Claude / Claude Code Review

Non-existent model ID claude-opus-4-7 will break workflows 

The model ID `claude-opus-4-7` does not exist — the latest released Opus model is `claude-opus-4-6`. Passing this via `--model` will cause the Anthropic API to reject every request with a model-not-found error, breaking both the PR review workflow and the @claude mention workflow on every invocation. The same invalid ID is also set in `.github/workflows/claude.yml` line 39; revert both to `claude-opus-4-6`.

🔴 The model ID claude-opus-4-7 does not exist — the latest released Opus model is claude-opus-4-6. Passing this via --model will cause the Anthropic API to reject every request with a model-not-found error, breaking both the PR review workflow and the @claude mention workflow on every invocation. The same invalid ID is also set in .github/workflows/claude.yml line 39; revert both to claude-opus-4-6.

Extended reasoning...

What the bug is

This PR changes the --model flag in two workflow files from claude-opus-4-6 to claude-opus-4-7. However, claude-opus-4-7 is not a valid Anthropic model ID. The most recent Claude model family is 4.5/4.6, and the latest released Opus model is Opus 4.6 with ID claude-opus-4-6. No Opus 4.7 model has been announced or released.

Code path that triggers it

The claude_args input is passed verbatim to the Claude Code CLI. In both workflows:

claude_args: |
  --allowedTools "..."
  --model "claude-opus-4-7"

The action forwards --model claude-opus-4-7 directly to the CLI, which sends it as the model parameter in the Messages API request. The Anthropic API validates model IDs strictly and returns a 404 not_found_error ("model: claude-opus-4-7") for unknown IDs.

Why nothing prevents it

Grepping the entire repository for opus-4-7 or 4.7 returns only the two lines this PR introduces — there is no model alias table, no validation layer, no fallback, and no documentation or CHANGELOG entry referencing a 4.7 model. The action does not validate or remap the model string; it is a pass-through.

Impact

  • .github/workflows/claude-review.yml runs on every pull_request: opened event → every newly opened PR will get a failed review job instead of a code review.
  • .github/workflows/claude.yml runs on every @claude mention in issues/comments/reviews → every user invocation will fail with an API error.

Both workflows become 100% non-functional immediately after merge.

Step-by-step proof

  1. PR is merged with --model "claude-opus-4-7".
  2. A contributor opens a new PR → claude-review.yml triggers.
  3. The action invokes claude --allowedTools ... --model claude-opus-4-7.
  4. The CLI sends POST /v1/messages with "model": "claude-opus-4-7".
  5. API responds: {"type":"error","error":{"type":"not_found_error","message":"model: claude-opus-4-7"}}.
  6. The CLI exits non-zero, the workflow step fails, no review is posted.
  7. The same happens for any @claude comment via claude.yml.

Fix

Revert both lines to --model "claude-opus-4-6" (the actual latest Opus). If the intent is to upgrade when 4.7 ships, this PR should be held until that model ID is live in the API.
