verification-before-completion
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
When & Why to Use This Skill
The 'Verification Before Completion' skill is a rigorous quality assurance framework designed to eliminate false success claims in software development. It enforces a 'gate function' that requires AI agents to provide fresh, empirical evidence—such as test logs, build exit codes, and linter outputs—before marking any task as complete, fixed, or ready for a Pull Request. By prioritizing evidence over assertions, it ensures high-reliability code delivery and maintains trust in automated workflows.
Use Cases
- Pre-PR Validation: Ensuring all unit tests and integration tests pass with zero failures before a developer or agent attempts to create a Pull Request.
- Regression Testing: Implementing a strict red-green-refactor cycle where a failure is first observed and then verified as resolved through repeated command execution.
- Build Integrity Checks: Verifying that complex builds (e.g., .NET/C# solutions) succeed with zero warnings and correct exit codes rather than relying on partial successes.
- Reliability Guardrails: Preventing the use of non-committal language like 'should work' or 'seems fixed' by mandating a 'run-and-read' protocol for every code change.
- Database Migration Safety: Confirming that EF Core or SQL migrations are valid by running them against both in-memory and integration environments before deployment.

Verification Before Completion
Overview
Claiming work is complete without verification is dishonesty, not efficiency.
Core principle: Evidence before claims, always.
Violating the letter of this rule is violating the spirit of this rule.
The Iron Law
NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
If you haven't run the verification command in this message, you cannot claim it passes.
The Gate Function
BEFORE claiming any status or expressing satisfaction:
1. IDENTIFY: What command proves this claim?
2. RUN: Execute the FULL command (fresh, complete)
3. READ: Full output, check exit code, count failures
4. VERIFY: Does output confirm the claim?
- If NO: State actual status with evidence
- If YES: State claim WITH evidence
5. ONLY THEN: Make the claim
Skip any step = lying, not verifying
Common Failures
| Claim | Requires | Not Sufficient |
|---|---|---|
| Tests pass | Test command output: 0 failures | Previous run, "should pass" |
| Linter clean | Linter output: 0 errors | Partial check, extrapolation |
| Build succeeds | Build command: exit 0 | Linter passing, logs look good |
| Bug fixed | Test original symptom: passes | Code changed, assumed fixed |
| Regression test works | Red-green cycle verified | Test passes once |
| Agent completed | VCS diff shows changes | Agent reports "success" |
| Requirements met | Line-by-line checklist | Tests passing |
C# .NET Specific (ECTSystem):
| Claim | Requires C# Verification | Not Sufficient |
|---|---|---|
| Build succeeds | dotnet build ElectronicCaseTracking.sln exit 0, 0 warnings |
Restore succeeded, IntelliSense green |
| Tests pass | dotnet test AF.ECT.Tests --no-build shows: X passed, 0 failed |
Individual test passed once |
| gRPC service works | Test includes RpcException with correct StatusCode | Code compiles, proto file exists |
| EF Core query works | InMemoryDatabase test passes + SQL Server test passes | Compiles, LINQ looks right |
| No warnings | dotnet build /p:TreatWarningsAsErrors=true succeeds |
CS warnings list is empty |
| Migration valid | dotnet ef migrations list + InMemoryDatabase test |
Migration file created |
Red Flags - STOP
- Using "should", "probably", "seems to"
- Expressing satisfaction before verification ("Great!", "Perfect!", "Done!", etc.)
- About to commit/push/PR without verification
- Trusting agent success reports
- Relying on partial verification
- Thinking "just this once"
- Tired and wanting work over
- ANY wording implying success without having run verification
Rationalization Prevention
| Excuse | Reality |
|---|---|
| "Should work now" | RUN the verification |
| "I'm confident" | Confidence ≠ evidence |
| "Just this once" | No exceptions |
| "Linter passed" | Linter ≠ compiler |
| "Agent said success" | Verify independently |
| "I'm tired" | Exhaustion ≠ excuse |
| "Partial check is enough" | Partial proves nothing |
| "Different words so rule doesn't apply" | Spirit over letter |
Key Patterns
Tests:
✅ [Run dotnet test] [See: X passed] "All tests pass"
$ dotnet test --no-build --logger "console;verbosity=minimal"
34 test(s) passed
❌ "Linter passed" (linter ≠ tests)
Regression tests (TDD Red-Green):
✅ Write test → Run (FAIL) → Fix code → Run (PASS) → Revert fix → Run (FAIL) → Restore → Run (PASS)
$ dotnet test AF.ECT.Tests --filter "MethodName" --no-build
FAIL: MethodName
[Fix code]
$ dotnet test AF.ECT.Tests --filter "MethodName" --no-build
1 passed
❌ "I've written a test" (without watching it fail then pass)
Build:
✅ [Run build] [See: exit 0] "Build passes"
$ dotnet build ElectronicCaseTracking.sln --no-restore
Building solution configuration 'Release|Any CPU'.
All projects are up to date for restoration.
All projects are up to date for generation.
All projects are up to date for compilation.
❌ "Restore passed" (restore ≠ build)
C# .NET Specific (ECTSystem):
gRPC service verification:
✅ Test written for both success AND exception paths
[Fact]
public async Task GetWorkflow_WithValidId_ReturnsWorkflow() { ... } ✓ PASS
[Fact]
public async Task GetWorkflow_WithNullId_ThrowsRpcException() { ... } ✓ PASS
❌ "Only tested success path" (missing exception test)
EF Core verification:
✅ Test uses InMemoryDatabase AND actual SQL Server connection tested
// Test with InMemory
var options = new DbContextOptionsBuilder<EctDbContext>()
.UseInMemoryDatabase("test")
.Options;
using var context = new EctDbContext(options);
// Verify query logic works
// Integration test with actual SQL Server connection
dotnet test AF.ECT.Tests/Integration --filter "GetWorkflow_Integration" --no-build
❌ "InMemory test passes" (without integration test)
Build warning verification:
✅ dotnet build ElectronicCaseTracking.sln /p:TreatWarningsAsErrors=true
Build succeeded. 0 errors, 0 warnings
❌ "Build succeeded" (with CS warnings present)
Why This Matters
From 24 failure memories:
- your human partner said "I don't believe you" - trust broken
- Undefined functions shipped - would crash
- Missing requirements shipped - incomplete features
- Time wasted on false completion → redirect → rework
- Violates: "Honesty is a core value. If you lie, you'll be replaced."
When To Apply
ALWAYS before:
- ANY variation of success/completion claims
- ANY expression of satisfaction
- ANY positive statement about work state
- Committing, PR creation, task completion
- Moving to next task
- Delegating to agents
Rule applies to:
- Exact phrases
- Paraphrases and synonyms
- Implications of success
- ANY communication suggesting completion/correctness
The Bottom Line
No shortcuts for verification.
Run the command. Read the output. THEN claim the result.
This is non-negotiable.
