Execution

Phase 1: Task Discovery

Objective: Parse task assignment from orchestrator message.

Source	Required	Description
Orchestrator message	Yes	Contains task ID (DRAFT-NNN), session folder, doc type

Steps:

1. Extract session folder from task message (Session: <path>)
2. Extract task ID (DRAFT-NNN pattern)
3. Determine document type from task subject

Output: session-folder, task-id, doc-type.

---

Phase 2: Context & Discussion Loading

Objective: Load all required inputs for document generation.

Document Type Routing Table

Task	Doc Type	Template	Prior Discussion Input	Output Path
DRAFT-001	product-brief	templates/product-brief.md	DISCUSS-001-discussion.md	spec/product-brief.md
DRAFT-002	requirements	templates/requirements-prd.md	DISCUSS-002-discussion.md	spec/requirements/_index.md
DRAFT-003	architecture	templates/architecture-doc.md	DISCUSS-003-discussion.md	spec/architecture/_index.md
DRAFT-004	epics	templates/epics-template.md	DISCUSS-004-discussion.md	spec/epics/_index.md

Inline Discuss Mapping

Doc Type	Inline Discuss Round	Perspectives
product-brief	DISCUSS-002	product, technical, quality, coverage
requirements	DISCUSS-003	quality, product, coverage
architecture	DISCUSS-004	technical, risk
epics	DISCUSS-005	product, technical, quality, coverage

Progressive Dependency Loading

Doc Type	Requires
product-brief	discovery-context.json
requirements	discovery-context.json + product-brief.md
architecture	discovery-context.json + product-brief.md + requirements/_index.md
epics	discovery-context.json + product-brief.md + requirements/_index.md + architecture/_index.md

Steps:

1. Read document-standards.md for formatting rules
2. Read template for this doc type from routing table
3. Read spec-config.json and discovery-context.json
4. Read prior discussion feedback (if file exists)
5. Read all progressive dependencies for this doc type

Failure handling:

Condition	Action
Template not found	Error, report missing template path
Prior doc not found	Report to orchestrator, request prerequisite completion
Discussion file missing	Proceed without discussion feedback

Output: Template loaded, prior discussion feedback (or null), prior docs loaded, spec-config ready.

---

Phase 3: Document Generation

Objective: Generate document using template and multi-CLI analysis.

Shared Context Block

Built from spec-config and discovery-context for all CLI prompts:

SEED: <topic>
PROBLEM: <problem-statement>
TARGET USERS: <target-users>
DOMAIN: <domain>
CONSTRAINTS: <constraints>
FOCUS AREAS: <focus-areas>
CODEBASE CONTEXT: <existing-patterns, tech-stack> (if codebase context exists)

---

DRAFT-001: Product Brief

Strategy: 3-way parallel CLI analysis, then synthesize.

Perspective	CLI Tool	Focus
Product	gemini	Vision, market fit, success metrics, scope
Technical	codex	Feasibility, constraints, integration complexity
User	claude	Personas, journey maps, pain points, UX

CLI call template (one per perspective, all run in background):

ccw cli -p "PURPOSE: <perspective> analysis for specification.
<shared-context>
TASK: <perspective-specific-tasks>
MODE: analysis
EXPECTED: <structured-output>
CONSTRAINTS: <perspective-scope>" --tool <tool> --mode analysis

Perspective-specific task details:

Perspective	Task Focus
Product (gemini)	Define product vision, identify market positioning, set measurable success metrics, define MVP scope boundaries
Technical (codex)	Assess technical feasibility of each goal, identify integration constraints, estimate complexity per feature, flag technical risks
User (claude)	Build user personas with demographics and motivations, map user journeys, identify pain points and friction, propose UX principles

Synthesis flow (after all 3 CLIs return):

3 CLI outputs received
  +-- Identify convergent themes (2+ perspectives agree)
  +-- Identify conflicts (e.g., product wants X, technical says infeasible)
  +-- Extract unique insights per perspective
  +-- Integrate discussion feedback from DISCUSS-001 (if exists)
  +-- Fill template sections -> Write to spec/product-brief.md

Template sections: Vision, Problem Statement, Target Users, Goals, Scope, Success Criteria, Assumptions.

---

DRAFT-002: Requirements/PRD

Strategy: Single CLI expansion, then structure into individual requirement files.

Step	Tool	Action
1	gemini	Generate functional (REQ-NNN) and non-functional (NFR-type-NNN) requirements
2	(local)	Integrate discussion feedback from DISCUSS-002
3	(local)	Write individual files + _index.md

CLI prompt focus: For each product-brief goal, generate 3-7 functional requirements with user stories, acceptance criteria, and MoSCoW priority. Generate NFR categories: performance, security, scalability, usability.

ccw cli -p "PURPOSE: Generate comprehensive requirements from product brief.
<shared-context>
PRODUCT BRIEF: <product-brief-content>
TASK: * For each goal generate 3-7 functional requirements with user stories and acceptance criteria
* Assign MoSCoW priority (Must/Should/Could/Wont)
* Generate NFR categories: performance, security, scalability, usability
* Each requirement has: id, title, priority, user_story, acceptance_criteria[]
MODE: analysis
EXPECTED: JSON with functional_requirements[] and non_functional_requirements[]
CONSTRAINTS: Requirements must be testable and specific" --tool gemini --mode analysis

Output structure:

spec/requirements/
  +-- _index.md           (summary table + MoSCoW breakdown)
  +-- REQ-001-<slug>.md   (individual functional requirement)
  +-- REQ-002-<slug>.md
  +-- NFR-perf-001-<slug>.md  (non-functional)
  +-- NFR-sec-001-<slug>.md

Each requirement file has: YAML frontmatter (id, title, priority, status, traces), description, user story, acceptance criteria.

---

DRAFT-003: Architecture

Strategy: 2-stage CLI (design + critical review).

Stage	Tool	Purpose
1	gemini	Architecture design: style, components, tech stack, ADRs, data model, security
2	codex	Critical review: challenge ADRs, identify bottlenecks, rate quality 1-5

Stage 2 runs AFTER stage 1 completes (sequential dependency).

Stage 1 CLI:

ccw cli -p "PURPOSE: Design system architecture from requirements.
<shared-context>
REQUIREMENTS: <requirements-index-content>
TASK: * Select architecture style with justification
* Define component breakdown with responsibilities
* Recommend tech stack with rationale
* Create ADRs for key decisions
* Design data model
* Define API contract patterns
* Address security architecture
MODE: analysis
EXPECTED: JSON with architecture_style, components[], tech_stack{}, adrs[], data_model, api_patterns, security
CONSTRAINTS: Must trace back to requirements" --tool gemini --mode analysis

Stage 2 CLI (receives Stage 1 output):

ccw cli -p "PURPOSE: Critical architecture review.
ARCHITECTURE PROPOSAL: <stage-1-output>
TASK: * Challenge each ADR with alternatives
* Identify performance bottlenecks
* Assess scalability limits
* Rate overall quality 1-5
* Suggest improvements
MODE: analysis
EXPECTED: JSON with adr_reviews[], bottlenecks[], scalability_assessment, quality_rating, improvements[]
CONSTRAINTS: Be critical, identify weaknesses" --tool codex --mode analysis

After both complete:

1. Integrate discussion feedback from DISCUSS-003
2. Map codebase integration points (from discovery-context.relevant_files)
3. Write individual ADR files + _index.md

Output structure:

spec/architecture/
  +-- _index.md           (overview, component diagram, tech stack, data model, API, security)
  +-- ADR-001-<slug>.md   (individual decision record)
  +-- ADR-002-<slug>.md

Each ADR file has: YAML frontmatter (id, title, status, traces), context, decision, alternatives with pros/cons, consequences, review feedback.

---

DRAFT-004: Epics & Stories

Strategy: Single CLI decomposition, then structure into individual epic files.

Step	Tool	Action
1	gemini	Decompose requirements into 3-7 Epics with Stories, dependency map, MVP subset
2	(local)	Integrate discussion feedback from DISCUSS-004
3	(local)	Write individual EPIC files + _index.md

CLI prompt focus:

ccw cli -p "PURPOSE: Decompose requirements into implementable epics and stories.
<shared-context>
REQUIREMENTS: <requirements-index-content>
ARCHITECTURE: <architecture-index-content>
TASK: * Group requirements by domain into 3-7 Epics
* Each Epic has STORY-EPIC-NNN children with user stories and acceptance criteria
* Define MVP subset (mark which epics/stories are MVP)
* Create Mermaid dependency diagram between epics
* Recommend execution order considering dependencies
* Estimate T-shirt size per epic (S/M/L/XL)
MODE: analysis
EXPECTED: JSON with epics[], dependency_graph, mvp_scope[], execution_order[]
CONSTRAINTS: Stories must be estimable and independently deliverable" --tool gemini --mode analysis

Output structure:

spec/epics/
  +-- _index.md               (overview table, dependency map, execution order, MVP scope)
  +-- EPIC-001-<slug>.md      (individual epic with stories)
  +-- EPIC-002-<slug>.md

Each epic file has: YAML frontmatter (id, title, priority, mvp, size, requirements, architecture, dependencies), stories with user stories and acceptance criteria.

All generated documents include YAML frontmatter: session_id, phase, document_type, status=draft, generated_at, version, dependencies.

---

Phase 4: Self-Validation + Inline Discuss

4a: Self-Validation

Check	What to Verify
has_frontmatter	Document starts with valid YAML frontmatter
sections_complete	All template sections present in output
cross_references	session_id matches spec-config
discussion_integrated	Prior round feedback reflected (if feedback exists)
files_written	All expected files exist (individual + _index.md)

Validation decision table:

Outcome	Action
All checks pass	Proceed to 4b (Inline Discuss)
Non-critical issues	Fix issues, re-validate, then proceed to 4b
Critical failure (missing template, no CLI output)	Report error in output, skip 4b

4b: Inline Discuss

After validation, spawn discuss subagent (Pattern 2.8) for this task's discuss round:

const critic = spawn_agent({
  message: `### MANDATORY FIRST STEPS
1. Read: ~/.codex/skills/team-lifecycle/agents/discuss-agent.md

## Multi-Perspective Critique: <DISCUSS-NNN>

### Input
- Artifact: <output-path>
- Round: <DISCUSS-NNN>
- Perspectives: <perspectives-from-inline-discuss-mapping>
- Session: <session-folder>
- Discovery Context: <session-folder>/spec/discovery-context.json
`
})
const result = wait({ ids: [critic], timeout_ms: 120000 })
close_agent({ id: critic })

Round-to-perspective mapping (use the Inline Discuss Mapping table from Phase 2):

Doc Type	Round	Perspectives to pass
product-brief	DISCUSS-002	product, technical, quality, coverage
requirements	DISCUSS-003	quality, product, coverage
architecture	DISCUSS-004	technical, risk
epics	DISCUSS-005	product, technical, quality, coverage

Discuss result handling:

Verdict	Severity	Action
consensus_reached	-	Include action items in report, proceed to output
consensus_blocked	HIGH	Flag in output with structured consensus_blocked format for orchestrator. Do NOT self-revise.
consensus_blocked	MEDIUM	Include warning in output. Proceed to output normally.
consensus_blocked	LOW	Treat as consensus_reached with notes.

consensus_blocked output format:

[writer] <task-id> complete. Discuss <DISCUSS-NNN>: consensus_blocked (severity=<severity>)
Divergences: <top-3-divergent-points>
Action items: <prioritized-items>
Recommendation: <revise|proceed-with-caution|escalate>
Artifact: <output-path>
Discussion: <session-folder>/discussions/<DISCUSS-NNN>-discussion.md

---

Inline Subagent Calls

This agent spawns the discuss subagent during Phase 4b:

Discuss Subagent (Phase 4b)

When: After self-validation of generated document Agent File: ~/.codex/skills/team-lifecycle/agents/discuss-agent.md Pattern: 2.8 (Inline Subagent)

See Phase 4b code block above. The round ID and perspectives vary per doc type -- use the Inline Discuss Mapping table.

Result Handling

Result	Severity	Action
consensus_reached	-	Integrate action items into report, continue
consensus_blocked	HIGH	Include in output with severity flag for orchestrator. Do NOT self-revise -- orchestrator creates revision task.
consensus_blocked	MEDIUM	Include warning, continue
consensus_blocked	LOW	Treat as reached with notes
Timeout/Error	-	Continue without discuss result, log warning in output

---
