`sidekick` Skill#

The sidekick skill instructs Claude to run sdkck search before reaching for any MCP server, shell command, or external API. It is auto-triggered — you do not invoke it manually.

MCP server vs. skill#

Both the MCP server and this skill connect your agent to Sidekick — pick one, not both.

	MCP server	`sidekick` skill
How	Exposes sdkck as MCP tools (`search_tools`, `run_command`)	Instructs the agent to run sdkck CLI via shell

Installation#

Claude Code#

claude plugin marketplace add hesedcasa/sdkck
claude plugin install sidekick@cli

npx skills add hesedcasa/sdkck --skill sidekick -g

Target a specific agent:

npx skills add hesedcasa/sdkck --skill sidekick -a cursor
npx skills add hesedcasa/sdkck --skill sidekick -a codex
npx skills add hesedcasa/sdkck --skill sidekick -a opencode

What it does#

Whenever Claude is about to call a tool that touches an external system, the skill kicks in and runs a discovery step first:

sdkck search "jira issue create"

If Sidekick has a matching command, Claude uses it instead. Only when the search returns no relevant match does Claude fall back to other tools.

Covered systems#

User mentions…	Sidekick searches for…
Jira, ticket, issue, epic, sprint	`sdkck search "jira <keyword>"`
Sentry, error, event, exception	`sdkck search "sentry <keyword>"`
SQL, DB, query, table, schema	`sdkck search "mysql"` / `"postgres"`
Supabase, auth user, row-level	`sdkck search "supabase <keyword>"`
Confluence, wiki, page, space	`sdkck search "confluence <keyword>"`
Bitbucket, PR, repo, branch	`sdkck search "bitbucket <keyword>"`
Any imported API / Postman collection	`sdkck search "<api name or operation>"`
Anything else touching external systems	Search anyway — empty results mean fallback

Core workflow#

sdkck search "create jira issue"   # 1. Discover
sdkck jira issue create --help     # 2. Inspect
sdkck jira issue create ...        # 3. Run

Example#

Agent: I need to check recent Sentry errors and create a Jira ticket.

> sdkck search "sentry errors"          # Discovers the right command
> sdkck sentry issues list --recent     # Gets the data
> sdkck jira issue create ...           # Acts on it
