PR Test Plan

Generate a manual test plan for the changes in the current branch. The plan should focus on what a developer/reviewer needs to manually verify — real user flows, integration behavior, and observable outcomes. Leave input validation, error branches, and edge cases to unit tests.

Determine Scope

Default (no scope specified): diff the current branch against the repo's base branch.

Detect the base branch in order — stop at the first success:

1. gh repo view --json defaultBranchRef -q '.defaultBranchRef.name' 2>/dev/null
2. git remote show origin 2>/dev/null | grep "HEAD branch" | cut -d: -f2 | xargs
3. git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@'

Do not assume main or master. If all methods fail, ask the user.

Once resolved, run:

git diff <base>...HEAD -- ":(exclude)*.lock" ":(exclude)package-lock.json" ":(exclude)pnpm-lock.yaml" ":(exclude)package.json"

If the user specifies a scope, use the corresponding command instead:

Scope	Command	What it covers
unstaged	git diff HEAD -- <excludes>	All uncommitted changes (staged + unstaged)
last commit / last 1 commit	git diff HEAD~1...HEAD -- <excludes>	Changes in the most recent commit
last N commits	git diff HEAD~N...HEAD -- <excludes>	Changes in the last N commits
entire repo	git ls-files | grep -vE "\.(lock|snap)$|package-lock\.json|pnpm-lock\.yaml"	All tracked source files; no diff — generate a full application test plan covering all major flows and integration points

For all diff commands, apply: -- ":(exclude)*.lock" ":(exclude)package-lock.json" ":(exclude)pnpm-lock.yaml" ":(exclude)package.json"

Instructions

Step 1: Determine scope

Use Determine Scope above to resolve the scope and get the diff (or file list for entire repo).

Step 2: Gather change context

Run all of these and capture the results:

git diff $BASE_BRANCH...HEAD --name-only
git diff $BASE_BRANCH...HEAD --stat
git log $BASE_BRANCH..HEAD --oneline

For non-branch scopes (unstaged, last N commits), adapt the commands accordingly — replace $BASE_BRANCH...HEAD with the scoped range (e.g. HEAD~N...HEAD), and replace git log with git log HEAD~N..HEAD --oneline.

Step 3: Detect project tooling

Check what's available in the project so you can reference real commands (not generic guesses):

• Makefile targets: make help 2>/dev/null || grep -E '^[a-z_-]+:.*##' Makefile makefiles/*.mk 2>/dev/null
• Package manager: Look for pyproject.toml (uv/pip), package.json (npm/pnpm), Cargo.toml (cargo), go.mod (go)
• Test runners: Look for pytest.ini, pyproject.toml [tool.pytest], jest.config.*, .mocharc.*
• Project docs: Read AGENTS.md, CLAUDE.md, CONTRIBUTING.md, or README.md for project-specific test/build instructions
• CI config: Check .github/workflows/, Makefile, or Taskfile.yml for existing test commands

Prefer project Makefile targets and documented commands over raw tool invocations. If the project has make test_unit, use that instead of uv run pytest tests/unit/.

Step 4: Categorize changes and confirm with user

Group changed files into categories. Common categories (adapt based on actual changes):

• Feature code -- new commands, API routes, services, UI components
• Configuration / docs -- config files, markdown, schemas, manifests
• Tests -- new or modified test files
• Build / deploy -- Makefiles, CI, Dockerfiles, scripts
• Deletions -- removed files or deprecated code

Present the detected categories to the user with a summary of what changed in each. Ask them to confirm or adjust before generating the full plan.

Example confirmation format:

I found 3 change areas in this branch:

1. CLI agent mode -- new --agent flag on setup command (cli/commands/setup.py, cli/cli.py)
2. Skills restructuring -- SKILL.md rewrite, new reference docs, deleted shell scripts
3. Test fixes -- E2E test stability improvements (4 test files)

Should I generate the test plan for all 3, or would you like to adjust?

Step 5: Generate the test plan

For each confirmed category, generate a test section following these rules:

Severity & importance markers

Tag every test step with one of these emojis in the step title:

Emoji	Meaning	When to use
🔴	Critical	Core functionality — if this fails, the feature is broken
🟢	Expected	Standard behavior that should work — moderate confidence but worth verifying
🔵	Nice-to-have	Polish, UX, non-blocking — skip if short on time

Example: 1a. 🔴 **Pre-register a profile end-to-end**

Formatting rules

• Numbered sections with separator lines (---) between them
• Numbered sub-steps within each section (1a, 1b, 1c...)
• Each sub-step has an emoji tag + bold title describing what to test
• Each sub-step has a copy-paste command in a fenced code block (or manual UI steps if applicable)
• Each sub-step has a "Verify:" line stating what success looks like
• One command per code block -- never stack multiple commands in one block with comments between them
• Use Makefile targets when available instead of raw tool commands
• For commands requiring env vars, put them inline: GROVE_API_URL=http://localhost:8000 make test_e2e_suite

What to focus on (and what to skip)

DO include — things you must verify manually:

• Happy-path user flows end-to-end (the main thing the feature does)
• Integration points — does component A actually talk to component B correctly?
• State transitions — does data persist, propagate, and display correctly across the system?
• Resumption / retry behavior — if a multi-step process fails midway, does retry work?
• UI rendering — does the new section/field/page show up and look right?
• API response shape — do new fields appear in real responses?
• Existing behavior preserved — does the change break anything that was already working?

DO NOT include — leave these for unit tests:

• Invalid input validation (wrong types, missing fields, malformed data)
• Boundary values and off-by-one checks
• Error message wording verification
• Permission/auth edge cases (401/403 responses)
• Schema validation failures

Failure-path test column

For any changed file that has multi-phase logic (e.g., validate → external I/O → DB write), add a "Failure-path" column to the test coverage table:

| File Changed           | Unit | Integration | E2E | Failure-path |
|------------------------|------|-------------|-----|--------------|
| routes/account.py      | ❌   | ❌          | ✅  | ❌           |
| db/display_names.py    | ✅   | ❌          | ❌  | ⏭️           |

The "Failure-path" column asks: does at least one test inject a failure into a non-first phase of multi-phase work?

• For a route that does verify token → DB read → external API call → DB write, a failure-path test mocks the external API to raise and asserts the route logs context and returns a typed error (not a silent 500).
• Mark ⏭️ only for files with no exception-bearing branches (pure utilities, type definitions).
• For route handlers and DB helpers with multi-step logic, ❌ is the default until a test exists.

Quick smoke test section

Always end with a "Quick Smoke Test" section -- the 2-3 commands a reviewer would run if they only have 60 seconds. Tag each with the appropriate emoji.

Step 6: Write output

1. Write the plan to TEST_PLAN.md in the repo root
2. Print a summary to the terminal showing the section count and a one-liner per section

Terminal summary format:

Wrote TEST_PLAN.md with 4 sections:

  1. CLI Agent Mode -- 4 test steps (🔴×2, 🟢×1, 🔵×1)
  2. Skills Restructuring -- 3 test steps (🔴×1, 🟢×2)
  3. Automated Tests -- 2 test steps (🟢×2)
  4. Quick Smoke Test -- 3 commands

Run `cat TEST_PLAN.md` to view the full plan.

Style Reference

Follow the same style used in cmd-pr-description:

• Bold the what, plain text the how
• No fluff -- every step must verify something real that a human needs to see
• Copy-paste ready -- a reviewer should never need to edit a command
• Separate code blocks -- one command per block, bold header above it
