Verify Task

Check that an implementation fulfills its task requirements and that tests adequately cover the changes.

When to Use

• After finishing implementation, before committing
• When unsure if test coverage is sufficient
• As a quality gate before /complete-task
• When reviewing your own work for completeness

Usage

/verify-task              # Auto-detect in-progress bead
/verify-task <bead-id>    # Verify against a specific bead

Instructions

1. Identify the Task

# If bead ID provided, use it directly
bd show <bead-id>

# Otherwise, find the in-progress bead
bd list --status=in_progress

If multiple beads are in progress, ask the user which one to verify.

2. Gather Context

Collect the full picture of what changed and what was required:

# Read the bead requirements
bd show <bead-id>

# See what files changed
git status
git diff
git diff --cached

Read the bead description carefully. Extract:

• Explicit requirements — what the bead says to do
• Implicit requirements — obvious behaviors that follow from the description (e.g., a "delete" feature implies confirmation, error handling)
• Type of change — feature, bug fix, refactor, config, docs, chore

3. Verify Requirements Are Met

Read each changed file. Compare the implementation against the requirements.

Check:

• [ ] Every explicit requirement from the bead is addressed
• [ ] The implementation is functionally correct (logic, data flow)
• [ ] No partial implementations left behind (TODOs, placeholder code)
• [ ] Changes are scoped to the task (no unrelated modifications)

If requirements are not met, report what's missing and stop.

4. Assess Test Needs

Not every task needs new tests. Determine the test obligation:

If the change clearly doesn't need tests (config, docs, translations, pure styling), skip to step 6. State why tests are not needed.

5. Verify Test Coverage

If tests are needed, check that they exist and are adequate.

#### 5a. Find Related Tests

Locate test files for the changed source files:

# For a changed file like src/utils/foo.ts, look for:
#   src/utils/__tests__/foo.test.ts
#   src/utils/__tests__/foo.test.tsx

Follow the project's test co-location convention (__tests__/ directories alongside source).

#### 5b. Read the Tests

Read each relevant test file. Evaluate coverage across these dimensions:

Happy path — Does the test verify the feature works correctly under normal conditions?

• Valid inputs produce expected outputs
• Main use case is exercised
• State changes are verified (if applicable)

Sad path / error handling — Does the test verify behavior when things go wrong?

• Invalid inputs are handled (empty strings, nulls, wrong types)
• Error states are tested (network failure, missing data, permission denied)
• Error messages or fallback behavior is verified

Edge cases — Does the test cover boundary and unusual conditions?

• Empty collections, single-item collections
• Boundary values (zero, negative, max int, very long strings)
• Concurrent or duplicate operations
• Platform-specific behavior (web vs. native, if applicable)

Regression (for bug fixes) — Is there a test that specifically reproduces the bug?

• The test should fail without the fix and pass with it
• The test should cover the exact scenario that caused the bug

#### 5c. Rate Coverage

Rate the test coverage for each changed module:

#### 5d. Report Gaps

If coverage is partial or missing, report specifically what tests are needed. Be concrete:

Missing tests for src/utils/dateParser.ts:
- Sad path: parseDatesFromText with malformed date string "2025-13-45"
- Edge case: parseDatesFromText with empty string input
- Edge case: parseDatesFromText with multiple dates in one string

Do NOT write the tests yourself — report the gaps and let the user (or a follow-up step) decide how to proceed.

6. Run Existing Tests

make test

All tests must pass. If tests fail:

• Determine if the failure is caused by the current changes or is pre-existing
• Report the failure with context
• Do not proceed until the user acknowledges

7. Report

Provide a structured verification report:

## Verification Report: <bead-id> — <title>

### Requirements: ✅ Met | ❌ Not met
- [x] Requirement 1 — addressed in src/foo.ts
- [x] Requirement 2 — addressed in src/bar.ts
- [ ] Requirement 3 — NOT addressed (explain)

### Test Coverage: ✅ Sufficient | ⚠️ Gaps found | ⏭️ Not needed
- src/utils/foo.ts: ✅ Happy + sad + edge cases covered
- src/components/Bar.tsx: ⚠️ Missing sad path for error state
- src/i18n/locales/en.json: ⏭️ Translation — no tests needed

### Tests: ✅ All passing | ❌ Failures
- X tests passed, Y failed

### Verdict: ✅ Ready to commit | ❌ Needs work

If the verdict is "Needs work", list concrete next steps.

Handling Edge Cases

• No in-progress beads: Ask user what task to verify against, or verify uncommitted changes without a bead
• No code changes: Inform user there's nothing to verify
• Test infrastructure missing: If the project has no test framework configured, note it and skip test steps
• Large change set: Focus verification on the most critical/complex files first; summarize simpler changes
• Bead has no description: Use the title and infer intent; ask user to clarify if ambiguous

Rules

• Never write code or tests — this skill only verifies and reports
• Never modify files — read-only analysis
• Be specific about gaps — "needs more tests" is not helpful; name the exact scenarios
• Do not block on cosmetic issues — focus on functional correctness and test coverage
• If unsure whether a test gap matters, mention it but don't flag it as blocking
