squadron-ai 0.3.9

Multi-agent squadron framework

Squadron

Repeatable, template-driven code reviews powered by Claude — from the terminal.

Point sq at a diff, an architecture doc, or a task plan and get back a structured verdict with specific findings. No more freeform "hey Claude, review this" — each review runs against a purpose-built prompt template that tells the agent exactly what to evaluate and how to report what it finds.

sq review slice 120 -v

Why this exists

Code review with LLMs is powerful but inconsistent. The same prompt gets different levels of scrutiny depending on how you phrase it, what context you include, and whether you remembered to mention your project's conventions.

Squadron makes reviews repeatable. A review template defines the system prompt, the tools the agent can use, and the inputs it expects. Run the same template on Monday and Friday and you get structurally consistent output — a verdict (PASS, CONCERNS, or FAIL) and a list of findings with severity levels.

Three built-in templates cover the most common review patterns:

Template	What it reviews
slice	A design document against an architecture reference
tasks	A task breakdown against its parent slice design
code	Source code, optionally scoped to a diff or glob

The template system is extensible — each template is a YAML file, and adding new review types means writing a new YAML definition and optionally a prompt builder function. See docs/TEMPLATES.md for details.

Install

Global install (recommended)

# Using pipx (recommended)
pipx install squadron-ai

# Or using uv
uv tool install squadron-ai

After install, sq is available on PATH:

sq --version
sq install-commands   # Install Claude Code slash commands

Development install

git clone https://github.com/manta/squadron.git
cd squadron
uv sync --dev

Pre-commit hook (recommended)

A self-healing pre-commit hook auto-formats code and fixes import order before every commit, keeping CI green:

cat > .git/hooks/pre-commit << 'EOF'
#!/bin/sh
uv run ruff format .
uv run ruff check --fix --exit-zero .
git add -u
EOF
chmod +x .git/hooks/pre-commit

Note: .git/hooks/ is not tracked by git. Run the above after every fresh clone or worktree creation.

Quickstart

1. Configure credentials

Squadron uses the Claude Agent SDK, which supports two authentication methods:

Claude Max subscription (recommended): If you're already signed into Claude Code, you're set — the SDK uses your existing session. No API key needed.

# Verify you're authenticated
claude --version

API key: Alternatively, set an Anthropic API key:

export ANTHROPIC_API_KEY="sk-ant-..."

2. Review a design before writing code

Everyone reviews code. Almost nobody reviews the spec before writing the code. Start there:

# Does this slice design align with the architecture?
sq review slice 120 -v

The CLI resolves file paths automatically when you pass a slice number (requires Context Forge). Or pass paths directly:

sq review slice design.md --against architecture.md -v

You should see Rich-formatted output with a verdict and findings within about 30 seconds.

3. Review the task breakdown, then the code

# Does this task plan cover everything in the design?
sq review tasks 118 -v

# Review code changes
sq review code --diff main -v

Using different models

Use --model with a built-in alias to run reviews through any supported provider:

# Claude (default — uses SDK)
sq review slice 120 -v

# OpenAI
sq review code --diff main --model gpt54-nano -v

# Google Gemini
sq review slice 120 --model flash3 -v

# OpenRouter
sq review tasks 118 --model kimi25 -v

Non-SDK models automatically get file contents and diffs injected into the prompt, so they can review actual code without tool access.

Run sq models to see all available aliases:

Add your own aliases in ~/.config/squadron/models.toml:

[aliases]
deepseek = { profile = "openrouter", model = "deepseek/deepseek-r2" }

Using Codex (experimental)

The codex-agent alias enables OpenAI Codex agentic mode for reviews and agent tasks. Codex provides sandbox file access, command execution, and subscription-based authentication:

sq review slice 120 --model codex-agent -v

Setup: Codex support requires two additional components:

1. Codex CLI (via npm):

   npm i -g @openai/codex
   

2. Codex Python SDK (from GitHub):

   pip install 'codex-app-server-sdk @ git+https://github.com/openai/codex.git#subdirectory=sdk/python'
   

3. Authenticate via OpenAI API key:

   # Option A: Set environment variable
   export OPENAI_API_KEY="sk-..."
   
   # Option B: Use Codex CLI (saves to ~/.codex/auth.json)
   codex auth login
   

Codex is experimental and requires active OpenAI subscriptions. The standard codex alias (without -agent suffix) uses OpenAI's Chat Completions API and doesn't require this setup.

Reviews in depth

Scoping code reviews

Code reviews can be scoped by diff, file pattern, or both:

# Everything in the project
sq review code

# Only changes since main
sq review code --diff main

# Only Python files
sq review code --files "src/**/*.py"

# Changes to Python files since main
sq review code --diff main --files "src/**/*.py"

Adding project-specific rules

Point reviews at a rules file to include project conventions in the agent's system prompt:

sq review code --diff main --rules ./rules/python.md

Your project's CLAUDE.md is loaded automatically via the SDK's setting_sources mechanism — the --rules flag is for additional guidance on top of that.

Verbosity

Default output is compact — just the verdict and finding headings. Turn up verbosity when you want details:

Flag	Shows
(default)	Verdict + finding headings
-v	Above + full finding descriptions
-vv	Above + raw agent tool usage

Output formats

# Rich terminal output (default)
sq review code --diff main

# JSON to stdout (for piping / scripting)
sq review code --diff main --output json

# JSON to file
sq review code --diff main --output file --output-path result.json

Configuration

Avoid repeating flags with persistent config. Two levels with clear precedence:

# Set your default working directory (user-level)
sq config set cwd ~/projects/myapp

# Set project-specific rules (project-level)
sq config set default_rules ./rules/python.md --project

# Check where a value is coming from
sq config get cwd

# See everything
sq config list

Precedence (highest wins): CLI flag → project config (.squadron.toml) → user config (~/.config/squadron/config.toml) → built-in default.

Available keys: cwd, verbosity, default_rules, compact.template, compact.instructions. See docs/COMMANDS.md for full details.

Interactive /compact for Claude Code

Squadron ships a PreCompact hook that runs whenever you type /compact (or auto-compaction fires) inside an interactive Claude Code session — VS Code extension or CLI Claude Code. The hook feeds project-aware instructions into Claude Code's compaction summarizer so slice context isn't lost.

sq install-commands writes the hook entry into your project's .claude/settings.json alongside the slash command files:

sq install-commands   # installs slash commands AND the PreCompact hook

Pick the instructions the hook emits with either of two config keys:

# Named template (resolved from ~/.config/squadron/compaction/ then built-ins)
sq config set compact.template minimal --project

# Or a literal string — wins over compact.template if both are set.
# Params {slice}, {phase}, and {project} are substituted from Context Forge.
sq config set compact.instructions "Keep slice {slice} design and tasks only." --project

Both keys honour the usual --project / user layering. sq uninstall-commands removes the squadron-managed hook entry while preserving any third-party hooks.

Agent management

Squadron also exposes lower-level agent lifecycle commands. These are the building blocks for the review system and are available for direct use:

sq spawn --name my-agent
sq task my-agent "Analyze the error handling in src/core/"
sq list
sq shutdown my-agent

Exit codes

Code	Meaning
0	Success (PASS or CONCERNS verdict)
1	Error (invalid arguments, missing files, runtime error)
2	Review verdict is FAIL

CONCERNS returns exit code 0 — it's informational, not a failure. This makes sq usable in CI pipelines where you want to gate on FAIL but not on warnings.

Pipelines (sq run)

Pipelines compose multi-step AI workflows into a single repeatable command:

sq run slice 152          # design → tasks → implement → devlog for slice 152
sq run --list             # show all available pipelines

When running inside Claude Code (VS Code or terminal), use --prompt-only to get step-by-step instructions instead of direct LLM dispatch — or install the /sq:run slash command which wraps this automatically:

sq install-commands       # installs /sq:run and other slash commands

See docs/PIPELINES.md for the full authoring guide: YAML grammar, step types, model resolution, and how to write custom pipelines.
