Repeated prompt calling upon

[eagadmin123]

Hi,

We’ve noticed that the proxy sometimes behaves unexpectedly in OpenCode. It repeatedly returns the same output, as if it’s stuck in a loop.

For example, if the initial response is something like “Let me analyze it…”, the same line keeps getting returned over and over again, resulting in an apparent infinite loop.

Could you please investigate this issue and help resolve it?

Thanks.

Yes let me look into this and see where the leak is coming from. Can you confirm what version you are seeing this in? @eagadmin123

[rynfar]

@eagadmin123 - perfect thank you this is exactly what i need to debug. I'll dig in to whats going on.

[rynfar]

@eagadmin123 The logs show resume=false on every request — that's an old log format from before the session management overhaul. What version are you running? (check package.json in your meridian directory)

What's happening: without session resume, every turn replays your entire 180+ message conversation as flat text into a fresh SDK session. The model sees a wall of replayed history and loops on the same response.

Current version (1.22.0) has lineage-based session tracking that avoids this — it resumes the SDK session and only sends new messages, not the full replay. Upgrading should fix it.

Also noticed your config has two proxy instances on ports 3456 and 3457 — make sure both are running the same version. If one is outdated you'll hit this on whichever provider OpenCode routes to.

[eagadmin123]

@rynfar This issue usually occur if use 1 model in session and then change to opus 4.6 and send new message with opus model.

Do you know any plugin that will manage session properly.

both containers using image: meridian

version was: 1.15 (repo) but the docker image i pulled is latest.

[ianjwhite99]

@eagadmin123 I took a glance through your opencode.json. You appear to be using the opencode-with-claude plugin. Due to the plugin spawning it's own independent proxy processes, you are unable to run the plugin and proxy concurrently.

{
   "$schema":"https://opencode.ai/config.json",
   "plugin":[
      "@tarquinen/opencode-dcp@latest",
      "opencode-with-claude"
   ],
   "provider":{...}
}

You'll either need to remove the plugin and operate the proxy independently or update the plugin version by running

npm install -g opencode-with-claude@latest

[eagadmin123]

I gave you outdated opencode.json

Here's updated opencode.json

Error im getting that

• Somtimes it output the tool calling process. it doesn't actually call the tool rather it just output

Output of docker container

[PROXY] b27fa8cc-6aa8-4324-8da2-762f76d9de0c model=sonnet stream=true tools=33 resume=false active=1/10 msgs=user[text,text] → assistant[text,tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[tool_use] → user[tool_result] → assistant[text,tool_use,tool_use,tool_use,tool_use] → user[tool_result,tool_result,tool_result,tool_result] → assistant[text,tool_use] → user[tool_result] → assistant[tool_use] → user[tool_result] → assistant[text,tool_use] → user[tool_result,text]

NOTE:
with other models (from opencode) it's working perfectly fine.

• Secondly, same issues as i mention before. Repeated Initial Prompt Issue.
  It happen on two cases:

1. If i start using that proxy in the middle of a session that was not initial created by that same proxy claude
2. if i create new session and attach an image, then i face with such issue.

• Thirdly, im getting error, if i run command compose pull

git remote -v output

[rynfar]

Thanks for all the detail — the logs and config were really helpful. There are actually three separate things going on here, so let me address each one.

---

1. The looping / repeated responses

The root cause is visible in your proxy logs: every request shows resume=false. That's the log format from a version before session management was built. Current versions log lineage=continuation, lineage=new, etc.

What's happening without session tracking: every turn replays your entire conversation history as flat text into a fresh SDK session. By the time you have 180+ messages, the model is receiving a massive wall of replayed history on every request and gets confused, looping on the same output.

Both specific triggers you mentioned follow from this:

• Switching models mid-session — no lineage data exists for the previous session, so the proxy can't resume it and replays everything
• New session with an image attached — fingerprinting doesn't match cleanly when the first message contains image content, same outcome

Fix: You're running a stale Docker image. You mentioned version 1.15, and pulling latest hasn't updated it because you're building locally. Rebuild from the current main branch:

docker compose build --no-cache
docker compose up -d

Session tracking has been in place since 1.22.0 — once you're on current, the looping should stop entirely.

---

2. Playwright tools showing as text instead of executing

You have 33 tools registered — those are your Playwright MCP tools coming through from OpenCode. In Meridian's default (internal) mode, the proxy creates its own MCP server with the 6 standard file system tools and restricts Claude to only those. Playwright tools aren't implemented on the proxy side, so Claude sees them defined but can't call them — it falls back to describing the tool call as text instead.

This works fine with non-Anthropic models because those don't go through Meridian at all — OpenCode handles tool execution directly for them.

Fix: Run Meridian in passthrough mode. In that mode, Claude returns tool calls to OpenCode, and OpenCode handles execution — including Playwright, Exa, or any other MCP tools you have configured:

MERIDIAN_PASSTHROUGH=1 meridian

Or in your Docker setup, add MERIDIAN_PASSTHROUGH=1 as an environment variable in your compose file.

---

3. docker compose pull error

This isn't a Meridian bug. Your compose file uses image: meridian which refers to a locally-built image, not one published to Docker Hub. docker compose pull looks for it in a remote registry and won't find it. Use docker compose build instead (as above).

---

You're also running two proxy instances (ports 3456 and 3457) — make sure you rebuild both and that both have the same environment configuration, especially if you're enabling passthrough mode.
