name: state-management description: Pipeline state management for tracking gate progress, prerequisites, and results. Used by all gate agents to coordinate pipeline execution.

State Management Skill

Scripts for reading and writing pipeline state, checking prerequisites, and initializing pipelines.

Scripts

init_pipeline.py

Initialize a new pipeline run.

python .claude/skills/state-management/scripts/init_pipeline.py [--target-package NAME] [--target-version VERSION]

Creates a new pipeline_state.json with fresh UUID and timestamps.

read_state.py

Get current pipeline state.

python .claude/skills/state-management/scripts/read_state.py [--gate GATE_NAME] [--format json|summary]

Options:

• --gate: Get status of specific gate only
• --format: Output format (default: json)

write_state.py

Update gate status after execution.

python .claude/skills/state-management/scripts/write_state.py <gate> <PASS|FAIL> [--details JSON]

Arguments:

• gate: Gate name (e.g., lint-test, coverage)
• status: PASS or FAIL
• --details: JSON string with gate-specific details

check_prerequisites.py

Verify prerequisites for a gate.

python .claude/skills/state-management/scripts/check_prerequisites.py <gate>

Returns:

• Exit code 0: Prerequisites met, gate can run
• Exit code 1: Prerequisites NOT met, lists blocking gates

Usage Examples

Starting a new pipeline

# Initialize
python .claude/skills/state-management/scripts/init_pipeline.py --target-package mylib --target-version 1.0.0

# Check status
python .claude/skills/state-management/scripts/read_state.py

Running a gate

# Check if gate can run
python .claude/skills/state-management/scripts/check_prerequisites.py coverage
if [ $? -eq 0 ]; then
    # Run the gate...
    python .claude/skills/state-management/scripts/write_state.py coverage PASS --details '{"total_coverage": 87.3}'
fi
