## What it does

The skill runs three sequential phases. First `scripts/enumerate.sh` walks the project and measures the codebase, then the agent reads sources and classifies entry points, and the last phase writes the report files into `x-ray/` at the project root. Progress goes through TodoWrite, with exactly one todo `in_progress` at any time.

A Python script, `scripts/analyze_git_security.py`, digs through repository history and writes `x-ray/git-security-analysis.json` with seven sections: repo shape, fix candidates, dangerous area changes, late changes, forked deps, tech debt and dev patterns. Two reference files, `references/threats.md` and `references/templates.md`, hold threat profiles and output templates and get preloaded before the report is written.

It targets Solidity projects: it looks for `.sol` files plus `foundry.toml` or `hardhat.config.*`, and checks one level deeper if neither turns up. Coverage comes from `forge coverage` or `npx hardhat coverage`. If `forge` is not installed the command fails, which is expected — enumeration already records whether tests exist. The skill also compares its local `VERSION` against the one in the repo via `curl` and warns when your copy is behind.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill x-ray -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill x-ray -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill x-ray -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pashov/skills x-ray
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill x-ray -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pashov/skills --path x-ray
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pashov/skills --skill x-ray -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/pashov/skills/tree/HEAD/x-ray/SKILL.md

## When to use it
- map every entry point in the contracts
- weigh risk from git history, not just current code
- collect protocol invariants before auditors start
- check whether docs and spec match the code
- surface tech debt and late changes before handoff

## Example prompts
- run x-ray on this protocol
- prep this protocol for an audit
- check audit readiness of the contracts in src/

# X-Ray

Generate an `x-ray/` folder at the project root containing all output files. Pipeline: 3 steps, always sequential.

`$SKILL_DIR` = the directory containing this SKILL.md file. Resolve it from the path you loaded this skill from (e.g. if this file is at `/path/to/x-ray/SKILL.md`, then `$SKILL_DIR` = `/path/to/x-ray`).

## Progress tracking (MANDATORY)

Before doing anything else, call TodoWrite with these 3 todos (all `pending`):

1. `Phase 1: Enumerate & measure codebase`
2. `Phase 2: Read sources, classify entry points, synthesize invariants`
3. `Phase 3: Write x-ray report files`

Transitions (update via TodoWrite — never batch):
- Mark Phase 1 `in_progress` immediately, before running `enumerate.sh`.
- When Step 1's parallel batch returns, in ONE TodoWrite call mark Phase 1 `completed` and Phase 2 `in_progress`.
- When Step 2 (including 2b–2g) finishes, in ONE TodoWrite call mark Phase 2 `completed` and Phase 3 `in_progress`.
- After all Step 3 output files are written, mark Phase 3 `completed`.

Rule: exactly one todo is `in_progress` at any time. Status updates happen the moment a phase starts or ends.

## Step 1: Enumerate & Measure

If the user specifies a path, use it as project root. Otherwise use cwd. If no `.sol` files or `foundry.toml`/`hardhat.config.*` at root, check one level deep.

**Source directory detection**: Auto-detect from `foundry.toml` (`src = "..."`) or `hardhat.config.*`. If no config, try both `src/` and `contracts/`. Read `foundry.toml` first if present.

**Run enumeration** (single Bash call — includes output directory creation):
```bash
mkdir -p [project-root]/x-ray && bash $SKILL_DIR/scripts/enumerate.sh [project-root] [src-dir]
```

**Immediately after**, launch ALL of the following in a single message (parallel):

**0. Version check** (foreground):
- Read the local `VERSION` file from `$SKILL_DIR/VERSION`
- Bash `curl -sf https://raw.githubusercontent.com/pashov/skills/main/x-ray/VERSION`
- If the remote VERSION fetch succeeds and differs from local, print `⚠️ You are not using the latest version. Please upgrade for best security coverage. See https://github.com/pashov/skills`. If it fails, skip silently.

**1. Coverage** (`run_in_background: true`):

For Foundry:
```bash
cd [project-root] && forge coverage 2>&1 || (echo "RETRYING_WITH_IR_MINIMUM" && forge coverage --ir-minimum 2>&1)
```

For Hardhat:
```bash
cd [project-root] && npx hardhat coverage 2>&1
```
