Cheat Sheet

All 13 skills trigger automatically from natural language — just describe what you need:

Input	What Happens
"what can attune do?"	Auto-triggers attune-hub — guided discovery
"build this feature from scratch"	Auto-triggers spec — brainstorm → plan → execute
"review my code"	Auto-triggers code-quality skill
"scan for vulnerabilities"	Auto-triggers security-audit skill
"generate tests for src/"	Auto-triggers smart-test skill
"fix failing tests"	Auto-triggers fix-test skill
"predict bugs"	Auto-triggers bug-predict skill
"generate docs"	Auto-triggers doc-gen skill
"plan this feature"	Auto-triggers planning skill
"refactor this module"	Auto-triggers refactor-plan skill
"prepare a release"	Auto-triggers release-prep skill
"run all workflows"	Auto-triggers workflow-orchestration skill

Skills run using your Claude subscription — no API key needed.

What the Output Looks Like

$ attune workflow run security-audit --path src/

Looking solid — this is in great shape.

## Findings
Score: 95/100
3 issues found (1 medium, 2 low)

  Cost & Time
  $0.03 (saved 58% vs premium) | 12.4s

  What I'd Do Next
  I'd run `attune workflow run bug-predict` next —
  your spec has work remaining.

Every workflow speaks in the same voice, with contextual next-step suggestions based on what just happened and what your spec says should come next.

v5.0.0 aligned all 15 SDK-native workflows with Anthropic's recommended patterns for the Claude Agent SDK. This is the foundation everything else builds on.

Feature	What It Does
System prompt separation	Each workflow splits persona from task instructions, passed via system_prompt= on ClaudeAgentOptions
Per-agent model routing	Security/architect to Opus, quality/planning to Sonnet, lint/coverage to Haiku. Override with env vars
Budget safety nets	$0.50 quick / $2.00 standard / $5.00 deep — configurable per workflow, override with ATTUNE_MAX_BUDGET_USD
Cost and usage tracking	AgentRunResult captures actual cost, token counts, duration, and session ID from every run
Structured output	JSON schema output for code-review and security-audit with confidence scores and findings
26 new SDK tests	Budget caps, model routing, cost extraction, structured output adapter

v5.0.1 — v5.0.2 patch notes

v5.0.2 — Fixed all 15 Agent SDK workflows. Added collect_agent_output() to collect from both ResultMessage and AssistantMessage content blocks.

How to Access Workflows

There are three ways to run workflows, depending on your context:

How	When to Use	Example
Natural language	In Claude Code (recommended)	"scan this for security issues"
attune-hub skill	When you're not sure which workflow	"what can attune do?"
CLI	Terminal, CI/CD, automation	attune workflow run security-audit --path src/

Skills use your Claude subscription. CLI mode requires ANTHROPIC_API_KEY.

Install

claude plugin marketplace add Smart-AI-Memory/attune-ai
claude plugin install attune-ai@attune-ai

Update an existing install:

claude plugin update attune-ai

Workflows

Every workflow runs as a multi-agent team. Each agent is a specialist — it reads your code with Read, Glob, and Grep tools and reports findings to an orchestrator that synthesizes a unified result.

Workflow	Agents	What It Does	When to Use
code-review	security-reviewer, quality-reviewer, perf-reviewer, architect-reviewer	4-perspective code review covering security, quality, performance, and architecture	Before merging a PR or after significant changes
security-audit	vuln-scanner, secret-detector, auth-reviewer, remediation-planner	Finds vulnerabilities, leaked secrets, auth issues, and generates fix plans	Pre-release security gate, compliance checks
deep-review	security-reviewer, quality-reviewer, test-gap-reviewer	Multi-pass deep analysis with configurable focus areas	Complex modules needing thorough inspection
perf-audit	complexity-analyzer, bottleneck-finder, optimization-advisor	Identifies O(n^2) patterns, bottlenecks, and optimization opportunities	Slow endpoints, large data processing
bug-predict	pattern-scanner, risk-correlator, prevention-advisor	Scans for bug-prone patterns and predicts likely failure points	Proactive quality — find bugs before users do
health-check	test-checker, dep-checker, lint-checker, ci-checker, doc-checker, security-checker	Dynamic agent team (2-6 agents based on mode) for project health	Daily health monitoring, onboarding to a new repo
test-gen	function-identifier, test-designer, test-writer	Identifies untested functions, designs test cases, writes pytest code	Boosting coverage on undertested modules
test-audit	coverage-auditor, gap-analyzer, test-planner	Audits test coverage, finds gaps, and prioritizes what to test next	Coverage-driven test improvement
doc-gen	outline-planner, content-writer, polish-reviewer	Generates documentation from source code with structured outlines	Creating docs for undocumented modules
doc-audit	staleness-checker, accuracy-reviewer, gap-finder	Checks for stale docs, broken links, and documentation drift	Keeping docs accurate after refactors
dependency-check	inventory-assessor, update-advisor	Audits dependencies for outdated packages and security advisories	Pre-release dependency review
refactor-plan	debt-scanner, impact-analyzer, plan-generator	Scans tech debt, analyzes refactoring impact, generates migration plans	Planning large-scale refactors
simplify-code	complexity-scanner, simplification-designer, safety-reviewer	Finds over-engineered code and proposes simplifications with safety review	Reducing complexity after feature sprints
release-prep	health-checker, security-scanner, changelog-generator, release-assessor	4-agent readiness check: health, security, changelog, and go/no-go	Before cutting a release
doc-orchestrator	inventory-scanner, outline-planner, content-writer, polish-reviewer	End-to-end documentation orchestration across an entire project	Full-project doc generation or refresh
orchestrated-health-check	dynamic team (2-6 based on mode)	Extended health check with dynamic agent team and severity scoring	Comprehensive project health assessment
secure-release	security-scanner, health-checker, dep-auditor, release-gater	Go/no-go release pipeline with combined risk scoring and blocker detection	Pre-publish security gate
research-synthesis	source-summarizer, pattern-analyst, synthesis-writer	Multi-source research synthesis with pattern extraction	Technical research, RFC preparation

Model Routing

Each agent is assigned a model based on task complexity:

Model	Agents	Rationale
Opus	security, vuln, architect	Deep reasoning for security and architecture
Sonnet	quality, plan, research	Balanced analysis for synthesis and planning
Haiku	complexity, lint, coverage, dep	Fast scanning for detection tasks
Inherited	All others	Uses the parent orchestrator's model

Override any assignment with environment variables:

export ATTUNE_AGENT_MODEL_SECURITY=sonnet  # Save cost
export ATTUNE_AGENT_MODEL_DEFAULT=opus     # Max quality

Budget Controls

Every workflow enforces a budget cap based on depth:

Depth	Budget	Use Case
quick	$0.50	Fast checks, smoke tests
standard	$2.00	Normal analysis (default)
deep	$5.00	Thorough multi-pass review

export ATTUNE_MAX_BUDGET_USD=10.0  # Override
export ATTUNE_MAX_BUDGET_USD=0     # Disable caps

Quick Start

Option A: Plugin Only (zero-config)

claude plugin marketplace add Smart-AI-Memory/attune-ai
claude plugin install attune-ai@attune-ai

Then in Claude Code, just say what you need:

• "review my code" — triggers code-quality skill
• "scan for security issues" — triggers security-audit
• "what can attune do?" — triggers attune-hub discovery
• "build this from a spec" — triggers spec-driven dev

Option B: Plugin + Python Package (full power)

claude plugin marketplace add Smart-AI-Memory/attune-ai
claude plugin install attune-ai@attune-ai
pip install 'attune-ai[developer]'

attune doctor    # Verify environment
attune auth      # Configure API key or subscription
