Update integrations PRs

Process contributor integration docs PRs in langchain-ai/docs so they match the hosted-guide eligibility rules from #4865.

For new listings filed as GitHub issues (issue form + integration-submission label), use the submit-integration skill instead. That path creates listing changes for CI to open a PR.

Policy source: src/oss/contributing/publish-langchain.mdx and src/oss/contributing/integrations-langchain.mdx.

Workflow checklist

Copy and track:

- [ ] Identify PR + package name(s)
- [ ] Report monthly downloads (PyPI and/or npm)
- [ ] Decide: hosted/feature vs external
- [ ] Rebase onto upstream/main (keep contributor commits)
- [ ] Apply conversion in a **separate** commit
- [ ] Verify net diff vs main
- [ ] Report result; do **not** push unless asked

1. Inspect the current branch

git branch --show-current
gh pr view --json number,title,url,author,maintainerCanModify,files,body
git diff --stat upstream/main...HEAD

Find the LangChain-related package name(s) from packages.yml, MDX install snippets, or registry metadata. Ignore unrelated packages with similar names.

2. Measure downloads

PyPI (last ~30 days, no mirrors):

curl -s "https://pypistats.org/api/packages/<pkg>/overall?mirrors=false" \
  | python3 -c "import sys,json; d=json.load(sys.stdin); data=d.get('data',[]); last30=data[-30:] if len(data)>=30 else data; print(sum(x.get('downloads',0) for x in last30))"
curl -s "https://pypistats.org/api/packages/<pkg>/recent"

npm (last month):

curl -s "https://api.npmjs.org/downloads/point/last-month/<pkg>"

Report the number to the user before converting when they asked for downloads only.

3. Rebase

git fetch upstream main
git rebase upstream/main

• Keep contributor commits; put the conversion in a new commit after rebase.
• On heavy merge history, cherry-pick content commits onto upstream/main, then convert.
• Drop obsolete Card grids that main replaced with IntegrationDownloads.
• Drop redirects for pages that were never on main.
• Drop unrelated packages.yml download-count churn from bot commits.

4a. External conversion (under 50K)

1. Delete hosted MDX (component page and provider page if present).

2. Add YAML under the correct language + component in scripts/data/integration_external_docs.yaml:

   - name: ClassOrDisplayName
     pypi: langchain-example   # or npm: "@org/pkg" under javascript:
     docs_url: https://partner.example/docs

   Prefer partner docs, then public GitHub/GitLab README, then PyPI/npm.

3. Downloads snippet (sort by data-sort-value): add a row to the matching src/snippets/oss/*-*-downloads.mdx (for example python-sandboxes-downloads.mdx). Match existing badge markup.
4. all_providers: card with external href (alphabetical). Use icon="link" or an existing provider icon. Card body max 160 characters. If a draft description is longer, shorten it to one factual sentence ≤160 characters; do not invent claims. Limit: PROVIDER_CARD_DESCRIPTION_MAX_LEN in scripts/provider_card_limits.py.
5. packages.yml: append only for a public LangChain-related package. Ensure a trailing newline before appending. Omit path: .. Skip if the source repo is private or not a normal public VCS listing.
6. Nav / redirects: remove docs.json entries and redirects for deleted never-on-main pages. Do not add redirects for pages that never shipped.
7. Deep Agents / indexes: if the PR added provider cards that main no longer uses, prefer downloads tables and index grids; keep brief mentions only when main already lists providers that way.

Align listings with partner docs, not stale PR page counts.

4b. Hosted / featured path (≥50K or override)

1. Keep (or fix) hosted MDX; test code examples when touching them.
2. Frontmatter: follow templates under src/oss/*/integrations/**/TEMPLATE.mdx. Do not set featured: true unless a maintainer asked.
3. Prefer langchain imports over langchain_core when editing kept pages.
4. For featuring: set highlight: true in packages.yml only when asked; regenerate overview with the partner package table tool, do not hand-edit overview.mdx.
5. Update src/docs.json if adding a page that should stay.

5. Commit and handoff

• Conversion commit message focuses on why (threshold / external listing / feature).
• Show git diff --stat upstream/main...HEAD and downloads in the summary.
• Note maintainerCanModify for push later.
• Do not push unless the user asks. Use force-with-lease after rebase when pushing to the PR head.
• If maintainerCanModify: false, say so and ask whether to open a replacement PR.

Hard rules

• Ask for clarification rather than assuming package identity or feature overrides.
• Never fabricate download counts, docs URLs, or package names.
• Never edit build/.
• Never hand-edit generated overview tables.
• When appending to packages.yml, ensure a trailing newline first.
• Run make lint_prose FILES="..." on changed MDX before handoff when prose changed.
• Follow repo git safety: no bare git push; no force to main; no commit unless asked (except when the user said "go" / "next branch" for this workflow, commit the conversion).
