Agent skill
test-evidence-review
Quality review of test files and manual evidence documents. Goes beyond existence checks — evaluates assertion coverage, edge case handling, naming conventions, and evidence completeness. Produces ADEQUATE/INCOMPLETE/MISSING verdict per story. Run before QA sign-off or on demand.

Test Evidence Review
/smoke-check verifies that test files exist and pass. This skill
goes further — it reviews the quality of those tests and evidence documents.
A test file that exists and passes may still leave critical behaviour uncovered.
A manual evidence doc that exists may lack the sign-offs required for closure.
Output: Summary report (in conversation) + optional production/qa/evidence-review-[date].md
When to run:
- Before QA hand-off sign-off (
/team-qaPhase 5) - On any story where test quality is in question
- As part of milestone review for Logic and Integration story quality audit
1. Parse Arguments
Modes:
/test-evidence-review [story-path]— review a single story's evidence/test-evidence-review sprint— review all stories in the current sprint/test-evidence-review [system-name]— review all stories in an epic/system- No argument — ask which scope: "Single story", "Current sprint", "A system"
2. Load Stories in Scope
Based on the argument:
Single story: Read the story file directly. Extract: Story Type, Test Evidence section, story slug, system name.
Sprint: Read the most recently modified file in production/sprints/.
Extract the list of story file paths from the sprint plan. Read each story file.
System: Glob production/epics/[system-name]/story-*.md. Read each.
For each story, collect:
Type:field (Logic / Integration / Visual/Feel / UI / Config/Data)## Test Evidencesection — the stated expected test file path or evidence doc- Story slug (from file name)
- System name (from directory path)
- Acceptance Criteria list (all checkbox items)
3. Locate Evidence Files
For each story, find the evidence:
Logic stories: Glob tests/unit/[system]/[story-slug]_test.*
- If not found, also try: Grep in
tests/unit/[system]/for files containing the story slug
Integration stories: Glob tests/integration/[system]/[story-slug]_test.*
- Also check
production/session-logs/for playtest records mentioning the story
Visual/Feel and UI stories: Glob production/qa/evidence/[story-slug]-evidence.*
Config/Data stories: Glob production/qa/smoke-*.md (any smoke check report)
Note what was found (path) or not found (gap) for each story.
4. Review Automated Test Quality (Logic / Integration)
For each test file found, read it and evaluate:
Assertion coverage
Count the number of distinct assertions (lines containing assert, expect, check, verify, or engine-specific assertion patterns). Low assertion count is a quality signal — a test that makes only 1 assertion per test function may not cover the range of expected behaviour.
Thresholds:
- 3+ assertions per test function → normal
- 1-2 assertions per test function → note as potentially thin
- 0 assertions (test exists but no asserts) → flag as BLOCKING — the test passes vacuously and proves nothing
Edge case coverage
For each acceptance criterion in the story that contains a number, threshold, or "when X happens" conditional: check whether a test function name or test body references that specific case.
Heuristics:
- Grep test file for "zero", "max", "null", "empty", "min", "invalid", "boundary", "edge" — presence of any is a positive signal
- If the story has a Formulas section with specific bounds: check whether tests exercise at minimum/maximum values
Naming quality
Test function names should describe: the scenario + the expected result.
Pattern: test_[scenario]_[expected_outcome]
Flag functions named generically (test_1, test_run, testBasic) as
naming issues — they make failures harder to diagnose.
Formula traceability
For Logic stories where the GDD has a Formulas section: check that the test file contains at least one test whose name or comment references the formula name or a formula value. A test that exercises a formula without mentioning it by name is harder to maintain when the formula changes.
5. Review Manual Evidence Quality (Visual/Feel / UI)
For each evidence document found, read it and evaluate:
Criterion linkage
The evidence doc should reference each acceptance criterion from the story. Check: does the evidence doc contain each criterion (or a clear rephrasing)? Missing criteria mean a criterion was never verified.
Sign-off completeness
Check for three sign-off lines (or equivalent fields):
- Developer sign-off
- Designer / art-lead sign-off (for Visual/Feel)
- QA lead sign-off
If any are missing or blank: flag as INCOMPLETE — the story cannot be fully closed without all required sign-offs.
Screenshot / artefact completeness
For Visual/Feel stories: check whether screenshot file paths are referenced in the evidence doc. If referenced, Glob for them to confirm they exist.
For UI stories: check whether a walkthrough sequence (step-by-step interaction log) is present.
Date coverage
Evidence doc should have a date. If the date is earlier than the story's last major change (heuristic: compare against sprint start date from the sprint plan), flag as POTENTIALLY STALE — the evidence may not cover the final implementation.
6. Build the Review Report
For each story, assign a verdict:
| Verdict | Meaning |
|---|---|
| ADEQUATE | Test/evidence exists, passes quality checks, all criteria covered |
| INCOMPLETE | Test/evidence exists but has quality gaps (thin assertions, missing sign-offs) |
| MISSING | No test or evidence found for a story type that requires it |
The overall sprint/system verdict is the worst story verdict present.
## Test Evidence Review
> **Date**: [date]
> **Scope**: [single story path | Sprint [N] | [system name]]
> **Stories reviewed**: [N]
> **Overall verdict**: ADEQUATE / INCOMPLETE / MISSING

### Story-by-Story Results
#### [Story Title] — [Type] — [ADEQUATE/INCOMPLETE/MISSING]
**Test/evidence path**: `[path]` (found) / (not found)
**Automated test quality** *(Logic/Integration only)*:
- Assertion coverage: [N per function on average] — [adequate / thin / none]
- Edge cases: [covered / partial / not found]
- Naming: [consistent / [N] generic names flagged]
- Formula traceability: [yes / no — formula names not referenced in tests]
**Manual evidence quality** *(Visual/Feel/UI only)*:
- Criterion linkage: [N/M criteria referenced]
- Sign-offs: [Developer ✓ | Designer ✗ | QA Lead ✗]
- Artefacts: [screenshots present / missing / N/A]
- Freshness: [dated [date] — current / potentially stale]
**Issues**:
- BLOCKING: [description] *(prevents story-done)*
- ADVISORY: [description] *(should fix before release)*
---
### Summary
| Story | Type | Verdict | Issues |
|-------|------|---------|--------|
| [title] | Logic | ADEQUATE | None |
| [title] | Integration | INCOMPLETE | Thin assertions (avg 1.2/function) |
| [title] | Visual/Feel | INCOMPLETE | QA lead sign-off missing |
| [title] | Logic | MISSING | No test file found |
**BLOCKING items** (must resolve before story can be closed): [N]
**ADVISORY items** (should address before release): [N]
7. Write Output (Optional)
Present the report in conversation.
Ask: "May I write this test evidence review to
production/qa/evidence-review-[date].md?"
This is optional — the report is useful standalone. Write only if the user wants a persistent record.
After the report:
- For BLOCKING items: "These must be resolved before
/story-donecan mark the story Complete. Would you like to address any of them now?" - For thin assertions: "Consider running
/test-helpers [system]to see scaffolded assertion patterns for common cases." - For missing sign-offs: "Manual sign-off is required from [role]. Share
[evidence-path]with them to complete sign-off."
Verdict: COMPLETE — evidence review finished. Use CONCERNS if BLOCKING items were found.
Collaborative Protocol
- Report quality issues, do not fix them — this skill reads and evaluates; it does not modify test files or evidence documents
- ADEQUATE means adequate for shipping, not perfect — avoid nitpicking tests that are functioning and comprehensive enough to give confidence
- BLOCKING vs. ADVISORY distinction is important — only flag BLOCKING when the gap leaves a story criterion genuinely unverified
- Ask before writing — the report file is optional; always confirm before writing
