CandleKeep is a library your AI agents read while they work — they open a book, find the page, and cite it.
No vector search. Agents read pages directly, like a person reading a book — and cite them.
Books are structured into pages and tables of contents so agents can actually read them.
It's a library of outside expertise for your agent, not an internal wiki to govern.
No vector databases. No RAG pipelines. Your agent checks the table of contents, picks the right chapter, and reads the relevant pages.
One command installs CandleKeep. Your agent detects research questions automatically — no manual references, no configuration per conversation.
Your agent reads like a developer explores a codebase. Table of contents first, then relevant chapters, then specific pages. No keyword search. No vector similarity. Actual reading.
Training data is like remembering a book you read 3 years ago. CandleKeep is like having it open on your desk. Every answer includes the source and page number.
Define a knowledge area. Your agent proposes additions from every coding session. Over time, it builds a structured book from your real experience.
Topics: race conditions · async · deadlocks
Chapters written by your agent:
Built from 47 coding sessions
Define topics and criteria. Your agent handles the rest.
Knowledge accumulates automatically from your real work.
Who it's for
However you build with AI, CandleKeep gives your agents the knowledge they were missing.
This is you if… You build agents, tools, MCP servers, or skills in Claude Code, Cursor, or Codex.
Inject the domain knowledge your agent's training data doesn't have.
This is you if… You're shipping with AI without a deep background in the domain.
Hand your agent the right book and it instantly works like a specialist.
This is you if… Your team runs many agents that all start from zero.
Give every agent the same curated, cited knowledge — and let them write back what they learn.
CandleKeep integrates with the agents and platforms you already use.

Platforms & Interfaces
Your agent handles the code. CandleKeep gives it the domain knowledge.
Your agent reads the security textbook so it audits code like a specialist, not a generalist.

An LLM wiki is a knowledge base your AI agent writes and maintains itself — so your knowledge compounds across sessions instead of being re-derived every time. If you use Claude Code seriously, you've probably already hacked one together. Here's the version that took me an afternoon to build — because it was just a book.
Read moreA security researcher found vulnerabilities in my website. I used it as an experiment: plain AI agent vs. agent armed with 3,910 pages of security knowledge. The book-equipped agent found 8x more critical issues.
Read moreAfter 10 years building backend systems, I discovered why AI agents fail at UI design — and wrote the first book meant only for agents, not humans.

The first library built for agents — in an era where everyone has access to powerful models, the model's knowledge becomes the baseline and the competitive edge shifts to the layer below it: the data and context the model can see.
Curated knowledge libraries any AI agent can pull from on demand — web security, design, product strategy, and more.
Agent-optimized webapp security reference
An architectural analysis of Claude Code -- the internal agent schema, built-in agents, coordinator system, hooks, memory, and token-optimization decisions. Written from source analysis, in our own words.
A 20,000-word, 12-chapter technical book by Sahar Carmel about building multi-agent AI systems. Covers architecture, memory systems, knowledge systems (books over RAG), inter-agent communication, security, deployment, and development workflows.
A comprehensive reference manual for AI agents building web and mobile interfaces. 15 self-contained chapters covering visual hierarchy, typography, color systems, spacing, component patterns, navigation, cognitive load, behavioral triggers, persuasion, form design, responsive design, accessibility, and anti-patterns. Synthesized from 10 foundational UI/UX books (Refactoring UI, Don't Make Me Think, Laws of UX, 100 Things Every Designer, Hooked, Influence) into 170+ concrete, actionable rules with specific thresholds, values, and anti-patterns. Each rule uses When/Do/Values/Don't format for direct agent application.

A comprehensive guide from Anthropic Engineering on building effective tools for AI agents, covering a three-phase methodology of prototyping, evaluation, and optimization. Covers tool design principles including search over listing, consolidation, namespacing, response design, token efficiency, error handling, and description engineering for optimal agent performance.

CandleKeep
CandleKeep gives your agent domain expertise.
Everything you need to know before getting started.
One command installs the CLI, authenticates, and connects your agents.
curl -fsSL https://getcandlekeep.com/install.sh | shInstalls the CLI, authenticates, and configures Claude Code, Codex, and Cursor.
Scan this codebase and set up my CandleKeep library for this project. 1) Analyze the repo — languages, frameworks, architecture, and domain areas. 2) Browse the marketplace and subscribe to the top 3–5 most relevant books. 3) Explain why each book helps this codebase. 4) Suggest documents I should upload from my own knowledge.
Paste it into Claude Code, Cursor, or Codex after installing — your agent curates its own starting library.
