+# Contentstack Utils Ruby – Agent guide
+
+**Universal entry point** for contributors and AI agents. Detailed conventions live in **`skills/*/SKILL.md`**.
+
+## What this repo is
+
+| Field | Detail |
+|--------|--------|
+| **Name:** | [contentstack/contentstack-utils-ruby](https://github.com/contentstack/contentstack-utils-ruby) |
+| **Purpose:** | Ruby gem that renders Contentstack rich text and JSON RTE (including GraphQL-shaped payloads) to HTML, with pluggable rendering via `ContentstackUtils::Model::Options` subclasses. |
+| **Out of scope (if any):** | This package does not ship an HTTP client or stack SDK; it pairs with the separate Contentstack Ruby delivery client for entry data and `_embedded_items`. |
+
+## Tech stack (at a glance)
+
+| Area | Details |
+|------|---------|
+| Language | Ruby **≥ 3.1** (see `contentstack_utils.gemspec` and `.ruby-version` for local dev) |
+| Build | **Bundler** + **RubyGems**; `contentstack_utils.gemspec`, `Gemfile` |
+| Tests | **RSpec**; specs under `spec/**/*_spec.rb`, loaded via `spec/spec_helper.rb` |
+| Lint / coverage | No RuboCop in-repo; **SimpleCov** in `spec/spec_helper.rb`; API docs via **YARD** (`.yardopts`, `rake yard`) |
+| Runtime deps | **activesupport** (7.x), **nokogiri** (HTML / XML for legacy RTE strings) |
+
+## Commands (quick reference)
+
+| Command type | Command |
+|--------------|---------|
+| Install deps | `bundle install` |
+| Build (default task) | `bundle exec rake` (runs **spec**) |
+| Test | `bundle exec rake spec` or `bundle exec rspec` |
+| Docs | `bundle exec rake yard` |
+
+**CI / automation:** There is no dedicated workflow that runs `rspec` on every push; local verification is `bundle exec rake`. Other workflows include branch checks (PRs into `master`), release publish, CodeQL, policy/SCA scans—see `.github/workflows/`.
+
+## Where the documentation lives: skills
+
+| Skill | Path | What it covers |
+|-------|------|----------------|
+| Code review | `skills/code-review/SKILL.md` | PR checklist for this gem |
+| Contentstack Utils SDK | `skills/contentstack-utils/SKILL.md` | Public API, models, CDA vs GQL paths, versioning |
+| Development workflow | `skills/dev-workflow/SKILL.md` | Branches, Bundler/Rake, gem build, workflows |
+| Framework & packaging | `skills/framework/SKILL.md` | Gemspec, dependencies, Ruby version, release |
+| Ruby style and layout | `skills/ruby-style/SKILL.md` | Module layout, naming, matching existing code |
+| Testing | `skills/testing/SKILL.md` | RSpec layout, mocks, SimpleCov, WebMock |
+
+An index with “when to use” hints is in `skills/README.md`.
+
+## Using Cursor (optional)
+
+If you use **Cursor**, **`.cursor/rules/README.md`** is the only file under `.cursor/rules`; it points to **`AGENTS.md`**—same docs as everyone else.

+# Code review – Contentstack Utils Ruby
+
+## When to use
+
+- Authoring a pull request that changes rendering, models, or dependencies
+- Reviewing someone else’s PR before merge
+- Checking release readiness (version + changelog)
+
+## Instructions
+
+### Blockers (fix before merge)
+
+- **Tests:** `bundle exec rake` (or `bundle exec rspec`) passes locally
+- **Breaking API:** unintended removal or signature change of public methods on **`ContentstackUtils`**, **`ContentstackUtils::GQL`**, or **`ContentstackUtils::Model::Options`** without version bump and changelog entry
+- **Security:** no secrets in code, fixtures, or logs; HTML output changes reviewed for injection or XSS risk when embedding untrusted fields
+
+### Major (should address)
+
+- **CHANGELOG.md** updated for user-visible behavior fixes or features
+- **`lib/contentstack_utils/version.rb`** updated when publishing a release (if this PR is release-bound)
+- New JSON/RTE node types or GQL shapes covered by **`spec/lib/utils_spec.rb`** (or focused new spec files)
+- Dependency range changes in **`contentstack_utils.gemspec`** justified and compatible with Ruby **≥ 3.1**
+
+### Minor (nice to have)
+
+- **README.md** examples match actual class names (**`Options`**, not a non-existent **`Option`** unless aliased)
+- YARD or comments only where they clarify non-obvious RTE or GQL mapping
+
+### Process
+
+- Respect **CODEOWNERS** and branch policy (**`master`** vs **`staging`**) described in [dev-workflow](../dev-workflow/SKILL.md)

+# Contentstack Utils SDK – Contentstack Utils Ruby
+
+## When to use
+
+- Implementing or fixing HTML output for rich text / JSON RTE
+- Extending or subclassing rendering options (`ContentstackUtils::Model::Options`)
+- Parsing GraphQL-shaped RTE (`ContentstackUtils::GQL`)
+- Changing load paths or public entry points under `lib/` (gemspec and dependency ranges: see [framework](../framework/SKILL.md))
+
+## Instructions
+
+### Entry points
+
+- **`lib/contentstack_utils.rb`** — requires version and `utils`
+- **`lib/contentstack_utils/utils.rb`** — main module **`ContentstackUtils`** with class methods:
+  - **`render_content(content, options)`** — legacy HTML string RTE (array of strings or single string); uses Nokogiri and `_embedded_items` on the entry passed via options
+  - **`json_to_html(content, options)`** — JSON RTE document tree (Hash/Array) for CDA-style payloads with embedded items on the entry
+  - Internal helpers such as **`json_doc_to_html`** (used by GQL path)
+- **`ContentstackUtils::GQL`** — **`json_to_html(content, options)`** for GraphQL responses: expects keys like `json` and optional `embedded_itemsConnection.edges`; reuses `ContentstackUtils.json_doc_to_html` with a GQL-specific reference resolver
+
+### Models and extension points
+
+- **`ContentstackUtils::Model::Options`** (`lib/contentstack_utils/model/options.rb`) — default **`render_option`**, **`render_mark`**, **`render_node`**; subclass for custom HTML (see tests under `spec/mock/custom_render_option.rb`)
+- **`ContentstackUtils::Model::Metadata`** — built from DOM nodes (HTML path) or JSON reference nodes
+- **`ContentstackUtils::Interface::Rendarable`** (`lib/contentstack_utils/interface/renderable.rb`) — base for options; implement **`render_option`** in subclasses
+
+### Data contracts
+
+- **CDA / delivery JSON path:** options may carry an **`entry`** hash with **`_embedded_items`** keyed by field UIDs
+- **GQL path:** payload uses **`embedded_itemsConnection.edges`** with **`node`** objects; reference resolution matches **`metadata.item_uid`** to **`node.system.uid`**
+
+### Boundaries
+
+- HTTP and stack access belong to the separate **Contentstack Ruby** client; this gem only renders given content + embedded metadata
+
+### Versioning
+
+- Public API and behavior changes should be reflected in `CHANGELOG.md` and `lib/contentstack_utils/version.rb`

+
+## When to use
+
+- Cloning the repo or onboarding a new contributor
+- Running tests, generating docs, or building the gem locally
+- Understanding branch rules and GitHub Actions for this repository
+
+## Instructions
+
+### Prerequisites
+
+- Ruby **≥ 3.1** (matches `s.required_ruby_version` in `contentstack_utils.gemspec`)
+- Bundler; install gems with `bundle install`
+
+### Everyday commands
+
+- **Run tests (default Rake task):** `bundle exec rake` or `bundle exec rake spec`
+- **RSpec directly:** `bundle exec rspec` (pattern `spec/**/*_spec.rb` is configured in `Rakefile`)
+- **YARD API docs:** `bundle exec rake yard` (see `.yardopts` for included paths)
+- **Build gem artifact:** `gem build contentstack_utils.gemspec` (also used in `.github/workflows/release-gem.yml`)
+
+### Version and changelog
+
+- Gem version lives in `lib/contentstack_utils/version.rb` as `ContentstackUtils::VERSION`
+- Document user-visible changes in `CHANGELOG.md` when releasing
+
+### Branches and PRs
+
+- `.github/workflows/check-branch.yml` blocks merging into **`master`** unless the head branch is **`staging`** (organizational policy). Prefer PRs that follow team conventions for `master` / `staging`.
+- Use `CODEOWNERS` for required reviewers when applicable
+
+### CI and automation (no RSpec workflow today)
+
+- **Release:** `.github/workflows/release-gem.yml` — on GitHub **release created**, builds and pushes to RubyGems (note: workflow pins Ruby 2.7 for publish; align with gemspec minimum when changing)
+- **Security / compliance:** CodeQL, policy scan, SCA scan — see `.github/workflows/`
+- **Issues:** Jira integration workflow in `.github/workflows/issues-jira.yml`
+
+### Optional housekeeping
+
+- `.talismanrc` is used for secret scanning hooks in some environments; do not commit credentials or tokens

+
+# Framework & packaging – Contentstack Utils Ruby
+
+## When to use
+
+- Editing **`contentstack_utils.gemspec`** (dependencies, `required_ruby_version`, files list)
+- Changing **`Gemfile`** / **`Gemfile.lock`** workflow or documenting install for contributors
+- Evaluating impact of **nokogiri** (native extension) or **activesupport** version ranges on consumers
+
+## Instructions
+
+### Gem definition
+
+- **`contentstack_utils.gemspec`** — canonical metadata: `s.files` from `git ls-files`, `spec/` as test files, `lib` as `require_paths`
+- **`Gemfile`** — `gemspec` only; runtime and development dependencies are declared in the gemspec
+
+### Runtime dependencies (as shipped)
+
+- **activesupport** `>= 7.0`, `< 8`
+- **nokogiri** `>= 1.13`, `< 1.19` — HTML/XML parsing for legacy string RTE paths; consumers need a compatible platform build
+
+### Development dependencies
+
+- **rake**, **rspec**, **webmock**, **simplecov**, **yard** — see gemspec; used for tasks in `Rakefile` and CI-style local checks
+
+### Ruby version
+
+- **`s.required_ruby_version`** is **>= 3.1**; `.ruby-version` pins a team default for local dev
+- **Release workflow** (`.github/workflows/release-gem.yml`) uses its own Ruby pin for `gem build` / `gem push`; keep it aligned with gemspec when updating
+
+### Build and publish
+
+- Local artifact: `gem build contentstack_utils.gemspec`
+- Publishing is triggered by GitHub **release** per `release-gem.yml`
