codebaxing CLAUDE.md

Project instructions for Codebaxing, a Node.js and TypeScript service that searches source code by meaning. It indexes functions, classes, and methods from many programming languages and finds related code for a natural-language query.

In plain words
What is it for?
Use it to understand the project structure, search for semantically related code, and work with its local code index. The instructions also describe its parsers, embeddings, and database.
Why use it?
It helps locate relevant code when you do not know the exact file name or wording to search for. This can be useful in large codebases where ordinary text search misses related implementations.

Getting it into your agent

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

codebaxing CLAUDE.md scanned grade A with 1 finding 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 2d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codebaxing (Node.js/TypeScript)

MCP server for semantic code search using vector embeddings.

How It Works

Source Code → Tree-sitter (AST) → Symbols → Embedding Model → Vectors → ChromaDB
                                                                            ↓
Query → Embedding Model → Query Vector → Cosine Similarity → Top-k Results
  1. Tree-sitter parses code into AST, extracts functions/classes/methods
  2. all-MiniLM-L6-v2 converts code chunks to 384-dim vectors (runs locally via ONNX)
  3. ChromaDB stores vectors for fast similarity search
  4. Search embeds query and finds nearest neighbors by cosine similarity

Code Search

Tool Purpose
index Index codebase. Modes: auto (incremental), full, load-only. Required first.
search Semantic search. Returns ranked code chunks with filters (language, symbol_type)
stats Index statistics (files, symbols, chunks)
languages Supported language extensions

Memory Layer

Tool Purpose
remember Store memories (conversation, status, decision, preference, doc, note)
recall Semantic search over memories
forget Delete memories by ID, type, tags, or age. Destructive.
memory-stats Memory statistics by type

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.

codebaxing CLAUDE.md is an instructions file published in the GitHub repository duysolo/codebaxing (53 stars, last pushed 5mo ago), licensed MIT. It adds 1,822 tokens to every session, about $0.0091 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
