/archcore:capture

Document a module, component, or topic. You describe what needs documenting — the system picks the right document type.

When to use

• "Document the auth module"
• "Capture how the payment system works"
• "Write down the API contract"
• "Create reference docs for the config system"

Not capture:

• Recording a specific decision → /archcore:decide
• Planning a feature → /archcore:plan
• Making something a standard → /archcore:decide
• Reading applicable rules/ADRs/specs before coding → /archcore:context
• Picking up where work left off → /archcore:context

Routing table

Given $ARGUMENTS and conversation context, classify what the user needs:

Signal	Route	Documents
User describes a component contract or interface	→ spec	Single spec
User describes reference material (registry, glossary, lookup)	→ doc	Single doc
User describes how-to instructions or procedures	→ guide	Single guide
User describes a module comprehensively ("document everything about X")	→ adr + spec + guide	Multiple docs with relations
Ambiguous	→ ask one question	"Is this primarily a decision, a technical contract, reference material, or instructions?"

Default: if still unclear after one question, create an adr (the most common documentation need).

Execution

Step 1: Check existing

mcp__archcore__list_documents — scan for existing documents on this topic. Prevent duplicates.

Step 2: Route

Apply the routing table above. If $ARGUMENTS clearly signals a type, proceed. If ambiguous, use AskUserQuestion to ask: "Is this primarily a decision, a technical contract, reference material, or instructions?"

Step 3: Create documents

For each document determined by routing:

If ADR:

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

If spec:

• Ask: "What is the contract surface? What are the key constraints?"
• Compose content covering Purpose, Scope, Subject, Contract Surface, Normative Behavior, Constraints.
• mcp__archcore__create_document(type="spec")

If doc:

• Ask: "What information should this reference contain?"
• Compose content covering Overview, Content (structured sections/tables), Examples.
• mcp__archcore__create_document(type="doc")

If guide:

• Ask: "What task does this guide walk through? What prerequisites exist?"
• Compose content covering Prerequisites, Steps (numbered), Verification, Common Issues.
• mcp__archcore__create_document(type="guide")

Step 4: Relate

After each document, call mcp__archcore__add_relation to link to existing related documents. If multiple documents were created, link them with related.

Result

One or more documents created and linked. Report: which documents, their paths, relations added, and suggested next actions (e.g., "consider adding a rule to codify this decision").
