Q: How to install setup in Claude Code?

Run `npx skills add Necmttn/ax --skill setup -a claude-code`. The skill will be saved to `~/.claude/skills/setup/SKILL.md`.

Q: Does ax require a persistent background daemon?

No, ax maintains its graph in an embedded DuckDB file at `~/.local/share/ax/`. Commands update data on demand in the background, so no active service process needs to run.

Installs the ax environment, builds a local DuckDB session graph, and validates the agent configuration.

What setup does

The skill fetches install.sh into a temporary directory, presents it for review, and runs the script only after explicit confirmation. Next, it links axctl to ~/.local/bin/ax, adds ax skills to the coding agent, and executes ax ingest --since=7. That step ingests the last 7 days of agent transcripts into a local graph.

Storage runs on an embedded DuckDB file inside ~/.local/share/ax/. No background daemon stays in memory. Cache queries automatically trigger a background refresh when stale. The skill then runs ax doctor --json to verify the setup and prompts you to categorize untagged tools with ax skills classify. If $HOME/.local/bin is missing from PATH, shell sessions will fail to locate ax.

What it helps with

install the ax CLI and related agent skills
verify environment health using ax doctor
seed the DuckDB session graph with 7 days of history
assign functional roles to unclassified skills
review model spending breakdown across runs

Example prompts for the agent

Install and set up ax in Claude Code
ax not found, fix the installation
Run ax doctor to check the system
