Requirements validation and traceability tools - L-Space connects all libraries

Project description

elspais

"L-Space is the ultimate library, connecting all libraries everywhere through the sheer weight of accumulated knowledge." — Terry Pratchett

elspais is a requirements validation and traceability tool for teams managing formal requirements across one or more repositories. It validates requirement formats, enforces hierarchy rules, tracks changes with content hashes, and generates traceability matrices linking requirements to code and tests.

Installation

# Homebrew (macOS/Linux)
brew install anspar-org/anspar/elspais

# pipx (isolated install)
pipx install elspais

# pip
pip install elspais

Optional extras

pip install elspais[trace-view]    # Static HTML traceability view
pip install elspais[trace-review]  # Interactive viewer server
pip install elspais[mcp]           # MCP server for AI integration
pip install elspais[all]           # Everything

Quick Start

# Initialize configuration
elspais init

# Validate requirements
elspais validate

# Auto-fix hashes and formatting
elspais fix

# Generate traceability matrix
elspais trace --format html

# Interactive viewer (live server)
elspais viewer

# Built-in documentation
elspais docs

MCP Server (AI Integration)

elspais includes an MCP server for use with Claude Code, Claude Desktop, and other MCP-compatible clients.

# Install the MCP extra
pip install elspais[mcp]

# Register with Claude Code (all projects) and Claude Desktop
elspais mcp install --global --desktop

The MCP server provides tools for searching requirements, navigating hierarchies, checking coverage, and drafting mutations — all operating on the live traceability graph.

Requirement Format

Requirements are written in Markdown:

# REQ-d00001: Requirement Title

**Level**: Dev | **Status**: Active | **Implements**: REQ-p00001

## Assertions

A. The system SHALL provide user authentication via email/password.
B. Sessions SHALL expire after 30 minutes of inactivity.

*End* *Requirement Title* | **Hash**: a1b2c3d4
---
  • Hierarchy: PRD (product) → OPS (operations) → DEV (development)
  • Traceability: Children reference parents via Implements:
  • Assertions: Labeled A-Z, using SHALL for normative statements
  • Hash footer: SHA-256 content hash for change detection

Configuration

Create .elspais.toml in your repository root (or run elspais init):

[project]
name = "my-project"
type = "core"

[directories]
spec = "spec"
code = ["src"]

[patterns]
prefix = "REQ"
id_template = "{prefix}-{type}{id}"

[rules.hierarchy]
allowed_implements = ["dev -> ops, prd", "ops -> prd"]

[rules.format]
require_hash = true
require_assertions = true

See docs/configuration.md for full reference.

Multi-Repository Support

Link associated repositories that extend a core requirement set:

elspais init --type associated --associated-prefix CAL
elspais associate ../core-repo
elspais validate --mode combined
