spec-driven-lifecycle

name	spec-driven-lifecycle
description	Coordinates spec-driven development lifecycle from Epic -> Sprint -> Story -> Architecture -> Development -> QA -> Release with structural anti-skip enforcement. Manages story lifecycle across 11 workflow states, enforces 4 quality gates, and orchestrates skill invocation. Replaces spec-driven-lifecycle as the unified lifecycle coordinator. Use when starting sprints, managing story workflow progression, auditing deferrals, running sprint retrospectives, or coordinating multi-story releases. Always use this skill when /orchestrate, /create-sprint, or /audit-deferrals is invoked.

Spec-Driven Lifecycle

Coordinate the complete story lifecycle from Backlog through Released, enforcing quality gates at every transition and invoking specialized skills at the right time.

Context files are THE LAW: tech-stack.md, source-tree/, dependencies.md, coding-standards.md, architecture-constraints.md, anti-patterns.md

If ambiguous or conflicts detected: HALT and use AskUserQuestion

Anti-Skip Enforcement Contract

Enforced structurally outside LLM control, not by this prose — by the framework's deterministic gates wired for this workflow: the devforgeai-validate phase gates, the settings.json-registered .claude/hooks/ scripts, and .claude/hooks/phase-steps-registry.json (ADR-076).

Parameter Extraction

Extract parameters from conversation context. See references/parameter-extraction.md for the extraction algorithm.

Command Integration

Context Marker	Set By	Description
$STORY_ID	/orchestrate	Story identifier (STORY-NNN)
**Operation:** plan-sprint	/create-sprint	Sprint planning mode trigger
**Command:** audit-deferrals	/audit-deferrals	Audit deferrals mode trigger
**Sprint Name:** {name}	/create-sprint	Sprint name for planning
**Selected Stories:** {ids}	/create-sprint	Story IDs for sprint
**Duration:** {days} days	/create-sprint	Sprint duration
**Start Date:** {date}	/create-sprint	Sprint start date
**Epic:** {id}	/create-sprint	Epic linkage
**Auto-Resume:** Enabled	/orchestrate	Checkpoint resume flag

---

Phase State Initialization [MANDATORY FIRST]

devforgeai-validate phase-init ${STORY_ID} --project-root=.

Exit Code	Meaning	Action
0	New workflow	State file created. Set CURRENT_PHASE = "01".
1	Existing workflow	Resume. Run devforgeai-validate phase-status ${STORY_ID} to get CURRENT_PHASE.
2	Invalid story ID	HALT. Must match STORY-XXX pattern.
127	CLI not installed	Continue without enforcement (backward compatibility).

Iteration counter: iteration_count = 1, max_iterations = 5. If resuming, read from phase-state.json.

Note: For Sprint Planning and Audit Deferrals modes, use a synthetic ID (e.g., SPRINT-{name} or AUDIT-{timestamp}) if no story ID is available.

---

Mode Router [MANDATORY - AFTER Phase State Initialization]

Detect operating mode from conversation context markers. Mode determines which phases execute.

Priority order: Sprint > Audit > Story > Default (first match wins)

1. IF "**Operation:** plan-sprint" found in conversation:
   MODE = "sprint-planning"
   PHASE_SEQUENCE = [01, 03S, 08]
   Display: "Mode: Sprint Planning"

2. ELSE IF "**Command:** audit-deferrals" found in conversation:
   MODE = "audit-deferrals"
   PHASE_SEQUENCE = [01, 03A, 04A, 08]
   Display: "Mode: Audit Deferrals"

3. ELSE IF "**Story ID:** STORY-NNN" found in conversation:
   MODE = "story-management"
   PHASE_SEQUENCE = [01, 02, 03, 04, 05, 06, 07, 08]
   Display: "Mode: Story Management"

4. ELSE:
   MODE = "default"
   Read references/mode-detection.md for inference logic.
   IF inference fails:
     HALT with AskUserQuestion:
       Question: "Cannot determine operating mode. What would you like to do?"
       Header: "Mode"
       Options:
         - label: "Orchestrate a story"
           description: "Manage story lifecycle (dev -> QA -> release)"
         - label: "Plan a sprint"
           description: "Create a sprint with story selection"
         - label: "Audit deferrals"
           description: "Audit deferred work in completed stories"
       multiSelect: false

See references/mode-detection.md for complete detection algorithm and edge cases.

Phase Orchestration Loop

FOR phase_id in PHASE_SEQUENCE:

    1. ENTRY GATE: devforgeai-validate phase-check ${STORY_ID} --from={prev} --to={phase_id}
       IF exit != 0: HALT

    2. LOAD: Read(file_path="phases/{phase_files[phase_id]}")

    3. EXECUTE: Follow every step in the phase file (EXECUTE-VERIFY-GATE triplets)
       - Each step's EXECUTE instruction tells you exactly what to do
       - Each step's VERIFY instruction tells you how to confirm it happened
       - Each step's RECORD instruction tells you what CLI command to call

    4. RECORD: devforgeai-validate phase-record ${STORY_ID} --phase={phase_id} --subagent={name}

    5. EXIT GATE: devforgeai-validate phase-complete ${STORY_ID} --phase={phase_id} --checkpoint-passed
       IF exit != 0: HALT

Workflow States

Stories progress through 11 sequential states:

Backlog -> Architecture -> Ready for Dev -> In Development -> Dev Complete ->
QA In Progress -> [QA Approved | QA Failed] -> Releasing -> Released

See references/workflow-states.md for complete state definitions. See references/state-transitions.md for valid transitions, prerequisites, and quality gate requirements.

---

Quality Gate Enforcement

Four gates block workflow progression when requirements not met:

Gate	Transition	Key Requirements
Gate 1: Context Validation	Architecture -> Ready for Dev	6 context files present and valid
Gate 2: Test Passing	Dev Complete -> QA In Progress	All tests pass, coverage 95%/85%/80%
Gate 3: QA Approval	QA Approved -> Releasing	All ACs verified, no unresolved deferrals
Gate 4: Release Readiness	Releasing -> Released	Smoke tests pass, rollback plan documented

See references/quality-gates.md for complete gate requirements and enforcement logic.

Workflow Completion Validation

Story Management mode:
  IF completed_count < 8: HALT "WORKFLOW INCOMPLETE - {completed_count}/8 phases"
  IF completed_count == 8: "All 8 phases completed - Workflow validation passed"

Sprint Planning mode:
  IF completed_count < 3: HALT "WORKFLOW INCOMPLETE - {completed_count}/3 phases"

Audit Deferrals mode:
  IF completed_count < 4: HALT "WORKFLOW INCOMPLETE - {completed_count}/4 phases"

IF iteration_count >= 4: Display "Approaching limit" IF iteration_count >= max_iterations: HALT "Maximum iterations reached"

---

Common Issues

Top 5 issues and quick solutions:

1. Mode detection fails - Check context markers match expected format (see references/mode-detection.md)
2. Checkpoint not detected - Verify Status History format in story file (see references/workflow-states.md)
3. Quality gate blocks - Review gate requirements for the specific transition (see references/quality-gates.md)
4. QA retry exceeds 3 - Address root cause, consider splitting story (see phase-06-qa-retry.md)
5. Sprint capacity exceeded - Remove lower-priority stories or adjust capacity (see phase-03S-sprint-planning.md)
