What is Plugin Reviewer?

A code-review role for OpenWebUI plugin changes. It checks implementation against repository rules for translations, context access, event safety, file paths, uploads, and status messages.

Reviewing plugin code for internationalization, safe event handling, workspace path validation, upload fallbacks, context helpers, emitter guards, and failure reporting.

It catches release-blocking problems before code is shipped and keeps plugin changes aligned with established project conventions.

Plugin Reviewer — Agent for Claude Code by Fu-Jie/openwebui-extensions

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.00903
Opus 5.5	$0.00013	$0.00361
Sonnet 5.5	$0.00006	$0.00181
Haiku 4.5	$0.00003	$0.00090

Security

Grade A, and why

Plugin Reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Review Checklist

🔴 Blocking (must fix before release)

1. Single-file i18n Architecture

No new _cn.py split files created.
All user-visible strings go through TRANSLATIONS[lang].get(key, fallback).
FALLBACK_MAP covers at least zh → zh-CN and en → en-US.
format(**kwargs) on translations wrapped in try/except KeyError.

2. Context Helpers

Uses _get_user_context(__user__) (not __user__["name"] directly).
Uses _get_chat_context(body, __metadata__) (not ad-hoc body.get("chat_id")).

3. Antigravity Safety

Every __event_call__ wrapped: asyncio.wait_for(..., timeout=2.0).
JS code passed to __event_call__ has try { ... } catch(e) { return fallback; }.
File path operations validated against workspace root (no traversal).
Upload paths have dual-channel fallback (API → DB/local).

4. Emitter Guards

Every await emitter(...) guarded by if emitter:.
_emit_status(done=False) on start, done=True on success, _emit_notification("error") on failure.
No bare print() — use logging.getLogger(__name__).

5. Filter Singleton Safety

No mutable per-request state stored on self in Filter plugins.

6. Streaming Compatibility (OpenWebUI 0.8.x)

</think> tag closed before any normal text or tool cards.
<details type="tool_calls" ...> attributes escape " as ".
<details ...> block has newline immediately after >.

7. Version & Docs Sync

Version bumped in docstring (if release).
README.md + README_CN.md updated (What's New + version).
docs/plugins/{type}/{name}.md and .zh.md match README.
docs/plugins/{type}/index.md and .zh.md version badges updated.
Root README.md / README_CN.md date badge updated.

8. Knowledge Capture

Any non-obvious findings (API contracts, injection quirks, gotchas) documented in .agent/learnings/{topic}.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Plugin Reviewer is an agent published in the GitHub repository Fu-Jie/openwebui-extensions (326 stars, last pushed 8d ago), licensed MIT. It adds 32 tokens to every session and 903 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
