The best agent skills in the world for software development.
How to install Blueprint in Codex
In Codex, ask the built-in skill installer for it:
$skill-installer install https://github.com/owainlewis/blueprint/tree/main/skills/<skill>Type this in Codex and replace <skill> with a folder name from 'What it contains'. $skill-installer is the skill installer built into Codex, and it downloads the skill from GitHub. Restart Codex if the skill doesn't show up. Check the repo README for any setup it needs. Source: Codex skills docs.
Or copy the skill folder (the one with SKILL.md) into ~/.agents/skills to use it in every project, or into .agents/skills in a repo to share it with that repo. Codex picks up new skills automatically. (where Codex loads skills)

What it contains
Skills (11)
architecture-review— Reviews a technical proposal before implementation. Use for system architectures, feature specs, RFCs, ADRs, and issues that define how a system change should work. Finds material ambiguity and flaws in correctness, scalability, performance, security…architecture— Designs and maintains root ARCHITECTURE.md for the intended system, including its data model and shared technical rules. Use for new systems or changes to system boundaries, ownership, storage, or deployment.codex-issue-coordinator— Coordinates a large batch of GitHub issues through separate Codex worker threads, tested pull requests, review loops, and gated merges. Use when the user asks one Codex thread to manage several coding sessions or complete a parent issue, milestone, or issue…factory— Delivers a spec or decided task through the task-to-pr workflow and merges after all quality and approval gates pass. Explicit invocation grants merge authority for the supplied work.html-doc— Generates a polished, static HTML reading view from an existing Markdown PRD or technical design. Use when a user asks to render, present, visualize, or make a PRD or design document easier for humans to read in a browser.improve— Makes existing code easier to understand without changing behavior. Use to simplify structure, remove duplication or dead code, improve names, or remove unnecessary abstractions.plan— Turns a reviewed spec or decided brief into ordered tasks for separate agent runs. Use for implementation tasks, tracker tickets, or useful milestones. Do not use for one coding task or its short execution outline.requirements— Defines system product requirements: users, outcomes, capabilities, business rules, scope, and acceptance. Use for a new service or system, or a change to its product expectations.review— Uses a fresh agent to review an implementation change without editing it. Checks behavior, security, regressions, complexity, tests, docs, and missing proof. Use for code, PR, diff, security, second-opinion, or pre-merge reviews.spec— Defines one feature or major change: required behavior, technical design, failure handling, and acceptance checks. Use when consequential decisions must be settled before delivery. The spec is the ticket.task-to-pr— Delivers specs or decided tasks as tested, independently reviewed pull requests. Runs the CI and review repair loop, then leaves passing pull requests open unless merging was explicitly authorized.
