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).

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 org-wide CI standards by adding a thin conventional-pr workflow caller, updating the pre-commit CI to use caching and robust deleted-file filtering, and migrating the add-license hook from developer_tools to the centralized .github repository at v1.4.3.

  • conventional-pr.yml: New workflow stub delegating to the org-wide reusable workflow; correctly routes same-repo PRs through the safe pull_request event and fork PRs through pull_request_target (write token required for labeling, with a well-guarded condition that prevents the job from running on the wrong event type).
  • pre-commit.yml: Replaces the pre-commit/action composite action with a direct pip install + cache approach; adds --diff-filter=d to skip deleted files and null-delimiter handling for paths with spaces.
  • .pre-commit-config.yaml: Adds default_install_hook_types for commit-msg stage, a conventional-pre-commit hook, fixes flake8 arg quoting, and migrates the add-license hook to the .github repo at v1.4.3.

Confidence Score: 5/5

CI-only change with no application logic; the pull_request_target guard condition is correctly implemented and well-documented.

All three files contain only CI/configuration changes. The pull_request_target routing logic in conventional-pr.yml is correct — the mutual-exclusion condition prevents duplicate runs and avoids exposing a write token to fork PR code. No application code is touched.

No files require special attention beyond verifying that v1.4.3 of triton-inference-server/.github exists and is green before merging.

Important Files Changed

Filename Overview
.github/workflows/conventional-pr.yml New workflow stub calling the org-wide reusable conventional-pr workflow at v1.4.3; uses pull_request_target with a correct guard condition to enable labeling on fork PRs without exposing write token to PR code.
.github/workflows/pre-commit.yml Replaces pre-commit/action with a direct pip install and cache step; adds null-delimited deleted-file filtering and --diff-filter=d; actions/cache is pinned only to a major version (v4) while other actions use exact versions.
.pre-commit-config.yaml Adds default_install_hook_types for commit-msg stage, conventional-pre-commit hook, fixes flake8 arg quoting, and migrates add-license hook from developer_tools to .github at v1.4.3.

P1 Version tag mismatch with PR description

The PR description states the pinned tag is v1.4.1 in every relevant place ("pinned tags current: v1.4.1 — already exist, CI is green", "rev: v1.4.1", "@v1.4.1"), but both this file and .pre-commit-config.yaml reference v1.4.2. If v1.4.2 does not yet exist on triton-inference-server/.github, this workflow call will fail at runtime. If it does exist, the PR description is stale and the dependency note ("Depends on … tags current: v1.4.1") is misleading for reviewers trying to verify the merge-order prerequisite.

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).

- 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
