codebase-recall

High-performance CLI codebase context dumper for LLMs and AST-based code relation grapher.

codebase-recall (code-rcl) is a command-line tool built with Rust 🦀 designed for two primary developer workflows:

  1. Context Bundling for LLMs: Scan your directory structure and bundle your codebase—or a focused, dependency-aware slice of it—into a clean, well-structured Markdown document ready for LLMs (ChatGPT, Claude, Gemini, DeepSeek).
  2. Code Relation Graph & Architecture Visualization: Parse ASTs across multiple languages (Rust, JS/TS, Python, Java, Kotlin, Vue, Svelte) to discover definitions, imports, and cross-file calls. Visualize interactions in real-time in an interactive browser UI or export to self-contained HTML, Graphviz DOT, or JSON.

Key Features

📦 Codebase Context Dumper (dump)

  • Full & Targeted Dumps:
    • Full Dump: Pack the entire repository with directory trees and filtered source contents.
    • Targeted / Relation-Aware Dump (-r / --relation): Provide a target symbol or file; code-rcl traverses the dependency graph up to --depth <N> and dumps only connected and relevant files—saving prompt tokens and eliminating hallucination noise.
  • Smart Filtering:
    • Automatically respects .gitignore rules and ignores hidden directories (.git/, .cache/, etc.).
    • Skips binary files, media assets (.png, .webp, .pdf, etc.), lockfiles (Cargo.lock, package-lock.json, pnpm-lock.yaml, bun.lockb, etc.), minified bundles (.min.js, .chunk.js), and sensitive environment files (.env*).
  • Safe Dynamic Markdown Fencing: Detects the maximum backtick streak in file contents and dynamically expands markdown fences (e.g. ```` or `````) to prevent nested markdown from breaking document formatting.
  • Size Limits & Path Normalization: Configurable per-file size limit (default: 50 KB) and automated path separator normalization across OS platforms.

🕸️ Code Relation Graph (graph & serve)

  • Multi-Language AST Parsing: Powered by tree-sitter for Rust, JavaScript/JSX, TypeScript/TSX, Python, Java, Kotlin, and Single-File Components (Vue, Svelte).
  • Multi-Tier Resolution: Tracks symbols (functions, structs, classes, enums, methods), imports, and call references across files with confidence scoring.
  • Incremental SQLite Caching: Stores file hashes (Blake3) and AST entities in .code-rcl/cache.db. Re-runs only parse files modified since the last sync.
  • Interactive Browser Viewer (serve):
    • Instant local visualization powered by vendored d3-force simulation (smooth zoom, pan, and drag).
    • Toggle edge kinds (imports, calls, references).
    • Interactive search filtering, node isolation, cluster expansion/collapsing, and press-and-hold node spotlighting.
    • Interactive BFS depth adjuster directly inside the web UI.
    • Zero Background Footprint: Uses a lightweight EventSource heartbeat; the local server automatically terminates when you close your browser tab.
  • Export Formats (graph): Standalone zero-dependency HTML, Graphviz .dot, and structured JSON (version: 1).

Subcommands Overview

code-rcl is organized into subcommands:

Command Description
code-rcl dump Bundle the codebase (or a symbol's neighborhood) into a single Markdown file for LLM context.
code-rcl init Initialize .code-rcl/ (SQLite cache DB + config.toml) and ensure it is in .gitignore.
code-rcl sync Incrementally parse changed source files into the graph cache.
code-rcl graph Auto-sync, then export the relation graph to file(s) (html, json, dot).
code-rcl serve Auto-sync, then host an interactive relation graph in the browser; exits when the tab closes.

Usage — dump (LLM Context Generator)

1. Standard Full Dump

Scan the repository and produce a comprehensive codebase-context.md:

# Scan current directory -> codebase-context.md

code-rcl dump


# Scan specific project directory and specify output filename

code-rcl dump ./path/to/project -f context.md


# Increase per-file size limit to 100 KB

code-rcl dump . --max-size-kb 100 -f full-context.md

2. Relation-Aware / Targeted Dump

When working with large codebases, dumping everything can exceed token context windows or degrade LLM reasoning. Use --relation (-r) to extract only the target file/symbol and its connected dependency neighborhood:

# Dump only files connected to `build_graph` within 2 degrees of relationship

code-rcl dump -r build_graph


# Dump files connected to a specific module/file with a custom depth of 3

code-rcl dump -r src/commands/dump.rs --depth 3 -f dump-feature-context.md


# Skip auto-sync if cache is already fresh

code-rcl dump -r App --no-sync

dump Options

Flag / Option Short Default Description
[PATH] - . Target project directory path to scan
-f, --file <PATH> -f codebase-context.md Path or name of the output Markdown file
--max-size-kb <N> - 50 Maximum file size (in KB) for content extraction
-r, --relation <NAME> -r None Restrict dump to the target symbol/file and its connected dependency graph
--depth <N> - 2 BFS traversal depth when using --relation
--no-sync - false Do not re-sync graph cache before building targeted relation dump

Output Markdown Structure

> **Targeted dump**: focused on `build_graph` with depth 2.

Usage — Code Relation Graph (init, sync, graph, serve)

Quick Setup

# 1. Initialize .code-rcl/ in your project (creates cache.db and config.toml)

code-rcl init


# 2. Parse source files into cache (Blake3-based incremental indexing)

code-rcl sync

code-rcl graph (File Output)

Generates static graph visualizations in standalone HTML, DOT, or JSON format:

# Default: auto-syncs and outputs .code-rcl/code-graph.html

code-rcl graph


# Generate HTML, JSON, and DOT files simultaneously

code-rcl graph --format html,json,dot -o build/graph


# File-level dependency graph only (imports between files)

code-rcl graph --scope file --min-confidence 0.7


# Focus on a specific symbol and its immediate neighborhood

code-rcl graph --focus App --depth 2


# Limit graph nodes to prevent cluttered views

code-rcl graph --max-nodes 2000

graph Options

Flag Default Description
--project <PATH> . Project directory (cache stored in <project>/.code-rcl/)
--format <LIST> html Comma-separated output formats: html, json, dot
-o, --output <PATH> .code-rcl/code-graph.<ext> Output file or path stem when requesting multiple formats
--scope <MODE> both Graph scope: file (imports only), symbol, or both (layered)
--kinds <LIST> imports,calls,contains Edge kinds to include (imports, calls, contains, references)
--path <GLOB> None Filter source files by glob pattern
--focus <NAME> None Restrict graph to the neighborhood of a symbol or file
--depth <N> 2 BFS traversal depth around --focus
--min-confidence <F> 0.4 Filter out resolved edges below this confidence score [0.0 - 1.0]
--include-external false Include external dependencies (npm, PyPI, crates.io packages)
--max-nodes <N> 4000 Node cap; drops lowest-degree symbols if exceeded (0 to disable)
--no-sync false Render directly from cache without checking/re-parsing modified files

code-rcl serve (Interactive Browser Viewer)

code-rcl serve resolves the graph and hosts an interactive UI on a local HTTP server (127.0.0.1), automatically opening your default browser.

# Build, sync, and launch the interactive viewer on a free port

code-rcl serve


# Pin port and do not launch browser automatically

code-rcl serve --port 8080 --no-open


# Apply filters directly when serving

code-rcl serve --scope symbol --focus handle_request --depth 3

How serve Works

  • Self-Terminating / Zero Background Leak: An active browser tab maintains an EventSource connection (/live). Closing the browser tab drops the connection, causing the server to cleanly exit within 2 seconds.
  • Ctrl-C: Instantly halts the server.
  • No External Network Dependencies: D3.js and frontend styles are bundled inside the binary; no external CDNs or network connections are made.

Browser UI Features

  • Force Simulation: Real-time physics layout with smooth zooming, panning, and node dragging.
  • Dynamic Filtering: Checkbox controls for imports, calls, and references.
  • Search & Isolate: Real-time search bar with instant node filtering and single-click node isolation.
  • Live Depth Controls: Adjust BFS depth (+ / -) directly from the browser navigation bar.
  • Node Spotlighting: Long-press any node to spotlight its immediate connections while dimming the rest of the graph.

Edge Resolution & Confidence Scoring

Relationships between symbols and files are resolved via multi-tier heuristics:

  1. Import Edges (confidence = 1.0): Language-specific path and module resolution.
  2. Local References (confidence = 0.95): Definitions and references within the same lexical scope or file.
  3. Imported Calls (confidence = 0.8 - 0.9): Calling an identifier explicitly imported from another module.
  4. Project-Wide Unique Match (confidence = 0.6 - 0.7): Unambiguous reference matching a unique exported symbol across the workspace.
  5. Receiver / Method Match (confidence = 0.4 - 0.5): Associated methods matched by signature and receiver heuristics.

Adjust --min-confidence (default: 0.4) to fine-tune graph density.

JSON Schema (--format json, version: 1)

When exporting with code-rcl graph --format json, the output conforms to this structure:

{
  "version": 1,
  "root": "/path/to/project",
  "generated_at": 1730000000,
  "nodes": [
    {
      "id": "file:src/main.rs",
      "kind": "file",
      "label": "src/main.rs",
      "path": "src/main.rs",
      "language": "rust",
      "exported": true
    },
    {
      "id": "sym:src/main.rs#main@10",
      "kind": "function",
      "label": "main",
      "path": "src/main.rs",
      "language": "rust",
      "exported": false
    }
  ],
  "edges": [
    {
      "source": "file:src/main.rs",
      "target": "file:src/cli.rs",
      "kind": "imports",
      "confidence": 1.0
    },
    {
      "source": "sym:src/main.rs#main@10",
      "target": "sym:src/commands/dump.rs#run@10",
      "kind": "calls",
      "confidence": 0.85
    }
  ]
}

Configuration (config.toml)

Running code-rcl init creates .code-rcl/config.toml in your project root:

# code-rcl project configuration

schema_version = 1



[sync]

# Skip source files larger than this many KB

max_file_kb = 512

# Languages to analyze

languages = ["rust", "javascript", "typescript", "python"]



[graph]

# Drop resolved edges below this confidence

min_confidence = 0.4

# Include edges to external (npm / pypi / crate) modules

include_external = false
