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

Getting summary

python .claude/skills/state-management/scripts/read_state.py --format summary

Output:

Pipeline: abc123
Started: 2024-01-15 10:30:00

Gates:
  1. lint-test:      PASS (45s)
  2. coverage:       PASS (32s)
  3. cross-platform: RUNNING
  4. python-matrix:  PENDING
  5. security:       PENDING
  6. api-compat:     PENDING
  7. packaging:      PENDING
  8. github-pr:      PENDING
