LightSpec

AI-native spec-driven development tool. Create, manage, and apply specifications with your agent.

LightSpec Skill

LightSpec is a CLI tool that brings spec‑driven development to any AI‑assisted workflow. It helps you create feature specifications, track changes, and implement code based on those specs. This skill teaches your OpenClaw agent how to install, verify, update, uninstall, and use LightSpec effectively.

Installation

LightSpec requires Node.js (v18 or later). The agent can install it globally via npm:

text

npm install -g lightspec

If Node.js is not present, the agent should first install Node.js (platform‑specific instructions can be provided if needed).

Verification

To confirm LightSpec is installed correctly, run:

text

lightspec --version

The agent should expect a version number like 1.2.3. If the command fails, installation should be retried or the user notified.

Updating

To update LightSpec to the latest version:

text

npm update -g lightspec

After updating, verify again with lightspec --version.

Uninstalling

To remove LightSpec completely:

text

npm uninstall -g lightspec

Basic Usage

All LightSpec commands follow the pattern:

text

lightspec [command] [options]

Initialize a Project

Run inside a project directory to set up LightSpec:

text

lightspec init

This creates a lightspec/ folder and injects instructions into AGENTS.md (if present). The agent can then use the generated structure.

Create a New Feature Spec

text

lightspec change "User authentication"

Or using the spec subcommand (depending on version). The agent should inspect the output to see where the spec file was created (usually lightspec/changes/<change-name>/spec.md).

List Existing Changes or Specs

text

lightspec list          # list active changes
lightspec list --specs  # list all specs

View Interactive Dashboard

text

lightspec view

The agent can run this to get a high‑level overview of all changes and specs.

Validate a Spec or Change

text

lightspec validate [change-name]

Checks for completeness and consistency.

Apply a Change (Implement)

After a spec is approved, the agent can apply it to the codebase:

text

lightspec apply [change-name]

This command generates code or updates files based on the spec (implementation details depend on the project’s configuration).

Show Details of a Change or Spec

text

lightspec show [change-name]

Workflow Example

1. Initialize project (if not already done)

text

lightspec init

2. Create a change proposal

text

lightspec change "Add profile search filters by role and team"

3. Read the generated spec The agent can use read_file to inspect lightspec/changes/add-profile-search-filters/spec.md.

4. Ask the user what’s missing The agent can summarise the spec and point out gaps (e.g., missing acceptance criteria).

5. Validate the spec

text

lightspec validate add-profile-search-filters

6. Implement after approval

text

lightspec apply add-profile-search-filters

Tips for the Agent

• Always confirm with the user before running commands that change files (e.g., apply, init in an existing project).
• Use lightspec --help or lightspec help [command] if you need more details about a subcommand.
• LightSpec respects .lightspec/config.json for custom paths – the agent can read that to understand project‑specific settings.
• Refer to the official LightSpec documentation for the most updated information, guidence and how to guide the user.
