Summary

  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.

Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.

AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview

This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.

Changes:

  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.
Reviewed changes
Copilot reviewed 2 out of 2 changed files in this pull request and generated 4 comments.
FileDescription
AGENTS.mdUpdates contributor documentation to reflect AI-driven backport decisions and the “always PR” policy.
.github/workflows/backport.ymlReworks triggers and logic to AI-decide backports on main pushes, support label override, and always open backport PRs with notifications.

Address PR review: randomized output delimiters and updated manual in…

…structions
- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.
@TooTallNate
Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.

Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.

Summary
  • Run on every push to main. AI analyzes each commit and decides whether to recommend a backport to stable, instead of relying on a manual backport-stable label being added to every PR. AI is given commit metadata, the full diff (capped at 200KB), and the associated PR's title/body when one exists.
  • Always open a PR — never push directly to stable. Even clean cherry-picks now go through a PR for human review. The PR title/body include AI's reasoning (or a note that conflicts were AI-resolved).
  • Label as override, not gate. The backport-stable label still works but now forces a backport regardless of the AI verdict (skips AI analysis entirely). Adding it before or after merge re-triggers the workflow via the existing pull_request_target: labeled event. This is the escape hatch when AI declines a backport you actually want.
  • No-backport notification. When AI decides against a backport, it leaves a comment on the source PR explaining its reasoning, with instructions for forcing a backport via the label.
  • Decision criteria (per Peter's Slack framing): recommend a backport for any commit that doesn't specifically build on main-only behavior — bug fixes, edge-case fixes, self-contained minor features, doc fixes, dependency bumps, infra/CI changes. Lean toward yes when in doubt; humans review the PR and can close it if not worth merging. Decline for changes building on main-only APIs, major breaking changes for the next major, changes confined to directories not maintained on stable (the docs/ app outside docs/content/, and skills/), and release plumbing.
  • Hardening. All actions/github-script interpolations of dynamic content (AI reasoning, etc.) moved to env: + process.env to prevent script injection.
Existing conflict-resolution behavior is unchanged: auto-resolve docs/ (non-content) / skills/ / pnpm-lock.yaml conflicts, then fall back to opencode for anything remaining.
AGENTS.md updated to describe the new behavior.
@TooTallNate
Restructure backport workflow with AI-driven decisions
31f71b0
Run the backport workflow on every push to main and have AI analyze each
commit to decide whether to recommend a backport to stable, instead of
relying on a manual backport-stable label. The action now always opens a
PR for human review and never pushes directly to stable. The
backport-stable label is preserved as a manual override that forces a
backport regardless of the AI verdict.

Pull request overview
This PR restructures the stable backport automation to run on every push to main, using AI to decide whether to open a backport PR, while keeping backport-stable as a manual override and ensuring backports never push directly to stable.
Changes:
  • Trigger backport workflow on push to main and use AI to decide “yes/no” backport per commit, with PR/commit context and a capped diff.
  • Always open a PR against stable (even for clean cherry-picks), and comment on the source PR when a backport is created or declined.
  • Update AGENTS.md to document the new AI-driven decision criteria, override behavior, and conflict-handling flow.

Address PR review: randomized output delimiters and updated manual in…
dbed18b
…structions
- Use uuidgen-based delimiters when writing multiline values (PR title,
body, AI reasoning) to $GITHUB_OUTPUT, so user-/model-controlled
content cannot collide with or inject into the heredoc terminator.
- Update the manual conflict-resolution instructions to push a backport
branch and open a PR against stable, matching the new "never push
directly to stable" policy.
- Document the head-commit-only behavior of the push trigger inline in
the workflow.
