Mathieu Benoit 55a093a86d [ADD] convention : ce qu'un sujet de commit doit dire
Le manuel encadrait le corps en détail — pourquoi, dix lignes par langue, ce
qu'on ne répète pas du diff — et ne disait du sujet que « courte, à
l'impératif ». Le sujet est pourtant lu cent fois pour une fois que le corps
l'est : git log --oneline, un blame, un bisect, une note de version.

Faute de règle, les sujets dérivent vers le symptôme et la métaphore, qui se
lisent bien sans nommer la partie du système en jeu. La règle ajoute une
épreuve, pas un gabarit : lire le sujet seul, sans diff ni corps, et savoir
ce qui change et où. Les trois exemples avant/après viennent de l'historique
du dépôt, un exemple inventé ne convainquant personne.

--- EN ---

The manual framed the body in detail — why, ten lines per language, what not
to repeat from the diff — and said of the subject only that it be short and
imperative. Yet the subject is read a hundred times for every reading of the
body: git log --oneline, a blame, a bisect, a release note.

With no rule, subjects drift towards the symptom and the metaphor, which read
well without naming the part of the system at stake. The rule adds a test,
not a template: read the subject alone, with no diff and no body, and be able
to say what changes and where. The three before/after pairs come from the
repository's own history, an invented example convincing nobody.

Context

  • Git status: !git status
  • Full diff: !git diff HEAD
  • Current branch: !git branch --show-current
  • Last 5 commits (for style reference): !git log --oneline -5

Task

Write a commit that satisfies AI_POLICY.md — the OCA generative AI policy ERPLibre adopts — and the conventions below.

Resolve the model — {MODEL}

Run this first. It reads the model from the CURRENT session transcript, which is the only source that stays right when the model is switched mid-session with /model or a CLI flag:

python3 -c "
import glob, json, os, sys
sid = os.environ.get('CLAUDE_CODE_SESSION_ID', '')
hits = glob.glob(os.path.expanduser('~/.claude/projects/*/%s.jsonl' % sid)) if sid else []
mid = ''
for path in hits[:1]:
    with open(path) as fh:
        for line in fh:
            try:
                m = json.loads(line).get('message', {}).get('model', '')
            except Exception:
                continue
            if m and not m.startswith('<'):
                mid = m
if not mid:
    sys.exit('UNKNOWN')
mid = mid.removeprefix('claude-')
parts = [p for p in mid.split('-') if not (len(p) == 8 and p.isdigit())]
print('Claude %s %s' % (parts[0].capitalize(), '.'.join(parts[1:])))
"

It prints the trailer value: Claude Opus 5, Claude Sonnet 4.6, Claude Haiku 4.5. There is deliberately no fallback name — on UNKNOWN, use the model you know you are running as, and never a value read from a settings file: ~/.claude/settings.json usually has no model key at all, so it would quietly declare the default instead of the truth.

Tags

Tag Usage
[UPD] Update existing code, data or configuration
[FIX] Bug fix
[ADD] New module, file or capability
[IMP] Improvement to something that already works
[REF] Refactoring, no observable behaviour change
[REM] Remove code or module
[MOV] Move or rename
[I18N] Translations

The first five cover every one of the last 400 commits. Reach for [REM], [MOV] or [I18N] only when one of them genuinely fits better.

[TAG] scope: short description in imperative mood

Explain WHY the change was made — the diff already shows what. Name the
symptom that led to it, and what was measured rather than assumed.
Wrap at 80 characters.

The subject line

The subject is read a hundred times for every time the body is read: in git log --oneline, in a blame, in a release note, in a bisect. It has one job — say what the code is about.

The test. Read the subject alone, with no diff and no body. Can you say which part of the system it concerns, and what is now different about it? If not, it is not finished.

Name the thing, then what changed about it. The symptom, the quoted error and the metaphor are EVIDENCE, and evidence belongs in the body. A subject built on them reads well and tells the next reader nothing:

Instead of Write
[FIX] nettoyage : les enfants s'en vont avec leur rebond [FIX] nettoyage : les entrées ssh qui rebondissent par une VM effacée
[FIX] proxmox : « il manque le stockage » était le symptôme, pas la cause [FIX] proxmox : signaler pmxcfs à terre, et non « aucun stockage »
[FIX] migration: un module fautif n'emporte plus tout le lot [FIX] migration: isoler l'échec d'un module dans la désinstallation

The scope is not the subject. proxmox says WHERE; the words after the colon must say WHAT. A subject that works with its scope removed is usually the right one.

Summarise the whole commit, not its largest piece. When the work has two faces — a guard moved and the check that proves it, a screen and the service under it — the subject covers both or the commit should have been two. If the only honest subject needs an and joining two unrelated things, split it.

It must be complete in 72 characters. A subject cut mid-phrase by --oneline has failed at the one place it is read most. Write it to fit rather than trimming it afterwards: drop the adjectives, keep the nouns.

Keep it short

The body answers one question: why was this necessary. Stop once it is answered — the reader owes you nothing beyond that.

Ten lines per language. Fifteen is already long. Past that, the reasoning belongs in a document or a code comment, and the commit points at it. The budget is per language: bilingual doubles everything, so it buys terseness, it does not excuse length.

Cut, in this order:

  • Anything the diff already says. adds function X is visible; X because the DHCP lease can be stale is not.
  • Headings and bullet lists. If the change really needs sections, it needs several commits.
  • Every clause that would not change what a reader does: no this commit, no I decided to, no summary of the summary, no restating the subject.

Keep, always: the symptom that led to the change, the figure you measured rather than assumed, and one line naming what you verified and how. A single Checked: 4 jobs, 1.63 s at parallelism 1 vs 0.58 s at 4 is worth three paragraphs of prose.

Bilingual body

Every AI-assisted commit carries its body twice. Write it first in whichever language you were thinking in, then the marker, then the translation.

The marker names the language of what FOLLOWS it: --- FR --- after an English body, --- EN --- after a French one. One marker per commit, never both.

Translate, do not re-summarise: a reader of either language must get the same reasoning, the same measured figures and the same caveats.

The Assisted-by trailer

AI_POLICY.md makes this binary — there was AI involvement or there was not, with no threshold to judge. Anything from a single suggestion to fully autonomous coding means the trailer, and it says nothing about the quality of the work.

  • One Assisted-by: line per model. A session that switched models declares each of them, one line each.
  • NEVER name an AI in Co-authored-by:: authorship of a work by a machine is legally undefined. That field is for other HUMANS who worked on the change. You are already the author, so never co-author yourself.
  • No blank line between trailers.

Rules

  • Subject: imperative mood, 72 characters maximum, aim for 50.
  • scope is the Odoo technical module (sale_order, account, stock) or the area of the repository (script todo, qemu ssh, migration).
  • The commit stands on its own: state what was verified, and how. If a claim was not checked, say so rather than implying it was.
  • If you cannot explain and defend every line, do not commit it.

Size and pace

A patch under 30 lines in a single file is the reference point. Past ~500 lines the policy asks for prior agreement with a maintainer — say so instead of committing quietly. When several unrelated modules are touched, propose splitting into separate commits before writing anything.

Execute

The timezone comes from the system, as it should: nothing is forced here, so each contributor's commits carry their own zone. If yours land at +0000, the machine itself is on UTC — common on a server or a VM — and the fix belongs there, sudo timedatectl set-timezone <Area/City>, because it affects every commit and not just this one.

The identity is passed explicitly with -c, which sets the author AND the committer. --author alone sets only the author, and a checkout with no configured user.email then fails on the committer.

Use a heredoc rather than -m: a body with quotes, backticks or accented characters survives it unharmed.

git add -A
git -c user.name="Your Name" -c user.email="your@email.com" commit -F - <<'MSG'
