This kit provides a systematic approach to developing AI agents and commands, grounded in Anthropic's best practices. It helps automation builders move from raw prompts to validated skills through rigorous evaluation and structured specification.
The collection includes tools for root cause analysis, task drafting, and knowledge base reconciliation, ensuring that agent behavior remains aligned with the current state of a repository.
Follow the documented setup, then try a first task.
Installs: The Spec-Driven Development (sdd) plugin and its specific commands, agents, and skills. · Claude Code
In a Claude Code agent session, add the Context Engineering Kit marketplace once.
/plugin marketplace add NeoLabHQ/context-engineering-kit
In the Claude Code agent session, install the sdd plugin.
/plugin install sdd@NeoLabHQ/context-engineering-kit
Installs: The kaizen plugin, including its root-cause-analysis capabilities such as Five Whys. · Claude Code
In a Claude Code agent session, add the Context Engineering Kit marketplace once.
/plugin marketplace add NeoLabHQ/context-engineering-kit
In the Claude Code agent session, replace the author-provided `<plugin-name>` placeholder with `kaizen`, then enter the documented command.
/plugin install <plugin-name>@NeoLabHQ/context-engineering-kit
Installs: The First Principles Framework (fpf) plugin and its structured-reasoning knowledge-base commands. · Claude Code
In a Claude Code agent session, add the Context Engineering Kit marketplace once.
/plugin marketplace add NeoLabHQ/context-engineering-kit
In the Claude Code agent session, replace the author-provided `<plugin-name>` placeholder with `fpf`, then enter the documented command.
/plugin install <plugin-name>@NeoLabHQ/context-engineering-kit
Installs: Every Context Engineering Kit plugin's skills and agents as one bundle; Gemini CLI does not support per-plugin selection. · Gemini CLI
Run this command in a terminal. It installs the repository as one complete bundle.
gemini extensions install https://github.com/NeoLabHQ/context-engineering-kit
Installs: A user-selected set of Context Engineering Kit skills and agents; this option selects create-ideas, why, and status. · Cursor, Antigravity, Codex, OpenCode
Run this command in a terminal. When the installer asks which skills and agents to install, select `create-ideas`, `why`, and `status`.
npx skills add NeoLabHQ/context-engineering-kit
Installs: Skills installed from the Context Engineering Kit repository and synchronized through OpenSkills. · Cursor, Antigravity, Codex, OpenCode
Run both commands in a terminal, in the documented order, to install the repository through OpenSkills and then synchronize the skills.
npx openskills install NeoLabHQ/context-engineering-kit npx openskills sync
Uses create-ideas
Use the create-ideas skill to generate six genuinely different responses to this question: [question or problem]. Include text and a numeric probability for each response, with three likely answers above 0.80 and three diverse tail ideas below 0.10.
Uses why
Use the why skill to analyze this issue with the default depth of five: [issue description]. State the problem clearly, document each why, validate the causal chain backward, explore branches if multiple causes emerge, and propose solutions that address the root causes.
Uses status
Use the status skill in [project directory] to inspect the existing `.fpf/` knowledge base. Report whether it is initialized, its current phase, hypothesis counts by layer, evidence freshness, decision count, and any warnings. Do not reset or modify the knowledge base.
No starter task is available for this installation option.
