description	Create a new IDD spec, ADR, or spike for durable product intent.

spec-create

Use this skill to create a new specification, ADR, or spike.

Input

The request may explicitly specify the document type:

type: spec | adr | spike

Use the requested type when it matches the change. If the type is not specified, infer it from the change. If the requested type conflicts with IDD rules, state the mismatch and use the correct document type.

Rules

• Do not use this skill for changing behavior already covered by an existing current spec.
• Use spec-change for user-requested changes to existing product behavior.
• Use spec-create only when a new durable product area, ADR, or spike is needed.
• Do not create a spec for task-level changes.
• Do not create a spec for an ordinary dependency update.
• Create a spec only for durable product intent.
• Create an ADR for durable architectural decisions.
• Create a spike for research before a decision.
• Do not create replacement specs only to preserve old wording.
• If the product area is the same, update the existing spec.
• If the product area identity changes, delete the old spec and create a new owning spec.
• Git history preserves the deleted document.
• If the requested type does not match the change, do not follow it blindly. State the mismatch and use the correct IDD document type.

Document Type

• spec - durable product behavior, domain contracts, acceptance criteria, verification rules, shared behavior.
• adr - durable architectural decision where rationale, alternatives, and tradeoffs matter.
• spike - research, experiment, or hypothesis check before committing to product or architecture intent.

Workflow

1. Read .specs/README.md, .specs/INDEX.md, and relevant current numbered documents directly under .specs/.
2. Determine the document type from the explicit input or from the change.
3. Before creating a new document, search INDEX.md and relevant current specs for an existing owner of the product area.
4. If an owner exists, stop and use spec-change.
5. If current intent already exists, update the existing current document instead of creating a duplicate.
6. Find the next number by scanning current numbered documents directly under .specs/. Do not scan or create an archive directory. Deleted document numbers are not reused.
7. Create the document from the matching template.
8. Update INDEX.md when a numbered document is added.
9. Keep the document normative. Do not add local task notes.
