repo-standards

repo-standards measures pull-request review size without executing repository code. Its repository rules are available for review but remain disabled until individually approved and explicitly activated by a consumer.

Where rules belong

• Exact tracked-tree facts—filenames, placement, topology, migrations, pull-request size, ownership, delivery/GitHub state, and repository-wide API/document sets—belong here.
• Source and configuration semantics for Python, TypeScript, SQL, Terraform/HCL, Markdown, YAML, JSON, and shell belong in sarj-ai/code-standards.
• If a path alone is sufficient to produce the finding, use Repo Standards. If source content is necessary, use Code Standards.

After a rule is approved, activate its stable ID in .repo-standards/repository.toml:

enabled_rules = ["repository/artifacts/bespoke-iac-verifiers"]

The locked Repo Standards release supplies the current reviewed implementation. Manifests never select historical rule versions; --enable-rule <rule-id>@<version> remains available only for legacy manifests and calibration runs.

Run it

Sarj repositories should use the single Code Standards setup path. It installs the canonical staged repository check, managed commit-message check, and authoritative pull-request history workflow without creating a second Python environment:

uvx --no-config --isolated --python 3.14 --from code-standards code-standards setup
code-standards doctor

The direct Repo Standards commands and hooks below remain available for standalone consumers and advanced debugging.

Use the current release without installing it:

uvx --from repo-standards repo-standards pull-request size . --base origin/main

For a persistent user installation:

uv tool install repo-standards
repo-standards pull-request size . --base origin/main

Upgrade with uv tool upgrade repo-standards. Automation should pin the package version or the GitHub Action's full commit SHA.

Pull-request commit policy

pull-request commits is strict by default and defaults to five non-merge pull-request commits. A pull request above that limit passes only when every commit subject begins with the complete, exact ASCII series (1/N) through (N/N) , unless a trusted transition exemption is verified. Indices must be unique, totals must match the actual commit count, and zero-padded or partial markers do not pass.

Authoritative GitHub CI must fetch complete history and pass the event payload as a file. Repo Standards reads the exact direct PR base/head objects, refs, and numeric repository identities; it never uses the synthetic merge commit in GITHUB_SHA. Exit status 1 means the history violates policy; 2 means required evidence was incomplete.

repo-standards pull-request commits . --github-event "$GITHUB_EVENT_PATH"

Local hooks use checked-in configuration and remain deliberately advisory because history may be shallow or stale and pre-commit runs before the pending commit exists. --quiet suppresses only a completed pass; findings and incomplete analysis remain visible. pre-push closes the normal one-commit feedback lag, while exact CI remains authoritative.

repo-standards pull-request commits . --advisory --quiet

When a series is not intentional, prefer one reviewable commit:

git rebase -i "$(git merge-base origin/dev HEAD)"

Configure local base discovery, commit-message enforcement, and narrowly scoped promotion/synchronization transitions in schema 6. Strict CI reads this TOML from the exact PR base commit, so a PR cannot raise its own limit or grant itself an exemption. Each transition also requires the exact destination, a same-repository PR, an immutable source-SHA branch suffix equal to the PR head, and proof that the head remains in the configured source ancestry. Protect automation branch namespaces so only the promotion app can create or update them.

schema_version = 6

[commit_message]
enforcement = "strict" # default in schema 6; use "observe" only for measured migrations

[pull_request.commit_history]
advisory_base_ref = "dev"
# maximum_commits = 5

[[pull_request.commit_history.transitions]]
id = "dev-preview"
source_ref = "dev"
base_ref = "preview"
head_prefix = "automation/promote-dev-"
# sha_prefix_length = 12

Repeat an explicit table for every trusted edge. Repo Standards rejects ambiguous prefixes, unsafe refs, duplicate IDs, and more than 64 transitions. Missing configuration keeps the strict five-commit default and grants no transition exemptions. Existing explicit evidence and JSON transition flags remain supported for non-GitHub providers and migration from 5.9.

Stacked PRs are evaluated against each PR's direct base, never the whole stack base. The composite Action reports merge_group as explicitly not applicable because a merge-queue commit aggregates already-evaluated PRs; keep the containing required workflow enabled for merge_group so GitHub still receives its required status. The explicit edited activity ensures retargeting always re-evaluates the new exact base.

Commit-message policy

Schema 6 enables Managed Conventional Header v1 by default. It checks only the first physical line; bodies, trailers, punctuation, prose, and language remain untouched. Valid headers use [(i/N) ][TICKET] type(scope)!: description, where the numbering and ticket prefixes and scope are optional. Types are the fixed Conventional Commits set: build, chore, ci, docs, feat, fix, perf, refactor, revert, style, and test.

The commit-msg hook safely repairs only unambiguous type casing and structural whitespace. It never guesses intent or rewrites prose. Semantic findings fail with a short actionable diagnostic, so a developer or coding agent can update the message and retry.

repo-standards commit-message .git/COMMIT_EDITMSG --fix-safe

Authoritative PR CI validates every direct base-to-head non-merge commit using the policy from the exact base object. A cryptographically attested promotion or synchronization transition bypasses inherited legacy messages; branch names, actors, bots, and forks never grant an exemption.

Pull-request commits Action and pre-commit hook

After a full-history checkout, use the dedicated Action inside an existing required job. Pin the release to its complete immutable commit SHA.

on:
  pull_request:
    types: [opened, synchronize, reopened, edited]
  merge_group:
    types: [checks_requested]

- uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7
  with:
    fetch-depth: 0
    persist-credentials: false
- uses: sarj-ai/repo-standards/pull-request-commits@FULL_RELEASE_COMMIT_SHA # v5.11.0

The published repo-standards-check hook validates the exact staged Git index at pre-commit. The repo-standards-pull-request-commits hook runs in advisory mode at pre-commit and pre-push. The repo-standards-commit-message hook runs at commit-msg, applies bounded safe normalization, and then enforces [(i/N) ][TICKET] type(scope)!: description. Real merge commits are accepted only when Git's MERGE_HEAD proves merge state. Temporary fixup!, squash!, and amend! messages are accepted locally so every Git autosquash mode remains usable, but exact PR CI rejects them if they remain in review history. Consumers that already lock Repo Standards may invoke the same commands from their existing hook manager to avoid a duplicate environment. All published Python hooks require Python 3.14.

GitHub Action

The Action measures size only. It enables no repository lint rules and needs no inputs on a pull_request event.

name: Pull-request size

on:
  pull_request:

permissions:
  contents: read

jobs:
  size:
    runs-on: ubuntu-latest
    timeout-minutes: 10
    steps:
      - uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7
        with:
          fetch-depth: 0
          persist-credentials: false
      - uses: sarj-ai/repo-standards@97b9aa444bc8e33bc8d217db75c9ca660a03d1eb # v5.16.0

The Action emits counted, excluded, and total line counts plus canonical JSON. Tests are recognized across Python, JavaScript/TypeScript, Go, JVM, Android, Xcode/Swift, .NET, Ruby, and Bats conventions. Mark generated or machine-owned artifacts in the trusted base revision:

path/to/generated/** pr-size-excluded

Thresholds, labels, comments, and approval requirements remain consumer policy. Use pull_request, never pull_request_target; this metric is not a security gate.

Safety model

• Repository contents come from one exact Git tree.
• Workflow YAML and API descriptions are parsed as inert data.
• Missing required evidence produces an inconclusive result rather than a false pass.
• Advisory commit-history analysis reports incomplete evidence without blocking local commits.
• The linter has no autofix or repository mutation mode.

Development

uv sync --locked
uv run pytest
uv run ruff check .
uv run basedpyright
uvx --no-config --isolated --python 3.14 \
  --from sarj-standards-bootstrap==2.0.3 \
  code-standards check --trust-repository-code

Build the same wheel and source distribution used by publishing:

uv build --no-sources

Releases are reconcilable. The protected workflow independently repairs a missing PyPI publication or GitHub Release from the same verified source revision.
