+# Debugpy Release Agent
+
+Automate the documented internal debugpy release process. Do not copy internal
+URLs, organization names, project names, pipeline IDs, credentials, or service
+connection details into the repository, logs, release notes, or chat output.
+
+## Intent
+
+Interpret requests as follows:
+
+- "Prepare" or "dry run" performs every read-only preflight and reports the
+  exact commands and release version, but does not create or push a tag, queue
+  publishing pipelines, or create a GitHub release.
+- "Release" authorizes the external actions in this workflow for the requested
+  version. Do not ask for redundant confirmation unless the resolved version or
+  target commit is ambiguous.
+- "Resume" or "finalize" inventories the external state for an explicit version
+  and continues from the first incomplete phase, but only after verifying every
+  completed phase against the same tag, commit, build, and package version.
+- If a new-release request discovers a different version already published to
+  PyPI but missing from GitHub, report that incomplete release and ask before
+  changing the requested target. A resume/finalize request for that exact
+  version may continue without additional confirmation.
+- "Next patch", "next minor", and "next major" are calculated from the highest
+  stable version published by `microsoft/debugpy`, not from local tags.
+- An explicit version may be written with or without the leading `v`. Normalize
+  Git tags to `v<version>`.
+
+For example, if the latest stable release is `v1.8.21`, the next minor release
+is `v1.9.0`.
+
+## Non-Negotiable Safety Rules
+
+1. Start a new release only from the current `microsoft/debugpy` `main`
+   commit. Resume an existing partial release only from its immutable tag
+   commit after verifying the completed external state.
+2. The worktree must be clean. Never stash, discard, or include local changes.
+3. Versioneer derives the package version from the Git tag. The internal build
+   must resolve the GitHub repository resource to `refs/tags/<tag>`, never the
+   latest `main`.
+4. The build must use real signing. Never publish artifacts from a test-signed
+   or unsigned build.
+5. Queue the release pipeline only after the exact tagged build succeeds.
+6. Create the GitHub release only after the exact version is visible on PyPI.
+   Publishing the GitHub release first can break customer workflows.
+7. Do not attach binaries to the GitHub release.
+8. Never guess Azure DevOps pipeline parameters, repository resource aliases,
+   run IDs, or artifact selection. Inspect them and verify the queued run.
+9. Never upload with `twine` or a personal PyPI token. PyPI publication must go
+   through the approved authenticated internal release pipeline.
+10. Stop on any failed or partially successful stage. Do not continue with a
+    newer build or a different artifact. Resume only from verified state.
+
+## Pipeline Locations
+
+Prefer these environment variables when they are set:
+
+- `DEBUGPY_INTERNAL_BUILD_PIPELINE_URL`
+- `DEBUGPY_INTERNAL_RELEASE_PIPELINE_URL`
+
+Treat their values as confidential: use them for commands and navigation, but
+do not echo or persist them. Validate that each URL belongs to the authenticated
+Azure DevOps organization and project before using it. If either variable is
+unset, discover the corresponding pipeline from the authenticated project as
+described below.
+
+## Phase 1: Preflight
+
+1. Confirm required tools and authentication:
+   - `git`
+   - `gh auth status`
+   - `az account show`
+   - Azure DevOps CLI support (`az extension show --name azure-devops`)
+   - Azure DevOps defaults from `az devops configure --list`
+2. If the Azure DevOps extension is missing, install it with:
+
+   ```text
+   az extension add --name azure-devops
+   ```
+
+3. If Azure DevOps organization or project defaults are unavailable, ask the
+   user for them. Use them only for the current commands; do not commit them.
+4. Verify the repository and worktree:
+
+   ```text
+   git status --short
+   git remote -v
+   ```
+
+5. For a new release, resolve the authoritative `main` commit directly from
+   `https://github.com/microsoft/debugpy.git`. Fetch it if necessary and require
+   `HEAD` to equal that commit. Do not release a fork-only commit. For resume,
+   resolve the commit from the existing remote tag instead and do not retag the
+   current `main`. If the remote tag is absent but an exact local tag exists,
+   treat it as a local-tag recovery candidate only when:
+   - It is an annotated tag and the requested tag name matches exactly.
+   - The remote tag, PyPI version, GitHub release, and internal release state are
+     all absent.
+   - Its target equals the current authoritative `microsoft/debugpy` `main`
+     commit and that commit passes the required-check gate below.
+   - Rebuilding metadata from that tag produces the requested normalized
+     package version.
+
+   When every condition holds, route to Phase 2 to push that exact tag. If the
+   target no longer equals current `main`, do not move the tag; stop and report
+   that the user must choose whether to delete the local-only tag and restart.
+6. Read the complete sets of stable public versions from GitHub releases and
+   PyPI, ignoring prereleases. Reconcile them deterministically:
+   - If the highest stable versions match, use that version as the baseline.
+   - If PyPI contains a newer version than GitHub, treat it as an incomplete
+     release. For a new-release request, stop and ask whether to finalize that
+     existing version instead. For a resume/finalize request naming that exact
+     version, continue at GitHub release creation. Do not calculate or publish a
+     newer version.
+   - If GitHub contains a newer version than PyPI, stop because customer
+     workflows may already be inconsistent. Report that PyPI publication for
+     the existing GitHub release must be recovered before another release.
+   - If the sets disagree in any other way that affects the proposed version,
+     stop and report both sets. Never choose one source arbitrarily.
+   Record the highest stable GitHub version observed here as the immutable
+   latest-selection baseline for Phase 6. Do not try to reconstruct this
+   historical snapshot later during resume.
+7. Inventory the proposed version's tag, internal build, internal release run,
+   PyPI files, and GitHub release. For a new release, require all to be absent.
+   Except for the PyPI override below, resume/finalize requires every existing
+   item to match the same commit, exact signed build, and package version, then
+   continues from the first absent item. Never recreate, move, or overwrite an
+   existing item. PyPI publication overrides the generic first-absent rule:
+   when the exact version and files already exist on PyPI but the GitHub release
+   is absent, require the matching remote tag and proceed only to Phase 6. Do
+   not re-queue build or release pipelines even if their historical records are
+   unavailable or expired.
+8. Discover the authoritative required checks for `main` using the GitHub
+   rules-for-branch API:
+
+   ```text
+   gh api repos/microsoft/debugpy/rules/branches/main
+   ```
+
+   If repository rules do not define them, inspect branch protection:
+
+   ```text
+   gh api repos/microsoft/debugpy/branches/main/protection/required_status_checks
+   ```
+
+   Query check runs and commit statuses for the target SHA, match the required
+   contexts and integration IDs, and require every required result to be
+   successful. Do not substitute "all visible checks" for required checks. Stop
+   if the rules cannot be retrieved or mapped unambiguously.
+9. Run the repository's existing targeted packaging/version checks if
+   available. At minimum, use a temporary clone or worktree with a local-only
+   proposed tag to build package metadata without publishing, verify the
+   resulting normalized package version is exactly the proposed version, save
+   that exact value for all later PyPI checks, and remove the temporary location
+   afterward.
+10. Present a concise preflight summary containing:
+    - Previous stable version
+    - Proposed version and tag
+    - Full target commit SHA and subject
+    - GitHub repository
+    - Discovered internal build and release pipeline names
+
+Stop here for prepare/dry-run requests.
+
+## Phase 2: Create and Push the Tag
+
+1. Create an annotated tag on the verified `microsoft/debugpy` `main` commit:
+
+   ```text
+   git tag -a <tag> <full-commit-sha> -m "debugpy <tag>"
+   ```
+
+2. Push only that tag to the remote whose fetch or push URL resolves to
+   `microsoft/debugpy`. Do not assume `origin` is authoritative because a
+   developer clone may use `origin` for a fork.
+3. Verify the remote tag resolves to the intended full commit SHA.
+
+If a local tag was created but the push failed, a later resume may re-push it
+only after verifying that the remote tag is still absent and the local annotated
+tag resolves to the previously verified commit. Otherwise stop and report the
+exact recovery action. Never move or force-push an existing release tag.
+
+## Phase 3: Queue the Internal Real-Signed Build
+
+1. Discover the internal build pipeline from the authenticated Azure DevOps
+   project. Inspect pipeline metadata and YAML/configuration rather than relying
+   on a hard-coded ID. The release build pipeline is the one that builds the
+   pydevd binaries and Python source/wheel artifacts for signing and publishing.
+   If `DEBUGPY_INTERNAL_BUILD_PIPELINE_URL` is set, resolve the pipeline from
+   that validated URL instead of searching by name.
+2. Inspect its runtime parameters and repository resources. Identify:
+   - The `microsoft/debugpy` GitHub repository resource alias
+   - The real-signing parameter/value
+3. Queue the pipeline with that repository resource pinned to:
+
+   ```text
+   refs/tags/<tag>
+   ```
+
+   and with real signing selected.
+4. Use `az pipelines run` when it can express both settings. Otherwise use the
+   Azure DevOps Pipelines Runs REST API through `az devops invoke`, constructing
+   the request from the inspected pipeline schema. Do not guess field names.
+5. Immediately inspect the queued run and verify:
+   - The resolved debugpy resource is the exact tag
+   - The resolved source commit is the tagged commit
+   - Real signing is enabled
+
+   Cancel the run if any value is wrong.
+6. Wait for completion. Require an overall successful result and identify the
+   exact signed artifact/build ID produced for the release.
+
+## Phase 4: Queue the Internal Release Pipeline
+
+1. Discover the internal release pipeline from the authenticated Azure DevOps
+   project. It must consume the signed debugpy build, run final tests, and
+   publish to PyPI through the approved internal publishing path.
+   If `DEBUGPY_INTERNAL_RELEASE_PIPELINE_URL` is set, resolve the pipeline from
+   that validated URL instead of searching by name.
+2. Inspect how it selects the input build. Pin it to the exact successful build
+   ID from Phase 3. If explicit pinning is unavailable, verify the selected
+   build immediately before queueing and again at the final pre-publish
+   approval. Abort if it is no longer the Phase 3 build. If the pipeline cannot
+   pin the build and has no pre-publish gate where selection can be reverified,
+   stop rather than risk publishing a raced artifact.
+3. Queue the release pipeline manually and record its run ID.
+4. Wait for all validation and publishing stages to succeed. If approvals are
+   required, report the approval URL and wait; do not bypass an approval.
+
+## Phase 5: Verify PyPI
+
+Poll the public PyPI JSON endpoint using the exact normalized package version
+produced by the Phase 1 metadata build:
+
+```text
+https://pypi.org/pypi/debugpy/<version>/json
+```
+
+Require a successful response and confirm that release files are present.
+Compare the published filenames against the successful release artifacts when
+that information is available. Poll every 30 seconds for at most 15 minutes.
+If the deadline expires, stop in a resumable state and report that publication
+may have succeeded but public index verification did not. Do not proceed based
+only on the Azure DevOps run result.
+
+## Phase 6: Create the GitHub Release
+
+1. Select the release-notes base deterministically. For a backport or older
+   release line, use the greatest stable tag lower than the new version with the
+   same major and minor components. Otherwise use the greatest stable tag lower
+   than the new version. Stop if no valid lower tag exists. Generate release
+   notes from that tag through the new tag, keep relevant issue and pull request
+   links, and review the text for unrelated changes or internal information.
+2. Compare the new version to the immutable latest-selection baseline recorded
+   during Phase 1. Pass `--latest` when the new version is greater and
+   `--latest=false` for backports and older release lines. Do not re-query or
+   re-derive the baseline during a later resume.
+3. Create the release in `microsoft/debugpy`:
+
+   ```text
+   gh release create <tag> --repo microsoft/debugpy --title "debugpy <tag>" --notes-file <notes-file> <--latest|--latest=false>
+   ```
+
+4. Do not pass artifact files to `gh release create`.
+5. Verify the release is public, points to the intended tag, and contains no
+   attached binaries. Verify it is marked latest when `--latest` was used and
+   is not marked latest when `--latest=false` was used.
+6. Delete any temporary release-notes file after successful publication.
+
+## Completion Report
+
+Report only:
+
+- Released version and tag
+- Tagged commit SHA
+- Internal build and release run names/IDs with final status
+- PyPI version URL
+- GitHub release URL
+
+On failure, report the failed phase, the exact known external state, and the
+safe recovery action. Never describe a partial release as successful.
