Prepare Providers Documentation (AI-driven)

This skill replaces the manual commit-by-commit classification step that the release manager normally performs when running breeze release-management prepare-provider-documentation. Instead of asking the release manager to type d/b/f/x/m/s/v for each commit, the skill drives the classification itself — inspecting every PR (with extra care for potentially breaking changes), scoping multi-provider PRs to the slice that touched the current provider, and asking the release manager only when genuinely uncertain.

The skill keeps the existing breeze tooling as the source of truth for template generation. Claude only owns the classification + version bump + changelog entries; everything else (__init__.py, README.rst, pyproject.toml, conf.py, get_provider_info.py, index.rst) is still regenerated by breeze release-management prepare-provider-documentation --reapply-templates-only.

[!IMPORTANT] This is a release-manager workflow. It mutates provider.yaml and changelog.rst for many providers in one pass. Always run on a clean working tree (or in a dedicated branch) and let the release manager review the diff before committing.

When to Use This Skill

Use during the regular provider release cycle, in place of either of:

breeze release-management prepare-provider-documentation
breeze release-management prepare-provider-documentation --incremental-update

…when the release manager wants Claude to classify the changes instead of doing it by hand. The skill covers the same scope: classifying changes, bumping versions, generating changelog sections, reapplying templates, and folding new commits into an already-prepared release PR (incremental update).

Two entry points:

Initial run — classify everything from scratch for a new release. Follow Phases 1–5 below.
Incremental update — extend an existing release PR with commits that landed on main since the changelog was first generated (typical when rebasing a release PR before merging). Skip ahead to the Incremental Update section after Phase 5.

Do not use this skill for:

--only-min-version-update runs (these don't need classification — just run breeze directly).
Releasing from a non-main base branch unless you also pass the right --base-branch to the breeze invocations described below.
Removing providers (state changes belong in a separate PR).

Inputs You Need Before Starting

Ask the release manager (and confirm by reading the answers back) for:

RELEASE_DATE in YYYY-MM-DD (or YYYY-MM-DD_NN) format, e.g. 2026-04-26. This is what breeze stamps into providers/.last_release_date.txt.
Base branch — defaults to main. Only override when releasing from a provider-specific branch (e.g. provider-cncf-kubernetes/v4-4).
Subset of providers, if any. By default, classify every provider that has pending changes since its last release tag. If the release manager wants a subset (or has set DISTRIBUTIONS_LIST), use that list.
Include flags: whether to include --include-not-ready-providers and/or --include-removed-providers.

Set the environment for the session:

export RELEASE_DATE=<date>
# Optional, scopes everything to a subset
export DISTRIBUTIONS_LIST="<provider1> <provider2> ..."

Make sure the apache-https-for-providers git remote exists and is up to date — running breeze the first time below will recreate and fetch it.

Workflow

The skill runs in five phases. Mark tasks with TaskCreate for each phase and tick them off as you go — the release manager wants to see progress.

Phase 1 — Discover and pre-classify pending changes (deterministic)

The source of truth for "what changed since last release" is the same git query breeze uses internally: commits between the latest release tag for that provider (providers-<id>/<version>) and apache-https-for-providers/<base-branch>, restricted to the provider's own folders.

Run the deterministic classifier — it discovers every provider with pending changes and pre-classifies each commit with hard-coded, high-confidence rules, flagging only the genuinely ambiguous ones as needs_llm. No random answers, nothing to discard:

breeze release-management classify-provider-changes \
    --base-branch main \
    --output-file /tmp/provider-changes.json
# scope to a subset by appending provider ids, e.g. ... amazon cncf.kubernetes

The JSON it writes:

{
  "base_branch": "main",
  "providers": {
    "amazon": {
      "current_version": "9.29.0",
      "commits": [
        {"hash": "c2dbd7a75a", "pr": "67987", "subject": "Fix IDC domain S3 path resolution",
         "classification": "needs_llm", "reason": "no high-confidence deterministic rule matched"},
        {"hash": "abc123", "pr": "68087", "subject": "Bump the edge-ui-package-updates group ...",
         "classification": "misc", "reason": "dependency bump (subject starts with 'Bump')"}
      ]
    }
  }
}

How to read it:

Providers under providers have pending changes (these need attention).
classification ∈ {documentation, skip, misc} are decided by rules — take them as-is, no sub-agent needed (doc-only → documentation, test/example only → skip, Bump … dependency bump → misc).
classification == needs_llm → Phase 3 decides with a sub-agent. These are the only commits that need LLM analysis.
A provider with a note/error (e.g. a brand-new provider with no prior release tag) → treat as an initial release and classify by hand.

[!NOTE] The classifier is deliberately conservative: Fix …/Add … subjects are not auto-classified (an "Add …" can be a breaking change), so they come back as needs_llm. The rules live in classify_change_deterministically (dev/breeze/src/airflow_breeze/prepare_providers/provider_documentation.py).

Then regenerate the auto-generated build files (this does no classification, so nothing random is produced):

breeze release-management prepare-provider-documentation \
    --reapply-templates-only --release-date "$RELEASE_DATE"
git checkout -- $(git diff --name-only -- '**/provider.yaml' '**/changelog.rst')

This leaves the regenerated build files (__init__.py, README.rst, pyproject.toml, conf.py, get_provider_info.py, index.rst) in place and discards only the changelog/version files Claude is about to rewrite itself.

Phase 2 — Per-provider commit list

For each provider in Success from Phase 1, get the same commit list that breeze would have shown. From the repo root:

PROVIDER_ID=<dotted.id>      # e.g. amazon, cncf.kubernetes
PROVIDER_PATH=$(echo "$PROVIDER_ID" | tr '.' '/')   # folder path: cncf/kubernetes
PROVIDER_TAG=$(echo "$PROVIDER_ID" | tr '.' '-')    # tag segment: cncf-kubernetes
# Pick the latest *final* release tag. Two gotchas the tag pattern must handle:
#  * dotted provider ids use HYPHENS in tag names (providers-cncf-kubernetes/<ver>),
#    even though the source folder uses slashes — build the tag prefix from
#    PROVIDER_TAG, not PROVIDER_PATH;
#  * skip the sentinel upper-bound tags (providers-<id>/99.98.0, /99.99.0) and rc
#    tags — git's default version sort orders "1.2.0rc1" AFTER "1.2.0", so a bare
#    `head -n1` would otherwise select a sentinel or a release candidate.
LAST_TAG=$(git tag --list "providers-${PROVIDER_TAG}/*" --sort=-v:refname \
    | grep -vE '/99\.9[0-9]\.' | grep -vE 'rc[0-9]+$' | head -n1)
git log --pretty=format:'%H %h %cd %s' --date=short \
    "${LAST_TAG}..apache-https-for-providers/main" \
    -- "providers/${PROVIDER_PATH}/"

[!WARNING] This git query is a convenience for building the per-provider commit list, but the authoritative set is what breeze prints in the Phase 1 "Commit" tables for each provider. The tag-based range can still diverge from breeze when a provider's most recent final tag is not the last actually-published release (for example, a wave commit bumped the version on main but the published baseline is older), which makes breeze include repo-wide commits this query misses. When the two disagree, trust breeze's list and reconcile against it before classifying.

Capture the full hash, short hash, date, subject, and #NNNN PR number for each commit. Note that some old providers also have legacy paths under airflow/providers/<id>/ — include those when present (consult provider_details.possible_old_provider_paths semantics by checking the provider's provider.yaml history if needed).

Phase 3 — Classify the PRs (inline, or batched per-provider sub-agents)

For each commit, classify it into one of:

Code	Meaning	Version bump
`d`	Documentation-only	none (patch if combined)
`b`	Bug fix	patch
`f`	Feature	minor
`x`	Breaking change	major
`m`	Misc (deps, refactors, internal only)	patch
`s`	Skip (test/CI/example only — no user impact)	none
`v`	Min Airflow version bump	minor (treated as misc + bump)

Take the deterministic classifications from Phase 1

classify-provider-changes (Phase 1) already classified every commit it could with hard-coded rules. Read /tmp/provider-changes.json and:

Use any commit whose classification is documentation, skip, or misc as-is — these map to d, s, m respectively; no sub-agent needed.
Only commits with classification: needs_llm go to a sub-agent (below).

The deterministic rules (doc-only → d, test/example-only → s, Bump … dependency bump → m) are exactly the cheap cases — now computed once by breeze (classify_change_deterministically) instead of re-derived here. If you ever need the min-Airflow-bump case (v), that one is still a needs_llm judgement: a sub-agent should flag it when a PR bumps the provider's minimum Airflow version.

[!NOTE] A needs_llm commit can still be classified as skip by the LLM. The deterministic classifier only catches test/example-only changes by looking at which files were modified in the commit. PRs that change build tooling, packaging infrastructure, or breeze templates (files under dev/breeze/, scripts/, etc.) and only regenerate template-generated files in the provider slice (e.g. README.rst, index.rst, pyproject.toml) are NOT caught by the deterministic rules but should still be classified as skip — they have zero user-facing impact on the provider package itself.

Classify the `needs_llm` commits — batched per provider, not one agent per PR

Only the commits the classifier returned as needs_llm still need a sub-agent. Classification is the token-heavy part of this skill, so spend sub-agents sparingly. Do not spawn one sub-agent per PR — that is one agent per commit and balloons to hundreds of agents on a normal release wave. Pick the smallest fan-out that fits the volume:

Few needs_llm commits remain (≲ 15 across all providers) → classify inline. Read each PR and its provider-scoped diff yourself, in this context. Spawn no sub-agents at all.
More than that → one sub-agent per provider. Each agent classifies that provider's entire remaining needs_llm list in a single pass. This is the natural unit: multi-provider PRs are classified independently per provider anyway (see Cross-Cutting Rules), and one provider-scoped agent amortizes the breaking-change checklist across all of that provider's commits instead of paying a fresh agent spin-up per commit. Only split a provider across more than one agent when its remaining list is large (> ~25 commits) — chunk it then. This keeps the sub-agent count at roughly the number of providers with pending changes, not the number of commits.

Use the Explore agent type — they need read-only access. Brief each sub-agent with its provider and the whole batch of commits it owns:

Classify a batch of Apache Airflow provider PRs for ONE provider.

Provider:  <provider-id>      (path: providers/<provider-path>/)
Commits to classify (<N>) — one row per PR:
  #<NNNN>  <full-hash>  <subject>
  #<MMMM>  <full-hash>  <subject>
  …(this provider's full remaining list)

For EACH commit above:
1. Read the PR's title, body, and labels:
   `gh pr view <NNNN> --json title,body,labels,files`
2. Read the diff for the slice of the PR that touched
   providers/<provider-path>/ only:
   `gh pr diff <NNNN> -- 'providers/<provider-path>/**'`
   (When the PR touches multiple providers, you only care about the slice
   for THIS provider — ignore the others when classifying.)
3. Decide a single classification:
   - documentation: only docs/comments/typos in the provider slice
   - bugfix:        fixes incorrect behavior, no API changes
   - feature:       adds new capability, parameter, operator, sensor, hook,
                    or extends an existing one in a backwards-compatible way
   - breaking:      see "Breaking-change checklist" below
   - misc:          dependency bumps, internal refactors, type-hint
                    cleanups, no user-visible behavior
   - skip:          only tests/examples/CI for this provider's slice,
                    OR changes that only touch build tooling, packaging
                    infrastructure, or template-generated files (e.g.
                    README.rst, index.rst, pyproject.toml regeneration,
                    flit/sdist config, breeze templates) — even when
                    those files live under the provider path. If the
                    PR's actual code changes are entirely in dev/breeze/
                    or similar tooling and the provider-scoped diff is
                    limited to regenerated docs/metadata, classify as
                    skip.
   - min_airflow_bump: explicitly bumps the minimum Airflow version pin
4. Set BREAKING_RISK to "maybe" whenever the diff has any signal from the
   breaking-change checklist below, even if you think the author intended
   otherwise.

Output one row per commit and nothing else, in this exact pipe format
(<N> rows for <N> commits):

   #<NNNN> | <documentation|bugfix|feature|breaking|misc|skip|min_airflow_bump> | <high|medium|low> | <none|maybe|yes> | <one-sentence justification>

Breaking-change checklist (any of these → BREAKING_RISK >= maybe; usually
breaking unless clearly behind a deprecation shim):
  * Public class/function/method removed or renamed
    in the **public interface** of the provider — i.e. files under
    `providers/<path>/src/**/{hooks,operators,sensors,triggers,
    notifications,decorators,executors}/**`, the provider's
    top-level package `__init__.py`, plus anything imported by
    `provider.yaml` (`hook-class-names`, `extra-links`, etc.).
    Internal helpers (e.g. `utils/`, `_internal/`, `pod_manager.py`,
    or any module not re-exported from the package or referenced
    in `provider.yaml`) are NOT breaking on their own. NOT in tests/.
  * Required parameter added to a public constructor or operator __init__
  * Default value of a public parameter changed
  * Return type or signature of a public method changed
  * `extra_dejson` / connection-form fields removed or renamed
  * Behavior change in `execute()`, `poke()`, `get_conn()` that produces
    different results for the same inputs
  * Minimum Python or Airflow version bumped (separate: that's
    min_airflow_bump unless the bump excludes a previously supported version
    of a provider's hard dependency, in which case it's also breaking)
  * Removed deprecation: a previously-deprecated symbol is now deleted
  * Schema change in stored data (xcom, connection, asset metadata,
    or the serialized state/context of a `BaseTrigger` subclass —
    deferred tasks survive provider upgrades only if the trigger's
    `serialize()` payload stays compatible)

Do NOT trust the PR title alone — read the diff. A PR titled "Refactor X"
that removes a public method is breaking. A PR titled "BREAKING: rename
foo" that only renames a private symbol is not.

Collect every sub-agent's rows (and any you classified inline) into one classification table for Phase 3.5.

Phase 3.5 — Confirm with the release manager

Print a per-provider summary in this exact format (so the release manager can scan it quickly):

Provider: amazon
Current version: 9.12.0
Most-impactful change: feature → next version: 9.13.0

Commits (12):
  abc1234  d   high   docs: fix S3 example                                  #65000
  def5678  b   high   Fix retry on transient SQS error                      #65010
  9ab0123  f   high   Add wait_for_completion to AthenaOperator              #65020
  4cd5678  x   med    Remove deprecated S3Hook.list_objects                  #65030  ⚠ BREAKING
  7ef9012  m   high   Bump aiobotocore to 2.13                              #65040
  ...
Uncertain: 2 commits below — please confirm:
  4cd5678  x   med    Remove deprecated S3Hook.list_objects (#65030)
    Why: list_objects is documented as deprecated since 8.0.0 but never
    raised DeprecationWarning, so removal may surprise users.
  abc4321  ?   low    "Refactor Athena client" (#65060)
    Why: PR description says non-breaking but diff changes the default
    region resolution from env to provider extras.

Always escalate to the release manager when:

CONFIDENCE: low from any sub-agent.
BREAKING_RISK: maybe but the sub-agent classified as anything other than breaking.
Same PR appears in multiple providers and got different classifications across them — explain why and let the RM call it.
Most-impactful change is breaking (major bump): always reconfirm explicitly before applying. Major bumps are never silent.

If the release manager corrects a classification, save it in your classification table and re-derive the most-impactful change.

Phase 4 — Apply classifications

For each provider, in order:

4a. Bump the version in `provider.yaml`

Open providers/<provider-path>/provider.yaml, find the versions: block, and prepend the new version. The bump rule (most-impactful classification across all commits for this provider, computed in Phase 3.5):

Most-impactful	Bump
`breaking`	major (X+1.0.0)
`feature`	minor (X.Y+1.0)
`min_airflow_bump`	minor (X.Y+1.0)
`bugfix`	patch (X.Y.Z+1)
`misc`	patch (X.Y.Z+1)
`documentation` only	no bump — handle as doc-only (see below)
`skip` only	no bump — nothing to do

Also update source-date-epoch: to the current int(time.time()).

For doc-only providers, do not bump the version. Instead, write the latest commit hash from the doc-only batch into providers/<provider-path>/docs/.latest-doc-only-change.txt (newline terminated). This is what breeze checks on the next release to know the provider hasn't really changed.

4b. Write the changelog entry

Open providers/<provider-path>/docs/changelog.rst. Insert a new section above the most recent existing version section. The exact format must match dev/breeze/src/airflow_breeze/templates/CHANGELOG_TEMPLATE.rst.jinja2 — don't paraphrase it. The skeleton:

<NEW_VERSION>
<dots matching length of NEW_VERSION>

.. note::
    This release of provider is only available for Airflow X.Y+ as explained in the
    Apache Airflow providers support policy <https://github.com/apache/airflow/blob/main/PROVIDERS.rst#minimum-supported-version-of-airflow-for-community-managed-providers>_.

Breaking changes
~~~~~~~~~~~~~~~~

* ``<commit subject for breaking change> (#NNNN)``

Features
~~~~~~~~

* ``<commit subject for feature> (#NNNN)``

Bug Fixes
~~~~~~~~~

* ``<commit subject for bugfix> (#NNNN)``

Misc
~~~~

* ``<commit subject for misc/min_airflow_bump> (#NNNN)``

Doc-only
~~~~~~~~

* ``<commit subject for doc> (#NNNN)``

.. Below changes are excluded from the changelog. Move them to
   appropriate section above if needed. Do not delete the lines(!):
   * ``<commit subject for skip> (#NNNN)``

Rules:

A .. note:: block at the top of the version section (directly under the <dots> underline, before the first ~~~ header) is used in two distinct situations. Include it whenever either applies — combine the wording into a single note, or stack two notes, when both do:
- Airflow min-version bump — when the bump was driven by a min_airflow_bump (or by a breaking whose breaking aspect is the Airflow min bump), use the support-policy wording shown in the skeleton.
- Breaking change — for every breaking classification (major bump, including a 0.x minor that ships a breaking change), add a note explaining what breaks and how users should adapt (the migration path). Write it from the PR description and the actual diff, not as a restatement of the commit subject — the reader must learn how to react without opening the PR. This mirrors the standing changelog convention ("only add notes … when there are some breaking changes and you want to add an explanation to the users on how they are supposed to deal with them"). The bullet under Breaking changes still lists the commit subject as usual; the note is in addition to it, not a replacement.
Drop a section entirely if it has no entries (e.g. no Breaking changes section if there were none — don't leave an empty header).
The .. Below changes are excluded ... block at the end is required even if empty. Lines under it use the indented ` * ``...``` form (three-space indent, double backticks).
Subjects must be the original commit subject with backticks replaced by single quotes (matches message_without_backticks). Don't paraphrase.
Strip Conventional Commit prefixes before writing to the changelog. If the subject starts with a prefix like feat:, fix:, chore:, docs:, refactor:, ci:, test:, perf:, build:, or style: (with or without a scope in parentheses, e.g. fix(amazon):), remove the prefix and capitalize the first letter of the remaining text. Example: refactor: Fix _is_http_client_closed ... → Fix _is_http_client_closed .... Airflow does not use Conventional Commits and these prefixes should not appear in changelogs.
Always keep the (#NNNN) PR suffix.

4c. Regenerate templates with breeze

Once all providers have their provider.yaml and changelog.rst updated, run:

breeze release-management prepare-provider-documentation \
    --reapply-templates-only \
    --skip-git-fetch \
    --release-date "$RELEASE_DATE"

This regenerates __init__.py, README.rst, pyproject.toml, conf.py, get_provider_info.py, and index.rst for every provider — picking up the new versions you just wrote. It will not touch changelog.rst.

[!NOTE] commits.rst per provider is also stable template content (the actual commit list is rendered at doc-build time via the airflow-providers-commits directive). It will be regenerated on the next full release. No action needed here.

4d. Resolve `# use next version` inter-provider pins

Contributors can defer an inter-provider dependency bump by pinning it in pyproject.toml with a trailing # use next version comment, instead of hard-coding a version that does not exist yet. Now that the versions are bumped, resolve those pins:

breeze release-management update-providers-next-version

This rewrites every # use next version dependency to the just-bumped version of the referenced provider and removes the comment.

[!IMPORTANT] Run this every time, before opening the PR — even when you believe no provider uses the comment (the command is a safe no-op when none do). Skipping it ships the wave with stale lower bounds on inter-provider dependencies; once the PR is merged the only remedy is a separate follow-up PR. This is the "Update versions of dependent providers to the next version" step in dev/README_RELEASE_PROVIDERS.md — it lives between doc preparation and PR creation, so it is easy to forget when the skill hands back to the regular release workflow.

Phase 5 — Validate

Run the same checks the release manager would run:

# RST lint + license headers + ruff on Python files
prek run --from-ref main --hook-stage pre-commit

# Spot-check that provider.yaml versions parse
breeze release-management prepare-provider-documentation \
    --reapply-templates-only --skip-git-fetch \
    --release-date "$RELEASE_DATE"   # idempotent — should be a no-op diff

Then git diff --stat and walk the release manager through the diff provider-by-provider:

Confirm the version in provider.yaml matches the bump rule.
Confirm changelog.rst has the right sections populated.
Check for misplaced top-level note blocks. Each provider's changelog.rst has a standing .. NOTE TO CONTRIBUTORS: RST comment near the top (above all version sections). If you detect any .. note:: directive that is NOT nested under a specific version section (i.e. it appears before the first version header, or between the Changelog heading and the first version), notify the release manager immediately — it likely means a breaking-change or min-version note was accidentally written at the wrong indentation level or position.
Confirm Phase 4d ran: no # use next version comment remains where the referenced provider was bumped in this wave.
Flag anything where Phase 3.5 had to escalate, so the RM can double-check.

Stop here. Do not commit, do not push — the release manager opens the PR themselves following the regular release workflow in dev/README_RELEASE_PROVIDERS.md. Make sure Phase 4d (update-providers-next-version) has been run before that PR is opened.

Incremental Update

Use this flow when the release PR has already been opened (changelog and version bumps applied via Phases 1–5) and the release manager rebases it to pick up commits that landed on main after the original classification. This is the equivalent of breeze release-management prepare-provider-documentation --incremental-update, but driven by the same AI classification logic as the initial run.

[!IMPORTANT] Run on the release PR branch after rebasing onto the latest base branch. Do not start the incremental flow on a clean checkout — it needs the prior classifications already written into changelog.rst to diff against.

Incremental Phase 1 — Refresh the apache remote

breeze release-management prepare-provider-documentation \
    --reapply-templates-only \
    --release-date "$RELEASE_DATE"

This re-fetches apache-https-for-providers/<base-branch> and regenerates the auto-generated build files for every provider — picking up any upstream template changes that landed since the original PR was opened. It does not touch provider.yaml or changelog.rst.

Incremental Phase 2 — Detect new commits per provider

For each provider that already has a new version section in its changelog.rst (the providers in the release PR), get the current commit list the same way as Phase 2 of the initial run:

PROVIDER_ID=<dotted.id>
PROVIDER_PATH=$(echo "$PROVIDER_ID" | tr '.' '/')   # folder path (slashes)
PROVIDER_TAG=$(echo "$PROVIDER_ID" | tr '.' '-')    # tag segment (hyphens)
# Same tag-selection rules as Phase 2: hyphenated tag segment, and skip sentinel
# (99.98.0/99.99.0) and rc tags so we compare against the last *final* release.
LAST_TAG=$(git tag --list "providers-${PROVIDER_TAG}/*" --sort=-v:refname \
    | grep -vE '/99\.9[0-9]\.' | grep -vE 'rc[0-9]+$' | head -n1)
git log --pretty=format:'%H %h %cd %s' --date=short \
    "${LAST_TAG}..apache-https-for-providers/main" \
    -- "providers/${PROVIDER_PATH}/"

Then identify new commits by comparing PR numbers to the existing changelog. A commit is "new" if its (#NNNN) PR suffix is not already present anywhere in providers/${PROVIDER_PATH}/docs/changelog.rst. This is exactly the same predicate breeze uses internally (see _generate_new_changelog append branch in dev/breeze/src/airflow_breeze/prepare_providers/provider_documentation.py).

CHANGELOG="providers/${PROVIDER_PATH}/docs/changelog.rst"
# pseudo: emit only commits whose #NNNN is NOT in the changelog
git log --pretty=format:'%H %h %cd %s' --date=short \
    "${LAST_TAG}..apache-https-for-providers/main" \
    -- "providers/${PROVIDER_PATH}/" \
  | python3 -c "
import re, sys
seen = open('${CHANGELOG}').read()
for line in sys.stdin:
    m = re.search(r'\(#(\d+)\)', line)
    if not m or f'(#{m.group(1)})' not in seen:
        print(line, end='')
"

If there are zero new commits for a provider, skip it.

Incremental Phase 3 — Classify the new commits

Same logic as Phase 3 of the initial run — including the auto-classify heuristic for docs/test-only changes and the batched classification (inline when few commits remain, otherwise one sub-agent per provider) with the breaking-change checklist. Incremental runs usually have only a handful of new commits, so prefer classifying them inline rather than spawning any sub-agent. The output is a per-provider table mapping each new commit hash to a classification.

Incremental Phase 3.5 — Decide whether to escalate the version bump

Compute the most-impactful classification across both the existing classified commits in the changelog and the new ones. If the most impactful is now stronger than what's already in provider.yaml, the version needs to be re-bumped. The escalation table:

Was bumped to	Now most-impactful is	Action
patch	`feature`	re-bump to next minor (X.Y+1.0)
patch	`min_airflow_bump`	re-bump to next minor (X.Y+1.0)
patch / minor	`breaking`	re-bump to next major (X+1.0.0)
minor	`feature`	no change — already minor
anything	`bugfix` or `misc`	no change

A re-bump means: replace the prepended version in provider.yaml AND update the version header in changelog.rst's new section to match.

Always confirm a re-bump with the release manager — explicitly state the old version, the new version, and which incoming commit forced the escalation. Don't silently re-bump.

Incremental Phase 4 — Apply the new entries

For each new commit, insert into the existing latest-version section of changelog.rst under the right header:

Classification	Section
`breaking`	`Breaking changes`
`feature`	`Features`
`bugfix`	`Bug Fixes`
`misc`	`Misc`
`min_airflow_bump`	`Misc`
`documentation`	`Doc-only`
`skip`	excluded block at end

If the section header doesn't exist yet (e.g. previously there were no breaking changes, but a new commit introduced one), create the header above the next existing section, matching the order in CHANGELOG_TEMPLATE.rst.jinja2: Breaking changes → Features → Bug Fixes → Misc → Doc-only.

If you re-bumped the version in Incremental Phase 3.5, also add or remove the .. note:: block about the Airflow min version requirement to match the new bump kind.

If a new commit is classified breaking, add (or extend) a .. note:: at the top of the version section explaining what breaks and how users should adapt, exactly as in the breaking-change note rule in Phase 4b.

Incremental Phase 5 — Validate

Same as Phase 5 of the initial run plus an extra check: confirm there are no leftover "Please review …" markers from a prior interactive breeze release-management prepare-provider-documentation --incremental-update run. If any are present (someone ran the breeze incremental flow before invoking this skill), remove them as part of the final pass. Then walk the diff with the release manager.

If the incremental run bumped a provider to a new version (Incremental Phase 3.5), re-run Phase 4d (update-providers-next-version) as well — a # use next version pin on that provider must resolve to the freshly bumped version before the rebased PR is pushed.

Cross-Cutting Rules

PRs covering multiple providers

When a single PR touches several providers (e.g. Add Python 3.14 Support (#63520) touches dozens), classify it independently per provider. The same PR can be feature in one provider (a real new capability) and misc in another (just a constraint bump in pyproject.toml). Always scope the diff inspection (whether inline or in a per-provider sub-agent) to the current provider's path:

gh pr diff <NNNN> -- 'providers/<provider-path>/**'

If the per-provider classifications come back different, do NOT try to "reconcile" them — that's a feature, not a bug. The release manager wants each provider's changelog to reflect what changed in that provider.

Asking the release manager — phrasing

When you ask, state your best guess and the alternative explicitly:

Provider amazon, commit 4cd5678 ("Remove deprecated S3Hook.list_objects" #65030): I classified this as breaking because the symbol is removed from the public API in providers/amazon/src/airflow/providers/amazon/aws/hooks/s3.py, even though the PR description says "deprecated since 8.0.0". Confirm breaking (major bump 9.x → 10.0.0) or override to misc (patch)?

Don't ask vague yes/no questions ("is this breaking?"); always offer the two alternatives with the version-bump consequence.

Things you must NOT do silently

Bump major version without explicit confirmation from the release manager.
Reclassify a commit the RM already confirmed.
Skip commits that don't fit a category — flag them as ? and ask.
Edit commits.rst, index.rst, __init__.py, README.rst, pyproject.toml, conf.py, get_provider_info.py directly. Those are template-generated by breeze.
Run git add or git commit — the release manager owns the PR.

When to give up and fall back to interactive breeze

If the per-provider commit count is huge (50+) and the sub-agents come back with low confidence on most of them (typically because the diffs require deep domain knowledge), tell the release manager you're stopping the AI classification and recommend they run the regular interactive breeze release-management prepare-provider-documentation for that specific provider. Don't try to power through guesswork — the wrong classification at major-bump granularity is worse than a slower manual run.
