# axiom-tools

A router skill for the Axiom suite: points you to the right tool for builds, console output, crash symbolication and CPU profiles. Handy on iOS/Swift work in an agent.

## What it does

axiom-tools is the entry point to the Axiom set. It does not build or parse anything itself — it routes a question to the right reference: `axbuild` for build and test capture, `xclog` for console output, `xcsym` for symbolication of `.ips`, MetricKit and `.crash` files, `xcui` for simulator UI and accessibility checks, `xcprof` for `xctrace` and CPU profiles. A separate branch covers driving a simulator or device with no Xcode running, including screenshots, video capture and cleaning up the status bar for App Store shots.

Inside is a routing table: question on the left, reference file on the right. There is also a section on how to use Axiom skills — check the matching skill before answering anything iOS/Swift, do not skip the routers, and pull in several when a question spans domains. For Codex the auditors are rewritten as skills, so you invoke the matching skill instead of launching an agent. Several of them — builds, tests, simulators, symbolication — need shell access to run.

On Claude the tools ship inside the plugin. If `command -v <tool>` finds nothing — hooks are off or you launched with `--bare` — use `<plugin-root>/tools/<tool>`, where `<plugin-root>` sits two levels above the `Base directory for this skill:` path. That is the first thing to check when a tool looks missing but the plugin is installed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add CharlesWiltgen/Axiom --skill axiom-tools -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/axiom-tools/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/axiom-tools/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add CharlesWiltgen/Axiom --skill axiom-tools -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/axiom-tools/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add CharlesWiltgen/Axiom --skill axiom-tools -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/axiom-tools/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install CharlesWiltgen/Axiom axiom-tools
```

2. **Manually: put the files in place**
- File: `.github/skills/axiom-tools/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add CharlesWiltgen/Axiom --skill axiom-tools -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/CharlesWiltgen/Axiom --path axiom-codex/skills/axiom-tools
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/axiom-tools/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add CharlesWiltgen/Axiom --skill axiom-tools -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/CharlesWiltgen/Axiom/tree/HEAD/axiom-codex/skills/axiom-tools/SKILL.md

## When to use it
- capture console output from a simulator
- symbolicate an unsymbolicated `.ips` or MetricKit crash
- script simulator UI and accessibility checks
- analyze a CPU profile from `xctrace`
- drive a simulator or device without Xcode running

## Example prompts
- How do I capture console output from the simulator?
- Why is my crash unsymbolicated, and how do I use xcsym?
- How do I analyze a CPU profile with xcprof?

# Axiom Tools & Onboarding

This suite covers Axiom itself — how to use it, what's available, and the tools that ship with it.

**Bundled tools on Claude Code:** if `command -v <tool>` finds nothing (hooks off or `--bare`), use `<plugin-root>/tools/<tool>` in place of the bare name; `<plugin-root>` is two levels above this skill's `Base directory for this skill:` path.

<!-- AXIOM_AUDITOR_INLINE_BEGIN — rewritten for Codex by scripts/build-codex.ts; do not hand-edit -->
> **Auditors are skills here.** Where this router says "Launch `some-auditor` agent", invoke the
> matching Codex skill instead — same procedure, no Claude Code agent required.
>
> Available: `axiom-analyze-test-failures`, `axiom-audit-accessibility`, `axiom-audit-concurrency`, `axiom-audit-energy`, `axiom-audit-memory`.
>
> The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
<!-- AXIOM_AUDITOR_INLINE_END -->

## Build and Test Capture

For axbuild installation, report handling and saved-log fallback, read `axiom-build` before a build or test.
