/spec — Relentless Specification Workflow
What
Converts an idea into a written, versioned specification that both the developer and Claude explicitly agree on — before any planning or code. The contract:
- Never assume. Every gap in the idea becomes a question. If Claude catches
itself thinking "probably", "presumably", or "the usual way" — that thought is a question to ask, not a decision to make.
- Relentless, but structured. Questions come in focused rounds (3–5 at a
time) across nine dimensions — not one overwhelming dump, and not a single polite round that stops early.
- Agreement is explicit. Specs have a status lifecycle: Draft → In Review →
Approved. Implementation never starts from a Draft. Approval requires the developer to read the final document and say so.
- Specs are files, not chat. Output persists to
docs/specs/<NNN>-<slug>.md
and survives the session. Plans, tests, and commits reference it.
When
- Any feature too big to describe completely in one sentence
- New product or module ideas ("I want to add team workspaces")
- Before
/planfor non-trivial features — plan consumes the approved spec - When requirements feel fuzzy mid-implementation: stop,
/spec, re-plan - Trigger phrases: "spec", "requirements", "PRD", "define the feature", "acceptance criteria"
Skip for: bug fixes, refactors, single-endpoint CRUD where the entity is obvious.
How
Step 1: Capture and Restate
Take the raw idea and restate it in one paragraph: what Claude understood, in its own words. End with: "Is this the idea? What did I get wrong?" Do not begin questioning until the developer confirms the restatement — questioning the wrong idea wastes everyone's time.
Step 2: Questioning Rounds
Work through the nine dimensions in order. Each round: pick the 3–5 most load-bearing unanswered questions (answers that reshape later questions come first). Where the harness supports selectable options, present choices with trade-offs — and a recommendation — but the developer chooses; a recommendation is never silently applied.
| # | Dimension | What to pin down |
|---|---|---|
| 1 | Problem & users | Who hurts today, how they work around it, what success looks like |
| 2 | Scope | What is IN this iteration, what is explicitly OUT, where the MVP line sits |
| 3 | Domain & data | Entities, relationships, lifecycle (create→archive→delete?), retention |
| 4 | API contract | Resources, endpoints, request/response shapes, pagination, versioning |
| 5 | Authorization | Who can do what, role/claim model, tenant boundaries |
| 6 | Edge cases & failure modes | Concurrency, duplicates, idempotency, partial failure, limits |
| 7 | Non-functionals | Expected volume, latency budget, growth assumptions |
| 8 | Integrations | External services, published events, webhooks, side effects |
| 9 | Acceptance criteria | Testable Given/When/Then for every behavior in scope |
Rules of relentless questioning:
- Record every answer in the draft spec immediately — answers are requirements, not conversation.
- Challenge contradictions on the spot: "In round 1 you said X; this answer implies not-X. Which wins?"
- "I don't know" is a legal answer → moves to Deferred Decisions with an explicit
fallback the developer chooses now ("default to soft-delete until decided"). Silent deferral is forbidden.
- A dimension is done when a follow-up round generates zero new questions for it.
- The questioning phase is done when ALL nine dimensions are done. Do not stop
because the conversation feels long — stopping early is how assumptions sneak in.
Step 3: Draft the Spec File
Determine the next number from existing files in docs/specs/ (create the directory if missing). Write docs/specs/<NNN>-<slug>.md:
# Spec NNN: <Title>
**Status:** Draft
**Date:** <today>
## Problem <!-- who hurts, why now -->
## Scope <!-- ### In / ### Out — both explicit -->
## Domain Model <!-- entities, relationships, lifecycle -->
## API Contract <!-- endpoints table: verb, route, request, response, errors -->
## Authorization <!-- who can do what -->
## Edge Cases & Failure Modes
## Non-Functional Requirements
## Integrations
## Acceptance Criteria <!-- Given/When/Then, numbered AC-1, AC-2, ... -->
## Deferred Decisions <!-- decision, chosen fallback, revisit trigger -->
## Open Questions <!-- MUST be empty before approval -->Step 4: Review Loop
Set status to In Review. Present the complete spec and ask: "Read this end-to-end. What is wrong, missing, or over-engineered?" Fold corrections in and re-present. Repeat until the developer has no further changes. New answers may spawn new questions — that is the process working, not a failure to converge.
Step 5: The Agreement Gate
Approval is a deliberate act, never inferred from silence or "looks good" in passing. Ask explicitly: "Do you approve this spec? After approval, code follows the spec — changes go through the spec first." On approval, set **Status:** Approved (<date>).
- Open Questions must be empty. If any remain, the spec cannot be approved — resolve or defer each one explicitly.
- If implementation later reveals a wrong assumption: stop, set status back to
In Review, fix the spec with the developer, then resume. Code never silently diverges from an approved spec.
Step 6: Handoff
/planreads the approved spec and maps acceptance criteria to implementation steps/tddturns acceptance criteria into the first failing tests (AC-n → test name)- Commits for the feature reference the spec:
feat: team workspaces (spec 004)
Example
User: /spec users should be able to invite teammates
Claude: Here's what I understood: an existing user can invite another person
to join their... workspace? account? That's already my first gap.
Is this the idea? What did I get wrong?
User: yes, invite to their organization
Claude: Round 1 — Scope & Users:
1. Can invitees be people without an existing account, or only registered users?
2. Who can invite — any member, or only admins/owners?
3. Is there a limit on pending invites (per org, per plan)?
4. Out of scope check: bulk invites and SSO-provisioned members — both OUT for now?
User: 1: both. 2: admins only. 3: no limit. 4: correct, both out.
Claude: Round 2 — Edge cases (your "both" in Q1 raises these):
1. Inviting an email that already has a pending invite — error, or resend?
2. Invite expiry — 7 days, 30 days, never?
3. Invitee already belongs to another org — multi-org membership or rejection?
...
[…rounds continue until all nine dimensions are exhausted…]
Claude: Spec written to docs/specs/004-team-invitations.md (In Review).
Read it end-to-end. What is wrong, missing, or over-engineered?
User: looks right. approved.
Claude: Status: Approved (2026-06-12). Next: /plan to map AC-1..AC-9
to implementation steps.Related
/plan— Consumes the approved spec; never plan a spec-worthy feature without one/tdd— Acceptance criteria become the first failing tests/scaffold— Generates the slices the plan calls forarchitecture-advisor— Load during Step 2 if the feature forces architectural decisions
