claude-atlas 0.3.1

Scan, map, and visualize your Claude Code setup: agents, skills, slash commands, and memory files.

🗺️ Claude Atlas

Audit your Claude Code setup. Find duplicate agents, conflicting triggers, and orphaned memory files before they silently break your workflow.

Languages: English · Português 🇧🇷

---

If you've been building out ~/.claude/ for a while, you probably have:

• Two agents that do nearly the same thing, competing for the same triggers.
• A CLAUDE.md you wrote for a project you abandoned months ago.
• A global skill quietly shadowed by a project-scoped version in one of your repos.
• No clear picture of how many artifacts you've accumulated total.

Claude Atlas scans your setup and surfaces these in seconds. Run it in your terminal for a quick health check, or generate an interactive HTML report for deeper triage.

# Install
uv tool install claude-atlas

# 5-second health check
claude-atlas check

# Full interactive report
claude-atlas scan

Offline by default. MIT licensed. Docs in EN + PT-BR.

Install

Prerequisites: Python 3.11+ and uv (or pipx / pip).

If you don't have uv yet:

# macOS (Homebrew)
brew install uv

# macOS / Linux (official installer)
curl -LsSf https://astral.sh/uv/install.sh | sh

Then install claude-atlas:

# Recommended: isolated tool install (from PyPI)
uv tool install claude-atlas

# Or with pipx
pipx install claude-atlas

# Or plain pip
pip install claude-atlas

To upgrade: uv tool upgrade claude-atlas.

From source

git clone https://github.com/grippado/claude-atlas.git
cd claude-atlas
uv sync --all-extras
uv run claude-atlas --help

Quick start

# Scan ~/.claude + current dir, output to ./claude-atlas.html
claude-atlas scan

# Scan specific trees
claude-atlas scan --paths ~/work/arco --paths ~/work/flagbridge -o /tmp/atlas.html

# Auto-discover nested .claude/ dirs under several trees
claude-atlas scan --auto-discover ~/work --auto-discover ~/personal

# Refine duplicate candidates with Claude (needs ANTHROPIC_API_KEY)
claude-atlas scan --semantic

Open the resulting HTML in a browser. Click nodes to inspect, switch to the Issues tab to see what needs attention.

What it detects

Edge kind	Meaning
duplicate_exact	Identical SHA-256 body hash — one is a literal copy of the other.
duplicate_semantic	Jaccard similarity ≥ 0.60 (suspicious) / ≥ 0.85 (probable).
overrides	Project artifact shadows a same-named global one.
trigger_collision	Two artifacts share ≥ 2 distinctive trigger tokens.
references	One artifact's body mentions another's name.
contains	Memory file groups artifacts in the same .claude/ root (UI only).

Thresholds live in src/claude_atlas/analysis/graph.py if you want to tune them.

Optional: LLM-as-judge

With --semantic, pairs flagged by Jaccard are sent to the Anthropic API for a structured verdict (duplicate / overlap / distinct). Pairs the model calls "distinct" are dropped from the graph; the rest get the model's reasoning attached to the edge detail.

Requires ANTHROPIC_API_KEY. Reinstall with the semantic extra to pull the anthropic SDK:

uv tool install "claude-atlas[semantic]"

Commands

claude-atlas scan        full scan + report
claude-atlas report      alias for scan with default flags
claude-atlas version     print version

Run any command with --help for full flags.

CI / pre-commit usage

Use claude-atlas check for lint-style health checks in scripts and CI:

# Default: fail on any HIGH-severity issue
claude-atlas check

# Pre-commit hook: only fail on duplicates and overrides
claude-atlas check --max-severity high --quiet

# CI with GitHub Actions annotations
claude-atlas check --format github

# Get everything as JSON for custom tooling
claude-atlas check --top 0 --format json

Exit codes: 0 (clean), 1 (issues found at threshold), 2 (error).

Roadmap

Claude-atlas is in active evolution. See the full ROADMAP.md for principles, released versions, and what's planned.

Next up: v0.4.0 — HTML triage dashboard. The graph view becomes a secondary tab; the primary view becomes a card-based triage dashboard with health score, side-by-side previews, and per-issue actions. Follow progress in #1.

Considering: interactive fix-prompt export (claude-atlas fix), scan history diffing, pre-commit hook templates, editor status-bar plugin.

Won't do: automatic editing/deletion of artifacts, cloud sync, accounts, or support for non-Claude-Code AI tools. See the anti-roadmap for why.
