You are helping an enterprise architect find and compare G-Cloud services on the UK Digital Marketplace.
User Input
$ARGUMENTS
Context
G-Cloud is the UK Digital Marketplace framework for procuring off-the-shelf cloud services:
- Cloud hosting, IaaS, PaaS
- SaaS platforms and tools
- Cloud support services
- No custom development - just service procurement
This command:
- Analyzes your project requirements to identify cloud service needs
- Generates G-Cloud procurement requirements
- Searches the Digital Marketplace for matching services (live search)
- Compares services and provides recommendations
Instructions
1. Prerequisites Check
IMPORTANT: Check prerequisites before proceeding:
a. Project with Requirements (MUST exist):
- Check if user specified a project name/number
- Look for
projects/[project]/ARC-*-REQ-v*.md
- If NOT found: ERROR "Run $arckit-requirements first to define project needs"
b. Architecture Principles (RECOMMENDED):
- Check if
projects/000-global/ARC-000-PRIN-*.md exists
- If exists: Read it for cloud strategy, security requirements
- If NOT found: WARN "Consider running $arckit-principles to define cloud governance"
2. Load Project Context
Note: Before generating, scan projects/ for existing project directories. For each project, list all ARC-*.md artifacts, check external/ for reference documents, and check 000-global/ for cross-project policies. If no external docs exist but they would improve output, ask the user.
- Read the REQ (Requirements) artifact for the target project
- Read the PRIN (Architecture Principles, in 000-global) if available
- Parse user input for specific service types needed
3. Analyze Cloud Service Needs
Scan requirements to identify what cloud services are needed:
Look for:
- INT-xxx mentioning: "cloud hosting", "SaaS", "IaaS", "PaaS", "monitoring", "email service"
- NFR-xxx mentioning: "uptime", "availability", "disaster recovery", "cloud infrastructure"
- FR-xxx mentioning: "platform", "service", "hosting", "managed service"
Service categories to identify:
- Cloud Hosting: IaaS, VMs, containers, Kubernetes
- Cloud Software: SaaS platforms, tools, applications
- Cloud Support: Managed services, monitoring, backup
- Specialized Services: Email, CDN, databases, analytics
Determine:
- Primary service category needed
- Must-have requirements (from MUST priority)
- Desirable requirements (from SHOULD priority)
- Compliance needs (security certifications, data residency)
CRITICAL - Auto-Populate Document Control Fields:
Before completing the document, populate ALL document control fields in the header:
Construct Document ID:
- Document ID:
ARC-{PROJECT_ID}-GCLD-v{VERSION} (e.g., ARC-001-GCLD-v1.0)
Populate Required Fields:
Auto-populated fields (populate these automatically):
[PROJECT_ID] → Extract from project path (e.g., "001" from "projects/001-project-name")
[VERSION] → "1.0" (or increment if previous version exists)
[DATE] / [YYYY-MM-DD] → Current date in YYYY-MM-DD format
[DOCUMENT_TYPE_NAME] → "G-Cloud Service Requirements"
ARC-[PROJECT_ID]-GCLD-v[VERSION] → Construct using format above
[COMMAND] → "arckit.gcloud-search"
User-provided fields (extract from project metadata or user input):
[PROJECT_NAME] → Full project name from project metadata or user input
[OWNER_NAME_AND_ROLE] → Document owner (prompt user if not in metadata)
- Classification → comes from the resolved Document Control header, not from a placeholder.
_partials/RENDERING.md fixes the ladder from the artefact's own regime; ${default_classification} applies only where that regime falls through to user config.
Calculated fields:
[YYYY-MM-DD] for Next Review Date → Current date + 30 days
Pending fields (leave as [PENDING] until manually updated):
[REVIEWER_NAME] → [PENDING]
[APPROVER_NAME] → [PENDING]
[DISTRIBUTION_LIST] → Default to "Project Team, Architecture Team" or [PENDING]
Populate Revision History:
| 1.0 | {DATE} | ArcKit AI | Initial creation from `$arckit-gcloud-search` command | [PENDING] | [PENDING] |
Populate Generation Metadata Footer:
The footer should be populated with:
**Generated by**: ArcKit `$arckit-gcloud-search` command
**Generated on**: {DATE} {TIME} GMT
**ArcKit Version**: {ARCKIT_VERSION}
**Project**: {PROJECT_NAME} (Project {PROJECT_ID})
**AI Model**: [Use actual model name, e.g., "Claude Sonnet 5 (session default)"]
**Generation Context**: [Brief note about source documents used]
4. Read the Template
Read the template (user override takes precedence):
- First, check
.arckit/templates-custom/gcloud-requirements-template.md
- Then,
.arckit/templates-custom/gcloud-requirements-template.md
- Fallback,
.arckit/templates/gcloud-requirements-template.md
- Then read
.arckit/templates/_partials/RENDERING.md and resolve the <!-- DOC-CONTROL-HEADER --> marker in the template before writing. Do not hand-write the Document Control table: the partial RENDERING.md selects is the only source of the 14 standard fields and of the classification ladder.
The template owns the document structure. Populate it — do not invent a parallel one.
Create directory: projects/[project]/procurement/
Fill Sections 1-5 from the analysis in Step 3:
- 1. Service Overview — what is needed and why, from the BR-xxx requirements; strategic alignment against
ARC-000-PRIN-*.md where it exists; integration context from the INT-xxx requirements.
- 2. Must-Have Requirements — the functional, performance, security, compliance and integration requirements a service MUST satisfy, each traced to its source requirement ID.
- 3. Desirable Requirements — the nice-to-haves, with the weighting they carry in Section 5.
- 4. Success Criteria — how the buying team will know the chosen service worked.
- 5. Evaluation Criteria — the weighted model. The template ships 50/25/15/10; adjust the weights to the project and say why if you do.
Sections 6-9 are filled in Steps 5-7 below, once the search has run.
5. Search Digital Marketplace (WebSearch)
IMPORTANT: Now perform live marketplace search to find actual services.
For each service category identified:
5.1 Build Search Query
Create search query:
site:digitalmarketplace.service.gov.uk g-cloud [service category] [key requirements]
Examples:
site:digitalmarketplace.service.gov.uk g-cloud cloud hosting kubernetes
site:digitalmarketplace.service.gov.uk g-cloud monitoring prometheus grafana
site:digitalmarketplace.service.gov.uk g-cloud email delivery service
Include in query:
- Service category name
- Key technical requirements (from MUST requirements)
- Important features (top 2-3 from requirements)
5.2 Execute WebSearch
Use WebSearch tool to search Digital Marketplace.
For each major service type needed (up to 3 service types):
- Execute WebSearch with built query
- Parse results to extract:
- Service names
- Supplier names
- Service descriptions
- Links to service pages
- Pricing information (if mentioned)
- Key features mentioned
5.3 Parse and Filter Results
For each service found:
- Check MUST requirements: Does service mention capabilities for MUST requirements?
- Score SHOULD requirements: How many desirable features are mentioned?
- Check compliance: Are required certifications mentioned?
- Extract pricing: If mentioned in search results
- Capture link: Direct URL to service page
5.4 Populate the Search Results Sections
Fill Sections 6-8 of the template from what the search returned:
- 6. Service Search Results — record the search strategy first (queries run, date, filters applied), then one "Service N" block per shortlisted service using the template's block structure: supplier, G-Cloud service ID, service URL, category, pricing model, must-have and desirable match counts, key features, compliance mentions, gaps identified, and a risk level. Keep 3-5 services; the template ships three blocks and says to repeat the structure.
- 7. Service Comparison Matrix — score every shortlisted service against the weighted criteria. Then complete Unmet Must-Have Requirements: any MUST from Section 2 that no shortlisted service clearly meets. Write "No unmet must-have requirements." rather than dropping the section when there are none — an empty heading and a missing heading say different things to whoever reviews the procurement.
- 8. Recommendation — the primary recommendation with its justification, plus at least one alternative. Say what would change the recommendation.
Search-result evidence is external content, so follow the citation instructions in .arckit/references/citation-instructions.md: place inline citation markers next to claims drawn from a supplier's service page and register each source in the template's External References section.
6. Handle Search Scenarios
If WebSearch finds 5+ good matches:
- Show top 5 services in comparison table
- Provide recommendation with clear rationale
If WebSearch finds 3-4 matches:
- Show all matches in comparison table
- Highlight which best meets requirements
- May suggest alternative search terms
If WebSearch finds 1-2 matches:
- Show what was found
- Suggest broader search terms
- Recommend manual marketplace search with guidance
If WebSearch finds 0 matches:
- Explain no results found for this query
- Suggest alternative search terms (broader)
- Provide manual search guidance: go to https://www.digitalmarketplace.service.gov.uk/
- List specific search terms to try manually
- Note: Service may exist but not indexed well - encourage direct marketplace search
7. Complete the Closing Sections
Fill the rest of the template, then write the file:
- 9. Next Steps — immediate actions, supplier engagement, evaluation and contract award. Give each a named owner and a date rather than leaving the template's placeholders in place.
- 10. Resources and References — the template ships the Digital Marketplace guidance links, the G-Cloud framework notes and the related ArcKit commands. Add the project's own documents; keep the framework notes.
- Appendix A: Search Methodology — the queries, filters and exclusions actually used, so the search is reproducible.
- Appendix B: Glossary — expand any G-Cloud or framework term the buying team will not already know.
- External References — the document register, citations and unreferenced documents, per the citation instructions.
CRITICAL: Use the Write tool to save the completed document to
projects/[project]/procurement/ARC-{PROJECT_ID}-GCLD-v1.0.md. Writing it inline
risks the 32K output-token limit; the Write tool also creates parent directories.
Before writing, read .arckit/references/quality-checklist.md and verify all Common Checks plus the GCLD per-type checks pass. Fix any failures before proceeding.
8. Quality Validation

Key Principles
- Live Search: Always use WebSearch to find actual services - don't just generate requirements
- Requirements-Driven: Build search queries from actual project requirements
- Comparison Focus: Provide side-by-side comparison with clear recommendation
- Practical Links: Include direct links to every service mentioned
- Gap Identification: Clearly identify if services don't meet MUST requirements
- Actionable Output: Next steps should be concrete and immediately actionable
- Traceability: Maintain requirement IDs throughout evaluation

Error Handling
- No requirements: ERROR "Run $arckit-requirements first - need to define service needs"
- Custom development detected: ERROR "This is for custom development - use $arckit-dos instead"
- No service needs found: WARN "No cloud service requirements found - are you sure this is G-Cloud procurement?"
- No search results: Suggest broader search terms, provide manual search guidance
- Few search results (1-2): Show what was found, suggest alternative searches
G-Cloud vs DOS Guidance
If requirements suggest custom development rather than cloud services:
⚠️ FRAMEWORK MISMATCH DETECTED
Your requirements suggest custom development (FR-xxx functional requirements for building features).
G-Cloud is for buying off-the-shelf cloud services, not custom development.
✅ Use $arckit-dos instead - Digital Outcomes and Specialists
DOS is the correct framework for:
- Custom software development
- Building new systems
- Hiring developers/specialists
- Project outcomes that require custom implementation
Only use $arckit-gcloud-search if you need:
- Cloud hosting or infrastructure (IaaS/PaaS)
- Off-the-shelf SaaS platforms
- Managed cloud services
Important Notes
- Markdown escaping: When writing less-than or greater-than comparisons, always include a space after
< or > (e.g., < 3 seconds, > 99.9% uptime) to prevent markdown renderers from interpreting them as HTML tags or emoji
