sdlc-plugins

Software Development Lifecycle (SDLC) plugins for AI coding agents, packaged using the Agent Plugins spec (v1.0.0).

What's Included

This plugin bundles a set of Agent Skills—reusable, discoverable instructions that an agent loads on demand based on the task at hand.

Skill	Description
sdlc-behavior-principles	Behavioral guardrails for planning, implementing, and reviewing changes: surface assumptions, keep solutions simple, make surgical diffs, and require verifiable checks.
verify-task	Enforces explicit proof of correctness (requirement, test, regression, diff, unproven) before a task is declared done.
code-documenter	Generates and maintains OKF-compliant knowledge bases documenting a codebase's modules, classes, functions, architecture, and configuration.

No MCP servers are configured in mcp.json at this time.

Installation

Add this repository as a plugin source in a client that supports the Agent Plugins spec, then enable sdlc-plugins. Consult your client's documentation for how to register a plugin by Git URL or local path.

GitHub Copilot CLI

This repository is also published as a plugin marketplace for GitHub Copilot CLI:

copilot plugin marketplace add dhanoopbhaskar/sdlc-plugins
copilot plugin install sdlc-plugins@sdlc-plugins

Usage

Once installed, skills are picked up automatically by the agent when their description matches the current task—no manual invocation is required. For example:

Ask the agent to plan, implement, or review a change and it will apply the sdlc-behavior-principles guardrails.
Ask the agent to confirm a task is complete and it will apply the verify-task checklist.
Ask the agent to document a codebase and it will apply the code-documenter workflow.
