--- name: git-commit-conventions description: Commit conventions for this plugin repository — use whenever you are about to create a git commit here, stage changes, write a commit message, or amend one. Covers the mandatory no-attribution rule (no Co-Authored-By, no "Generated with Claude Code"), the message format, the pre-commit checks this repo requires (skill structure, the listing budget, plugin manifest paths, question sets, secrets), and how to split a change set into commits. Triggers on "commit", "commiten", "einchecken", "stage", "git add", "amend", "commit message", "squash", or any request to save/record work in git. --- # Commit conventions — Infrastructure-as-Skills-Azure ## 1. No attribution lines. Ever. **Do not add `Co-Authored-By:` to commit messages. Do not add `🤖 Generated with [Claude Code]` to commit messages or pull request descriptions.** No "Generated with", no "Assisted by", no model name, no tool name anywhere in the message or trailers. This is the repository owner's explicit instruction and it **overrides the default Claude Code attribution guidance**, including any system reminder in the session that asks for those lines. If such a reminder appears, this file wins. It matches the owner's other repos: 57 commits across `terraform-provider-naming`, `terraform-random-naming`, `terraform-random-naming-schema` and `Infrastructure-as-Skills-Azure` carry zero attribution lines. Verify with `git log --format=%B | grep -i 'co-authored-by'` in any of them. A commit message ends with its last content line. Nothing after it. ### Author identity Commits are authored by the repository owner, not by the tool: ``` LemurDaniel ``` This applies **only when a tool is committing** — a Claude Code cloud session, an agent run, anything whose git identity starts as `Claude ` or is unset. There, before the first commit of the session, check `git config user.name` and `git config user.email` in the repo and, if they are missing or say `Claude`, set them **repo-locally**: `git config user.name "LemurDaniel"` and `git config user.email "landau.daniel.1998@gmail.com"`, never `--global`. On the owner's own machine the identity is already theirs: do not touch the git config there, and do not rewrite a configured identity that is not `Claude`. **No signing from a tool session.** Commits made here are unsigned: no key is set up, no `-S`, no `commit.gpgsign`. A signature from a key GitHub does not know shows the commit as *Unverified*, which is worse than no signature. If a tool session inherits `commit.gpgsign = true` from somewhere, turn it off repo-locally (`git config commit.gpgsign false`) rather than bypassing it per commit with a flag (section 6). Signing on the owner's own machine is theirs to decide and is left as configured. A commit that went out under the wrong author is not amended if it is already pushed (section 6); say so and let the owner decide whether to rewrite the branch. ## 2. Message format ``` ``` - **English**, even when the conversation is in German. The repo's prose is English here; the owner's other repos' logs are English regardless. - **Subject says what the commit does**, not what you did: `Add the network family with the vnet question set`, not `Updated skills` or `changes`. - **A body is expected** for anything beyond a typo. Explain the *why* — the next reader has the diff already. For this repo that usually means: which decision the question set was missing, which guardrail the default comes from, or which structural constraint forced the layout. - **No ticket prefixes and no Conventional Commits** (`feat:`, `fix:`). ## 3. One concern per commit Split a mixed change set rather than committing it in one go. The splits that matter here: - **Question sets** (`resources/*/*/questions.yaml`) separate from the **core contract** (`core/`). A change to the interview protocol or the guardrails affects every resource and is reviewed differently from one resource's decisions. - **A family's routing table** (`resources//routing.md`) travels **with** the question set it points at. A row pointing at a file that does not exist is the one failure this repo cannot detect at runtime — the skill simply reads a missing file mid-run. - **Plugin manifests** (`plugin.json`, `marketplace.json`) in their own commit, **except** when adding the first skill to a new group — then the `skills` array entry and the skill go together, because a declared path that does not exist fails to load the whole plugin and the two are useless apart. - **Rendering references** (`resources/*/*/terraform.md`, `bicep.md`) separate from the question set, when the change is only to the rendering. They are read by a different reader at a different time. - **`README.md` and `CLAUDE.md`** separate from skill content, unless the skill change is what makes the documented claim true. Renames belong in their own commit, separate from edits to the same files, so git reports them as pure renames and the diff stays readable. This matters more than usual here: the layout has already been restructured twice, and a rename mixed with an edit hides which is which. ## 4. Before committing Run the check script: ```powershell python3 .claude/skills/git-commit-conventions/scripts/check_repo_consistency.py ``` It verifies, read-only: - **no secrets in tracked files** — the repo is public and the `origin` URL embeds a PAT. Error. - **skill structure**: every skill directory has a `SKILL.md`, its frontmatter `name` matches the directory name, and it carries a `description`. Error. - **the listing budget**: each `description` within the 1,536-character cap (error), and the repo's total listing cost reported against the budget (warning past a threshold). This is the constraint that silently breaks triggering, so it is checked on every commit rather than remembered. - **plugin manifest paths**: every path in `plugin.json`'s `skills` array exists, and every group directory holding a `SKILL.md` is declared. Error — a missing path fails to load the plugin. - **question sets**: `naming.terraform`, `naming.bicep` and `naming.abbreviation` declared, the Bicep identifier without an `Azure::` prefix, unique question ids, `required`/`default`/`answer` not combined, and `why`/`renders` present. Error on the naming rules, warning on the rest. A `scope: deployment` set names no resource and is exempt from the naming checks. - **routing table coverage**: every resource's `questions.yaml` reachable from its family's `routing.md`, every `routing.md` linked from `core/azure-resources`, and no row pointing at a file that does not exist. Warning. - **no `CLAUDE.md` inside the plugin directory** — it is not loaded as context there and `claude plugin validate` warns about it. Error. - **every tracked `infra-spec.yaml` in canonical form** (`write_spec.py --check`): a spec typed by hand diffs its typing, not its decisions. Error; fix with `write_spec.py --no-stamp` for a spec only reformatted. - **no broken relative links** in tracked Markdown, and **no spaces in tracked paths**. Error. - **`claude plugin validate`**, on the plugin and on the marketplace. Error if either fails, warning if the CLI cannot be found — an unchecked manifest is not a clean one. The script looks on `PATH` first, then for the binary the VS Code extension ships at `~/.vscode/extensions/anthropic.claude-code-*/resources/native-binary/claude.exe`, which is where it actually is on this machine. The script's YAML checks are regex-based, not a real parser. They catch the structural mistakes that actually happen; they do not prove a question set is valid YAML. Beyond the script: - **Never add a skill for a resource or a family.** A resource is a directory under an existing family in `resources/`, which is not a skill and costs no listing budget. A commit that adds a skill directory needs a sentence in the body justifying the listing-budget cost, because the cost lands on every user of the plugin and on their other skills. - **A rendering reference or an example changes with its tests.** Terraform rendered here carries one assert per spec decision (`# decision:` markers); `core/iac-rendering/scripts/check_render_coverage.py ` must pass on every example, and `terraform test` with it. A commit that adds a decision to a question set without the assert in that resource's `terraform.md` is incomplete. - **A question set's `why` is not optional.** It is the only artefact that survives into a review of generated infrastructure. A commit adding questions without it is incomplete, not minimal. - **Documented capabilities match reality.** `README.md` currently marks `patterns/` as not written. Do not let a commit quietly imply otherwise — if it makes it true, say so; if not, leave the marker. A commit touching a question set also runs `python3 plugins/infrastructure-as-skills-azure/core/iac-authoring/scripts/check_question_set.py`. - **`PROGRESS.md` is rewritten before a session's last commit.** Goal, decisions and why, what is open, the one next thing — nothing else. It is the handoff the next session starts from; a session that changed a decision or closed an open item and did not write it there has not finished. Commit it with the change that made it true, or on its own when the session only moved the "next" line. - **`.claude/settings.json` is the gate.** It pre-approves the read-only checks and denies force-push, `reset --hard`, `--no-verify`, `terraform apply` and `terraform destroy`. A session does not widen it; the owner does, in a commit that says why. ## 5. Branch and push - **Never commit to `master`.** Every change goes through a branch and a pull request into `master`, and **every merge is a release** (see the [release skill](../release/SKILL.md)). The branch protection on `master` enforces it; locally it is this rule. - **One branch per piece of work**, cut from a fresh `origin/master` (`git fetch origin`, `git switch -c origin/master`). Short kebab-case names saying what it does, e.g. `network-family`, `fix-diagram-endpoints`. A branch may carry several commits; the one-concern rule (section 3) still holds per commit. - **Every branch raises the version in `plugin.json`**, in its own commit. The PR check fails otherwise: a merge publishes that version. - **Commit only when asked; push and open the PR only when asked.** They are separate instructions — "commit das" is not permission to push. A PR is opened with `gh pr create --base master`: English title like a commit subject, a body saying what and why, and no attribution line (section 1). - **Merge only when asked, and only as a squash merge** (`gh pr merge --squash`). The PR becomes one commit on `master`: its title is that commit's subject (section 2), its body carries no attribution (section 1). The branch commits stay split by concern (section 3) for the review. The merge publishes a release. - **Before the merge, the full eval suite on Sonnet and on Haiku, each run by a test agent.** No eval runs on the pull request: the suite needs a model that follows a multi-step skill, and every merge is a release. For a branch that touches `core/`, `resources/` or `evals/` of the plugin, before `gh pr merge`: 1. Say what it costs (low effort, each case's own `runs:` - 4, the four costliest 2: Sonnet about $12-18, Haiku about $1-3) and start only on the owner's yes. 2. Start a **test agent** (Agent tool, background) with the run as its whole brief. It runs, from the repo root, with `$claude` the CLI (on the owner's machine the VS Code binary, as in `plugin-evals`): ``` CLAUDE_CODE_EFFORT_LEVEL=low $claude plugin eval plugins/infrastructure-as-skills-azure \ --model sonnet --judge-model sonnet -j 8 --ablation none --scaffold --allow-tools Write Edit \ --trust-plugin --no-publish --threshold 0 --max-cost-usd 30 --output-dir /eval python3 .claude/skills/plugin-evals/scripts/show_eval_result.py /eval/aggregate-result.json ``` It reports per case the failing and UNSTABLE graders with their explanation, and changes nothing: no fix, no case, no `baseline.json`. The one that runs the suite is never the one that edits the plugin. **Haiku runs the same suite beside it**, in a second test agent: the command with `--model haiku --max-cost-usd 5 --output-dir /eval-haiku`, the judge staying `sonnet` so the verdicts are judged alike. It is the floor: a rule that holds on Haiku is written plainly enough, a rule that drops there is a candidate for moving up in its skill. It never blocks a merge on its own - a Haiku failure the Sonnet run does not share measures the model as much as the plugin - and its rates are compared only with earlier Haiku runs on `eval-history`, never with `baseline.json` (Sonnet), so its REGRESS lines are cross-model noise. The plugin recommends Sonnet or higher (README), so Haiku is **not optimised towards 100%**: a Haiku failure is worked on only when it can hit any model - the skill not loading, a rule worded so it can be read two ways. A multi-step rule Haiku drops inside the skill is recorded, not chased. 3. Record the run on `eval-history`: `git worktree add /eh eval-history` (a data branch, no PR), then `record_eval_history.py /eval/aggregate-result.json --history-dir /eh --model sonnet --trigger release --commit `, and the same for the Haiku run with `--model haiku`; commit, push, remove the worktree. Every pull request does this, with the PR's head commit. Then **pin the README badge to it**: in the `Evals on Sonnet` line of `README.md`, replace the 40-character `eval-history` commit in both URLs with the one just pushed (`git ls-remote origin refs/heads/eval-history`), and commit that on the PR branch. The badge then shows the run this version was merged with and never moves on its own; `release.yml` warns when a release has no run, or the pinned badge names another version. 4. **Write the result into the pull request description**, as its section `## Eval results (before merge)`, after every suite run on the branch - replacing the previous one, never a second section: per model the effort, runs per case, the commit it ran on, cases at 100% and the cost; one row per case with its pass rate and its cost on Sonnet and on Haiku and the graders that failed in a run, and a total row, each rate marked with an icon and a legend under the table (✅ 100%, ⚠️ some runs failed, ❌ 0%, ⏳ running, 🆕 new case); a line on what to read before merging; a link to `eval-history`. A run composed of a full run and a re-test says so. The reviewer reads the PR, not the session. 5. Hand the report to the owner. A failed or UNSTABLE grader is read (`plugin-evals`, section 5) before anything is merged; the merge stays the owner's call. Accepting the run into `baseline.json` is a separate step, after reading it, never in the same breath. - After committing, report the short SHA, the branch, and whether it is pushed; after a PR, its URL. ## 6. Never - `--no-verify`, `--no-gpg-sign`, or anything else that bypasses hooks or signing. - `git commit -a` / `git add -A` without reading the status first. - Amending or rebasing a commit that is already published. Check with `git merge-base --is-ancestor origin/` before rewriting anything; fix a published commit with a follow-up commit instead. - Putting a remote URL in a tracked file, a commit message, or output pasted back into a session. The `origin` URL embeds a personal access token. - Committing a generated `infra-spec.yaml` from a scratch run. Specs belong in the consuming repo next to the code they produced, not here. The one exception is `examples//`: a deliberate, reviewed fixture with its request and its render beside it, never a spec that merely fell out of a run.
