agentscaffold 0.2.0

Structured AI-assisted development framework with plan lifecycle, review gates, and continuous improvement.

AgentScaffold

Stop paying for your AI agent to rediscover your codebase every session.

AgentScaffold is a governance framework and persistent knowledge graph for AI coding agents. It replaces the expensive pattern of agents reading dozens of files, grepping for symbols, and tracing dependencies from scratch -- with a single tool call that returns exactly what the agent needs.

The Problem

Every time you start a new session with Cursor, Claude Code, Codex, or any AI coding agent, it starts from zero. It reads your files. It greps for imports. It traces call chains. It burns through your token budget and subscription quota just to understand what it already understood yesterday.

On a moderately complex codebase, a single "understand this module" task can cost 12 file reads + 2 grep searches before the agent even starts working. A full plan review pulls in 10+ files. Getting oriented in a new codebase means reading 38+ files.

This is the hidden cost of agentic development: not the coding, but the context building.

The Solution

AgentScaffold builds a knowledge graph of your codebase -- code structure, dependencies, governance artifacts, session history -- and exposes it through MCP tools that your agent calls instead of reading raw files.

Measured results from our evaluation harness (64 scenarios, 100% pass rate):

Task	Without AgentScaffold	With AgentScaffold	Savings
Understand a module and its dependents	12 reads + 2 greps	1 tool call	97% fewer tokens, 93% fewer calls
Codebase orientation	38 file reads	2 tool calls	77% fewer tokens, 95% fewer calls
Impact analysis (blast radius)	12 file reads	1 tool call	88% fewer tokens, 92% fewer calls
Find all code matching a concept	8 file reads	1 tool call	44% fewer tokens, 88% fewer calls
Full plan review with evidence	10 file reads	1 tool call	90% fewer calls (richer output)

Aggregate: 91% average call reduction. 58% average token reduction. 2.9x overall compression.

Every tool call your agent doesn't make is money you don't spend on API tokens or subscription overages.

What It Does

AgentScaffold combines two capabilities that don't exist together in any other tool:

1. Agent Governance Framework

A structured development workflow that teaches your AI agent to follow a plan lifecycle with quality gates:

• Plan lifecycle: Draft -> Review -> Ready -> In Progress -> Complete
• Adversarial reviews: Devil's advocate, expansion analysis, domain-specific reviews -- all run before a single line of code is written
• Interface contracts: Formal declarations of module boundaries, versioned and tracked
• Retrospectives: Post-execution learning that feeds back into the process
• Session tracking: State files that persist context across chat sessions

2. Persistent Knowledge Graph

A KuzuDB-backed graph that indexes your codebase once and serves it to agents instantly:

• Code structure: Functions, classes, methods, interfaces, import chains, call graphs -- across Python, TypeScript, Go, Rust, Java, C, and C++
• Governance artifacts: Plans, contracts, learnings, review findings linked to the code they reference
• Community detection: Leiden algorithm clustering identifies tightly coupled modules
• Semantic search: Hybrid search combining structural graph queries with vector embeddings
• Incremental indexing: SHA-256 content hashing means only changed files are re-processed
• Contract drift detection: Automatically surfaces methods declared in contracts but missing from code

The graph is exposed via MCP tools that any compatible agent can call, or through the CLI for direct use.

Quick Start

pip install agentscaffold
cd my-project
scaffold init
scaffold index          # Build the knowledge graph

The init command scaffolds your project with:

• docs/ai/ -- templates, prompts, standards, state files
• AGENTS.md -- rules your AI agent follows automatically
• .cursor/rules.md -- Cursor-specific rules
• scaffold.yaml -- your project's framework configuration
• justfile + Makefile -- task runner shortcuts
• .github/workflows/ -- CI with security scanning

The index command builds the knowledge graph at .scaffold/graph.db, enabling search, reviews, impact analysis, and session memory.

Install with language support

pip install agentscaffold[graph]              # Python, JS, TS
pip install agentscaffold[graph-all-languages] # + Go, Rust, Java, C, C++
pip install agentscaffold[all]                # Everything

How Agents Use It

MCP Tools (for AI agents)

When you run scaffold mcp, these tools become available to your agent:

Tool	What It Replaces
scaffold_context	Reading 12+ files to understand a symbol, its callers, and its layer
scaffold_impact	Manually tracing imports and grep-searching for consumers
scaffold_search	Multiple grep passes to find code by concept
scaffold_review_context	Reading plan files, contracts, learnings, and source to prepare a review
scaffold_stats	Scanning the entire directory tree to understand codebase shape
scaffold_validate	Running separate staleness checks and contract verification
scaffold_query	Writing ad-hoc Cypher queries against the knowledge graph

CLI (for humans)

scaffold plan create my-feature        # Create a plan from template
scaffold plan lint --plan 001          # Validate plan structure
scaffold plan status                   # Dashboard of all plans
scaffold validate                      # Run all enforcement checks
scaffold retro check                   # Find missing retrospectives
scaffold agents generate               # Regenerate AGENTS.md
scaffold agents cursor                 # Regenerate .cursor/rules.md
scaffold import chat.json --format chatgpt  # Import conversation
scaffold ci setup                      # Generate CI workflows
scaffold metrics                       # Plan analytics
scaffold graph search "data routing"   # Hybrid search
scaffold graph verify                  # Graph accuracy check
scaffold review brief 42               # Pre-review brief for plan 42
scaffold review challenges 42          # Adversarial challenges with evidence
scaffold session start --plan 42       # Start a tracked coding session

Execution Profiles

Interactive (default): Human + AI agent in an IDE conversation. The agent follows AGENTS.md, asks questions when uncertain.

Semi-Autonomous (opt-in): Agent invoked from CLI/CI without a human present. Adds session tracking, safety boundaries, notification hooks, structured PR output, and cautious execution rules.

Both profiles coexist in the same AGENTS.md. The agent self-selects based on invocation context.

Rigor Levels

• Minimal: Lightweight gates for prototypes and small projects
• Standard: Full plan lifecycle with reviews, contracts, and retrospectives
• Strict: All gates enforced, all plans require approval

Domain Packs

Domain packs add specialized review prompts, standards, and approval gates:

Pack	Focus

webapp	UX/UI, accessibility, performance budgets
mlops	Model lifecycle, experiment tracking, drift detection
data-engineering	Pipeline quality, schema evolution, SLAs
