Tabnine Skills

Agent skills, tools, and integrations for AI coding agents — enabling semantic code search, coding guidelines enforcement, and Context Engine knowledge graph access across Claude Code, Cursor, Gemini CLI, and Tabnine agent.

Plugins

This repo ships two independent plugins with support for four agents. Install what you need:

Plugin	What it does	Claude Code	Cursor	Gemini CLI	Tabnine Agent
tabnine	Semantic code search across remote repos, coding guidelines	claude plugin install tabnine	Marketplace	gemini skills install	tabnine skills install
ctx	Query the Context Engine knowledge graph — investigate services, blast radius, Jira, incidents	claude plugin install ctx@tabnine	Marketplace	gemini skills install	tabnine skills install

Quick Start

Claude Code

# 1. Add the marketplace (one time)
claude plugin marketplace add tabnine/skills

# 2. Install plugins
claude plugin install tabnine       # codebase search + coding guidelines
claude plugin install ctx@tabnine   # Context Engine CLI

Cursor

Install via the Cursor plugin marketplace — both tabnine and ctx appear as separate plugins.

Manual install:

# Install Tabnine plugin into current project
bash <(curl -fsSL https://raw.githubusercontent.com/tabnine/skills/main/scripts/install-cursor-plugin.sh)

# Install globally
bash <(curl -fsSL https://raw.githubusercontent.com/tabnine/skills/main/scripts/install-cursor-plugin.sh) --global

Gemini CLI

Each skill is installed independently:

# Codebase search
gemini skills install https://github.com/tabnine/skills.git --path plugins/gemini/tabnine/codebase-search

# Coding guidelines
gemini skills install https://github.com/tabnine/skills.git --path plugins/gemini/tabnine/coding-guidelines

# Context Engine CLI
gemini skills install https://github.com/tabnine/skills.git --path plugins/gemini/ctx

Tabnine Agent

# Context Engine CLI
tabnine skills install https://github.com/tabnine/skills.git --path plugins/tabnine/ctx

# Codebase search
tabnine skills install https://github.com/tabnine/skills.git --path plugins/tabnine/codebase-search

# Coding guidelines
tabnine skills install https://github.com/tabnine/skills.git --path plugins/tabnine/coding-guidelines

Prerequisites

Tabnine plugin (codebase search + coding guidelines)

export TABNINE_HOST="your-tabnine-instance.tabnine.com"
export TABNINE_TOKEN="your-personal-access-token"

Obtaining a token: Open https://<TABNINE_HOST> > Settings > Access Tokens > Generate token.

ctx plugin (Context Engine CLI)

export CTX_API_URL="https://ctx.tabnine.com"
# Any of these work: CTX_API_KEY, TABNINE_TOKEN, or CTX_TOKEN
export CTX_API_KEY="ctx_..."

The ctx plugin also requires the ctx-cli binary. The skill teaches your agent how to download it, or install manually:

curl -fsSL https://github.com/tabnine/skills/releases/latest/download/ctx-cli-$(uname -s | tr A-Z a-z)-$(uname -m | sed 's/aarch64/arm64/') -o /usr/local/bin/ctx-cli && chmod +x /usr/local/bin/ctx-cli

Tabnine Plugin

Skills

Skill	Description
codebase-search	Search, explore, and investigate remote repositories using Tabnine's Context Engine
coding-guidelines	Fetch and apply team coding standards when reviewing or writing code

MCP Tools

All tools are served by the tabnine-context MCP server.

Tool	Description
remote_repositories_list	List all indexed repositories
remote_codebase_search	Semantic + lexical code search
remote_symbol_content	Find symbols with full source code
remote_symbols_search	Search for functions/classes/enums
remote_file_content	Fetch file contents from remote repos
remote_files_search	Search files by path/name
remote_repository_folder_tree	Browse repo directory structure
remote_search_assets	Search OpenAPI specs and service summaries
remote_openapi_spec_query	Query OpenAPI specs with jq expressions
remote_get_asset	Get full asset content
remote_grep_asset	Grep through asset content with regex

Investigator Agent

A read-only agent that performs deep investigation of remote repositories. It systematically explores code using all available MCP tools, follows references across repositories, and returns structured findings. Available in both Claude Code and Cursor.

/investigate How does the authentication flow work?

ctx Plugin

What it enables

The ctx skill teaches your agent to use the Context Engine CLI (ctx-cli) to query the knowledge graph. Examples:

# Investigate a service
ctx-cli mcp call investigate_service -p serviceName=auth-service -o json

# Check blast radius before making changes
ctx-cli mcp call blast_radius -p target=payment-api -p changeType=breaking -o json

# Search the knowledge graph
ctx-cli mcp call find_entities -p query="authentication" -o json

# Manage Jira issues
ctx-cli mcp call get_jira_issue -p issueKey=ENG-123 -o json

# Incident response
ctx-cli mcp call incident_response -p serviceName=auth-service -o json

# Discover all 100+ available tools
ctx-cli mcp list

How it works

The skill teaches the agent when and how to call ctx-cli. The CLI dynamically discovers tools from the Context Engine API — no hardcoded commands. The agent shells out to ctx-cli, parses JSON output, and presents results.

See the CLI spec for full design details.
