Plugin Manifest
This is the reference for Lineup's plugin manifest file. The manifest tells Claude Code how to load and namespace the plugin.
File location
.claude-plugin/plugin.jsonThe file must be in a .claude-plugin/ directory at the plugin root. Claude Code discovers plugins by looking for this path.
Current manifest
{
"name": "lineup",
"description": "Structured multi-agent workflow: Clarify, Research, Plan, Implement, Verify, Document",
"version": "1.3.0",
"author": { "name": "izantech" },
"repository": "https://github.com/izantech/lineup"
}Fields
| Field | Type | Required | Description |
|---|---|---|---|
name | string | Yes | Plugin name. Becomes the namespace prefix for all skills and agents. |
description | string | Yes | One-line summary of the plugin's purpose. |
version | string | Yes | Semantic version string (major.minor.patch). |
author | object | Yes | Author information. |
author.name | string | Yes | Author name or organization. |
repository | string | No | URL to the source repository. |
How the namespace works
The name field determines the namespace prefix. Since Lineup's name is "lineup", all skills are registered under the lineup: prefix:
| Skill file | Registered command |
|---|---|
skills/kick-off/SKILL.md | /lineup:kick-off |
skills/configure/SKILL.md | /lineup:configure |
skills/explain/SKILL.md | /lineup:explain |
Agents are similarly namespaced. The agents/researcher.md file becomes lineup:researcher when loaded.
You don't type the namespace in skill or agent files -- it's added automatically by the plugin system based on this manifest field.
How versioning works
The version field follows semantic versioning:
- Major (1.x.x): Breaking changes to skills, agents, or tactic schema
- Minor (x.2.x): New features (agents, skills, tactics) that don't break existing workflows
- Patch (x.x.1): Bug fixes, prompt improvements, documentation updates
When you update the plugin, the version number indicates what changed:
# Marketplace update
claude plugin update lineup@izantechThe version is informational -- Claude Code doesn't enforce version constraints between plugins. It's used by the marketplace for update discovery.
Plugin structure
The manifest sits at the root of the plugin directory alongside all other components:
.claude-plugin/
plugin.json <-- Manifest
agents/
researcher.md <-- Loaded as lineup:researcher
architect.md
developer.md
reviewer.md
documenter.md
teacher.md
skills/
kick-off/
SKILL.md <-- Loaded as /lineup:kick-off
configure/
SKILL.md <-- Loaded as /lineup:configure
explain/
SKILL.md <-- Loaded as /lineup:explain
tactics/
explain.yaml <-- Built-in tactic
templates/
researcher.yaml <-- Document template schemas
architect.yaml
developer.yaml
reviewer.yaml
documenter.yaml
teacher.yaml
tactic.yaml
examples/
tactics/ <-- Example tactics for users to copyClaude Code discovers agents by scanning the agents/ directory for .md files, and skills by scanning skills/*/SKILL.md. Templates, tactics, and examples are referenced by the agents and skills but are not directly loaded by the plugin system.
Modifying the manifest
The manifest rarely needs modification. The main reasons to edit it:
- Forking the plugin: Change
nameto avoid conflicts with the upstream version. This changes the namespace prefix for all commands. - Custom distributions: Change
authorandrepositoryfor your organization.
WARNING
Changing the name field changes the namespace prefix. All commands change from /lineup:* to /newname:*. Existing tactics and documentation that reference /lineup: commands will need updating.
