Cekura Skills

Cekura skills give your AI coding agent the playbook for designing evaluators, creating metrics, running tests, and triaging results on the Cekura platform. They auto-activate when your conversation matches a relevant task.

What you get

Nine skills, scoped to specific Cekura workflows:

Skill	Activates on
`cekura-coordinator`	”What can Cekura do?” — routes to the right skill
`cekura-onboarding`	”Get started with Cekura” — full platform walkthrough
`cekura-create-agent`	”Connect my voice agent to Cekura”
`cekura-self-improving-agent`	”Improve my agent / auto-tune from eval results”
`cekura-metric-design`	”Create a metric / measure call quality”
`cekura-metric-improvement`	”Improve a metric / fix metric accuracy”
`cekura-predefined-metrics`	”What predefined metrics are available / which built-in metrics should I use”
`cekura-eval-design`	”Design test scenarios for my voice agent”
`cekura-fixing-prod-issues`	”Fix a production call bug / reproduce and test a fix before raising a PR”

Best with MCP, but optional. Skills work standalone as a knowledge layer (workflows, design patterns, anti-patterns) and pair best with the Cekura MCP server, which lets the agent perform platform actions for you. Without MCP, the agent walks you through direct API calls or dashboard steps. See MCP overview for setup.

Install

Claude Code users — install the marketplace plugin. It bundles all 9 skills, 14 slash commands, the MCP server config, and a failure-detection hook in a single install. Other agents (Cursor, Codex, Windsurf, etc.) use npx skills add to get the skills only.

Claude Code (recommended)
Other agents (npx skills)

The full marketplace install — skills, slash commands, MCP auto-config, and hooks. This is the recommended path for any Claude Code user.CLI:

Run /plugin inside a Claude Code session
Marketplaces tab → Add Marketplace
Paste https://github.com/cekura-ai/cekura-skills.git and confirm
Discover tab → search cekura → install the cekura plugin
Restart your Claude Code session
Run /setup-mcp to configure the MCP server (or follow the MCP overview for the OAuth flow — it’s a one-click sign-in)

VS Code:

Open the Claude Code chat panel
Manage Plugins → Marketplaces → paste the same URL → Add
Plugins tab → install the cekura plugin
Restart VS Code, then run /setup-mcp

After install you get all 14 commands (/cekura-onboarding, /setup-mcp, /upgrade-skills, /report-bug, /create-metric, /list-metrics, /evaluate-calls, /improve-metric, /autogen-eval, /manual-create-update-eval, /list-evals, /run-evals, /eval-results, /cekura-report) plus the auto-configured MCP server and the MCP-failure detection hook.

For Cursor, Codex, Windsurf, OpenCode, Antigravity, and any other Agent Skills–compatible client. Installs skills only — no slash commands, no auto-MCP-config, no hooks.

npx skills add cekura-ai/cekura-skills

The CLI prompts you to pick which skills to install and which agents to install them into. Install everything non-interactively:

npx skills add cekura-ai/cekura-skills --all

Pair this with the MCP setup — OAuth gives you the same API access as Claude Code without managing keys.

Update / refresh

Claude Code marketplace
Other agents (npx skills)

Run /upgrade-skills in any Claude Code session, or pull manually:

cd ~/.claude/plugins/marketplaces/cekura-skills
git pull origin main

Restart Claude Code after upgrading.

Enable auto-update for hands-off refreshes. Claude Code can auto-refresh marketplaces and installed plugins at startup, but third-party marketplaces are opt-in. Turn it on once and you’re done:

Run /plugin to open the plugin manager
Go to the Marketplaces tab
Select cekura-skills
Choose Enable auto-update

Every Claude Code session will then refresh the marketplace and install the latest plugin versions automatically. If anything updated, you’ll see a prompt to run /reload-plugins.Or set FORCE_AUTOUPDATE_PLUGINS=1 in your shell environment to force auto-update for every marketplace globally.

# Refresh existing skills
npx skills update

# Or refresh existing AND pick up any newly-added skills
npx skills add cekura-ai/cekura-skills --all

Reinstall

If /upgrade-skills reports stale plugin entries, or /plugin install fails with Source path does not exist, your Claude Code install needs a clean reinstall. Run these 4 commands in order in any Claude Code session:

/plugin marketplace remove cekura-skills
/plugin marketplace add cekura-ai/cekura-skills
/plugin marketplace update cekura-skills
/plugin install cekura@cekura-skills

Step 3 is the critical one — it forces Claude Code to re-read the marketplace manifest. After step 4, claude plugin list should show one cekura@cekura-skills entry and all 14 slash commands resolve under cekura:*. If /plugin install still errors after step 4, fully restart Claude Code (close and reopen the session), then redo steps 2–4.

Remove

# npx skills install
npx skills remove cekura-coordinator   # one skill
npx skills remove --all                 # everything

For the Claude Code marketplace install, remove the marketplace from /plugins → Marketplaces.

Frequently asked questions

What are Cekura skills?

Cekura skills are domain-specific instructions that teach AI coding agents how to work with the Cekura platform — designing metrics, building test scenarios, onboarding voice agents, and improving evaluation accuracy. They activate automatically when you describe a relevant task.

Which AI agents are supported?

Any agent that supports the Agent Skills format. Verified compatibility includes Claude Code (VS Code and CLI), Cursor, OpenAI Codex, Antigravity, OpenCode, Amp, Goose, Junie, GitHub Copilot, Roo Code, Letta, Firebender, Mistral Vibe, and others.

Do I need a Cekura account?

Yes — sign up free at dashboard.cekura.ai. OAuth is the default; use an API key only if you need project/org scoping or want to share one credential across CI / teammates.

Should I use the Claude Code plugin install or `npx skills add`?

You want	Use
Full Claude Code experience (slash commands, MCP auto-config, hooks)	Plugin marketplace
Skills only, on Cursor / Codex / Antigravity / any other agent	`npx skills add`
A lighter Claude Code install without slash commands	`npx skills add`

What’s the difference between a skill and a slash command?

Skill — knowledge / behavior the agent loads when you describe a related task (e.g., “design a metric that…”). Works on every Agent Skills-compatible agent.
Slash command — a Claude Code-specific shortcut that performs a specific operation (e.g., /create-metric actually creates a metric via the API). Only available with the Claude Code plugin install.

You can use skills without commands. Commands always come with their corresponding skill.

How do skills activate?

Two ways:

Automatically by description — describe what you want (“create a metric for call quality”), the agent loads the matching skill.
Explicitly — type /skill-name (Cursor, Codex) or mention the skill by name.

Can I customize a skill?

Yes — skills are plain markdown files. After install, edit SKILL.md directly, or fork cekura-ai/cekura-skills and install from your fork:

npx skills add <your-org>/cekura-skills

Are skills shared across my team?

Per-user install in most cases — share the install command in your team’s onboarding doc. The Claude API custom-skills upload path supports workspace-wide sharing once a skill is uploaded.
