@7dgroup/dsh-skill-7d-git-commit

Author: 7DGroup

A DSH (DeepSeek Harness) bundle plugin that registers the 7d-git-commit skill on ctx.skills. Before generating any git commit message, the skill validates it against the 7DGroup commit convention and warns or guides the user to fix violations — a client-side guard that complements the server-side pre-receive hook on gitlab.

The bundled skill is a drop-in composition layer: install the bundle into a DSH profile and the skill becomes available in every session using that profile; remove the bundle to uninstall it cleanly.

Features

• Client-side commit validation before git commit is executed.
• 9 fixed Chinese type tags such as 【新增】, 【修复】, 【优化】, 【文档】, etc.
• Title length, punctuation, forbidden characters/phrases, and wording rules from the 7DGroup convention.
• Body formatting rules: numbered lists, max 70 chars per line.
• Exemptions for merge commits and emergency [skip-check] deployments.
• Bundled reference references/git-commit-message.md acts as the source of truth and is loaded on demand.
• Zero core changes — pure composition bundle.

Quick Start

Prerequisites: dsh CLI, Node ^22.19.0 || >=24.0.0, pnpm 10+.

Install via dsh CLI

dsh plugin --profile web add github:7dgroup-ai/dsh-skill-7d-git-commit

For the first git install, pnpm will refuse to run the build script until you add the exact package key to the profile's pnpm-workspace.yaml under allowBuilds. Then re-run the same command.

To avoid the build authorization, use a pre-built tarball or the published npm package:

dsh plugin --profile web add @7dgroup/dsh-skill-7d-git-commit

Install from within a dsh session (recommended)

The most direct way — just ask the agent in any dsh conversation, and it runs the install for you. Use the GitHub spec — the npm name @7dgroup/dsh-skill-7d-git-commit only works after the package is published:

安装插件 github:7dgroup-ai/dsh-skill-7d-git-commit

(Or in English: "Install the plugin github:7dgroup-ai/dsh-skill-7d-git-commit" — the agent executes the equivalent dsh plugin command through its session shell.)

For a git install the agent will hit the same pnpm allowBuilds gate and print the exact key to add to the profile's pnpm settings file (~/.dsh/profiles/<name>/pnpm-workspace.yaml); after you add it, ask the agent to retry and the skill is enabled.

Build and Test

pnpm install
pnpm build   # tsdown; also runs as `prepare` on git installs
pnpm test    # vitest

Usage

Once installed, mention any commit-related request in a dsh session:

Generate a commit message for the current changes.

You can also trigger the skill explicitly with the slash command:

/7d-git-commit

Example triggers:

• Generate a commit message for the current changes.
• Write a commit message for these changes.
• Check whether my commit message follows the 7DGroup convention.
• Fix the commit message so it passes the validation rules.

The skill will:

1. Analyze the changes.
2. Choose the best matching type tag from the 9 allowed categories.
3. Compose a subject line (【类型】动作 + 对象) ≤ 50 chars without trailing punctuation.
4. Add a numbered body for complex changes, each line ≤ 70 chars.
5. Run the validation checklist and reject or fix violations.

Commit Convention

See assets/7d-git-commit/references/git-commit-message.md for the full 7DGroup rules.

High-level requirements:

• Title format: 【类型】简短描述
• Title length: ≤ 50 characters after the tag
• No trailing 。, ，, ., ,
• Forbidden characters in title/body: @ # $ % ^ & * ~
• Forbidden phrases: temporary notes, TODO, FIXME, emotional language
• Body lines ≤ 70 chars, numbered list only

GitLab Integration

The plugin provides both a client-side DSH skill and a server-side GitLab hook. Use them together for "client pre-check + server enforcement".

Compatibility: The server-side integration is adapted for and verified on GitLab CE 19.2.0 (custom hooks + rule configuration).

• Client: assets/7d-git-commit/SKILL.md validates commit messages before git commit.
• Server: docs/gitlab-integration/pre-receive validates pushes before they reach GitLab.
• Rule source: assets/7d-git-commit/references/git-commit-message.md shared by both sides.

Integration overview

Why validate commit messages

The first thing you do when receiving a new code drop is read the git log. A messy log that does not tell you what each commit actually did makes reviews and maintenance painful. Well-formed commit messages (a changelog) help others review the code, produce Release Notes efficiently, and matter greatly for version management. That is why we use GitLab server-side hooks to validate the git change log and block non-conforming commits.

Design: enforce at the pre-receive stage

GitLab runs three server-side hooks after a push (the flow the server performs):

Hook	Stage	Role
pre-receive	before push is applied	runs as soon as the push reaches the GitLab server — the interception point
update	during push	commits the update into the GitLab repository
post-receive	after push	runs after the push succeeds — used for notifications

Flow:

flowchart LR
    A[user push] --> B{pre-receive<br>intercept before apply}
    B -- "non-zero" --> C[push rejected<br>non-conforming commit]
    B -- 0 --> D[update<br>apply to repository]
    D --> E[post-receive<br>notify]

Validating at the pre-receive stage: if a commit message does not conform, the hook exits with a non-zero code and the push never lands in the GitLab repository.

How it works

pre-receive reads the pushed refs from stdin as oldrev newrev refname (old commit id, new commit id, branch name), then uses git log to extract the author, date, and subject. A regex checks that the subject starts with an allowed prefix (the referenced article's example: fix|add|del|update|temp|test|revert|Merge); on mismatch it prints an error and exit 1 rejects the push.

Manual deployment (per the referenced article)

1. Locate the repository path: GitLab switched to hashed storage, so get the on-disk path via an admin account, e.g. /srv/gitlab/data/git-data/repositories/@hashed/78/5f/785f3ec7...git.
2. Create custom_hooks: inside the repository directory, create a custom_hooks folder with a pre-receive file (a shell script).
3. Make it executable: chmod +x pre-receive.
4. Verify with a local push: non-conforming commits fail to push; conforming ones go through.

The docs/gitlab-integration/ directory in this repo is the productionized version of that approach: it iterates over every ref on stdin (not just the first line), supports warn/reject modes, externalizes rules into commit-rules.conf, and adds audit logging plus DingTalk reports — deployable with install-hooks.sh as shown below.

Pitfalls

GitLab versions bundle different git versions, and the same command can produce different output across them. For example, git log --no-merges --date-order -1 output differs between git versions — do not rely on unverified command output in hooks.

Deploy server-side hooks

Copy docs/gitlab-integration/ to the GitLab server, then run:

# single-repo pilot
sudo bash install-hooks.sh --pilot devops/7dgroup

# after pilot passes
sudo bash install-hooks.sh --global

Rule synchronization

After updating docs/gitlab-integration/commit-rules.conf in this repo:

sudo bash scripts/sync-rules.sh --global --dry-run
sudo bash scripts/sync-rules.sh --global

Observation and reporting

# daily summary
sudo bash scripts/audit-report.sh --markdown

# send to DingTalk
export DINGTALK_WEBHOOK="https://oapi.dingtalk.com/robot/send?access_token=xxx"
sudo -E bash scripts/dingtalk-notify.sh

Switch to hard reject

1. Complete docs/gitlab-integration/switch-to-reject-checklist.md.
2. Change MODE="reject" in the deployed commit-rules.conf.
3. Take effect immediately on the next push.

For the full deployment SOP, see docs/gitlab-integration/deployment-guide.md.

Notes

1. The provider contributes a single fixed skill and offers no runtime customization.
2. prepare does not emit type declarations; the dsh loader only needs the runtime entry.
3. The build only transpiles; type errors are visible in your editor but not checked during build.
4. The docs/gitlab-integration/ files are not part of the DSH runtime bundle; copy them to the GitLab server on demand.
