Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01378 | $0.01378 |
| Opus 5 | $0.00689 | $0.00689 |
| Sonnet 5 | $0.00276 | $0.00276 |
| Haiku 4.5 | $0.00138 | $0.00138 |
Grade A, and why
context-crystallizer CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview
Context Crystallizer is an AI Context Engineering tool that transforms large repositories into crystallized, AI-consumable knowledge through systematic analysis and optimization. It creates searchable knowledge bases that enable AI agents to work effectively with enterprise-scale projects by providing token-efficient, LLM-optimized context.
The system operates on the Model Context Protocol (MCP), providing tools for AI agents to crystallize repositories into structured, searchable context while maintaining a mirrored directory structure for intuitive navigation.
Development Commands
Build & Development
npm run build # Compile TypeScript to dist/
npm run dev # Development with hot reload using tsx
npm run dev:mcp # Development MCP server mode
npm run start # Run production build
npm run clean # Remove dist/ directory
Code Quality
npm run lint # ESLint check (.ts, .tsx files)
npm run typecheck # TypeScript type checking without emit
Application Modes
context-crystallizer # Start MCP server (default)
context-crystallizer <command> # CLI mode with specific commands
context-crystallizer version # Display version information
context-crystallizer init <repo-path> # Initialize crystallization
context-crystallizer search <query> # Search crystallized contexts
Core Architecture
Dual-Mode Entry Point
The application (src/index.ts) detects execution mode:
- No arguments: Starts MCP server for AI agent integration
- With arguments: Runs CLI commands for developer use
Core Components Architecture
CrystallizerCore (src/shared/crystallizer-core.ts)
- Central orchestration class that coordinates all crystallization operations
- Manages the lifecycle: initialization → file processing → context storage → search/retrieval
- Provides unified interface for both MCP tools and CLI commands
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

context-crystallizer CLAUDE.md is an instructions file published in the GitHub repository hubertciebiada/context-crystallizer (17 stars, last pushed 10mo ago), licensed MIT. It adds 1,378 tokens to every session, about $0.0069 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
