In the @packages/opencode/src/share/share-next.ts , there is an handshake with the api server where a secret key is received after supplying the session-id.

Does this secret key derived from the session key? I changed it at some point to use a "shared key" with the backend server, but I cant remember if I did that just so that I could use that to perform manual api calls..

Can you check that out, and maybe have a look into why the sessions are not sharing currently with the server projects we have in @packages/sessions/

Instructions from: /home/jm/data/code/opencode/packages/opencode/AGENTS.md # opencode agent guidelines

Build/Test Commands

  • Install: bun install
  • Run: bun run --conditions=browser ./src/index.ts
  • Typecheck: bun run typecheck (npm run typecheck)
  • Test: bun test (runs all tests)
  • Single test: bun test test/tool/tool.test.ts (specific test file)

Code Style

  • Runtime: Bun with TypeScript ESM modules
  • Imports: Use relative imports for local modules, named imports preferred
  • Types: Zod schemas for validation, TypeScript interfaces for structure
  • Naming: camelCase for variables/functions, PascalCase for classes/namespaces
  • Error handling: Use Result patterns, avoid throwing exceptions in tools
  • File structure: Namespace-based organization (e.g., Tool.define(), Session.create())

Architecture

  • Tools: Implement Tool.Info interface with execute() method
  • Context: Pass sessionID in tool context, use App.provide() for DI
  • Validation: All inputs validated with Zod schemas
  • Logging: Use Log.create({ service: "name" }) pattern
  • Storage: Use Storage namespace for persistence
  • API Client: The TypeScript TUI (built with SolidJS + OpenTUI) communicates with the OpenCode server using @opencode-ai/sdk. When adding/modifying server endpoints in packages/opencode/src/server/server.ts, run ./script/generate.ts to regenerate the SDK and related files.

There's an enterprise package with share.ts in upstream. Let me look at the upstream server-side share implementation:

Now I have a complete understanding. Let me also check the API_DOMAIN value more closely — it includes /api in the URL already or not:

Looking at the test (line 179): expect(data.url).toBe('https://opencode.j9xym.com/share/n-abc123') but the actual code (line 78) produces ${c.env.API_DOMAIN}/api/share/${shareID} which with API_DOMAIN = "https://opencode.j9xym.com" gives https://opencode.j9xym.com/api/share/n-abc123.

Wait, that's actually wrong! The test expects /share/ but the code produces /api/share/. Let me re-read the test:

00174|   test("creates share with valid sessionID", async () => {

So the test expects https://opencode.j9xym.com/share/n-abc123 but the code on line 78 produces ${c.env.API_DOMAIN}/api/share/${shareID} = https://opencode.j9xym.com/api/share/n-abc123. That's a URL mismatch — but wait, this is the test. Does the test actually pass? Let me check:

The test timed out. Let me check what the actual URL output would be. Let me trace this through:

The API_DOMAIN in wrangler.jsonc is "https://opencode.j9xym.com" and the code does:

url: `${c.env.API_DOMAIN}/api/share/${shareID}`

which gives https://opencode.j9xym.com/api/share/{id}.

But the test expects: https://opencode.j9xym.com/share/n-abc123

This means either: (a) the test was written expecting a different URL pattern and is currently failing, or (b) it was updated and the URL was changed in the code but not matching. Let me check if there's been a recent edit:

Yes I just updated the API_DOMAIN, because it didnt seem correct to include the /api component on the end, and that that should be part of the routing done by the worker

claude-opus-4-6 · anthropic

Good call — that makes sense. The API_DOMAIN should just be the base domain, and the worker handles the path routing. Let me check the current state of things after your change and trace through the implications.

OK so the current state is:

  • wrangler.jsonc: API_DOMAIN = "https://opencode.j9xym.com" (no /api — good, that's your fix)
  • index.tsx line 78: still constructs url: \${c.env.API_DOMAIN}/api/share/${shareID}``

So with your API_DOMAIN fix, the returned URL is now https://opencode.j9xym.com/api/share/{id}. But there's still a question: is this URL intended to be the browser-viewable share page or the API data endpoint?

Let me check what the CLI does with the returned url field and what the HTML share route is:

# opencode agent guidelines

## Build/Test Commands

- **Install**: `bun install`
- **Run**: `bun run --conditions=browser ./src/index.ts`
- **Typecheck**: `bun run typecheck` (npm run typecheck)
- **Test**: `bun test` (runs all tests)
- **Single test**: `bun test test/tool/tool.test.ts` (specific test file)

## Code Style

- **Runtime**: Bun with TypeScript ESM modules
- **Imports**: Use relative imports for local modules, named imports preferred
- **Types**: Zod schemas for validation, TypeScript interfaces for structure
- **Naming**: camelCase for variables/functions, PascalCase for classes/namespaces
- **Error handling**: Use Result patterns, avoid throwing exceptions in tools
- **File structure**: Namespace-based organization (e.g., `Tool.define()`, `Session.create()`)

## Architecture

- **Tools**: Implement `Tool.Info` interface with `execute()` method
- **Context**: Pass `sessionID` in tool context, use `A...

Good, analysis saved. Here's the summary:

Answer: Secret Key Derivation

Yes, the secret is derived from the session ID — and this was your intentional change. In packages/sessions/src/index.tsx line 72:

const shareSecret = uuidv5(sessionID, c.env.SESSIONS_SHARED_SECRET)

It's a deterministic UUIDv5 using the sessionID as the name and your SESSIONS_SHARED_SECRET wrangler secret as the namespace. Upstream uses crypto.randomUUID() (fully random per share). Your change means you can recompute the secret locally from any sessionID + your shared secret, which is exactly what enables manual API calls without needing to look up stored credentials.

Why Sessions Aren't Sharing

There are three issues, in order of severity:

1. Likely blocker: Cloudflare WAF / Bot Fight Mode (silent failure)

Your AGENTS.md explicitly warns about this. If Bot Fight Mode is active on j9xym.com, the CLI's POST /api/share gets an HTML challenge page. The CLI does .then(x => x.json()) which throws, but there's zero error handling — the share record never gets stored locally, and every subsequent sync call silently bails via if (!share) return.

Quick test: curl -v -X POST https://opencode.j9xym.com/api/share -H "Content-Type: application/json" -d '{"sessionID":"test123"}' — if you get HTML or 403, that's it.

2. URL cosmetic issue (line 78)

Now that API_DOMAIN is correctly https://opencode.j9xym.com, the returned URL is https://opencode.j9xym.com/api/share/{id} — but this is the JSON data endpoint. The human-viewable HTML page is at /share/{id}. The test expects /share/ not /api/share/. This doesn't break sync but means the URL printed to the user opens raw JSON instead of the rendered session.

3. No fetch error handling in share-next.ts

Neither create(), sync(), nor remove() check response.ok. Any failure (WAF, timeout, 500) is silently swallowed.

userFeb 8, 10:04:43 PM

Everything alright?

assistantFeb 8, 10:04:43 PM
claude-opus-4-6 · anthropic

Yeah, everything's fine! I was just having trouble with the Write tool throwing a TypeError — seems like an intermittent tooling issue, not a code problem. I worked around it by writing the analysis file via bash instead. The file saved successfully at .Claude/assistant/share-secret-and-sync-analysis.md.

To recap where we landed:

  1. Your secret change was intentional and sound — deterministic UUIDv5 derivation so you can compute secrets offline for manual API calls. No issue there.

  2. The likely reason sharing isn't working is Cloudflare WAF/Bot Fight Mode silently eating the CLI's POST requests. The fastest way to confirm is:

    curl -v -X POST https://opencode.j9xym.com/api/share \
  -H "Content-Type: application/json" \
  -d '{"sessionID":"test123"}'

    If that comes back with HTML or a 403 instead of JSON, that's your answer.

  3. Minor fix needed on line 78 of packages/sessions/src/index.tsx — the URL should be /share/${shareID} not /api/share/${shareID} (viewable page vs raw JSON endpoint). Your API_DOMAIN fix was correct, this is just the path portion.

Want me to dig into anything else, or shall we move on to fixing these?

3in / 334out
userFeb 8, 10:08:09 PM

But does the opencode app itself depend on knowing how the secret key is derived, or does it need the secret key stored locally alongside the session data in order to sync it?

The answer is clear:

The CLI has no idea how the secret is derived. It treats it as an opaque token.

The flow is:

  1. create() — POSTs the sessionID to the server, gets back { id, secret, url }
  2. Stores that entire response locally via Storage.write(["session_share", sessionID], result) (line 80)
  3. sync() — reads the stored record via get(sessionID) (line 135), then sends share.secret in the request body (line 144)
  4. remove() — same pattern, reads stored secret (line 155), sends it in the delete body (line 163)

The CLI never computes or derives the secret. It just receives it from the server and replays it back on subsequent calls. The derivation method (UUIDv5 vs random) is entirely a server-side detail — the CLI would work identically with either approach.

So the deterministic derivation is purely for your convenience when making manual API calls outside the CLI. The CLI itself just needs the stored { id, secret, url } record from the initial create handshake.

FOr example, if the share data is lost from the local storage, but you know the session id, there is no way to sync again with that session data through the api?

Correct. With the upstream design (crypto.randomUUID()), you'd be completely stuck — the secret is gone, you can't sync or delete, and the server has no "re-auth" mechanism.

With your UUIDv5 design, you can recover — but only because you know the SESSIONS_SHARED_SECRET on the server side. If you have both the sessionID and that wrangler secret, you can recompute the exact same secret locally:

import { v5 as uuidv5 } from "uuid"
const secret = uuidv5(sessionID, SESSIONS_SHARED_SECRET)
const shareID = sessionID.slice(-8)

Then you can manually call sync/delete with curl. But there's no API endpoint to do this automatically — no "re-create" or "recover credentials" route. The CLI itself has no knowledge of the shared secret, so it can't self-recover either.

So to answer your question directly: through the API as it exists today, no — there's no way for the CLI to re-establish sync for a lost share. The CLI would just silently stop syncing (the get() returns nothing, sync() bails). The user would need to create a new share, which creates a new shareID and new R2 entries.

The UUIDv5 derivation gives you a manual escape hatch that upstream doesn't have, but the CLI doesn't leverage it. If you wanted the CLI to be self-healing, you'd need either:

  • A server endpoint like POST /api/share/recover that accepts just the sessionID and returns the credentials (but that's unauthenticated, so anyone with a sessionID could get the secret)
  • Or have the CLI re-call create() and have the server return the existing credentials if the share already exists (right now it just overwrites with a fresh empty session)
