Install Ddd Context

skills CLI
$ npx skills add ruvnet/ruflo --skill ddd-context -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install ruvnet/ruflo ddd-context --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/ruvnet/ruflo.git skills-src && mkdir -p .claude/skills && cp -r skills-src/plugins/ruflo-ddd/skills/ddd-context .claude/skills/ddd-context && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

What it does

Ddd Context is an agent skill from ruvnet/ruflo. Create and manage a DDD bounded context with standard directory structure. Use when starting a new subdomain, splitting a monolith into bounded contexts, or scaffolding the domain/application/infrastructure layout for a fresh module.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Domain-driven design. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

When your agent uses it

  • Starting a new subdomain
  • Splitting a monolith into bounded contexts
  • Scaffolding the domain/application/infrastructure layout for a fresh module

Example prompts

  • “/ddd-context”

Requirements

  • Pre-approved tools (allowed-tools): Bash, Read, Write, Edit, Grep, Glob, mcp__plugin_ruflo-core_ruflo__memory_store, mcp__plugin_ruflo-core_ruflo__memory_search, mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Validate name: Ensure the context name is kebab-case and does not already exist under src/.
  2. Create directory structure
  3. Generate index files
  4. Store in domain model graph
  5. Report: Confirm the context was created and list the generated files.

What it can do on your machine

Read from SKILL.md and the folder at commit de590e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • mcp__plugin_ruflo-core_ruflo__memory_store
    • mcp__plugin_ruflo-core_ruflo__memory_search
    • mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ddd Context loads about 564 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 126 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~564

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Write, Edit, Grep, Glob, mcp__plugin_ruflo-core_ruflo__memory_store, mcp__plugin_ruflo-c

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

argument-hint
<context-name>

Create a bounded context directory structure for the given context name.

Parse $ARGUMENTS as the context name (kebab-case). If empty, list existing contexts.

Steps

  1. Validate name: Ensure the context name is kebab-case and does not already exist under src/.

  2. Create directory structure:

    src/<context-name>/
  domain/
    entities/
    value-objects/
    events/
    services/
    repositories/
  application/
  infrastructure/

  3. Generate index files:

    • src/<context-name>/domain/entities/index.ts -- barrel export for entities
    • src/<context-name>/domain/value-objects/index.ts -- barrel export for value objects
    • src/<context-name>/domain/events/index.ts -- barrel export for domain events
    • src/<context-name>/domain/services/index.ts -- barrel export for domain services
    • src/<context-name>/domain/repositories/index.ts -- barrel export for repository interfaces
    • src/<context-name>/domain/index.ts -- re-export all domain submodules
    • src/<context-name>/application/index.ts -- barrel export for application services
    • src/<context-name>/infrastructure/index.ts -- barrel export for infrastructure implementations
    • src/<context-name>/index.ts -- public API of the bounded context (re-exports domain and application only, NOT infrastructure)

  4. Store in domain model graph:

    mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store --parent "domain" --child "context:<context-name>" --relation "contains"
mcp__plugin_ruflo-core_ruflo__memory_store --key "ddd-context-<context-name>" --value "Created bounded context" --namespace tasks

  5. Report: Confirm the context was created and list the generated files.

How do I install Ddd Context in Claude Code?

Run `npx skills add ruvnet/ruflo --skill ddd-context -a claude-code`. Or copy the skill folder (plugins/ruflo-ddd/skills/ddd-context in ruvnet/ruflo) into .claude/skills/ddd-context in your project. Claude Code loads it when a task matches its description.

How do I install Ddd Context in Codex?

Can I use Ddd Context in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill ddd-context -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ddd-context, .gemini/skills/ddd-context, .github/skills/ddd-context and .opencode/skills/ddd-context in your project.

What does Ddd Context need to run?

SKILL.md names no scripts, command-line tools or credentials: Ddd Context is instructions for the agent only. Its frontmatter pre-approves these tools: Bash, Read, Write, Edit, Grep, Glob, mcp__plugin_ruflo-core_ruflo__memory_store, mcp__plugin_ruflo-core_ruflo__memory_search, mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store.

Does Ddd Context access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Ddd Context safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Ddd Context use?

Ddd Context is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Ddd Context use?

About 564 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Ddd Context?
