Procedure
Silent execution: The ONLY output is the commit message and the options question.
Do not print rules, steps, reasoning, thinking, or any commentary. Everything else
happens silently in your head.
1. Gather context
Before drafting you need two things: (a) what changed and (b) why it was needed.
Review the information already in your context from this session — what the user
has described, code you have written, and changes you have made. Do not run any
git commands to gather context. If both (a) and (b) are present, proceed directly
to drafting.
If either is missing, ask:
"What changed, and why was this change needed?"
Do not invent or assume details. Do not proceed until you have both.
2. Resolve author identity
git config user.name
git config user.email
Use the returned values in Signed-off-by:. If either is empty or the command
fails, ask the user for their name and email.
Never emit a placeholder like Your Name <your.email@example.com>.
3. Check atomicity
One logical change belongs in one commit — regardless of diff size. Renaming a
function across 50 files is still one logical change. A bug fix touching 3 lines
that also reformats whitespace is two changes.
If the changes span unrelated concerns (e.g., bug fix + refactor + dependency bump), say:
"These changes cover more than one concern. Which should this commit describe?"
Do not silently bundle unrelated changes.
4. Draft and self-validate
Draft following the format and rules below, then check every item before presenting:
Subject line follows type(scope): summary format
Type is one of: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert
Scope matches one of the scopes listed in .gitmessage at the repo root
Subject uses imperative mood, lowercase first letter, no period
Blank line between subject and body
Body explains why (motivation, contrast with previous behavior) — not just what
Body is prose — complete sentences in flowing paragraphs, no bullet points, no numbered lists, no sentence-per-line fragments
Lines wrap at 72 columns
Signed-off-by: present with real name and email, after the body
Fix any failure before presenting.
5. Present with options
Show the commit message in a code block. Then use ask_followup_question with:
Accept — always
Up to 3 alternatives — only if genuinely different (different emphasis, detail,
or angle); describe each in a short phrase from the actual content; omit if none
If the user types a request instead of clicking → apply it, return to Step 4, re-present.
HARD RULE: Do NOT run git commit or any git write command until the user
explicitly selects "Accept" (or equivalent confirmation) in Step 6. Presenting
the message is not permission to commit.
6. Execute commit (only after explicit user confirmation)
Once the user selects Accept:
Show the exact commands about to be run. Use multiple -m flags for the
multi-line format this repo requires:
git add <files>
git commit -m "feat(react): add specific feature" \
-m "Body explaining the motivation and what changed." \
-m "Signed-off-by: Name <email>"
Run the commands.
Show the resulting commit hash (output of git log -1 --oneline).
If the user selects an alternative or requests changes instead, return to Step 4.
Format
Use Conventional Commits: type(scope): summary — see .gitmessage at the repo
root for the full list of valid types and scopes.
feat(react): add graph search with prefix syntax
The usecase visualizer had no way to jump to a specific node without
scrolling through the whole graph. Larger diagrams made this painful
once node counts grew past a screen's worth.
This adds a search box that filters by label prefix and centers the
view on the first match.

Multi-line commit command (this repo requires a body — never use a single
-m flag alone):
git commit -m "feat(react): add graph search with prefix syntax" \
-m "Body text here." \
-m "Signed-off-by: Jane Developer <jane@example.com>"
