Greptile Summary

This PR fixes two broken anchor links in the Anthropic provider documentation (EN and zh-CN). The old links pointed to /gateway/troubleshooting#oauth-token-refresh-failed-anthropic-claude-subscription, an anchor that no longer exists after the troubleshooting page was restructured. The fix removes the stale fragment so both links now resolve to /gateway/troubleshooting without a 404-style anchor miss.

• Verified the anchor oauth-token-refresh-failed-anthropic-claude-subscription does not appear anywhere in docs/gateway/troubleshooting.md.
• Change is minimal, scoped to exactly two lines (one per locale), and all surrounding content is untouched.
• ja-JP locale correctly has no providers/anthropic.md and therefore requires no change.

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, correct docs-only fix with no logic or behavior changes.
• The anchor target was verified to not exist in the troubleshooting page. Removing it is the appropriate fix. The change touches only two documentation lines across two locale files, with no risk of regression.
• No files require special attention.

Did a force-pushed to update the wrong Author and Email address :)

Closing this as implemented after Codex review.

Current main already supersedes this docs-only PR: the Anthropic provider page was rewritten, the stale troubleshooting anchor no longer exists anywhere under docs/, and the repo no longer carries localized docs in docs/<locale>/**.

What I checked:

• Current Anthropic doc no longer uses the stale anchor: docs/providers/anthropic.md now has its own troubleshooting section and a generic help note linking to /help/troubleshooting and /help/faq, with no /gateway/troubleshooting#oauth-token-refresh-failed-anthropic-claude-subscription link. (docs/providers/anthropic.md:277, 4737a86071e3)
• Broken anchor string is gone from current docs tree: A repo search for oauth-token-refresh-failed-anthropic-claude-subscription under docs/ returned no matches, so the reported broken anchor is not present on current main. (7d9172d5e093)
• Current troubleshooting page is a new runbook, not the old anchor target: docs/gateway/troubleshooting.md on current main is a newly created troubleshooting runbook with sections like ## Command ladder and ## Anthropic 429 extra usage required for long context; the old anchor target from the PR body is not part of this page. (docs/gateway/troubleshooting.md:14, 4737a86071e3)
• Localized doc path from the PR is obsolete in this repo: The docs guide now states that foreign-language docs are not maintained in this repository and docs/<locale>/** should not be edited here, which matches the absence of docs/zh-CN/providers/anthropic.md on current main. Public docs: docs/AGENTS.md. (docs/AGENTS.md:21, 7d9172d5e093)

So I’m closing this as already implemented rather than keeping a duplicate issue open.
