standard

/archcore:standard

Establish a team standard. Creates the full chain: ADR (why this standard) → rule (mandatory behavior) → guide (how to follow it).

When to use

• "Make this a team standard"
• "We need a coding convention for error handling"
• "Standardize how we do API versioning"
• "Create a standard for database migrations"

Not standard:

• Recording a decision without enforcement → /archcore:decide
• Planning a feature → /archcore:plan
• Documenting existing behavior → /archcore:capture
• Reading applicable rules/ADRs/specs before coding → /archcore:context
• Picking up where work left off → /archcore:context

Routing table

Signal	Route	Documents
User wants a new standard (default)	→ full chain	adr → rule → guide
ADR already exists on this topic	→ pick up from rule	rule → guide (link to existing ADR)
User says "just a rule" or "skip the ADR"	→ rule + guide only	rule + guide

Default: full standard-track chain (adr → rule → guide).

Execution

Step 1: Check existing

mcp__archcore__list_documents(types=["adr", "rule", "guide"]) — check what exists on this topic. If ADR exists, skip to rule. If rule exists, skip to guide.

Step 2: Create documents

Skip any documents that already exist on this topic.

ADR (if missing):

• Ask: "What decision led to this standard? What alternatives were considered?"
• Compose content covering Context, Decision, Alternatives Considered, Consequences.
• mcp__archcore__create_document(type="adr")

Rule:

• Ask: "What are the mandatory behaviors? How should this be enforced?"
• Compose content covering Rule (imperative statements), Rationale, Examples (Good/Bad), Enforcement.
• mcp__archcore__create_document(type="rule")
• mcp__archcore__add_relation — rule implements adr

Guide:

• Ask: "What steps should developers follow? What are common pitfalls?"
• Compose content covering Prerequisites, Steps (numbered), Verification, Common Issues.
• mcp__archcore__create_document(type="guide")
• mcp__archcore__add_relation — guide related rule

Step 3: Relate

Suggest mcp__archcore__add_relation calls to link with existing specs, plans, or other standards.

Result

Three linked documents: ADR → rule → guide (rule implements adr, guide related rule). Report: paths, relations, recommended next actions.
