Skill Integration Tester

Overview

Validate multi-skill workflows defined in CLAUDE.md (Daily Market Monitoring, Weekly Strategy Review, Earnings Momentum Trading, etc.) by executing each step in sequence. Check inter-skill data contracts for JSON schema compatibility between output of step N and input of step N+1, verify file naming conventions, and report broken handoffs. Supports dry-run mode with synthetic fixtures.

When to Use

After adding or modifying a multi-skill workflow in CLAUDE.md
After changing a skill's output format (JSON schema, file naming)
Before releasing new skills to verify pipeline compatibility
When debugging broken handoffs between consecutive workflow steps
As a CI pre-check for pull requests touching skill scripts

Prerequisites

Python 3.9+
No API keys required
No third-party Python packages required (uses only standard library)

Workflow

Step 1: Run Integration Validation

Execute the validation script against the project's CLAUDE.md:

python3 skills/skill-integration-tester/scripts/validate_workflows.py \
  --output-dir reports/

This parses all **Workflow Name:** blocks from the Multi-Skill Workflows section, resolves each step's display name to a skill directory, and validates existence, contracts, and naming.

Step 2: Validate a Specific Workflow

Target a single workflow by name substring:

python3 skills/skill-integration-tester/scripts/validate_workflows.py \
  --workflow "Earnings Momentum" \
  --output-dir reports/

Step 3: Dry-Run with Synthetic Fixtures

Create synthetic fixture JSON files for each skill's expected output and validate contract compatibility without real data:

python3 skills/skill-integration-tester/scripts/validate_workflows.py \
  --dry-run \
  --output-dir reports/

Fixture files are written to reports/fixtures/ with _fixture flag set.

Step 4: Review Results

Open the generated Markdown report for a human-readable summary, or parse the JSON report for programmatic consumption. Each workflow shows:

Step-by-step skill existence checks
Handoff contract validation (PASS / FAIL / N/A)
File naming convention violations
Overall workflow status (valid / broken / warning)

Step 5: Fix Broken Handoffs

For each FAIL handoff, verify that:

The producer skill's output contains all required fields
The consumer skill's input parameter accepts the producer's output format
File naming patterns are consistent between producer output and consumer input

      "steps": [...],
      "handoffs": [...],

    }
  ]
}

Markdown Report

Structured report with per-workflow sections showing step validation, handoff status, and naming violations.

Reports are saved to reports/ with filenames integration_test_YYYY-MM-DD_HHMMSS.{json,md}.

Resources

scripts/validate_workflows.py -- Main validation script
references/workflow_contracts.md -- Contract definitions and handoff patterns

Key Principles

No API keys required -- all validation is local and offline
Non-destructive -- reads SKILL.md and CLAUDE.md only, never modifies skills
Deterministic -- same inputs always produce same validation results
