Brewtools:Text Optimize

Text & File Optimizer

Step 0: Load Rules

REQUIRED: Read references/rules-review.md before ANY optimization.

If file not found -> ERROR + STOP. Do not proceed without rules reference.

Modes

Parse $ARGUMENTS: -l/--light | -s/--standard | -d/--deep | no flag -> medium (default) or auto-detect.

Smart Auto-Detection

When no flag provided AND input suggests compression (not just optimization):

1. Parse file path + content header 2. Classify:

• LLM-only files (CLAUDE.md, .claude/rules/*.md, .claude/agents/*.md, .claude/skills/**/SKILL.md, KNOWLEDGE.*, system prompts) → deep candidate
• README.md, docs/, API references, user-facing docs → standard candidate
• Unknown / mixed → ask user via AskUserQuestion

3. If confident → tell user: "Selected mode: {mode} for {file} because {reason}" 4. If ambiguous → AskUserQuestion with mode options 5. User can override via flags regardless of auto-detection

2-Phase Execution

Orchestration: Phase 1+2 are executed by the SKILL in the main conversation (manager level). The text-optimizer agent handles single-file optimization only — it cannot spawn sub-agents.

Phase 1: Analysis — Parallel Explore agents

Task(subagent_type: "Explore", prompt: "Analyze {file}: structure, dependencies, cross-refs, redundancies")

Phase 2: Optimization — Parallel text-optimizer agents

Context: BT_PLUGIN_ROOT is available in your context (injected by pre-task.mjs hook). Use it to access plugin resources.

Task(subagent_type: "text-optimizer", prompt: "FIRST: Read $BT_PLUGIN_ROOT/skills/text-optimize/references/rules-review.md for validation rules. FOR STANDARD MODE: Also read $BT_PLUGIN_ROOT/skills/text-optimize/references/standard-compression.md. FOR DEEP MODE: Also read $BT_PLUGIN_ROOT/skills/text-optimize/references/deep-compression.md. THEN optimize {file} using {mode} mode. Apply transformations, verify refs, output report with metrics.")

Spawn parallel: For multiple files, spawn ALL agents in ONE message for speed.

Quality Checklist

Before

• [ ] Read entire text
• [ ] Identify type (prompt, docs, agent, skill)
• [ ] Note critical info and cross-references

During — Apply by Mode

Deep Mode Pipeline

Phase 1: Compress

• Load references/deep-compression.md for symbol/abbreviation tables
• Scan text for terms occurring 3+ times → build DICT header
• Apply symbol substitutions, filler removal, structural compression
• Apply existing rules (C, T, S, R, P) in addition to deep techniques

Phase 2: Verify Round 1

• Spawn verification agent with ORIGINAL + COMPRESSED text
• Agent reads both, lists all lost/distorted facts
• Calculate semantic match %
• If >= 95% → done
• If < 95% → return loss list for patching

Phase 3: Patch + Verify Round 2

• Apply patches for missing facts
• Re-verify
• If still < 95% → warn user with loss list
• Output final result + statistics

Standard Mode Pipeline

Phase 1: Compress

• Load references/standard-compression.md
• Remove filler words/constructions
• Merge repeated ideas
• Convert paragraphs to bullets/tables where appropriate
• Apply existing rules (C, T, S, R, P)

Phase 2: Verify

• Compare compressed vs original
• List any lost facts → patch
• One round only

Iron Rules (All Modes)

After

Anti-Patterns

Text Optimizer

Optimizes text files for LLM token efficiency with 4 compression modes — from light cleanup to deep dictionary-encoded compression for LLM-only documents. Applies 40+ validated rules for Claude 4.x, supports smart auto-detection of optimal mode, and verifies no information loss. Works on single files, multiple files in parallel, or entire directories.

Quick Start

/brewtools:text-optimize CLAUDE.md

Auto-detects optimal mode for the file (deep for CLAUDE.md, standard for README.md), applies all standard transformations, and prints a report with token savings.

Modes

Examples

Good Usage

# Single file, medium mode (default)
/brewtools:text-optimize CLAUDE.md

# Light mode on a production agent -- safe, minimal changes
/brewtools:text-optimize -l .claude/agents/reviewer.md

# Deep mode on a verbose prompt you want compressed
/brewtools:text-optimize -d prompts/analysis-prompt.md

# Multiple files processed in parallel
/brewtools:text-optimize agents/planner.md, agents/executor.md, CLAUDE.md

# All markdown files in a directory
/brewtools:text-optimize -d agents/

# Standard mode — 30-50% compression, stays human-readable
/brewtools:text-optimize -s docs/getting-started.md

# Deep mode — max compression with dictionary encoding for LLM consumption
/brewtools:text-optimize -d CLAUDE.md

# Auto-detect: CLAUDE.md → deep, README.md → standard
/brewtools:text-optimize CLAUDE.md
/brewtools:text-optimize README.md

# Prompt hint overrides auto-detect
/brewtools:text-optimize "super compress" verbose-doc.md

Common Mistakes

# Running deep mode on production files without reviewing the diff
/brewtools:text-optimize -d CLAUDE.md
# Deep mode aggressively rephrases and merges sections.
# ALWAYS review the diff before accepting deep mode changes.

# Optimizing generated or third-party files you don't control
/brewtools:text-optimize node_modules/some-lib/README.md
# Only optimize files YOU maintain. External files get overwritten on update.

# Using deep mode on files with precise technical references
/brewtools:text-optimize -d API-REFERENCE.md
# Deep mode may rephrase domain terms or merge sections that need to stay separate.
# Use light (-l) or medium for reference documentation.

# Using deep mode on user-facing documentation
/brewtools:text-optimize -d README.md
# Deep mode uses dictionary encoding and symbols not readable by humans.
# Use standard (-s) for docs that humans will read.

# Expecting deep mode output to be human-readable
# Deep mode is designed for LLM consumption only (CLAUDE.md, system prompts).
# The output uses DICT headers, symbols (→, !=, ∵), and abbreviations.

Auto-Detection

When no mode flag is provided, the optimizer analyzes the file path and content to select the best mode:

Prompt text can also hint at the mode: "compress for LLM" → deep, "safe compress" → standard, "super compress" → deep.

Verification

Standard and deep modes include automatic verification to prevent information loss.

The report includes a semantic match percentage and lists any facts that were lost or distorted during compression.

What It Does

• Converts verbose prose to dense tables (up to 3x more token-efficient)
• Removes filler words and passive constructions
• Restructures numbered lists to bullets where order does not matter
• Converts multi-line code blocks to inline code when a single expression suffices
• Merges redundant or overlapping sections
• Applies positive framing ("do Y" instead of "don't do X")
• Verifies all file paths (R.1), URLs (R.2), and circular references (R.3)
• Uses standard abbreviations in tables only (full words in prose)

Output

Each file produces an optimization report containing:

Files are modified in-place. The report is printed to the conversation.

Tips

• Start with light mode (-l) on important files to preview what changes look like before committing to deeper optimization.
• Review deep mode diffs carefully -- aggressive rephrasing can alter meaning in domain-specific content.
• Run without arguments to optimize all standard locations at once: CLAUDE.md, .claude/agents/*.md, .claude/skills/**/SKILL.md.
• Parallel processing kicks in automatically when you pass multiple files or a directory -- no extra flags needed.

Filler Words & Phrases to Remove

Apply filler removal from rules-review.md rule T.6. Additional deep-mode removals:

Structural Compression Patterns

• Conditionals: if X → Y or X ? Y : Z
• Prohibitions: !=X ∵Y (must not X because Y)
• Lists: inline comma-separated when items are short
• Tables: for multi-attribute data
• Merge related one-liners into single line with | separator
• Remove markdown formatting that doesn't aid parsing (bold, italic in tables)
• Headers: flatten to 2 levels max
• Remove blank lines between items in lists/tables

Iron Rules

Preserve in ALL cases regardless of compression level:

• Names, numbers, dates, URLs, file paths, versions, ports, sizes
• Negative rule semantics (use != notation)
• At least one example per rule that originally has examples
• DICT header at document start

Before/After Examples

Example 1 — Prose Instruction

Original (~60 words):

Please note that when you are working with the database connection, it is important to make sure that you close the connection after you are done with it. Failure to do so can result in connection pool exhaustion, which may lead to the application becoming unresponsive.

Compressed (~15 words):

DB conn: close after use ∵ unclosed → pool exhaustion → app unresponsive

Example 2 — Rule Block with DICT

Original (~90 words):

## File Handling Rules

>

When working with temporary files in the build directory, you should always use the project's file utility library. It is important to note that temporary files must be cleaned up after the build process completes. You must not write temporary files to the source directory because it can corrupt the version control state. The file utility library provides a cleanup() method that should be called in the finally block. All temporary files should use the .tmp extension.

Compressed (~35 words):

[DICT: TF=temporary files, FUL=file utility lib, BD=build dir]

>

## File Handling

TF in BD: use FUL | cleanup via cleanup() in finally block | ext: .tmp

!=TF in src dir ∵ corrupts VCS state

Example 3 — Configuration Section

Original (~70 words):

## Server Configuration

>

The application server runs on port 8443 with TLS enabled. The configuration file is located at /etc/myapp/server.yml. The minimum required version is Java 21. The maximum heap size should be set to 4096MB for production environments. Health check endpoint is available at https://localhost:8443/health. The connection timeout is 30 seconds and the read timeout is 60 seconds.

Compressed (~40 words):

## Server Config

Port: 8443 (TLS) | cfg: /etc/myapp/server.yml | Java >= 21

Heap max: 4096MB (prod) | health: https://localhost:8443/health

Timeouts: conn 30s, read 60s

Example 4 — Negative Rules

Original (~80 words):

## Security Rules

>

You must never store passwords in plain text in the configuration files. API keys should not be committed to the repository under any circumstances. It is important to make sure that you do not log sensitive information such as tokens or credentials at any log level. You should not disable TLS certificate verification in production environments because it exposes the application to man-in-the-middle attacks.

Compressed (~30 words):

## Security

!=plaintext passwords in cfg files

!=API keys in repo

!=log sensitive data (tokens, credentials) @ any log level

!=disable TLS cert verification in prod ∵ MITM exposure

LLM Text Optimization and Comprehension Rules

Categorized rules for LLM token efficiency and comprehension optimization with 41 rules across 6 categories. Apply by category. Reference specific IDs in reviews (e.g., "violates T.1").

C - Claude Behavior

T - Token Efficiency

S - Structure

R - Reference Integrity

P - Perception

L - LLM Comprehension

How content is perceived and processed by the LLM — not about token count but comprehension quality.

Rules NOT Recommended

Compression Ratios (Token Efficiency)

These ratios reflect token savings from applying T and S category rules. L category rules improve comprehension quality without necessarily reducing token count.

Compression References

Standard/deep modes apply ALL rules above (C + T + S + R + P) plus their respective compression reference.

Standard Compression Mode

1. Scope

Standard mode compresses text while keeping it human-readable. Target: 30-50% reduction. Unlike deep mode, output must remain clear to humans, not just LLMs. Use for README files, documentation, API references, and user-facing docs.

2. Filler Removal Patterns

Apply filler removal from rules-review.md rule T.6 as baseline. Standard mode additional patterns:

3. Structural Techniques

• Convert verbose paragraphs to bullet points when listing items
• Use tables for comparisons (3+ attributes across 2+ items)
• Merge paragraphs that repeat the same idea
• Replace long examples with concise ones
• Convert step-by-step prose to numbered lists
• Remove redundant section headers
• Combine related short sections

4. Abbreviation Rules (Conservative)

Only abbreviate in:

• Tables (space-constrained)
• Inline code references
• Well-known acronyms (API, URL, CLI, etc.)

Keep full words in prose for readability.

5. Verification Checklist

After compression, verify:

• [ ] All facts preserved (names, numbers, dates, URLs, paths, versions)
• [ ] No semantic changes to rules or instructions
• [ ] Negative rules remain negative
• [ ] Examples still present (at least one per concept)
• [ ] Document still readable by a human unfamiliar with the topic
• [ ] Compression ratio is 30-50%
• [ ] No information merged incorrectly (two different concepts collapsed into one)
• [ ] Headers and structure still logical

6. What NOT to Compress

• Code blocks (compress surrounding prose, not code)
• API signatures and parameters
• Error messages (exact text matters)
• Legal/compliance text
• Version numbers, dates, URLs
• Command-line examples

7. Before/After Examples

Example 1: README Intro

Before (~80 words):

CLAUDE.md

Overview

This is the CLAUDE.md configuration file for the KnowledgeHub project. KnowledgeHub is a comprehensive knowledge base management system that is built using Claude Code as the primary development tool. The KnowledgeHub platform allows teams to create, organize, and share knowledge base articles in a structured and searchable format. The current version of KnowledgeHub is 4.2.0, which was released with numerous improvements to the knowledge base indexing engine and the Claude Code integration layer. KnowledgeHub uses Claude Code for automated documentation generation, code review, and test scaffolding. The knowledge base system supports multiple formats including Markdown, HTML, and structured JSON documents.

Project Structure

The KnowledgeHub project follows a standard Node.js project structure. The main entry point is located at /src/main/index.ts, which initializes the Express server and sets up all middleware and route handlers. The knowledge base module is located in the /src/modules/knowledge/ directory, which contains the core logic for creating, reading, updating, and deleting knowledge base entries. The API layer is built on Express and exposes RESTful endpoints through https://api.example.com/v2 for external integrations.

src/
  main/
    index.ts          # Main entry point (port 3000)
  modules/
    knowledge/        # Knowledge base CRUD
    search/           # Full-text search engine
    auth/             # Authentication & authorization
  config/
    default.ts        # Default configuration
    production.ts     # Production overrides
  types/
    index.d.ts        # Type definitions

Commands

Architecture

Technology Stack

KnowledgeHub version 4.2.0 is built on the following technology stack. The backend is powered by Node.js with TypeScript, using Express as the web framework. The knowledge base data is stored in PostgreSQL with full-text search capabilities. Redis is used for caching knowledge base queries and session management. The frontend is built with React and communicates with the backend through the API at https://api.example.com/v2.

Server Configuration

The main server starts from /src/main/index.ts and listens on port 3000 by default. In production, the server is deployed behind an Nginx reverse proxy. The Claude Code integration connects to the knowledge base through internal APIs. Health checks are available at the /health endpoint. The knowledge base indexer runs as a background worker process.

Database Schema

The knowledge base stores articles in the kb_articles table with full-text search indexes. The kb_categories table organizes knowledge base entries into hierarchical categories. The kb_tags table provides a flexible tagging system for knowledge base content. Claude Code uses the knowledge base schema to generate accurate queries and mutations.

API Design

All API endpoints follow REST conventions and are versioned at https://api.example.com/v2. Authentication is handled via JWT tokens. Rate limiting is applied per API key. The knowledge base API supports pagination, filtering, and sorting. Claude Code generated the initial API scaffolding based on the OpenAPI specification.

Rules

Code Quality Rules

• NEVER commit code without running the full test suite first
• NEVER use any type in TypeScript - always define proper interfaces
• Do NOT use console.log for debugging in production code - use the Winston logger
• NEVER store secrets or API keys in source code or configuration files
• Do NOT bypass the authentication middleware for any API endpoint
• NEVER modify the knowledge base schema without creating a migration
• Do NOT use synchronous file operations in the server code
• NEVER expose internal error details in API responses to clients
• Do NOT skip code review for changes to the knowledge base module
• NEVER deploy to production without running the staging environment tests first

Git Rules

• NEVER force push to the main branch under any circumstances
• Do NOT create commits with messages shorter than 10 characters
• NEVER merge a pull request without at least one approval from the Claude Code review agent
• Do NOT rebase shared branches that other developers are working on

Performance Rules

• NEVER execute database queries inside loops - use batch operations instead
• Do NOT load entire knowledge base collections into memory
• NEVER skip database indexes for frequently queried knowledge base fields
• Do NOT make blocking HTTP calls in the request handling pipeline

Agents

developer

The developer agent is responsible for implementing features and fixing bugs in the KnowledgeHub codebase. This agent uses Claude Code to understand the existing code patterns and generate new code that follows the established conventions. The developer agent should reference the knowledge base module documentation when working on knowledge base related features. The agent works with version 4.2.0 of the KnowledgeHub platform.

reviewer

The reviewer agent performs code reviews on all pull requests. This agent uses Claude Code to analyze code changes for potential issues including security vulnerabilities, performance problems, and deviations from the knowledge base coding standards. The reviewer agent checks that all knowledge base operations follow the established patterns and that the API contracts defined at https://api.example.com/v2 are maintained.

tester

The tester agent is responsible for writing and maintaining the test suite for the KnowledgeHub platform. This agent uses Claude Code to generate test cases that cover both happy paths and edge cases. The tester agent ensures that the knowledge base module has comprehensive test coverage and that all API endpoints at https://api.example.com/v2 are properly tested. Tests must follow the GIVEN/WHEN/THEN pattern and use descriptive names.

Dependencies

KnowledgeHub version 4.2.0 depends on the following key packages:

Environment Variables

Deployment

KnowledgeHub 4.2.0 is deployed using Docker containers. The Dockerfile builds the TypeScript source from /src/main/index.ts and produces a minimal production image. The Docker Compose configuration starts the application on port 3000 along with PostgreSQL and Redis services. The Claude Code integration is configured through environment variables. The knowledge base data is persisted through Docker volumes.

Production Checklist

1. Ensure version 4.2.0 tag is created 2. Run full test suite against https://api.example.com/v2 3. Build Docker image from /src/main/index.ts 4. Deploy to staging on port 3000 5. Run smoke tests against staging 6. Deploy to production 7. Verify knowledge base indexing is operational 8. Monitor Claude Code integration health

DataSync Library

Introduction

DataSync is a powerful and easy-to-use data synchronization library that was built from the ground up to make it simple for developers to keep data in sync across multiple sources. The current version is 1.0.0 and it provides a robust and reliable mechanism for bidirectional data synchronization. Whether you are synchronizing data between a local database and a remote API, or between two different cloud services, DataSync provides the tools and abstractions you need to get the job done quickly and efficiently.

Installation

In order to install the DataSync library, you will first need to make sure that you have Node.js version 18 or higher installed on your system. You can check your current Node.js version by running node --version in your terminal. If you do not have Node.js installed, you can download it from the official Node.js website. Once you have confirmed that Node.js is installed and is the correct version, you can proceed with the installation of the DataSync library.

To install the library, open your terminal and navigate to your project directory. Then, run the following command to install the DataSync library as a dependency of your project:

npm install example-lib

After the installation has been completed successfully, you should verify that the library was installed correctly by checking your package.json file to make sure that example-lib is listed in the dependencies section. You may also want to run npm ls example-lib to verify the installed version is 1.0.0.

If you are using Yarn as your package manager instead of npm, you can install the library by running yarn add example-lib. For pnpm users, the command would be pnpm add example-lib. All three package managers are fully supported and will install the same version 1.0.0 of the library.

Features

DataSync version 1.0.0 provides a comprehensive set of features that are designed to handle various data synchronization scenarios. The library supports bidirectional synchronization, which means that changes made on either side of the sync are automatically propagated to the other side. This is particularly useful when you have multiple systems that need to stay in sync with each other.

Another important feature of DataSync is its conflict resolution system. When the same record is modified on both sides of the sync simultaneously, the library provides several strategies for resolving the conflict, including last-write-wins, merge, and custom resolver functions. The conflict resolution system is flexible and can be configured on a per-field basis.

DataSync also provides real-time sync capabilities through WebSocket connections. When real-time sync is enabled, changes are propagated immediately rather than waiting for the next sync cycle. This feature is useful for applications that require low-latency data updates.

The library also includes a comprehensive logging and monitoring system that allows you to track the status of sync operations, identify failures, and debug issues. The monitoring dashboard can be accessed through a web browser and provides real-time visibility into sync operations.

Additionally, DataSync supports batch operations for efficiently synchronizing large datasets. The batch sync feature can process thousands of records per second and includes built-in rate limiting to avoid overwhelming target systems.

Comparison of Sync Strategies

When choosing a synchronization strategy for your project, it is important to understand the trade-offs between the three available options. The Poll-based strategy works by periodically checking the source for changes at a configurable interval. This approach is simple to implement and understand, but it introduces latency because changes are only detected at the next poll interval. Poll-based sync is best suited for scenarios where near-real-time updates are not required and simplicity is preferred.

The Webhook-based strategy works by registering a webhook endpoint that is called whenever a change occurs on the source. This approach provides lower latency than polling because changes are pushed immediately. However, webhooks require the target system to be accessible over the network, which can be challenging in certain network configurations. Webhook-based sync is ideal for server-to-server integrations where both systems are reachable.

The WebSocket-based strategy establishes a persistent connection between the source and target systems. Changes are streamed in real-time through the WebSocket connection, providing the lowest possible latency. However, WebSocket connections consume more resources than the other two approaches and may not be suitable for scenarios with a very large number of connections. WebSocket-based sync is perfect for applications that require instant updates and can afford the resource overhead.

Quick Start

To get started with DataSync version 1.0.0, you first need to import the library into your project. It is important to understand that the library exports several modules, but for basic usage you only need to import the main DataSync class. The following example demonstrates how to set up a basic synchronization between two data sources. Please note that you should replace the placeholder values with your actual configuration. The source code for additional examples can be found in the repository at https://github.com/example/repo in the examples directory.

import { DataSync } from 'example-lib';

const sync = new DataSync({
  source: { type: 'postgres', connectionString: process.env.DATABASE_URL },
  target: { type: 'api', baseUrl: 'https://api.target.com/v1' },
  strategy: 'webhook',
  conflictResolution: 'last-write-wins'
