What does the PR do?

Aligns this repository with the org-wide setup consolidated in triton-inference-server/.github:

  • .pre-commit-config.yaml: shared baseline hooks, conventional-commit message validation (commit-msg stage), and the centralized add-license hook from the org .github repository (rev: v1.4.3 — excludes .github/ templates, never rewrites LICENSE files).
  • Pre-commit CI runs only on files modified by the PR.
  • Caller stub for the org-wide reusable conventional-pr workflow (@v1.4.3): validates the PR title against Conventional Commits (hard gate — it becomes the squash-merge commit), derives one human-readable label per distinct type found in the title and all conforming commit subjects (e.g. ci:CI/CD, feat:feature, fix:fix), enforces org-wide label colors/descriptions, detects cherry-picks, and fails if no type is derivable and no type label is assigned.
  • No per-repo templates: PR templates and issue routing are inherited from the org-wide defaults in triton-inference-server/.github (issues route to the server repository).

Repo-specific: local issue templates are removed — issues route to the server repository via the org-wide default.

Depends on triton-inference-server/.github#5 (pinned tags current: v1.4.3 — already exist, CI is green).

Pros / Cons

Pros

  • Single home (org .github repo) for hooks, templates, issue routing, and the PR-title workflow — one change propagates everywhere.
  • Repos carry only a config file and two small workflow stubs; no template copies to drift.
  • Commit/PR title format enforced both locally (commit-msg hook) and in CI (reusable workflow), with automatic type labels.
  • License hooks never modify LICENSE files.

Cons / risks

  • Version-pinned dependency on the org .github repository (tags are write-once; changes ship as a new tag + rev bump).
  • Template inheritance requires the org .github repository to remain public.

Related PRs:

Test plan

  • pre-commit validate-config passes; pre-commit run --files <PR diff> passes locally with the centralized hooks pinned to the .github branch SHA.
  • After .github#5 merges and v1.4.3 exists: the conventional-pr check validates this PR's own title and applies the ci label.
  • No LICENSE file content is changed by this PR.

Caveats

  • None beyond the merge-order note above.

Checklist

  • PR title follows <commit_type>: <Title> (conventional commit)
  • I ran pre-commit locally on all files changed by this PR and it passes
  • Copyright header is correct on all changed files
  • External contributors: I have read the Contribution guidelines and signed the Contributor License Agreement

Adopt the shared pre-commit baseline: two-line SPDX header, conventional
commit message validation (commit-msg stage), and the centralized
add-license / add-spdx-license hooks from developer_tools v0.2.0.
Run pre-commit CI only on files modified by the PR, and roll out the
standard issue templates and the simplified single PR template.

Greptile Summary

This PR aligns the repository with the org-wide CI/CD baseline consolidated in triton-inference-server/.github: it removes local issue templates (routing to the server repo), adds a thin conventional-pr caller workflow, and rewrites the pre-commit workflow to use null-delimited xargs with --diff-filter=d for robustness. The .pre-commit-config.yaml gains a commit-msg stage, fixes the broken --extend-ignore flake8 argument (extraneous space), and migrates the add-license hook from developer_tools to the org .github repo at v1.4.3.

  • conventional-pr.yml: uses a mutex if condition to route same-repo PRs through the safer pull_request event and fork PRs through pull_request_target, keeping permissions narrow (pull-requests: write, issues: write, contents: read).
  • pre-commit.yml: replaces pre-commit/action@v3.0.1 with an explicit pip install + run pipeline; adds a pre-commit environment cache keyed on the config file hash, and filters deleted files before passing paths to pre-commit run.
  • Issue templates deleted: bug_report.md and feature_request.md are removed in favour of org-wide defaults.

Confidence Score: 5/5

Safe to merge — changes are confined to CI configuration and issue templates with no production code touched.

All changes are CI/tooling configuration. The pull_request_target pattern is implemented correctly with a mutex if condition and minimal permissions. The flake8 arg fix and hook migration are straightforward. The only nit is the unpinned pre-commit binary version on cache misses, which does not affect correctness today.

.github/workflows/pre-commit.yml — the pre-commit binary version is not pinned; consider pinning to avoid unexpected breakage on cache misses.

Important Files Changed

Filename Overview
.github/workflows/conventional-pr.yml New thin-caller workflow delegating to org-wide reusable conventional-pr@v1.4.3; correctly gates same-repo PRs on pull_request and fork PRs on pull_request_target with a mutex if condition; permissions are minimal and include the previously missing contents: read.
.github/workflows/pre-commit.yml Replaces pre-commit/action with a manual pip-install-and-run approach; adds pre-commit cache, null-delimited xargs for path safety, and --diff-filter=d to skip deleted files. The pre-commit binary version is not pinned, which may cause reproducibility issues on cache misses.
.pre-commit-config.yaml Adds commit-msg hook stage (conventional-pre-commit v4.4.0), fixes flake8 --extend-ignore arg (removes erroneous space), and migrates add-license hook from developer_tools@v0.1.0 to .github@v1.4.3.
.github/ISSUE_TEMPLATE/bug_report.md Deleted — issue routing is delegated to org-wide defaults in triton-inference-server/.github; no logic change.
.github/ISSUE_TEMPLATE/feature_request.md Deleted alongside bug_report.md — same rationale, issues will route to the server repository via the org-wide template.

P2 Version tag contradicts PR description

The workflow pins the reusable caller to @v1.4.2, but the PR description consistently references v1.4.1 (e.g. "pinned tags current: v1.4.1 — already exist, CI is green"). The same mismatch appears in .pre-commit-config.yaml at the add-license hook (rev: v1.4.2). If v1.4.2 is the intended final tag, the description should be updated; if v1.4.1 was intended, both files were bumped unintentionally.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Fixed - documentation drift: the descriptions have been refreshed to the current pinned tag v1.4.3 (they lagged behind the tag revisions; the tag exists and CI is green fleet-wide).

Comment thread .github/workflows/conventional-pr.yml
- conventional-pr stub: dual pull_request/pull_request_target triggers
  so fork PRs from external contributors get labeled too (the reusable
  workflow never checks out PR code); explicit contents:read; pinned
  v1.4.3.
- pre-commit workflow: robust modified-files runner (null-delimited
  paths, deletion-only PRs handled, deleted paths filtered, no
  undocumented -r flag, cache keyed on config hash).
- flake8 args quoted correctly (the flow-scalar form split at commas
  and silently reduced the select list).
- hooks pinned to .github v1.4.3.

Closing: the team is moving away from centralized org-level configuration in favor of per-repository self-contained setups (see triton-inference-server/server#8897 for the first decentralized implementation). Branch retained for reference. TRI-1100
