Spec-Driven W3 Compliance

Scan for W3 violations (auto-skill chaining without user control) through strict 4-phase workflow with structural anti-skip enforcement.

W3 Definition: Skills/commands that auto-invoke other skills without user approval, causing token overflow and violating lean orchestration principles.

Reference: BRAINSTORM-001 (line 85), STORY-135, ADR-020

If ambiguous or conflicts detected: HALT and use AskUserQuestion

Execution Model

This skill expands inline. After invocation, execute Phase State Initialization immediately. Do not wait passively, ask permission, or offer execution options.

Self-Check (if ANY box is true = VIOLATION):

• Stopping to ask about token budget
• Stopping to offer execution options
• Waiting passively for results
• Asking "should I execute this?"

IF any box checked: EXECUTION MODEL VIOLATION. Go directly to Phase State Initialization now.

Anti-Skip Enforcement Contract

This skill enforces 4 independent anti-skip layers. ALL FOUR must fail for a step to be skipped:

1. Fresh-context reference loading - References loaded fresh from disk each phase, never from memory
2. Binary CLI gates - devforgeai-validate phase-check/phase-complete/phase-record (compiled Rust, cannot be forged by LLM)
3. Hook enforcement - Shell scripts in .claude/hooks/ run outside LLM control
4. Step registry + artifact verification - .claude/hooks/phase-steps-registry.json tracks every mandatory step

Execute-Verify-Record Pattern: Every mandatory step in every phase file has three parts:

• EXECUTE: The exact action to perform
• VERIFY: How to confirm the action happened (Glob, Grep, exit code, variable state)
• RECORD: CLI command to record completion (devforgeai-validate phase-record)

Token Optimization Bias is PROHIBITED. Do not skip, compress, or shortcut any step. Every phase step exists because a previous failure proved it necessary. (Reference: RCA-001, RCA-002)

Parameter Extraction

Extract scan parameters from command context markers set by /audit-w3:

If context markers are not found, use defaults.

Phase State Initialization [MANDATORY FIRST]

devforgeai-validate phase-init W3-AUDIT --workflow=w3-compliance --project-root=.

Phase Orchestration Loop

FOR phase_num in [01, 02, 03, 04]:
    phase_id = phase_num

    1. ENTRY GATE: devforgeai-validate phase-check W3-AUDIT --workflow=w3-compliance --from={prev} --to={phase_id} --project-root=.
       IF exit != 0: HALT

    2. LOAD: Read(file_path="src/claude/skills/spec-driven-w3-compliance/phases/{phase_files[phase_id]}")

    3. EXECUTE: Follow every step in the phase file (EXECUTE-VERIFY-RECORD 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 W3-AUDIT --workflow=w3-compliance --phase={phase_id} --project-root=.

    5. EXIT GATE: devforgeai-validate phase-complete W3-AUDIT --workflow=w3-compliance --phase={phase_id} --checkpoint-passed --project-root=.
       IF exit != 0: HALT

Required Subagents Per Phase

This skill is read-only scanning. No subagents are required.

Deviation Protocol: Any skip requires explicit user consent via AskUserQuestion.

Workflow Completion Validation

IF completed_count < 4: HALT "WORKFLOW INCOMPLETE - {completed_count}/4 phases"
IF completed_count == 4: "All 4 phases completed - W3 compliance audit passed"

Success Criteria

• Detects subagent Skill() invocations (CRITICAL)
• Detects non-orchestration skill auto-chaining (HIGH)
• Flags missing W3 compliance documentation (MEDIUM)
• Identifies auto-invoke language patterns (INFO)
• Excludes legitimate orchestration and backup files
• CRITICAL violations return exit code 1
• Quiet mode works for release integration
• Report format matches other audit commands
