| 10 | |
| 11 | ``` |
| 12 | UBIQUITOUS: The [system] shall [action]. |
| 13 | EVENT-DRIVEN: WHEN [trigger], the [system] shall [action]. |
| 14 | UNWANTED: IF [condition], the [system] shall [action]. |
| 15 | OPTIONAL: WHERE [feature included], the [system] shall [action]. |
| 16 | COMPLEX: WHILE [state], WHEN [trigger], the [system] shall [action]. |

| 21 | ## Input Processing |
| 22 | |
| 23 | From user's natural language request, extract: |
| 24 | 1. What the system should DO (functional requirements) |
| 25 | 2. What happens when things GO WRONG (error handling) |
| 26 | 3. Performance / scale expectations (non-functional) |
| 27 | 4. What is OUT OF SCOPE (explicit exclusions) |

| 31 | ## spec.md Template |
| 32 | |
| 33 | ```markdown |
| 34 | # SPEC-{ID}: {Title} |
| 35 | |
| 36 | ## Status |
| 37 | - [x] Draft |
| 38 | |
| 39 | ## Summary |
| 40 | {2-3 sentence description} |
| 41 | |
| 42 | ## Scope |
| 43 | In: |
| 44 | - {Included behavior 1} |
| 45 | - {Included behavior 2} |
| 46 | |
| 47 | Out: |
| 48 | - {Explicit exclusion 1} |
| 49 | - {Explicit exclusion 2} |
| 50 | |
| 51 | ## Requirements |
| 52 | |
| 53 | ### Functional |
| 54 | - FR-01: WHEN user submits valid credentials, the system shall authenticate and create session. |
| 55 | - FR-02: IF credentials are invalid, the system shall return 401 with message "Invalid credentials". |
| 56 | - FR-03: IF user is not authenticated, the system shall redirect to /login. |
| 57 | - FR-04: WHEN session expires, the system shall automatically refresh if refresh token is valid. |
| 58 | - FR-05: WHEN user clicks logout, the system shall invalidate session and clear cookie. |
| 59 | |
| 60 | ### Non-Functional |
| 61 | - NFR-01: The system shall respond to login requests within 500ms (p99). |
| 62 | - NFR-02: The system shall support 1000 concurrent sessions. |
| 63 | |
| 64 | ## Dependencies |
| 65 | - External: bcrypt, jsonwebtoken |
| 66 | - Internal: UserRepository, SessionRepository |
| 67 | |
| 68 | ## Open Questions |
| 69 | - [ ] Should we support SSO/OAuth in this SPEC or separate? |
| 70 | - [ ] Session duration: 24h? 7d? Configurable? |
| 71 | ``` |

| 75 | ## acceptance.md Template |
| 76 | |
| 77 | ```markdown |
| 78 | # Acceptance Criteria: SPEC-{ID} |
| 79 | |
| 80 | ## AC-01: Successful Login |
| 81 | **Given** a registered user with valid email and password |
| 82 | **When** POST /api/auth/login with correct credentials |
| 83 | **Then** response is 200 OK |
| 84 | **And** session cookie is set with HttpOnly and SameSite=Strict flags |
| 85 | **And** response body contains user.id and user.email |
| 86 | |
| 87 | ## AC-02: Failed Login — Wrong Password |
| 88 | **Given** a registered user |
| 89 | **When** POST /api/auth/login with wrong password |
| 90 | **Then** response is 401 Unauthorized |
| 91 | **And** response body is { success: false, error: "Invalid credentials" } |
| 92 | **And** no session cookie is set |
| 93 | |
| 94 | ## AC-03: Failed Login — Unknown Email |
| 95 | **Given** no user with the provided email exists |
| 96 | **When** POST /api/auth/login |
| 97 | **Then** response is 401 (same as wrong password — no user enumeration) |
| 98 | |
| 99 | ## AC-04: Authenticated Route Protection |
| 100 | **Given** no session cookie present |
| 101 | **When** GET /api/protected-resource |
| 102 | **Then** response is 401 Unauthorized |
| 103 | |
| 104 | ## AC-05: Session Expiry |
| 105 | **Given** an active session |
| 106 | **When** session token expires |
| 107 | **Then** the system attempts silent refresh using refresh token |
| 108 | **And** if refresh token also expired, returns 401 |
| 109 | |
| 110 | ## AC-06: Logout |
| 111 | **Given** an authenticated user |
| 112 | **When** POST /api/auth/logout |
| 113 | **Then** session cookie is cleared (Max-Age=0) |
| 114 | **And** session is invalidated server-side |
| 115 | ``` |
| 116 | |

| 118 | |
| 119 | ## ID Assignment |
| 120 | |
| 121 | Before creating spec, check existing specs: |
| 122 | ```bash |
| 123 | ls .autopus/specs/ | grep "SPEC-" | sort -V | tail -1 |
| 124 | # → SPEC-042-... → next ID is SPEC-043 |
| 125 | ``` |
| 126 | |
| 127 | If no specs exist, start at SPEC-001. |
| 128 | |
| 129 | --- |
| 130 | |
| 131 | ## Output |
| 132 | |
| 133 | Creates directory and files: |
| 134 | ``` |
| 135 | .autopus/specs/SPEC-{ID}-{slug}/ |
| 136 | ├── spec.md ← created by spec-writer |
| 137 | ├── acceptance.md ← created by spec-writer |
| 138 | ├── plan.md ← created by planner (later) |
| 139 | └── research.md ← created by Phase 1.8 (later) |

| 144 | ## Spec Writer Complete |
| 145 | |
| 146 | Created: .autopus/specs/SPEC-043-user-authentication/ |
| 147 | ✅ spec.md (6 functional + 2 non-functional requirements) |
| 148 | ✅ acceptance.md (6 acceptance criteria, AC-01 through AC-06) |
| 149 | |
| 150 | Open Questions (need answers before implementation): |
| 151 | 1. Session duration default? |
| 152 | 2. SSO scope — this SPEC or separate? |
| 153 | |
| 154 | Next steps: |
| 155 | /aura spec:implement SPEC-043 → Run full pipeline |
| 156 | /aura plan: SPEC-043 → Planning only |
