Run Quality Gate

Execute validation commands as quality gates with configurable blocking/non-blocking behavior and structured error reporting.

When to Use

• Type-check validation in pre-flight or quality gates
• Build validation before releases
• Test execution as quality gate
• Lint validation for code quality
• Custom validation commands
• Orchestrator phase validation
• Worker self-validation

Instructions

Step 1: Receive Gate Configuration

Accept gate configuration as input.

Expected Input:

{
  "gate": "type-check|build|tests|lint|custom",
  "blocking": true,
  "custom_command": "pnpm custom-validate"
}

Parameters:

• gate: Type of quality gate to run (required)
• blocking: Whether failure should stop workflow (default: true)
• custom_command: Command to run when gate="custom" (required for custom gates)

Step 2: Map Gate to Command

Determine command to execute based on gate type.

Gate Commands:

• type-check → pnpm type-check
• build → pnpm build
• tests → pnpm test
• lint → pnpm lint
• custom → Use custom_command parameter

Validation:

• If gate="custom", custom_command must be provided
• Command must be valid shell command

Step 3: Execute Command

Run command via Bash tool with timeout.

Execution Parameters:

• Timeout: 300000ms (5 minutes)
• Capture stdout and stderr
• Record exit code
• Track execution duration

Tools Used: Bash

Step 4: Parse Exit Code and Output

Determine if gate passed based on exit code.

Pass/Fail Logic:

• Exit code 0 → Passed
• Exit code non-zero → Failed

Extract Errors: Look for error patterns in output:

• Lines containing "error"
• Lines containing "failed"
• Lines containing "✗"
• TypeScript error codes (TS####)
• Stack traces

Step 5: Determine Action

Calculate action based on result and blocking flag.

Action Logic:

IF exit_code == 0:
  action = "continue"
  passed = true
ELSE:
  IF blocking == true:
    action = "stop"
  ELSE:
    action = "warn"
  passed = false

Step 6: Return Structured Result

Return complete quality gate result.

Expected Output:

{
  "gate": "type-check",
  "passed": true,
  "blocking": true,
  "action": "continue",
  "errors": [],
  "exit_code": 0,
  "duration_ms": 2345,
  "command": "pnpm type-check",
  "timestamp": "2025-10-18T14:30:00Z"
}

Output Fields:

• gate: Gate type that was run
• passed: Whether gate passed (boolean)
• blocking: Whether gate was blocking
• action: Action to take (continue|stop|warn)
• errors: Array of error messages extracted
• exit_code: Command exit code
• duration_ms: Execution time in milliseconds
• command: Actual command executed
• timestamp: ISO-8601 timestamp of execution

Error Handling

• Timeout (5 minutes): Return failed with timeout error
• Missing custom_command: Return error requesting custom_command
• Invalid gate type: Return error listing valid gates
• Command not found: Return failed with command not found error
• Empty output but non-zero exit: Return failed with generic error

  "command": "pnpm type-check",
  "timestamp": "2025-10-18T14:30:00Z"
}

Example 2: Blocking Build that Fails (Should Stop)

Input:

{
  "gate": "build",
  "blocking": true
}

Command Output:

$ pnpm build
✗ Build failed
ERROR in src/app.ts
Module not found: Error: Can't resolve 'missing-module'
exit code: 1

Output:

{
  "gate": "build",
  "passed": false,
  "blocking": true,
  "action": "stop",
  "errors": ["ERROR in src/app.ts", "Module not found: Error: Can't resolve 'missing-module'"],
  "exit_code": 1,
  "duration_ms": 5432,
  "command": "pnpm build",
  "timestamp": "2025-10-18T14:30:05Z"
}

Example 3: Non-Blocking Lint that Fails (Should Warn)

Input:

{
  "gate": "lint",
  "blocking": false
}

Command Output:

$ pnpm lint
✗ 12 problems (8 errors, 4 warnings)
src/utils.ts:10:5 - error - Missing semicolon
src/app.ts:25:1 - warning - Prefer const over let
exit code: 1

Output:

{
  "gate": "lint",
  "passed": false,
  "blocking": false,
  "action": "warn",
  "errors": [
    "src/utils.ts:10:5 - error - Missing semicolon",
    "src/app.ts:25:1 - warning - Prefer const over let"
  ],
  "exit_code": 1,

Validation

• Maps all standard gate types to correct commands
• Executes commands with 5 minute timeout
• Captures exit code correctly
• Extracts errors from output
• Determines action correctly based on blocking flag
• Records execution duration
• Handles timeout gracefully
• Validates custom_command when gate="custom"
• Returns structured JSON output

Integration with Agents

Orchestrator Usage

## Quality Gate: Type Check

Use run-quality-gate Skill with gate="type-check" and blocking=true.

If action="stop", halt workflow and report failure.
If action="continue", proceed to next phase.

Worker Self-Validation

## Step 5: Self-Validation

Use run-quality-gate Skill to validate changes:

1. Run type-check (blocking=true)
2. Run build (blocking=true)
3. Run tests (blocking=false)

If any blocking gate returns action="stop", rollback changes.

Quality Gates Orchestrator

## Phase 2: Execute Quality Gates

For each gate in [type-check, build, tests, lint]:
result = run-quality-gate(gate, blocking=true)

if result.action == "stop":
HALT and report failure

if result.action == "warn":
LOG warning and continue

Notes

• Timeout is fixed at 5 minutes to prevent indefinite hangs
• Error extraction is best-effort (may not capture all errors)
• Custom commands must be valid shell commands
• Exit code 0 always means success regardless of output
• Non-zero exit code always means failure
• Blocking flag only affects action, not passed status
