Summary

The Google Gemini provider documentation did not state that NemoClaw filters embedding-only models (no generateContent support) out of the model catalog, and had no troubleshooting entry for the resulting validation error messages. This adds that statement to the Validation section and adds a new Troubleshooting entry documenting both error strings.

Related Issue

Fixes #8971

Changes

  • docs/inference/use-google-gemini.mdx: state in the Validation section that embedding-only models are filtered out of Google's native model catalog before matching, and link to the new troubleshooting entry.
  • docs/reference/troubleshooting.mdx: add a "Google Gemini rejects a curated or custom model" entry under Onboarding, documenting the Could not validate model against ... and Model '{model}' is not available from Google Gemini ... error strings and their causes, verified against src/lib/inference/provider-models.ts (validateGeminiModel, parseGeminiModelCatalogPage).

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with doc updates
  • Doc only (prose changes, no code sample modifications)
  • Doc only (includes code sample changes)

Quality Gates

  • Tests added or updated for changed behavior
  • Existing tests cover changed behavior — justification:
  • Tests not applicable — justification: docs-only change, no code behavior changed.
  • Docs updated for user-facing behavior changes
  • Docs not applicable — justification:
  • Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
  • Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification:
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: docs-updated
  • Evidence: docs/inference/use-google-gemini.mdx, docs/reference/troubleshooting.mdx. An independent Codex Desktop review covered the writing rules and documentation style. Both reciprocal links resolve in the generated OpenClaw, Deep Agents, and Hermes routes. npm run docs:check-routes and npm run docs passed.
  • Agent: Codex Desktop

Verification

  • PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub — commit a947d72db3e6e7e5c48be801cc300e2e2177196a is not verified (no_user)
  • Normal pre-commit, commit-msg, and pre-push hooks passed
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above — npm run docs:check-routes passed for 68 guarded pages
  • Applicable broad gate passed — not run because this pull request changes documentation only
  • Quality Gates section completed with required justifications or waivers
  • No secrets, API keys, or credentials committed
  • npm run docs builds without warnings (doc changes only) — the command exited 0 with 0 errors; two existing warnings report missing Fern authentication for redirects and the repository light-mode accent contrast
  • Doc pages follow the style guide (doc changes only)
  • New doc pages include SPDX header and frontmatter (new pages only) — N/A, no new pages

Summary by CodeRabbit

  • Documentation
    • Documented that Gemini embedding-only models are excluded from available catalog results and rejected during manual validation.
    • Added troubleshooting guidance for catalog request failures and invalid, unavailable, inaccessible, or unsupported model IDs.
    • Clarified that only models supporting content generation are available for matching.
    • Linked model validation troubleshooting from the Gemini integration documentation, including recovery guidance for curated and custom configurations.

…oting (NVIDIA#8971)

The Google Gemini provider page's Validation section did not mention that embedding-only models (no generateContent support) are filtered out of the model catalog. No troubleshooting entry documented the validation error messages a user hits when a Gemini model fails validation.

Document the embedding-only filter in the Validation section of use-google-gemini.mdx, add a new Troubleshooting entry covering both Gemini model-validation error strings, and link the two pages together.

2 terminology differences from the second opinion

Advisory only. These are normalized differences from the primary terminology receipt.

  • generateContent at docs/reference/troubleshooting.mdx:1261: selected only by the second-opinion lane as established.
  • embedding-only models at docs/inference/use-google-gemini.mdx:48: selected only by the second-opinion lane as justified.

Second-opinion terminology and E2E selections are advisory. Live E2E does not run automatically for pull requests.

2 semantic terminology decisions

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

  • justified — embedding-only model at docs/inference/use-google-gemini.mdx:48: Keep "embedding-only model" and define it by the missing generateContent capability where the distinction affects model selection.
  • established — native model catalog at docs/reference/troubleshooting.mdx:1259: Keep the established term and identify the Google endpoint when troubleshooting catalog validation.

E2E guidance

Advisory only. A maintainer can dispatch the default E2E suite for the commit under review.

Recommended E2E: None

Reviewed exact head a947d72. Documentation content is accurate and I found no blocking issue.

Reviewed commit 50d97e1. The documentation routes and required CI now pass, and I found no content blocker.

Blocking: commit a947d72 does not appear as Verified on GitHub (no_user). NemoClaw requires every commit in a contributor PR to appear Verified, and maintainers do not rewrite contributor history to repair this. Replace the unverified commit with compliant signed history. If the published branch cannot be rewritten, open a fresh branch and PR with compliant history.

I reviewed the complete diff at commit 50d97e1 and compared it with competing PR #9183 for issue #8971. This documentation is accurate and covers the required embedding-only filtering and validation messages, but the PR is not contributor-eligible: commit a947d72 is not GitHub Verified (reason: no_user).

Replace the branch history with commits that all appear Verified, then rerun the documentation receipt and required checks for the current PR commit if this candidate remains open. On the reviewed evidence, I recommend #9183 because it covers the same accepted scope, includes direct source regression tests, and passes contributor compliance. Do not merge both candidates.

PR #9183, the eligible implementation for issue #8971, has now merged. This PR is superseded and must not also merge. Please close it without merging; its unverified commit remains an independent contributor-compliance blocker.

Closing in favor of #9183, which was merged and covers the same scope (issue #8971) — thanks for the review and for pointing me to it, appreciate the direct comparison.
