When code costs almost nothing, the plan becomes the product.

A V-Model workflow that walks your AI coding assistant through Business Analysis, Requirements Engineering, Architecture, Coding, Testing, and a Security Audit, with quality-gated handoffs between every phase.

Full documentation: pssah4.github.io/digital-innovation-agents

Shipping code is a solved problem. What most teams still lack is evidence that the features they ship matter to a real user. Digital Innovation Agents pair a battle-tested innovation methodology with a state-of-the-art coding workflow, so your AI never builds the wrong thing at speed. Works across Claude Code, Cursor, Codex, OpenCode, Gemini CLI, and GitHub Copilot.

What this is

The project ships thirteen skills that run inside your AI coding assistant. Six are V-Model phase skills (business analysis, requirements engineering, architecture, coding, testing, security audit). Two are entry-point skills for non-greenfield projects (reverse engineering, dia-migration). One is the on-demand workflow guide (/dia-guide). Four are foundation skills (project conventions, consistency check, humanizer, dia-bootstrap). Every phase skill owns one part of the V-Model, has its own quality gates, and hands off a structured artifact to the next phase. The guide is called separately whenever the user wants an orientation read. Every decision stays traceable from a real user problem through requirements, architecture, code, tests, and a security audit.

Three entry points cover greenfield, brownfield, and migration projects:

• Greenfield: /business-analysis starts with structured discovery (users, needs, insights, critical hypotheses) and walks forward through the V-Model.
• Brownfield: /reverse-engineering walks the V backwards over an existing codebase and produces plan-context, ADRs, an arc42 snapshot, a FEATURE inventory, a backlog seed, and an evidence-based BA draft. Every claim is sourced to a file path or doc section. Nothing invented.
• Migration: /dia-migration brings an older DIA project (v1) or a pre-existing V-Model variant up to current conventions: cleans status drift, normalises ID schemas, flattens analysis/, regenerates the backlog as single source of truth.

Innovation methodology, not just automation

The BA and RE agents ship a catalog of 32 innovation methods (qualitative interviews, extreme users, fly on the wall, cultural probes, persona synthesis, stakeholder maps, jobs to be done, brainwriting, TRIZ, wizard of oz, pre-mortem, value proposition quantification, and more) organised as method cards in the docs.

During a BA or RE session, when your answers go thin, the agent stops the interview and proposes the matching field method with a one-page card: what it produces, when to reach for it, how to run it, team and time, things that go wrong, and what to bring back to the session. The actual research work stays human-to-human: interviews with real users, observations in the real context, prototypes on real hands. The agent's job is to spot the gap and pick the right method, not to replace the work.

Quick start

Pick your platform. Each installer drops the same thirteen skills with the same templates and quality gates into your tool of choice.

Claude Code (recommended)

/plugin lives in the Claude Code CLI, not in the VS Code or JetBrains extensions. If claude --version returns command not found, install the CLI first:

curl -fsSL https://claude.ai/install.sh | bash    # official installer
# or: brew install --cask claude-code              # macOS Homebrew
# or: npm install -g @anthropic-ai/claude-code     # any OS with Node

Reopen your shell (source ~/.zshrc or ~/.bashrc), then install the plugin:

/plugin marketplace add https://github.com/pssah4/digital-innovation-agents.git
/plugin install digital-innovation-agents@pssah4-skills

Type / in any new session to see the skills in autocomplete. The dia-bootstrap skill loads automatically at session start as a brief orientation.

VS Code, JetBrains, and Cursor extensions cannot install plugins. Running /plugin marketplace add ... inside the VS Code Claude Code extension returns /plugin isn't available in this environment. Install once through the CLI as above. The skills land under ~/.claude/skills/ and the IDE extension picks them up from the same global directory on the next session start. On Windows without WSL, the CLI is experimental; install through WSL or copy the manually:

The manual install copies the complete plugin bundle (skills, tools, hooks, scripts) under a stable path and symlinks the skills into ~/.claude/skills/. Skills invoke tooling at ${DIA_PLUGIN_ROOT}/tools/..., so DIA_PLUGIN_ROOT is exported from the install location. Re-run the block to update; it pulls the latest commit and rewrites the bundle in place. Skills renamed or removed in newer DIA versions (for example dia-orchestrator from v2) are deleted explicitly so no stale skill folders survive the upgrade.

# Stable plugin location. Override with DIA_PLUGIN_ROOT env if needed.
DIA_PLUGIN_ROOT="${DIA_PLUGIN_ROOT:-$HOME/.local/share/dia-plugin}"

# Clone or update the plugin bundle
if [ -d "$DIA_PLUGIN_ROOT/.git" ]; then
  git -C "$DIA_PLUGIN_ROOT" fetch --tags --prune
  git -C "$DIA_PLUGIN_ROOT" reset --hard origin/main
else
  mkdir -p "$(dirname "$DIA_PLUGIN_ROOT")"
  rm -rf "$DIA_PLUGIN_ROOT"
  git clone https://github.com/pssah4/digital-innovation-agents.git "$DIA_PLUGIN_ROOT"
fi

mkdir -p ~/.claude/skills

# Remove legacy DIA skills that were renamed or dropped
for legacy in dia-orchestrator; do
  rm -rf "$HOME/.claude/skills/$legacy"
done

# Symlink the current DIA skill set (covers future renames automatically)
for skill in project-conventions reverse-engineering business-analysis \
             requirements-engineering architecture coding testing \
             security-audit consistency-check humanizer dia-guide \
             dia-migration dia-setup dia-bootstrap; do
  rm -rf "$HOME/.claude/skills/$skill"
  ln -sfn "$DIA_PLUGIN_ROOT/skills/$skill" "$HOME/.claude/skills/$skill"
done

# Persist DIA_PLUGIN_ROOT so skills can resolve tools/ at runtime
shell_rc="$HOME/.zshrc"
[ -f "$HOME/.bashrc" ] && shell_rc="$HOME/.bashrc"
if ! grep -q "DIA_PLUGIN_ROOT=" "$shell_rc" 2>/dev/null; then
  echo "export DIA_PLUGIN_ROOT=\"$DIA_PLUGIN_ROOT\"" >> "$shell_rc"
fi
export DIA_PLUGIN_ROOT

After the first install, open a new shell so DIA_PLUGIN_ROOT is set, then start claude. Skills resolve their helper scripts at $DIA_PLUGIN_ROOT/tools/... regardless of the user-project cwd.

Cursor

/add-plugin digital-innovation-agents

Or search for "digital-innovation-agents" in the Cursor plugin marketplace.

GitHub Copilot (CLI and VS Code)

GitHub Copilot has no marketplace command. Install by copying the .github/ directory plus the helper tools into your project. The agents call flow.py, anchor.py, the migration scripts, and the consistency check, so tools/ and scripts/ must be available locally.

Re-run the block to update; the source checkout is pulled to the latest commit and each target subfolder is wiped before copy, so no stale Copilot agents, chat modes, or helper scripts survive an upgrade.

# Clone or update the source checkout
if [ -d /tmp/dia/.git ]; then
  git -C /tmp/dia fetch --tags --prune
  git -C /tmp/dia reset --hard origin/main
else
  rm -rf /tmp/dia
  git clone https://github.com/pssah4/digital-innovation-agents.git /tmp/dia
fi

mkdir -p .github

# Wipe old DIA copies before installing the current set
for sub in agents chatmodes instructions templates; do
  rm -rf ".github/$sub"
  cp -r "/tmp/dia/.github/$sub" ".github/$sub"
done
cp /tmp/dia/.github/copilot-instructions.md .github/copilot-instructions.md

# Install the helper tools (flow.py, anchor.py, migration, hooks)
# at the project root so the agents can invoke them
for sub in tools scripts hooks; do
  rm -rf "$sub"
  cp -r "/tmp/dia/$sub" "$sub"
done

# Skills resolve tools/ relative to the project root in this layout,
# so DIA_PLUGIN_ROOT points at the project itself
echo 'export DIA_PLUGIN_ROOT="$(pwd)"' >> .envrc 2>/dev/null || true

The Copilot install brings the helper tools into the project rather than to a global location because Copilot agents run with the project as their working directory and have no plugin-bundle path to fall back on.

Copilot Chat picks the agents up automatically on the next session. In Copilot Chat:

@business-analyst I want to build a tool that helps teams run better retrospectives
@requirements-engineer Here is my BA document, create epics and features
@architect Design the architecture based on the requirements handoff
@developer Implement the first feature
@debugger Tests are failing, analyze the error log

The Copilot agents run the same Exploration / Ideation / Validation cycle, the same templates, and the same quality gates as the Claude Code skills.

Gemini CLI

gemini extensions install https://github.com/pssah4/digital-innovation-agents

To update:

gemini extensions update digital-innovation-agents

Verify the install

Start a session in your chosen platform and try one of these:

/dia-setup                 Activate the workflow in this project
/dia-guide                 Full guided cycle from idea to security audit
/business-analysis         Start a structured business analysis
/reverse-engineering       Brownfield entry for an existing codebase

/dia-setup is the first call in any new project. It asks for the mode (off, git-only, or github-sync), writes .dia/config.toml, and adds a managed anchor block to your existing CLAUDE.md, AGENTS.md, GEMINI.md, .cursorrules, or similar agent files. Re-run any time to change the mode or remove the anchor.

Or ask a natural-language question like "help me analyse this business problem". The agent should invoke the matching skill.

Troubleshooting:

• Claude Code or Cursor: restart the session, the SessionStart hook loads the skill overview automatically.
• Codex: verify the symlink with ls -la ~/.agents/skills/digital-innovation-agents.
• OpenCode: check logs with opencode run --print-logs "hello" 2>&1 | grep -i digital-innovation.
• Gemini CLI: run gemini extensions list.

The skills

The thirteen skills split into three groups: V-Model phase skills (the ten that own a phase or move you between phases), foundation skills (rules and consistency), and the orientation skill (using-digital- innovation-agents loads on session start to introduce the workflow).

V-Model phase skills

Foundation skills

Scope levels

The skills adapt their depth to your project scope. Match the tier to the size of the question.

A Simple Test does not need a stakeholder map. An MVP does not get away without one.

Tech-agnostic requirements

Success Criteria stay free of technology vocabulary. No OAuth, REST, PostgreSQL, or React in the contract between the user and the team. Technical details live in a separate Technical NFRs section and in the ADRs that follow in /architecture. See the Tech-agnostic Requirements page in the docs for the full ruleset.

Living documents

ADRs, features, architecture docs, and the backlog update continuously during implementation. At release time, documentation reflects what was actually built, not what was originally planned. The _devprocess/context/BACKLOG.md file is the single source of truth for project state, and every phase skill touches it in the same edit pass as the code it affects.

Design principles

1. Understand the problem before designing the solution.
2. Separate what the system does (user-observable, tech-free) from how it does it (ADRs, NFRs).
3. Propose the right research method instead of grinding through a question list when your answers go thin.
4. No phase proceeds until its quality gate is met.
5. Every agent reads the real codebase before producing output. The project's CLAUDE.md always takes precedence over generic skill instructions.
