Agent Skills: SPEC Workflow Management

SPEC Workflow Management

Quick Reference

SPEC Workflow Orchestration using GEARS notation (current) — backed by the EARS legacy backward-compatibility window — for systematic requirement definition and Plan-Run-Sync workflow integration.

Lint behavior canonicalized per the GEARS migration policy.

Core Capabilities:

• GEARS-Format Specifications (current): Five requirement patterns with the unified compound clause [Where ...][While ...][When ...] The <subject> shall <behavior> and a generalized <subject> (any noun, not only "the system")
• EARS Legacy Reference: All EARS patterns preserved for 6 months from v3.0.0 release to keep the 88 pre-v3 SPECs readable
• Requirement Clarification: Four-step systematic process with assumption analysis
• SPEC Document Templates: Standardized 3-file structure (spec.md / plan.md / acceptance.md)
• Plan-Run-Sync Integration: Seamless workflow connection
• Parallel Development: Git Worktree-based SPEC isolation
• Quality Gates: TRUST 5 framework validation

GEARS Five Patterns (current notation):

| Pattern | GEARS form (current) | EARS form (legacy) | Notes | |---------|----------------------|--------------------|-------| | Ubiquitous | "The <subject> shall <behavior>" | "The system shall <behavior>" | <subject> may be any noun: system, component, service, agent, function, artifact | | Event-driven | "When <event-detected>, the <subject> shall <behavior>" | "WHEN <event>, the system shall <action>" | Unchanged trigger semantics | | State-driven | "While <state>, the <subject> shall <behavior>" | "WHILE <state>, the system shall <action>" | Unchanged — promoted as a first-class pattern | | Capability gate | "Where <capability / feature flag / static config>, the <subject> shall <behavior>" | "WHERE <feature exists>, the system shall <action>" | Reframed — represents capability gate / feature flag / static config (no longer "Optional") | | Event-detected (replaces IF/THEN) | "When <undesired-condition-detected>, the <subject> shall <response>" | IF <condition> THEN <action> [DEPRECATED — use WHEN <event-detected>] | The IF/THEN modality was removed; describe the same intent as a detected event |

Unified compound clause: **Where** <precondition> **While** <state> **When** <event> the <subject> shall <behavior> — any subset of the three modifiers may chain.

See GEARS notation reference.

IF/THEN deprecated callout: Authoring guidance previously used IF <condition> THEN <action> to describe state-conditioned behavior. In GEARS that intent is expressed as When <condition-detected> (event-detected form). The lint engine emits a LegacyEARSKeyword warning (non-strict) or error (moai spec lint --strict) on residual IF/THEN in new SPECs. The 6-month backward-compatibility window remains active for legacy SPECs.

Generalized subject substitution: GEARS replaces the hardcoded "the system" subject with <subject>, which may be any noun. Authors writing NEW SPECs MAY use the generalized form. Examples of valid non-"the system" subjects:

• "The skill shall present GEARS as the primary notation." (Ubiquitous, <subject> = skill)
• "The agent shall return a blocker report instead of prompting the user." (Ubiquitous, <subject> = agent)
• "When a SPEC author opens the file, the component shall display the deprecation banner." (Event-driven, <subject> = component)

The 88 existing SPECs keep "The system" as the default subject for readability; existing readers do not need to relearn the canonical phrase.

EARS Five Patterns (legacy — 6-month backward-compatibility window):

| Pattern | Format | Use | |---------|--------|-----| | Ubiquitous | "The system shall always X" | Always active | | Event-Driven | "WHEN event THEN action" | Trigger-response | | State-Driven | "WHILE state, the system shall ..." | Conditional behavior (use WHILE, not legacy IF/THEN) | | Unwanted | "The system shall not X" | Prohibition | | Optional | "Where possible, provide X" | Nice-to-have |

The legacy IF/THEN modality is replaced by GEARS When <event-detected> — see callout above.

When to Use:

• Feature planning and requirement definition
• SPEC document creation and maintenance
• Parallel feature development coordination
• Quality assurance and validation planning
• Requirements gathering from user story narratives

Quick Commands:

/moai:1-plan "user authentication system"                   # Create new SPEC
/moai:1-plan "login" "signup" --worktree                    # Parallel SPECs
/moai:1-plan "payment processing" --branch                  # New branch
/moai:1-plan SPEC-001 "add OAuth support"                   # Update existing

Implementation Guide

Core Concepts

SPEC-First Development Philosophy:

• EARS format ensures unambiguous requirements
• Requirement clarification prevents scope creep
• Systematic validation through test scenarios
• Integration with DDD workflow for implementation
• Quality gates enforce completion criteria
• Constitution reference ensures project-wide consistency

Constitution Reference (SDD 2025 Standard)

Constitution defines the project DNA that all SPECs must respect. Before creating any SPEC, verify alignment with .moai/project/tech.md.

Constitution Components: Technology Stack, Naming Conventions, Forbidden Libraries, Architectural Patterns, Security Standards, Logging Standards.

Constitution Verification: All SPEC technology choices align with Constitution stack versions, no forbidden libraries, naming conventions respected, architectural boundaries preserved.

WHY: Constitution prevents architectural drift and ensures maintainability.

SPEC Workflow Stages

| Stage | Activity | |-------|----------| | 1 | User Input Analysis — parse natural-language feature description | | 2 | Requirement Clarification — 4-step systematic process | | 3 | EARS Pattern Application — structure requirements using five patterns | | 4 | Success Criteria Definition — establish completion metrics | | 5 | Test Scenario Generation — create verification test cases | | 6 | SPEC Document Generation — produce standardized markdown |

GEARS Format (current)

GEARS (Generalized EARS) is the canonical SPEC notation as of v3.0.0. It preserves Ubiquitous / When (event-driven) / While (state-driven) and reframes Where as a capability gate. The legacy IF/THEN modality is replaced by When <event-detected>.

GEARS notation is exhaustively described in docs-site GEARS notation reference and the canonical GEARS migration policy record.

Compound clause example (with non-"the system" subject):

Where the project is initialized While strict mode is active When a SPEC author runs moai spec lint, the lint engine shall emit a LegacyEARSKeyword finding for every residual IF/THEN modality.

This example chains all three GEARS modifiers (Where, While, When) and uses <subject> = "lint engine" rather than "the system".

EARS Format (legacy — 6-month backward-compatibility window)

Five patterns cover all requirement types. Each pattern has a specific use case and test strategy. The 88 existing SPECs continue to use EARS notation and are valid for 6 months from the v3.0.0 release per the lint engine's backward-compatibility policy.

See EARS deep dive with examples per pattern for use cases, examples, and test strategies for Ubiquitous, Event-Driven, State-Driven, Unwanted, and Optional requirements.

Requirement Clarification Process

5-step systematic process:

• Step 0: Assumption Analysis (Philosopher Framework) — surface technical, business, team, integration assumptions
• Step 0.5: Root Cause Analysis (Five Whys) — surface problem to root cause for problem-driven SPECs
• Step 1: Scope Definition — supported methods, validation rules, failure handling, session management
• Step 2: Constraint Extraction — performance, security, compatibility, scalability
• Step 3: Success Criteria — coverage targets, response time percentiles, functional completion, quality gates
• Step 4: Test Scenario Creation — normal, error, edge, security cases

See requirement clarification detailed workflow for assumption documentation templates and Five Whys application.

Plan-Run-Sync Workflow Integration

PLAN (/moai:1-plan): manager-spec analyzes input → EARS requirements → clarification → SPEC creation in .moai/specs/ → optional --branch or --worktree.

RUN (/moai:2-run): manager-develop loads SPEC → ANALYZE-PRESERVE-IMPROVE (DDD) or RED-GREEN-REFACTOR (TDD) per quality.yaml constitution.development_mode → moai-workflow-testing reference → per-spawn Agent(general-purpose) domain delegation → quality-gate validation (Stop hook / /moai gate).

SYNC (/moai:3-sync): manager-docs synchronizes documentation → API docs from SPEC → README and architecture updates → CHANGELOG → version control commit.

Parallel Development with Git Worktree

Worktree provides isolated working directories per SPEC for parallel development without branch switching. Benefits: parallel development, clear ownership boundaries, dependency isolation, risk reduction.

See worktree workflow patterns for creation commands and team collaboration examples.

Resources

SPEC File Organization

Standard 3-File Format:

• .moai/specs/SPEC-{ID}/spec.md — EARS format specification
• .moai/specs/SPEC-{ID}/plan.md — implementation plan, milestones, technical approach
• .moai/specs/SPEC-{ID}/acceptance.md — acceptance criteria, Given-When-Then scenarios

[HARD] Every SPEC directory MUST contain all 3 files. Missing files create incomplete requirements.

State files: .moai/state/last-session-state.json. Generated docs: .moai/docs/api-documentation.md.

SPEC Metadata Schema

Canonical 12 required fields (enforced by the SPEC frontmatter lint rule): id, title, version, status, created, updated, author, priority, phase, module, lifecycle, tags.

Status enum (8 values): draft → planned → in-progress → implemented → completed | superseded | archived | rejected.

Optional fields: issue_number, depends_on, lint.skip, bc_id, tier (S/M/L LEAN tier).

Full schema at .claude/rules/moai/development/spec-frontmatter-schema.md (SSOT).

SPEC Lifecycle Management

Three lifecycle levels:

| Level | Description | Maintenance | |-------|-------------|-------------| | spec-first | SPEC discarded after implementation | None | | spec-anchored | SPEC maintained alongside implementation | Quarterly review | | spec-as-source | SPEC is single source of truth, only SPEC edited by humans | Changes regenerate impl |

Transitions: spec-first → spec-anchored when production-critical, spec-anchored → spec-as-source when compliance or regeneration workflow required. Downgrade requires explicit justification.

Quality Metrics

SPEC Quality Indicators: requirement clarity (all EARS patterns used), test coverage (all requirements have scenarios), constraint completeness, success criteria measurability.

Validation Checklist: All EARS requirements testable, no ambiguous language ("should", "might", "usually"), all error cases documented, performance targets quantified, security requirements OWASP-compliant.

Token Management

| Phase | Token Budget | |-------|--------------| | PLAN | ~30% | | RUN | ~60% | | SYNC | ~10% |

Context Optimization: SPEC document persists in .moai/specs/. Session state in .moai/state/. Minimal context transfer through SPEC ID reference. Agent delegation reduces token overhead.

SPEC Scope and Classification

What Belongs in .moai/specs/

The .moai/specs/ directory is EXCLUSIVELY for SPEC documents that define features to be implemented.

Valid SPEC Content: feature requirements in EARS format, implementation plans with milestones, acceptance criteria with Given/When/Then scenarios, technical specifications for new functionality, user stories with clear deliverables.

SPEC Characteristics: forward-looking (what WILL be built), actionable, testable, structured (EARS).

What Does NOT Belong in .moai/specs/

| Document Type | Why Not SPEC | Correct Location | |---------------|--------------|------------------| | Security Audit | Analyzes existing code | .moai/reports/security-audit-{DATE}/ | | Performance Report | Documents current metrics | .moai/reports/performance-{DATE}/ | | Dependency Analysis | Reviews existing dependencies | .moai/reports/dependency-review-{DATE}/ | | Architecture Overview | Documents current state | .moai/docs/architecture.md | | API Reference | Documents existing APIs | .moai/docs/api-reference.md | | Meeting Notes | Records decisions made | .moai/reports/meeting-{DATE}/ | | Retrospective | Analyzes past work | .moai/reports/retro-{DATE}/ |

Out of Scope Classification Rules

These routing rules decide what is out of scope for a SPEC document (and where it belongs instead). When authoring a SPEC's own exclusions section, express each excluded item as a ### Out of Scope — <topic> H3 sub-heading with - bullets so the section satisfies the OutOfScopeRule lint.

[HARD] Reports analyze what EXISTS → .moai/reports/. SPECs define what will be BUILT → .moai/specs/.

[HARD] Documentation explains HOW TO USE → .moai/docs/. SPECs define WHAT TO BUILD → .moai/specs/.

Common Rationalizations

| Rationalization | Reality | |---|---| | "The SPEC is obvious, I can skip EARS format" | EARS exists because obvious requirements are the first to be misinterpreted. The format forces disambiguation. | | "Acceptance criteria are redundant with the requirements" | Requirements describe intent. Acceptance criteria describe observable evidence. Both are needed. | | "I will refine the SPEC during implementation" | Late refinement means wasted implementation. SPEC is the cheap place to change your mind. | | "Research is a nice-to-have, not a blocker" | Skipping research produces SPECs that conflict with existing code. research.md prevents rework. | | "Annotation cycle is just user friction" | Annotation catches misunderstandings before code is written. It is the cheapest feedback loop in the pipeline. | | "This SPEC is small, I do not need a separate file" | Every SPEC is a persistent contract. In-message SPECs cannot be referenced by /moai run SPEC-XXX. |

Red Flags

• Requirements written in imperative prose instead of EARS (WHEN X, SHALL Y)
• Acceptance criteria phrased as subjective judgments ("feels fast", "looks clean")
• SPEC document missing research.md sibling when modifying existing code
• Annotation cycle skipped or reduced to a single-turn "looks good"
• Requirements use "should" where they mean "shall" (optional vs mandatory ambiguity)
• SPEC-ID not registered in .moai/specs/ directory

Verification

• [ ] SPEC file exists at .moai/specs/SPEC-XXX/spec.md with unique ID
• [ ] Every requirement uses EARS keywords (WHEN, WHILE, WHERE, IF, SHALL)
• [ ] Every acceptance criterion is observable (test output, file existence, metric threshold)
• [ ] research.md exists when the SPEC touches existing code
• [ ] Annotation cycle completed with explicit user approval marker
• [ ] SPEC references existing SPEC-IDs it depends on or supersedes
• [ ] Out of Scope section present to prevent scope creep — at least one ### Out of Scope — <topic> H3 sub-heading with a - bullet entry (satisfies the OutOfScopeRule lint)
