Verification Sweep

Verification Sweep

Algorithm for verifying task completion by running verification commands and updating plan status.

Purpose

Verification sweep establishes ground truth about task completion:

• Run verification commands to prove tasks are done
• Update plan file with accurate statuses
• Detect regressions in previously complete tasks
• Report what work remains

When to Use

Perform verification sweep:

• At the start of /tommymorgan:work (before doing any work)
• When running /tommymorgan:status
• After returning from a break or new session
• Before reporting completion status

Algorithm

Step 1: Load Plan File

Read the plan file and extract all tasks:

For each line matching "### \d+\. ":
  - task_number = extracted number
  - task_description = text after number
  - verify_command = content of next **Verify**: `...`
  - current_status = value after **Status**:

Step 2: Run Verification Commands

For each task, execute its verification command:

<verify_command>
echo "Exit code: $?"

Capture:

• Exit code (0 = success)
• Stdout/stderr (for debugging)

Step 3: Determine New Status

Apply status transition rules:

Regression handling: If a previously complete task now fails, warn but do not change status:

WARNING: Regression detected in task N: <description>
Verification command failed but task marked complete.
Investigate before continuing.

Step 4: Update Plan File

For each status change, update the plan file:

Find:

**Status**: pending

Replace with:

**Status**: complete

Use precise edits - only change the status value, preserve everything else.

Step 5: Generate Report

After verification sweep, report results:

## Verification Sweep: <plan filename>

**Run at**: <timestamp>
**Progress**: X/Y tasks complete

### Results
- Task 1: <description> - PASS (complete)
- Task 2: <description> - PASS (complete)
- Task 3: <description> - FAIL (pending)
- Task 4: <description> - SKIP (blocked)

### Summary
- Complete: X
- Pending: Y
- Blocked: Z
- Regressions: N

**Next task**: <first pending task description>

Verification Command Best Practices

Good verification commands:

# Run specific test file
pnpm test src/models/user.test.ts

# Run test with specific pattern
pytest -k test_user_registration

# Check file exists with content
grep -q "export class User" src/models/user.ts

# Verify build succeeds
pnpm build && test -f dist/index.js

Bad verification commands:

# Too broad - might pass for wrong reasons
pnpm test

# Non-deterministic
curl http://localhost:3000/health

# Requires manual inspection
cat src/models/user.ts

Handling Edge Cases

Missing Verification Command

If a task lacks a verification command:

ERROR: Task N has no verification command.
Cannot determine completion status.

Mark as pending and flag for human attention.

Verification Command Timeout

Set reasonable timeout (30 seconds default):

timeout 30 <verify_command>

If timeout:

• Treat as failure
• Log timeout warning
• Consider if command is appropriate

Environment Dependencies

Before running verification commands:

• Ensure test environment is ready
• Check required services are running
• Verify dependencies are installed

If environment issue detected, report clearly:

ERROR: Verification environment not ready.
Missing: <dependency>
Run: <setup command>

Status Transitions

                    ┌─────────────┐
        ┌──────────►│   pending   │◄──────────┐
        │           └──────┬──────┘           │
        │                  │                  │
   (verify fails)    (verify passes)    (unblock)
        │                  │                  │
        │           ┌──────▼──────┐           │
        └───────────│  complete   │───────────┘
                    └──────┬──────┘      │
                           │             │
                    (manual block)       │
                           │             │
                    ┌──────▼──────┐      │
                    │   blocked   ├──────┘
                    └─────────────┘

Transitions:

• pending → complete: Verification passes
• pending → blocked: Manual intervention (with root cause)
• complete → blocked: Manual intervention (regression)
• blocked → complete: Verification passes after unblock
• blocked → pending: Manual unblock

Integration with Commands

/tommymorgan:status

Runs verification sweep and reports results. Does not perform any work.

/tommymorgan:work

Runs verification sweep first, then works on pending tasks:

1. Verification sweep
2. If all complete → done
3. If blocked and no pending → report and stop
4. If pending → work on next task
5. After each task completion → mini-sweep (verify just that task)

Troubleshooting

All tasks show as pending:

• Check verification commands are correct
• Ensure test files exist
• Verify test runner is configured

Complete tasks regressing:

• Check for test pollution between runs
• Verify test isolation
• Look for environment-dependent tests

Verification commands hang:

• Add timeout handling
• Check for interactive prompts
• Ensure commands are non-blocking
