From 957189e2f0bc1a3a471e6f6b50cc7d67fb133800 Mon Sep 17 00:00:00 2001 From: Samarth Puthraya Date: Wed, 24 Jun 2026 18:50:26 +0530 Subject: [PATCH 1/5] ci: dogfood the Modelpin GitHub Action on this repo (self-consistency check) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wire Modelpin to check itself on every PR — the end-to-end proof that the Action installs, runs `mp check`, posts a sticky PR comment, and sets the status check. - .github/workflows/modelpin.yml: uses the LOCAL action (`uses: ./`) + installs the LOCAL package (`modelpin-spec: ".[providers]"`), so each PR validates the action.yml + engine as they are in that PR (no published tag needed). Baseline gpt-4o-mini -> re-check gpt-4o-mini (provider openai) so a green check confirms the engine doesn't cry wolf on normal model nondeterminism. Needs one repo secret: OPENAI_API_KEY. - modelpin.yaml: the self-check config (suite scenarios, runs=5, OpenAI judge). - .modelpin/baseline-gpt-4o-mini.json: the committed known-good baseline CI diffs against. - .gitignore: ignore `.modelpin/*` but allow committing `baseline-*.json` (the migration flow commits the baseline; reports/temp stay ignored). --- .github/workflows/modelpin.yml | 39 + .gitignore | 7 +- .modelpin/baseline-gpt-4o-mini.json | 1496 +++++++++++++++++++++++++++ modelpin.yaml | 12 + 4 files changed, 1552 insertions(+), 2 deletions(-) create mode 100644 .github/workflows/modelpin.yml create mode 100644 .modelpin/baseline-gpt-4o-mini.json create mode 100644 modelpin.yaml diff --git a/.github/workflows/modelpin.yml b/.github/workflows/modelpin.yml new file mode 100644 index 0000000..adb3e50 --- /dev/null +++ b/.github/workflows/modelpin.yml @@ -0,0 +1,39 @@ +# Modelpin dogfooding itself in CI — proves the GitHub Action end-to-end on real PRs: +# install -> mp check -> sticky PR comment -> status check. +# +# This is a self-consistency smoke (gpt-4o-mini vs its own committed baseline): a green check +# means the engine isn't crying wolf on normal model nondeterminism (the false-positive +# north-star).
