unzip it — you get three .md files (build-user-context.md, inbox-triage.md, build-inbox-voice.md).
2. In Claude, go to Customize → Skills and add each one. Start with build-user-context, since the other two build on it.

For teams: on Team/Enterprise plans an org owner can add the skills once under Organization settings → Skills so they appear automatically for everyone.

Option 4 — Claude Cowork (installs every skill at once)

Cowork installs plugins (bundles of skills), so a single install delivers the whole kit — no picking skills one by one. Two ways:

• Add marketplace from GitHub (nothing to download): Cowork → Customize → Plugins → + → Add marketplace → enter OpenKit-Ltd/skills → install openkit-tools. Every skill becomes available immediately (type / in chat or Cowork to see them).
• Upload the plugin file: download openkit-tools-plugin.zip from Releases and use the upload option on the Plugins page.

For teams: an org owner can distribute the marketplace org-wide and mark the plugin as required / auto-installed, so everyone gets all the skills with zero manual steps.

Maintainers: rebuild the download artifacts locally with bash scripts/build-skill-zips.sh (outputs to dist/). CI does this automatically on each v* tag and attaches them to the matching GitHub Release.

Available skills

These three skills make up the OpenKit Inbox suite. Set them up in order — start with build-user-context, which the other two depend on.

Skill	What it does
build-user-context	Run first. Interviews you and researches your email to generate your personalised user-context skill — who you are, who you work with, the projects that matter, and how you write. Prerequisite for the rest.
inbox-triage	Reads your inbox over a chosen window and returns a structured brief — Urgent / Watching / Skip — as colour-coded priority cards that expand on click. Read-only; never drafts or sends. Uses user-context.
build-inbox-voice	Analyses your sent/received threads to build an inbox-reply-drafter skill that writes replies in your voice. Uses user-context.
