AI Documentation CLI — fetch latest API documentation for open source tools.
Designed for AI coding assistants (Claude Code, GitHub Copilot) to get up-to-date API references for libraries like Apache Kafka, Redis, ClickHouse, Java SE, Google Guava, and more — instead of relying on potentially stale training data.
Inspired by @aisuite/chub.

Copy the skill definition to your Claude skills directory:
mkdir -p ~/.claude/skills/get-api-docs
cp $(npm root -g)/@diepdao/aicli/skills/get-api-docs/SKILL.md ~/.claude/skills/get-api-docs/SKILL.mdOr reference skills/get-api-docs/SKILL.md in your Copilot/Claude instructions.
The skill file teaches the AI assistant to use aicli to fetch current docs before answering API questions.
# Clone and install
git clone https://github.com/diepdaocs/aicli
cd aicli
npm install
# Build
npm run build
# Test locally
npm link
aicli search kafka
# Unlink when done
npm unlink -g @diepdao/aicliEdit src/lib/registry.ts and add a new entry to the REGISTRY array:
