Create manual test instructions
Resolve the input
- Ticket or requirements document (file or pasted text) — the only source: the checks follow it, and no code change is looked up.
- Code change — a branch, PR URL, commit range, pasted diff or patch file, or nothing (the
current branch). A commit range is diffed between its own ends. A branch or PR:
git fetchthe remotes, then diff from the merge base<base>with the target — a PR's base from its metadata, else the default branch of theupstreamremote when one exists, else oforigin, viagit ls-remote --symref <remote> HEAD; that failing, the sole existing candidate amongmain,master,develop/development, preferringupstream's remote-tracking ref, thenorigin's, then the local branch.git diff <base> <source>for a tip; a checked-out source is reviewed as its working tree:git diff <base>plus the untracked files (git ls-files --others --exclude-standard), read whole. Read the commit subjects and the PR title and description too. Then resolve the task's planning home — its<id>-<slug>/directory (no ticket → no id) or flat<id>-<slug>.*files in the project's planning directory, id and slug from the branch name or PR — and read the ticket and requirements there when present for the intent, the "before" and the edge cases; the checks still follow the code, a Reproduction part's steps aside (What to verify). No merge base →git fetch --unshallowand retry. Running forked, you can't ask mid-run: an ambiguous target, a failed fetch, still no merge base or an empty diff → write nothing and say in the final message what to pass on the next run; never guess a target.
Where needed for accurate navigation, also read the code the input cites and the design frames or screenshots it links when they are on disk.
Write the file
Next to an input ticket or requirements file, naming it by replacing .REQUIREMENTS or .TICKET
with .MANUAL-TEST (FOO.REQUIREMENTS.md → FOO.MANUAL-TEST.md); neither convention → append
.MANUAL-TEST before .md. A code change with a planning home → <id>-<slug>.MANUAL-TEST.md
beside the task's other artifacts. Otherwise (pasted text, a diff or patch file, a branch without
artifacts) follow the project's/user's convention for where plans live (default: .agents/plans/)
and write <id>-<slug>/<id>-<slug>.MANUAL-TEST.md there, id and slug from the branch name or PR,
else a kebab-case slug from the content. An existing manual-test file of that name is replaced;
the final message says so. Flag any guessed location or slug in the final message for the user to
verify.
The file must be followable by someone unfamiliar with the ticket — short but complete. Four parts:
- What changed — 1–2 sentences: the feature and the user-visible difference.
- How to get there — concrete navigation to the affected area (entry point, page/screen name, any prerequisite state).
- Before vs after — how the area behaved before, how it should behave now.
- What to verify — checklist of behaviors to confirm, including edge cases (empty values, multiple items, boundaries) where relevant. A requirements document's Reproduction part, in the input or read for a code change, gives the first check, a regression check: its steps, passed when the expected behaviour it records shows. A ticket's own reproduction field isn't that part. A behaviour resting on an Open question of the input goes under a closing Not settled yet line, never as a plain check: on a non-blocking question, with its tentative answer; on a blocking one, listed as undecided, naming who decides when the input names them, with no expected value — never invented. Each point where a code change differs from its ticket — built but never asked for, or asked for but not built — goes under a closing Differs from the ticket line, with nothing invented for the missing side.
A change with nothing a person can test by hand (a refactor, a dependency bump, a backend change with no visible effect) still gets the file: part 1 says why, the other parts stay empty.
Before writing, actually invoke explain-in-simple-language and follow it — reciting its rules from memory does not count. Not installed: plain words, one idea per sentence, and nothing named only by a stand-in the reader hasn't seen.
Do not modify any source files; the only file you write is the manual-test document.
When done, state the manual-test file's project-relative path and, for a branch or PR, the target and the source state (tip or working tree) you diffed.
