Summary

deploy.yml gets a first job, changed (ubuntu-latest, no checkout). On the daily scheduled run it ends the run in seconds when nothing the site is built from has moved:

  • this repository is at the commit the newest earlier run on master took (whatever its result, a cancelled run aside), or past it by the deploy job's deployed-sources.json commit alone;
  • agentos and agentos-extensions master are at the commits deployed-sources.json names;
  • the record is under 30 days old (at 30 the run builds, so the deploy job rewrites the record and the schedule is not disabled for 60 days without activity).

Only the build job gains needs: changed; deploy and rerun keep their conditions and skip with the build, so the publication contract's reading of their if: and concurrency groups is unchanged. A push, a pull request or a dispatch always builds; a re-run of a scheduled run (github.run_attempt above 1) always builds; a skip check that fails or gives no answer builds (!cancelled() && needs.changed.outputs.run != 'false'). The lookup reads the newest 100 runs.

Follow-up commit: 01d9a070. Master merged in at acd0b454.

Not merged on purpose: a push to master here builds and deploys the site to GitHub Pages and commits deployed-sources.json. It stays open for a deliberate merge.

How this was verified

CI only. This pull request's run on acd0b454: Skip an unchanged scheduled run passed (a pull request event, so it set run=true), build passed in 36 minutes, deploy and re-runs do not deploy skipped as they do on every pull request; links passed. scripts/publication-contract.test.mjs runs in build and evaluates deploy.if, rerun.if, the upload step's if: and the concurrency groups, none of which changed.

Migration notes

None

Checklist

  • Tests cover the changed behavior.
  • Docs are updated. (No docs page describes the schedule; the comment above the changed job does.)
  • The title follows Conventional Commits, with ! before the colon for a change that breaks users (feat!: or feat(api)!:).
  • No secrets or private data are included.
  • Every automated review thread is settled (how).
  • I have read this change and can explain every line.

The skip path itself (a scheduled event) has no test: it is decided by GitHub's schedule event and the runs API, which a pull request run cannot produce. The first scheduled run after the merge is the check.

Configuration

Add a scheduled-run check that skips builds when the deployed commit and source records are current, while failing open for other events, re-runs, or unsuccessful checks.

Walkthrough

The deployment workflow checks eligible scheduled runs against prior runs, source commits, and record age. It sets an output that controls whether the build job runs.

Changes: Scheduled deployment gating

Layer / File(s) Summary
Change check and build gate
.github/workflows/deploy.yml
The changed job checks only scheduled first attempts. It proceeds to build if lookups fail, sources moved, the record is at least 30 days old, or changes extend beyond deployed-sources.json. It skips the build only when the unchanged checks pass. The build job depends on this result and retains the cancellation condition.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Minimal · up to acd0b

Scheduled runs skip the build only when nothing it builds has moved and the deployment record is under 30 days old. All other cases build. The behavior matches the owner's stated policy and no merge-blocking risk remains. Adding tests for the new build gate would guard against future regressions.

ci(deploy): Skip unchanged scheduled builds

✨ Enhancement 🕐 20-40 Minutes

Grey Divider

AI Description

• Add a lightweight check to end daily runs when the site and its source repositories are unchanged.
• Build when inputs move, the deployment record reaches 30 days, or a lookup fails.
• Keep push, pull request, and manual builds, plus existing deployment conditions, unchanged.

High-Level Assessment

The API-only gate is appropriate: it avoids checkout and a costly build when a scheduled run has no new inputs, while defaulting to a build when it cannot establish that safely. Always building would retain the unnecessary daily cost.

Gate scheduled builds on source changes

• Adds a checkout-free job that compares the current run with an earlier workflow run, checks the recorded upstream commits, and enforces a 30-day record refresh. Only the build gains a dependency on its run decision; non-scheduled events and unsuccessful checks continue to build.

Action required

1. Failed builds leave site changes unpublished ✓ Resolved
Description
The last query accepts failed and in-progress runs as its baseline, and decide skips the
repository comparison when that run’s head_sha equals the scheduled run’s SHA. If a push
containing site changes fails before deployment while the recorded upstream sources remain current
and under 30 days old, the next scheduled run skips both build and deploy instead of publishing
those changes.

A re-run of a scheduled run now always runs its work, a skip check that fails or leaves no answer lets the work run, and the lookup reads the newest 100 runs instead of 20.

Add contract tests for the new build gate.

Assert build.needs and test build.if with run=false, run=true, a missing output after a failed check, and cancellation. Test scheduled reruns in the changed job, which sets the output used by the gate.

On the review of acd0b45:

  • Contract tests for the build gate (nitpick): not added. build.if and needs are evaluated by GitHub, not by code in this repository. The cases the nitpick names are covered by the expression and the check's defaults: run=false skips, run=true and an empty output both build (!= 'false'), and a cancelled run stops (!cancelled()). The publication contract test already pins deploy.if, rerun.if and the concurrency groups, and none of them changed. The skip path needs a schedule event, which a pull request run cannot produce. No failing input was given, so this one stays as it is.
  • Description check: the body now follows .github/pull_request_template.md.

This pull request stays open on purpose. A push to master deploys the site to GitHub Pages, so it waits for a deliberate merge.
