domain-collab

A coordination step for requirements that affect two or more business domains, such as billing and user accounts. It sends the requirement to domain-specific reviewers and checks their combined analysis.

In plain words
What is it for?
Use it for cross-domain changes after the risk classifier routes them, provided the project’s domain registry and shared rules are available.
Why use it?
It helps reveal rules and dependencies that a single-domain review could miss.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

domain-collab scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Domain Collab — Multi-Domain Collaboration Analysis

Accepts natural language requirements spanning 2+ domains, dispatches domain-specific Agents in parallel for analysis, and outputs a structured report after Coordinator cross-validation.

Output language: Read ecw.ymlproject.output_language. All artifact headings, table headers, and labels follow this language. Pass output_language value to every dispatched agent prompt.

Announce at start: "Using ecw:domain-collab to coordinate multi-domain requirement analysis."

Prerequisites

  1. Read the file specified by ecw.yml paths.domain_registry (default .claude/ecw/routing/domain-registry.md) to get domain definitions
  2. Confirm cross-domain-rules.md exists under ecw.yml paths.knowledge_shared
  3. Risk level and domain list are injected from session-state by the auto-continue hook

Knowledge file robustness: If domain-registry.md does not exist, halt and notify user: "Domain registry not found. Run /ecw-init to initialize." If cross-domain-rules.md does not exist, log [Warning: cross-domain-rules.md not found, Round 3 cross-validation will be degraded] and continue — Round 3 §3c will skip rule validation for missing files.

Workflow Overview

For a visual overview of the process, see ./workflow-diagram.md.

Phases: Domain Identification → Round 1 (Independent Analysis, parallel) → Round 2 (Inter-Domain Negotiation, parallel) → Round 3 (Coordinator Cross-Validation) → Output Report.

Phase 1: Domain Identification

  1. Read keywords from project CLAUDE.md domain routing section (keyword→domain mapping table), match against user input, identify involved domains
  2. Read matched domain metadata from domain-registry (knowledge directory, code directory, etc.)
  3. Determine applicability:
    • 0 domains matched → Prompt user: "Cannot identify involved business domains. Please add more description or specify domain names"
    • 1 domain matched → Prompt: "Single-domain requirement — suggest using /requirements-elicitation. This skill focuses on multi-domain collaboration analysis"
    • 2+ domains matched → Proceed with collaboration analysis
  4. If called by risk-classifier with domain list already provided, skip confirmation and execute directly.
  5. If manually triggered (/domain-collab), confirm with user: "Identified domains: {domain list}. Will proceed with multi-domain collaboration analysis."

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

domain-collab is a skill published in the GitHub repository Aimeerrhythm/enterprise-change-workflow (1 stars, last pushed 3mo ago), licensed MIT. It adds 48 tokens to every session and 1,912 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
