Impl-Strategy Skill

Purpose

Provides implementation strategy and task graph validation for system development. This skill depends on both baseline gate passing and architecture documentation being in place.

Core Functionality

• •Implementation Strategy: Generate and validate implementation plans and task graphs
• •Task Graph Validation: Ensure implementation dependencies are properly defined
• •Strategy Documentation: Create detailed implementation roadmaps
• •Baseline Dependency: Blocked until arch-baseline gate passes

Key Components

Scripts

• •validate_task_graph.py - Main validation script with baseline gate dependency

Resources

• •resources/templates/ - Templates for implementation strategy documents
• •resources/schemas/ - JSON schemas for task graph validation
• •resources/policy/ - Implementation governance policies

Required Documents

Creates and validates implementation artifacts in:

• •docs/implementation/ - Implementation strategy and task graphs
• •docs/baseline/ - Cross-references baseline artifacts
• •docs/architecture/ - Links to architecture documentation

Usage

# Validate implementation strategy (includes baseline gate check)
python custom_skills/impl-strategy/scripts/validate_task_graph.py

Baseline Gate Dependency

This skill requires baseline gate to pass before execution:

• •Calls tools/run_baseline_gate.sh or direct baseline validator
• •If baseline fails: prints "BASELINE GATE FAILED" and exits with code 1
• •Only proceeds with implementation work after baseline validation succeeds

Dependencies

• •Python standard library only
• •Requires baseline gate to pass
• •Expects architecture documentation to exist
• •No network access required

Governance Role

This skill enforces implementation-first governance:

• •Implementation strategy must be documented before coding
• •Task graphs ensure dependency awareness and proper sequencing
• •Blocked until baseline architecture foundation is established

Exit Codes

• •0 - All validations passed
• •1 - Baseline gate failed or implementation strategy validation failed
